1* Texas Instruments TVP514x video decoder
2
3The TVP5146/TVP5146m2/TVP5147/TVP5147m1 device is high quality, single-chip
4digital video decoder that digitizes and decodes all popular baseband analog
5video formats into digital video component. The tvp514x decoder supports analog-
6to-digital (A/D) conversion of component RGB and YPbPr signals as well as A/D
7conversion and decoding of NTSC, PAL and SECAM composite and S-video into
8component YCbCr.
