Multimedia communication management device, has management unit applying transmission delay to audio data exchanged through telephonic link to compensate difference of transmission duration between audio data and video data

摘要

The device has a management unit (MG) commanding a connecting unit (ML) to establish a telephonic link (L1) between audio communication terminals (T1, T2) and applying a transmission delay to an audio data exchanged through the link (L1), when a multimedia communication establishment request is received. The delay partially compensates a difference of transmission duration between the audio data and a video data. The video data is exchanged by video communication terminals (PC1, PC2) through a multimedia link (L2) established within an asynchronous network.
