163 A physical Ogg bitstream consists of multiple logical bitstreams
165 from multiple logical bitstreams multiplexed at the page level. The
166 logical bitstreams are identified by a unique serial number in the
177 content or encoder of the logical bitstream it represents. Pages of
178 all logical bitstreams are concurrently interleaved, but they need

181 original logical bitstreams from the physical bitstream by taking the

188 logical bitstream in a physical Ogg bitstream starts with a special

204 secondary header packets after the bos page for logical bitstreams
205 and these must also precede any data packets in any logical
208 So, a physical bitstream begins with the bos pages of all logical
213 The encapsulation specification for one or more logical bitstreams is
220 per logical bitstream. The Ogg Vorbis bos page starts with the byte

247 bos pages, eos pages for the logical bitstreams need not all occur

254 In chaining, complete logical bitstreams are concatenated. The
255 bitstreams do not overlap, i.e., the eos page of a given logical
