ABSTRACT:
A transmitting device includes a first buffer for temporarily storing audio data, a second buffer for temporarily storing video data, a multiplexing unit for outputting audio data coming from the first buffer and video data coming from the second buffer onto a single signal channel, and a transmission buffer monitoring unit for monitoring the amount of first buffered data stored in the first buffer and, if the amount of the first buffered data exceeds a first threshold, instructing the second buffer to discard video data.
