Abstract: A method and related apparatus for decoding an image sequence from a bitstream, wherein an identifier indicating if all output pictures are decodable with a predefined set of reference pictures is decoded;an indication of required reference pictures for a given output picture is decoded; the indicated at least one reference picture for the given output picture is decoded; and the at least one output picture is decoded.

Abstract: Various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments a data structure is encoded that is associated with a base-layer picture and an enhancement-layer picture in a file or a stream comprising a base layer of a first video bitstream and/or an enhancement layer of a second video bitstream, wherein the enhancement layer may be predicted from the base layer; and into the data structure information that is indicative of whether the base-layer picture is regarded as an intra random access point picture for enhancement layer decoding is also encoded. If the base-layer picture is regarded as an intra random access point picture for enhancement layer decoding; the data structure information is further indicative of the type of the intra random access point IRAP picture for the decoded base-layer picture to be used in the enhancement layer decoding.

Abstract: A method for decoding an encoded video representation from a bitstream, the method comprising decoding an identifier indicating that all samples within a scope of the bitstream have been coded with a prediction restriction; determining that the scope covers a region of interest within a picture; decoding at least a first coding unit preceding said region of interest in decoding order in a parse mode such that syntax elements belonging to said at least first coding unit are parsed, but a sample reconstruction process of said syntax elements is omitted; and decoding at least a second coding unit belonging to said region of interest such that syntax elements belonging to said at least second coding unit are parsed and a sample reconstruction process is performed to said syntax elements.

Abstract: An indirect aggregator NAL unit for the SVC file format and RTP payload format for video coding. The indirect aggregator NAL unit of the present invention enables easy identification of scalability dependencies within a bit stream, thereby enabling fast and efficient stream manipulation. Furthermore, the indirect aggregator NAL unit of the present invention ensures that a base layer of the streams can still be processed with a H.264/AVC decoder, AVC file format parser, and H.264/AVC RTP payload parser.

Abstract: A method of encoding scalable video data having multiple layers where each layer in the multiple layers is associated with at least one other layer includes identifying one or more layers using a first identifier where the first identifier indicates decoding dependency, and identifying reference pictures within the identified one or more layers using a second identifier. The coding of the second identifier for pictures in a first layer is independent of pictures in a second enhancement layer. As such, for all pictures with a certain value of DependencyID, the syntax element frame_num is coded independently of other pictures with different values of DependencyID. Within all pictures with a pre-determined value of DependencyID, a default frame_num coding method is used.

Abstract: A method of encoding a plurality of views of a scene into a multi-view video bitstream, the method comprising: determining that a first picture of a first view is used as a reference picture for a second picture of another view; based on said determining that said first picture of said first view is used as a reference picture for said second picture of another view, providing, in said bitstream, a first signaling element indicating that said first picture is treated as a longterm reference picture for said second picture; and using said first picture as a long-term reference picture for said second picture in said encoding.

Abstract: Un método para decodificar vídeo codificado, comprendiendo el método: recibir (1200) imágenes codificadas de una primera capa de escalabilidad que comprende una o más subcapas temporales; decodificar (1202) las imágenes codificadas de la primera capa de escalabilidad; recibir (1204) imágenes codificadas de una segunda capa de escalabilidad que comprende una o más subcapas temporales, dependiendo la segunda capa de escalabilidad de la primera capa de escalabilidad; seleccionar (1206) una imagen de acceso de capa en la segunda capa de escalabilidad a partir de las imágenes codificadas de la segunda capa de escalabilidad, en donde la imagen de acceso de capa seleccionada es una imagen de step-wise temporal sub-layer access (acceso de subcapa temporal por etapas - STSA) en una subcapa temporal más baja, posibilitando la imagen STSA la decodificación de imágenes posteriores, en orden de decodificación, en la misma subcapa temporal, en donde no se permite la interpredicción de ninguna imagen en la misma subcapa temporal antes de dicha imagen STSA, en orden de decodificación; ignorar (1208) imágenes codificadas en la segunda capa de escalabilidad antes, en orden de decodificación, de la imagen de acceso de capa seleccionada; y decodificar (1210) o seleccionar la imagen de acceso de capa seleccionada y las imágenes posteriores, si las hay, en orden de decodificación, en la misma o una subcapa temporal superior.
