Adopt 5.1.5.1 (simplified pruning for use of MV of BL as candidates in EL figure 2b from JCTVC-M0124) as modification of TextureRL scheme in SHM (not WD).

Overall, the proposal looks like a good simplification to use if we do not want to instead apply some other change to obtain coding efficiency improvement.

M0188/ M0322/ M0425 (InterDigital, Qualcomm, Samsung)

(Noted under BoG report M0449) For the reference layer sample location derivation used in the resampling process, the BoG recommended the following: To adopt the method mentioned in section 2.2 of the BoG report, which is the method used in the current software, as proposed in JCTVC-M0188, JCTVC-M0322 and JCTVC-M0425 (not the entire proposals, but this element of them).

The allowed layer ID value for the AUD was discussed, and it was agreed that the value should correspond to the lowest VCL NAL unit layer ID in the AU.

|
M0274 (Qualcomm)
|
M0274 proposes to allow inter-layer referencing of the region of the reference layer outside of the conformance cropping window. (The current draft specifies the reference to be bounded by the cropping rectangle.) Adopted (option A in M0274). Software will be provided for both HEVC and AVC base layer operation by the proponents.

M0309 (Qualcomm)
|
M0309 sends offsets (in VPS) to specify the relative spatial alignment of the base & enhancement layers (without cropping the base layer). Regarding "region of interest scalability" – should the EL rectangle include regions without a corresponding base layer position? The prior SVC can do a (somewhat restricted) form of this. The entire BL region can be a subset of the EL region or the entire EL region can be a subset of the BL picture region. Adopt with that restricted form of "ROI" flexibility, but in SPS syntax rather than VPS (exact location left to editor discretion).

To move the direct dependency flag syntax section to directly follow the dimension_id syntax (ahead of profile/tier/level) signalling to enable access to the data without entropy decoding.

|
To change the syntax element output_layer_set_idx[ i ] to output_layer_set_idx_minus1[ i ] due to the following reasons:
* The syntax element layer_id_included_flag[ ][ ] used for output_layer_set_idx[ i ] equal to 0 is for layer set 0, while for layer set 0 layer_id_included_flag[ ][ ] is not defined in HEVC version 1.
* It is clear that the target output layer for layer set 0 is layer 0 (the base layer) anyway.

M0269/D0048 (Qualcomm)
|
It was asked if it makes sense to limit inter-layer prediction for particular picture to use only at most one inter-layer reference picture (for SHVC only). It was agreed that this restriction should only apply to cases where filtering is needed for each lower layer reference picture, e.g. spatial scalability.

Agreed to recommend adoption of all aspects but have a semantic constraint that inter_layer_idc[ i ] shall be increasing. Add an edito's note stating that further improvements related to aspect 3 are encouraged. Also agreed to let the editors to combine text of JCTVC-M0457, JCTVCC-M0458, and JCTVC-M0209.

Adopted, although needs editorial improvement. It was suggested to find an alternative term rather than using "delay". The editorial quality of the concept of being "decoded completely" and the concept of dependency was suggested to need improvement of clarity.

Adopt the proposed SEI message with the following change: the persistence scope of the SEI message should be further restricted to be within a CVS.
