Operating modes
To provide optimum performance with a wide range of sources the DEC105S can operate
in a number of different modes.
Input modes
Description
10 bit comb PAL/NTSC
composite
Uses a line-based comb decoder, which mixes to simple decoder
when the comb would produce artefacts.
10 bit bandsplit PAL
composite
High quality analogue bandsplit mode provides best results when
PAL material is unsuitable for line-based comb.
10 bit Y/C (S-video)
Suitable for use with well-timed PAL sources.
8 bit composite
8 bit Y/C (S-video)
All 8 bit modes use a robust simple decoder. These highly tolerant
modes are particularly suitable for use with poorly timed sources
such as VHS recorders or satellite feeds.
Each operating mode has its own luminance and chrominance gain, offset and phase
settings and both 525 and 625 line standards have separate horizontal and vertical timing
settings. All these parameters are automatically maintained when power is cycled.
