Is 2007 the year of the display format wars? A look at the licensing structures of these formats reveals more

Unfortunately, consumers will be faced a total of three display standards in 2007 -- and even more in 2008. Along with HDMI, computers will start to ship with DisplayPort and the Universal Display Interface (UDI) this year.  UDI is electrically compatible with DVI and HDMI, but does not carry the same licensing fees as either and has a stripped down feature set.  DisplayPort is not compatible with any existing signaling format.

One of the primary concerns for these new standards is cost and interoperability.  Expensive HDMI and HDCP certification is cited as one of the culprits delaying AMD 690G motherboards.

High fidelity signaling backers are split into two licensing camps: one supporting the DVI-derivatives (DVI-HDCP, HDMI, UDI) and the other supporting DisplayPort. AMD, Dell, Genesis Microchip, Hewlett-Packard, Molex, NVIDIA, Philips, Samsung and Tyco Electronics are supporters of DisplayPort; Hitachi, Panasonic, Philips, Sony, Silicon Image, Thomson and Toshiba compose the primary backers of HDMI. A significant portion of the DisplayPort supporters also have interests in HDMI.  Earlier last year, several manufacturers including Sapphire and PowerColor announced HDMI-enabled graphics cards based on ATI GPUs. MSI also announced HDMI cards based on NVIDIA GPUs.

When DailyTech asked why HDMI was taking a long time to appear in PC products, Leslie Chard, president of HDMI Licensing LLC, said "Right now most manufacturers are considering the cost of adding HDMI to their graphics products. Since HDMI is based mainly on DVI signals, the technology is already available in graphics processors. HDMI is everywhere -- consumer electronics, home entertainment and now companies are demanding the technology for smaller handhelds. You can't beat HDMI's cross platform compatibility."

Joe Lee, director of marketing for Silicon Image, added "Card manufacturers now only have to consider ways of grabbing the sound output through the PCI Express bus and adding the cost of the physical connector. If card manufacturers can finish writing the special [drivers] needed to grab the audio, everything would be set. Windows Vista should help drive HDMI forward."

According to initial reports, DisplayPort was heralded as a royalty-free technology. As it stands today, DisplayPort is royalty free but is composed with well over 200 patents. According to VESA, the committee that overlooks over the DisplayPort standard, the intellectual property (IP) holders are not held fixed and can and may charge a "reasonable" fee for the technologies used in DisplayPort.

Chard took a shot at DisplayPort, claiming "These IP holders are free to charge royalties under RAND [Reasonable and Non-Discriminatory] terms.  Until these IP holders make a public commitment, manufacturers have no idea what this rate will be.  Moreover, additional IP holders may come forward and charge additional royalties in the future; this is especially true if the DisplayPort standard ever evolves to incorporate advanced new technologies." 

HDMI's fees are already disclosed -- $0.04 per product and a small minimal fee for the HDCP keys, if used. HDMI Licensing LCC reduced the fees associated with using the technology late last year.

The largest hurdle DisplayPort faces, besides getting out the door, is interoperability with other devices.  DisplayPort is not compatible with HDMI, UDI or DVI.  The hurdle in jumping from one signaling protocol to the other is that the DVI-derivative protocols use HDCP, DisplayPort uses DPCP and HDCP.   VESA partners claim they will develop devices that allow HDMI to DisplayPort conversion, though doing so would mitigate DPCP.  Lee points out that this is essentially against the whole principle of a content protection protocol in the first place: if someone can freely negotiate between multiple or non-existent protocols that aren't under the same certification umbrella, then why have a certification process at all?

It has not been disclosed yet as to whether or not DisplayPort implementers may be required to pay royalties for the HDCP and Display Port Content Protection (DPCP) conversion either.

As of right now, the consumer electronics playing field is blanketed with HDMI-enabled products. The technology also recently entered its 1.3 revision, supporting features such as higher resolution and deep-color (wider color gamut) -- Sony's PlayStation 3 supports HDMI 1.3.  Philips, the inventor of DisplayPort's content protection scheme DPCP, recently announced a wireless version of HDMI.

AMD is expected to launch DisplayPort compatible GPUs later this year with NVIDIA opting for the standard as well. Early last year, Silicon Image stated that UDI will end up replacing both HDMI and DVI standards on the PC when it becomes available to reduce licensing fees, though it will still be compatible with the older standards.

Format wars

Again with these stupid format wars. This is getting out of hand and I'm not going to have anything to do with any format till there is a universal standard.

I didn't invest in a 56k modem till K56FLex and X2 came together and made the .V90 Standard

I didn't invest in a DVD writer drive until dual format DVD drives were released that could handle both + and - formats

I'm not buying any Hi Def media until HDDVD and BluRay comes to some sort of agreement, one format leaves or another format takes over.

