Cable box doesn't have an HDMI port.

I have basic Comcast's cable box - it doesn't have a html port to plug into my HD flat screen just a Component YPbPr.

Can I get a YPbPr to HDMI converter to work from the cable box to the TV?

What I've been reading sounds that it'll work, plus saying it will also "upscale" everything to 1080 and HD - how true it that?

If you receive HD through your cable box I doubt you would see any picture quality difference by converting to HDMI. Besides, with component connections you do not have to worry about the HDMI handshake issue that plague some other users.

Except if certain HDCP takes effect and analog video outputs become disabled. This can be found when connecting a copyprotected dvd to a vcr, the video flickering or dimming.

WTF are you talking about Mr Komkast????? Connecting a DVD player to a VHS player??? Video flickering and dimming????? You proudly post the Komkast logo but seem clueless when it comes to handshake issues associated with HDMI. As to date - no analog outputs have been disabled and component cables work just as well, and better in some situations than HDMI cables do. Folks, the man uses a komkast logo,,,,,,,,,,,there's yer tech support. :lol::lol::lol::lol::lol::lol:

I'm pointing out an example about copyright protection, and it not passing through the hdcp handshake over an analog connection. Not saying that itís currently like this, but the possibility later on down the road of this occurring. Some cable providers have copy protection enabled on all of their channels, while others only have it enabled on the premium channels.
I applogize that I assumed you were competent enough to understand this.

My first question is do you have a Comcast HD cable box ? or is the old standard cable box ? You did not indicate the cable box model number.

When pointing out handshake issues concerning copyright protection, your example of connecting a dvd player to a vhs player is so far out in left field that your own incompetency reflects your komkast logo. Please explain your version of handshake issues between dvd and vhs???

The Component will be fine for the 1080i or 720p signals Comcast sends. 1080P requires HDMI, DVI or VGA, but Comcast does not deliver 1080p signals.
You can also ask Comcast to bring out a box with HDMI

call your provider and DEMAND a set top box that offers HDMI..this is your solution..40 " flat panel and smaller - not a noticable difference between component and hdmi,,40 " and larger flat panel..get a new box...also if you do change,,dont freak out when your tv adjusts from 1080 to 720 and 480 ,,there will be some delay on the picture while the cable box and the hdmi cable adjust signal according to what the tv station is kicking out...for instance( where i live espn hd kicks out in 720, and hd theater kicks out 1080 ,,,so when changing between these two channels you will see adjustments on the screen,, i hope this was helpful to

OMG - another genius.
Doesn't matter what the size of the display, there is NO difference between PQ whether one uses HDMI or component.
Additionally, the cable box "kicks out" what ever you tell it to in the set up menu.

To the OP, just use component cables from the box to the TV.
Whether your box will upscale to 1080 . . . depends on the box - have you checked the manual?

After I stopped laughing I decided to add I totally agree with you. I loved your opening: OMG another genius.

Unless I'm 101% sure of my answer I will not respond to a person's problem.

Keep up the good info and humor. :yippee::haha:

Yea, HDMI or Comp cables make no difference with Comcast. They currently do not display 1080p video to Comp cables are fine. If you want to use just a single cable for video and audio to your TV, then HDMI might be nice and I think the ywill bring out an HDMI box if you ask, or drop by a COmcast store if there is one close by.

HDMI or Component cables make no difference . . . PERIOD!!!!

They currently do not display 1080p video to Comp cables are fine.
And if they did provide 1080p output, component cables would be capable of delivering the signal and perfectly suitable.

Just a bit overstated. :)

I have a Motorola DCT 3412 connected to a 50" Panasonic plasma (768p) and the HDMI output looks considerably better than component. Here's what bluejeans cables has to say on the issue:

The Upshot: It Depends
So, which is better, HDMI or component? The answer--unsatisfying, perhaps, but true--is that it depends. It depends upon your source and display devices, and there's no good way, in principle, to say in advance whether the digital or the analog connection will render a better picture. You may even find, say, that your DVD player looks better through its HDMI output, while your satellite or cable box looks better through its component output, on the same display. In this case, there's no real substitute for simply plugging it in and giving it a try both ways.

