摘要： Embodiments of the present invention disclose a method and an apparatus for detecting frame types. The method includes: detecting play time of each frame; and if the play time of a current frame is less than the maximum play time of received frames, determining the current frame as a bi-directional predicted frame, B-frame. In the technical solutions provided by the embodiments of the present invention, the frame types are determined according to a coding sequence of various frames and comparison between data amounts of various frames received earlier and later, without decoding a payload. Therefore the impact of a reduction factor is eliminated and the frame types can be detected more accurately.

摘要： The present invention relates to an image processing apparatus and method that can generate a high-accuracy prediction image with a small amount of control information. A motion compensation circuit (51) specifies a macroblock corresponding to a prediction image in a reference frame other than a current frame using a motion vector supplied from a prediction mode determination circuit (41). The motion compensation circuit (51) reads an image of the specified macroblock from a frame memory (19), and extracts the read image as a motion compensation image. An intra-prediction circuit (52) performs intra-prediction on the current frame using an arbitrary method to generate an intra-prediction image IP. The present invention can be applied to, for example, an encoding apparatus and a decoding apparatus.

摘要： The inventors realized that representing HDR content using LDR content and HDR residual is not unproblematic. The invention therefore proposes representing HDR content using LDR content, LDR residual and global illumination data, instead.
That is, it is proposed a method of encoding an HDR video of high dynamic range together with an LDR video, the LDR video providing a lower dynamic range depiction of the HDR video content, the method comprising using processing means for encoding one video of the LDR video and a further LDR video extracted from the HDR video independent from the other video of the LDR video and the HDR video and predictive encoding the other video using the one video as reference, and lossless encoding global illumination data further extracted from the HDR video.
This has the advantage that prediction is more stable and globally optimal predictors are more easily found.

摘要： The present invention relates to an encoding device, an encoding method, a decoding device, and a decoding method capable of encoding and decoding multi-viewpoint images in accordance with a mode that is compatible with an existing mode.
A compatible encoder generates a compatible stream by encoding an image A 1 that is a compatible image in units of access units. An auxiliary encoder generates an encoded stream of a multiplexed image of auxiliary images by encoding a multiplexed image of images B1 and C 1 that are auxiliary images used when multi-viewpoint images are generated from the compatible image in units of access units. A multiplexing unit transmits the compatible stream, a 3DV Representation Delimiter representing a boundary of a unit, and an encoded stream of the multiplexed image of the auxiliary images. The present technology can be applied to, for example, an encoding device that encodes a 3D image of the multi-viewpoint mode.

摘要： A method and system are described for preparing a batch 15 of data sets 1-11 for a batch processing using a predetermined correlation encoding operation. In a first step, the batch 15 of data sets 1-15 is analysed to determine a plurality of correlation parameters 22 representing degrees of correlation between member data sets 1-11 of said batch 15 of data sets 1-11. In a second step, the correlation parameters 22 are used to generate an optimized correlation dependency graph 16 of the member sets 1-11 for performing the predetermined correlation encoding operation. By optimizing the correlation dependencies between data sets for subsequent processing, e.g. data compression, of the data sets, the advantages of correlation encoding can be used, even for data sets which appear a priori to be unordered and only weakly correlated.
