Embodiment Construction

[0047] The present invention is described in detail below in conjunction with accompanying drawing:

[0048] Such as figure 1 As shown, in the outermost frame is a video image digital processing chip circuit, the video image digital processing chip of this embodiment includes an ADC unit, a Video Processing unit and a DAC unit that are electrically connected in sequence, and the video image digital processing chip has a suitable Due to the structure of DIP packaging, DIP packaging is usually the packaging form used by CRT TV manufacturers to produce integrated circuits on the production line, and most of the existing video image digital processing chips use the QFP packaging form. Therefore, the video image digital processing chip Structural design is carried out to make its structure consistent with DIP packaging, then DIP packaging can be realized, so that the existing CRT TV can perform the same image processing function as digital TV, and realize the same high definition ...

Abstract

The present invention relates to the technology for using video image digital processing chip in CRT analogue TV. To solve the problem of high cost caused by change current production line when CRT analogue TV manufacturers use video image digital processing chip, the invention provides a video image digital processing chip suitable to be packaged in DIP mode and an ingegrated circuit (IC) using the same. The video image digital processing chip includes a video processing unit, a ADC unit and a DAC unit. The structure of the digital processing chip is suitable to be packaged in DIP mode. The application of the technology makes it possible to produce CRT analogue TV eqipped with video image digital processing chip withou t high-cost change of current CRT analogue TV production line.

Description

technical field [0001] The invention relates to a video image processing technology of an analog TV, in particular to a technology of a video image digital processing chip used in a CRT analog TV. Background technique [0002] High-definition digital television (HDTV), as the highest level of digital television, was first proposed by the United States. After eight years of technological development, the Federal Council (FCC) of the United States finally formally determined the specifications of HDTV terrestrial broadcasting methods and products in 1995. In 1998, the United States officially launched digital high-definition programs. Although the United States plans to completely eliminate analog TV and replace it with digital high-definition TV by 2006, in recent years, companies with strong technical development capabilities have begun to develop video processing Digital technology is used in the circuit to process signals, which improves the performance of analog circuits,...
