APPLICATIONS DVD Playback Systems, PC Video/Multimedia Playback Systems GENERAL DESCRIPTION The ADV7190/ADV7191 is part of the new generation of video encoders from Analog Devices. The device builds on the perfor- mance of previous video encoders and provides new features such as Digital Noise Reduction, Gamma Correction, 4 ¥ Oversam- pling and 54 MHz operation, Average Brightness Detection, Chroma Delay, an additional Chroma Filter, and so on. The ADV7190/ADV7191 supports NTSC-M, NTSC-N (Japan), PAL N, PAL M, PAL-B/D/G/H/I, and PAL-60 standards. Input standards supported include ITU-R.BT656/601 4:2:2 YCrCb in 8- or 16-bit format. The ADV7190/ADV7191 can output Composite Video (CVBS), S-Video (Y/C), Component YUV 1, or RGB. The analog component output is also compatible with Betacam, MII and SMPTE/EBU N10 levels, SMPTE 170M NTSC, and ITU- R.BT 470 PAL. For more information about the ADV7190/ADV7191’s features, refer to Detailed Description. Continued on page 11 |
