What is a HDMI Plasma or LCD Display Connection?  HD-SDI?

The '''High-Definition Multi-media Interface''' (HDMI) is an industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, DVD player, and A/V receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV).  Panasonic Plasma Displays, 42 inch TH-42PHD8UK

HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It is independent of the various [[digital television]] standards such as [[ATSC]], [[DVB]](-T,-S,-C), as these are encapsulations of the [[MPEG]] data streams, which are passed off to a decoder, and output as uncompressed video data, which can be high-definition. This video data is then encoded into [[TMDS]] for transmission digitally over [[HDMI]]. HDMI also includes support for 8-channel uncompressed digital audio. Beginning with version 1.2, HDMI now supports up to 8 channels of one-bit audio. One-bit audio is what is used on [[Super Audio CD]]s.

The standard Type A HDMI connector has 19 pins, and a higher resolution version called Type B, has been defined, although it is not yet in common use. Type B has 29 pins, allowing it to carry an expanded video channel for use with high-resolution displays. Type-B is designed to support resolutions higher than 1080p.

Type A HDMI is [[Backward compatibility|backward-compatible]] with the single-link [[Digital Visual Interface]] (DVI) used on modern computer monitors and graphics cards. This means that a DVI source can drive an HDMI monitor, or vice versa, by means of a suitable adapter or cable, but the audio and remote control features of HDMI will not be available. Additionally, without support for [[HDCP]], the video quality and resolution may be downgraded by the player unit. Type B HDMI is similarly backward-compatible with dual-link DVI.

The HDMI Founders include leading consumer electronics manufacturers [[Hitachi, Ltd.|Hitachi]], Matsushita Electric Industrial ([[Panasonic]]), [[Philips]], [[Sony]], [[Thomson SA|Thomson (RCA)]], [[Toshiba]], and [[Silicon Image]]. Digital Content Protection, LLC (a subsidiary of [[Intel]]) is providing High-bandwidth Digital Content Protection ([[HDCP]]) for HDMI. In addition, HDMI has the support of major motion picture producers Fox, Universal, Warner Bros., and Disney, and system operators [[DirecTV]] and [[EchoStar]] ([[Dish Network]]) as well as [[CableLabs]] and Samsung.

(Serial Digital Interface) A physical interface widely used for transmitting digital video in various formats. For electrical transmission, it uses a high grade of coaxial cable and a single BNC connector with teflon insulation. It also uses optical fibers with ST, SC and FC connectors.

Serial Digital Interface (SDI) is a standard for digital video transmission over coaxial cable. The most common data speed is 270 megabits per second (Mbps). However, speeds of up to 540 Mbps are theoretically possible. Standard 75-ohm cable is used. This is the same type of coaxial cable used in most home television (TV) installations.
The SDI standard uses data words that are 8 or 10 bits in length. Signals are uncompressed and are self-synchronizing between the source (transmitter) and destination (receiver). Most errors caused by noise or interference can be detected, and the lost data recovered by means of a specialized code called the Hamming code. A signal in SDI can contain up to four independent digital audio signals along with the video signal.

If your still not convinced about plasma screens,
then take a look at how they compare to other display technologies.

How the Plasma Screen works
The Plasma Television uses thousands of glass, sealed chambers containing a mixture of neon and xenon. The chambers are in front of colored phosphors. Each chamber has three phosphors, one red, one blue and one green. When these chambers are in use they emit invisible UV light that excites the phosphors on the rear display glass enabling them to produce light that can be seen by us.

Why choose a Plasma TV?
Among the many benefits of renting a Plasma TV screen the, perhaps, primary attraction is that due to the innovative lightweight and slim design the TV can be hung from the display walls or placed on a tabletop, canceling the need for an extra display unit and enabling large audio visual displays in places where a conventional TV would use too much space, or a projector would be impractical.

Plasmas perform extraordinarily well under most ambient light conditions. Very bright light does not wash out the image on the screen. The beauty of these flat screens is that, unlike front view projection screens, you don't have to turn off the lights to see the image clearly and easily. Therefore, plasmas are excellent for video conferencing and other presentation needs, which require the lights to remain on.

