CE8-related: SPS flag for BDPCM
Abstract
In the current design of the VVC specification and reference software, there is no High Level Syntax flag to activate BDPCM (unlike other Screen Content Coding tools). This contribution proposes to add a sps_bdpcm_enable_flag at SPS level. It is also proposed that this flag follows the behaviours of sps_ibc_enabled_flag for Common Testing Conditions. It is asserted that this proposal is a bugfix.
JVET-O0165 CE8-related: SPS flag for BDPCM [F. Henry (Orange)]
In the current design of the VVC specification and reference software, there is no High Level Syntax flag to activate BDPCM (unlike other Screen Content Coding tools). This contribution proposes to add a sps_bdpcm_enable_flag at SPS level. It is also proposed that this flag follows the behaviours of sps_ibc_enabled_flag for Common Testing Conditions.
The introduction of the SPS flag gives also BR reduction for natural content under CTC.
Obviously, introduction of a high-level flag was forgotten when BDPCM was adopted. Currently, it can only be disabled at block level.
JVET-O0376 method 1 has the same aspect.