Which of course makes it pretty clear that any differences resulting in a "better" picture are NOT due to the cable, but to the signal processing in the equipment.
In your case, it is quite likely that you have NOT calibrated BOTH the HDMI and the component inputs on your TV;
most who do have reported that after calibration they do not see any difference.

The fact remains: HDMI or Component cables make no difference . . . PERIOD!!!!

Not correct.

The fact remains: HDMI or Component cables make no difference . . . PERIOD!!!!Here's the point: the OP is wondering whether he might get a better picture with an HDMI connection. The answer is "yes, he might". The cable is only one factor in the equation.

Hey genius , as an engineer, you should cover all your bases.

Component cables may NOT work for 1080p as there are a LOT of TV's that dont accept it over component.

That's not correct either. The OP never made any such query.
That issue was raised in a very convoluted manner by two responders in post #s 9 & 10.

In another part of the BJC article, they also write "There will often be significant differences between the digital and the analog signals, but those differences are not inherent in the connection type and instead depend upon the characteristics of the source device (e.g., your DVD player) and the display device (e.g., your TV set)."

It should be further noted that the BJC article is quite old, and since its writing, both source and display devices have improved considerably. The consensus on this forum over the past two years or so has been that there is no perceptible difference in picture quality between HDMI and Component connections.

As for your claim that your calibrated HDMI connection is "considerably better" than your calibrated component connection -
sure it's possible, but could be that something else is "wrong", since the consensus (on this forum anyway) has been that should not be the case.

As an engineer, I believe I did.

It should not take a genius to realize that when I wrote,
"if they did provide 1080p output, component cables would be capable of delivering the signal and perfectly suitable."
I did NOT say that the connection "would work", only that the component cables "would be capable of delivering the signal".

Even most non-geniuses pretty well understand that the display device must be capable of accepting the transmitted signal or it ain't gonna work.

That issue was raised in a very convoluted manner by two responders in post #s 9 & 10. Splitting some hairs here about how the issue at hand got raised? Nonetheless, the issue itself remains whether an HDMI connection from the cable box might look different than an analog connection.

In another part of the BJC article, they also write "There will often be significant differences between the digital and the analog signals, but those differences are not inherent in the connection type and instead depend upon the characteristics of the source device (e.g., your DVD player) and the display device (e.g., your TV set)."Yes. Since you are now quoting this article, I gather you agree there may be differences in digital vs. analog picture quality depending on the processing in the source device and display. That's the only point I am trying to make - that it's not possible to say an anlog connection will always look the same as a digital one.

It should be further noted that the BJC article is quite old, and since its writing, both source and display devices have improved considerably. The consensus on this forum over the past two years or so has been that there is no perceptible difference in picture quality between HDMI and Component connections.I don't recall seeing any substantive information in the last few years describing how device improvements have equalized the analog-digital playing field. Comcast cable boxes haven't gone through any technological revolutions in the last few years. If you have specific information in this area, please share it.

As for your claim that your calibrated HDMI connection is "considerably better" than your calibrated component connection -
sure it's possible, but could be that something else is "wrong", since the consensus (on this forum anyway) has been that should not be the case.Anything is possible. I suspect the vast majority of people have something wrong with their set-ups.

So, at the end of all this, what is your advice to those who want to know whether there might be a difference in picture quality between analog and digital connections on their equipment?

Typically what I see on this forum is people claiming that one (usually HDMI) will or should look better than the other -
which is a completely erroneous claim.
I agree that "it's not possible to say an analog connection will always look the same as a digital one".

I don't recall seeing any substantive information in the last few years describing how device improvements have equalized the analog-digital playing field. Comcast cable boxes haven't gone through any technological revolutions in the last few years. If you have specific information in this area, please share it.
As I posted earlier, almost without exception, those who have posted on this forum, many using Motorola boxes, report that they are unable to see a difference in picture quality when switching between HDMI and component connection.

So, at the end of all this, what is your advice to those who want to know whether there might be a difference in picture quality between analog and digital connections on their equipment?
I would still say not to expect any difference.
But by all means try both connections keeping in mind the importance of comparing properly calibrated inputs.
