2012-03-08 As mentioned at Ziggo begint met QAM256 ... 8 years ago
As mentioned at Ziggo begint met QAM256 - Digitale Kabeltelevisie (Dutch) my cable provider is switching to QAM256 modulation which allows for 8 bits per symbol, from QAM64 which allows for 6 bits. I noticed it today when checking the information for discovery channel. The signal strength is about 55% but the error rate is 0%, so reception is fine. This should give more services at some point in the future, but my best guess those will cost extra money too. Update 2012-03-13: It's interesting how Ziggo can do this in production (I call it "in production" when a number of running services is only available in QAM256) with tech news sites only picking this up days later. And still calling it a test. Although they probably don't use the extra bandwidth so they can switch back.
