- the method further includes: the information transceiving controller converting the graphic data in the content into an HTML format, and publishing the graphic data in the HTML format to the web server for information Terminal access.
- the media server transmits the format converted audio and video data in a broadcast or multicast manner.
- the media server further includes a streaming media server, and the streaming media server transmits the format converted audio and video data to the information terminal in a unicast manner.
- the method of audio and video transmission in the home range includes:
- Step 1 The media server parses the received CMMB signal to obtain program information (EPG/ESG), and converts the program information into an HTML page, and the HTML page is published on a web server embedded in the media server.
- EPG/ESG program information
- the HTML page contains program information (EPG/ESG) of each channel on the one hand, and playback parameters of audio and video data of these channels, such as audio format, video format, audio and video sample rate, time stamp information, etc.
- EPG/ESG program information
- playback parameters of audio and video data of these channels, such as audio format, video format, audio and video sample rate, time stamp information, etc.
- SDP Session Description Protocol
- the SDP file includes transmission parameters such as IP, User Datagram Protocol (UDP), RTP, and RTCP in addition to the description of the playback parameters.
- UDP User Datagram Protocol
- RTP User Datagram Protocol
- RTCP Transmission Paragram Protocol
- the program of one CCTV1 can be transmitted by using broadcast or multicast address parameters, so that multiple information terminals in the home range can receive it;
- the unicast address parameter transmission can be used, so that the information terminal can connect to the media server according to the standard of the streaming media server to receive the audio and video data of the program.
- the information terminal can obtain these SDP files by accessing a web server embedded in the media server.
- Step 2 The media server transmits the audio and video data of each program in the CMMB signal to the information terminal by using IP multicast or broadcast technology through WiFi.
- the transmission parameters of the audio and video data transmission of each program are consistent with the transmission information published on the HTML page in step 1, so that the information terminal can receive the corresponding data of the program according to the transmission parameters described in the SDP file.
- the media server In general, especially in the case of a large number of data sources, such as the media server not only receives the CMMB signal, but also receives signals from other sources such as IPTV, if the bandwidth of the WiFi is insufficient to simultaneously transmit all programs in a broadcast or multicast manner.
- the media server can embed the streaming server and transmit the audio and video data of the program through the streaming server in a unicast manner; another method is: sharing a set of transmission addresses by multiple programs For example, CCTV1 and CCTV2 share an IP broadcast or multicast address, but in fact the IP broadcast or multicast address only transmits one program.
- the method of audio and video transmission within the family range may also include:
- Step 3 The information terminal obtains program information in HTML format by accessing the web server embedded in the media server and displays it through its own browser. After the user selects to play a program such as CCTV1, the information terminal sends a control command for selecting CCTV1 to the Web server, as shown in FIG. Step 4: After the media server obtains the command of selecting CCTV1 through the embedded web server, if the audio and video data of CCTV1 has not been transmitted yet, the audio and video data of CCTV1 in the CMMB signal is converted into the RTP/RTCP encapsulation format, and then released according to The transmission parameters described in the SDP file of CCTV1 on the Web server are transmitted to the information terminal via WiFi.
- Step 5 After obtaining the SDP file of CCTV1 from the Web server, the information terminal receives the audio and video data of CCTV1 according to the transmission parameter of CCTV1 described in the SDP file, and plays the program of CCTV1 according to the playing parameters of CCTV1 described in the SDP file.
- the media server can receive the audio and video data of CCTV1 from different external content networks (such as digital television network, IPTV network or internet), and convert the format to the information terminal, and the information terminal You don't need to know the original source when playing the audio and video data.
- external content networks such as digital television network, IPTV network or internet
- the present invention maximizes the technologies supported by existing information terminals, including supporting WiFi access technology, browser technology, streaming media technology based on RTP/RTCP, and audio and video playback.
- the technology does not need to improve the information terminal, so the cost is relatively low.
- the present invention can facilitate the information terminal to seamlessly access the content provided by each content network within the family.
- the low-end mobile phones since the low-end mobile phones generally only support one-quarter universal intermediate format (QCIF), or one-quarter video image array (QVGA) resolution video, you can add transcoding to the home media server.
- the function ie: converts the audio and video data received from the content network into different video formats suitable for different information terminals, and then sends them to the corresponding information terminal. In this way, different information terminals can share the same audio and video data (but the video format is different), thereby realizing the "three screens in one" business function.
- QCIF universal intermediate format
- QVGA video image array
