A 'bag of bits'. For example, if a single Version is available in high and low quality files, each is a different Encoding. A Location at which an Encoding (and therefore a Program) is available. A description of access restrictions that apply to a Location. A program brand. Commonly called a show (in American English). A group of Episodes. The same as po:Brand. owl:sameAs po:Episode A version of an Episode. Every copy of the same Version has the same frames. For example, each Episode of the Brand 'Planet Earth' has a U.S. version (narrated by Sigourney Weaver), and a British version (narrated by David Attenborough). Each episode is correctly modelled in URIplay with a separate U.S. and British Version. A separate Version should also be defined for a cut of an Episode that has been edited to remove potentially objectionable content. This class is the same as po:Version. A time and channel at which a Version is/was receivable. This Class is the same as po:Broadcast.
