Proposed FEC Timestamp for HRBM

Sunghee Hwang

Agreed. An update will be provided according to the agreement in the slides of document m30601.

m30216

Proposed update on MMT DIS

Sunghee Hwang

Potentially agreed. We will check with Cornelius and Mary Luc.

[MMT]Proposed modifications of delivery and signaling for ISO/IEC DIS 23008-1

Chang Ki Kim,Kwang-deok Seo, Jeongju Yoo, Jin Woo Hong

  1. Size of length was agreed to be modified and change is reflected in m30555

  2. table id changes are agreed with modifications

m30220

MMT: Version Management for subsets of MCIT and MPT

Shuichi Watanabe

A new revision has been uploaded with additional restrictions to resolve the version mismatch problem.

Agreed.


m30279

On layered codecs in MMT

Yago Sanchez,Cornelius Hellge, Thomas Schierl

  1. TBR after offline discussions

  2. Agreed. Clarification on usage of sidx.

  3. Agreed with following formulation of second sentence: Additionally, tracks with non-empty tref (e.g hint tracks) may be available.

m30280

Comments on Generic File Delivery in MMT

Cornelius Hellge, Yago Sanchez,Thomas Schierl

Noted. Concerns on duplicating functionality of packet_id.

m30348

Updates to Generic File Delivery




Noted. The document will be merged with m30555.

m30470

Modification of MCI table syntax to support carriage of the restructured CI

Yong Han Kim,Youngsun Ryu,Sungoh Hwang,Sungryeul Rhyu

Agreed. How to deliver other parts of CI, such as CSS, Javascript, Manifest, …

m30471

On high-level association of MMT assets with their signaling information for media consumption

Yong Han Kim

Noted. Add scheme_id to the MPT table just before the asset_id_length.

m30555

Restructuring of MMTP

Imed Bouazizi, Youngkwon Lim

First presentation is done. We will have a second presentation on Wednesday.

The second presentation was done and the following comments were collected:



  • Why not deliver signaling messages using GFD. This will be discussed when a contribution is available.

  • GFD M flag should be replaced by an indication in the code point definition. We will take this when contribution 384 is discussed.

  • Usage of RAP flag in the actual payloads needs to be clarified with mandatory statements.

  • Remove MSG header for now.

  • Move OI back to MPU mode and GFD mode

Final agreement will be checked on Thursday’s session.

Agreed with changes to correct field order and to merge the signaling of self-contained objects from m30348.



m30598

Proposed Update on MMT DIS and PDAM1

Y. He, Y. Ye

Agreed. Amd section is 7.3.3.

m30600

Proposed editorial text for MMT DIS

Kyungmo Park

Agreed.

m29741

Proposed MMT signaling message for ISO/IEC 23008-1 PDAM1

Changkyu Lee,Sunghei Kim,Shingak Kang

Noted.

m29742

Proposed modified description for QoS control in ISO/IEC 23008-1 PDAM1

Shingak Kang,Changkyu Lee,Sunghei Kim

The sentence “by utilizing …” is to be remove.

The section should be split into a first part that does not have any mention of CLI that goes to AMD 1. The second document would add the CLI related description and would go to AMD2.



m29743

Proposed modification for ARQ signaling for ISO/IEC 23008-1 PDAM1

Sunghei Kim,Changkyu Lee,Shingak kang

Agreed to remove profiles. Revision of this document is agreed after removing port number. We need to check what addressing information is needed to enable the different use cases. Use RFC 4588 as a reference.

m30192

ADC for capped VBR(Variable Bit Rate) asset

Doug Young SuhYongwoo Cho

Agreed to start a new core experiment to prove that the variance in produced bitrate is drastic to warrant this use case.

m30198

Proposed modification of signaling message for ARQ process in MMT

Chang Ki Kim,Kwang-deok Seo, Jeongju Yoo, Jin Woo Hong,

Agreed with some modifications.

m30378

Kyungmo Park

Agreed. The sentence on type_of_bitrate will be added. The rest will be included in the implementation guidelines.

m30600

Proposed editorial text for MMT DIS

Kyungmo Park

Agreed.

m30608

On applicability of certain cross-layer optimization techniques to MMT

Weimin Liu, Rahul Vanam, Liangping Ma, Gregory S. Sternberg,Yuriy A. Reznik

Agreed to start a new CE. Yuriy will provide the CE description.

m29573

MMT Header Compression CE report

Mary-Luc Champel

CE report needs updated based on the discussion of 30284.

m30284

Header Compression for MMT protocols

Mary-Luc Champel

Agree the principle of adding header compression. Agree to continue the CE, e.g. to investigate if a ROHC based approach would be an alternative. We need to keep some reserved bits in both versions of the protocol for use by header compression.
