What Are The Satellite Receivers

Satellite receivers are electronic devices that allow satellite television tuner, receiving the signal from the satellite dish outside, the decoded and displayed on the TV. There are satellite receivers external, internal and PC, and have many features such as high definition, ability to decrypt, TDT, upgradeable firmware, media player, hard disk, Ethernet, card reader, USB, Time Shift, parental control or games.

Types of satellite receivers

Recipients receive satellite television signals from the satellite dish outside, the decoded and displayed on the TV, though there are various formats:

External satellite receivers, are external devices that connect to the TV and the signal source. Domestic satellite receivers, are integrated into the TV. Satellite Receivers PC tuner cards are PCMCIA or USB interface to connect to a personal computer. The satellite TV

Satellite television is a television system that transmits television signals via a communications satellite, so that the signal can be tuned from other parts of the Earth by satellite dishes and satellite receivers.

In satellite television involves three elements:

Issuer: satellite television began in the transmitting antenna of the transmitter station. These satellite dishes are directed toward a specific satellite and are very large, between 9 and 12 m in diameter, to transmit the signal with the most power possible. Satellite: get the signal from the transmitter station and relayed to Earth on a different frequency to avoid interference with the received signal. Receiver: from the satellite signal is collected by the satellite dish reception, usually between 60 and 80 cm in diameter and equipped with an LNB (Low Noise Block, Low Noise Block) which amplifies, filters and converts the signal frequency . Then sends the signal to the satellite receiver through coaxial cable, where it is decoded into the desired shape (TV out, audio or data). Features

Here are some important features to consider in satellite receivers:

Analog / digital satellite TV is broadcast in analog and digital. High Definition: Many channels broadcast in high definition (HD, High Definition). Channels: some recipients can decrypt the satellite signal, which allows to tune premium channels. DTV: Some models allow you to tune DTT channels. Firmware Update: It is desirable that the firmware is upgradeable to add future functionality. Controls: Satellite receivers typically used by remote control and menus, the TV acting as OSD, although some have buttons and LCD display. Connectors: he must have a common connectors such as DVI, HDMI, S-Video and SCART. Additional Features: Many models have features like media player, hard disk, Ethernet, card reader, USB connector, delayed reproduction (Time Shift), parental control, block channels or games.
