tain Posted September 29, 2016 Posted September 29, 2016 Why do modern TVs with internal QAM tuners properly display channel data (ie, "4-1 WCBS" versus "74-76473 RANDOM LETTERS") while external stand-alone QAM tuners only display the other "74-76473 RANDOM LETTERS" data? TVs seem to have some additional feature. I've seen this phenomenon several times in different settings. The general environment is an unencrypted QAM signal for local TV broadcasts via FIOS TV or other provider.
