HDMI, DVI and Component Cables Explained

Background:

As the HDTV market continues to heat up, consumers are in need of being educated on the latest technology in order to make intelligent purchasing decisions. There are a plethora of articles explaining the technical pros and cons of the 3 dominant HDTV display technologies namely: LCD, Plasma, and DLP. However, one all- important, but overlooked feature in selecting a HDTV set is the type of HD video connection. The video connections available for HDTV are: component video, DVI (digital video interface) and HDMI (high definition multi-media interface). We will discuss briefly the pros and cons of each.

Component video cable commonly referred to as R, G, B (Red, Green, Blue) actually consists of 3 separate cables because it distributes the 3 primary color components to the display. All colors can be generated from weighted distribution of each Red, Green and Blue color components. Of the 3 HD connection technologies available today, analog component video is the most mature technology.

-Advantage: Analog component video cable is mature and cost effective.

-Disadvantage: component video cables are analog! All HDTV sets are inherently digital therefore extra digital to analog and analog to digital conversion is necessary in order to process the video. This extra conversion can introduce video artifacts. Since all HDTV's are digital, it only makes sense to use an all- digital connection such as DVI or HDMI.

DVI (digital video interface)as the name suggests is an all-digital video connection. Unlike analog component cables the DVI interface transports the original digitized R,G, B video signals from the HD source to the HD display. Since it is all digital, no artifacts or degradation will be incurred. You will get EXACTLY the picture that the video source supplies with no degradation. DVI connection is often found on HDTV as well as PC video cards.

-Advantage : DVI is ALL-digital, so there is no picture degradation from source to display.

-Disadvantage : Digitizing R, G, B requires extremely high bandwidth. The aggregate data rate of the digital R, G, B signals is 1.65 Gbps! The high bandwidth means that cable quality is important and also the link distance is limited. Typical link budget for a DVI is ~ 15 ft.

HDMI (high definition multi-media interface) is the latest state of art audio and video connection. Technically, HDMI is identical to DVI with 3 notable differences. 1) HDMI is a much smaller connector (it looks like an U.S.B. connector), 2) HDMI utilizes copy protection called HDCP (high definition copy protection) and 3) HDMI carries multi channel digital audio. HDMI, like DVI, is ALL-digital therefore picture quality is "perfect" from source to display.

-Advantage: HDMI is a single digital video and Audio connection. Only 1 single cable is needed to transport both audio and video! This significantly reduces cable clutter behind your theater setup.

-Disadvantage: Like DVI, the link distance is limited and a high quality cable is required because of the inherently high bandwidth required to transport digital R, G, B. video.

Conclusion:

As the HDTV market continues to mature, consumers will need to be educated on the HDTV video connections available. We have outlined briefly the main features along with the pros and cons of each connection solution, so the consumer can make intelligent a choice in selecting the HDTV video connections.

What to Look for When Purchasing an HDMI Receiver

A sometimes overlooked element to a perfect home theater is the perfect sound system to accompany your viewing experience. While much attention has been given to which TV will offer the clearest picture, the brightest views, and the deepest colors, less attention seems to be paid to the sound quality that will accompany that visual experience. Some people are content to just have their standard television produce the audio for the image presented on the screen, but those people who are truly in the market for a true home theater experience know that this will never happen satisfactorily without high quality surround sound, and one of the first components that you will need when building that perfect audio setup is a receiver.

Since HDMI has become so popular it has been widely replacing the toslink and coaxial cables that most of us are very familiar with. When you are getting ready to purchase a new HDMI receiver you will want to look for a few things that you should consider essential before spending your hard earned cash. One of the most important things to consider are the number of inputs that your new HDMI receiver has. You will likely want a receiver that has at least two but preferably four HDMI inputs and two HDMI outputs. You will also want to make sure that the receiver has enough coaxial and component inputs as well.

Look to purchase a receiver of the highest quality that you can afford. Receivers are not the place that you want to "cheap out" and get an inferior product. If you purchase a low quality receiver you can reasonably expect that the audio and image quality of your home theater system will be compromised negatively. I would suggest that you look to spend at least in the middle hundreds, 0-0, on the lower end to get a good receiver. When you purchase a receiver also check to make sure that the model you select is up to date in terms of audio decoding. You would be better served getting a HDMI receiver that will handle audio decoding as opposed to purchasing a passthrough receiver that will put the audio decoding on your video player of choice.

