Description

  The present invention relates to video signal processing, and more particularly to a video signal processing system and method for application in a video environment, selecting a local area or all of contents displayed on a display screen, and selecting the selected screen contents. This process is performed to meet the user's request.

  The main video technologies typically used on displays, digital television, include video primary format conversion, video scaling, and video secondary format conversion. The display interface first converts the primary format to a raw video data format for the received video signal format to facilitate subsequent scaling processing. The scaling process converts the input pixel format of the low display input signal to the display's native pixel format, ie sets the pixel format to the native level. . Finally, the low-video data format signal after the scaling process is converted into an interface form and an image display format suitable for a display screen by secondary format conversion. In conventional applications, the computer's own graphics system must first convert the video signal to the required format conversion, scaling, or other process before transmitting the associated video signal to the display for display. Special video processing, such as zooming, mirroring, rotation, etc.

  The video scaling device in the display includes a video signal processing module and associated video data buffer. The primary format converter first converts the format of the input video signal to a raw video data format and transmits it to the video data buffer of the video scaling device. The video signal processing module of the video scaling device The raw video data stored in the biosignal data buffer is scaled to meet the demand for a display screen with a specific fixed pixel format. The raw video data after the scaling process is transmitted to a video secondary format converter, converted into one specific signal format, and transmitted to a display screen having a specific interface form for display.

  In general, the video scaling includes two types of line video scalar and panoramic video scalar. Among them, the linear video scaling is distributed only on the individual horizontal display lines in the vertical direction, and smoothly smooths or compresses the raw video data. At the request of the panoramic video scaling process, duplicate or erase is performed on the continuous horizontal display lines to match the specific fixed pixel format required by the panoramic video represented on the display screen. Based on the two-dimensional video processing principle for panoramic video scaling, smooth and extended low-compressed video data processing in the horizontal and vertical directions is integrated into a kind of high technology, quality grade video processing.

  A relatively large video data buffer is expensive for panoramic video scaling. Linear video scaling or panoramic video scaling requires a relatively small memory linear video data buffer or a relatively large memory screen video data buffer, respectively. Furthermore, since panoramic video scaling requires extension and / or compression processing on the video signal in the horizontal and vertical directions, it is relative to the video signal processing module in linear video scaling and in the panoramic video scaling processing. The video signal processing module has processing functions and complexity.

  In addition to the video signal channel, the display interface usually includes a so-called display data channel DDC (Display-Data-Channel) or other serial communication interface SCI (Serial Communication Interface). The display system retrieves the identification capability of the display model through the display data channel or other serial communication interface, or sets the display operation module, characteristics, and the like.

  The video scaling device having the internal fixed display module, which is the above-mentioned publicly known technology, is based on the fixed-width high pixel point number and proportionality of the internal display screen in the linear or panoramic view scaling technology direction. The entire video signal can be automatically extended and / or compressed and displayed on the display screen.

  The problem to be solved is that the display cannot be selected locally or for the entire screen, and only video signal processing other than scaling is performed. In addition to the example shown in the built-in fixed display module, as an example, it is not possible to perform an immediate video calculation function of an immediate map image and video frequency processing. Therefore, how to find a video signal processing system and its method, allowing the user to select a local or full screen, perform video signal processing for all or local screens other than the built-in display module, and to meet the needs of the user The problem is to solve the problem in response to the needs of the user.

It is a main object of the present invention to perform a process on the display screen and display it on the display screen based on the user's request to meet the user's request.
