According to one embodiment, a plurality of base station transceivers (BTS) broadcast content data to a plurality of client stations of a network. This network can be, for example, a single frequency network (SFN, single frequency 200930112 ❹ r ). For example, “sfn” refers to a network that can simultaneously broadcast the same signal (ie, the same content) on the same channel from multiple transmitters (eg, BTS). Furthermore, as used herein, "content data refers to any material about any information that may be of interest to the user" such as, for example, audio (eg, music, speech, etc.), visual (eg,. Pictures, videos, movies, television, etc.), text (eg, paperwork documents, spreadsheets, etc.), or other types of information about the inner valley that may be of interest to the user. As used herein, the term broadcast service refers to a collection of broadcast content material. For example, in an embodiment, the client system may subscribe to a specific broadcast service including __ or multiple channels of audio/video content data, such as, for example, a multi-channel (eg, CNN, Foss) (F〇x) news, etc.), for a plurality of TV channels (eg, WABC, wnbc, etc.) for a specific place, a plurality of sports channels (eg, ESPN) H, the channel of this set may be, for example, - Application Service Provider (ASP, appHeatiGn serviee bribe) or other content providers, and the content data for each channel uses a common type of encoding (eg MPEG) and resolution (eg: for It is encoded by the low resolution of the display of the mobile phone, the high resolution for high-definition television, and the like. In one embodiment, the BTS system constructs a broadcast content material to a client station, and utilizes a macro-diversity (or broadcast) area of a downlink frame of one of the communication signals transmitted by the BTS. As used herein, the term "macro-diversity region" refers to a portion of a data frame that can be applied to broadcast information.

Furthermore, as used herein, the term "macro-diversity region" is interchangeable with the ‘‘broadcast region". According to one embodiment, each BTS of the broadcast content material broadcasts a management message, such as, for example, a media access control (MAC) message, which includes information identifying the broadcast content material. For example, the management message may include a broadcast channel identifier (CID) to identify a particular content material that is recognized by the broadcast CID. For example, the BTS can broadcast a MAC e-information heart including one of the broadcast CIDs, and the broadcast ciD system recognizes that the specific broadcast service (ie, the content material associated with the special broadcast service) is included in the BTS. A macro-diversity area that is broadcast. In one embodiment, the MAC management message is broadcast in an area of the data frame that is typically used to transmit other types of MAC messages, which is relative to the macro-diversity area of the data frame. In an embodiment, the MAC message may include additional information such as, for example, identifying the encoding pattern used to encode the data, the resolution of the content material, and the specific channel for broadcasting to the macro diversity region.

For the purpose of explanation, the content data provided will be described as audio/visual materials. Moreover, in one embodiment, each of the provided IP streaming systems may include content material for a particular audio/visual channel, such as, for example, one or more ιρ streaming systems may include content material to provide television news programs. (eg: cnn, blessing, broadcast movies, etc.), one or more IP streaming systems can provide one or more IP streaming systems that can be provided to send sports programs, a "1 wind cargo I The service n is identified by a single broadcast channel identifier (CID). As mentioned above, a broadcast service refers to a collection of content material that can be encoded into a particular file using a commonly used beta scheme such as, for example, MPEG. Resolution (for example: name 200930112 - low resolution for small screens such as mobile phones, high resolution for high definition television (HDTV), etc.). This broadcast CID can be followed by the client station. 132 is used to determine whether the broadcast content material contains content data that the client station desires to receive (for example, the broadcast content data is an example of a broadcast service subscribed to the client station) In one embodiment, there may be multiple ASPs 160 each of which provides a different broadcast service, wherein a client station 132 may only receive and provide content material belonging to a particular broadcast service.

In addition, in one embodiment, the encapsulator module 116 can be a packet (e.g., a transport packet) with an -IP header before the packet of the package is output. The encapsulator module 116 can then provide a transfer packet to the macro-division area control module 150. The macro-diversity area control module 15 can then packetize the transfer frames for broadcast to the client station 132. In addition, in an embodiment, the macro-diversity area control module 15G can further insert time stamping (handle (four)) information into the received transport packet. The timestamp information attached to the transport packet (e.g., the deleted transport packet) can be used by the BTS to enable individual BTSs 130 to transmit the time synchronized content data to the client station m so that each BTS 13G system simultaneously transmits Content material. Furthermore, in one embodiment, the 'large A set area control mode, the group 15" can further combine a plurality of receive transport packets into a larger box (referred to herein as "the giant box (coffee (four) letter e)") For transmission by the BTS 130. In one embodiment, the macro-diversity region control module 15 defines a large 200930112 _division region' to be included in its data for transmitting content material to the client station 132. For example, the defined macrodiversity region may be a Multicast Broadcast Service (MBS) region of a FDMa data frame such as, for example, an OFDMA data frame according to one of IEEE 802.16e.

