False NICAM detection...

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hello.

I found problem with false NICAM detection on one TV channel in my country. (TV-Prima on 
Czech Republic - Prague) Problem is confirmed by another users in this locality.

On another TV channel is detection OK. See:

Sep 22 17:36:43 localhost kernel: msp3400: setmode: 3
Sep 22 17:36:43 localhost kernel: msp3400: FM setstereo: 1
Sep 22 17:36:43 localhost kernel: msp34xx: setvolume: mute=off 65535:65535  v=0x73 b=0x00
Sep 22 17:36:43 localhost kernel: msp3400: main sound carrier: 6.501 MHz
Sep 22 17:36:43 localhost kernel: msp3400: FM-stereo carrier : 6.259 MHz

It is correect valuef for PAL-DK1 system used in my country.

But when I switch to TV-prima channel, is silent! This channel don't use stereo, it is only mono 
sound used. But autodetection of second carrier frequency false detect NICAM! (IMHO it is not 
second carrier frequency, it is end of bandwidth for PAL videosignal...) On end this message is 
part of log about this false detection.

If I can hear any sound on this channel, I must change volume on MSP chip.. and only after this I 
can hear any sound. :-( It is not good...

Is fix for this problem? Thanks.

Lukas.
