Abstract

The invention relates to a picture display method and device, a set top box and a computer readable storage medium, and relates to the technical field of image processing. The method comprises the steps of judging whether a graphic cache of an obtained target picture is marked as being output through a video layer module of a display system or not; under the condition that the graphic cache is marked as being output through the video layer module, generating a video Surface and a plurality of graphic Surfaces with the same content according to the graphic cache; and sending the video Surface and the plurality of graphic Surfaces to a video layer module, so that the video layer module mixes the video Surface and the plurality of graphic Surfaces into a target video and outputs the target video. According to the technical scheme, the picture display definition can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a picture display method, a picture device, a set-top box, and a computer-readable storage medium. Background technique [0002] An IPTV (Interactive Personality Television, Interactive Network Television) set-top box completes video processing and presentation through video decoding and playback. [0003] In related technologies, the set-top box completes the processing and presentation of pictures through a GPU (Graphics Processing Unit, graphics processing unit) and a browser. Contents of the invention [0004] The inventors of the present disclosure have discovered the following problem in the above-mentioned related technologies: limited by the processing capability of the GPU, it is impossible to truly present pictures with a resolution higher than 1080P. Therefore, for pictures with 4K ultra-high-definition resolution, even on a 4K ultra-high-defin...
