An image encoding/decoding method and apparatus are provided. An image decoding method according to the present disclosure includes: receiving an image, in which a first atlas for a basic view of a current image and a second atlas for an additional view of the current image are merged; extracting an image divided in a predetermined image unit within the first atlas and the second atlas; dividing the first atlas and the second atlas in the predetermined image unit; and reconstructing the image divided in the predetermined image unit, wherein the dividing of the first atlas and the second atlas in the predetermined image unit may non-uniformly divide the first atlas and the second atlas.

Method and apparatus for immersive video encoding and decoding

Methods and systems are disclosed for a mobile device to decode video based on available power and/or energy. For example, the mobile device may receive a media description file (MDF) from for a video stream from a video server. The MDF may include complexity information associated with a plurality of video segments. The complexity information may be related to the amount of processing power to be utilized for decoding the segment at the mobile device. The mobile device may determine at least one power metric for the mobile device. The mobile device may determine a first complexity level to be requested for a first video segment based on the complexity information from the MDF and the power metric. The mobile device may dynamically alter the decoding process to save energy based on the detected power/energy level.

Power aware video decoding and streaming

A video transmission method according to embodiments comprises: a pre-processing step for processing video data; a step for encoding the video data; and/or a step for transmitting a bitstream including the video data. A video reception method according to embodiments comprises the steps of: receiving video data; decoding the video data; and/or rendering the video data.

360 video transmission method, 360 video reception method, 360 video transmission apparatus, and 360 video reception apparatus

Systems, methods, and instrumentalities are provided to implement video coding system (VCS). The VCS may be configured to receive a video signal, which may include one or more layers (e.g., a base layer (BL) and/or one or more enhancement layers (ELs)). The VCS may be configured to process a BL picture into an inter-layer reference (ILR) picture, e.g., using picture level inter-layer prediction process. The VCS may be configured to select one or both of the processed ILR picture or an enhancement layer (EL) reference picture. The selected reference picture(s) may comprise one of the EL reference picture, or the ILR picture. The VCS may be configured to predict a current EL picture using one or more of the selected ILR picture or the EL reference picture. The VCS may be configured to store the processed ILR picture in an EL decoded picture buffer (DPB).

Codec architecture for multiple layer video coding

Provided are a method and an apparatus for streaming a multi-view 360 degree video, and a method for streaming a 360 degree video according to an embodiment of the present disclosure includes: encoding a multi-view video to a bitstream of a base layer and a bitstream of a tile layer constituted by at least one tile; selecting a tile included in a user view video in the encoded bitstream of the tile layer by using user view information received from a 360 degree video rendering apparatus, and video information of the multi-view video; extracting tile data included in the selected user view video from the encoded bitstream of the tile layer, and generating a tile bitstream corresponding to the extracted tile data; and transmitting the encoded bitstream of the base layer and the generated tile bitstream to the 360 degree video rendering apparatus.

Method and apparatus for streaming multi-view 360 degree video

Methods, systems, and instrumentalities are described to implement single loop decoding, A video decoding device (VDD) may receive a video bitstream, which may include one or more bitstreams (e.g., base layer bitstream, enhanced layer bitstream, etc.) The VDD may generate a hybrid inter-layer reference (H-ILR) picture. The H-ILR picture may be generated based on one or more inputs including, for example, a first layer motion information, a processed (e.g., upsampled) first layer residue signal, a second layer texture information, etc. The first layer motion information may be derived from a compressed first layer motion field or an uncompressed first layer motion field. An H-ILR block of the H-ILR picture may be reconstructed by deriving motion information of the H-ILR block from one or more neighboring H-ILR blocks in the H-ILR picture, for example, when the neighboring blocks are inter-coded.

Single loop decoding based interlayer prediction

An image processing method and an electronic device supporting the method are provided. The electronic device includes a processor having an image processing module processing an input image, and a memory, wherein the processor obtains image data that is processed for the input image, wherein the memory stores volatile information which is temporarily obtained from the image during an image processing process of the image processing module.
