source: 3DVCSoftware/branches/HTM-4.0.1-VSP-dev0/source/Lib/TLibDecoder/TDecEntropy.h @ 166

Last change on this file since 166 was 166, checked in by mitsubishi-htm, 12 years ago

Initial integration of VSP into HTM 4.0.1. The version used for JCT3V-B0102 at Shanghai meeting.

  • VC9 project/solution files updated. Other Visual C++ project/solution files are not updated.
  • Linux make file updated.

TODO

  • A second release is expected to include some bug fix and improvements on the interface, e.g. to move switches from macro definition to the configuration file.
  • A third release is expected after being integrated within HTM 5.x, which is to be used for CE1.h anchor.
  • Property svn:eol-style set to native
