Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] The general signal processing platform applied to the micro-display rear projection TV of the present invention, such as figure 1 As shown, the signal processing circuit is mainly divided into two parts: one is the analog signal processing part, and the other is the digital signal processing part. The analog signal part mainly includes high and intermediate frequency processing of the main sub-picture, video and audio processing of the main and sub-picture, and switch selection of various AV input signals. The digital signal processing part includes the digital decoding of the main sub-channel, deinterlacing unit (Deinterlace), expansion unit (Scaler), component input, RGB input, DVI input, display output and other parts. Of course, the technical solution of the present invention does not necessarily have to set the main...

Abstract

The general signal process platform for micro-display projection TV comprises: analog signal process part composed of picture process for high and medium frequency, video and audio process, and switch selection for all ways AV input signal; and digital signal process part composed of digital decode eliminate intersection unit and extension unit; at least a main high-frequency head to receive outer radio frequency signal, an AV diverter switch connected to the said high-frequency head and all ways signal, and at least a digital decode unit and an opposite voice power amplifier circuit; wherein, the decode unit connects to AV diverter switch and extension unit. This invention uses opposite chips in core members and improves the rate of performance and price.

Description

technical field [0001] The invention relates to a circuit device of a television, in particular to an improvement of a circuit applied to a general signal processing platform of a micro-display rear projection television. Background technique [0002] Now micro-display rear projection TV is more and more popular among consumers, and its inherent advantages determine the development direction of rear projection TV. But its signal processing system is the key of the whole machine. The general signal processing platform adopted by the existing micro-display rear projection TV has adopted a large number of IC chips in order to realize more diverse and gorgeous functions. brought about high costs. Now the price of micro-display rear projection TVs is obviously high, which is beyond the range that ordinary families can afford. [0003] Therefore, there are still defects in the prior art and need to be improved and developed. Contents of the invention [0004] The purpose of t...
