Wide-screen movies will show letterboxing at the top and bottom, rather than the left and right sides. Just briefly, this is what you’d see with the two most common wide-screen movie aspect ratios, 1.85: 1 and 2.35:1, shown in Figures 5-3 and 5-4.

Again, whether you do that or not entirely depends on Exploring Digital TV and Satellite Radio how you value image quality.Figure 5-4:A 2.35:1movie willshow largerblack orgray bars atthe top andbottom.400 Shopping for an HDTV That’s resolution, interlacing, and aspect ratios in a nutshell. There are many more considerations when buying an HDTV. Mostly, though, take along some content (DVDs or Blu-ray movies) with you when buying an HDTV or at least insist on watching some content that you tend to view often. Then choose the TV based on what you see on the screen.Shopping for an HDTV Now that you have an understanding of several key technical terms, let’s go shopping! Consider the following items when shopping for an HDTV: ✦ Budget: How much money are you willing to spend? Your budget deter- mines what feature set you can afford and also affects the ultimate screen size of the HDTV you purchase. ✦ Physical size: Have a huge living room and a small budget? Maybe a large format, DLP rear projection TV would work. On the other hand, if you have tight space constraints, perhaps because you have a particular piece of furniture that will house the HDTV, then that will dictate the maximum size of the unit. ✦ Content Source: What’s the source of the HD content? If you want to use an over-the-air antenna exclusively, you’ll need an HDTV with a built-in tuner or you’ll have to make sure that an external tuner is part of the package. If you plan on watching exclusively through cable, then you may not need a built-in tuner. ✦ Connections: Finally, if all you want to connect is a cable or satellite box, you may not need many inputs. Similarly, if you’re connecting multiple devices through an A/V receiver, one input on the HDTV will suffice. But if you want to have many devices connected directly to the HDTV, then you want to have multiple inputs — as many as you have devices to connect. Prices of HDTVs have dropped considerably in the past several years, and it’s not uncommon to find a 50-inch LCD for around $1,000 and a 50-inch plasma at nearly the same price — and those are the prices for 1080p. Above about 55 inches, prices increase much more rapidly, due to manufacturing constraints. Again, determine your budget and space constraints before going shopping. Understanding Content Sources 401 A word about HDMI I’m assuming your entire setup is fairly current. source to the HDTV. It’s far more convenient Whether your cable company is supplying you than component video cables with separate with a cable box or you’re using a home theater digital audio cables, for example. Plus, HDMI A/V receiver, the best way to connect your HDTV can carry all the newer high-definition audio today is HDMI (high-definition multimedia inter- standards, such as Dolby TrueHD and DTS-HD face). HDMI carries both audio and video signals, Master Audio. so you only need one cable connecting a single As I noted earlier, make sure to watch some content on the HDTVs you’re seriously considering buying. Even good quality HDTVs may handle color, brightness, and contrast a little differently, so personal preference often has a strong impact on what you buy. Note also that most HDTVs in show- rooms typically have their controls set to be very bright, with very saturated colors, so that the images “pop” on the showroom floor. One final word about buying: you should also make sure to buy your HDTV from a store with a solid return and exchange policy, in case the unit you buy simply won’t work in your viewing environment.

The three primary sources of HDTV programming are over- the-air (OTA), cable TV, and satellite TV. A fourth source, streaming video f ...
