What Is Fec In Satellite Receiver

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

What is fec in satellite receiver. Digital cable which also has improved picture quality and extended channel selection has proven to be the fiercest competitor to satellite providers. 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. I was interested in the manhattan digi plaza but the specs in what satellite seemed to say the fec was fixed rather than selectable. In addition satellite receiver will have control circuits to change the position of the satellite dish antenna.

In some early digital receivers the fec parameter has to be typed in by users. Don t worry about 0 1 deg on the display. This sounds rather limiting. 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.

The acronym stands for digital. 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. With its movie quality picture and sound satellite tv is becoming a popular investment for consumers. Fec processing in a receiver may be applied to a digital bit stream or in the demodulation of a digitally modulated carrier.

Modulation and fec rate and fec coding method. For the latter fec is an integral part of the initial analog to digital conversion in the receiver. These receiver features are just added bonuses to the technology of satellite tv. The first fec code called a hamming code was introduced in the early 1950s.

3 4 and the information for azimuth and elevation as well. I m looking at buying a fta digital receiver. Fec provides the receiver with the ability to correct errors without a reverse channel to request the retransmission of data. The fec corrected data is stored in the ram from where both video and audio portions are separated.

However they are perfectly standard if we take into account the new norm the so called dvb s2.
