Description
Technical field
The present invention relates to the data processing field of Digital Television, particularly, is that a kind of Digital Television is play method and the device recorded.
Background technology
Along with development and the application of digital TV Broadcasting Techniques, Digital Television has entered huge numbers of families, as all extensive use digital TV Broadcasting Techniques such as handheld mobile television, in-car TV and family's TV.Digital television techniques can be play and record the signal of Digital Television, and plays and the work of recording can be carried out simultaneously.Data television signal is play and recorded all needs to receive transport stream (transport stream) bag, but because the transport stream packets of external transmission includes video packets, audio pack, captions bag etc., different types of transport stream packets is used different identification code (PID, Packet Identifier) identify, therefore Digital Television broadcasting record device need to use transport stream controller (transport stream controller) to filter transport stream packets, by the video packets in transport stream packets, audio pack, captions bag etc. filters out, to various bags are decoded and are play or record.
The structured flowchart that existing Digital Television is play the device of recording as shown in Figure 1, it comprises a playing module 11, records module 12 and two transport stream controllers 13,17, transport stream controller 13 only receives the transport stream packets that playing module 11 sends, and transport stream controller 17 only receives and records the transport stream packets that module 12 sends.
In transport stream controller 13, be provided with multiple filters 14,15,16 ..., each filter 14,15,16 is for receiving the transport stream packets with designated identification code, and the transport stream packets that different filters receives has different identification codes often.In the time that Digital Television is carried out play operation, playing module 11 sends instruction to transport stream controller 13, require transport stream controller 13 to receive the transport stream packets with designated identification code, transport stream controller 13 will distribute a fixing filter, as filter 14, for receiving the transport stream packets of this designated identification code.
Transport stream controller 13 receives the outside transport stream packets sending, and as from router or modulator-demodulator etc. receive transport stream packets, sends it in the filter that can receive this transport stream packets according to the identification code of transport stream packets.A certain filter as referred to herein can receive a certain transport stream packets, refers to that a certain filter is assigned with the identification code of the transport stream packets that the identification code of received transport stream packets receives with transport stream controller 13 identical.For example, the transport stream packets that the designated reception identification code of filter 11 is PID1, if the identification code of the transport stream packets that transport stream controller 13 receives is PID1, filter 11 can receive this transport stream packets.If the identification code of the transport stream packets that transport stream controller 13 receives is PID2, filter 11 can not receive this transport stream packets.
Transport stream controller 13 separates the transport stream packets with different identification code by different filters, thereby by video packets, audio pack, captions bag etc. separately, realizes the filtration to transport stream packets.
Because the broadcasting of Digital Television is very high to time requirement, require transport stream controller 13 to complete at short notice the filtration work of transport stream packets, therefore transport stream controller 13 receives after transport stream packets, need to filter at once, and the data after filtering are sent to playing module 11 in time.
In the same manner, in transport stream controller 17, be also provided with multiple filters 18,19,20 ..., each filter 18,19,20 is for receiving the transport stream packets with designated identification code.In the time recording the data of Digital Television, transport stream controller 17 receives the outside transport stream packets sending, and according to the identification code of transport stream packets, transport stream packets is sent to different filters 18,19,20 etc., and by filter 18,19,20 etc., the video packets of appointment, audio pack, captions bag etc. are filtered out, then the data after filtering are sent to and record module 12.When recording Digital Television, wish to reduce the indegree of writing to memory device as far as possible, therefore, record module 12 and do not require that transport stream controller 17 is sent to the data after filtering to record module 12 in time, but after stream controller 17 to be transmitted accumulates certain data volume, a large amount of data are sent in the lump and are recorded in module 12.
Because transport stream controller 13 is identical with the structure of transport stream controller 17, the operation principle of filter is also identical, if playing module 11 with record module 12 and share simply a transport stream controller, be playing module 11 and record module 12 and all receive transport stream packets from same transport stream controller, if playing module 11 with record module 12 and all need to receive the transport stream packets with same identification code from transport stream controller, the transport stream packets with same identification code is sent to same filter by transport stream controller, but filter cannot be differentiated received transport stream packets and need to send to playing module 11 and still record module 12, cause playing module 11 will receive less a part of data with one that records in module 12, the work that impact is play or recorded, can not realize and play simultaneously and record.
