DVB-C, as defined by ITU-T J.83 has 3 annexes. The differences between Annex A and Annex C is that Annex C uses a subset of the modulation types, and uses a different rolloff factor. A different rolloff means that the bandwidth required is slicely different, and may affect the saw filter configuration at the tuners. Also, some demods have different configurations, depending on using Annex A or Annex C. So, allow userspace to specify it, by changing the rolloff factor.

<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>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>

see the following documents:</para>

<para>ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial

|
|
<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>
