DVRs are electronic devices that are used to record television programming in digital format (unlike the now outdated VCRs, which could only record material in standard analog format). HD DVRs are digital video recorders that are capable of capturing and saving recorded programming in high definition digital format. This means when you go to watch your recorded shows, you will be able to enjoy the same crystal clear resolution that they were broadcast in. There are a number of different manufacturers that produce these state of the art devices. You can purchase one of these devices for yourself at an electronics store, or lease one through your satellite or cable TV provider.
The function of HD DVRs is to allow television viewers to record and store programming in the highest resolution possible. A DVR is hooked up to the rest of your satellite or cable TV system to pick up the programming that is received. In addition to being able to record programming, DVRs also allow users to pause, rewind, and fast forward programs as they are watching them. With a DVR with dual tuners, users can record two programs simultaneously and even watch a third program at the same time. In order to be able to record and view HD programming, of course, you will need to also have an HD television set. If not, your DVR will only record programs in standard digital format.
These digital video recorders come in multiple different variations. The primary difference between the various types of DVRs is the amount of memory space they come with. When it comes time to record data, you will have the option of doing so in high or standard definition format, the former of which uses up more memory space. In order to save space, you can choose to record programs in standard digital format instead. For example, some DVRs are capable of storing up to 200 hours of programming in standard digital format. If you choose the higher resolution, the same DVRs will only record about 50 hours of programming. Likewise, a DVR that can store more than 1,300 hours of programming in standard digital format can only store about 150 hours in high definition format.
Because they are digital, digital video recorders may not be compatible with all cable systems, or they may need a decoder in order to get programming. Satellite service, unlike cable service, is completely digital, so all satellite systems will be compatible. If you are thinking about getting one of these devices for your home entertainment system, you will want to consider whether the monthly fees that go with this service fit into your budget. A good place to get information about the prices of digital video recorders and the services is the Internet. Look at the websites of satellite and cable TV providers, as well as websites that have consumer information. You can also call your satellite or cable TV provider to find out how much it would cost to add DVR services to your plan. But it is always a good idea to compare various options when it comes to prices.
