The ADV7181B integrated video decoder automatically detects and converts a standard analog baseband television signal compatible with worldwide standards NTSC, PAL, and SECAM into 4:2:2 component video data-compatible with 16-/8-bit CCIR601/CCIR656.
The advanced and highly flexible digital output interface enables performance video decoding and conversion in line locked clock-based systems. This makes the device ideally suited for a broad range of applications with diverse analog video characteristics, including tape based sources, broadcast sources, security/surveillance cameras, and professional systems.
