#483 closed defect (fixed)

Redundant deblocking process in inner regions of I_PCM

Reported by: kchono Owned by: bbross
Priority: minor Milestone: D7
Component: Text Version: D6 (H1003) dI/dJ/dK
Keywords: Cc: bbross, wjhan, jct-vc@…

Description

In the draft text, inner regions of an I_PCM coding unit are subject to deblocking if its coding unit size is larger than (1<<Log2MaxTrafoSize). Even if the I_PCM inner regions are subject to deblocking, the samples are not affected since qPL results in 0. So the draft text is correct but redundant. It would be better to explicitly state that inner regions of I_PCM coding units are not subject to deblocking in 8.7.1.1 in order to avoid redundant processing.

Attachment is a suggested text that avoids the redundant processing.

By the way, it would be better to revise the incorrect inference of split_tranform_flag in 7.4.8, instead of 8.7.1.1.

If we revise 8.7.1.1, "20120412-kchono.doc" in attachments is a suggested text. Otherwise, if we revise the split_tranform_flag semantics, "20120412-kchono-alternative.doc" in attachments is a suggested text.
