Abstract: A multi-layer video decoder is configured to determine, based on a list of triplet entries, whether the multi-layer video decoder is capable of decoding a bitstream that comprises an encoded representation of the multi-layer video data. The number of triplet entries in the list is equal to a number of single-layer decoders in the multi-layer video decoder. Each respective triplet entry in the list of triplet entries indicates a profile, a tier, and a level for a respective single-layer decoder in the multi-layer video decoder. The multi-layer video decoder is configured such that, based on the multi-layer video decoder being capable of decoding the bitstream, the multi-layer video decoder decodes the bitstream.

Abstract: Information for a video stream indicating whether the video stream includes stereoscopic three-dimensional video data can be provided to a display device. This information allows the device to determine whether to accept the video data and to properly decode and display the video data. This information can be made available for video data regardless of the codec used to encode the video. Systems, devices, and methods for transmission and reception of compatible video communications including stereoscopic three-dimensional picture information are described.

Abstract: Methods for coding an inter-layer reference picture set (RPS) and coding end of bitstream (EoB) network access (NAL) units in multi-layer coding are disclosed. In one aspect, the method includes determining whether a candidate inter-layer reference picture is present in the video information. The video information includes an inter-layer RPS including a plurality of subsets. The method further includes determining an inter-layer RPS subset to which the candidate inter-layer reference picture belongs in response to determining that the candidate inter-layer reference picture is not present, and indicating that no reference picture is present in the inter-layer RPS subset to which the candidate inter-layer reference picture belongs.

Abstract: A video coding device, such as a video encoder or a video decoder, may be configured to decode a duration between coded picture buffer (CPB) removal time of a first decoding unit (DU) in an access unit (AU) and CPB removal time of a second DU, wherein the first DU comprises a non-video coding layer (VCL) network abstraction layer (NAL) unit with nal_unit_type equal to UNSPEC0, EOS_NUT, EOB_NUT, in the range of RSV_NVCL44 to RSV_NVCL47 or in the range of UNSPEC48 to UNSPEC63. The video decoder determines a removal time of the first DU based at least in part on the decoded duration and decodes video data of the first DU based at least in part on the removal time.

Abstract: Bitstream restrictions or constraints on the partitioning of pictures across layers of video data are described. In some examples, the number of tiles per picture for each layer of a plurality of layers is constrained based on a maximum number of tiles per picture for the layer. In some examples, the number of tiles per picture for each layer of the plurality of layers is no greater than the maximum number of tiles per picture for the layer. In some examples, a sum of the numbers of tiles per picture for the plurality of layers is no greater than a sum of the maximum numbers of tiles per picture for the plurality of layers. In some examples, a second largest coding unit (LCU) or coding tree block (CTB) size for a second layer is constrained based on, e.g., to be equal to, a first LCU size for a first layer.

Abstract: A device and method of decoding video data that includes decoding the video data to generate decoded video data of a current frame of the video data, and extracting an updated regions message from the decoded video data and determining updated region location information of the current frame based on the updated regions message. An updated region of the current frame is identified based on the updated region location information, the updated region being less than a total size of the current frame, and both the identified updated region and decoded video data of the current frame that has not been updated are transmitted for display of the current frame of the video data.

Abstract: A computing device generates a file that comprises a track box that contains metadata for a track in the file. Media data for the track comprises a sequence of samples, each of the samples being a video access unit of multi-layer video data. As part of generating the file, the computing device generates, in the file, a sub-sample information box that contains flags that specify a type of sub-sample information given in the sub-sample information box. When the flags have a particular value, a sub-sample corresponding to the sub-sample information box contains exactly one coded picture and zero or more non-Video Coding Layer (VCL) Network Abstraction Layer (NAL) units associated with the coded picture.
