Abstract

A data transmission system for cellular phones. A video data encoder encodes video data, and an audio data encoder encodes audio data. A video data storage unit stores encoded video data, and an audio data storage unit stores encoded audio data. A multiplexer multiplexes video data from the video data storage unit and audio data from the audio data storage unit. An audio signal detector measures the audio level of the inputted audio data and generates a data write control signal for controlling the video data encoder and the audio data encoder and an audio detected signal for controlling a multiplexing controller which generates a data read control signal for controlling the video data storage unit and the audio data storage unit and generates a data multiplexing control signal causing the multiplexer to output one of the video data, the audio data, and the multiplexed video and audio data.
