Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0028] Embodiments of the present invention will be described from the following aspects, and the specific technical solution mainly includes several parts as a whole:

[0029] 1. In the main chip of the TV’s core board, build a seamless source-changing driver architecture for switching signal sources and application scenarios. The architecture considers supporting the design of various multi-channel, multi-scenario, and standard software platforms during construction Mode, the core of which is a series of signal processing processes, including framing, screening, data saving, image signal processing of the next scene or channel, and replaying of the last frame of the TV when the signal channel is switched or when the application is switched. The specific methods include the following main contents:

Abstract

The invention discloses a seamless switchover system and a method of an application scene and a channel. The method comprises the steps of analyzing and judging processing of a use scene switchover request, pre-judging whether to carry out source change or scene switchover, selecting a display frame processing the current signal channel, storing image data of a selected content in a memory, loading the image data stored in the memory into a display channel for displaying, switching the content displayed in the display channel to the actual use scene according to control time and a signal condition of the switched channel, and displaying the last frame of the former display channel all the time in a switchover process to achieve the instant scene switchover with a natural visual effect. According to the seamless switchover system and the method of the application scene and the channel, the operation experience in the switchover of signal sources, the signal channel and the application scene on an intelligent television set can be greatly improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a system and method for seamless switching of application scenarios and channels. Background technique [0002] With the popularity of Android smart flat-panel TVs, the experience of flat-panel TVs in terms of vision, hearing and operation has become the main indicator pursued by consumers. After entering 2014, the high-end chip-level processing capability of quad-core CPU&GPU has gradually become the mainstream high-end product of flat-panel TV. With the continuous improvement of the performance of the movement, the user's sense of experience and awareness of the TV are constantly improving. Generally, when changing the signal source or switching the application scene, a TV set adopts a black screen, or inserts a picture, or inserts an animation effect, but these methods cannot achieve a natural and smooth transitional visual effect.
