165 A physical Ogg bitstream consists of multiple logical bitstreams
167 from multiple logical bitstreams multiplexed at the page level. The
168 logical bitstreams are identified by a unique serial number in the
180 content or encoder of the logical bitstream it represents. Pages of
181 all logical bitstreams are concurrently interleaved, but they need
183 within the logical bitstream. Ogg demultiplexing reconstructs the
184 original logical bitstreams from the physical bitstream by taking the
186 the appropriate logical decoding entity.
189 logical bitstream only. Pages are of variable size and have a page
191 logical bitstream in a physical Ogg bitstream starts with a special
206 of that logical bitstream type. Ogg also allows but does not require
207 secondary header packets after the bos page for logical bitstreams
208 and these must also precede any data packets in any logical
211 So, a physical bitstream begins with the bos pages of all logical
216 The encapsulation specification for one or more logical bitstreams is
223 per logical bitstream. The Ogg Vorbis bos page starts with the byte
237 "Chaining"). Grouping defines how to interleave several logical
240 synchronised audio tracks using different codecs in different logical
245 In grouping, all bos pages of all logical bitstreams MUST appear
249 physical bitstream MUST begin with the bos page of the logical video
251 bos pages, eos pages for the logical bitstreams need not all occur
255 logical bitstream MUST have a unique serial number within the scope
258 In chaining, complete logical bitstreams are concatenated. The
259 bitstreams do not overlap, i.e., the eos page of a given logical
261 chained logical bitstream MUST have a unique serial number within the
