Co-axial cable:
Connection cable between LNB and satellite receiver,
used to transmit the signals received, and to supply

Data compression/MPEG1/MPEG2:
The volume of data involved in transmitting the current
television standard (625 lines, and a picture frequency of
50 Hz results in a figure of 216 MBit/s of digital data.
This would require bandwidths that can currently not
provided, whether by satellites nor by terrestrial systems.
For this reason, the total volume of data transmitted is
reduced by means of a compression algorithm. For
Europe, MPEG-2 has been accepted as the international
standard for data compression. MPEG-2 is an expanded
version of MPEG-1.
