QAM is the correct terminology for the DTT coding, Cofdm is another level on top. It just represents how many levels in the carrier amplitude are used to carry data. The Cofdm bit is the x-thousand carriers with very long bit periods, and a few other tricks. As for which ones are 64QAM, I believe all are 16QAM except the ITV Mux, but am not 100% sure. ITV Mux (Mux 2) and SDN (Mux A). In other words, ITV-1,2, C4, C5 QVC, Bid-up Tv, and BBC Radios 1-4 are all at 64QAM, and therefore more susceptible to interference |
