Abstract: A primary device that provides information, the primary device comprising: (a) said primary device configured to provide said information including at least one of: (i) a media playback state for a media identification associated with a media playback state information subscription including at least one of: (1) playing; (2) paused; (3) stopped; relative to normal speed including at least one of: (1) a positive speed value indicating forward playback, wherein said forward playback means a media timeline position increases as wall-clock time increases; and (2) a negative speed value indicating backward playback, wherein said backward playback means a media timeline position decreases as wall-clock time decreases.

Abstract: A device may be configured to signal output layer set information according to one or more of the techniques described herein. The device comprising one or more processors configured to: receiving a video parameter set including syntax elements; parsing first syntax element from the video parameter set specifying whether at least one output layer set specified by the video parameter set contains more than one layer; and parsing second syntax element specifying whether the video parameter contains sequence-level hypothetical reference decoder parameters in a case that the first syntax element specifies that at least one output layer set specified by the video parameter set contains more than one layer.

Abstract: This disclosure relates to video coding and more particularly to techniques for signaling temporal sub-layer information for coded video. According to an aspect of an invention, a range of a value of a third syntax element in a sequence parameter set is determined based on whether the sequence parameter set refers to a video parameter set, wherein the third syntax element specifies a maximum number of temporal sub-layers that is present in each coded video sequence referring to the sequence parameter set.

Abstract: A method of encoding video data by an electronic device is provided. A plurality of picture parameters included in a picture header of a picture in the video data is signaled into a bitstream. A present flag included in a sub-picture header of a sub-picture generated by dividing the picture is signaled into the bitstream. The electronic device determines, based on the present flag, whether a specific one of a plurality of sub-picture parameters is determined based on the sub-picture header or the picture header. The specific one of the plurality of sub-picture parameters corresponds to the specific one of the plurality of picture parameters. The sub-picture is reconstructed based on the specific one of the plurality of sub-picture parameters when the specific one of the plurality of sub-picture parameters is determined from the sub-picture header.

Abstract: This disclosure relates to video coding and more particularly to techniques for signaling decoded picture buffer information for coded video data. The method of decoding video data comprises, determining a number of output layer sets with more than one layer; determining a number of decoded picture buffer parameters syntax structures in a video parameter set; in a case that the number of the decoded picture buffer parameters syntax structures is not equal to the number of the output layer sets with more than one layer, decoding a syntax element specifying an index of the decoded picture buffer parameters syntax structures; and in a case that the syntax element is not present, inferring a value of the syntax element.

Abstract: A method of decoding video data by a device is provided. A first flag syntax in a picture parameter set is decoded. The first flag specifies whether tiles within each slice are in raster scan order or the tiles within each slice cover a rectangular region of a picture. The method determines, based on the first flag syntax, whether a slice address syntax is present in a slice header. The slice address syntax is decoded when the slice address is present in the slice header.
