Cable Vs. Dtv

A dish is not required for cable television.

There are two primary options when it comes to viewing television beyond the basic broadcast networks: cable or satellite. Both are provided digitally, and give you access to more channels than the standard digital TV broadcasts. DTV can refer to this digital television standard or the DirectTV satellite provider, but here refers to dish television providers in general.

Similarities

Many features are provided by both satellite and cable, depending on the package you select. You can get high-definition television from both, as well as the local network broadcast affiliates. Pay-per-view broadcasting is universally provided, while certain companies from each type have on-demand services. Almost all companies provide the option of DVR in which you can record and play back shows whenever you want and skip through commercials. Premium channels such as HBO and Starz are also universally available as add-ons.

Availability

Satellite is available in more areas than cable due to its transmission through the airwaves to various satellites in space that are viewable from almost everywhere barring tremendously bad weather. In contrast, cable requires that actual wires be able to reach your home and communicate in a centralized location. Check through the various cable and satellite providers to see which is available to you before making serious comparisons of their features.

Digital and Analog

Digital involves the transmission of a series of ones and zeros that are then translated into the images and audio. Because they are clearly defined as ones and zeros, you will always receive exactly the image intended by the communicator on the other side. Analog, on the other hand, transmits an approximation of sound or images, and its quality can be affected by many factors over the course of communication, including wire types and signal reception. All satellite channels are digital, and most cable channels are as well, but there are still a few cable channels that transmit using analog means.

Equipment

Receivers are very similar for both services, but satellites do require a dish be installed somewhere on the roof or outer walls of your home. Some providers charge for this installation of either dishes or receivers, and some do not. Make sure you are aware of what services are included in your sign-up package.

Weather and Reception

Weather can affect satellite reception, whereas cable is completely unaffected by this factor. If you live in a generally stormy area, this is something to consider, but most rainstorms will not affect reception significantly. There are other factors on the provider's side that can affect your ability to receive service at all, but these are generally out of the control of the user.

View

If you choose satellite, a direct line to the southern sky is required from your home. While most households won't have a problem with this, some apartment buildings become trickier and will require manager permission. Heavily forested homes can also become a problem. Your installer will usually be responsible for these issues, but it is something to keep in mind when you make your selection.