Therefore, based on above-mentioned situation, existing Digital Television is play record device need to arrange two transport stream controllers that work alone 13,17, meets respectively and plays and the requirement of recording, and causes the production of Digital Television broadcasting record device higher.And two transport stream controllers 13,17 work alone respectively, also cause Digital Television to play record device power larger, the electric energy of consumption is more, is unfavorable for saving the energy.

Embodiment
Digital Television of the present invention is play record device and can be applied in handheld mobile television, in-car TV and family's TV, can also be applied in the electronic equipment of other Applied Digital tv broadcasting technologies.
Referring to Fig. 2, Digital Television of the present invention is play record device and is had playing module 21, records module 22 and transport stream controller 23, playing module 21 can receive entrained data the processing of decoding of audio video transmission stream bag that transport stream controller 23 is inputted, therefore, playing module 21 is for broadcasting that the packet of Digital Television is decoded.
Record module 22 and be stored as file for the entrained data of audio video transmission stream bag that transport stream controller 23 is inputted, record module 22 and receive data, store data in the large buffering area, inside of oneself, then writing in files piecemeal, write efficiency improved thus.Therefore, record module 22 for data television signal is recorded.
In transport stream controller 23, be provided with multiple filters that work alone 30,40,50 ... each filter 30,40,50 is all set the identification code of the transport stream packets of its reception, transport stream controller 23 receives after transport stream packets, by the identification code of this transport stream packets, send in the buffer of corresponding filter, in this way the video packets in transport stream packets, audio pack, captions bag etc. are carried out to filtration treatment.In transport stream controller 23, be also provided with driver module 60, in driver module 60, be provided with filter and choose module 61, tunnel administration module 62 and filter closing module 63.
The present invention adopts hardware virtual technology, according to the need of work of filter, sets up tunnel on filter.As shown in Figure 2, transport stream controller 23 is set up four tunnels on filter 30, is respectively tunnel 31,32,33,34.The hardware virtual technology of setting up tunnel employing is conventional hardware virtual technology, the Chinese invention patent application that existing hardware virtual technology can be CN101751285A with reference to publication number.Certainly, the present invention can also adopt other hardware virtual technology.
Tunnel 31,32,33,34 is not fixing existence, but transport stream controller 23 is according to need of work, on filter 30, set up, only have transport stream controller 23 to receive playing module 21 or record after the instruction that module 22 sends, just can on a certain filter, set up tunnel.When filter 30 is during in idle condition, it does not have corresponding tunnel.After filter 30 filters transport stream packets, transport stream controller 23 is according to playing module 21 or record the instruction that module 22 is sent, cancel the tunnel of no longer working, and after the tunnel of filter association is all cancelled, close filter, filter enters idle condition, now on filter, there is no tunnel.
Playing module 21 or record module 22 and need to receive while having the transport stream packets of a certain designated identification code, sends instruction to transport stream controller 23, and this instruction is that instruction transport stream controller 23 receives the transport stream packets with designated identification code.Transport stream controller 23 receives after instruction, will distribute a filter for receiving the transport stream packets with designated identification code.
The tunnel administration module 62 of driver module 60 manages the tunnel of setting up, and comprises the mapping relations of setting up tunnel and filter.For example, transport stream controller 23 receives playing module 21 or records after the instruction of module 22, need on filter 30, set up tunnel, if filter 30 is in idle condition, do not set up any tunnel, now driver module 62 is set up a tunnel on filter 30, as tunnel 31.The tunnel 31 of setting up will receive by playing module 21 or record the pointer function that module 22 sends, and uses this pointer function function pointed to process the data of transport stream packets.
