Primary Video Set

Primary Video Set in Advanced Content consists of Advanced VTS space, Standard VTS space, and VMG. Basically Advanced VTS is used only in Advanced Content, and Standard VTS may be used in Advanced Content even though this VTS is mainly used for Standard Content. In Advanced Content, VMG may exist in the Primary Video Set, however the transition to VMGM_DOM or FP_DOM is not allowed.

Advanced VTS

Advanced VTS is used for the Video Title Set for Advanced Content. Compared to Standard VTS, it supplies the following enhancements.

1) More enhancements for an EVOB

  • 1 Main Video stream
  • 8 Main Audio streams (max)
  • 1 Sub Video stream
  • 8 Sub Audio streams (max)
  • 32 Sub-picture streams (max)
  • 1 Advanced stream

2) Integration of the Enhanced VOB Set (EVOBS)

  • Integration of both Menu EVOBS and Title EVOBS

3) Elimination of a layered structure

  • No Title, no PGC, no PTT and no Cell
  • No support for Navigation Commands and UOP control

4) Introduction of new Time Map Information (TMAPI)

  • For a Contiguous Block, one TMAPI corresponds to one EVOB and it shall be stored as a file with the same base name as the EVOB.
  • For an Interleaved Block, the TMAPIs which correspond to EVOBs in the Block shall be stored as a file.
  • Some information in a NV_PCK is simplified.


Standard VTS

Standard VTS is normally used in Standard Content, however it may be used in Advanced Content via the TMAP structure. The EVOB information for Standard Content, such as HLI and PCI (button highlights, etc.) is ignored if the Standard VTS is used in Advanced Content.
