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 DVD’s 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.

Not Enough Component Ports My Viewsonic N3000W LCD HD TV has two component ports; Y, PB, PR and Y, CB, CR. Both my Rogers PVR HD and Philips 642 DVD are equipped with Y, PB, PR connectors. I am currently using a switchbox to connect the two devices. The viewsonic also has a DVI and VGA port as well as three AV/S-Video ports. According to Viewsonic HDMI to DVI connectors won't work on their sets and I have tried this. Is there anyway to get a Y, PB, PR to work on Y, CB, CR connectors? I don't want to buy a receiver to manage my single Y, PB, PR port. Being a couch potato it's a hassle to manually switch these devices. Any ideas?

ExpressVu Multi-Receiver Installation
I am currently subscribed with Bell ExpressVu and have 5 standard def. receivers that I have hooked up to a 2x8 multiswitch. I would like to add a HD receiver to my set up but do not know what additional equipment I will have to buy. I would like to know if there is such a multiswitch that will allow HD and standard def. in a single 4x8 multiswitch that is compatible with Bell ExpressVu. Failing a single multiswitch to handle this request, can I currently use my 2x8 and add another piece of hardware to handle my single HD receiver? Thank you for your time!
Comment from Admin.
The first thing you will need is an HD satellite receiver, such as the 6000 or an HD receiver with PVR, such as the new 9200. These have both an SDTV/NTSC output and an HDTV output, Y, Pr, Pb and also HDMI in the case of the 9200. The SDTV/NTSC output could connect directly to your existing switch and the HD set could connect directly in HDMI or Y, Pr, Pb. An SDTV/NTSC output from the switch might also connect to the HD set. There do exist HDMI switches (2x1, 4x1, 4x4) but I see little need for it in your system when there is only one HD source and set. I am not aware of combination units.(See www.gefen.com or www.pacificcable.com for details of typical units).

Component Cable Hookup As you will note, I am a novice at this stuff. I have a projector that I use for my home theater. The projector has one set of component inputs. I am wanting to hook up my satellite receiver AND my DVD player with both using component cables. Is there some type of box that will accept two component inputs and have one component output that will go to the projector? I want something that will handle an HDTV signal.
Comment from Admin.
Suitable switches for HDTV analog components and for digital HDMI or DVI are available from a number of vendors in the Home Theater category. VPI (vpi.us) makes a simple mechanical unit that has two inputs and one output. Zektor (zektor.com) offer a 4 input, one output switch with IR remote control. Both use RCA Y, Pr, Pb and L/R audio connections. There a many others. Do a web search for HDTV component switches and you will see plenty more.

What is the point
I had 4:3 TV and when I used to watch movies on DVD I got 2 bars at the top and at the bottom. Now I have a 48" 16:9 TV and I still get those 2 bars so what’s the point of buying a 16:9 TV. I use a component cable and I even tried S VDO but same thing. I thought that after buying a 16:9 ratio TV I might get rid of those 2 bars but I thing I was wrong. Any suggestions, please.
Comment from Admin.
Apparently your DVD player does not know that it is connected to a 16:9 display and is continuing to make a 4:3 picture format. Look into the Setup menu of the DVD player and find where the display format is entered. Set it to 16:9. Then connect the DVD player to the component input of the HD 16:9 set using three cables Y, Pr, Pb. Look at the CDTV web site at http://www.cdtv.ca/en/what-is-hdtv/how-to-install.htm and check the manual for the DVD player.
This should resolve the problem.

In reply to "What is the point?", a 16:9 widescreen set is a much better way of watching a widescreen DVD than a standard 4:3 set. In order to get the maximum advantage you need to follow the advice given by ADMIN in response to your question. However this advice will not eliminate the letterboxing (black bars at the top and bottom of the screen) of the picture unless you are prepared to watch a clipped or distorted picture by making playing around with the wide mode options of your TV (not recommended). However, the picture will fill a larger percentage of the screen and the black bars will be narrower in all cases and almost unnoticeable in many cases.
Most widescreen DVD's titles have aspect ratios greater than the 1.78 (16/9) ratio of your 16:9 TV. Only programs made for HDTV (and the DVD versions of them) have an aspect ratio of exactly 16:9.
The most common aspect ratios for North American movies nowadays are 1.85:1 and 2.35:1 (Panavision). A DVD title with an aspect ratio of 1.85:1 will fill 96% of your screen and the black bars will be barely noticeable. One with a 2.35:1 ratio will fill 76 percent of the screen. By way of contrast, on a 4:3 screen these percentages will be only 72% and 52% respectively.
Your 48" screen has a width of 41.8" which is the same as the width of a 52.3" set with a 4:3 screen. You do not say how big your 4:3 set was but if I assume that it was 32" then the picture a widescreen DVD produces on your 48" widescreen set will be 2.67 times the size of that on the 32" set, as long as the aspect ratio of the DVD title is 1:78 or greater. That's a huge picture for home viewing, one that is large enough to justify always buying the widescreen version of a DVD when there is a choice between full screen and widescreen versions. Buying the widescreen version allows you to watch a movie in the form that the director wanted it to be seen.
I have saved the best for last as far as DVD viewing is concerned. The widescreen versions of many DVD titles today are anamorphic. These are usually labeled as "anamorphic" or "enhanced for 16:9 TV's". You may already own a few. These DVD's can be shown on either 4:3 TV's or 16:9 TV's. On a 4:3 TV an anamorphic DVD title offers no advantage over a non-anamorphic one of the same aspect ratio. However, on a 16:9 TV an anamorphic DVD will produce a noticeably sharper picture because the image sent to the inputs of your TV by the DVD player will contain 33.3% more horizontal scan lines in the actual picture area than that of a non-anamorphic title of the same aspect ratio. The image sent to your 16:9 TV also contains 33.3% more scan lines that the same DVD sends to a 4:3 TV.
So, set your DVD player up for 16:9 TV, don’t let the black bars bother you, and enjoy your widescreen DVD’s. You should find it a more enjoyable experience than watching the same DVD’s on a 4:3 set.

