HDTV will be greater leap in quality home entertainment experience that even the transition from black and white on TV or Hi-Fi stereo, FM or AM. HDTV, as well as video and audio will also offer data services such as electronic program guides or information related to programs that control. Local television stations broadcast in HD will be able to pass a further high image quality, or more separate corners of equality with the images of today. HDTV will offer the opportunity to develop advanced services that meet consumer demand for flexibility and convenience.

HD will be presented in 16:9 format and allow resolutions up to 1940×1080, plus offer twice the amount of information image both vertically and horizontally. Will not work on regular analog TV sets do not support these interfaces required for HDTV signals. After February 17, 2009 analog TV channels will stop the local transport, everything else connected to the analogue TV will continue to work.

HDTV with time is very widespread, high-definition movies will be on the shelves, played on Blu-ray, HD DVD or both, depending on how the format war go. When you switch to HD, you need to connect the HD set-top boxes, Blu-ray and HD DVD to the TV using an HDMI (High-Definition Multimedia Interface) cable. Blu-ray and HD DVD is compatible with current DVD standard, so you can play the discs present a next-gen player, but the two competing formats are not compatible. It’s a little laugh, if you’re old enough to remember the beta-Max and VHS wars.

Technology
What are the problems faced by early adopters of this new technology and what warnings are still to be integrated, people buy HDTV unit now known as early adopters. Buy what is usually the last more, especially in Hi-Tech. Other consumers will be sold to technology. A large number of older television sets will soon become obsolete when the owners make plans for their replacement, as the new HDTV technology that existed at the time of mass conversion will be very attractive. You can bet that there will be a market for 'conversion material "to allow the use of" set analog "with the new HD Broadcast Technology. If I record off-air local broadcasts for the video will not be able to continue to do so after the February 17, 2009 not upgraded. To continue the registration of local television programs should connect to a TV analog to digital converter for the video recorder or buy a different TV which has digital TV tuner built in which will continue to record programs from local TV stations after February 17, 2009 . The advent of Tivo eventually make the question irrelevant video.

While the prices of HDTV sets are falling, the equivalent of many high-definition free technologies we have come to see, remains relatively expensive, such as recording and home media. HD DVD and Blu-ray war is another slowdown in the realization of high-definition technology into the mainstream. In fact, the distinction between major rivals HD, will be almost imperceptible unless you are viewing on screen 55+ in size.

Antenna
In cities across the country stations has already begun transmitting an HDTV signal, the credits with an antenna. To receive over-the-air HD digital signals, you need a digital receiver and antenna. To watch the local network affiliates, some customers may need to switch from satellite dish into an antenna. To receive HDTV through an antenna will need: an HDTV, HDTV, HDTV antenna. Depending on the location you may need an antenna rotor point the antenna in many transmission towers.

One of the main obstacles to be overcome by over-the-air HD broadcasts are via an antenna technology has won the misconceptions consumers long-held myths, and the lack of knowledge about the capabilities of antennas. The solution for the antenna / satellite conversion like this can have a long-term effect on the response from consumers seemingly obvious question on the material.

Note: The HDTV receivers that are built into high-definition televisions are many over-the-air using an antenna Tuners and can be used as an HD cable receiver.
Always a good idea to check with your local dealer on what the TV is a HDTV service is available in your area before buying. It would be a good idea to invite the local television stations and ask the chief engineer to learn the information channels.
