Abstract

本稿では デジタルビデオ(DV)カメラの高精細動画像を、IP網を介してリアルタイムに伝送することを目的としたプログラムの開発のための基礎検討結果を述べる.輻輳によるパケットロス対策としてDVデータの伝送レート変換アルゴリズムを、また無音検出による駒落としによる伝送遅延の短縮法を提案している.In this paper, our basic study results of a program, that was developed to transmit high quality video data from a digital video (DV) camera over IP Network in real time, are shown. We propose an algorithm to convert the DV data rate to be slow. It can be used when a packet-loss occurs due to the network congestion. Another algorithm, which can shorten the transmission delay-time, is also proposed. It is realized by dropping the DV frame when the voice is silent in the frame period.
