ADV7181C屬于集成電路（IC）的編碼器解碼器轉(zhuǎn)換器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADV7181C編碼器，解碼器，轉(zhuǎn)換器該系列產(chǎn)品可用于將信息封裝或編碼為適合于傳輸或存儲(chǔ)的格式，和/或在通信路徑的另一端執(zhí)行逆運(yùn)算，通常是通過(guò)使用某些形式的調(diào)制過(guò)程。示例包括從數(shù)字?jǐn)?shù)據(jù)生成模擬視頻信號(hào)的器件（反之亦然）；基于傳輸目的對(duì)按鈕的狀態(tài)進(jìn)行編碼的器件（實(shí)現(xiàn)遠(yuǎn)程控制功能）；以及便于將標(biāo)準(zhǔn) UART 連接到標(biāo)準(zhǔn)紅外收發(fā)器的器件。

GENERAL DESCRIPTION

The ADV7181C is a high quality, single-chip, multiformat video decoder and graphics digitizer. This multiformat decoder supports the conversion of PAL, NTSC, and SECAM standards in the form of composite or S-Video into a digital ITU-R BT.656 format. The ADV7181C also supports the decoding of a component RGB/YPrPb video signal into a digital YCrCb or RGB DDR pixel output stream. The support for component video includes standards such as 525i, 625i, 525p, 625p, 720p, 1080i, and many other HD and SMPTE standards. Graphics digitization is also supported by the ADV7181C; it is capable of digitizing RGB graphics signals from VGA to SXGA rates and converting

them into a digital DDR RGB or YCrCb pixel output stream. SCART and overlay functionality are enabled by the ability of the ADV7181C to process simultaneously CVBS and standard definition RGB signals. The mixing of these signals is controlled by the fast blank pin.
