Display device and video playing processing method

By constraining the aspect ratio of the video container and dynamically calculating the target rendering area through the controller, the problems of decreased video display effect and touch failure during video playback on display devices are solved. This achieves the maintenance of the video screen ratio and precise matching of touch operation, thus improving the user experience.

AI Technical Summary

Technical Problem

In display devices, issues such as degraded video display quality and touch malfunction during video playback, especially when the video container exceeds the screen area, result in distorted video aspect ratio, loss of detail, and inability of touch operations to match the screen content, leading to a degraded user experience.

Method used

The controller dynamically calculates the visible area of ​​the video container by constraining its size according to a preset aspect ratio, and determines the target rendering area in the original video coordinate system. This establishes a two-way mapping relationship between the screen coordinate system and the touch coordinate system, ensuring that touch operations are accurately matched with the video screen.

Benefits of technology

Maintain the original aspect ratio of the video frame, avoid irregular pixel compression, solve touch failure issues, and optimize the visual effects of video playback and the touch interaction experience.

Abstract

The invention discloses a display device and a video playing processing method, the display device constrains the aspect size of a video container according to a preset aspect ratio, and in response to the video container exceeding a screen area, mapping an overlapping area of the video container and the screen area to a container coordinate system of the video container, and obtaining a visible area of the video container in the container coordinate system. And keeping the video aspect ratio of the original video based on the constraint of a preset aspect ratio, and converting the visible region to a video coordinate system according to a preset processing strategy to obtain a target rendering region. And rendering a video picture of the target rendering area through the video container, and constructing a bidirectional mapping relationship between the screen coordinate system and the touch coordinate system based on the visible area and the target rendering area so as to respond to a touch event for the target rendering area according to the bidirectional mapping relationship. According to the invention, the aspect ratio of the video can be effectively maintained, the problems of picture ratio imbalance, detail distortion and touch failure during screen exceeding are avoided, and the interactive experience of video playing can be optimized.
