[QUOTE="BGonaSTICK, post: 78064, member: 176912"] No, actually it's the FEC (Forward Error Correction). From SATCODX (which saved my typing it... :) ):- [b][color=black]Only applicable for digital transmissions. The FEC (Forward Error Correction) indicates how many Bytes are used for the actual signal, and how many for correction of errors. A FEC of 1/2 means that 1 Byte out of 2 is used for error correction, while a ratio of 7/8 means 7 Bytes are used for the actual signal, and only one for error correction. A FEC of 1/2 gives as perfect as possible reception, since every Byte containing actual signal is controlled by another Byte checking it. When a provider chooses a FEC of 7/8 it means he is not wasting any bandwidth at the cost of delivering a signal. The lower amount of error correction means that more sophisticated equipment at the receiving end (for example a more stable and sensitive LNB, or higher reserves with the dish) are needed compared to the same transmission using a FEC of 1/2.[/color][/b] [/QUOTE]
