SDA 9280 B22
Subaddress 06_H: Compander Control
Bit
Name Function
D0
COMEX Compander working condition:
0:
signal compression
1:
signal expansion
Note: For oversampling without compression or expansion
COMEX = 0 is recommended in order to minimize the signal
delay time.
D1
COMP Compander activation:
0:
bypass
1:
compander active
D7 ... D2 READD
Compander, displayed picture part: (shifting raster: 4 pixels)
000000: not recommended
000001: left part of the picture
:
:
111111: right part of the picture
Note: For signal compression READD = 101101 is required. For
oversampling without compression or expansion
READD = 000001 is required.
Subaddress 07_H: Oversampling Control (Interpolator 2) and Background Activation
Bit
Name Function
D0
OVSAMP Oversampling control:
0:
doubling of sample frequency OFF
1:
doubling of sample frequency ON
D1
OVFILT Oversampling control (OVSAMP = 1):
0:
interpolation filtering OFF
1:
interpolation filtering ON
D2
BACKGR Activation of background insertion:
0:
insertion OFF
1:
insertion ON
D7 ... D3
No function assigned. Assign binary value: 00000
