    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.

    Abstract: A system and method for indicating whether a redundant picture can be used to replace a corresponding primary picture for inter-layer prediction. Various embodiments involve the use of a property of a redundant picture in relation to the corresponding primary picture. Based on such a property, a decoder can derive whether the redundant picture or a portion thereof can be utilized for inter-layer prediction of intra texture, macroblock coding mode, motion, and/or residual properties.

    Abstract: A system and method for enabling parallel decoder implementation for different views, even when there are existing dependencies between views. In various embodiments of the present invention, information is signaled to a decoder that slices are coded using certain constraints, so that parallel decoding of slices is possible. This signaling can be performed at a sequence parameter set level, or it could be performed at picture parameter set level, slice header level or macroblock header level. Additionally, the delay between various views is also signaled to the decoder, at the same location as the constraint information in various embodiments. Various algorithms can also be used to improve the coding efficiency of the system.

    Abstract: An explicit signaling element for controlling decoded picture output and applications when picture output is not desired. A signal element, such as a syntax element in a coded video bitstream, is used to indicate (1) whether a certain decoded picture is output; (2) whether a certain set of pictures are output, wherein the set of pictures may be explicitly signaled or implicitly derived; or (3) whether a certain portion of a picture is output. The signal element may be a part of the coded picture or access unit that it is associated with, or it may reside in a separate syntax structure from the coded picture or access unit, such as a sequence parameter set. The signal element can be used both by an encoder and a decoder in a video coding system, as well as a processing unit that produces a subset of a bitstream as output.

Zapping data may be provided by a zapping data provider or server, or may be created at the mobile terminal based on received program information. Zapping data may be provided to mobile terminals via a wireless multicast network, such as a DVB-H network, using a variety of timeslicing techniques, including providing a separate zapping data stream, providing zapping data as part of the source stream, or allowing mobile terminals to derive zapping data from the source content's broadcast stream. Zapping images may be selected from I-frames of video transmissions. An IP encapsulator may synchronize broadcast streams such that I-frames are transmitted concurrently, and at the beginning of timeslice bursts.

    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.

    Abstract: A method and device for error concealment in a video sequence. When there is a scene transition in the video sequence and there is an error in a picture belonging to the scene transition, an error concealment procedure based on the type of scene transition is used to conceal the error. The scene transition along with itsInformation about the type of the scene transition is provided to a video decoder in a supplemental enhancement information message. If the scene transition is a gradual scene transition, a spatio-temporal error concealment algorithm is used to conceal the picture. If the scene transition is a scene cut and only a part of the picture is lost or corrupted, a spatial error concealment is used to conceal the lost or corrupted part of the picture. If a whole picture belonging to the scene cut is lost or corrupted and the picture starts a new scene, it is not concealed.

    Abstract: There is disclosed a method, an apparatus, a server, a client and a non-transitory computer readable medium comprising a computer program stored therein for multi view video coding and decoding. View random access (VRA) pictures or access units are coded into a multiview bitstream. VRA pictures enable starting the decoding of a subset of the views present in the bitstream. The views selected to be accessible in VRA pictures are alternated in successive VRA pictures so that all views are gradually reconstructed when two or more VRA pictures have been decoded.
