Embodiment 1

[0424] Record the decoding capability (identified by profile_tier_level) required by the code stream in the video main code stream. At the same time, if the knowledge layer code stream it refers to uses the same decoding method (conforming to the same standard) as the video main code stream, in the video main code stream The decoding capability (identified by profile_tier_level) required by the code stream of the knowledge layer is recorded in the stream.

[0425] On the basis of HEVC or VVC, the decoding capability information required by the code stream of the knowledge layer is put into the vps (video parameters set) of the code stream of the video layer, and the syntax of vps can be as follows.

[0426]

[0427]

[0428] The semantics of the newly added syntax elements are:

[0429] vps_library_picture_enable_flag (also called knowledge image reference flag): 1-bit identifier. When the value is 1, it means that the current code stream (or called the current video la...

Embodiment 2

[0444] On the basis of HEVC or VVC, the decoding capability information required by the code stream of the knowledge layer is put into the sps (sequence parameters set) of the code stream of the video layer, and the syntax of sps is as follows.

[0445]

[0446] The semantics of the newly added syntax elements are:

[0447] sps_library_picture_enable_flag (also called knowledge picture reference flag): 1-bit identifier. When the value is 1, it means that the current code stream refers to the external knowledge code stream; when the value is 0, it means that the current code stream does not refer to the knowledge code stream.

[0448] sps_library_same_standard_flag (may also be referred to as the same standard flag): a 1-bit identifier. When the value is 1, it means that the external knowledge code stream referenced by the current code stream conforms to the same codec standard as the current code stream; when the value is 0, it means that the external knowledge code stream...

Embodiment 3

[0461] On the basis of AVS3, the decoding capability information required by the code stream of the knowledge layer is put into the sequence header (sequence header) of the code stream of the video layer, and the syntax of the sequence header is as follows.

[0462]

[0463] The semantics of the newly added syntax elements are:

[0464]library_picture_enable_flag (also called knowledge image reference flag): 1-bit identifier. When the value is 1, it means that the current code stream refers to the external knowledge code stream; when the value is 0, it means that the current code stream does not refer to the knowledge code stream. (this identifier already exists in AVS3)

[0465] library_same_standard_flag (also called the same standard flag): a 1-bit identifier. When the value is 1, it means that the external knowledge code stream referenced by the current code stream conforms to the same codec standard as the current code stream; when the value is 0, it means that the e...

Abstract

The invention discloses a video coding method, a video decoding method, a video decoding device, video decoding equipment and a storage medium. The method comprises the steps: analyzing a first identification from a video code stream under the condition that the video code stream is allowed to be decoded by referring to a knowledge image corresponding to the knowledge image code stream; under thecondition that the value of the first identifier is a first value, taking the value of a target parameter of the video code stream as the value of the target parameter of a knowledge image code streamreferenced by the video code stream; according to the value of the target parameter of the knowledge image code stream referenced by the video code stream and the knowledge image code stream referenced by the video code stream, reconstructing to obtain a knowledge image corresponding to the knowledge image code stream referenced by the video code stream. According to the method disclosed in the technical scheme provided by the invention, the decoding is relatively flexible, and the decoding efficiency is high.

Description

[0001] This application claims priority to a Chinese patent application with application number 201910018725.6 and titled "Video Encoder, Video Decoder and Corresponding Method" filed on January 8, 2019, the entire contents of which are incorporated by reference in this application . technical field [0002] The present application relates to the technical field of encoding and decoding, and in particular, relates to a video decoding method, a video encoding method, a device, a device, and a storage medium. Background technique [0003] With the development of video coding and decoding technology, there are more and more methods for video coding and decoding, and the coding and decoding method based on knowledge base is one of them. Wherein, after the encoding end encodes the video, a knowledge image code stream and a video code stream referring to the knowledge image code stream will be obtained. Correspondingly, the decoding end needs to decode the knowledge image code st...
