The processor is configured to: decode signaled information about residual prediction reference picture generation; generate a residual prediction reference picture based on an enhancement layer reference picture and the decoded signaled information such that the generated residual prediction reference picture has the same motion field and the same picture order count (POC) as the enhancement layer reference picture from which it is generated; and store the generated residual prediction reference picture in the at least one reference picture list of the enhancement layer.

Abstract: In an example, the disclosure provides for receiving a coded video sequence comprising encoded pictures of a video sequence and receiving timing parameters for the coded video sequence that include an indication of whether a picture order count (POC) value for each picture in the coded video sequence that is not a first picture in the coded video sequence according to a decoding order is proportional to an output time of the picture relative to an output time of the first picture in the coded video sequence in a video parameter set (VPS) syntax structure referenced by the coded video sequence. Another example provides for encoding pictures of a video sequence to generate the coded video sequence comprising the encoded pictures and signaling timing parameters for the coded video sequence by signaling the indication in the VPS syntax structure referenced by the coded video sequence.

Abstract: This disclosure describes techniques for selection of coded picture buffer (CPB) parameters used to define a CPB for a video coding device for clean random access (CRA) pictures and broken link access (BLA) pictures in a video bitstream. A video coding device receives a bitstream including one or more CRA pictures or BLA pictures, and also receives a message indicating whether to use an alternative set of CPB parameters for at least one of the CRA pictures or BLA pictures. The message may be received from an external means, such as a processing means included in a streaming server or network entity. The video coding device sets a variable defined to indicate the set of CPB parameters for a given one of the pictures based on the received message, and selects the set of CPB parameters for the given one of the pictures based on the variable for the picture.

Abstract: Techniques for low-delay buffering in a video coding process are disclosed. Video decoding techniques may include receiving a first decoded picture buffer (DPB) output delay and a second DPB output delay for a decoded picture, determining, for the decoded picture, a first DPB output time using the first DPB output delay in the case a hypothetical reference decoder (HRD) setting for a video decoder indicates operation at a picture level, and determining, for the decoded picture, a second DPB output time using the second DPB output delay in the case that the HRD setting for the video decoder indicates operation at a sub-picture level.

Abstract: An optical mask can be made by providing a transparent mask substrate; depositing a first layer of opaque material, forming an aperture in the first layer; depositing a second layer of transparent material, depositing a third layer of transparent material; patterning the third layer to produce a disc-shaped region, heating the third layer until the disc-shaped region reflows into a lens-shaped region and cross-links, depositing a fourth layer, patterning the fourth layer to produce a cavity extending to the surface of the lens-shaped region, and dry etching the end of the cavity until the second layer develops a shape corresponding to the lens-shaped region.

Abstract: A video coder may, in some cases, signal whether one or more initial reference picture lists are to be modified. When an initial list is to be modified, the video coder can signal information indicating a starting position in the initial reference picture list. When the starting position signaled by the video coder is less than a number of pictures included in the initial reference picture list, then the video coder signals the number of pictures to be inserted into the initial reference picture list, and a reference picture source from which a picture can be retrieved to insert into the initial reference picture list to construct a modified reference picture list.

Abstract: In an example, the disclosure provides for encoding pictures of a video sequence to generate a coded video sequence comprising the encoded pictures and signaling timing parameters for the coded video sequence by directly signaling a condition for signaling a number of clock ticks corresponding to a difference of picture order count (POC) values equal to 1 in at least one of a video parameter set (VPS) syntax structure referenced by the coded video sequence and a sequence parameter set (SPS) syntax structure referenced by the coded video sequence. Another example provides for receiving timing parameters for a coded video sequence that include a condition for signaling a number of clock ticks corresponding to a difference of POC values equal to 1 directly in at least one of a VPS syntax structure referenced by the coded video sequence and an SPS syntax structure referenced by the coded video sequence.

Abstract: As one example, techniques for decoding video data include receiving a bitstream that includes one or more pictures of a coded video sequence (CVS), decoding a first picture according to a decoding order, wherein the first picture is a random access point (RAP) picture that is not an instantaneous decoding refresh (IDR) picture, and decoding at least one other picture following the first picture according to the decoding order based on the decoded first picture. As another example, techniques for encoding video data include generating a bitstream that includes one or more pictures of a CVS, wherein a first picture according to the decoding order is a RAP picture that is not an IDR picture, and avoiding including at least one other picture, other than the first picture, that corresponds to a leading picture associated with the first picture, in the bitstream.

