The KS0127B converts analog NTSC, PAL or SECAM video in composite, S-video, or component format to digitized component video. Output data can be selected for CCIR 601 or square pixel sample rates in either YCbCr or RGB formats. The digital video can be scaled down in both the horizontal and vertical directions. The KS0127B also decodes Intercast, Teletext, Closed Caption, and WSS data with a built-in bit data slicer. Digitized CVBS data can
be output directly during VBI for external processing.

• Accepts NTSC-M/N/4.43, PAL-M/N/B/G/H/I/D/K/L and SECAM formats with auto detection
• 6 analog inputs: 3 S-video, 6 composite, or 1 3-wire YCbCr component video
