What is dvbInaIfDsChModulation?

The modulation scheme used on this downstream channel (default qpsk; in-band channels may also use qam16 through qam256). Higher-order QAM carries more bits per symbol but tolerates less noise, so operators pick it based on downstream plant signal quality.

Examples
