In many ways, digital satellite TV is similar to traditional television broadcasts in that its content is transmitted through the airwaves and captured by an antenna (in the case of traditional TV) or satellite dish (in the case of digital satellite TV). Also, the types of content that can be broadcast by both systems are analog and digital.
Unlike traditional television, however, digital satellite TV is able to deliver digital broadcasts at more practical prices because of its significant coverage advantage. This advantage is brought about by the fact that in the satellite broadcasting the content is positioned thousands of kilometers above the ground (unlike the radio transmission towers used in traditional television which are, at best, just hundreds of meters above the ground), which translates to a much wider “footprint” and economies of scale that is applied to its pricing consideration.
Digital satellite TV compresses and encrypts the digital signals of the information prior to broadcast. These broadcasts are transmitted from satellite ground stations to the satellites, which are, in turn, “blindly” transmitted by the satellite to all areas within its “footprint”. These compressed and encrypted signals are received by satellite dishes that are installed at the households and, depending on the authorizations given based on the subscriptions availed of, get decompressed, decrypted, and displayed by the digital satellite TV set-top boxes that are connected to the television sets.
Compared to an erstwhile entertainment favorite, Cable TV, digital satellite TV has the following advantages:
PracticalityDigital satellite TV's main advantage over Cable TV is that it costs less to maintain the service because there are only four points of failure; i.e., the ground station, the satellite, the satellite dish, and the television itself. In Cable TV, there are several kilometers of cable that need to be checked when a particular subscriber loses his service, aside from trouble at the cable TV headend, other distribution points, and the television set. This advantage allows digital satellite TV service providers to charge less for digital content than cable TV providers.
Wider CoverageAmong the three broadcast media (digital satellite TV, traditional television broadcast, and Cable TV), Cable TV has the smallest coverage reach. This means that the addressable market is also the smallest for Cable TV, which limits the number of subscribers it can provide service to. In contrast, digital satellite TV only has one requirement, i.e., the area it will serve has a direct line of sight to the satellite. All a subscriber needs to purchase is a satellite-band compatible satellite dish, a provider-issued set-top box and a subscription plan with the digital satellite TV provider to enjoy the service.
There are several digital satellite TV providers that a potential subscriber may avail of. Among these are VOOM, DirecTV and DISH Network. These providers offer service packages that include high-definition TV channels and information aside from the standard packages that cable TV companies provide. All these without hurting your pocket any more than it would if you continued with your Cable TV service.
Digital Satellite Tv Receiver
DirecTV and other satellite TV systems offer more options in daily television viewing. Satellite TV receiver is accompanied by all TV systems required for completed installation. Satellite TV receiver is manufactured by several reputed companies like Phillips etc. A satellite TV receiver has control hub for all the audio and video equipment which is pre-owned by any consumer. It is easily connected to any appliance with the existing cables.
In some cases in order to connect a satellite TV receiver the phone line may need to be split if there is any DSL connection in the house. The rear panel of a satellite TV receiver comes with all important card access, the receiver ID number, AC power input, phone jack, Dolby digital outputs, antenna input (if you wish to connect to an off satellite antenna or analog cable system), TV/VCR output, S-Video Output, and Component Video Output and the Sat In, which connects the coaxial cable from the satellite dish antenna. The instruction manual gives all the information you need for anyone installing it themselves.
The complete system of installing a Satellite TV along with a satellite TV receiver comes with user manual, power supply cord, phone cord, RF Coaxial cable, RCA type Audio/ Video connecting cable, S-Video connecting cable, Telephone Cord, Access card, and the Infrared Universal Remote control with 2 AA batteries. This all is accompanied by the Satellite direct TV dish.
Some times satellite TV receiver may get overheated. This may cause the decoder messages to disappear at times. It may also seem that the satellite TV receiver has gone dead. Since overheating is a main surge in satellite TV receiver it may be overcome by placing two capacitors on the power supply board. These capacitors should be replaced for reliability before the working of satellite TV receiver comes to a total halt.
Satellite TV receiver can be for analogue communication signals or digitally compressed signals. There is only one company that currently manufactures a satellite TV receiver that can process both analogue and digital signals. Analogue satellite TV receiver processes signals in analogue format. For an analogue satellite TV receiver one must need to remember the actual settings required to tune in all the channels and communication. Analogue satellite TV receiver can be stand alone unit. It is usually cheaper but can receive signals from only one satellite. An analogue satellite TV receiver has built in antenna controller which can steer a motorized dish from one satellite to another.
Main job on any satellite TV receiver is to maximize the strength of incoming signals from the satellite. This job is done equally well by an analogue satellite TV receiver or a digital satellite TV receiver. Multi-mode switches allow one satellite TV receiver to provide video to more than one house.
Satellite TV receiver comes with various features such as advanced program guide, parental controls, multi-satellite capabilities, universal remote, etc. Digital satellite TV receiver has digital audio output and can record up to seventy hours. They also have a built in DVR and season pass function, wish list function, etc.
May it be analogue satellite TV receiver or digital satellite TV receiver both work with the satellite TV set up to give the best quality of signals received from the satellite from various channels.
