How to make a DVI or HDMI connection via optical cable? That is, what is the type of optical cable to use and what are the necessary hardware involved? For say, about 20 metres long.

Comment from CDTV Admin.

Details of the HDMI interface and cabling can be found at www.hdmi.org. Cables for HDMI, DVI and adapters between them are made by a number of companies, including Monster Cable, in the 20 m length needed.

HDCP Protection

Currently I own a 800x600 video projector that I would like to use to display 720p/1080i hdtv signals 'scaled down' to the resolution of the projector. To do that I have found a video processor/scaler that will accept an hdtv signal from the dish STB via a DVI input, and output a 800x600 scaled VGA signal to be fed to the projector - AS LONG AS THE HDCP IS 'TURNED OFF'.

Can you tell me if all Expressvu hdtv signals are HDCP protected, none are protected or if protection is only applied in certain instances (please specify).
Thanks.

HDCP Protection is a part of the DVI or HDMI output interface in the STB, be it satellite, cable or OTA. If your scalar can recognize and process HDCP it could work.

S-Video vs Component I just bought a 32 inch HDTV-ready LCD panel by Sharp. Upon getting home I realized that my Home Theater-In-A-Box (Pioneer, 5 years old) and noticed that there are no component connections, the best is S-Video. Will there be a big difference in the picture quality between S-Video and Component?

Comment from Admin.

The S-Video connection is for NTSC standard definition video and offers a small improvement over composite NTSC connections. The component connection to your monitor is for HD signals, as well as SD signals in component form. You will certainly see a marked difference on DVDís and there is no way for an S-Video connection to handle HDTV. Time to trade up on your Home Theater package!

Gold-plated cables

I have been told by my local retailer that the gold-plated (and much more expensive) cables (coaxial / RGB ' etc.) deliver superior digital signals. Is this true ?

Comment from Admin.

Gold plating on the connectors serves to improve the contact and to reduce oxidation and possible corrosion, making for greater long-term reliability, especially if the mating connectors on the chassis are also gold plated. The quality of transmission is set by the performance of the cables. Larger cables (not counting the outer plastic jacket) have a lower loss, all things being equal. For short lengths, the difference is minor, but for longer lengths (more than 2 meters) a good cable will give a better margin.
