    摘要: A method is proposed for coding an omnidirectional video into a bitstream, at least one picture of the omnidirectional video being represented as a surface, the surface being projected onto at least one 2D picture using a projection function. Such method comprises, for at least one current block of the at least one 2D picture: adapting (S2400) a size of the at least one current block as a function of a pixel density function determined according to the projection function; and encoding (S2410) the at least one current block into the bitstream using the adapted size.

    摘要: The moving picture coding apparatus includes a motion compensation coding unit (107) for deciding a coding mode for coding a current block to be coded and for generating predictive image data based on the coding mode; and a direct mode enable/disable judgment unit (109) for judging whether or not scaling processing can be performed when the coding mode decided by the motion compensation coding unit (107) is a temporal direct mode. When it is judged that the scaling processing cannot be performed, the motion compensation coding unit (107) performs motion compensation either by using another coding mode or without the scaling processing.

    摘要: Methods, apparatus, and systems for video coding/decoding are disclosed. One representative method includes a decoder receiving video content including at least a base layer (BL), an enhancement layer (EL) and phase information. The phase information includes an indicator indicating one or more sets of phase parameters from among plural sets of phase parameters. The method further includes assembling the BL into an inter-layer reference (ILR) picture based on the video content and the received phase information, selecting one or both of the ILR picture or an EL reference picture, and predicting a current EL picture using the phase information and one or more of the selected ILR picture or the selected EL reference picture.
