Performed Actions
Evaluation of the identification signal and automatic switching to mono, stereo, or bilingual. Preparing four
demodulator source channels according to Table 2–2.
Evaluation of NICAM-C-bits and automatic switching to mono, stereo, or bilingual. Preparing four
demodulator source channels according to Table 2–2.
In case of bad or no NICAM reception, the MSP switches automatically to FM/AM mono and switches
back to NICAM if possible. A hysteresis prevents periodical switching.
Automatic searching for stereo/bilingual-identification in case of mono transmission. Automatic and non-
audible changes between Dual-FM and FM-NICAM standards while listening to the basic FM-mono sound
carrier.
Example: If starting with B/G-FM-Stereo, there will be a periodical alternation to B/G-NICAM in the
absence of FM-Stereo/Bilingual or NICAM-identification. Once an identification is detected, the MSP
keeps the corresponding standard.
Evaluation of the pilot signal and automatic switching to mono or stereo. Preparing four demodulator
source channels according to Table 2–2. Detection of the SAP carrier.
In the absence of SAP, the MSP switches to BTSC-stereo if available. If SAP is detected, the MSP
switches automatically to SAP (see Table 2–2).
