Types of HDTV Recorders

Having an HDTV can change the way you watch television forever. However, not everything has to change. For example, you can still keep on recording your favorite television shows and movies. You just need to get an HDTV recorder.

There are various types of HDTV recorder. One is the DVD recorder with built-in ATSC tuner. This type of tuner is the same one built into HDTVs, which means that your DVD recorder can receive digital over-the-air signals, including high definition broadcast signals, which, in turn, allows you to record them.

In spite of this, though, the signals will still be downscaled and recorded in a standard definition format, and not a high definition format, since they are stored on a regular DVD. This, in turn, means that you won't be able to watch them in their original HD format when you play them back, although the video quality can be almost the same if your DVD recorder has an upscaling feature.

Another type of HD recorder is the High Definition Digital Video Recorder or HD DVR. Just like the standard DVR, an HD DVR allows you to view and record your favorite shows, or even more. The only difference is that they are programmed to receive and store high definition broadcast signals, as well as analog ones. HD DVRs can be purchased from satellite and cable television companies, often as an upgrade or add-on to your subscription, but they can also be bought separately.

Currently, TiVo HD DVRs are the most popular choice, since they also allow you to pause, rewind or fast forward your favorite shows, or even show them in slow motion so you won't have to miss a single detail. TiVo also offers dual tuner functionality, which means you can record a show while watching another - something which is not found on the more expensive Sony HD DVRs. One good thing about Sony HD DVRs, though, like the DHG-HDD250 and the DHG-HDD500, is that they can store more hours - 30 or 60 hours, respectively - and offer an on-screen electronic program guide (EPG) at no additional charge.

Internal HDTV tuners or HDTV tuner cards, which are also called PC tuners or video capture cards, also have HDTV recorder capability. Like some HD DVRs, some allow you to pause live HD content as well. These functions, aside from their lower price, are why some prefer them over the external HD tuners or regular set-top-boxes. However, they have some disadvantages, too, such as the fact that they require you to have a computer and are more difficult to install.

Once installed, though, an HDTV tuner card can help you record your favorite shows on a disc without having to scale them down - if you have a Blu-Ray writer installed in your computer, that is. This is because you can get them to store them on a Blu-Ray disc instead of a regular DVD - either a BD-R disc for single use or a reusable BD-RE disc - which is capable of delivering content in full HD 1080p format. You can only play this disc on a Blu-Ray player or reader, though.

Now that you know about the HDTV recorders available, it is up to you to choose which HDTV recorder you want to get, depending on which one is most convenient for you or which one fits your budget. No matter which type you choose, though, just keep in mind that the HDTV recorder is there to help enhance your personal viewing experience and should not be used for profit in accordance with copyright laws.
