DVB-T2 delivery system
|

DVB-T2 support is currently in the early stages of development, so
|
|
expect that this section maygrow and become more detailed with time.

ISDB-T delivery system
|
|
======================
|
|
|
|
This ISDB-T/ISDB-Tsb API extension should reflect all information needed
|
|
to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible that some
|
|
very sophisticated devices won't need certain parameters to tune.
|
|
|
|
The information given here should help application writers to know how
|
|
to handle ISDB-T and ISDB-Tsb hardware using the Linux Digital TV API.
|
|
|
|
The details given here about ISDB-T and ISDB-Tsb are just enough to
|
|
basically show the dependencies between the needed parameter values, but
|
|
surely some information is left out. For more detailed information see
|
|
the following documents:
|
|
|
|
ARIB STD-B31 - "Transmission System for Digital Terrestrial Television
|
|
Broadcasting" and
|
|
|
|
ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television
|
|
Broadcasting".
|
|
|
|
In order to understand the ISDB specific parameters, one has to have
|
|
some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has
|
|
to be known to the reader that an ISDB-T channel consists of 13
|
|
segments, that it can have up to 3 layer sharing those segments, and
|
|
things like that.
|
|
|
