Definitions

  • the video data may be packetized for transmission or storage.
  • the video data may be assembled into a video file conforming to any of a variety of standards, such as the International Organization for Standardization (ISO) base media file format and extensions thereof, such as AVC.
  • ISO International Organization for Standardization
  • sequence data sets may include, for example, sequence parameter sets, picture parameter sets, and some Supplemental Enhancement Information (SEI) messages, such as, for example, sequence level SEI messages.
  • SEI Supplemental Enhancement Information
  • These techniques may include decoupling the sequence data sets from the coded video pictures described by the sequence data sets. That is, rather than including sequence level SEI messages with coded video pictures described by the sequence level SEI messages, the techniques of this disclosure may include decoupling the sequence level SEI messages from the coded video pictures. Accordingly, the sequence level SEI messages may be transferred from a source device to a destination device separately from the coded video pictures. In some examples, a sequence data set including the sequence level SEI messages may be transferred from the source device to a destination device before transfer of the coded video pictures to which the sequence data sets pertain.
  • SEI Supplemental Enhancement Information
  • a sequence data set which may include, e.g., a sequence parameter set, a picture parameter set, and sequence level SEI messages, may be included in a parameter set track or a parameter set elementary stream, in accordance with the techniques of this disclosure.
  • the techniques of this disclosure may be applied to video files or video streams conforming to MPEG-2 Systems, including Packetized Elementary Stream (PES), Program Stream (PS), and Transport Stream (TS), and their AVC, SVC, and MVC extensions.
  • PES Packetized Elementary Stream
  • PS Program Stream
  • TS Transport Stream
  • a NAL unit including video data in its payload may comprise various granularity levels of video data.
  • a NAL unit may comprise a block of video data, a macroblock, a plurality of macroblocks, a slice of video data, or an entire frame of video data.
  • Encapsulation unit 30 may receive encoded video data from video encoder 28 in the form of PES packets of elementary streams. Encapsulation unit 30 may associate each elementary stream with a corresponding program.
  • an access unit may comprise a coded picture in one time instance, which may be presented as a primary coded picture. Accordingly, an access unit may comprise all audio and video frames of a common temporal instance, e.g., all views corresponding to time X.
  • This disclosure also refers to an encoded picture of a particular view as a "view component.” That is, a view component may comprise an encoded picture (or frame) for a particular view at a particular time. Accordingly, an access unit may be defined as comprising all view components of a common temporal instance.
  • the decoding order of access units need not necessarily be the same as the output or display order.
  • the ITU-T H.264 standard supports intra prediction in various block sizes, such as 16 by 16, 8 by 8, or 4 by 4 for luma components, and 8x8 for chroma components, as well as inter prediction in various block sizes, such as 16x16, 16x8, 8x16, 8x8, 8x4, 4x8 and 4x4 for luma components and corresponding scaled sizes for chroma components.
  • "x" and “by” may be used interchangeably to refer to the pixel dimensions of the block in terms of vertical and horizontal dimensions, e.g., 16x16 pixels or 16 by 16 pixels.
  • an NxN block generally has N pixels in a vertical direction and N pixels in a horizontal direction, where N represents a nonnegative integer value.
  • the pixels in a block may be arranged in rows and columns.
  • SEI messages may be used for a variety of purposes.
  • the sequence level SEI messages may describe pan-and-scan information for adjusting video data to accommodate various screen sizes when displayed.
  • video output 44 (or a control unit thereof) may use the sequence level SEI messages to adjust the video data to be displayed by video output 44.
  • Multiview scene information may also describe characteristics of one or more cameras or conditions during image acquisition, such as, for example, what is the maximum disparity caused by camera settings of, e.g., up to 1024 views.
  • the multiview scene information may also provide details relevant to camera calibration and rectification.
  • video decoder 48 and/or video display 44 may use the sequence level SEI messages to determine how to adapt the video data to a native resolution of video display 44, determine whether an image is a left or right image (e.g., for stereo video data), determine how frames are packed, determine scalability information for the video data, determine multiview acquisition information, and/or determine multiview scene information.
  • sequence level SEI messages may be used to determine how to adapt the video data to a native resolution of video display 44, determine whether an image is a left or right image (e.g., for stereo video data), determine how frames are packed, determine scalability information for the video data, determine multiview acquisition information, and/or determine multiview scene information.
  • Video data track 244 corresponds to a number of various video fragments 254A-254C, each of which may be stored in MDAT box 250.
  • each set of video fragments 254A, 254B, and 254C may have different sequence level information.
  • the sequence level information may change between video fragments 254A, 254B, and 254C.
  • each of video fragments 254A, 254B, and 254C may have a respective sequence data set.
  • sequence data set 252A relates to video fragments 254A
  • sequence data set 252B relates to video fragments 254B
  • sequence data set 252C relates to video fragments 254C.
