Description

SAT-IP SERVER PROVIDED WITH POWER UTILIZATION ENHANCEMENT FUNCTION
The present invention relates to a Sat-IP server power management system reducing power consumption of a Sat-IP server device.
A large number of television and multimedia services being made available to consumers today, methods for enabling the host, i.e. an image display device such as a TV set with a digital receiver-decoder to satisfactorily process the received services are required. An image display device may receive programs via cable or satellite broadcasting in the form of separate subscription formats.
Sat-IP is an IP-based system distributing satellite broadcasts in an efficient manner. Sat-IP system provides transmission of satellite signals to multiple users. The satellite broadcasting is received by server devices and is directed to client devices with the Sat-IP internet protocol. The client devices send specific control messages to notify the server device with respect to the program of choice.
A transponder typically receives a television signal on the ground from satellite uplink stations and processes the signal by encoding, amplifying and rebroadcasting the same. Satellite receivers then transmit the same to a digital receiver of an end-user so that it is decoded and displayed on an image display device.
On the other hand, the Sat-IP server devices comprise a number of tuners and demodulators integrated thereinto to simultaneously serve several clients via concurrent channels and therefore eliminates the need for the RF tuner and demodulator in the client device, therefore acting as a common resource of the IP network and transferring satellite broadcasts to client devices.
Typically, after the demodulation, the transport stream is transferred to the client devices using an IP network such as for instance a wired Local Area Network (LAN) and the client devices present the incoming broadcast content to the users.
The Sat-IP protocol requires that the clients access to transport streams using RTSP or HTTP, upon which the respective transport streams are transferred through the IP network. Control messages for functioning of the system transferred through the IP network include commands such as “Play” by which the client devices transmit the broadcast parameters (frequency, polarization, video PID etc.) to server devices. While the “Setup” command serves for reserving the tuner, “Play” sets parameters and change channel and “Teardown” interrupts the connection between client and server devices. The “Options” command should be periodically transmitted from the client device in a period no greater than 30 seconds to inform the server that broadcast is received.
Among others, one of the prior art disclosures in the technical field of the present invention can be referred to as KR20120065602, which defines a method and apparatus for reducing the power consumption on a set-top box provided to shut-down power of an unused video tuner when playing a video using the set-top box. The method on the set-top box comprises the following steps: turning on the power of a client STB, and operating a normal operation; activating an MoCA link on the client STB for communicating with a server STB; receiving video data from the server STB when a video play request a transmitted to the client STB using the MoCA link and shutting down the power of a tuner when playing the provided video data on the client STB.
The present invention, on the other hand, provides a system and method by which a Sat-IP server is operable so as to automatically reduce power consumption of the Sat-IP server in an efficient manner as provided by the characterizing features defined in Claim 1.
Primary object of the present invention is to provide a system and method by which a Sat-IP server is operable to consume a substantially reduced amount of active power.
The present invention proposes a Sat-IP server device in the form of a satellite broadcast receiving and IP network based distribution system. The Sat-IP server is in signal connection with several Sat-IP clients to distribute requested transport streams in an IP network.
The invention additionally provides that a demodulation control module in the form of a software module provides that several demodulation blocks are individually selectively powered or power supply thereto is interrupted by a demod power assignment unit. In other words, the demodulation control module controls the demod power assignment unit and the latter applies a respective output voltage to the respective demodulation block.
The demodulation control module continually monitoring the communication between the Sat-IP server device and the Sat-IP client devices locates certain commands from the Sat-IP clients in the manner that if a “Play” command is received, the associated demodulation block is powered by the demod power assignment unit or if a “Teardown” command is in question, the associated demodulation block’s power is interrupted. Further, if an “Options” command is not timely transmitted from a respective Sat-IP client device, the demodulation control module again drives the demod power assignment unit to interrupt power supply to the associated demodulation block.
Accompanying drawings are given solely for the purpose of exemplifying a system and method by which a Sat-IP server is operable, whose advantages over prior art were outlined above and will be explained in brief hereinafter.
The drawings are not meant to delimit the scope of protection as identified in the claims nor should they be referred to alone in an effort to interpret the scope identified in the claims without recourse to the technical disclosure in the description of the present invention.
Fig. 1 demonstrates a general schematic view of the main components including the Sat-IP server and client devices.
Fig. 2 demonstrates the block diagram of a demodulation control module with other demodulation blocks as controlled by a demod power assignment unit according to the present invention.
Fig. 3 demonstrates a flow diagram of the controlling scheme involving the client devices interacting with the Sat-IP server device according to the present invention.
