Forward Error Correction (FEC) in Digital Television Transmission

  • Ulrich Reimers
Part of the Signals and Communication Technology book series (SCT)


In MPEG source coding (see chapters 3 and 4) redundancy and irrelevance are eliminated from the digital signal. However, this means that the signal is more vulnerable to disturbances in the transmission path. If a digital television image which has not been source-coded is transmitted at a data rate of, for example, 270 Mbit/s and one bit has been alterated during transmission, only one pixel of the image will be affected in most cases. However, if an MPEG-coded image is transmitted, a bit error can result in at least one erroneous macroblock, if not in several.
