Previously-identified cases that may not yet be addressed







MV

motion vectors are random, maximum page DRAM misses / minimize cache hits
  (according to memory bandwidth model... e.g.  JCTVC-H007)

Broadcom or TI




Collocated ref idx

RIDX

Test collocated_ref_idx (single slice or multiple slice/picture with different reference lists.)

May already have this







HRD

bitstream with largest possible CPB removal delay (maximum number of coded bits per picture but within MinCR)










DBLK

deblocking and SAO control combinations with tiles and slices

We have some; more would be desirable










Maximum number of slices permitted for Profile & Level combination; Each slice has unique ref_pic_list_modification() and pred_weight_table() with maximum num_long_term_pics

C. Fogg










CTU size is 64x64 with no CU splits, and only one coded transform unit in the lower right 4x4 corner of the CTU with deltaQp signalled (as raised by P. Kaspenberg on the JCT reflector 12-Sept-2012)

C. Fogg










inferred splits along non-CTU both horizontally and vertically

We may already have this










various combinations of transform_skip_enabled_flag, transquant_bypass_enable_flag, cu_transquant_bypass_flag

M. Zhou, J. Xu










Additional features of POC signalling (combined with wrapping, leading pictures, sub-layer non-reference pictures)

A couple of bitstreams have been provided; more would be desirable

Video resolution







pic_width_in_luma_samples = pic_height_in_luma_samples = (1 << Log2MinCbSize), with various CTU sizes.

F. Bossen

It was noted that some bitstreams are not compatible with planned extensions.
