Topfield USER GUIDE DIGITAL CABLE RECEIVER TF 100 C - Manual (Page 22)

16 Preference Settings
digital receiver linked to your television via this connector,
you should set the Video Output option to your desired colour
model. If you have connected via the RCA connector labeled
VIDEO on the back panel, you do not have to set this option
because the digital receiver outputs CVBS video through the
RCA connector independent of the SCART connector.
It is known in general that the RGB colour model provides the
best video quality with little difference from the YUV colour
model but the CVBS colour model does the least. So RGB
would be most desirable for this option.
3.2.3 Video cassette recorder
You can have the digital receiver linked to your video cassette
recorder or such an appliance via the VCR SCART connector. In
that case, the digital receiver will operate differently depending
on the setting of the VCR Scart Type option. If the option is
set to Standard, the digital receiver will pass the video from
the video cassette recorder to your television when it starts
playback. But if the option is set to External A/V, the digital
receiver will not pass the video automatically. To pass it, you
have to press the
button.
3.2.4 Television aspect ratio
If you have a wide-screen television, set the TV Aspect Ratio
option to 16:9.
Otherwise, if you have a normal-screen television, set the TV
Aspect Ratio option to 4:3.