Abstract: Techniques for encapsulating video streams containing multiple coded views in a media file are described herein. In one example, a method includes parsing a track of multiview video data, wherein the track includes one or more views, including only one of a texture view of a particular view and a depth view of the particular view. The method further includes parsing a track reference to determine a dependency of the track to a referenced track indicated in the track reference. Track reference types include ‘deps’ that indicates that the track includes the depth view and the reference track includes the texture view, ‘tref’ that indicates that the track depends on the texture view which is stored in the referenced track, and ‘dref’ that indicates that the track depends on the depth view which is stored in the referenced track.

Abstract: A file format design supports storage of multi-source multimedia presentations via the inclusion of indications as to whether a presentation is a multi-source presentation, and for one media type, the tracks of which are from different sources and should be played simultaneously. If a multi-source presentation exists, additional indications may be provided including: an indication of a multi-source presentation type being stored; indications regarding the source of each track and which tracks have the same source; indications of different parties' information such as phone numbers, etc. Thus, a player may play back a recorded presentation in the same or substantially the same manner as it was presented during the actual session, and may automatically manipulate the presentation to be more informative or efficient. The file format design further supports storage of other types of multi-source presentations that render more than one media stream for at least one type of media.

Abstract: A device performs a decoding process as part of a bitstream conformance test. As part of the decoding process, the device performs a bitstream extraction process to extract, from a bitstream, an operation point representation of an operation point defined by a target set of layer identifiers and a target highest temporal identifier. The target set of layer identifiers contains values of layer identifier syntax elements present in the operation point representation, the target set of layer identifiers being a subset of values of layer identifier syntax elements of the bitstream. The target highest temporal identifier is equal to a greatest temporal identifier present in the operation point representation, the target highest temporal identifier being less than or equal to a greatest temporal identifier present in the bitstream. The device decodes network abstraction layer (NAL) units of the operation point representation.

Abstract: A method for processing video data in a real-time transport protocol (RTP) payload includes encapsulating video data in a single network abstraction layer (NAL) unit packet for an RTP session. The single NAL unit packet contains a single NAL unit. The method may also include encapsulating decoding order number information in the single NAL unit packet based on at least one of: the RTP session being in a multi-stream transmission (MST) mode, or a maximum number of NAL units that may precede the NAL unit in a de-packetization buffer in reception order and follow the NAL unit in decoding order being greater than 0.

Abstract: A video encoder generates, based on a reference picture set of a current view component, a reference picture list for the current view component. The reference picture set includes an inter-view reference picture set. The video encoder encodes the current view component based at least in part on one or more reference pictures in the reference picture list. In addition, the video encoder generates a bitstream that includes syntax elements indicating the reference picture set of the current view component. A video decoder parses, from the bitstream, syntax elements indicating the reference picture set of the current view component. The video decoder generates, based on the reference picture set, the reference picture list for the current view component. In addition, the video decoder decodes at least a portion of the current view component based on one or more reference pictures in the reference picture list.

Abstract: A video encoder generates a bitstream that includes a syntax element that indicates whether a picture is encoded according either a first coding mode or a second coding mode. In the first coding mode, the picture is entirely encoded using wavefront parallel processing (WPP). In the second coding mode, each tile of the picture is encoded without using WPP and the picture may have one or more tiles. A video decoder may parse the syntax element from the bitstream. In response to determining that the syntax element has a particular value, the video decoder decodes the picture entirely using WPP. In response to determining that the syntax element does not have the particular value, the video decoder decodes each tile of the picture without using WPP.

Abstract: A video decoder may be configured to decode a first value representative of a difference between a base most significant bits (MSBs) value of a picture order count (POC) value of a current picture of video data and a first MSBs value of a first POC value of a first long-term reference picture of the video data, decode a second value representative of a difference between a second MSBs value of a second POC value of a second long-term reference picture of the video data and the first MSBs value, wherein the first POC value and the second POC value have different least significant bits values, and decode at least a portion of a current picture of the video data relative to at least one of the first long-term reference picture and the second long-term reference picture.
