Title:
オーディオビデオ同期の単方向無効化の技術
Document Type and Number:
Japanese Patent JP5102347
Kind Code:
B2
Abstract:
This disclosure describes techniques to allow for unidirectional disabling of audio-video synchronization. In particular, a synchronization command is defined for packet-based network protocols. The synchronization command can disable audio-video synchronization in a sending direction, a receiving direction, or both the sending and receiving direction. In this way, devices are given more control over audio-video synchronization, and can disable such synchronization in a unidirectional manner only, while maintaining synchronization in the opposite direction.
