12. 12 Application(2) Structure of HVCT system Structure of HVCT system The system consists of three parts; encoding manager, network manager, decoding manager. The system consists of three parts; encoding manager, network manager, decoding manager. The encoding manager: The encoding manager: Process the multimedia data from video camera and microphone and encode the raw data to MPEG4/MP3.The encoded multimedia data is integrated to one stream through the A/V MUX and then passed to network manager. Process the multimedia data from video camera and microphone and encode the raw data to MPEG4/MP3.The encoded multimedia data is integrated to one stream through the A/V MUX and then passed to network manager. Network Manager: Network Manager: put the encoded data in the RTP payload and then send them to the designated destinations. put the encoded data in the RTP payload and then send them to the designated destinations. The decoding manager: The decoding manager: Decodes the received data depends on the media type, i.e. audio, video. Decodes the received data depends on the media type, i.e. audio, video.
