发明名称 AUDIO AND VIDEO COMMUNICATION EQUIPMENT AND SYSTEM THEREFOR
摘要 PROBLEM TO BE SOLVED: To provide audio and video communication equipment and an audio and video communication system in which continuity of audio and video data is ensured even in the case of frequent occurrence of congestion in a LAN. SOLUTION: This system is provided with an image processing section 3 that applies analog/digital conversion to an image, an audio processing section 4 that applies analog/digital conversion to audio data, an image compression section 5 that obtains a compressed image signal, an audio compression section 6 that obtains a compressed audio signal, a multiplexer section 7 that multiplexes the compressed image signal and the compressed audio signal to convert the result into an audio/video multiplex signal, a LAN interface section 8 that outputs the audio/video multiplex signal to a LAN 9 and provides an output of a congestion generating signal on the occurrence of congestion on a LAN traffic and a data quantity control section 10 that controls a data quantity of the audio/video multiplex signal based on the congestion occurrence signal. The data quantity control section 10 controls the data quantity to reduce the audio/video multiplex signal when the congestion generating signal is outputted from the LAN interface section 8.
