What Is Fec In Satellite Receiver

Antenna is the most critical part in the communication link here.

What is fec in satellite receiver. The acronym stands for digital. In addition satellite receiver will have control circuits to change the position of the satellite dish antenna. Fec processing in a receiver may be applied to a digital bit stream or in the demodulation of a digitally modulated carrier. Digital cable which also has improved picture quality and extended channel selection has proven to be the fiercest competitor to satellite providers.

Fec is one of the significant parameters of the satellite receiver. Modulation and fec rate and fec coding method. Forward error correction fec is a method of obtaining error control in data transmission in which the source transmitter sends redundant data and the destination. The signal of the satellite on earth very in strength.

For the latter fec is an integral part of the initial analog to digital conversion in the receiver. The first fec code called a hamming code was introduced in the early 1950s. As the process rate of the cpu of digital receivers improves today s digital satellite receiver can measure the fec parameter automatically thus users don t have to type in the parameter any more. However they are perfectly standard if we take into account the new norm the so called dvb s2.

In some early digital receivers the fec parameter has to be typed in by users. If this is a motorised polar mount system that has already been installed and aligned correctly setting the satellite selection on the receiver to 122 will make the motor turn the antenna to the correct satellite. Don t worry about 0 1 deg on the display. Minimum threshold eb no ber 10e 8 add an operating margin to this for clear sky set up depending on c or ku band and rain area.

Fec provides the receiver with the ability to correct errors without a reverse channel to request the retransmission of data. These receiver features are just added bonuses to the technology of satellite tv. This sounds rather limiting. I m looking at buying a fta digital receiver.

The fec corrected data is stored in the ram from where both video and audio portions are separated.
