A method and system for processing 3D video signals of a modular TV

Abstract

The invention provides a method and a system for processing a module TV video signal. The method comprises the steps that: a final 3D video output format of a TCON board of a screen end and all 3D video formats supported by the screen end are obtained through a card end, and a final video output format of the card end is matched according to the obtained final 3D video output format and all 3D video formats supported by the screen end; the card end receives an input first 3D video signal, converts the format of the first 3D video signal into the final format, and transmits a second 3D video signal to the screen end after obtaining the converted second 3D video signal; and the screen end receives the second 3D video signal, carries out driving display on the second 3D video signal to enable the card end to convert the received video signal according to the video output format supported by the screen end, after receiving the video signal in the acceptable format, the screen end can smoothly display the 3D video input signal, and then normal display of 3D videos by a module TV is realized.

Description

technical field [0001] The invention relates to the technical field of modular TV signal processing, in particular to a method and system for processing 3D video signals of a modular TV. Background technique [0002] The modular TV is different from the traditional TV. It divides the main board of the traditional all-in-one machine into two parts: the card end (smart card) and the screen end (screen end board). The main board of the traditional all-in-one machine processes the 3D signal from the signal source. At the beginning, the input video is separated into left and right data frames, and then the external glasses are controlled to synchronize the delay, etc., all of which are completed under the unified control of the motherboard SOC (SOC is the abbreviation of System onChip, called a system-on-chip). For modular TVs, the card side of the smart card is mainly for signal processing, while the function of the screen side is concentrated on display. Therefore, the processi...
