    Home Entertainment Technology

    This page will bring together information on Home Entertainment and Audio/Visual technologies, paying particular attention to those technologies that I have personally deployed. A few additional source of information on advanced home theater technologies are:

    Television Services

    The three primary choices for television services are Satellite, Cable, or an off the air signal. Most people that are interested in home entertainment choose either sattelite or cable since the selection of channels for off the air reception is more limited.

    If you have a digital TV receiver (including all HD TV receivers), you will find that there are additional sub-channels from over-the-air reception, providing some additional programming, without getting cable or Satellite, but there are still many channels that are available only through Cable or Satellite.

    Between satellite and cable, satellite is likely to be a little bit less expensive, often even when you pay the extra $5 or so to get local channels. The services provided are comparable, both in terms of selection of channels, programming packages, and the availability of pay per view movies and events. The two main satellite providers are DirecTV and Dish network which provide comparable channel lineups.

    If you have high speed internet form your cable company, however, they will often offer a discount to those with both cable and high speed Internet, and this could make the cable option less expensive.

    If you choose to go with satellite TV, by committing to one or two years of service, most companies offer specials that provide you with free equipment, often for up to four rooms, as well as low cost recievers with built in digital video recorders. Such offers are available for DIRECTV through RapidSatellite.com. For Dish Network, similar offers are available from VMCSatellite. After you complete the agreed upon term of service, the equipment is yours to keep. It makes little sense not to take advantage of such an offer, but be sure to read the full terms of any offer to make sure that you will meet the terms of the offer, as the offers have penalties for early termination of service. Also, don't get more receivers than you need just because they are free, since you need to activate all of the receivers you get, and DirecTV and other satellite providers charge a fee (usually $5) per month for each additional receiver activated.

    Choosing a Television

    When considering the purchase of a new television there are several thinks to be aware of. To start, the broadcast standards are changing, and in a couple of years, over the air stations will broadcast only digital signals. If you are buying a new television, you want to make sure that you get one that is digital. All of the HD sets available in the US are digital, but there are for the smaller televisions, there are still models that are analog and will require use of a separate converter in a couple of years. Note that many of the larger TV's available today are monitors only, which means that they are not really televisions, but must be connected to a cable box or separate tuner to bring in a picture, so you will want to be sure that you are getting what you expect. If you have cable and the right functionality in your cable box, then a monitor might be all that you need, but if you want to get off the air signals, you need a tuner, either built in to the television, or as a separate box that can be connected to a monitor.

    When considering the display technology, your main choices are CRT, Plasma, LCD, and projection varieties. For smaller TV's, CRT or LCD is probably the way to go. CRT will be less expensive, but takes up more space and uses more power. Larger LCD TV's (e.g. 40 inches or lager) will be the most expensive. Plasma tends to be cheaper than LCD for these large screens, but suffers from burn in (over a long period of use) and uses much more power. For very large TVs (e.g. 50 inches and larger), projection technologies (e.g. DLP) are economical and give a very good picture.

    About this site:

    This site is intended to bring together in one place, information and links that are useful to those adding technology to their homes. I am a new user of these technologies, and ask for help from anyone that can correct any information I might post, or who has additional links or resources to suggest.
