Benefits of technology

[0012]Another aspect of the present disclosure is directed to a non-transitory computer-readable storage medium storing a set of instructions. The instructions, when executed by one or more processors, cause the one or more processors to perform a method of video encoding. The method of video encoding includes: receiving a source video frame, dividing the source video frame into a coding tree unit, dete...

Problems solved by technology

However, evaluating whether to enable ACT, requires an additional rate distortion optimization (RDO) check during encoding, where the RDO check evaluates a rate distortion (RD) cost of the coding mode with enabled ACT.
Such ...

Embodiment Construction

[0022]Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying′drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of systems and methods consistent with aspects related to the disclosure as recited in the appended claims.

[0023]FIGS. 1A-1J illustrate a video frame and related partitions of the video frame according to embodiments of the present disclosure.

[0024]FIG. 1A shows a video frame 101 that includes a number of pixels located at locations within the video frame. Video frame 101 is partitioned into coding tree units (CTUs) 102. Each CTU 102 is sized according to L vertical samples by L horizontal sam...

Abstract

A video encoding method includes receiving a source video frame, dividing the source video frame into a coding tree unit, determining a coding unit from the coding tree unit, determining a correlation between components of the coding unit, enabling or disabling a coding mode of the coding unit, determining whether to evaluate a size of a transform unit for an enabled coding mode, and determining a transform unit of the coding unit for the enabled coding mode, wherein the size of the coding unit is defined by a number (N) of samples.

Description

RELATED APPLICATIONS[0001]This application is based upon and claims the benefit of U.S. Provisional Patent Application No. 62 / 172,256, filed Jun. 8, 2015, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD[0002]This disclosure generally relates to methods and systems for video encoding and decoding.BACKGROUND[0003]The demand for high quality video continually increases. With the advent of 4K and 8K video formats that require the processing of large amounts of video data, improvements to video encoding and decoding efficiency in the compression of such video data are needed. Furthermore, consumers expect the transmission and reception of high quality video across various transmission mediums. For example, consumers expect high quality video obtained over a network for viewing on portable devices, such as smartphones, tablets, and laptops, as well as on home televisions and computers. Consumers also expect high quality video for display during teleconfer...
