Introduction
The TF 7710 HSCI/TF 7720 HSCI digital receiver is fully com-
pliant with the international Digital Video Broadcasting (DVB)
standard, and can receive digital broadcasts. For its operation
you need an antenna, which must be installed appropriately.
NOTE
In general we equate a channel with a frequency. Unlike ana-
logue broadcasts, however, digital broadcasts are not all as-
signed to their own frequencies; instead, multiple television
broadcasts are transmitted through a single frequency. The fre-
quency in digital broadcasting is usually called transponder. To
reduce confusion in this manual, the word service is preferably
used than channel as a term to indicate one television or radio
broadcast.