DVI/HDMI I have a JVC 30W585 HD TV which has a HDMI jack on the back of the set. MY 3250HD Rogers box uses DVI.
Are there adapters which will allow me to use either cable type?
Comment from Admin.
Yes adapter cables do exist and are available in the market. See http://www.monstercable.com/home_av/video_cables//HDTV_digital.asp
For one possibility. Monster Cables are sold in Canada by Futureshop.

SETUP
I just bought an LCD HD Ready TV and obtained the HD Digital Terminal from my cable company. I set it up like my old one, ie. (1) Cable into Digital Terminal (2) cable from Terminal into "old" stereo VCR (3) cable from VCR to TV.
Question: Am I losing anything by running from the Terminal thru my VCR ie. do I NEED to run right from the Terminal to my TV to get the best HD signal?
Comment from Admin
Running the video from the Cable Box through the VCR is not a good idea, as this results in only SD quality from ALL sources.
Best to connect up the HDTV signal directly to the HHD television. If the HD television has an HDMI (or DVI) input connect this to the HDMI output of the cable box (assuming your’s is so equipped) using the appropriate cable. If this does not work, connect the Y, Pr, Pb component outputs of the cable box to the similar inputs of the HD television using three RCA cables and connect the L and R audio outputs of the cable box to the associated L and R analog audio inputs of the HD television. Then you will have full HDTV with stereo sound. Retain the RF connection via the VCR for SD programming and for recording. For HD programs you will then select the HD input on the menu of the HD television.
For more information look in this site at Connecting HDTV.

HOOKUPS
i would like to know with a home theatre system do you hook the HDTV terminal to the TV or the hts.i had to unhook mine and now I’m having a hard time hooking everything back up
Comment from Admin.
The hookup of the HTS is shown in the Connecting HDTV section of this site in the sub-section Installing a Home Theater. Likely in your system, the HDMI or Y, Pr, Pb analog HDTV signal from the Set Top Box should go directly to the HD television input.

TV: Panasonic TH-42PD50
Satellite Receiver: Standard Digital signal, only s-video output.(Bell ExpressVu 3100)
Would I see a difference in image with normal channel if I bought a new Satellite Receiver with component video output connections but without purchasing HDTV channels.
What options would I have.
Thank you
Comment from Admin.
There would be only a minor improvement in image quality by going to an analog component connection, as the video compression for satellite transmission is really the dominant factor here. Hardly worth the effort and expense, unless you really want to move up to HDTV, which would effect a remarkable improvement in quality. That would certainly be my preference.

Wiring Questions for new home
I would like to have two High Dev (HDTV) sets in our house (Main floor) and downstairs wit 5.1 and either 6.1 or 7.1 downstairs. I would also like 4 or 5 other TV's in the house connected to Standard Def. but may want better some time down the road.
Does anyone know what types of splitters you need? I have a SW44 but that only does 4 HDTV and no others.
What type of video/audio distribution do you recommend if we wanted to wall mounnt a few of them. I have read about Audio Authorty and they are nice units 9870 I think but they are expensive and don't seem to do digital audio as well.
Thanks!

Component cables vs HDMI/DVI
I have heard that with component cables the maximum input/output is only 480p. To get true 720p/1080i you need to have HDMI or DVI cables is this true or false and where can I get information on this.
Comment from Admin.
The choice of interconnecting cable is unrelated to the format of the signal. Component analog cabling (Y, Pr, Pb) can carry any of the ATSC formats, as can HDMI or DVI. The difference is that DVI and HDMI interconnections are digital and thus the resulting picture quality in any format will be somewhat better than that of an analog component interconnection. HDMI also has the advantage that the audio is also carried in digital form. There is more information on this subject in this site in Connecting HDTV under Cables and Connections.
