The DPTV-3D673 is a image processing IC which is used in the super-large screed rear projection color TV sets, such as the Changhong HP series Precision Vision King and so on. 1.Its functional features. The DPTV-3D6730 IC's internal circuit can be used to complete the image signal's A/D (analog/digital) conversion, NTSC/SECAM modulation and decoding, scanning frequency and format conversion, 14D dynamic picture quality enhancement, digital/analog (D/A) conversion and so on. (1)Its decoding circuit. The decoding circuit has a 3D comb filter controlled by the program, which can support PAL/NTSC/SECAM formats and isolate the Y/C signals. The color edge enhancement circuit can improve the color transient characteristics. (2)Screen diaplay modes. The screen display modes mainly have: picture-out-picture display mode, picture-in-picture display mode, panorama display mode. It supports 16:9 and 4:3 screen ratio and other modes.