Another thing to look for is upconversion and cross conversion which will allow you to cut out the bulk of the cables going in and out of your receiver to and from other components. This is more of an optional consideration but it may be well worth the extra money if you don't want to set up or go through a ton of wires when you are making any adjustments or setting up your home theater system.

In short don't skimp when purchasing your HDMI receiver. A good, high quality receiver hooked up to superb surround sound speakers will make you realize what you were missing when you were merely listening to the audio from your television. You won't regret spending some extra money for that real home theater experience when purchasing your receiver.

Tips For Buying HDMI Cables

There are many people who enjoy having the most state of the art home theatre system possible. They can go out and spend a bundle on the best television and the best speakers, but if they do not have the proper HDMI cables, the quality will not be what it should be. Since the cables that come with most home theatre systems are not always of the best quality, it is important to know the best tips for buying HDMI cables.

The most important thing to remember when shopping for HDMI cables is to shop around. Take a look at the specifications for each kind of cable. They vary greatly between different types and the differences can have a significant impact on the price. Read the packaging carefully and only get what is needed to avoid spending unnecessary money.

In general, it is a good idea to go with CL2 cables. These cables are installed inside the wall and are far less likely to catch on fire than other types of cables. This is great for someone who may want to sell their home in the future because these cables will not meet with any opposition from a home inspector.

Brand names might be necessary for some things, but when it comes to HDMI cables, do not be afraid to go with the generic brand. Look over the specifications and make sure that they are the same as those from the name brand cables. If they are, then the generic brand cables will do exactly the same job at a far lower price than the name brands.

When buying HDMI cables, it is important to look at all of the specification and make sure that someone is not paying for more features than they need. Shoppers should also be aware that the generic brand is just as good as the name brand, which can be far more expensive. With these tips for buying HDMI cables, it should be no problem to have the best video and audio possible for a home theatre system.

What You Should Know About an HDMI Splitter

An HDMI splitter is able to send multimedia audio and video signals to multiple display devices. It does this by allowing two, or more, different High Definition Multimedia Interface output displays to share a single input source.

These splitters support many different types of HDMI devices such as a DVD player, video game consoles, computers with High Definition output, and satellite receiver boxes. When this device is used the signal is sent over a single cable with zero to little signal loss. The single cable also reduces clutter and saves quite a bit of space.

The devices are offered in 2, 4, or 8 port configurations and can be cascaded to accommodate even larger configurations of HDMI devices to be joined in a type of network. They are also available in matrix formats of 2 X 2 and 4X4 which are different combinations of a switch and a splitter to allow for remote access and control through TCP/IP or IR.

Installation of this device is relatively easy as it requires no software or device drivers to run. Thus it is simply plug and play as the saying goes. Its compact design is also a plus as it requires very little shelf space to sit on and can even be perched on top of your television if you have an inclination and the space to put it there.

Another reason that this device is so popular is its low power consumption. Thus you can update your home theater set up without using to much more power. A definite advantage when you consider the high cost of utilities nowadays. This allows you the freedom to enjoy your favorite form of entertainment without the worry that your electricity bill is going to wipe out your bank account.

Another key function of a splitter is to amplify and buffer HDMI input signals in such a way as to create two identical output signals simultaneously. Thus uncompressed streams of digital output are transmitted through the use of these devices.

The many applications that this kind of technology has been used for are interesting. For example in business it is being used in digital signage, classrooms, conference rooms, control rooms, shopping malls, information broadcasting, remote monitoring, and training facilities.

Because of its versatility in usage the HDMI splitter has become a very popular piece of technology. In fact it has been said that it dominates all other technology of this type in the field of audio and video entertainment. Thus if you are considering upgrading your home entertainment system then consider purchasing a splitter as a starting point.

How To Connect Laptop to Flat Screen LCD HD Plasma TV Video Clips.

Explaining how to use your flat planel TV as a computer monitor. The video came out longer than I expected, but I tried to touch all subjects that had been asked in forums that I've read. Some editing glitches bc I had to shorten it up to fit the 10 minute time frame. Enjoy.... Also, I used a Samson C01u USB mic & SONAR 6 LE to record the audio for this video. Just letting people know in case you were wondering how well the mic works.
