4.2.2.1 DAC setting with different TV Output Type on HH2
Currently there is a new video card named “Hominy Hill2” that uses the CX25899 as the TV encoder. There are four
analog outputs on that card, which can be configured to different signals in order to adapt to the different TV Output
Types. In video.reg, there are 4 parameters for analog output’s setting, “DACA, DACB, DACC, DACD”.
So if the parameter “TV Output” is set to 1 (Composite + S-Video), 2 (Composite) and 3 (S-Video), the DACs need
to be set to:
“DACA”=dword:4
“DACB”=dword:3
“DACC”=dword:2
“DACD”=dword:1
Else if the parameter “TV Output” is set to 4 (Component) and 6 (Composite+RGB), the DACs need to be set to:
“DACA”=dword:3
“DACB”=dword:1
“DACC”=dword:2
“DACD”=dword:4
Option 6 of “TV Output” is for a special TV connector named “SCART I” which is very popular in European. This
option is only available for the “Hominy Hill2” now since it can output four analog video signals at the same time.
The default DAC setting in video.reg is for “Lost Creek”(CX25892) when you select the "PortDrivers" as "cx873",
so please modify this setting if the video card is changed among “Miller Creek”, “Lost Creek” and “Hominy Hill2”.
