摘要: A prediction direction difference calculating unit derives a prediction direction difference in intra prediction modes of a plurality of reference blocks used for an intra prediction processing of a block to be coded. A most probable mode determining unit and a coding tree selecting unit determine a most probable mode as an intra prediction mode candidate of the block to be coded based on the intra prediction modes of the reference blocks used for deriving the prediction direction difference and the prediction direction difference, and creates a coding tree assigned with a bit stream having a shorter code length than other prediction modes for the determined most probable mode. A variable length coding unit codes information for specifying an intra prediction mode of the block to be coded according to the coding tree.

摘要: A normal frame rate of image data and a high frame rate of image data are favorably transported.A base stream including, as an access unit, encoded image data per picture in a base frame rate of image data acquired by performing blending processing in units of temporally successive two pictures in the high frame rate of image data, is acquired and additionally an enhanced stream including, as an access unit, encoded image data per picture in the high frame rate of image data, is acquired. A container in a predetermined format is transmitted, the container including the base stream and the enhanced stream.

摘要: Disclosed are various embodiments for adjusting the encoding of a video signal into a video stream based on user attention. A first portion of a first video frame is encoded at a lower quality level than a second portion of the first video frame based, at least in part, on a rate of change of objects portrayed in the second portion. The first and second encoded portions are displayed in a second video frame.

摘要: An image capture device can include one or more image sensors and one or more image processors. The image sensor(s) can be configured to detect incoming light provided incident to a surface of each image sensor, each image sensor configured to provide full image frames of image capture data at a first resolution. The image processor(s) can be coupled to the image sensor(s) and configured to receive the image capture data at the first resolution, downsample the image capture data outside one or more regions of interest, and provide a digital image output having a second resolution within the one or more regions of interest and a third resolution outside the one or more regions of interest, wherein the third resolution is less than the second resolution.

摘要: A constrained variable rate coding technique limits the number of bits used in an encoding process. A quality setting indicates a maximum level of quality to be used in the encoding process which limits the number of bits used in the encoding process. A bandwidth reclamation factor which indicates an amount of bandwidth to conserve may also be used with the quality setting. The constrained variable rate coding technique using a lower quality encoding process for less complex video data and a higher quality encoding technique for higher quality video data.

摘要: A method includes intra-refresh encoding each picture of a first set of pictures such that a position of a refresh region for the picture is spatially shifted relative to the position of the refresh region for a previous picture of the first set responsive to determining global motion associated with the first does not exceed a specified threshold. The method further includes intra-refresh encoding each picture of a second set of pictures such that a position of a refresh region for each picture of the second set is fixed to be immediately adjacent to a picture edge that is in a direction of global motion associated with the second set responsive to determining the global motion associated with the second set exceeds the specified threshold.

摘要: In one embodiment, a method for encoding sample adaptive offset (SAO) values in a video encoding process is provided, the method comprising: selecting an edge offset type; selecting one of one or more edge offset sub-classes; within at least one of the edge offset sub-classes, generating an interpolated pixel value that is related to a current pixel value; generating an offset value that is related to the interpolated pixel value; and optionally applying the offset value to at least the current pixel value to form an SAO compensated value.

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