I'm not buying any HDMI, UDI or Displayport Devices until there is one format.

So you don't have ANY HDMI or DVI devices now? This is the first time I have heard about Displayport, but HDMI has been around long enough not to worry about that format. There were millions of HD displays sold for the superbowl and I expect all of them had HDMI. It is dumb to start working on a new format when HDMI has such a hold on the market and there really isn't a reason to switch other than price.

Oh well I forgot my family bought a 52 inch plasma last summer with HDMI. We only bought it cause we all though HDMI would be the only cable format. But since we don't own anything that else that uses HDMI we don't use those ports.

I was planning on upgrading my crappy computer monitor once HDMI monitors and video cards became available but now that they are releasing 3 competing formats I think I am going to stick with DVI-D until this gets resolved.

Although I think you are wise to hold off for a while, waiting for a universal standard will keep you likely waiting forever.

I have a Blu-ray burner for no other reason than it was at no cost to me, but I have yet to use it for any non DVD/CD applications. My widscreen moniter supports HDCP, but my 7900 does not. I don't have Vista.

The fact is I have a lot of pretty recent hardware (CD2 4MB, 750GB HDD [broken] + Raptor as well) and yet because of a few barely missing links, the next generation video formats are completely lost to me.

I like HDMI, it works well for my HDTV and upconverting DVD player, but the cables are bloody expensive. Wireless HDMI sounds nice, but when will it arrive, how well will it work and how much will it cost?

Its interesting both graphics camps are on the DisplayPort side (probably for money reasons), and if they are how will they work with my DVI monitor?

The combination of next gen optical and display wars leaves me with no clear picture of my upgrade path, or even if any of my current equipment will be of any use to me in two years.

That said, my current computing experience is quite nice, and so I'm glad I went with something.

There are several major reasons why Display Port is a much better connection for PC's then anything else currently on the market today. HDMI was and is designed to be a A/V Superlink and it is NOT consistent with Computers and PC Display devices future demands of the industry. Nvidia and ATI know EXACTLY what they are doing. Display port is made specifically to be the best possible solution for future PC display properties.

For FACTS... goto the following link, there is also a comparsion chart for ALL 4 major future display connections and you will clearly see Display ports advantage in several areas.

You will find all the information you need to on Display Port, which I think quite frankly... needs to be the most supported, especially if you value the best possible performance for present and future computer needs.

That site does not make any compelling argument for why UDI is better than HDMI. It gives you some number tables which are generally meaningless. Five gigs of "raw capacity" (whatever that actually is) versus Seven gigs equates what in real world performance? They don't say.

Adopting this is a stupid decision by manufacturers hoping to skimp a few cents off production and up their profit margin by .02%. HDTVs have already embraced HDMI as the standard. Windows is pushing the PC as an AV platform with things like Windows Media Center and so on. UDI goes against the trend of unifying PC and TV, and generally causes more of a headache for people buying PC monitors.

HDMI is here to stay. If you want your laptop to double as a DVD-player for your big new HD flatscreen, UDI is not going to help you. HDMI for all computers is a step in the right direction, towards a convergence of devices; UDI is a step away from that direction and a foolish one for manufacturers to embrace.

You will notice that the example I used above is their most touted feature, notebook support because it can be incorporated into integrated graphics solutions. That's all fine and dandy--show me an HDTV with UDI and I'll reconsider my argument. For now, a much better use of time and money would be making HDMI fit on a motherboard rather than giving us another video standard to try and remember and account for when shopping.

Obviously you have made no point to actually read the website otherwise you would know the “clear” advantages Display Port has over HDMI. If for some reason that website doesn't provide enough information for you, then you can go to VESA's homepage which is linked on above noted webpage for MORE information. Also, you are talking about UDI, your out of the loop. The website I listed is a website about “Display port”, which is a better technology then UDI as Display Port meets more certain specifications that VESA implies for FUTURE PC and Graphics use. Which means that while true, there is no use for the new technology now and HDMI might do for now, but Display Port will be able to output at much more bandwith and at specific frequencies, something HDMI cannot do and as time goes by, Display Port will be more heralded as the connection of choice as it will be needed and recommended for PC and definitely professional use. Also, HDMI is not here to stay in the PC realm, as there are in fact additional format connections that will become available this year... such as UDI and Display port, however since both Nvidia and AMD BOTH support Display Port, this will most likely become the next common standard for Display technology for pc's and rightfully so.... Get the FACTS before you shove meaningless personal opinions out in the wild.

The whole point of this article is that HDMI will not last as an official PC standard. Its here now as an additional connection, but won't be for long as a common more advanced and easier to manufacture connection for PC use will most likely take its place.

