Data compression/MPEG1/MPEG2:
To transmit the current television standard (625 lines repeated 50 times per second) results in a digital data volume of 216 MBit/s. This would require bandwidths that cannot be provided by either terrestrial or satellite sources. The volume of data is thus compressed by electronic means to reduce the volume. In Europe, the
