There are two types of broadcast services:
• MPS = Main Program Service
• SPS = Secondary Program Service
IBOC Station List Menu
Both services differ to the effect that the signal previously broadcast analog in the MPS is
now used in digital form.
The decoder delays digital reception for several seconds until it is synchronous again with
the analog signal previously heard.
SPS offers additional radio stations that are only broadcast in digital form. Using the multi-
cast method, it is possible to accommodate up to seven digital stations in the submenu
of the SPS main station. Normally, however, a maximum of 3 sub-menu are offered in the
SPS.
Sub-menu of the IBOC main station
The system automatically switches over to analog FM reception if the digital signal is no
longer available.
HD radio is also available in the AM frequency range. In this case, the digital signals are
transmitted on directly adjacent frequencies of the analog station. Multicast is not sup-
ported on AM. The content of the digitally broadcast station is the same as that of the
analog station.
HD radio plays AM radio stations in near-FM quality and FM radio stations in near-CD
quality.
