-------------------------------------------------------------
This release has HVXC conformance tools which include encoded
bit streams and reference test signals. 

These tools are build according to the following section of
ISO/IEC14496-4.

5.5.13.6	Procedure to Test Decoder Conformance

Using these tools, you can build all verification program
and verify whether the conformance condition is satisfied
or not.

Moreover, if you build test decoded signals using VM-software
and verify test decoder conformance, file "scrp_conformace"
can be used by adjusting your machine environment(for detail, 
see "scrp_conformance").

HISTORY

    - 1999/06/09: initial version(preliminary, version 0.1)
    - 2000/01/28: add "segsnr" tool(to measure segmental SNR)
    - 2000/01/28: add "segsnr" tool(to measure segmental SNR)
    - 2000/10/20: remove bitstreams/reference signals in archive