Tunnel 31,32 all can be stored in the transport stream packets of the buffer 35 of filter 30 and process, different tunnels uses respectively pointer function function pointed separately to process same transport stream packets, and a transport stream packets can be processed by multiple tunnels.When transport stream packets processing due to tunnel, can only read the data of transport stream packets, can not rewrite the data of transport stream packets, therefore multiple tunnels are processed same transport stream packets, can't affect the data integrity of transport stream packets.
Processing about tunnel to transport stream packets, for the data that send to playing module 21, is transport stream packets to be removed to packet header be reassembled as PES bag, then removes the remaining data in packet header of PES bag.For sending to the data of recording module 22 to be left intact.Tunnel reads the buffer data in corresponding filter, then transport stream packets is processed, data after treatment are put into from playing module 21 or are recorded the buffering area that module 22 applications come, can not rewrite the buffer data of filter, thereby the buffer data of guarantee filter is pure.
Because the tunnel of setting up on same filter can be many, therefore driver module 60, according to the real work needs of filter, is set up the tunnel more than on same filter.Different tunnels receives respectively different transport stream packets.
Tunnel administration module 62 is set up the mapping relations between tunnel and filter, and distributes to the unique mark of each tunnel, for identifying each tunnel.
In filter 30, be provided with a buffer 35, the transport stream packets receiving for stored filter device 30.Filter 30 receives after transport stream packets, can not notify tunnel 31,32,33,34 to process it, but the data volume of storing at buffer 35 is while exceeding threshold value, just can notification filter 31,32,33,34 process.Tunnel 31,32,33,34 is sent to data after treatment playing module 21 or records module 22.
The structure of filter 40,50 and operation principle and filter 30, all there is buffer 45,55, and driver module 60 can be set up many tunnels on filter 40,50, as set up tunnel 41,42,43 on filter 40, on filter 50, set up tunnel 51,52 etc.
Foundation, work and the closing process of tunnel are described below in conjunction with Fig. 3, Fig. 4 and Fig. 5.
Referring to Fig. 3, first transport stream controller 23 judges whether to receive by playing module 21 or records the instruction that module 22 sends, and this instruction is to receive the transport stream packets with designated identification code, performs step S1.The identification code of the transport stream packets that transport stream controller 23 receives can be arbitrary value.
Then, the filter of driver module 60 is chosen module 61 and is performed step S2, and the identification code of the transport stream packets that the filter that judges whether to work has received is identical with the identification code of the transport stream packets that received command request receives.Suppose that now filter 30 is in running order, only set up a tunnel 31 thereon, the identification code of the transport stream packets that tunnel 31 receives is PID1.Now, it is identical with the new identification code that receives the transport stream packets that command request receives that filter is chosen transport stream packets that tunnel 31 that module 61 judges filter 30 receives, therefore perform step S3, on filter 30, set up a new tunnel, as tunnel 32.
Tunnel administration module 62 manages newly-established tunnel 32, comprises the mapping relations of setting up tunnel 32 and filter 30, and tunnel 32, corresponding to filter 30, namely performs step S7.Meanwhile, tunnel administration module 62 also distributes unique mark of tunnel 32, for identifying tunnel 32.Finally, tunnel administration module 62 performs step S8, and the mark of tunnel 32 is back to playing module 21 or records module 22.
The identification code of supposing the transmission package that the tunnel 31 of filter 30 received is PID2, instead of PID1, and does not have other filter in running order.In this case, in step S2, filter is chosen module 61 and is judged that the identification code of the transport stream packets that the filter of not working received is identical with the transport stream packets identification code of the new required reception of instruction receiving, execution step S4, chooses an idle filter, as filter 40, and activate filter 40, on filter 40, set up a new tunnel, as tunnel 41, perform step S5.
Then, tunnel administration module 62 is set up the mapping relations of tunnel 41 and filter 40, gives tunnel 41 unique mark, performs step S6.Finally, the identification code of tunnel 41 is back to playing module 21 or records module 22, playing module 21 or record module 22 and will obtain data from tunnel 41.
