Abstract

The invention discloses a video definition adjustment method and device. The video definition adjustment method comprises the following steps: when playing video, acquiring average loading speed of the video and playing speed of the video in a preset time period; detecting definition when the video is played; when the definition is high, if the average loading speed is not greater than the playing speed, acquiring a first video loading value, namely a video loading value during high definition; and based on the first video loading value, adjusting video loading definition. According to the embodiment of the invention, the average loading speed of the video, the playing speed of the video and the video loading value are analyzed, so that automatic adjustment of the video loading definition is realized, and operation efficiency is greatly improved compared with an existing way that the definition needs to be switched manually by a user; meanwhile, the condition that the video is suddenly stuck and paused in a playing process is avoided, and video playing effect is improved.

Description

technical field [0001] The invention belongs to the technical field of video signal processing, and in particular relates to a video definition adjustment method and device. Background technique [0002] With the rapid development of electronic technology, people can watch online videos through various smart terminals such as tablet computers and mobile phones. With the popularization of wireless fidelity (WiFi, WIreless-FIdelity), most people watch online videos online, watching while loading. This method is often affected by network conditions. HD playback is performed when network conditions are good, and standard-definition or normal-definition playback is performed when network speed is poor. [0003] During the research and practice of the prior art, the inventor of the present invention found that when the network condition is good at the beginning, the video will be played in high-definition, and the network becomes worse during the playback, resulting in a sudden f...
