[opendtv] DTV DVB

Stephen

Yes all that is required is to replace the exciter with a DVB unit.
The typical IF from a DVB unit is 36Mhz not 44mhz so the upconverter LO will 
have to be reset, and probably the PA pre-correction adjusted.

It's not a particular problem though and I did it numerous times when I had to 
swap between a Harris VSB exciter and a NDS DVB exciter during The Australian 
tests where we used the same transmitter for both standards.

There are many HD and SD settops in the Australian market that do 6 Mhz as Well 
as 7 Mhz.

Have a look at the following URL

This is a USB tuner (AVerTV DVB-T Volar) for DVB-T in 6,7,or 8Mhz That just 
plugs into a laptop and gives SD and HD facilities.
No ATSC though!

The PCMCIA version is similar with FM radio as well.

The specs on the hybrid+ volar are:
