    Abstract: Joint coding of depth map video and texture video is provided, where a motion vector for a texture video is predicted from a respective motion vector of a depth map video or vice versa. For scalable video coding, depth map video is coded as a base layer and texture video is coded as an enhancement layer(s). Inter-layer motion prediction predicts motion in texture video from motion in depth map video. With more than one view in a bit stream (for multi view coding), depth map videos are considered monochromatic camera views and are predicted from each other. If joint multi-view video model coding tools are allowed, inter-view motion skip issued to predict motion vectors of texture images from depth map images. Furthermore, scalable multi-view coding is utilized, where interview prediction is applied between views in the same dependency layer, and inter-layer (motion) prediction is applied between layers in the same view.

    Abstract: The time until a media decoder is refreshed to produce correct output samples is minimized if an IDR picture is the first picture in a decoding order in each MPE-FEC frame. A system enabling minimization of tune-in delay is described. Aspects of the system include a content encoder for receiving a source signal including first and second bit streams and for encoding the first and second bit streams, the encoded first bit stream including a decoder refresh bit stream and the encoded second bit stream including a media bit stream. A server receives the encoded first and second bit streams and encapsulates the encoded first and second bit streams into packets. An encapsulator then receives the packets and composes a time-sliced multi-protocol encapsultation (MPE) stream by replacing a spliceable picture from the encoded second bit stream.

    Abstract: In a start code based bistream structure for use in video coding, a picture header is used simultaneously with the parameter set in the start code. The picture header is present before the slice header in the same picture. As such, it is possible to allow the presence of at least one sequence parameter set or picture parameter set before the slice header. In a NAL unit parameter set bitstream structure, the picture head NAL unit is present before the slice NAL unit. In either structure, the picture header information must remain unchanged during the decoding of the entire picture, but should change more frequently between pictures as compared to the information in the picture parameter set.