Typical: table: voice control layer mode, group 310 Including non-delivery agreements, so it does not contain the payload of other agreements. Although the diagram is shown in Figure 3, it may not exist at present. It is defined as being directed to the dialog control layer module 31 and since the presently described embodiments are described as being related to a broadcast system' and thus do not need to be maintained at the client station 132, a 23 200930112 mutual state In one embodiment, the convergence layer module 312 provides its pipeline for one of the upper layer protocols/applications, and transmits its data through a media access control (MAC) layer module 314 as discussed further below. In other words, the convergence layer module 312 defines a protocol, an interface, an encapsulation, and a mapping to conform to and interface to the upper layer. In one embodiment, the convergence layer module 3 12 implements a handheld digital video broadcasting (DVB-Η). The Transport Stream Convergence Protocol (TSCP) is used to efficiently map DVB-H MPEG-2 transport stream packets for transmission as MAC service data units ( SDU (service data unit). The MAC layer module 3 14 on the transmitting side (for example, in the macro-division area control module 150) includes a scheduler that can receive the entity from which the data is filled. (PHY) configured upper layer MAC Service Data Unit (SDU). The MAC layer module 314 can also define a burst configuration that determines the configuration of an array of OFDMA frames given the size of the macro-diversity region of a data frame. The size of the data burst (including: 0FDMA size) and location within the diversity area. The MAC layer module 314 may also include a MAC protocol data unit (PDU) for processing its physical layer 316. Send the agreement. In one embodiment, the MAC layer module 314 includes a shared messaging MAC protocol that transmits (at a BTS) or receives (at a client station) a shared messaging control PDU. In a BTS, the shared messaging MAC protocol maps the sharing of the control control PDU (such as the macro diversity area MAP, and the MAC management PDU) to the physical layer 316 channel. The MAC layer module 3 14 also includes a traffic 24 200930112 channel MAC protocol, which places and fetches the MAC PDU to and from the physical layer 316 channel. In an embodiment in which the WiMAX is used, the MAC layer module 314 can include a MAC Common Part Sublayer (MCPS) according to one of the IEEE 802.16 specifications. The hierarchical model of FIG. 3 includes a MAC control layer module. Group 3 18. The MAC Control Layer Module 3 18 is an air link established between a BTS and a client station. The MAC Control Layer Module 318 can in turn manage an overall state machine that determines one of the states of the macro-diversity area airlink. The MAC Control Layer Module 3 1 8 also manages network initialization. Furthermore, the MAC Control Layer Module 3 18 is responsible for establishing and transmitting management messages, such as, for example, identifying one of the MAC data management messages that are included in the macro-diversity region of a data frame. A further description of the example management message for the content data of the macrodiversity region of the content material identified in the macrodiversity region is set forth below. In Figure 3, the physical layer 316 provides solid layer transmissions for airlink messages' such as, for example, waveforms formed on the transmitting side to transmit content material or waveforms received from one of the receiving sides to reconstruct the PDU. As described above, in one embodiment, the BTS can broadcast a MAC management message to the client station to identify the content material that it incorporates into the macro-diversity region. In one embodiment, the MAC management message may be a Service Identity Information - Advertise (SII-ADV) MAC management message, such as described in IEEE 802.16e. Furthermore, in one embodiment, a type/length/value element can be incorporated into the SII-ADV message 'a broadcaster that can be used to carry content material for the macro-diversity (or broadcast) area included in the data frame. Line identifier (CID) information. In addition, 25 200930112 TLV may include information about services available to the macro-diversity region, as will be discussed in more detail below. The MAC management message can be periodic broadcast without request 'or, for example, a client station can request the message to be sent. The following Table 1 shows its example SII-ADV message according to one of IEEE 802.16e. An example of this can be used as a MAC management message to identify content material to a client station. ❹

