CABLE CONSIDERATIONS FOR 1080P/50

Have you heard about 1080p/50?  This is the ‘next step' in video.  It is double the resolution, and double the bandwidth, of 1080i or 720p HD-SDI.  Surprisingly, it is sowing up on the consumer side more than it is on the professional side.  You can easily buy an LCD or other display, or a projector, that will show 1080p/50.  You can also buy a BluRay player that will produce a 1080p/50 signal – assuming you inserted a 1080p/50 disc.  There are a few dozen of those available.

 

One thing that doesn't exist is a  way to broadcast such a signal.  Oh, the standards groups are working on it.  And, hopefully, what they finally produce will be backward-compatible with SD-SDI and HD-SDI.  1080p/50 is sometimes called "3g" because is uses a 3 GHz clock producing a 3 Gbps data stream. (This is sometimes confused with 3rd generation "3g" cell phones.)

 

If you're interested in going to 1080p make sure it is 50 frame.  There are cameras that will also shoot 1080p/25.  While this is a standard theatrical frame rate, it is half the bandwidth of 1080p/50, back to the same bandwidth as HD-SDI.  But, you might well ask, why would anyone want to shoot in 1080p/50?  Well, there are a number of very good reasons.

 

REASON #1.  When 1080p/50 becomes a standard, everything you already shot in that format will be more saleable.  You can sell it again!  You can extend the life of the content you are producing.

 

REASON #2.  Murphy's Law says that, if you shoot today in 1080i, your first customer will want that content in 720p.  And, if you shoot in 720p, you will have a customer who wants 1080i.  You can convert between these formats, but not very well.  Especially with high-motion content (sports, racing etc.) it is extremely difficult to convert from one format to the other.  You end up with a tennis ball that is a yellow streak across the net!  But if you shoot in 1080p/50, you can down-convert to 720p or 1080i without losing anything, without software trying to figure out where that fast-moving content is going. So you can sell your 1080p/50 content as 720p or 1080i, and when 1080p/50 becomes commercially viable, you can sell it again.

 

The downside to 1080p/50 is, first of all, more expensive equipment.  This may change after a few years, but right now it's expensive.  And while there are inexpensive cameras (such as RED) that can produce 1080p/50, or even higher resolution, you have to add on equipment and software to record the signal, edit the signal, add graphics and so on. No doubt about it, 1080p/50 is an expensive alternate.

 

 

 

There are a number of camera manufacturers who offer their 1080p/50 cameras with dual-link cables.  That is, you simply use two standard HD cables to deliver the signal.  However, there are digital cables (such as Belden's entire line) which are tested and verified to carry an entire 1080p/50 signal.

 

When you analyze the 1080p/50 signal, however, you will see why many manufacturers of equipment and cable, cannot measure up.  The clock is 3 GHz, the data rate is 3 Gbps, but the occupied bandwidth (the Nyquist Limit) is half the clock (1.5 GHz).  To assure that this data will pass through equipment, cable or connectors, these have to be tested to the third harmonic of 1.5 GHz or 4.5 GHz. 

 

If you want to find out what the problem is, just talk to your local test equipment vendor and ask him for something to test 75Ω cable up to 4.5 GHz.  They will tell you there is no such thing…at least not at 75Ω.  Network analyzers and other test gear often go up to 10 GHz or 20 GHz or even higher.  But that's at 50Ω.  Testing a 75Ω cable as 50Ω is something less than accurate.

 

In order to get these analyzers to work at 75Ω means you have to purchase a balun, a matching network, to match the 50Ω analyzer to the 75Ω cable (or whatever you are testing).  And those are simply not available above 3 GHz.  So most manufacturers test their 1080p/50 products to 3 GHz, the second harmonic.  Again, not as accurate as you might wish.

Table 1

 

 

Manufacturers who wish to enter the real world of 1080p/50 must buy custom-built matching networks, which can cost many thousands of dollars.  And, if they only buy one or two, then obviously, they are not using these to test the cable except in the lab.  The best cables out there have every metre tested, not just an occasional test in the lab.

 

The one serious consideration with 1080p/50 system designs and installation, is cable distance. Table 1 shows the ‘safe' distance for 1080p/50 (SMPTE 424M standard).  Note that with smaller cables, these distances can be significantly short, requiring the use of larger cables.  However, these distance are calculated from the SMPTE formula that states, when the signal is down -20 dB at half the clock (1.5 GHz), that's as far as the cable can go.

 

Many chip and equipment manufacturers complain about this limit and state, or show at tradeshows, cables going much farther, up to double the distance shown. This clearly shows that these distances are chip-dependent.  As chip designs improve, the distance achievable on any cable will also improve.  At the same time, manufacturing process for cable are also improving, so these distances shown are even more "conservative".

 

If you use this table, you will be very safe.  If you use the recommendations of chip or equipment manufacturers, be sure that you maximize the performance potential of every piece to maximize the performance of you system.

3D Technology Checklist This product is 3D-related. To help you get a great 3D experience, use our checklist below to ensure that you have everything you need. If you have any questions or want to learn more about 3D, we invite you to visit 3D 101--our center for everything 3D. To get started with 3D, please ensure that you have: A Display The first--and most important--item you'll need is a 3D-ready display--whether it be a 3D HDTV, 3D projector, or 3D computer monitor. These displays usually have a higher processing power than older models as they need to display one image for each eye to create a 3D effect. A Source While your display is ready for 3D playback, you still need a device to read 3D content (i.e., a movie or a show). This source can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3. Content In order to watch 3D, you will need to get some 3D content. This 3D content will come from the source mentioned above in the form of a 3D program, movie, or game. Please ensure that your 3D movies are in the Blu-ray 3D format, as this new format will provide the best 3D experience. 3D Glasses All 3D HDTVs on the market require Active Shutter glasses to create the 3D effect. You will need to buy one pair of glasses for each viewer. Also make sure that the Active Shutter glasses you buy are compatible with your display--for example, buy the glasses from the same brand as your 3D HDTV. HDMI Cable To connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a hgh-speed HDMI cable. Cables with this designation--with bandwidth speeds up to 10.2 Gbps (gigabits per second)--will be able to carry the 3D signal without any loss of quality. If you want to get more information about 3D, shop our 3D products, watch videos, or interact with other customers, visit 3D 101, our customer center about everything 3D.

With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience. If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get. Minimum size = Viewing distance/3 Maximum size=Viewing distance/1.5
