Digital sound recording method and media

摘要

Additional information of multi-programs can be recorded using a source pack which indicates channel numbers and the like in multi-channel or single-channel recording. An additional flag AF in this pack indicates whether the pack is auxiliary information which is constructed with a plurality of pack groups or auxiliary information which is constructed with a single pack. If AF is 0 and the total pack number (T.P. No.) is 0, the pack is a source pack of a single channel. If AF is 0 and T.P. No. is n ( NOTEQUAL 0), the T.P. No. is defined to indicate the source pack number. Also, if AF is 1 and T.P. No. is 0, the pack is the last pack; if AF is 1 and T.P. No. is n ( NOTEQUAL 0), the T.P. No. indicates the total number of packs appended to the pack. <IMAGE>
