Music Speech (M/S)
This is a two-state signal to provide
information on whether music or
speech is being broadcasted. The
signal would permit receivers to be
equipped with two separate volume
controls, one for music and one for
speech, so that the listener could
adjust the balance between them to
suit his individual listening habits.
Enhanced Other Network Information
(EON)
This feature can be used to update
the information stored in a receiver
about program services other than the
one received. Alternative frequencies,
the PS name, Traffic Program and
Traffic Announcement identification
as well as Program Type and Program
Item Number information can be
transmitted for each other service.
The relation to the corresponding
program is established by means of
the relevant Program Identification.
Linkage information, consisting of four
data elements, provides the means
by which several program services
may be treated by the receiver as a
single service during times a common
program is carried. Linkage information
also provides a mechanism to signal an
extended set of related services.
Clock Time (CT)
Time and date codes should use
Coordinated Universal Time (UTC)
and Modified Julian Day (MJD). If
MJD = 0 the receiver should not be
updated. The listener, however, will
not use this information directly and
the conversion to local time and date
will be made in the receiver‘s circuitry.
CT is used as time stamp by various
RDS applications and thus it must be
accurate.
