Abstract:
1. An apparatus comprising: an encoder configured to generate a format encoded data stream in response to an input signal, wherein said format encoded data stream (i) has a first size, and (ii) comprises a plurality of recording units each having a uniform size; a packet generator configured to (i) generate special packets from extracts of said format encoded data stream, and (ii) reinsert said special packets into said recording units of said format encoded data stream in a previously unused portion of said recording units, wherein (a) said recording units retain said uniform size within said format encoded data stream after said special packets are reinserted, and (b) the reinsertion of said special packets does not increase said first size of said format encoded data stream; a disc loader configured to write said format encoded data stream with said special packets on a disc, wherein said special packets are contained within said recording units; and a rebuild circuit configured to (i) rebuild one or more navigation files and a file system with said special packets and (ii) write said one or more navigation files and said file system to said disc, wherein writing said format encoded data stream with said special packets contained within said format encoded data stream, said navigation files and said file system occupies the same space on said disc as a conventional system recording said format encoded data stream, said navigation files, and said file system.
