Embodiment Construction
[0059] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0060] The invention converts the analog image signal of the TV set into a digital image signal, and then debugs various line scanning distortions of the digital image signal through the remote control to control the encoding output phase of the digital image signal, and finally converts it into an analog image signal output. Various operations in this process do not need to be directly performed on the line scanning circuit of the TV set, but are performed on various scanning distortions through an external remote controller, which is convenient, quick and low in cost.

The present invention relates to a television, which provides a system and a method for correcting the scanning distortion of the television. The method includes the following steps: A, an analog image signal received from the television is converted into the digital image signals and stored; B, the stored digital image signals is digital-processed, and the digital-process includes encoding the digital image signals; C, the distortion correction data is modified according to the remote control signals transmitted by a remote-controller, and the encoding output phase of the digital image signals is controlled by using the modified distortion correction data; D, the phase-shifted digital image signals are converted into the analog image signals, and output to display. The present invention improves the production efficiency of the television and reduces the production and maintenance cost by digital-processing the analog image signals of the television in debugging process of televisionproduction, and using the remote controller to debug various scanning distortions.
Description
technical field [0001] The invention relates to a TV set, and more specifically, to a system and method for debugging the scanning distortion of the TV set. Background technique [0002] At present, cathode ray tube (Cathode Ray Tube, CRT) televisions are gradually developing towards ultra-thin, large-screen, digital, and high-definition aspects, and people's requirements for scanning distortion indicators of CRT televisions are also constantly increasing. [0003] CRT television scanning distortion mainly includes geometric distortion, S-shaped distortion, pincushion distortion and saturation scanning distortion. Among them, the geometric distortion is mainly caused by the inconsistent technical parameters of the deflection yoke caused by the poor production process of the deflection yoke; the S-shaped distortion is caused by the inconsistency between the angular scanning rate and the line scanning rate during the electron beam deflection scanning of the CRT picture tube; t...