I assumed incorrectly UDI was equivalent to DP, my argument was about VESA's page and your assertions on DisplayPort, not UDI. All of my references to UDI were made under that assumption.

"Get the FACTS before you shove meaningless personal opinions out in the wild."

Don't get uncivil with me. I got the FACTS from the website you listed. Nothing you mentioned addresses my argument. Why don't you explain why it's better to differentiate the PC monitor/HDTV market if you really want to disprove my post. All of the numbers cited in your site seem rather meaningless given the absolute lack of real-world results. Those are the sort of things a consumer is interested in.

"Display Port will be more heralded as the connection of choice as it will be needed and recommended for PC and definitely professional use."

Stuff like that, now that strikes me as a "personal opinion" more so than anything I said. Now instead of antagonizing me why don't you make a reasonable argument?

So far the only point you've made to counter me is:

"Display Port will be able to output at much more bandwith and at specific frequencies, something HDMI cannot do and as time goes by"

Why don't you explain what that means to us less technically-minded people instead of talking in floaty hypotheticals about why DisplayPort is the best? Does it really matter to have more bandwidth at specific frequencies? What does it mean about image quality, color contrast, refresh rate, etc.? All you are doing is playing the same numbers game the site did.

Even assuming that DisplayPort is the magic bullet to all our PC monitor woes, why is better to use it as a standard than to try and converge the HDTV market with the PC Monitor? As I stated before, this is one of Windows' primary targets of interest with Windows Media Center.

See if you can be civil and mature with me this time.

I agree, although you made it obvious you didn't read the Dailytech article by not knowing UDI and DisplayPort were not synonymous.

The chart on the site linked went out of its way to make very similar features between HDMI and DP look bad for HDMI and good for DP. This is not surprising as the site's goal is to promote DP.

I like the fact that VESA is behind DP and it very well may be a better interface in the long run, but it remains that DVI has yet to even enter the mainstream.

VGA and its analog derivatives are by far the most used interfaces for video. Even now with Vista, HDCP, Blu-ray, etc I'd gather that most PC's being sold today are sold with analog VGA interfaces ONLY.

VGA has lasted 20 years and is still a good interface. What the industry needs is another VGA. If that standard is DisplayPort, than I'm all for it, but it will mean that every DVI based standard will merely be a footnote in display standards.

I guess my main gripe with DisplayPort is that I disagree with their main objective. Consumer Electronics devices should NOT use a different interface than Computers.

There happens to be a great many "VGA's" it's just, they were all compatible with similar cables. The Spec of VGA that you use is based on your resolution. VGA refers to a resolution of 640x480, SVGA refers to a resolution of 800x600, XGA is 1024x768 and so on and so forth. The db-15 display port may be 20 years old, but the standards you currently use are not.

You may be completely right on the best PC port. HDMI wins hands down when it comes to being accepted over all electronic market. Either way I want a real world solution.

Really when it comes down to it I would want a graphics card with both. Display Port for monitor, and DVI for my DVI to HDMI cable to go to my TV. This way it's the best of both worlds. Considering how much new graphics cards are anyway, I have no problem paying up to $30 more to work with my current monitor and my HDTV.

P.S. I really don't get combined high quality/res cables for sound and video. If you really need the high quality, they aren't going to be going to same device. Like video from HD-DVD/Blu-Ray/Graphics card to TV/Monitor and sound from HD-DVD/Blu-Ray/Sound Card to Receiver/speakers. (Yes, you could route everything through one item, but middle man can only hurt you. Why not just go to source?)

Duh... my brain was stuck on my first point when I wrote that. Ignore it. Wish I could edit things after the "post" command which I hit almost instinctively (other forums I'm on allow both previewing and editing after the fact).

As to why wanting integrated audio (for the other person's comment), HDMI is used on things like TV sets where audio matching the video is helpful. Many big wigs think TV sets should be "replaced" by our desktop computers (kinda) so connections to the computers should also have integrated audio so it can hook to the HDTV set as part of that system. I personally would rather have separate systems that at best have a link, but those in the computer market, like Microsoft, want to get into other markets so they can expand. Rather than "jump" into another market, they're trying the Borg methodology instead. :-)

"VESA claims it will develop devices that allow HDCP to DPCP conversion."

Displayport SHOULD be doomed right there. That looks like the sweetest, most likely place ever to intercept an HD signal and unencrypt it as it moves from one format of encryption to the other. I can see lots of fighting on the horizon over that one.

4c per unit is NOT an extortionate amount to be paying in licensing fees on multi hundred dollar video cards with HDMI and HDCP.

Still, it seems all the major PC players (without mention of Microsoft) are backing it including both video chipset makers so that could be all it takes.

