Enhancement

To control aliasing in down conversion and to add a subjective impression of sharpness in upconversion

Vertical enhancement:

The V Enhance function enables controlled attenuation and gain to be applied to the chosen vertical frequency bands

Frequency band selection (Low, Med, High) with 5 preset enhancement levels (Soft 2,Soft 1, Normal, Sharp 1, Sharp 2)

Horizontal enhancement:

The H Enhance function enables controlled gain to be applied to the chosen horizontal frequency bands

Frequency band selection (Med, High), with 5 preset enhancement levels 0-4

Horizontal filter:

H filter frequency determines the frequency band in which the H filter shape function is applied

  • 5 preset levels (Low 2, Low 1, Normal, High 1, High 2)

H filter Shape determines the sharpness of the output by changing the rate of anti-alias filter cut-off in horizontal frequencies

  • 5 preset levels (Soft 2, Soft 1, Normal, Sharp 1, Sharp 2)

Noise reduction: Spatial, Recursive Y/C alignment: Corrects for up-stream luma chroma displacement

  • Input lock (SDI) – 3 fields + 1 ms

With scaling active in 525/59i output:*

  • Ref lock/Free run – between 2 and 4 fields + ~200 µs
  • Input lock (SDI) – 2 fields + 1 ms

With same standard in & out and Sync mode = Enabled:

  • Ref lock/Free run – between ~200 µs and 1 frame + ~200 µs
  • Input lock (SDI) – ~1 ms
