Abstract

Circuit for realizing high resolution and clear TV set in 1080P / 60 format connected to decoding board includes following parts: high bandwidth and high speed switching chip connected to interface of YPBPR input end on the decoding board, sampling chip through series resistance and capacitance of cutting off DC coupled to the said switching chip, carrying out sampling operation and A / D conversion; digital process chip (DPC) connected to the sampling chip for transferring digital signal in 30BIT parallel data stream. DPC implements line and field general locking, line frequency normalization process, and D / A conversion, outputting R, G, B and HD, VD signals. High bandwidth and high speed switching chip is P15V330 type, sampling chip is MST9883 type or AD9883. The invention is applicable to high resolution and clear compatible TV set.

Description

technical field

[0001] The invention belongs to the technical field of television circuits, and more specifically relates to the design of television circuits realizing high-definition 1080P / 60 format. Background technique

[0002] 1080P / 60 is the highest format in the high-definition standard format stipulated in SMPTE. SMPTE is the abbreviation of the Society of Motion Picture and Television Engineers, which is the English name of the "Society of Motion Picture and Television Engineers". The SMPTE standard is very authoritative in the world's film, television and multimedia industries. It specifies many display formats from HDTV 1080P, 1080i, 720P to SDTV. 1080P / 60 signal has a large amount of image information per frame (twice that of 1080I / 60), and the image is real and delicate. With the development of technology, it will surely become the mainstream of high-definition format in the future. However, because its clock frequency is twice that ...
