Abstract: The present disclosure describes techniques for coding video data in a manner that provides consistency to portions of the video that have similar content. According to such techniques, a video sequence may be parsed into partitions and content of the partitions may be analyzed. Partitions may be grouped together based on detected similarities in content. Coding parameters may be selected for each partition based on the partition's membership in the groups. Thus, when the video sequence is coded, coding parameters for frames of two commonly-grouped partitions may be similar, which causes coded video data to have similar presentation.

Abstract: Methods of in-loop deblocking filter for high dynamic range (HDR) video compression are disclosed. HDR processing and standard dynamic range (SDR) processing adopt different electro-optical transfer function (EOTF) to convert digital code words to linear luminance. For compressing HDR video, EOTF is proposed to be involved in the selection of two deblocking parameters, ? and tC, which control the strength of deblocking filter. In local activity checking for filter decisions, the calculated local signal characteristics and the thresholds are adjusted according to EOTF. After deblocking filter, the clipping range is modified based on EOTF. The chroma deblocking filter is also extended to inter-inter block boundary.

Abstract: Methods of sample adaptive offset (SAO) for high dynamic range (HDR) video compression are disclosed. For band offset (BO), the sample range of each component is unequally divided into a number of bands based on the distribution of samples, the electro-optical transfer function (EOTF) of HDR source and one perceptually uniform EOTF. Each component may have a different number of bands, different number of signaled bands, and different range value for signaled offsets in BO mode. For edge offset (EO), Cb and Cr may use separate syntax elements. In the sample classification for EO, the difference between the current sample and its neighbor is compared with a threshold to determine whether it is a local valley, a local peak, or corners. A distortion measure for HDR source images are also disclosed.

Abstract: Techniques are disclosed for coding high dynamic range (HDR) data. According to such techniques, HDR data may be converted to a domain of uniform luminance data. The uniform domain data may be coded by motion compensated predictive coding. The HDR data also may be coded by motion compensated predictive coding, using a coding parameter that is derived from a counterpart coding parameter of the coding of the uniform domain data. In another technique, HDR data may be coded using coding parameters that are derived from HDR domain processing but distortion measurements may be performed in a uniform domain.

Abstract: Techniques are disclosed for selecting deblocking filter parameters in a video decoding system. According to these techniques, a boundary strength parameter may be determined based, at least in part, on a bit depth of decoded video data. Activity of a pair of decoded pixel blocks may be classified based, at least in part, on the determined boundary strength parameter, and when a level of activity indicates that deblocking filtering is to be applied to the pair of pixel blocks, pixel block content at a boundary between the pair of pixel blocks may be filtered using filtering parameters derived at least in part based on the bit depth of the decoded video data. The filtering parameters may decrease strength with increasing bit depth of the decoded video data, which improves quality of the decoded video data.

Abstract: Techniques are disclosed by which a coding parameter is determined to encode video data resulting in encoded video data possessing a highest possible video quality. Features may be extracted from an input video sequence. The extracted features may be compared to features described in a model of coding parameters generated by a machine learning algorithm from reviews of previously-coded videos, extracted features of the previously-coded videos, and coding parameters of the previously-coded videos. When a match is detected between the extracted features of the input video sequence and extracted features represented in the model, a determination may be made as to whether coding parameters that correspond to the matching extracted feature correspond to a tier of service to which the input video sequence is to be coded.

Abstract: Embodiments of the present disclosure provide techniques for environment aware supervised HDR tone mapping. According to those techniques, responsive to metadata provided with HDR source video data, the received metadata may be compared to sensor date representing viewing conditions at a display device. Tone mapping corrections to the HDR source video data may be derived from the comparison of the received metadata to the sensor data. The HDR source video data may be altered based on the tone mapping corrections. The altered HDR source video data may be used to drive the display device.