--------- Block length Remarks Management message Type 8-bit Set to a value of 68 according to the IEEE 802.16e standard. NSP List TLV Bits If present, this series is associated with the NSP that provides the ASP for the content material corresponding to the particular broadcast CID. This TLV includes a 24-bit NSP identification for each of the associated NSPs. NSP Change Count TLV 1 Byte If present, this series presents the NSP list that was previously published for the NSP List TLV. For example, each time the NSP changes, it increments by 1 (modulo 256). Broadcast Service Release TLV 4*n Bytes This series presents its broadcast services for use in the Giant Diversity area. This TLV system can be presented to each SII-ADV message by a BTS. Each broadcast service tag contains a 16 竺 broadcast CID and a 16-bit broadcast type. As shown in the example of Table 1, the SII-ADV management message includes multiple fields. The first field, called the management message type, uses the MAC management message that identifies the type of the message at 26 200930112. In this example, the value is set to 68 to identify the message as a SII-ADV message. According to IEEE 802.16e. The second field of the SII-ADV message in this example is called the "Network Monthly Service Provider (NSP) List TLV", and this example is an option. If it exists, This field series out its NSP associated with the ASP providing the content material. For example, as described above, in one embodiment, a particular ASP system can be connected to multiple broadcast service networks, each being a different NSP. The operation is used to broadcast content data to the client station via one or more ASNs. In this example, the NSP table column TLV field includes a 24-bit NSP identification for identifying its association with each ASP. Each NSP. As such, the size of this field depends on the number of associated NSPs (ie, this field size is the length of three bytes for the number of NSPs). Furthermore, the combination of ASP and NSP functions For a single service provider embodiment, this field The system may not be included. The third block of the SII-ADV message for this example is called the “NSP Change Count TLV.” This block is an option and may not always exist in some embodiments. The bit system is only the number of changes in the NSP table column TLV and is incremented by 1 each time the NSP table column TLV is changed. In one embodiment, if present, the NSP change count TLV system length is one byte and each When the NSP list is changed, it is incremented by 1 (modulo 256). The fourth block of the SII-ADV message is called “Broadcast Service Release TLV.” In this example, this TLV series can be used for a frame. In the present example, a broadcast service release TLV may be incorporated into the SII-ADV message for each of the broadcast services available to the macro-diversity region for 27 200930112. In this embodiment, each broadcast service The publishing tlV system includes a 2-bit long broadcast CID and a 2-byte broadcast service type identifier 'for a 4-byte multiplied by the total length of the number of available services. FIG. 4 is a diagram illustrating a broadcast service release TLV ( Also known as a broadcast suit An example of a tag. As shown in Figure 4, a broadcast service tag 402 can include, for example, two sixteen (16) bit blocks 404 and 406. The first block 404 is a broadcast service CID block. Bit, which includes

The broadcast CID of the broadcast service. The second field, 4〇6, is a broadcast service type field. In one embodiment, the broadcast service type of block 406 includes two sub-slots, namely an encoded profile block 408 and a service set block 410. The code setting play block 4〇8 includes #information about the coded material characteristics of the service. For example, the encoding provides information about the associated broadcast service, such as: the encoded version (G WMAV, etc.), the encoding rate, the frame rate, and the resolution of its content material for the broadcast service. The resolution can be the type of client device that is used by the client station to identify the service that it can access. For example, some users, such as mobile phones, or PMs, may be services that are not capable of accessing __specific resolutions, and resolutions. The user equipment system may be capable of accessing the special broadcast service 41G including television broadcast stations whose identification is available for the macro diversity area (such as: broad such as: inclusion (such as .ABC, or NBC). For example, service 28 200930112 And the block block 410 can include an identifier that identifies each of the available content channels (eg, an encoded text item). In yet another embodiment, the service set broadcast block 410 includes its identification Information about the individual pieces of the macro-diversity area (such as, for example, the evening news of ABC). In other embodiments, the combination of information identifying the services may be utilized. In yet another embodiment, the broadcast service type is blocked. The 6-series can be used to store = which corresponds to one of the specific broadcast service types. The special profile number can be used to identify the type of channel coding it uses for the broadcast service (for example: The specific resolution coffee (7), ..... is included in the channel of the broadcast service (for example: CNN, Fox news, ESPN, etc.). That is, for example, a set slot number is Can = two A group of channels, which are coded by coffee and have a low profile, are not displayed on the mobile phone. A different profile number can be used to identify the channel of the same group (4) for higher resolution. Displayed in the 'again-different numbering system can be used to identify a channel with a specific resolution amp& different groups, or so on. Or, for example, in: use the - encoding to set the rights field and One of the two fields of the implementation of a service profile block or both can be utilized - the profile field to identify the nature of a particular subset of pin services (eg, coded version, and available content channels, respectively). A client station can decode - telling information from the message and ... huge points: domain information 'and based on the - the set of fields is not interested in the content of the gossip (ϊ / in the content of interest) The client station can decode the macro domain and apply the included macro diversity map to receive the desired content material from the macro diversity area 29 200930112. If it is determined that there is no interested broadcast service, or no The client station can be solved The broadcast service, the customer, ignores and does not decode the macro-diversity area. In this way, the client ^ can ^ 'Beiyuan. In an embodiment, the client station determines whether there is interest in the macro-diversity area. The content data, by broadcasting the broadcast CIID of the broadcast service mark of the received sn• class message, if the money (10) matches a broadcast CID stored by the ( station (for example, the client station subscribes to the storage CID) The broadcast service identified by the broadcast CID), the client station can decode the huge diversity area and extract the content data of interest to the client station. - In another embodiment, even if the broadcast CID system does not correspond to the client station - With the broadcast service, the client station can verify the type of parking service of the broadcast service to: determine whether the macro-diversity area includes the content of the interest of the client station, and the coding scheme and resolution supported by the client station. == For example, 'If the client station expects to receive (10) and the customer receives a broadcast service that includes a broadcast service for the client station, the client can verify the broadcast service and: see 2 40 6 to see if CNN is included in the macro-diversity regional solution, whether it supports the coding code used to encode the simplified channel, and the content of the second is existing and uses the area of the coding scheme supported by " In this embodiment, the client station may display a question to ask the "& content information of the self-broadcast service and if the user 30 200930112, select (4) the content of the data before the user of the macro-diversity is informed. For the use of (4) (4) (if it exists in the embodiment, if the user chooses to extract the content data, a MAc and the information message can be sent from the client station and include the client information, which can be forwarded to the ASP For billing purposes. It should be noted that the second is only an example of how the client station applies to the broadcast service tag 4〇2 to determine whether to decode and extract content data from the giant diversity zone. Figure 5 is a flow diagram of one embodiment of establishing a management message to identify content material available for a macro-diversity region of a data frame. For illustrative purposes, FIG. 5 is described with respect to a management message that is a sn_ADV „fL information including a broadcast service tag, such as the figure shown in FIG. The flow begins at block 5.2, wherein a BTS 130 receives a service profile of a broadcast service that is provided in a macro-diversity region of a data frame transmitted by the BTS 130. For example, The service profile of the broadcast service may include a broadcast CID for the broadcast service, a coding pattern and a solution for encoding the content material, a service type (such as a broadcast television service, or a pay-view service), and identification thereof. Information about a particular service, such as: a particular television broadcast station provided in one of the broadcast services. In yet another embodiment, the service profile may include information identifying the individual pieces of content in the macro-division area, such as: one of the broadcasts being specific TV show. Further, as described above, in one embodiment, the broadcast service type may be a service profile number that can be found by a client station in one of the tables. Identification to identify the content of the channels and information about the encoding scheme and resolution used to encode the content material. Thus, in this example, BTS 130 31

This broadcast service is indeed; t. At block 51G'w, it is determined that there are no additional services to publish for inclusion in the macro-diversity region, and the flow continues to block 512. The block 512 'BTS 13G system combines the broadcast service to release the old SII-ADV message' such as the one described above with respect to Table 1. As noted above, the service profile received by 200930112 may include the broadcast CIE> and the service profile number for the broadcast service. This service setting file can be provided, for example, by Asp 160. For example, ASP 160 can utilize a management messaging scheme to communicate its management information including one of the service profiles to, for example, ASN gateway 120, which is then assigned. The service profile is to bts 13 for an embodiment, and the management message can be provided by the ASP 16 to its inclusion in an element manager (not shown) of the ASN 105, which in turn provides the management message to the ASN. The gateway 120, or for example, directly to the BTS 13 (or, for example, in an embodiment where only one broadcast service is included in the macro-diversity region defined by the macro-diversity region control module 15A, service profile) The system may be stored by the ASN gateway 12〇 or the BTS 130, such as, for example, during the