Move generic stuff into gen-errors.xml, and remove them from DVB API. While here, removes two bogus error codes that aren't supported or used on Linux: EINTERNAL and ENOSIGNAL. Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

<para>An ISDB-Tsb channel (1 or 3 segments) can be broadcasted alone or in a

set of connected ISDB-Tsb channels. In this set of channels every

channel can be received independently. The number of connected
|
|
ISDB-Tsb segment can vary, e.g. depending on the frequency spectrum
|
|
bandwidth available.</para>
|
|
|
|
<para>Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The
|
|
broadcaster has several possibilities to put those channels in the
|
|
air: Assuming a normal 13-segment ISDB-T spectrum he can align the 8
|
|
segments from position 1-8 to 5-13 or anything in between.</para>
|
|
|
|
<para>The underlying layer of segments are subchannels: each segment is
|
|
consisting of several subchannels with a predefined IDs. A sub-channel
|
|
is used to help the demodulator to synchronize on the channel.</para>
|
|
|
|
<para>An ISDB-T channel is always centered over all sub-channels. As for

|
the example above, in ISDB-Tsb it is no longer as simple as that.</para>

<para>Hierarchical reception in ISDB-T is achieved by enabling or disabling
|
|
layers in the decoding process. Setting all bits of

<constant>DTV_ISDBT_LAYER_ENABLED</constant> to '1' forces all layers (if applicable) to be
|

demodulated. This is the default.</para>

<para>If the channel is in the partial reception mode
|

(<constant>DTV_ISDBT_PARTIAL_RECEPTION</constant> = 1) the central segment can be decoded

independently of the other 12 segments. In that mode layer A has to

have a <constant>SEGMENT_COUNT</constant> of 1.</para>

<para>In ISDB-Tsb only layer A is used, it can be 1 or 3 in ISDB-Tsb

<para>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.</para>

<para>The information given here should help application writers to know how
|
|
to handle ISDB-T and ISDB-Tsb hardware using the Linux DVB-API.</para>
|

<para>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:</para>
|

<para>ARIB STD-B31 - "Transmission System for Digital Terrestrial
|
|
Television Broadcasting" and</para>

|
<para>ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial
|
|
Television Broadcasting".</para>
|
|
<para>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.</para>
