Method and system for processing image of modular television

Abstract

The invention discloses a method and a system for processing an image of a modular television. The method comprises the steps as follows: when the modular television detects an external input signal, a smart card end pretreatment is carried out on the external signal through a smart card; an HDMI signal output by the card end is obtained and transmitted to a screen end plate; the screen end plate receives the HDMI signal output by the card end and carries out a screen end pretreatment on the HDMI signal output by the card end according to screen end adjustment parameters which are set by the screen end plate in advance; and a screen end output signal is obtained and displayed. The smart card and the screen end plate in the modular television are clearly separated from a functional module for video processing, so that the video processing effect is optimized; meanwhile, the data processing workloads of the smart card and the screen end plate are reduced; the processing efficiency is improved; and the standard HDMI signal is output after the external input signal is processed by the smart card, so that the effect of the video output by the screen end plate is kept consistent after the smart card is replaced and the standard HDMI signal output by the smart card is received by the screen end plate.

Description

technical field [0001] The present invention relates to the technical field of television, in particular to a modular television image processing method and system. Background technique [0002] The main board of traditional all-in-one TV is converted from the input signal format to the final display driver, all of which are processed by SOC (System on Chip, that is, system on chip), which brings a huge workload to the SOC in the all-in-one TV. [0003] At the same time, the whole process of video from input to display output will go through multiple processing processes, such as noise reduction, deinterlace (that is, control the frame rate of the video), scaling (that is, control the zoom of the video), brightness adjustment, chromaticity adjustment, etc. process. The above processing flow can be processed on the smart card or on the screen end board. [0004] The smart card is upgradeable and replaceable, so in order to ensure that the signal output from the replaced sma...

Problems solved by technology

[0006] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a modular television image processing method and system, aiming at solving the problem that all the data processing of the all-in-one TV in the prior art is handled by the SOC instead of the smart card and the screen terminal. The board has a clear division of labor, and at the same time, the processing flow of the smart card for the input signal is still not unified, and the signal output to the screen terminal board is not a standard HDMI signal, resulting in the defect that the smart card cannot be replaced at will