Like this, as long as playing module 21 requires the identification code of the transport stream packets receiving to require the identification code of the transport stream packets receiving identical with recording module 22, these transport stream packets can be received by same filter, then are processed respectively by different tunnels.Due to separate work between different tunnels, the data that therefore playing module 21 receives from tunnel with record the data that module receives from tunnel and can not influence each other, can save like this quantity of filter.
For example, playing module 21 with record module 22 and all need to receive the transport stream packets that identification code is PID1, and all send instruction to transport stream controller 23, transport stream controller 23 will be set up two tunnels 31,32 on filter 30, tunnel 31 is for sending data to playing module 21, and tunnel 32 is for sending data to recording module 22.Then, the mark of tunnel 31 is sent to playing module 21 by transport stream controller 23, and the mark of tunnel 32 is sent to and records module 22.
Filter receives after transport stream packets, and transport stream packets is stored in self buffer.For example, the transport stream packets that filter 30 receives is all stored in the buffer 35 of filter 30.
Referring to Fig. 4, transport stream controller receives after transport stream packets, judge the identification code of transport stream packets, and check do not have in running order filter need to receive the transport stream packets of this identification code, if have, transport stream packets is sent in corresponding filter, and filter is stored in the transport stream packets of reception in buffer, performs step S11.Certainly, need to receive the transport stream packets of this identification code if transport stream controller does not find that there is filter, this transport stream packets be lost.
Then, filter execution step S12, judge whether the data volume that self buffer 35 is stored is greater than threshold value, if be not greater than threshold value, continue to wait for, otherwise execution step S13, notify seriatim 31,32 pairs of data of tunnel to process, each tunnel is processed data, and data after treatment are sent to playing module or record module, namely copy to playing module 21 or record the buffering area of module 22 inside, perform step S14.In step S15, filter 30 judges whether to have notified tunnel or not, if having, continues to notify uninformed tunnel.
If all tunnels are all notified complete, filter performs step S16, removes the data after filtering.
Playing module 21 or record module 22 and receive after the data of sending, plays or records processing.If stop playing or recording, can send the instruction of closing tunnel to transport stream controller 23.For example, playing module 21 sends the instruction of closing tunnel 31 to transport stream controller 23.
Referring to Fig. 5, transport stream controller 23 judges whether to receive the instruction of cutting out tunnel, perform step S21, if receive instruction, perform step S22 by tunnel closing module 63, the mapping relations of cancelling filter 30 and tunnel 31, then perform step S23, judge whether filter 30 does not cancel the tunnel of mapping relations in addition.If filter 30 has not had other tunnels of having set up mapping relations, perform step S24, close filter 30, filter 30 enters idle condition, on filter 30, there is no tunnel.If in step S23, filter closing module 63 judges the tunnel 32 of not cancelling in addition mapping relations on filter 30, does not close filter.
From above-mentioned scheme, playing module 21 with record the required transport stream packets of module 22 and can on same transport stream controller 23, carry out data processing, the different virtual passage of the same filter in transport stream controller 23 can be respectively to playing module 21 with record module 22 and send data, make playing module 21 and record the data that module 22 receives and be independent of each other mutually, guarantee to play and record independently carrying out of work.
Because the broadcasting record device of Digital Television only arranges a transport stream controller, save a set of hardware device, thereby reduced the production cost of Digital Television broadcasting record device, also reduce needed power, reduce the consumption of electric energy.
Certainly, above-described embodiment is only preferably execution mode of the present invention, when practical application, can also there is more change, for example, the quantity that is based upon the tunnel on each filter is limited, the quantity maximum that limits the tunnel of each filter foundation is four; Or, to choose different filters the transport stream packets with same identification code is filtered, such change also can realize object of the present invention.
Finally it is emphasized that and the invention is not restricted to above-mentioned execution mode, also should be included in the protection range of the claims in the present invention as set up the variations such as the change of tunnel quantity on the change of number of filters, each filter.
