DEC103S
As DEC102S with the addition of 'bandsplit' decoder
option. This is an additional 10 bit decoding system
for PAL composite inputs. With some types of real pictures
this produces improvements in picture sharpness, and
reduction of comb artefacts. The DEC103S is recommended
for broadcast use in PAL systems. The DEC103S loses
the 10 bit Y/C input in NTSC use, and so the DEC102S
is recommended in NTSC systems. When both standards
are used, the DEC103S can be used for improved PAL decoding
at the expense of NTSC Y/C input, or the DEC102S can
be used if 10 bit NTSC Y/C input is required
DEC101S
This is a reduced cost DEC103S, with only the 8 bit
decoder. It converts both composite or Y/C input, but
uses the 8 bit decoder for stable as well as unstable
sources. This is an ideal decoder to use with VHS or
other non-broadcast composite or Y/C sources. All inputs,
features and operation modes are the same as DEC102S
but with reduced analogue performance. Power consumption:
6.25 watts
