Decoder mode
Press F1 to switch the input between COMP for a composite input signal and Y/C for an
S-Video input signal.
Press F2 to switch through AUTO, 8 bit and 10 bit. AUTO allows the board to switch to
the appropriate bit mode based on the input signal timing stability. In PAL the Filter text
above F4, will be updated automatically as the board switches between bit modes.
When the board is set for PAL, composite input with 10 bit decoding, F4 can be used to
toggle between adaptive comb decoding or BNDSPLT for high quality bandsplit
decoding.
Simple decoding is automatically selected for 8 bit mode and comb is automatically
selected for 10 bit Y/C mode.
In NTSC, F4 is used to toggle SETUP ON or OFF.
Note:
10 bit mode is not available in NTSC when Y/C is selected. Use the DEC102S for 10 bit
mode with NTSC inputs in Y/C format.
Setting gain and black level
Press F2 from the home menu to display the top Level menu providing the following
functions:
Luminance gain and offset (black level)
Chrominance gain
The gain and black level adjustments are independent for 8 and 10 bit modes as well as
comb, bandsplit and Y/C modes. For example, if the unit is set up in 10 bit mode and
subsequently adjusted in 8 bit mode, the 10 bit adjustments are maintained and will be
restored when 10 bit operation is resumed.
There are effectively five sets of independent gain and offset adjustments; 8 bit
composite, 10 bit comb, 10 bit bandsplit, 8 bit Y/C and 10 bit Y/C.