The present invention proposes a Sat-IP server as a satellite broadcast receiving and IP network based distribution system, receiving programs via satellite broadcasting for instance in the form of separate subscription formats.
Digital and interactive TV systems provide a comprehensive amount of TV channels and programs. A conventional structure receiving program contents receives a transport stream via a tuner. A set-top box or an image display device such as a TV set may typically contain a number of tuner inputs. The set-top box or the image display device may receive programs using built-in satellite tuners.
The Sat-IP server of the present invention has multiple tuners as well as demodulators suitable for receiving broadcast multimedia content tuning to signals of different generations (for instance DVB-S and DVB-S2).
The tuners are typically connected to dish antennas collecting satellite signals to be focused by the parabolic curvature thereof. Conventionally, signal received from a satellite dish is amplified by a low noise amplifier (LNA) and converted to IF signal (Intermediate frequency) in the form of a block of frequencies by a block converter (the LNB, low noise block downconverter), which can be then processed by the demodulators. The demodulators typically output transport streams to the Sat-IP server having an audio/video processing unit, which accordingly processes the transport streams and retrieves service data for all the channels. As is known to the skilled reader, the intermediate frequency is typically created by mixing the carrier signal with a local oscillator signal by heterodyning, which allows the signals in microwave frequencies to be sent over a length of cable. The output of the mixer is an IF signal of a specific bandwidth that can be amplified.
According to the present invention, the IP-server is provided with an electronic control unit which oversees operation of the server in terms of power allocation to different sub-units thereof, as will be delineated hereinafter.
According to the invention, the electronic control unit of the IP-server that is in signal communication with a plurality of Sat-IP clients communicates with a demodulation control module as demonstrated in Fig. 2. As is known to the skilled worker, the Sat-IP protocol requires that the clients access to transport streams using RTSP or HTTP, upon which the respective transport streams are transferred to Sat-IP clients through the IP network. Typically, control messages include commands such as “Play” by which a respective Sat-IP client device sets parameters (frequency, polarization, video PID etc.), for instance for changing channels. For reserving a respective tuner the “Setup” command is used and “Teardown” command serves for interrupting an active connection between client and server devices.
To this end, a demodulation control module of the invention provides that the demodulation blocks (demod block a, demod block b etc.) are selectively powered by a demod power assignment unit. The demodulation control module is a software module that controls the demod power assignment unit, which in turn transmits or interrupts power to the respective demodulation block. The demodulation control module therefore continually monitors Sat-IP client commands such as “Play” and “Teardown” from the Sat-IP clients and accordingly selectively controls the demod power assignment unit, which then applies the respective output voltage to the respective demodulation block. Accordingly, if a “Play” command is received, the associated demodulation block is powered by the demod power assignment unit or if a “Teardown” command is in question, the associated demodulation block’s power is interrupted.
It is to be noted that the “Options” command should be periodically transmitted from the client device in a period no greater than 30 seconds to inform the server that broadcast is received. Therefore, if this command is not timely received, the demodulation control module will drive the demod power assignment unit and the latter will again interrupt power supply to the associated demod block.
In summary, the present invention proposes a Sat-IP server device in the form of a satellite broadcast receiving and IP network based distribution system, the Sat-IP server receiving a plurality of broadcasting services and comprising a digital TV processor, a plurality of tuner and associated demodulation blocks.
In one embodiment of the present invention, the IP-server is in signal communication with a plurality of Sat-IP clients so as to transfer requested transport streams to a Sat-IP client through an IP network.
In a further embodiment of the present invention, a demodulation control module provides that a plurality of demodulation blocks is selectively powerable by a demod power assignment unit.
In a further embodiment of the present invention, the demodulation control module is a software module that controls the demod power assignment unit, which in turn transmits or interrupts power to a respective demod block.
In a further embodiment of the present invention, the demodulation control module continually monitors Sat-IP client commands from the Sat-IP clients and selectively controls the demod power assignment unit, which applies a respective output voltage to the respective demodulation block.
In a further embodiment of the present invention, if a “Play” command is received, the associated demodulation block is powered by the demod power assignment unit or if a “Teardown” command is in question, the associated demodulation block’s power is interrupted.
In a further embodiment of the present invention, if an “Options” command is not periodically transmitted from a respective Sat-IP client device in a period no greater than 30 seconds to the Sat-IP client server device, the demodulation control module drives the demod power assignment unit and the latter interrupts power supply to the associated demodulation block.
The present invention therefore provides a system and method by which a Sat-IP server is operable so as to automatically reduce power consumption of the Sat-IP server in an efficient manner by means of a demodulation control module in cooperation with a demod power assignment unit.
