/ / VOD/AOD mail system combining e-mail and VOD/AOD and method thereof

摘要

The present invention relates to a video / audio mail device and method combining e-mail and video / on-demand audio (VOD / AOD), and registers video / audio files made of MPEG 1 and MPEG 2 to be transmitted to each server. By sending only the digest information (specific information) about the file to the counterpart, the receiving terminal needs a large amount of storage media, and wastes a large amount of transmission paths flowing through the digital network when receiving unnecessary video / audio mail. It has the advantage of solving the problem of wasted storage media / receiving time / play time due to downloading when receiving video / audio, so that MPEG audio can be received even by mail recipients who use lines that are smaller than the bandwidth of MPEG-1 video. The advantage is that you can receive both MPEG 1 video and MPEG 2 audio simultaneously. , There is an effect to provide a single interface that allows the transfer to freely selected regardless of the file is the MPEG 1, 2 (MPEG1, 2) to the video / audio file attached to the transmitting side that sends the message.
