  • Patent number: 8774284
    Abstract: The exemplary embodiments of this invention provide in one aspect thereof an ability to signal multiple decoding times for each sample in a file format level in order to allow, for example, different decoding times for each sample (or sample subset) between decoding an entire stream and decoding a subset of the stream. An alternate decoding time box is specified to allow for the signaling of multiple decoding times for each sample. Such a box can contain a compact version of a table that allows indexing from an alternate decoding time to a sample number, where an alternate decoding time is a decoding time to be used with a sample when only a subset of an elementary stream stored in a track is to be decoded. Furthermore, each entry in the table provides the number of consecutive samples with the same time delta, and the delta between those consecutive samples. By adding the deltas a complete time-to-sample map can be constructed.

  • Patent number: 8767836
    Abstract: The use of a picture delimiter that is contained in a NAL unit type value that is reserved in the current AVC or SVC specification. The present invention provides the scalability information for the H.264/AVC base layer in such a manner that bitstreams remain decodable with H.264/AVC decoders. In addition, the picture delimiter of the present invention may contain many other syntax elements that can help in easier processing of bitstreams compared to the plain H.264/AVC bitstream syntax.

  • Patent number: 8767818
    Abstract: An indirect aggregator NAL unit for the SVC file format and RTP payload format for video coding. The indirect aggregator NAL unit of the present invention enables easy identification of scalability dependencies within a bit stream, thereby enabling fast and efficient stream manipulation. Furthermore, the indirect aggregator NAL unit of the present invention ensures that a base layer of the streams can still be processed with a H.264/AVC decoder, AVC file format parser, and H.264/AVC RTP payload parser.

  • Patent number: 8761564
    Abstract: A modular connector assembly is provided that has both an electrical coupling configuration that complies with the RJ-45 wiring standard and an optical coupling configuration that provides the assembly with optical communications capabilities. In addition, the modular connector assembly is configured to have backwards compatibility with existing 8P8C jacks and plugs that implement the RJ-45 wiring standard. Consequently, the modular connector assembly may be used to communicate optical data signals at higher data rates (e.g., 10 Gb/s and higher) or to communicate electrical data signals at lower data rates (e.g., 1 Gb/s).

    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.

  • Publication number: 20140140399
    Abstract: A method of coding video data includes receiving video information associated with a first layer and a second layer and determining whether at least one of the first layer and the second layer is a default layer. The method can include at least partially restricting inter-layer prediction when neither the first layer nor the second layer is the default layer. A default layer can be a base layer or an enhancement layer. A flag can be received that indicates that inter-layer prediction is to be restricted. In addition, the method can include determining whether inter-layer prediction is allowed for the video information associated with the first layer, and determining whether inter-layer prediction is partially allowed for the video information associated with the second layer such that motion compensation is not used with the second layer video information.

  • Publication number: 20140133556
    Abstract: In an example, a video coder may determine a first layer component of a first layer of video data, wherein the first layer of video data is associated with a layer identifier. The video coder may generate at least one filtered layer component by filtering the first layer component, and assign the layer identifier of the first layer and a filtered layer component index to the at least one filtered layer component, where the filtered layer component index is different than a layer component index of the first layer component. The video coder may also add the at least one filtered layer component to a reference picture set for performing inter-layer prediction of a layer other than the first layer of video data.

  • Publication number: 20140098895
    Abstract: A video encoder signals, in an encoded video bitstream, a video parameter set (VPS) that includes a plurality of Hypothetical Reference Decoder (HRD) parameter syntax structures that each include HRD parameters. For each respective HRD parameter syntax structure in the plurality of HRD parameter syntax structures, the VPS further includes a syntax element indicating whether the HRD parameters of the respective HRD parameter syntax structure include a common set of HRD parameters in addition to a set of sub-layer-specific HRD parameter information specific to a particular sub-layer of the encoded video bitstream. The common set of HRD parameters is common to all sub-layers of the encoded video bitstream. A video decoder or other device decodes, from the encoded video bitstream, the VPS and performs an operation using the HRD parameters of at least one of the HRD parameter syntax structures.
