Video processing method and device

Abstract

The invention discloses a video processing method and device. The method comprises: detecting a received video signal, and judging whether the video signal is a video signal of a preset frame type or not; if yes, determining the range of a to-be-cut frame of each frame of image in the video signal; and cutting and displaying the video signal according to the range of the to-be-cut frame. The adaptive processing of the video signal of the input television is realized, on one hand, the black frame display in the video signal with the black frame input by the set top box is avoided, and on the other hand, the incomplete picture caused by over-cutting is avoided, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video processing method and device. Background technique [0002] At present, there are more and more types of smart set-top boxes on the market, and different set-top boxes process video signals in different ways. Due to the geometric distortion of low-resolution video signal imaging, there will be noise on the edge of the video signal, which will cause interference phenomena such as frame drawing. A certain width of the black border to protect the valid signal. [0003] For the video signal input by the set-top box, some TVs do not process it, which will cause the TV to have a black border when displaying the video signal output by the above-mentioned set-top box, resulting in a narrow and small TV display screen and poor screen display effect, affecting users experience; another processing method is to cut the video signal input to the TV, and this processing method...

Problems solved by technology

Due to the geometric distortion of low-resolution video signal imaging, there will be noise on the edge of the video signal, which will cause interference phenomena such as frame drawing. Black border of certain width to protect valid signal

[0003] For the video signal input by the set-top box, some TVs do not process it, which will cause the TV to have a black border when displaying the video signal output by the above-mentioned set-top box, resulting in a narrow and small TV display screen and poor screen display effect, affecting users experience; another processing method is to cut the video signal input to the TV, and this processing method will cut the video signal input to the TV, and the cutting in the prior art is determined by the resolution of the video signal

Then, for different video signals with the same resolution, the cropping size is the same, which may cause over-cropping or under-cropping. For example, when the black frame output by the set-top box is large, the TV does not completely crop the black frame, and the frame will still exist when displayed. ;When the TV displays the video signal output by the computer connected via HDMI, the TV screen will not be fully displayed because the video signal output by the computer does not have a black frame and the TV will cut it.
