detailed description

In order to make the technical solutions of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings, which are only a part of the embodiments of the present disclosure, but not all embodiments. In the case of no conflict, the following examples The technical features in the embodiments can be arbitrarily combined with each other.

Adding the function of TS (Transport Stream) to IP (Internet Protocol) in the existing set-top box, the function is to convert the TS stream of the TV program into an IP packet, and the mobile terminal passes the router. After discovering the shared resources of the set-top box, you can watch live programs, and also provide recording programs and playback functions.

Before describing this embodiment, the generation process of the TS stream and the signal processing flow of the existing set top box will be introduced. Referring to FIG. 1 , the digital television program signal is mainly transmitted by TS stream. After the program is completed, the video signal, the audio signal, and the auxiliary data are respectively subjected to analog-to-digital conversion, and then respectively compression-encoded. There are many different ways to compress the code here, such as the common MPEG (Moving Picture Experts Group) 2, MPEG4, H.264, H.265, and so on. The data stream ES (Elementary Streams, original audio stream and audio stream) output from the encoder is converted into a PES packet by a PES (Packetized Elementary Streams) packet, and then packaged into a TS stream. The multiplexer synthesizes a multi-channel single program or multi-program TS stream into a 1-way multi-program TS stream. Therefore, there are many sets of audio and video information of the program in the TS stream received by the front end of the set top box. The TS stream is modulated into a high frequency signal and transmitted.

The process of processing the TS stream by the set top box is as shown in FIG. 2. The high frequency signal received by the set top box is demodulated into an intermediate frequency signal by a high frequency head, and then digitally demodulated by a demodulator to obtain the TS stream. Then demultiplexing, respectively decoding the audio and video, then performing digital to analog conversion (DAC, Digital to analog converter), and finally outputting the AV (Audio and Video abbreviation) signal playback. If you need to see the descrambling program, you need to add the descrambling function to the demultiplexer.

Embodiment 1

As shown in FIG. 3, the system for program resource sharing processing provided by the embodiment of the present disclosure includes a set top box 1, a router 2, and a client 3. The set top box 1 and the client 3 are connected to the same router 2 through a wireless network or a Lan (local area network) to form a shared local area network. The sharing protocol may be a DLNA (DIGITAL LIVING NETWORK ALLIANCE) protocol, an Airplay protocol or a proprietary protocol. Such a set top box 1 and a client 3 Wireless data interaction is possible. Install the corresponding APP (Application) on the client 3, open the APP to find the shared resource of the set top box 1, and connect with the shared resource through the router 2 to share the program resource of the set top box 1. The client 3 generates a corresponding program request instruction according to the first operation of the user, and sends it to the set top box 1 through the router 2. The set top box 1 retrieves the TS stream corresponding to the TV station program according to the program request instruction and packs it into an IP packet, and sends the IP packet to the client 3 through the router 2 for parsing and playing.

The client 3 can be a plurality of mobile terminals, such as a mobile phone, a tablet computer, a computer, and the like. A set top box 1 can communicate with multiple mobile terminals simultaneously. In this way, the user can receive and watch the live broadcast program on the television through a mobile terminal, and different mobile terminals can select to receive programs of different satellites and different frequency points, for example, the mobile phone can receive the live broadcast program of the central 5 of the Zhongxing 6B. The tablet can receive live broadcasts from Shanghai Star of Zhongxing 6B. The prior art is limited by the bandwidth of the network through the iQiyi on the mobile phone, and the live program of the embodiment of the present disclosure is a conventional DVB signal, which is transmitted coaxially and is fast. After the set-top box converts the received TS stream into an IP packet, it can be directly transmitted to the client for playback, and the live broadcast speed is not limited by the network bandwidth. Moreover, a plurality of mobile terminals can simultaneously watch different live programs through the set top box, and the mobile terminal and the set top box do not affect each other. For example, if you watch the central unit on the TV set, you can watch the central unit 2 on the mobile phone. You can watch the live broadcast programs of the central unit on the tablet. The TV, mobile phone and tablet can be viewed simultaneously without affecting each other.

