Example Embodiment
[0060] Embodiment 1: The conversion process of the media stream carried by the E1 signal of the CRBT service to the RTP data stream, see Image 6
[0061] Step S601: The signaling processing part of the media server receives the control message for playing audio CRBT / video CRBT from the application server;
[0062] Step S602: The media server reads the audio CRBT / video CRBT data through the file system;
[0063] Step S603: The media server is streamed into an RTP package (local track file), transcoded in the media server to G.711 (audio color ring back tone) format, audio and video multiplexed into H.223 (video color ring back tone) format, packaged and sent to E1 DSP of the processing unit;
[0064] Step S604: The DSP takes out the G.711 and H.223 data from the RTP packet under the control of the application server, removes the RTP header and IP header, and puts the load content into the designated E1 time slot and sends it to the CS domain;
[0065] Step S605: Determine whether the f...
Example Embodiment
[0067] Embodiment 2: The conversion process of the RTP data stream of the CRBT service to the media stream carried by the E1 signal, see Figure 7
[0068] Step S701: The signaling processing part of the media server receives the recorded audio CRBT / video CRBT control message from the application server;
[0069] Step S702: The media server opens the recording file;
[0070] Step S703: The DSP of the media server reads the corresponding E1 time slot data from the E1 interface;
[0071] Step S704: After the DSP caches the read data to a specified size, it adds the RTP header and the IP header to the media forwarding storage part (ie PS domain) of the media server;
[0072] Step S705: The media forwarding and storage part stores the audio CRBT / video CRBT as required, and this RTP media stream includes the G.711 (CRBT) format and the H.223 (Video CRBT) format;
[0073] Step S706: The application server determines whether to issue a stop recording command, if yes, execute step S707, if not, ...
