Greetings TOM!   
      
      
    RW> RW>>> Not on an analog station.   
      
    RW> TW>> I am not talking abuut secondary Audio but Multiplexing of TV   
    RW> TW>> signals on a digital Tv Transmitter.   
      
    RW>> That's what I said.   
      
    RW> RW> TW>>> The more channels of course means lower broadcast quality.   
    RW> RW> TW>>> Here is a bit form the Internet:   
      
    RW> RW> TW>>> Trinity Broadcasting Network stations has five SDTV   
    RW> RW> TW>>> channels, the most of any large broadcaster in the country.   
      
    RW> RW>>> We have the same 5 Trinity channels in San Antonio...now what?   
      
    RW> TW>> IF they are multiplexing you can get more than 5 TV signals from   
    RW> TW>> those 5 transmitters.   
      
    RW>> Doubt it. That would be pushing the envelope too far and they'd be   
    RW>> xmitting out of their allocated band frequency. As a HAM or HAM   
    RW>> advocate, you should know that the very idea of xmitting on the edge   
    RW>> of a band will get you in trouble with the FCC.   
      
      
    TW> Well there are stations doing it. Both Ch 8 & 10 here trasnmit   
    TW> additional TV signals in addition to their Main Programing.   
      
   Well, you do know that they don't transmit that programming on the edge of   
   their allocated bandwidth, don't you?   
      
    TW> IT is Possible becasue the signal is Digital and they can use various   
    TW> compression teniques to make it possable and still stay withing the   
    TW> FCC band Width alocation. OF course Full hi Definition(1080) takes   
    TW> the full channel so as I mentioned previously the signals are of   
    TW> lower quality.   
      
   LOL! If 1080i is, in your opinion, low quality, that's a hoot. Most of   
   them use 720 and sometimes even 480 on a regular basis. Finding a 1080   
   transmission is about as rare as hen's teeth.   
      
      
       Have a day!
