DVB-C is a standard for digital cable television transmission.
Frequency - carrier frequency (80-1000 MHz)
Symbolrate - symbol rate also known as the baud rate, refers to the number of signal changes per second (1000-10000 Kbaud)
Modulation - method used to convert digital data into an analog signal that can be transmitted over the cable network. In DVB-C, the most commonly used modulation schemes are 64-QAM (Quadrature Amplitude Modulation)
FEC - forward error correction is a technique used to reduce errors in the transmission of digital data. In DVB-C, FEC is typically specified using a ratio of the number of redundant bits to the total number of transmitted bits
