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