Embodiment Construction

[0032] Before introducing and explaining the embodiment of the method of the present application, first combine figure 1 A brief introduction to video coding technology. Please refer to figure 1 , which shows a basic flowchart of a video encoding process provided by an embodiment of the present application.

[0033] A video signal refers to a sequence of images comprising a plurality of frames. A frame is a representation of the spatial information of a video signal. Taking the YUV mode as an example, a frame includes a luma sample matrix (Y) and two chrominance sample matrices (Cb and Cr). From the perspective of the acquisition method of the video signal, it can be divided into two methods: the one captured by the camera and the one generated by the computer. Due to different statistical characteristics, the corresponding compression coding methods may also be different.

[0034] In some mainstream video coding technologies, such as H.265 / HEVC, H.266 / VVC (Versatile Vide...

Abstract

The invention discloses a video coding method, a device, equipment and a product, and relates to the technical field of video coding and decoding. The method comprises the following steps: acquiring gradient information and brightness information of a to-be-coded unit; when the gradient information accords with a first condition or the brightness information accords with a second condition, cancelling the intra-frame search operation for the to-be-coded unit; and under the condition that the intra-frame search operation is cancelled, performing coding processing on the to-be-coded unit to obtain coding information of the to-be-coded unit. In the technical scheme provided by the embodiment of the invention, whether gradient information of a to-be-coded unit meets a first condition or not is judged, and whether pixel value difference information corresponding to every two of at least two sub-coding units in the to-be-coded unit meets a second condition or not is judged; whether the intra-frame search operation corresponding to the intra-frame block copy coding mode is skipped or not is determined through the intra-frame block copy coding mode, complex search operation on a coding unit with simple texture information is avoided, and therefore the video coding speed and the video coding efficiency are improved.

Description

technical field [0001] The present application relates to the technical field of video encoding and decoding, and in particular to a video encoding method, device, equipment and product. Background technique [0002] Screen video is a video obtained by intercepting the screen content of electronic devices such as computers and mobile phones. Screen video is widely used in video conferencing, online education, remote desktop and other scenarios. [0003] In current video codec standards, such as HEVC (High Efficiency Video Coding, High Efficiency Video Coding), an IBC (Intra Block Copy, Intra Block Copy) prediction technology is introduced for SCC (Screen Content Coding, Screen Content Coding). [0004] Due to the addition of new IBC coding tools, the complexity of video coding increases and the coding efficiency is low. Contents of the invention [0005] Embodiments of the present application provide a video coding method, device, device, and product, which can reduce the...
