In-Depth Information
The important factor in relation to the NIT is that many receivers, i.e.
set-top boxes, may behave in a “peculiar” manner if the transmission pa-
rameters in the NIT do not match the actual transmission. If, e.g. the
transmit frequency given in the NIT does not correspond to the actual re-
ceived frequency, many receivers, without any indication of reasons, may
simply refuse to reproduce any picture or sound.
