How Many HDMI Ports Does Your HDTV Have?

harryk asks: "Ok, this is a serious question and one I don't think has been covered, at least not with a quick glance in Google's direction. With all of the media center components that we'll all have in our entertainment racks, the biggest question that I have (actually my wife prompted me on this) is how many HDMI ports does your TV have? With the PS3, my HD-DVD player or up-convert DVD player, and my fancy schmancy new cable box or satellite receiver, how on earth will I connect all of them?"

      Use component. HDMI enables HDCP and *that* isn't something you want to do.

      HDMI doesn't give you anything hugely useful. It can incorporate audio into the same cable with the video, however, for most people who have separate surround systems, this is an inconvenience, rather than a feature. Digital audio needs to go to the surround system, while video, component preferably, goes to the display device. If you're using your display's built-in audio, you're almost certainly involved in a sub-par overall experience

      Component, thus far, is the best of the best. Good (by which I mean just good... not stupidity like monster overkill) cables will give you excellent results. How do I know? Because I have a 22-foot diagonal display sourced from a 1080/1920 projection system. Component gives single pixel resolution without any trouble; that's awesome at that amount of detail.

      Remember: HDMI is bad and supporting it is the last thing you would want to do. HDMI enables HDCP, and HDCP is a pond-scum mechanism for DRM / copy protection.

      HDMI isn't bad anymore than the DVD player connected to your projector. It's a cable package that combines digital video and audio signals.

      HDCP is a method of encrypting the DVI signal transmitted over an HDMI cable. DVI cables, as well as monitors and video cards that have DVI ports, can transmit an HDCP-encrypted signal just as well.

      HDMI cables are handy if you have a reciever with multiple HDMI inputs--fewer cables to deal with.

      Is capturing a DVI signal and then recording it something you want to do? I don't think so.
      HDCP protects a DVI signal. That has a very high bitrate and it takes quite some effort to compress it back into the recorded material.
      When you want to record something, you record the MPEG2 (or whatever compression standard) material, not the decoded output.
      So, HDCP is not really a problem.

      Component, thus far, is the best of the best.

      Why do you consider Component the best? What was wrong with RGB that it needed to be replaced?

      That's why I suggest people support component. Digital channels are being misused. Analog is a great deal more difficult to screw up, and since component historically has not had encryption, it's almost impossible to mess with. I wasn't saying that only HDMI was bad; I was saying that HDMI was bad, since that was the topic, and then suggested a realistic, non-DRM infested replacement. I'm perfectly ready to stipulate that DVI is bad as well, if that'll make you happier. :-)

      Is capturing a DVI signal and then recording it something you want to do?

      No. Not personally. Though I see no reason why I should be prevented from doing so; copyright wasn't designed to support such restrictions. Capturing a component signal is something I hope to do, though.

      HDCP protects a DVI signal.

      No. HDCP doesn't "protect" the signal. It was never at risk. Saying it "protects" it is misdirection and hyperbole. What HDCP actually does is prevents the end user from (for instance) time shifting, recording for personal archival recovery, capturing the news on one's wedding day, you name it, it is in the way. DRM is not "protection", it is an insult to the consumer. It says "we assume you are a lawbreaker, and that you will violate copyright." It is presumption of guilt by fiat, the condemnation of one individual because of the acts of another (if it is even that), and nothing you can say will lift it one centimeter above those miserable goals.

      Why do you consider Component the best?

      It is the best generally available to the consumer. As far as RGB goes, one thing wrong with it is that the color gamut available isn't realistically broad with RGB or any other three-axis system you can name (and of course, that includes component.) Another is that RGB isn't generally available, so it's not really relevant to the issue at hand. Likewise, no 4 or greater axis system is generally available, and so that (again) leaves us with component. Component has the agreeable characterisic of being recordable with three high-speed A/D convertors, or as a triple analog stream if media were to become available that could accept three channels of such dense data. Good analog recordings have many merits. Digital have some too, of course, but unfortunately the industry is mostly using digital to screw the consumer, so I'm inclined to bypass them at this time as best I can, and suggest the same to others. At the moment, HD 1920 by 1080 is the top end, and component works just fine for that. So there is no need whatsoever for HDMI or DVI in the HDTV space. The industry can (and probably will) make an artificial need by intentionally degrading the component signal; such plans are, I hear, in the works. I have one word for that: Despicable.

      In Europe this concept has already been proved previously using the SCART or Peritel connector. Devices with these sockets tradtionally have two of them, and when the device is off the signal is passed through from one socket to the other with supposedly no degradation.

      I can tell you now, MOST homes in the UK are currently daisy chaining their Cable/Sky box through their DVD player/recorder into their TVs via several SCART cables.

      So, no, HDMI chaining isn't silly, it's a damn good idea.

      On a personal note, I have a very large and powerful A/V Amp - all my devices connect to that with one cable going from it to my output device (a Panasonic Projector). The Amp does all the video/audio switching for me ( as well as providing 7.1 DD/DTS kick ass sound :) ).

    My "TV" is a projector with HDMI input. The receiver is an upsampling unit that has two HDMI inputs, a series of component inputs, and the obligatory s-video and RCA inputs. It upsamples whatever it gets from non-HDMI sources and shoots it up to the projector.

    The two HDMI inputs I have are the HD-Tivo and the DVD player. I hooked a PC to the component input, but the upsampling process made the display fuzzy. I'd get a video card with HDMI output and try that, except both of my HDMI inputs on the receiver are used up. You can buy "hubs" to multiplex the HDMI, but they are very expensive.

    Sigh. My next A/V system will have to have 3-4 HDMI inputs, one for the computer, and possibly one for (the as yet unpurchased) HD-DVD player.

    Guess that's the cost of being an early adopter.

    You'll still need an audio mux (I like the 1177), and it doesn't look like AA's cheaper DVI switches support auto-switching, which is disappointing. Still, the IR remote should be convenient enough.

    The only benefit to the Gefen item you linked is that it ships with cables for $350, while the AA is cableless at $350. Not that it really matters, since you'll still have to buy an HDMI to DVI cable to use either of them with HDMI sources and outputs.

    considering the D in HDTV might as well stand for DRM with the rediculous number of restrictions most people will have to deal with, most intelligent slashdotters are doing a hard thing for nerds, theyre boycotting them.

    Already hundreds of thousands of early adopters have been burned because the so called "image constraint" or "down-rezzing" token will reduce their picture quality on most major HD media even though they were promised full resolution.

    Even tv's which were promised as fully drm compatible by hollywood and their manufacturer lapdogs mere months ago are being relegated to this ever growing list of "noncompliant" hdtv's which will never really be allowed to display true HD content.

    Considering the distinct possiblity that the standards will be changed again in another few months as they have been umpteen times in the past (as the DRM get's cracked before it's even fully off the shelf), the idea of laying out thousands for a supposed "HDTV" set seems less and less compelling.

    Add to that the fact that each standards change will result in an increasingly huge maze of expensive and heterogenous cables and the likelihood that the license terms for any newer standards will require compliance with "broadcast flags", at least on cable and satellite, then youre basically paying them to ship off your convenience, time, and fair use rights wholesale.
