    摘要： A method for decoding a picture block is disclosed. The decoding method comprises: reconstructing reference picture from another reference picture of a decoder picture buffer of a first layer of a multi-layered stream and from data decoded from a second layer of said multi-layered stream and storing said reference picture in a decoder picture buffer of said second layer, wherein said reference picture is indicated as not to be displayed; decoding a flag indicating that a subsequently decoded picture of the second layer is not using any inter-layer prediction; and reconstructing a picture block of said subsequently decoded picture at least from said reference picture.

    摘要： The present disclosure generally relates a method and device for processing color image data. The method comprises a color gamut mapping in the course of which a color image data (CID), represented by a first 2D point (A) belonging to a representation of the original color gamut in a chromaticity diagram, is mapped to a mapped color image data (MCID) of a target color gamut (TCG), the mapped color image data of the target color gamut (TCG) being represented by a second 2D point (B) belonging to a representation of the target color gamut (TCG) in the chromaticity diagram, wherein the color gamut mapping comprises: —obtaining (100) a representation of a preserved color gamut (PCG) in the chromaticity diagram by applying an homothety either to the original color gamut or to the target color gamut; —checking (110) if said first 2D point is located outside the representation of the preserved color gamut (PCG); and —when said first 2D point is located outside the representation of the preserved color gamut (PCG), moving (300) said first 2D point so that it belongs to the representation of the target color gamut (TCG), the second 2D point being then equal to the moved first 2D point. The disclosure relates also to a method and device for encoding/decoding color image data.

    摘要： A method for decoding a picture block is disclosed. The decoding method comprises: decoding decoded data, and information for identifying a reconstructed reference picture in a decoder picture buffer; reconstructing another reference picture from the identified reconstructed reference picture identified by the information and from the decoded data; replacing in the decoder picture buffer the reconstructed reference picture identified by the information with the another reference picture; and reconstructing the picture block from the another reference picture.

    摘要： A method for encoding an interlaced video comprising a sequence of alternating TOP and BOT fields is disclosed. The method for encoding comprises: producing a sequence of frames, each frame being determined from at least two consecutive fields, each field forming a rectangular region of the frame, encoding each frame of the sequence to produce an encoded video of the sequence of frames.