Embodiment 2

Based on the foregoing embodiment 1, the client can also control the set top box to perform program recording and recorded program playback. The client 3 generates a corresponding program recording instruction according to the second operation of the user, and sends it to the set top box 1 through the router 2. The set top box 1 performs instant recording or scheduled recording according to the program recording instruction. The program recording instructions include a start command, a program channel, and a recording time. Start the recording by starting the command. After the user selects a certain program channel, if the recording time is not input, it means that the current program content of the program channel input by the recording system is input; if the recording time is input, the recording of the program content is started when the recording time is reached. When the top The box 1 responds to the program recording command and feeds back the response result and transmits it to the client 3 through the router 2. The result of the response indicates that the set-top box has received the program recording instruction and explicitly needs to record it immediately or schedule it.

The recorded program content is stored in the set top box. When the user needs to watch, the client 3 generates a corresponding viewing playback instruction according to the third operation of the user, and sends it to the set top box 1 through the router 2. The set top box 1 generates a recorded program list according to the viewing playback command, and sends it to the client for display through the router 2. The user clicks on a certain program name on the recorded program list, that is, generates a program playback instruction for playing the program, and sends it to the set top box 1 through the router 2. The set top box 1 finds the TS stream corresponding to the program according to the program playback instruction and packs it into an IP packet, and sends the IP packet to the client 3 through the router 2 for parsing and playing. The set-top box recording (PVR, Personal video recorder) function, the built-in hard disk (memory) can store recorded high-definition movies and the like, and the mobile phone can be directly viewed after being connected, without paying or being affected by the home network.

Referring to FIG. 4, in the system of the first embodiment, the set top box of the program resource sharing process includes a plurality of high frequency heads 10, a plurality of demodulators 20, a plurality of demultiplexers 30, and a TS stream encoder. 40. Packing module 50 and network module 60. Network module 60 can be a LAN (Local Area Network) module or a WIFI module. A plurality of high frequency signals (from different satellites or different types of program sources) received by the cable are analogically demodulated into a plurality of intermediate frequency signals by corresponding high frequency heads 10, and a plurality of intermediate frequency signals are digitally demodulated by the demodulator 20 to obtain corresponding ones. TS stream. A number of demultiplexers 30 filter the corresponding TS streams to completely resolve the audio stream and the video stream (equivalent to the audio stream only TS stream). The audio stream and the video stream are respectively transmitted to the audio decoder and the video decoder for decoding, and then the digital analog signal is converted and outputted, and the AV signal is played, which is a manner of broadcasting the existing television program, which will not be described in detail herein.

When a mobile terminal needs to broadcast a certain television program, a plurality of high-frequency heads 10 perform frequency-locking according to program information (a CPU (Central Processing Unit) in the set-top box is parsed according to a program request command), and the corresponding response tuner Extracting the intermediate frequency signal of the frequency point required for the program information (that is, the program information has only one tuner response, and the signal of the corresponding frequency point extracted by the tuner is the content that the user needs to watch), and the response The demodulator corresponding to the tuner performs digital demodulation to obtain a TS stream, and the demultiplexer corresponding to the demodulator filters the TS stream to stream the audio stream and the video stream (equivalent to the TS stream only for audio and video) Completely parsed out. The TS stream encoder 40 acquires and encodes the filtered TS stream (only the audio stream and the video stream) from the corresponding demultiplexer, and transmits the encoded TS stream to the packing module 50 for packing, and outputs the IP packet. The network module 60 sends to the router 2, which is transmitted by the router 2 to the client 3 for playback.

Based on the current digital TV front-end program signal in China, the TS stream is usually used as a carrier for transmission. The TS stream is a kind of data stream based on the MEPG2 protocol developed by ITU-T (International Telecommunications Union Telecommunication Standardization Organization). It is mainly used for errors. environment of. Since the TS stream in the current device is first subjected to 8B/10B encoding, and then a preset control character is added, the serial transmission is performed in the ASI system at a code rate of 270 Mbit/s. When the packaging module 50 is packaged, the serial input TS stream is first decoded by 8B/10B, and then serially converted to parallel output. When performing TS stream extraction, a system reference clock is provided by the CPU's crystal (27 MHz) to perform 8B/10B decoding of the data, and a parallel TS stream with a clock is generated.

Since the TS stream is used as a real-time transport stream, the TS stream transmission error is not repeated in the ISO/IEC 13818 protocol, and the transmission rate of the program is as high as 4 Mbit/s even in the case of no multiplexing. Therefore, the TCP (Transmission Control Protocol) protocol cannot be used when the TS stream that is output in parallel is converted into an IP packet. The UDP (User Datagram Protocol) protocol is required as the transport layer, so that the real-time performance of the TS stream and the efficiency of transmission can be ensured. The packetization standard of the TS stream is 188 bytes or 204 bytes, and the IP protocol stipulates that one maximum IP packet is 1500 bytes. Considering that the UDP header and the IP header occupy part of the space, in this embodiment, one IP packet encapsulates several TS packets. According to the OSI layer 7 protocol, when the IP packet is transmitted, the physical layer and the data link layer and the control protocol layer are also required, that is, the set top box is transmitted through the set network module.

