This isn't really Home Networking as such (please move it to Scuttlebutt if appropriate!), but relates to my ignorance of how to network (!) a newly-obtained Freeview digital set-top box (UK only!), an ancient video recorder, and a senile TV.
See the nice picture below, about which I have a number of questions:
1) is there any reason why the aerial/RF connection (starting at 4) should need to be connected in the order shown: set-top box -> video recorder -> TV? Would any order whatever be allowable, so long as there was an aerial/RF connection to each box?
2) are all the aerial/RF cables/connections actually needed or do the scart connectors provide any pass-through for the aerial/RF signal?
3) is it possible for one or both of the set-top box and the video recorder to be switched off and still be able to get a signal on the TV via the aerial/RF connection? (That is, is there a 'passive' connectivity function)
4) am I right in presuming that the scart cables require that both boxes that they interconnect should be powered on to work successfully? (That is, they have no 'passive' connectivity function)
5) is the fact that my set-top box can find only about 14 (out of the about double that number available) Freeview channels likely to be because I have a manky old TV aerial designed years ago for analogue TV (which is all there was at the time)? (However, the aerial signal test Teletext page 284 only shows a problem on Channel 4 - BBC1/BBC2/ITV1 are OK)
Currently I have cheated by just taking the setup I had before obtaining the Freeview set-top box, and splitting the RF signal into two to connect also to the set-top box, then from there connecting to a spare scart socket on the TV. It means that I am familiar with the previous way of recording the ordinary 'terrestrial' channels, and can turn on Sky News (or whatever) via the set-top box. (Fortunately I can't ever see a need to record any of the Freeview channels currently available to me).
When the 'digital TV switchover from analogue' hits my region of the UK (2010-2011) I will want to get a new digital TV, a hard-disk Personal Video Recorder (PVR) and a replacement TV aerial on the chimney, but this may well keep me going until then...
