Dear experts,
When I am reading the trace file dumpped by the JM94 software,I am quite confused by the following decoding process:
@25654 mb_type 011 ( 2)
@25657 ref_idx_l0 1 ( 1)
@25658 ref_idx_l0 0 ( 0)
@25659 mvd_l0 1 ( 0)
@25660 mvd_l0 1 ( 0)
@25661 mvd_l0 011 ( -1)
@25664 mvd_l0 1 ( 0)
@25665 coded_block_pattern 1 ( 0)
For ref_idx_l0,which is coded as te(v),if bitstream is"1",the output syntax value is also "1". However,as in the standard,that's should be "0" instead.(We can refer to Gary Sullivan's previous email "In other words, the value 0 is coded as 1 and the value 1 is coded as 0").Is this a bug in JM software94? Would anybody be kind to make it clear to me?
Many thanks!!
Best regards,
XU Ke
