摘要： The invention relates to a method of generating a synthesized image representing a view of a scene from a first input image representing the view and a second input image representing the view, the synthesized image comprising synthesized image positions, by assigning a synthesized image data value to a synthesized image position. The method comprises determining whether input images have at the synthesized image position data values associated with them. If either one has a data value associated, that data value is assigned to the synthesized image position. If both, an average of both values is assigned. The average is a weighed average, with weighing factors being a function of a distance or distances to a closest image position with no image data value or valid image data value assigned.

摘要： A technique for encoding and decoding data pertaining to multiple video views is presented. A method embodiment of the encoding technique comprises the steps of providing first picture stream belonging to a first view and performing a first encoding operation to encode a picture of the first picture stream. The first encoding operation is based on a single-view video codec and provides encoder state information relevant for the encoding of another picture of the first picture stream. Also provided is a second picture stream belonging to a second video view. A second encoding operation is performed to encode a picture of the second picture stream based on the single-view video codec, wherein the second encoding operation is based on the encoder state information provided by the first encoding operation. On the basis of the encoded picture of the first picture stream and encoded picture of the second picture stream, dedicated video streams are generated.

摘要： The embodiments of the present invention relates to a method and a processor for representing a 3D scene. In the method, one 3D component of the 3D scene to be represented, captured at least three different views (v1, v2, v3) is projecting to a predefined view (vF). A value associated with each projected view regarding the 3D component is then determined and consistency among the projected views regarding the 3D component is detected. Moreover, a consistency value regarding the 3D component is determined based on the determined values associated with the respective projected view, and the determined values are replaced by the determined consistency value on at least one of the three projected 3D components.

摘要： The invention provides a solution for synchronizing cameras connected via a telecommunication network for capturing a multi-view session controlled by a synchronization module. The synchronization module provides a multi-view capturing parameter determined from capturing parameter received from the at least one camera. Said multi-view capturing parameter is provided to the cameras participating in the session capturing in order to synchronize the capturing of the multi-view session. Further a camera device is proposed which inform the synchronization module about its disposability and about the capturing parameter of the camera. Said camera receives a multi-view capturing parameter which is used for capturing the session.

摘要： Methods and arrangements in video encoding and decoding entities. The methods and arrangements relate to the joint encoding of reference information associated with encoded video. The method and arrangement in a decoding entity relate to obtaining (402) a single syntax element associated with an encoded block Be, and identifying (404) a reference mode and one or more reference pictures based on the obtained syntax element. The method and arrangement further relate to-decoding (406) of the block Be based on the identified reference mode and one or more reference pictures, thus providing a decoded block, B, of pixels.

摘要： A method and apparatus for tuning to a channel of a Moving Pictures Expert Group transport stream (MPEG-TS), for example used in an Internet Protocol Television (IPTV) network, are provided for optimising a channel change procedure. The method comprises the steps of receiving a MPEG transport stream at a first bit rate, the MPEG transport stream comprising a plurality of television channels. Program clock reference (PCR) values are identified in the received MPEG transport stream, and one or more of the program clock reference (PCR) values are adjusted. The MPEG transport stream, including the adjusted program clock reference values, are transmitted at a second bit rate, for example to a receiver device such as a set top box, thereby enabling the set top box to perform a channel change procedure more quickly.

摘要： A scalable video coding method for coding a video sequence (10) results in a bit stream (20} partitionable into two layer representations (201, 2O2) of the video sequence (10). The second layer representation (2O2) has an enhanced resolution compared to the first layer representation (2O1.). The method includes generating (si) predictive coding parameters for the second layer using previously reconstructed pixels (14) in the second layer. The method further includes performing (s2) prediction for the first layer, using the predictive coding parameters and the previously reconstructed pixels (14) in the second layer, to generate a first layer prediction signal. The method further includes generating (s3) a first layer residual, based on the difference between the original image and the first layer prediction signal. The predictive coding parameters and the first layer residual are coded (s4) as the first layer representation (2O1). An encoder (30) and computer program are also provided.