installation and supply of the ASN gateway 12〇 or the BTS 13〇, respectively, and the flow is continued to block 504, where One of the bts 13 MAC MAC Control Layer modules establishes a broadcast service tag, such as the one described above with respect to Figure 4. At block 51, the MAC Control Layer module is then determined by the Giant Diversity Region Control Module 150. Is there any more The broadcast service is included in the giant diversity area provided to the BTS 13. If there is an additional broadcast service, the process continues to block 5〇2 and the service profile is for a broadcast service that is included under the giant diversity area. And extracting or obtaining, as described above. Next, a new broadcast service tag 4〇2 is directed to 32 200930112. In one embodiment, the macro-diversity region control module 15 defines a macro-diversity region that includes the content material. And providing the defined macro-diversity area to bts 130 for inclusion in the BTS 130-accumulated data frame. The establishment of the macro-diversity area and the provision of the macro-diversity area to the BTS 130 can be established with the BTS 13 as the SII-ADV. The message is simultaneously performed. Next, at block 516, the BTS 13 can combine the data frame developed by the BTS 13 into the client station 132, such as the data frame 2〇2 of Fig. 2. As described above, In an embodiment, the SII_ADV message is a mac management © message. Thus, in one embodiment, the SII-ADV message is sent by the BTS 13〇 to the downlink data area 236 under the data frame 202 and the content data is included in the information. The macro-diversity region 24 of the bin 202. Further, as described above, the BTS 130 can utilize different modulation and coding schemes to transmit different regions of the frame 2〇2. For example, in one embodiment, the BTS 13〇 The QpsK can be used to transmit the downlink region 236 and the BTS 130 can utilize the 64 QAM to transmit the macro diversity region 240. Again, in one embodiment, each of the bts 130 uses the same modulation and coding scheme to transmit simultaneously. Giant diversity area. However, the BTS 130 can each utilize different modulation and coding schemes to transmit its respective downlink link regions 236 that are included in the frames sent by the various BTSs 130. As described above, in one embodiment, the BTS 13 system can periodically broadcast SII-ADV messages. For example, the BTS 130 can periodically broadcast SII_ADV messages to the client station 133, such as for example, in each box, every other box, every fourth box, and the like, for broadcast by the BTS 130. Furthermore, if the BTS 130 receives a new or modified service profile after the SII-ADV message is established and transmitted, the process may return to block 502 and create a new broadcast service release. Tlv or modify an existing broadcast service to publish a TLV. At block 518, the data frame broadcast by the BTS 130 is then received by a client station 132, which decodes the downlink data area.

Field 236 and extracts the SII-ADV message. At block 520, the client station 132 then determines if the SII-ADV message indicates that the macro-diversity area 24 of the block 202 is content that includes interest to the client station 132. The client station 132 can determine this by extracting the broadcast service tag 4〇2 from the SII-ADV message and checking it to see if there is a broadcast service tag 4〇2 that includes one of the broadcast CIDs, the broadcast CID system It is identified that it includes one of the content of interest to the client station 132. Further, client #132 can also verify the broadcast service type block 406 to determine if the content of interest is available for the macro diversity area 240 and is encoded for a manner supported by the client station 132. For example, if a client station 2 subscribes to a broadcast service that is recognized by a specific broadcast CID, and the user of the client station 132 wants to watch a specific channel (eg, CNN), the client platform 32 The CID can be checked first in the sn_ mine to see if it includes the money CID for the broadcast service subscribed to the client station. If so, the client station can then verify the broadcast service pattern & 406 to determine if the broadcast content includes the desired channel and whether the desired channel is encoded in a manner supported by the client station. For example, if the client's mobile phone 'may only be able to decode and display the content data encoded by mpeg and having low resolution. Or, for example, in another embodiment, a broadcast CID system may be 34 200930112 Ο

It is used by systems that identify the broadcast service as well as the specific broadcast content and the code used. Alternatively, in yet another embodiment, the client station 132 may first look for one of the SII-ADV messages to broadcast a CID that corresponds to one of the client stations' subscription services. However, while the client station 132 is in any second SII-ADV interest and the broadcast CID is not found, the client station 132 can then compile the broadcast service type booth to determine whether the macro-diversity area is included or not. The client station 132 is interested in the content and determines whether the content material is encoded in a manner supported by the client station 132. If so, the client station 132 can extract, decode, and provide the desired content material to the user. Moreover, in this