Video display method and system for television terminal

Abstract

The invention discloses a video display method and system for a television terminal. The video display method for the television terminal comprises the steps of decoding video information of a current video when a video player of the television terminal receives a video URL address sent by a mobile terminal and obtaining an angle of the current video needing to be rotated; rotating the current video by the television terminal according to the rotation angle, thereby obtaining the rotated video; calling an algorithm to set a size of a video display area by the television terminal and controlling the video player to display the rotated video in the video display area of which the size is adjusted. According to the video display method for the television terminal provided by the invention, the problem that the played image is stretched to deform when the length and width of the image of a current video file do not correspond to the length and width of a smart television can be solved, the playing quality of the player is improved, moreover, scaling is calculated in a display layer, complicated video frame operation is avoided, and the blurred screen, black screen and delay phenomena are effectively prevented from appearing in the smart terminal.

Description

technical field [0001] The present invention relates to the field of television terminals, in particular to a video display method and system for a television terminal. Background technique [0002] Realize video rotation on the mobile phone. Because the width and height of the mobile phone are fixed, the horizontal and vertical screen switching can be realized through the Android native solution. Currently, the video on the mobile phone can be pushed to the TV for playback through the multi-screen interactive protocol. When the online video is pushed to the TV, The push video will be displayed horizontally, which is realized by hardware decoding and does not need to be rotated and stretched. However, mobile phone shooting video can be divided into two shooting modes: horizontal shooting and vertical shooting. The aspect ratio of the video after shooting does not correspond to that of the TV. Scaling appears to be stretched after rotation. [0003] In addition, currently o...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a video display method and system for a TV terminal in view of the above-mentioned defects of the prior art, so as to solve the problem of video display ratio and smart TV when the video recorded by the mobile phone is currently pushed to the smart TV for display. The TV does not match, causing the video to be stretched and deformed; when using software decoding, due to the complex scaling algorithm, the CPU of the smart TV is seriously consumed, and problems such as blurred screen, black screen and freeze are prone to occur
