pps_extension_type_flag index

Reported by: Vadim Owned by: jlchen
Priority: minor Milestone: Draft 5
Component: SHVC text and test model Version: Draft 4 version 3
Keywords: Cc: jlchen, yanye, jillboyce, jct-vc@…

Description

For MV-HEVC/SHVC, the index of pps_extension_type_flag should be 1 instead of 0 marked with bold below.

pps_extension_flag
if( pps_extension_flag ) {

for ( i = 0; i < 8; i++ )

pps_extension_type_flag[ i ]

if( pps_extension_type_flag[ 0 ] )

poc_reset_info_present_flag

if( pps_extension_type_flag[ 7 ] )

while( more_rbsp_data( ) )

pps_extension_data_flag

}

Also, it might be better to align the flag naming across MV-HEVC/SHVC and RExt extensions. Currently, it is pps_extension_flag and pps_extension_type_flag in MV-HEVC/SHVC, and pps_extension_present_flag and pps_extension_flag in RExt, respectively.
