SCART to S-VHS adaptors.

Are SCART to S-VHS adaptors any good?

I ask because I was looking at a Video Projector today, and the only connections provided were D-SUB (ie. PC-VGA) and S-VHS.

Connecting my DVD Home Cinema isn't a probem because it is fitted with an S-VHS connector.

However, my Freeview box only has a SCART socket, so connecting it to the projector would require a SCART to S-VHS adaptor.

Also, can you get a switching box that would allow me to switch between my DVD and my Freeview box, when both are connected by S-VHS to the projector?

    This is a SCART breakout box, which means it doesn't convert RGB or composite video into s-video, but merely brings out the signals onto standard connections on the top of the unit. In other words, if you want to to use the s-video socket then your Freeview box must be capable of putting s-video out on its SCART socket. Check in your manual or in the on-screen settings.

    It's called a breakout box because it contains a SCART socket at one end and a plug at the other, which means your SCART connection goes straight through and the composite, audio and s-video signals are provided as breakouts. If you don't need a SCART passthrough, you can get similar adaptors which just have a SCART plug at one end and phono/s-video sockets on the other.

    If your Freeview box can't output s-video, then you can indeed get composite/RGB to s-video converters but they're not exactly cheap.

    e.g. http://www.keene.co.uk/electronics/multi.php?mycode=RGB2S (I'm sure there are others though)

    This one might work for converting SCART into VGA, but you'd have to look into it a bit more as I think the projector has to be able to handle TV-style sync as well as PC-style sync: http://www.keene.co.uk/electronics/multi.php?mycode=SBBVGA

    BTW the little round video connector with several pins in it is called s-video, not S-VHS. S-VHS is a type of video cassetter recorder. Although many people, including professionals, confuse the two!

    You need an s-video switchbox!

    Here are a couple:

    but I'm sure there must be cheaper ones, in particular dedicted 2-way s-video switches?

    I used the terminology they used HERE.

    If I'm spending £350 on the projector, and maybe another £100+ on a 120" diagional screen (proper Home Cinema ;) ), I'm not bothered about spending 50 quid on a switching box.

    BTW. I was thinking of this projector.

    Any thoughts?

    Since that is an Optoma projector, have a look at this! http://www.keene.co.uk/electronics/multi.php?mycode=APTAKIT

    This seems to suggest that the VGA socket on the projector can accept component input, although http://www.wedgwood-group.com/optoma_ep706_multimedia_projector.htm says that it accepts 800x600 SVGA PC signals. Perhaps it can accept both?

    Also see http://www.syncblaster.com/ to see if this gives any help.

    http://www.syncblaster.com/syncblaster_cables_faq.htm suggests, as I indicated before, that these particular SCART to VGA converters only work if the projector can accept TV-style horizontal sync of 15.625KHz - it it can accept component video (and indeed s-video and composite) then surely it must do.

    I don't know enough about this projector, and projectors in general, to advise on what will work with its VGA socket, but s-video will definitely work provided you can get s-video out of the Freeview box or buy a converter. The best quality signal however will be via the VGA socket.

    Are you suggesting I could do without the switchbox, by using S-VIDEO for the DVD player, and D-SUB for the Freeview box?

    If so, how would I get the sound from my Freeview Box into my DVD Home Cinema unit?

    It was more directed at getting the best quality via the VGA socket rather than getting rid of the switchbox, but yes that would be a result.

    You'd have to look at what connections you've got on the Freeview box and work it out. For example:

    1. Via explicit audio out sockets on the Freeview box.
    2. Via a SCART breakout adaptor, if the VGA converter does not cater for audio.
    3. Via the VGA converter, if it caters for audio.

    Sorry for taking up so much of your time.

    I must seem pretty thick. :o

    The Freeview Box has nothing but a SCART socket. It doesn't even have an RF out.

    Using the SCART to S-VIDEO, I figured I could connect the Freeview to the projector using the S-VIDEO and feed the audio through the DVD Home Cinema using the RCA connection.

    Or am I missing something obvious?

    PS. I don't think option 3 "Via the VGA converter, if it caters for audio" would work, because the projector doesn't, as far as I know, take audio and, in any case, I'd like the sound to go through my 5.1 speakers.

    Check that the Freeview box can output s-video on SCART. If it doesn't your only options are composite video if the projector will take it, or a SCART to s-video converter.

    VGA doesn't carry audio anyway - a SCART to VGA converter would put video onto the VGA socket and, if it caters for audio, it would put the audio onto separate phono sockets so you could take that to your surround system.

    Thanks.

    Boy is it complicated. :eek:

    If you feel up to it, do you know anything about Video Projectors and Aspect Ratios?

    No, sorry! I'm quite good with aspect ratios and how Sky boxes and TVs deal with them but I have no experience of projectors.
