Selected TV Sound Standard
Performed Actions
B/G-FM, D/K-FM, M-Korea,
and M-Japan
Evaluation of the identification signal and automatic switching to mono, stereo, or bilingual. Preparing four
demodulator source channels according to Table 2
2.
B/G-NICAM, L-NICAM, I-NICAM,
D/K-NICAM
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.
B/G-FM, B/G-NICAM
or
D/K1-FM, D/K2-FM, D/K3-FM,
and D/K-NICAM
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.
BTSC-STEREO, FM Radio
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.
M-BTSC-SAP
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).
