Hi —
There’s one wording change we’re making in the VP9 payload spec that Zahed
asked me to verify with the working group.
The text change is as follows:
OLD:
U: Switching up point. If this bit is set to 1 for the
current picture with temporal layer ID equal to TID, then "switch up"
to a higher frame rate is possible as subsequent higher temporal layer
pictures
will not depend on any picture before the current picture (in
coding order) with temporal layer ID greater than TID.
NEW:
U: Switching up point. When this bit is set to one, if the
current picture has a temporal-layer ID equal to value T, then
subsequent pictures with temporal-layer ID values higher than T
will not depend on any picture before the current picture (in
coding order) witha temporal-layer ID value greater than T.
This should be the same concept, hopefully explained more clearly. Please let
me know if you have any issues with this change.
Thanks!
Jonathan
