The TVP7002 should default to the CSC coefficients required for HDTV component video inputs. The TVP7002 supports the ability to bypass the CSC block and defaults to the bypass mode (bit 4 of subaddress 18h). RGB-to-YCbCr CSC coefficients for HDTV component video (see CEA-770.3-C, ITU-R BT.709) (default coefficients): G' B' R' Y 00000016E3 000000024F 00000006CE Pb FFFFFFF3AB 0000001000 FFFFFFFC55 Pr FFFFFFF178 FFFFFFFE88 0000001000 RGB-to-YCbCr CSC coefficients for SDTV component video (see CEA-770.2-C, ITU-R BT.601) (informative only): G' B' R' Y 00000012C9 00000003A6 0000000991 Pb FFFFFFF566 0000001000 FFFFFFFA9A Pr FFFFFFF29A FFFFFFFD66 0000001000 4:4:4 to 4:2:2 Conversion For 4:4:4 YPbPr component video inputs, the TVP7002 can downsample the chroma samples (CbCr) from 1× to 0.5× using a 27-tap half-band filter. NOTE • Selection between the 30-bit 4:4:4 output format and the 20-bit 4:2:2 output format is made using bit 1 of register 15h. • Multiplexed CbCr data is output on BOUT [9:0] in the 20-bit 4:2:2 output format. • 4:4:4 to 4:2:2 conversion is implemented after RGB-to-YCbCr color space conversion. Sync Processing Horizontal Sync Selection The TVP7002 provides two HSYNC inputs and three analog SOG inputs for HDTV and PC graphics inputs. The sync input used by the horizontal PLL is automatically selected based on activity detection.
