All in the topic: what are "progams" in context of video?

As you may expect, any google lookup containg "programs" yield many irrelevant results... no matter search tricks you can apply.

I tried some general search about video metadata, found a glossary about digital & multimedia, and also a search engine about metadata but didnt get anything.

In the ffprobe doc it seems to be sort of the container, but what is its use?

thanks for any reply which lift this fog ^^

MPEG Transport Streams (.ts) are used to carry television content over satellite or cable systems..etc. A transport stream may contain multiple channels in it. For each channel, there will be a video stream, one or more audio streams, zero or more subtitle streams, and possibly other data streams. All streams associated with a particular channel is organized into a 'program'.
