luminance encoding
A programmable gain is first applied to the luminance data output from Data Manager or Scaling Processor
depending on whether the Scaling Processor is bypassed or enabled. The luminance gain is defined by GAIN_Y
register at subaddresses 5F and 60. The horizontal sync, vertical sync and setup insertion are then performed.
Both black level and blank level are programmable through BLACK_LEVEL and BLANK_LEVEL registers at
subaddresses 5D and 5E, respectively.
All the transition edges of the luminance signal, such as sync edges and active video edges, are properly shaped
and filtered to limit the bandwidth within the standards.
luminance low-pass and interpolation filter
After all the necessary components of luminance signal have been added, the resultant signal is low–passed
and interpolated to 2X–pixel rate. This 2X interpolation simplifies the external analog reconstruction filter design
and improves the signal–to–noise ratio. Refer to Figures 8 and 9 for the filter frequency responses.
