3.1.1.1.1.1.1.1.1JCTVC-D021 USNB Contribution: Response to WG11 resolution 10.1.3 of the 94th meeting [A. G. Tescher for USNB of WG11]
In response to WG11 resolution 10.1.3 of the 94th WG11 meeting, the USNB of WG11 responded as follows:
The USNB of WG11 responds affirmatively that it does expect "screen content" to be prevalent in the use of HEVC.
USNB of WG11 suggested considering the category of such "screen content" to include animation/rendered video content as well as the examples mentioned in resolution 10.1.3 of the 94th WG11 meeting.
USNB of WG11 requested WG11 to collect representative content.
USNBof WG11 indicated that it believes that it would be valuable to study the subject and characterize the behavior of the draft standard on such content, and that the behavior of the draft HEVC design on such content should be considered in the technical work.
3.1.1.1.1.1.1.1.2JCTVC-D028 JNB comments on WG11 Resolution 10.1.3: Coding of screen content [JNB of WG11]
JNB of WG 11 requested to clarify the necessity of the standardization of the screen content coding as a part of HEVC.
JNB of WG 11 indicated that most of such coding technologies are expected to be effective only for screen content and not to be used for the other HEVC applications, and recommended to do it as another part of MPEG standards rather than as a part of HEVC.
JNB of WG 11 requested to clarify the requirements on the coding of screen content.
JNB of WG 11 indicated that 4:4:4 colour format is supposed to be necessary for such a content, and recommended to consider the screen content together with 4:4:4 colour format for the future extension of HEVC.
JNB of WG 11 requested to solve the following concerns if and when the JCT-VC decided to add the coding of screen content into the HEVC requirements:
JNB of WG 11 requested that HEVC standardization time line should be kept as agreed in Guangzhou ('12/02 CD, '12/07 DIS, '13/01 FDIS)
JNB of WG 11 requested that the complexity of HEVC should not be unnecessarily increased by the adoption of coding tools which are effective only for the screen content.