I just dont see how any one of these companies cant take a subtle hint (like a really heavy brick in the head multiple times sort of subtle hint) that there isnt ONE consumer that is at all happy about these stupid format wars, nor does it help any of their businesses in the slightest.

Isnt it interesting in THIS argument we see one of the very rare times that both Sony and Toshiba are on the same side - HDMI out on both Blu-Ray and HD-DVD units ring any bells anyone?

With DisplayPort, you don't know the price, if any, of the royalties. Could be 10 cents but with a lower license fee.

AMD and NVIDIA aren't idiots. If they are backing DisplayPort over HDMI, there must be a good reason. I, too, would just like to see HDMI take over, since it doesn't seem unreasonable, and it's already widespread, and I like the idea of home theater and PC equipment sharing a common connection. But like I said, there must be some particular reason AMD and NVIDIA are backing DisplayPort, and considering they run the graphics industry, I guess that's just what we're going to have to deal with. I am very interested in knowing their reasons for picking that standard, and when cards and monitors will be produced with that standard.

Not to worry, though. Regardless of these little tech battles the big companies MUST cater to their customer. So rest assured if you buy a new video card, it WILL have the latest connections on it, and a new monitor will most likely match it, and there will almost definitely be all types of converters for any older displays.

What exactly do you mean by "worked in the industry"? Do you mean retail stores or do you mean an engineer at a company like AMD? ;) I have done the former, obviously not the latter.

But I generally agree still with what I said. Most of the time, regardless of new technologies or competing standards, things trickle into the market at a slow enough pace for your average consumers at Best Buy to adapt. And they won't all of a sudden start making video cards without any DVI connection, or monitors with ONLY UDI or DisplayPort connections. And yes, adapters will exist. VESA even admitted to the HDCP to DPCP converter, and that is probably the most unlikely candidate to have a converter available.

A lot of missing pieces.

I could only wish Dailytech actually do more research into the topic.
Intel was not mention in the position of UDI, HDMI and DPort. Intel 's subsidiary was the inventor of HDCP. And previously Intel has been on the HDMI side supporting UDI as PC's Display standard.

However in CES 2007 both Intel and Samsung announced they are also behind the DisplayPort standard which several new post stating UDI is essentially dead with only Silicon image behind UDI.

Few report also stated that DisplayPort, is actually cheaper to produce not only due to liscense fees but also circuit design simplification.

One of the new info from Dailytech is the concern of DisplayPort IP and patents involved. I hope we will hear more on the issue.

One of the thing i still dont understand is how will Audio work out in this scenario. Any explanation would be great :) Grabbing Audio Signal from PCI express? I could only imagine the audio signal is Digitally transfered all the way to a decoder at the end of the HDMI / DisplayPort cable before it is converted back to Analog signal again.

This makes sense in TV and living room where there is a HDMI hub to split signal and diverted Video to TV and Audio to Amp. But obviously PC user dont want another hub sitting there. Since speaker are positioned relative to the monitor instead of mainly PC so it make sense having audio cable output directly from the monitor. This would also mean the power supply for monitor could also handle the power for speakers as well. One less power cable to worry about.

But that would makes DAC and audio signal being processed at the monitor?
( Sorry if i have make it sound complicated )

And to reply about DPHP to HDCP. DisplayPort version 1.1 has support for HDCP already.

I think AMD and Nvidia or creating/supporting an alternative interface with an upfront interface licensing fee VS an upfront licensing fee plus hefty back end device licensing fee. HDMI charges $0.04 per interface plus $10000 (or was it $100000) per device(taken from posts in this article I will trust at face value) AMD and Nvidia want an alternative that charged solely on the interface. It is difficult to create an affordable low cost part when you are slammed with such an unreasonable fee. Product development will suffer, because if you create a niche market item like All-In-Wonder you are stuck with the hefty device fee. Where as, if you charge a per interface fee then the number of products that you sell determines the licensing fee, not the number of devices you design.

AMD and Nvidia may just threaten to support this new interface to force HDMI to rethink their licensing model to allow better innovation, or reduce production licensing, or both.

HDMI needs to be reworked to allow seperate Audio and Video. Really most of us who have a HDTV also have a multi channel surround sound system to handle all the boomin glory of our movies and games. Keep things digital to digital and point to point. None of this daisy chaining. Else design a format that supports a single point for input and all devices connect to it (universal reciever with half a dozen inputs and a pair of outputs for video and sound to 2 different displays so you can watch 2 seperate signals on 2 seperate displays or PIP, whatever)

Seriously, these guys need to spend less time coming up with copy protection schemes and just work on what really matters Quality and speed. Cause in the end everything gets hacked anyway :)

I think I'm just going to stick with my plain DVI until the next generation interconnect thatfinally does away with all this "content protection" BS.
