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