These files are part of the dvb-core implementation, which builds
a driver framework usable by various hardware platforms. The
Linux DVB API document does not specify the details of the dvb-core
implementation, it deals mostly with the API visible to userspace
programs. There's an out-of-date description of the "kernel demux API",
though, which specifies part of the interaction between dvb-core and
demux hardware drivers.

Please note: We restructured the driver source as part of the effort
to get it included in linux-2.6. The result can be found in our CVS
module "dvb-kernel" (see http://linuxtv.org/cvs/), and in the current
linux-2.6-test kernel source.

Because of some shortcomings of the current API we currently are
working on the next API version, which is in CVS module "dvb-kernel-v4".
You can search the mailing list for more information, discussion started
around march.


Best regards,
Johannes
