A method of encoding video including: writing a plurality of predetermined buffer descriptions into a sequence parameter set of a coded video bitstream; writing a plurality of updating parameters into a slice header of the coded video bitstream for selecting and modifying one buffer description out of the plurality of buffer descriptions; and encoding a slice into the coded video bitstream using the slice header and the modified buffer description.

An image encoding method is used for encoding a current picture on a block-by-block basis and includes: generating a reference picture list by (i) assigning a reference picture index to a reference picture referable for encoding the current picture and (ii) including the reference picture assigned the reference picture index into the reference picture list; and encoding a current block included in the current picture with reference to a reference picture that is specified, from the reference picture list, for encoding the current block, wherein, when a reference picture belonging to a reference view different from a current view to which the current picture belongs has a chance of being referenced for encoding the current picture, the reference picture belonging to the reference view is added to the reference picture list in the generating.

Sample adaptive offset (SAO) in accordance with video coding. SAO filtering may be performed before de-blocking processing (e.g., in accordance with video signal decoding and/or encoding). For example, a receiver and/or decoder communication device may receive signaling from a transmitter and/or encoder communication device that includes various band offsets.

Corresponding band indices may be determined via analysis of the received video signal (e.g., received from the transmitter and/or encoder communication device), inferentially without requiring signaling of such band indices from the transmitter and/or encoder communication device. Upon appropriate analysis of one or more largest coding units (LCUs) generated from the video signal to determine a pixel value distribution (e.g., which may be using a histogram in one instance), then based on that pixel value distribution, the band indices are identified and the band offsets applied thereto.

In one embodiment, a method includes receiving multimedia content information associated with at least one segment of a multimedia content, receiving a request to view the at least one segment of the multimedia content from a client device, logging playback information associated with the viewing of the at least one segment of the multimedia content, determining a multimedia quality metric associated with the at least one segment of multimedia content based in part upon a portion of the received multimedia content information and a portion of the logged playback information, and classifying the at least one segment of the multimedia content with the multimedia quality metric.

A video coder includes a processing resource and a non-transitory storage device containing instructions executable by the processing resource to compute a weighted frame based on a saliency map and a frame. The saliency map is to indicate the relative importance of each pixel in a current frame based on its perceptual significance. The frame is to include differences between corresponding pixels in a current frame and a motion predicted frame.

A method for encoding a raw lenselet image includes a receiving phase, wherein at least a portion of a raw lenselet image is received, the image including a plurality of macro-pixels, each macro-pixel having pixels corresponding to a specific view angle for the same point of a scene, and an output phase, wherein a bitstream having at least a portion of an encoded lenselet image is outputted. The method has an image transform phase, wherein the pixels of said raw lenselet image are spatially displaced in a transformed multi-color image having a larger number of columns and rows with respect to the received raw lenselet image, wherein dummy pixels having undefined value are inserted into the raw lenselet image and wherein the displacement is performed so as to put the estimated center location of each macro-pixel onto integer pixel locations. Moreover, the method includes a sub-view generation phase, wherein a sequence of sub-views is generated, said sub-views having pixels of the same angular coordinates extracted from different macro-pixels of the transformed raw lenselet image. Finally, the method has a graph coding phase, wherein a bitstream is generated by encoding a graph representation of at least one of the sub-views of the sequence according to a predefined graph signal processing technique.
