Dvi Vs Component

Sole_Survivor

I found out the lowdown.


I found out that the hdmi to DVI or DVI allows other information to be sent along with the signal such as DIGITAL content protection, this will disable the picture (no picture) and use of a DVR to record when using a HD Tivo.

If you are not using a DVR the DVI will give you the 1080i signal even if the broadcast has the copyright protection, but you can't record in 1080i with future or current HD compatible recording products.

If you have a component connection and the broadcast HAS the copyright protection in it, the component connection will display the copyrighted HD broadcast in 480.

That is the main difference. Extra or compressed digital information lacking in component. If you have the HD DVR always go component, at least you can watch and or record the copyrighted HD broadcast in 480.

Of course there is a difference is picture because they are different connections.

I had on the same channel HD NET on the same TV using video 5 component and video 7 DVI.

The DVI gives a slightly tighter picture. What do I mean by tighter? Imagine getting clear plastic wrap and stretching from 4 angles N/S/E/W it until you see the wrinkles diminish and it becomes clear.

This is what most HD component connections look like but with the DVI it always seems to be the tightest.

If you like that sports illustrated glossy look and give up minimal tightness than component is the way to go. It also has better color & luminance in my opinion and it no surprise because component has one separate line for color and one for luminance.

1.Digital 2.luminace 3.color

When watching SD digital the component is better than DVI, this you can see this clearly in the commercials for some reason more than the show itself.

If you like the tightest picture look and wish to give some luminance and color than DVI is the way to go.

They are really both very good and both carry the 1080i signal. It matters what you like better.

After having a DVI monster cable connection for a year I decided to go component.

I decided not to buy the DVI-HDMI cable between my Comcast HD receiver and HDTV.

There sound no real benefit in getting the cable.

I found the quality of the component cable very pleasing to my eye. My audio out is via optic to my receiver. I will care less about the added benefit of audio via the HDMI cable.

Thanks again for the tip.

If you use a STB or STB/DVR with an HDCP output (DVI or HDMI) you will be able to record all broadcasts even those with a Broadcast flag if you use a DVI or HDMI connection the your HDTV. No exceptions.

Same answer as above...if you use a STB or STB/DVR with HDCP output to an HDCP TV input, you will still get HD and be able to record when a Broadcast flag is present.

Yes, provided the Broadcaster has filed a 30 day advice in advance to the FCC of his intention to downrez Component connection in the presence of the flag.

The reason is the HDCP Content Protection protocol. If you have a STB or STB/DVR with an HDCP output (DVI or HDMI) and your TV has a DVI or HDMI input, use it... it's a must. If your HDVTV does not have an HDCP connection, use a STB without an HDCP output and you will get HD even with the flag. All HD DVR's have an HDCP compliant connection.

Not necessarily. In most instances, a CRT RPTV will not have an improved PQ. However, a digital display TV gets a better picture with the uncompressed digital signal offered by DVI or HDMI.

I noticed a DRAMATIC difference when I replaced my component cable with an HDMI cable. Granted, it was the run of the mill component cable that Cox provided with the cable box.

I have a question about the DVI connection.
I already have everything connected to an audio receiver and a DTV STB. I'm using the optical for audio and everything else is RCA cables. DVD Recorder/VCR combo unit also hooked up to all the above.

My question, if I use a DVI connection from my STB into the TV, will I need to disconnect any of the other stuff that's already working. I think that using the DVI will improve my picture from what I've read.

TV is a Samsung 6163W and the DTV receiver is a Samsung TS360. The picture needs brightening up some (changing that in the TV setup only makes the picture look washed out even if the contrast is changed)
