The device builds on the performance of previous video encoders and provides new features like inter- facing progressive scan devices, digital noise reduction, gamma correction, 4 × oversampling and 54 MHz operation, average brightness detection, black burst signal generation, chroma delay, an additional Chroma Filter, etc. The ADV7194 supports NTSC-M, NTSC-N (Japan), PAL N, PAL-B/D/G/H/I and PAL-60 standards. Input standards sup- ported include ITU-R.BT656 4:2:2 YCrCb in 8-, 10-, 16- or 20-bit format and 3 × 10-bit YCrCb progressive scan format. The ADV7194 can output composite video (CVBS), S-Video (Y/C), Component YUV or RGB and analog progressive scan in YPrPb format. 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 ADV7194’s features refer to Detailed Description of Features section.
