HDTV CableCard

Look thorough the specifications list of many of the current crop of HDTVs and you will see the term CableCard listed on many of them, but what is HDTV CableCard?

Quite simply, it's a very elegant method of receiving HDTV from a cable provider.
Instead of supplying you with a set-top box to receive and decode its HDTV
transmission, the cable supplier gives you an HDTV CableCard which simply slots
into your TV. The card decodes the channels that your subscription allows your
receiver or integrated HDTV does the rest.

The advantage is that an HDTV CableCard takes up much less room than a set-top
box, doesn't need its own power supply, and reduces the number of cables you
need for cable HDTV. Another advantage is that if you move house and have to
switch providers, you don't need to learn how to use a brand new set-top box. You
just relinquish your existing card and get a new one from your new provider,
everything else stays the same.

Perhaps the biggest advantage of HDTV CableCard is in the picture quality. Cable
companies are not known for the high quality of the components they put into set-
top boxes. Most consumers can't tell the difference between a decent picture and a
very good one. So cable companies tend to go for features rather than quality. With
CableCard your equipment - the HDTV tuner or integrated HDTV does the scaling
and display, so you choose how good the image quality is. If it matters to you, you
can buy a good tuner or integrated TV and benefit from better scaling and display.

The disadvantage of HDTv CableCard is that it is currently one-way, so cable
services which requ00000892ire interaction, such as pay-per-view, on-demand services,
sports season tickets and program guides don't work. For those you'll still need a
set-top box.

A two-way version of CableCard is currently in development.

HDTV Tuners

HDTV tuners are specially planned devices which receive and output HDTV signals. The HDTV (high definition television) is the latest addition in DTV. These transmit programs in a widescreen format with high resolution pictures and surround sounds. Thus, they provide ambience and feel of theaters in homes.

The HDTV tuners are also known as a decoders, receivers, and set-top boxes. A HDTV tuner will receive signal in the form of ATSC formats. The received signals are decoded in HDTV signal before displaying it on your television screen. The picture quality of HDTV will range from 720p to 1080i with a ratio of 16:9. Generally, the HDTV tuners will receive all the HDTV signals including cable, satellite, OTA (over-the-air) broadcasts, and digital- VHS recordings.

Commonly, the HDTV tuners can be availed as an external box or come integrated with HDTV sets or HDTV receivers. The external HDTV tuners are usually connected between the antenna and the television. The television sets or receivers encompassed with HDTV tuners will not require external HDTV tuners to receive standard cable channels. For analog televisions and digital televisions without inbuilt HDTV tuners, the external HDTV tuner is the ideal way to enjoy the benefits of HDTV signals.

HDTV tuners are available in different price levels. On an average, the cost of the HDTV tuner will range from $100 to $400. The price will fluctuate from one brand to another.

Sharp, Panasonic, Mitsubishi, Thomson, and Samsung are some of the leading brands.

HDTV tuners can be availed from local dealers or online stores. An online store is the best source to avail better options in HDTV tuners. crutchfield.com, store.snapstream00000890.com, and digitalconnection.com are some of the leading online stores to shop for HDTV tuners.

The HDTV tuners with hard drives are capable of recording standard digital TV and HDTV programs. With advance features, an HDTV tuner will give you the ambience of a theater at home.
