AHG9: On grouping the SEI prefix data as a new SEI message
Authors: Lulin Chen MediaTek Olena Chubach MediaTek Y.-W. Huang MediaTek S. Lei MediaTek
Abstract
Considering both the wrapping flag and the prefix flag are used as the special cases for the SEI processing order SEI message, to further simplify the syntax structure of the SEI processing order SEI message, this contribution proposes to group the SEI prefix data related syntax structure as a new SEI message – the processing order prefix matching SEI message.

JVET-AG0166 AHG9: On grouping the SEI prefix data as a new SEI message [L. Chen, O. Chubach, Y. Huang, S. Lei (MediaTek)]

Chaired by J. Boyce.

Considering both the wrapping flag and the prefix flag are used as the special cases for the SEI processing order SEI message, to further simplify the syntax structure of the SEI processing order SEI message, this contribution proposes to group the SEI prefix data related syntax structure as a new SEI message – the processing order prefix matching SEI message.

The modified text for the SEI processing order SEI message in this document (JVET-AG0166) and a separate contribution JVET-AG00165 are combined in another contribution JVET-AG0168 for overall clarity and completeness.

An expert asserted that the proposed change would require that a decoder associate the SPO SEI message and the proposed new SEI message. Another expert suggested that a specified ordering of the SEI messages could make the association easier. No action was taken on this.
