  • Publication number: 20220256176
    Abstract: In one embodiment, a method determines an encoded plurality of layers for a scalable video stream for a video where each of the plurality of layers includes a respective layer parameter setting. An additional layer for the plurality of layers is determined where the additional layer enhances a base layer in the plurality of layers and the respective layer parameter settings for the encoded plurality of layers do not take into account the additional layer. The method then determines an additional layer parameter setting for the additional layer. The additional layer parameter setting specifies a relationship between the additional layer and at least a portion of the plurality of layers where the additional layer parameter setting is used to decode the additional layer and the at least a portion of the plurality of layers.

  • Publication number: 20210409752
    Abstract: A sequence of picture slices is encoded as reference slices and non-reference slices, wherein the reference slices include B slices, by forming, for each B slice, at least one data packet containing data values derived from brightness and color information pertaining to the slice. The data packet for each B slice includes a header element indicating whether the B slice is a reference slice. The header element of each reference B slice has a value that depends on depth of the reference B slice in a hierarchy of discardability.
