摘要： A 3-dimensional (3D) video transmitter may be operable to encode a 3D video to generate a scalable video coding (SVC) base layer and a SVC enhancement layer. A first view such as a first high-resolution view and a second view such as a second high-resolution view of the 3D video in the SVC enhancement layer may be separate frames. A first half-resolution view and a second half-resolution view of the 3D video in the SVC base layer may be packed in a single frame. The first half-resolution view in the SVC base layer may be a base-layer reference for the first high-resolution view in the SVC enhancement layer for inter-layer prediction of spatial scalable coding. The first high-resolution view in the SVC enhancement layer may be an intra-layer reference for the second high-resolution view in the SVC enhancement layer for intra-layer prediction of temporal scalable coding.

摘要： Disclosed are various embodiments of three-dimensional (3D) video coding using scalable video coding (SVC) spatial scalability. In one embodiment, 3D video is encoded to generate a SVC base layer that includes a left first-resolution view and a right first-resolution view packed in a first frame. 3D video is encoded to generate a SVC enhancement layer that includes a left second-resolution view and a right second-resolution view packed in a second frame. The left second-resolution view and the right second-resolution view may have a higher spatial resolution than the left first-resolution view and the right first-resolution view.

摘要： Methods and systems for processing B pictures with missing or invalid forward reference pictures are disclosed. Aspects of one method may include decoding of a contiguous sequence of B pictures that immediately follow a first I picture after a sequence header. The decoding of the B pictures may handle video edit codes in the AVS1-P2 format and/or random access points. Some embodiments of the invention may discard B pictures that refer to invalid or missing forward reference pictures, while other embodiments of the invention may interpolate B pictures. For an invalid forward reference picture, the interpolation algorithm for generating pictures may use the invalid forward reference picture and the backward reference picture. For a missing decoded forward reference picture, as in a random access, the interpolation algorithm for generating pictures may use the backward reference picture.

摘要： Aspects of a method and system for processing audio and video transport may comprise synchronizing streams with associated program content based on 24-bit presentation time stamps (PTSs) and 32-bit system clock samples (SCSs) field without using decoding time stamps (DTSs). A PTS field may be provided as part of a packetized elementary stream (PES) packet syntax. An SCS field may be provided as part of a transport stream (TS) syntax. A system clock (STC) may be determined from received SCS values. Video and/or audio data may be decoded as soon as they arrive and when there is at least one display and/or presentation frame buffer available. The video and/or audio data may be presented for display and/or play based on a comparison of the PTS and STC values. When a frame does not have an associated PTS, a PTS extrapolation operation may generate an extrapolated PTS value from previously received PTSs.

摘要： In conventional packet communications systems, such as MPEG-2, the data stream includes a program clock reference (PCR) so that the receiver decoder can lock on to the data stream. The invention eliminates the need to send the PCR by transferring a data transport rate explicitly in the header of the data packets so that the decoder can use the transport rate as a locking reference and adjust its phase lock loop. The transport rate is carried in the adaptation field as user private data.
