  • Video telephone system and terminal device therefor
    Patent number: 6850267
    Abstract: A terminal device stores in a nonvolatile memory a video encoding method, a size expressed by pixels, a frame rate, a bit rate, and a key frame insertion interval suitable for reception. A receiving side terminal device notifies information to a sending side terminal. According to the information, the sending side terminal device encodes video data obtained by shooting an object and transmits encoded video data. Also, the sending side terminal device cuts, from the video data, video data of a size not exceeding a least size among a size of the video data obtained by the sending side terminal device, a size expressed by pixels suitable for transmission in the sending side terminal device, and a size expressed by pixels suitable for reception in the reception side terminal device. The sending side terminal device encodes and transmits the video data.
