Difference between channels and streams in AVTP? #847

Open Praveen-apur opened 6 years ago

Praveen-apur commented 6 years ago

Hello Everyone,

Can I know the difference between Streams and Channels in terms of AVTP?

Regards, Praveen.

At a high level, a stream encapsulates the data transmission between endpoints (a talker and one or more listeners). A stream contains channels, each of which is typically either a discrete data stream or a component of a multi-part (e.g. surround sound) data stream. Specifics are highly dependent on what sort of AVTP sub-protocol you are using.

Hi levi pearson,

For the comment : Specifics are highly dependent on what sort of AVTP sub-protocol you are using. Do you mean formats like mpeg2ts and h264 and .wav file formats Does all formats supports 8-channels?

Thanks in advance.

@Praveen-apur - I assume you have read IEEE1722 from here https://standards.ieee.org/standard/1722-2016.html ? Available formats support different numbers of channels.
