Now we should learn about some technical terms and standards so that we know how to build a home theater system. This should be an easy home improvement project, but can be a very expensive project.
High Definition TV, HDTV, the new broadcast standard format for digital TV signals is ATSC for the USA and DVB for Europe and most of the rest of the world. HDTV also supports surround sound audio 5.1-channel.
The USA is going to stop broadcasting analog signals on Feb. 17, 2009 in metropolitan areas, rural areas could still have analog signals. The rural local TV stations should be telling you if they are going to change to digital broadcasting.
For those of us in the United States with a newer analog TV, can still use our old TVs with the "TV Converter Box Coupon Program" which allows United States house holds to get upto two $40.00 coupons that can be used to help cover the cost of an eligible converter box. All new HDTVs should come with a HD tuner.
HDTV systems are describe by three parameters, frames or fields per second, the scanning system, and number of lines in the vertical display.
The progressive p scanning system draws an image per refresh frame. The interlaced i scanning system draws every other line then draws in the other lines on a second pass per frame.
A 1280 x 720 pixels TV with progressive scanning at 60 frames per second is called a 720p60 monitor. A 1920 x 1080 pixels TV with an interlaced scanning at 50 frames per second is called a 1080i50 monitor. Some of the newer HDTVs have a refresh rate of a 120 HZ or frames per second.
Selecting the terrific home theater receiver for your home theater is a exacting effort. The price tag varies from a few hundred dollars to many thousands of dollars as well as the quality. How do you choose the right one for your enjoyment. What can the receiver do and what do you need to build home theater.
Blu-ray has won the next generation DVD player battle. The Blu-ray DVD unit still has a high cost. It may take a year or more for the price of these units to come down.
What kind of speaker system do you want? A stereo system or a surround sound system, if surround sound system, do you want a 5.1, 6.1 or 71. system. How large of a theater room do you have? You need to match the size of the system to your room.
Also in our area the Telephone company is adding fiber optic cable so that will be another choice for a distribution system of either fiber,cable or satellite.
