Meeting Minutes of the 44th IEEE C/DC 1857 Working Group Plenary Meeting

The 44th meeting of the IEEE C/DC 1857 Working Group was held via conference call, quorum reached. The meeting was hosted by Dr. Siwei Ma, the chair of 1857 WG.

Dr. Siwei Ma presented the patent slides at the meeting. A call for potentially essential patents was made, and no potentially essential patent claims were declared, and no holders of potentially essential patents were identified. All members could ask for the IEEE official patent document from the secretariat. The IEEE copyright policy statement was presented then, and no question raised.

Approval of the Agenda

Motion to approve the meeting agenda. (Mover: Dr. Dong Liu; Second: Ms. Xiaoxu Luan). The agenda was unanimously approved as presented without objection.

1857.9 Standard for Immersive Visual Content Coding

The draft standard was unanimously approved by RevCom on November 10th, 2021. The draft standard is on sale via

1857.10Third Generation Video Coding

The draft standard was unanimously approved by RevCom on November 10th, 2021. The draft standard is on sale via

1857.11-Neural Network-Based Image Coding

The group received and discussed 8 technical proposals. 1 technical proposal is about the Test Model for Deep Learning-Based Image Compression, namely NIC. 4 technical proposals are about the explorative experiments upon NIC, including pre- and post-processing, entropy coding optimization, variable-rate coding, and rate control. 3 technical proposals are about the incoming call-for-proposal or the standardization. 3 technical proposals are adopted. FVC-SG plans to issue the Call for Proposals on Neural Network-Based Image Coding in December, and to continue the explorative experiments to improve the compression performance and to reduce the encoding/decoding complexity.

1857.12-Standard for Smart Media Transport

The sub-working group has been officially  approved and established in September. The group had internal meetings during this week and decided to start the draft standard writing as soon as possible.

Revision Projects-P1857, P1857.2, P1857.3

All 3 REV projects (1857-Rev, 1857.2-Rev, 1857.3-Rev)are working on the revision, and are planned to be completed next year.
