摘要： Multi-view media data is generated by providing encoded media data representative of multiple media views of a media content. Each of the media views (22-28) is associated with a structural priority identifier (36) indicative of an encoding inter-relationship of the media data relative media data of at least another media view(24-28). A content priority identifier (38) is determined for preferably each media view(22-28). The content priority identifier (38) is, in contrast to the structural priority identifier(36), indicative of the rendering importance level of the media data of the media view(22-28). The determination and inclusion of the content priority identifiers(38) provides an improved processing of the media data, for instance in connection with a selective pruning, rendering, and/or protection application of the multi-view media data.

摘要： The embodiments use prediction weights in connection with predictive encoding and decoding of a depth map in the form of a frame (10) with pixels (11) having pixel values representing distances between a camera (40) and objects. The prediction weight is calculated based on depth clipping plane parameter values associated with the frame (10) and with a reference frame (20, 30) based on which pixels of the frame (10) are encoded and decoded. Using depth clipping plane parameter values when calculating prediction weights, improves coding efficiency of depth map coding and decoding.

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.

A content priority identifier (38) is determined for preferably each media view(22-28).
