Definitions

  • the present principles relate generally to video encoding and decoding and, more particularly, to methods and apparatus for use in a multi-view video coding system.
  • Multi-view Video Coding MVC
  • ISO/IEC International Organization for Standardization/International Electrotechnical Commission
  • MPEG-4 MPEG-4 Part 10 Advanced Video Coding
  • ITU-T Telecommunication Sector
  • MPEG-4 AVC standard Multi-view Video Coding
  • a method has been proposed to enable efficient random access in multi-view compressed bit streams.
  • a V-picture type and a View Dependency Supplemental Enhancement Information (SEI) message are defined.
  • SEI View Dependency Supplemental Enhancement Information
  • a feature required in the proposed V-picture type is that V-pictures shall have no temporal dependence on other pictures in the same camera and may only be predicted from pictures in other cameras at the same time.
  • the proposed View Dependency Supplemental Enhancement Information message will describe exactly which views a V-picture, as well as the preceding and following sequences of pictures, may depend on. The following are the details of the proposed changes.
  • V-Picture syntax and semantics a particular syntax table relating to the MPEG-4 AVC standard is extended to include a Network Abstraction Layer (NAL) unit type of 14 corresponding to a V-picture. Also, the V-picture type is defined to have the following semantics:
  • NAL Network Abstraction Layer
  • V-picture A coded picture in which all slices reference only slices with the same temporal index (i.e., only slices in other views and not slices in the current view). When a V-picture would be output or displayed, it also causes the decoding process to mark all pictures from the same view which are not IDR-pictures or V-pictures and which precede the V-picture in output order to be marked as “unused for reference”. Each V-picture shall be associated with a View Dependency SEI message occurring in the same NAL.
  • a View Dependency Supplemental Enhancement Information message is defined with the following syntax:
  • view_dependency ( payloadSize ) ⁇ num_seq_reference_views ue(v) seq_reference_view_0 ue(v) seq_reference_view_1 ue(v) ... seq_reference_view_N ue(v) num_pic_reference_views ue(v) pic_reference_view_0 ue(v) pic_reference_view_1 ue(v) ...
  • num_seq_reference_views/num_pic_reference_views denotes the number of potential views that can be used as a reference for the current sequence/picture
  • seq_reference_view_i/pic_reference_view_i denotes the view number for the i th reference view.
  • the picture associated with a View Dependency Supplemental. Enhancement Information message shall only reference the specified views described by pic_reference_view_i. Similarly, all subsequent pictures in output order of that view until the next View Dependency Supplemental Enhancement Information message in that view shall only reference the specified views described by seq_reference_view_i.
  • a View Dependency Supplemental Enhancement Information message shall be associated with each Instantaneous Decoding Refresh (IDR) picture and V-picture.
  • At least one drawback of this method is the complexity introduced in the decoder due to the dependency being recursively obtained. Additionally, this method requires that every V-picture carry an SEI message (which is a non-normative part of the MPEG-4 AVC standard), resulting in the dependency being unable to be used for normative behavior such as reference picture selection.
