Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] Since the bandwidth of the display processing module in the front-end SOC is limited to 300MHz (the processing capability of the SOC is limited), it can only support up to 4K×2K@30Hz, so it cannot meet the resolution and display adaptation requirements of the signal with a higher frame rate of 60Hz , for this kind of high frame rate or bit ...

Abstract

The invention provides a video playing processing method and a device. The method comprises the steps: a decoded video image corresponding to a to-be-played video is acquired; when a first resolution scheme of the video image does not match with a second resolution scheme, the first resolution scheme of the video image is converted into the second resolution scheme; according to the first resolution scheme of the video image acquired in advance, the resolution scheme of the video image converted into the second resolution scheme is converted into a third resolution scheme matching with a display screen; wherein the video image converted into the second resolution scheme comprises effective pixel points and non-effective pixel points; and the effective pixel points is the pixel points in the video image before converted. According to the invention, the blank screen problem caused by the resolution change in playing process can be avoided.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a video playback processing method and device. Background technique [0002] With the development of television technology, more and more users use televisions as terminal devices for watching videos. When users use a TV to perform video on demand, they often encounter problems such as freezes, black screens, or delays during video playback due to changes in network speed. [0003] figure 1 It is a schematic diagram of the existing video playback processing flow. For the most commonly used video signal with a frame rate of 30Hz, due to the problem of real-time changes in network bandwidth, in order to cope with changes in network bandwidth, for the same video program, some background servers of video playback websites will have 480P / 720P / For signal sources with various resolutions such as 1080I / 1080P / 2160P, during the video playback process, the background se...
