-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Here's a crack at some definitions. I suspect there will be a few minor variations on this, as these may be a little ATSC-centric. But having these in place will help us all speak the same language at least. If you have comments on these definitions, or have other terms to add, lets do it here first, then we can publish the results to the W3C site in a little more beautiful form. Program - a collection of related video, audio and/or data in a single "file". This is also generically called "content". Program Stream - as defined in ISO 13818-1 for MPEG - a streaming version of a Program. Transport (Stream) - as defined by ISO 13818-1 for MPEG - a multiplexed collection of concatenated Program Streams without beginning or end. Content Author - usually a studio (Disney, ABC Studios) that creates video, audio, and "data" or some aggregation of these. Channel - a Program Stream. This is also known in DVB as a "service". Network - company that authors and aggregates content and distributes it (ABC). Transport Company - a company that aggregates and emits (usually in cable or satellite) a collection of channels (DIRECTV). This is also sometimes referred to as a "network", but usually confuses folks when it is. Broadcaster - company that emits radio waves (KABC). Affiliate - broadcaster (KABC) that gets most of its content from a network, and thus has an affiliation to that network (ABC). Feed - the serialized stream of content from a network. -----BEGIN PGP SIGNATURE----- Version: PGP for Personal Privacy 5.0 Charset: noconv iQA/AwUBN8vm7Cl9dIG/haQGEQI6kACfeXW5ftBAF1pbFKPDKjQPZ4kF7k0An2Wp UMBk74FkziwjTy1mfNbaynf1 =jKr/ -----END PGP SIGNATURE----- ------------------------------------------------------ Michael A.
