6.3HL syntax for range extensions and single-layer HEVC coding (5)
JCTVC-M0042 No display SEI message [J. Boyce, D. Hong, W. Jang (Vidyo)]
Chaired by Y-.K. Wang.
A “no display” SEI message is proposed, which indicates that a coded picture be decoded but not displayed. JCTVC-L0179 proposed the same SEI message as one of several options to enable a middle box to make a change to a coded bitstream to indicate that a particular picture not be displayed. During the Geneva meeting, discussion on several SEI messages was postponed until after the technical freeze of HEVC version 1. The meeting notes for the review of JCTVC-L0179 note at the end, “Tentative plan is to consider creating an SEI message in a future version.” The proposed SEI message is suggested for adoption for the next HEVC release.
It is noted that the functionality provided by the proposal is the same as in the AVC full-frame freeze SEI message, but with simplified persistence characteristics.
Decision: Adopt (into RExt draft), with the persistence scope to be changed to apply to the associated picture.