Referring to FIG. 5, in the system of the second embodiment, the set top box of the program resource sharing process further includes a recorder 70 and a memory 80 based on the first embodiment, and the recorder 70 performs the program recording instruction according to the program. Instant recording or scheduled recording. The recorder 70 responds to the program recording command and feeds back the response result and sends it to the router through the network module 60. 2. Router 2 sends the response to client 3. The program content recorded by the recorder 70 is stored in the memory 80.

If the memory 80 receives the viewing playback command, the recorded program list is generated according to the stored program content, and is sequentially sent to the client for display through the network module and the router 2. When receiving the program playback instruction, the memory 80 finds the TS stream corresponding to the program content and packages it into an IP packet through the packaging module 50. The packaging module 50 sends the IP packet to the router 2 through the network module 60, and the router 2 sends the packet to the client 3. Analyze playback.

If the set-top box wants to receive programs of different satellites at the same time and receive different types of program sources, it is necessary to set different types of high-frequency heads, such as high-frequency heads with satellite signals, high-frequency heads of cable television cables, and ground. Receive the high frequency head of the signal, etc. Since the set top box needs to support the request of processing multiple clients at the same time, the set top box needs to lock multiple frequency points simultaneously (ie, determine the frequency of the live program), and filter and descramble the multiple TS streams. A demodulator 20 and a demultiplexer 30 are required for each tuner. In this way, multiple client live broadcast and recording requests can be processed in the background without affecting the live program viewing function of the set top box itself.

In the embodiment of the present disclosure, the program resource sharing process between the set top box 1 and the client 3 mainly includes three aspects: live program sharing, remote recording, and recorded program sharing. After the client 3 opens the APP, the above three options pop up, and the corresponding option can be selected to implement the corresponding function.

If the user selects live program sharing, all the TV stations are displayed on the APP, and clicking on a TV station generates a program request command for watching a live broadcast and sends it to the set top box through the router. The CPU in the set top box parses the program signal according to the program request command (that is, which television station, the frequency point of the television station is), the tuner 10 performs frequency locking according to the program information, and extracts the intermediate frequency signal corresponding to the frequency point (ie, finds out The program signal of the television station is digitally demodulated by the demodulator 20 to obtain a TS stream, and then the TS stream is filtered and descrambled by the demultiplexer 30 to obtain a TS stream containing only audio data and video data, and TS stream coding. The device 40 encodes the TS stream output by the demultiplexer 30 and transmits it to the packing module 50 for IP packing. The packing module 50 outputs the IP packet and sends it to the router 2 through the network module 60. The device 2 transmits to the client 3 for parsing and playing. This will only play the program content of the TV station.

If the user selects remote recording, the APP pops up the command setting box, inputs the start command, the program channel (which one to record) and the recording time to generate the program recording command; and sends it to the network module 60 in the set top box through the router. The network module 60 transmits the program recording command to the recorder 70 for parsing. The recorder 70 determines whether it is an instant recording or a scheduled recording according to the recording time. The recorder 70 responds to the program recording command and feeds back the response result and sends it to the router 2 through the network module 60. Router 2 then sends a response to client 3, notifying the client that the set-top box is recording or preparing for recording. The recording process is prior art (currently there is a program recording function) and will not be described in detail here.

If the user selects the recorded program sharing, the APP directly generates a viewing playback command and sends it to the set top box 1 through the router 2. Network module 60 transmits the view playback instructions to memory 80. The memory 80 generates a recorded program list according to the viewing playback command, and sequentially transmits it to the client 3 through the network module 60 and the router 2. The user clicks on a certain program name in the recorded program list to generate a program playback instruction for playing the program, and sequentially transmits it to the memory 80 through the router 2 and the network module 60. When receiving the program playback instruction, the memory 80 finds the TS stream corresponding to the program content and packages it into an IP packet through the packaging module 50. The packaging module 50 sends the IP packet to the network module 60 and the router 2 to the client 3 for parsing and playing.
