[media] DocBook/dvbproperty.xml: Document the terrestrial delivery systems
Instead of repeating duplicate parameters to each delivery system, just add a section for each specific delivery system, showing what's applicable to each case. This helps userspace app developers to know what DVB parameters are applicable to each delivery system. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