Another characteristic of a plasma panel is the extreme viewing angles both vertically and horizontally. With 160 degrees viewing angle, people sitting off to the side of the plasma screen will still be able to see the image without losing any of it.

Plasmas tend to be very lightweight in comparison to similar sized standard display monitors and television screens.

No existing display system can compete with the low depths available in plasma panels. The thinness of theses systems allows for the monitors to be placed virtually anywhere. Some plasma panels are known to be as thin as 3.5 inches deep.

They can be hung on walls, mounted to ceilings, flush wall mounted or placed on a tabletop. Many mount manufacturers are designing more creative ways to mount plasma panels because of the ease of engineering involved.

Plasma panels are also not affected by magnetic fields.

Plasmas are easy to use. Almost as easy as plug and play. They tend to accept inputs for both data and video (industrial models). The main issue is resolution. Be sure to find a panel that works with your resolution needs. All will show standard VGA (640x480) and some will accept signals all the way up to UXGA. (UXGA is a video resolution that supports a max resolution of 1600 horizontal pixels by 1200 vertical pixels)

Screen size
Most plasma screens are in the 42-inch category, but a greater variety of screen sizes are emerging, including 20, 30, 37, 40, 50 inches and our largest screen at 61 inches.  These screen sizes are a measure of the diagonal dimension of the screen, so a small variation in this vital statistic can make a big difference to the actual screen area, as the diagram below shows us.

Aspect ratio
This is the ratio of the screen width against the screen height. The majority of screens have 16:9 aspect ratio, which is the normal ratio for widescreen TV. Manufacturers are now adding more 4:3 ratio screens to their ranges, which is the normal ratio used by PC monitors and standard televisions. See 20, 23, and 30 inch LCD flat panel display or the  Hitachi 37 Inch Plasma Display. If you are connecting a plasma screen to a PC, you can still use the widescreen format. Your PC can often be set to use the 16:9 ratio instead of 4:3, or the image can be stretched to use the whole screen.
If you're connecting to a video source, a 16:9 plasma screen is ideal for widescreen films and can still display signals from sources that use a 4:3 ratio by stretching the image or by displaying the image at its natural size using a portion of the screen.

Simply put, this is the number of pixels available on the screen. The higher the resolution the greater the definition and sharpness of the image when projecting from a computer. This is more important with larger screens where the pixel size is more noticeable, and less important when displaying images from a video source because rapidly changing images make the pixilation less noticeable.
When choosing the correct resolution for you, take into consideration your most frequently used application.
SVGA (800 x 600) is okay for most video and large text presentations, but doesn't have amazing sharpness and is less suitable for small text and intricate graphics.
XGA (1024 x 768) is the most popular choice for presentations and high quality video.
Resolutions higher than XGA are aimed more at specialist applications or high definition TV.
If you're using a PC with your screen then it's best to check that the screen is compatible with the resolution you use on your PC. The resolutions that the screen supports should be stated in the screen's brochure (which is available in Acrobat PDF format in the 'Buy' section of our web site).

Contrast ratio
The contrast ratio is the measure of the brightest luminance the screen can achieve against the darkest luminance. The darkest luminance is important to the image because blacks will be truer to their real color, rather than appearing grey and washed out.
You can use the contrast ratio as an approximate measure of how the image will appear in different lighting conditions. The higher it is, the better the contrast, although the measurement process is open to some different interpretations by different manufacturers.

Measured in candelas per square meter (cd/m²). This is not quoted by all manufacturers, but is a selling point for others, so it's difficult to compare screens based on brightness alone.

Thinner plasma screens, while looking smarter, are more suited to environments where space is an issue, such as exhibition stands.

Display area
This is the measurement of the screen area itself not including the bevel.

Picture-in-picture / split screen functions
A feature on some plasma screens that allows you to view images from two different sources simultaneously. For example, you could show a video seamlessly within your PC presentation.