example, the client station 132 can query the client station 132 for the purpose of extracting and decoding the content material and the cost to the user (if any) before decoding the content material. Moreover, if the user decides to receive the content material, the customer 纟 132 can send a billing message indicating that the decision is sent to the BTS 13 〇, so that the information system for the client Η] can be forwarded to the ASp 16Q for The user is properly billed. * The client σ 132 confirms that the macro-diversity area 24 includes the user: the content of interest - the client station can then decode the macro-diversity area 240 and provide the content material to the user, in the box 522. As described above, the macro-diversity region 240 can utilize a different modulation "= code scheme than one of the downlinks 236. However, if the client station 132 determines that the macro-diversity region 240 is interested in the client station 132 The content of the client station 132 is returned to the block ^8 and continues to verify the received SII-ADV message to find a BTS 13〇 of the macro-diversity region 24 of the desired content of the client σ. About Establishing a Broadcast Service Tag and SII-ADV Message 35 200930112 • BTS 130 *Discussion 'In other embodiments, such a real system may be established by different elements. For example, in one embodiment, the macro-diversity area control module 150 or The ASP 160 system may be responsible for establishing such entities and providing them to the BTS Π 0 for transmission by the BTS 13 于 to the downlink region of the data frame. Figure 6 is a block diagram illustrating a simplified embodiment of a BTS. For the purpose of explanation, FIG. 6 will be discussed with respect to the above-mentioned figure i. The BTS 130 system may include a first interface 6〇2, a controller 6〇4, a storage device 606, and a transceiver 6〇8. And an antenna 61. The interface 6〇2 may include hardware and/or software for receiving content material such as, for example, a macrodiversity region defined by the macrodiversity region control module 150 and by Asp 16〇 A service profile is provided. The transceiver 6 8 can include hardware and/or software for transmitting and/or receiving data such as, for example, MAC management messages, content material, etc. For example, as above The 'utilization based on: In one embodiment of an OFDMA frame of 8〇2.16e, the transceiver 6〇8 is operable to transmit the downlink area and the macro diversity area of the frame and receive the uplink φ path area. The antenna 610 can be, for example, of any type. Antennas, such as: those commercially available. For example, the controller 604 can include one or more processors configured to generate MAC management messages, such as, for example, including a broadcast service bar tag 402. The SII-ADV message described above, such as the one described above with respect to Figure 4. The controller 604 can be further configured to create a data frame comprising a downlink area and a macro diversity area, such as: The macrodiversity region 24〇 and the map 242 discussed above. The generated mac management messages (including: SII-ADV messages described above) may be placed in the downlink area by the controller 6〇4 36 200930112 for transmission to the client station 132. The controller 604 can further configure the synchronous transmission of the macro-diversity region of the BTS 13 to enable the macro-diversity region transmitted by the BTS 130 of the network 100 to use a common modulation and coding scheme by the BTS. 13〇 is sent synchronously, as described above. Furthermore, as described above, the downlink areas transmitted by the various BTSs 130 of the network 100 can be transmitted using different modulation and coding schemes. The φ reservoir 606 can include a volatile and/or non-electrical reservoir. For example, in one embodiment, the storage device 6 6 may include: or a non-electrical storage device such as, for example, read-only memory (ROM, read oniy mem〇ry), non-electrical NVRAM (non-volatile random access memory), etc.; and one or more power-based storage devices such as, for example, random access memory (RAM, rand〇m access mem〇ry ). The memory 6〇6 can be used to store information such as used by the controller 604 to create a data frame. For example, φ § 'in one embodiment' wherein the 'macro-diversity area control module 150 is only used to transmit content material belonging to one broadcast service, and the storage unit 6 6 can store its broadcast CID for the broadcast service. And, for example, identifying the information that it uses to encode the encoded version of the content material, and identifying the information that belongs to the particular content channel of the broadcast service. As described above, in one example, the information identifying the code used can be a profile number that a client can look up in a table to determine the encoding protocol being used and other information about how the content material is encoded (eg, Resolution of content data). Similarly, the information stored by the storage device may include a client station that can be found in the macro-diversity region of the receiving data frame, which is stored in the table. The special (four) capacity channel. 