摘要： Video data is coded at either a minimum transfer rate or maximum transfer rate and stored in a storage unit as a video reply message. In a case where the video data has been coded at the minimum transfer rate and stored, the video reply message is transmitted upon being multiplexed with an audio reply message if the actual transfer rate agrees with the minimum transfer rate. If the two transfer rates are different, invalid bits conforming to the difference between the rates are generated and the invalid bits, the audio reply message and the video reply message are multiplexed and transmitted. In a case where the video data has been coded at the maximum transfer rate and stored, on the other hand, the video reply message is decoded when an incoming call arrives, the video data thus obtained is coded based upon the actual transfer rate, and the video reply message obtained by coding is multiplexed with the audio reply message and transmitted.
摘要翻译：视频数据以最小传输速率或最大传输速率进行编码，并作为视频应答消息存储在存储单元中。在视频数据已经以最小传送速率被编码并被存储的情况下，如果实际传输速率与最小传送速率一致，则在与音频应答消息多路复用时发送视频应答消息。如果两个传输速率不同，则产生符合速率差的无效比特，无效比特，音频应答消息和视频应答消息被复用和发送。另一方面，在视频数据已经以最大传输速率被编码并存储的情况下，当来电呼叫到达时视频应答消息被解码，这样得到的视频数据是根据实际传送速率进行编码的，通过编码获得的视频应答消息与音频应答消息多路复用并发送。

摘要： A system is disclosed for multiplexing, transmitting, and receiving picture data and sound data, wherein the picture data and sound data are balanced in a limited transmission capacity so as to obtain a better overall quality to effectively use the transmission ability of a medium. The content of at least one of the picture data and sound data are detected and used for control of the content of the transmission. The content of the transmission is controlled by changing data and sound to correct a difference between the processing speed of the picture data and the sound data, thereby improving the quality of a video conference system or the like where the transmission capacity is insufficient.
