Abstract
An apparatus used to communicate with a plurality of audio/video (A/V) end nodes in an Audio Video Bridging (AVB) network. The apparatus may include a first A/V end node. The first A/V end node may be configured to transmit a clock reference stream including a plurality of timestamps to a plurality of A/V end nodes. The plurality of A/V end nodes may transmit a media stream including a plurality of video samples and a plurality of audio samples to one another. The media stream may be separate from the plurality of timestamps. The plurality of A/V end nodes may be arranged to syntonize or synchronize the plurality of video samples and the plurality of audio samples with one another for playback in response to the plurality of timestamps.
Claims23
An apparatus for communicating with a plurality of audio/video (A/V) end nodes in an Audio Video Bridging (AVB) network, the apparatus comprising:
- a first A/V end node configured to:
- transmit a clock reference stream including a plurality of timestamps to a plurality of A/V end nodes that transmit a media stream including a plurality of video samples and a plurality of audio samples to one another, the media stream being separate from the plurality of timestamps and each of the plurality of A/V end nodes being arranged to syntonize or synchronize the plurality of video samples and the plurality of audio samples with one another for playback in response to the plurality of timestamps.
A computer-program product embodied in a non-transitory computer readable medium that is programmed for communicating with a plurality of audio/video (A/V) end nodes in an Audio Video Bridging (AVB) network, the computer-program product comprising instructions to:
- transmit a clock reference stream including a plurality of timestamps to a plurality of A/V end nodes;
- and
- transmit, from the plurality of A/V end nodes, a media stream including a plurality of video samples and a plurality of audio samples to one another, the media stream being separate from the plurality of timestamps and each of the plurality of A/V end nodes being arranged to syntonize or synchronize the plurality of video samples and the plurality of audio samples with one another for playback in response to the plurality of timestamps.
An apparatus for communicating with a plurality of audio/video (A/V) end nodes in an Audio Video Bridging (AVB) network, the apparatus comprising:
- a plurality of first A/V end nodes, each including a first input to receive a media stream including a plurality of video samples and a plurality of audio samples from one another and a second input to receive a clock reference stream including a plurality of timestamps from a second A/V end node, the plurality of first end nodes being configured to syntonize or synchronize the plurality of video samples and the plurality of audio samples with one another for playback in response to the plurality of timestamps.
