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.
Claims29
A method comprising the steps of:
- generating a command to disable synchronization of video information and audio information in only one direction of a bi-directional communication;
- sending the command to a device;
- sending first audio information and first video information to the device, wherein synchronization is disabled for the first audio information and the first video information;
- and
- receiving second audio information and second video information from the device, wherein synchronization is enabled for the second audio information and the second video information.
