Abstract
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.
