Abstract

A decoding method includes receiving a code stream including multiple layers and a video parameter set (VPS), where the VPS includes a direct reference layer flag, the direct reference layer flag being equal to a first value indicating that a second layer is not a direct reference layer of the first layer, the direct reference layer flag being equal to a second value indicating that the second layer is a direct reference layer of the first layer; deriving a reference layer flag by: initially setting the reference layer flag to the first value; when the direct reference layer flag has the second value, updating the reference layer flag to the second value; and decoding the image in the first layer according to the reference layer mark to obtain a decoded image.

Description

[0001] Related Application Cross Reference [0002] This patent application claims the benefit of Wang Yekui's U.S. Provisional Patent Application No. 62 / 911,808, titled "Scalability In Video Coding," filed on October 7, 2019, the content of which Incorporated in this application by reference. technical field [0003] This disclosure generally describes techniques for multi-layer video codestreams in video coding. More specifically, the present disclosure describes techniques for reducing redundancy when indicating layer-corresponding parameters in a multi-layer codestream in video coding. Background technique [0004] Even relatively short videos require large amounts of video data to describe, which can create difficulties when the data is to be streamed or otherwise transmitted over communication networks with limited bandwidth capacity. Therefore, video data is usually compressed before being transmitted over modern telecommunications networks. Since memory resources ...
