Overview
The ADV7281WBCPZ-RL, produced by Analog Devices Inc., is a versatile one-chip, multiformat video decoder. This device automatically detects standard analog baseband video signals compatible with worldwide NTSC, PAL, and SECAM standards in the form of composite, S-Video, and component video. It converts these analog video signals into a YCrCb 4:2:2 video data stream, which is compatible with the 8-bit ITU-R BT.656 interface standard. The ADV7281WBCPZ-RL is part of the ADV7281 family, which includes variants with different numbers of analog input channels and output interfaces.