Wall mounts and  stands
Most plasma screens don't come with any form of mounting, so you'll need to allow for this in your budget. We supply table stands, wall mounting kits and other mounting accessories Call us for more details.  Dual pole adjustable (5.5 feet  to 3 feet ) from $75 per day

A few plasma screens come with built-in speakers, but most sell them separately. The speakers provided by the manufacturer are generally the best looking speaker option available, as they're designed to match the screen itself. You'll usually get the option to control the audio volume using the remote control as well, whereas if you were using speakers directly from your source you may not have this option unlike conventional televisions, Plasma screens are not affected by magnetic fields.  Speakers from $50 per day.

TV receiver
A plasma screen isn't quite like a TV - it doesn't include an aerial lead to plug into the wall and start receiving TV pictures. If you want to use the plasma screen for television, you'll need to either pass a TV signal through a video recorder, or purchase a separate TV receiver unit.  DVD, VCR Combo form $45 per day.

Due to their size and the amount of exposed thin glass, plasma screens are more than a little prone to breakage during transportation. If you do smash the glass there aren't any repair options available to you, so if you are taking yours on the road frequently, the packaging the screen is sold in won't last forever. For the best protection, ask us about our flight cases.  Plasma Display Shipping Cases from $160 per week.

Plasma Screens compared to other technologies

What is Plasma?

Plasma screen technology consists of two glass panels approx. 0.1mm apart that compress thousands of tiny pockets of gas called pixels. Each of these pixels also contains colored red green & blue phosphor.

When a current is applied to each pixel, the gas inside reacts to form a state of plasma and Ultra Violet light is produced. This UV light reacts with the colored phosphor to produce a range of up to 16 million colors on the screen.

As all of the pixels emit light at the same time so there is no screen flicker unlike traditional display technologies. There is no back lighting or electron beam so the image is much sharper, brighter and consistent from edge to edge.

Why choose Plasma?


Larger viewing angle, 160º compared to LCD 40º & rear projection 120º. (Allows a larger audience to be able to view the image reproduction)
No projection throw distance limitations.
Brighter & able to tolerate higher ambient lighting. More accurate & distortion free images. (As plasma screens are flat, unlike the curve found with standard televisions, this eliminates the edge distortion that can occur on curved screens).
Universal Display Capability. (Most plasma models are able to accept video format. Typically they will include composite video (NTSC & SECAM), S-video & component video inputs, plus one or more RGB inputs to connect to a computer).
Digital technology.
Unaffected by magnetism. (Unlike conventional CRT displays, plasma screens do not use electron beams and so can be placed near loud speakers with out suffering any distortion).
Thin Profile to save on space - 3-6.5 inches thickness
Free standing or wall/ceiling mountable

Compared to CRT
Clearer sharper image.
Uniform brightness across the whole screen (no faded edges). (A CRT television will have what is known as a hotspot, where the picture is at its brightness, and then will fade out the nearer to the edge).
Flicker free images.
Consumes less power (some come with an ECO-mode).

Compared to LCD
Brighter viewing angle.
Better colour quality.
Higher contrast ratio.
Better picture.

What do I need?
Plasma screens from any manufacturer can be connected to a video source (VCR), TV, DVD player, satellite system or a computer. Most plasma screens don't have a built in TV tuner so for a terrestrial TV signal, a connection to VCR is required.
You can connect more than one device to a plasma screen at any one time so you can swap between a PowerPoint presentation and a video clip using the plasma screen's remote control. Switch boxes are also available that allow several computers to connect to a plasma screen at once. On the switch box is a button for each input computer, which when pressed, will show that computer's display on the plasma screen.
Some plasma screens also have split-screen and picture-in-picture options. This can be used to display multiple video clips or presentations on the same screen at the same time.

How long will they last?
This varies considerably between manufacturers but usually from 20,000 to 30,000 hours. After this time the plasma screen will only be at around half the original brightness. If you used your plasma screen for 5 hours a day every day it would last over 10 years.
At the end of the plasma screen's life, the screen will be very dull and you will need to replace the plasma screen with a new one. This is one advantage plasma screens have over LCD projectors, which have a bulb life of usually 2,000 hours before replacement.
