RF problem

23-12-2004, 15:12

Hi,
Very new to the forum so apo logies if this has been discussed earlier.
Previously had RF connected to Video and then a boosted signal fed to 4 other TV's. STB went backside up so had a Samsung installed yesterday. When I select what was the video channel to watch cable progs have a very poor picture. Have tested cables and swapped boosters (which don't seem to be boosting) but still get awful picture. Ideas please?

Many thanks for a very warm welcome.

I have tried tuning the video but cannot alter poor picture. Do you mean that I should tune RF on the STB?

can you do a drawing of how your kit is connected

You could try changing the RF channel of the STB. Have a look at http://www.cableforum.co.uk/kb/81/ho...nel-on-the-stb

Thank you both for responding.

I haven't been able to figure out how to draw and attach drawing so I will try and explain.
NTL cable in to STB;STB SCART connection to 3 way SCART splitter and Video which has SCART to 3way SCART switcher. DVD connected to SCART switcher. SCART switcher connected to TV.
RF from STB to video, RF out is split to TV and via signal booster to wall socket and hence to 4 TV's.

Hope that this makes sense.

Since my Pace box went to STB heaven I have had a Samsung box. I have what sounds like a similar wiring set up (toi Vernon) to get the RF signal round the house. BBC1 and 2 and the STB selection have all now disappeared into a snow storm where as they were watchable before.

It seems to me that the signal level (SNR?) from the Samsung is not as good as the Pace box. Can that be altered or do I just need to put in a big RF amplifier as near as possible to the output of the STB?

You probably want something like this:

Have you tried re-tuning the televisions? There's a good chance that the Samsung is set up to transmit on a different channel than the Pace.

why do you need the RF from the STB to the Video? Surely using the scart is better?

1) So that the video can record a terrestrial channel at the same time as you are watching a cable channel on the main TV.

2) So the RF outputs of both the STB and the VCR are available to the remote televisions.

.. and also so that I can change channels on the TV in the bedroom without having to get out of bed, walk downstairs change the channel on the STB

except I can't see anything at the moment on the bedroom TV !!!!!

Since you have a Samsung box then you can use any old videosender to send back the remote control signals.

If you had an older Pace model then you'd need a DigiEye DG100DE:

Ah! You should make note of the fact that the Samsung STB does not have an analogue pass-thru (which an older Pace may have had) and as such, you will either need an aerial or to split the NTL cable (see diagram above).

huh? you need an aerial to be able to do this. Connecting the aerial to the STB and then to the video serves no purpose. It might as well go from the aerial to the video.

So how, then, is the signal from the STB going to get to the remote TVs - thought transference?
