DreamGEAR MSK 33 manual Hierarchy, Dvb-T

DVB-T

Hierarchy

Meaning: Two carriers streams are simultaneously transmitted and the transport stream with the higher priority is QPSK modulated.

There are four hierarchy steps (0, 1, 2 and 4).

Hierarchy = 0 menus, that the signal is not hierarchy modulated.

Hierarchy = 1 means, that the signal is hierarchically modulated. Two transport streams are simultaneously transmitted, one has higher priority in QPSK.

Hierarchy = 2 menus, that the signal is hierarchically modulated. The modulation is compared to the QAM modulation is one step securer.

Hierarchy = 4 means, that the signal is hierarchically modulated. the QPSK modulation is securer that the QAM modulation by two steps.