'And again, in one example, Gan Shangan thinks that the giant diversity area is used to capture the content of the content that belongs to multiple broadcast services, and the controller 604 can be used to receive and process the connection. Makeup comes from a singular message such as ASP (which provides a broadcast service). For example, the old version, Jinben η. ° Back to Figure 1, ASP 160 can provide: including the management information of the broadcast cm for the content information provided and the information of the encoded content of the content and its identification by the broadcast provided by asp (10) Information about the specific content of the service network 115. Controller 604 can then store this information in storage 606 and utilize the received information to generate management messages that are identified by the content material contained in the macro-diversity area. Figure 7 is a block diagram showing one embodiment of a portion of a client station. As shown in the example of FIG. 7, the subscriber station 7 includes a receiver 7〇2, a processor 7〇5'a user interface 71〇, and an output device 7(10). The presentation device 708 can be, for example, any device capable of presenting content material to the user, such as, for example, a liquid crystal display (LCD), a high definition television (HDTV) n, and the like. The user interface 71() can include any device that can allow the client station 700 to receive information from the user, such as, for example, a key pad, a keyboard, a mouse, a touch screen, a microphone, and the like. The 〇 reservoir 712 can comprise any combination of electrical/non-electrical storage (e.g., RAM, ROM, etc.). The storage 712 can be used to store content that is of interest to the client station 700, such as, for example, a broadcast CID of a broadcast service subscribed to by the client station, and specific content material that the user desires to receive (eg, CNN, ESPN, etc.) This force (see, for example, what type of encoding the client station can decode, and the resolution or other parameters of the presentation device 708).

In one embodiment, the user can use the user interface 710 to provide information about the content of interest to the user, which is then stored by the controller 706 in the storage 712. For example, in an implementation ❹ φ / 八 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显 显The user system can then select the particular content that the user is interested in using the user interface 710, and the controller then stores it in the storage 712. For example, the user can be loaded via the user interface 710. §" The user wants to receive information about a particular sports channel. The controller 706 is detachable and then stores this information in the storage 712. Or, for example, in one embodiment, wherein: the client station has 700 transmitters to allow two-way communication, and the user interface 710 is used: the user system can be connected via a network (such as: a Lancome network) ) and pass: Subscribe to the broadcast service provided by the tear. The ASP system can then send the C1D for the broadcast service, along with any decryption information, for example, if the broadcast cake is encrypted by Asp to the station 700. Controller 706 can be coupled to 712. The information received in the storage receiver 7〇2 may include, for example, an antenna and hardware and/or software for receiving the transmission from the BTS (four) material and/or the soft invitation ' ^ « gg 7Λ< ^ receiving the communication The data is sent to a processor 705. The processor 7G5 may be responsible for decoding the signals it receives from the module (10) of the -BTS and forwarding the decoded signal 39 200930112 (e.g., content material) to a presentation device 7〇8. Handling a controller that is responsible for the management of the client station 700

Management, and so on. For example, when the MAC is provided for operation, when the client station 700 receives the decoder module 704 from one of the bts, the decoder module 704 recognizes and locates the resource frame. The decoder grip group 704 is followed by decoding at least part of the received data. For example, referring back to the data frame of the example of FIG. 2, the decoder module 704 can decode the preamble 208, the FCH 210, the DL mapping ττ ping 212, the UL mapping 214, and the downlink data region 236. The controller 706 can then analyze the decoded data and identify any mac management messages for the downlink data area of the client station 700. As mentioned above, and refer back to the table! In contrast to FIG. 4, in one embodiment, the SII ADV message core (which has a value of $68 for a management message type paste) can be utilized by the system to send its macro-diversity region 240 identified to the data frame 2〇2. Information on the content of the content. The controller 7〇6 (when analyzing the received MAC management message) can determine by analyzing the management message type field that the received message is for one of the client stations 7 SII_ADv message. The controller 706 can then extract the broadcast service tag 402 from the sn_ADV message and check the information it contains to determine if the macro location area 240 is content that the client station 7 is interested in. For example, the controller 706 can extract its stored information about the content of interest from the storage 712 and compare the information with the information received by the broadcast service tag 402. As described above, in one embodiment, the storage 712 can store the broadcast CID β of the content that is of interest to the client station in the instance, and control 200930112
