The name of the subsystem is "media", and not "linux_tv". Also, as we plan to add other stuff there in the future, let's rename also the media uAPI book to media_uapi, to make it clearer. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

DVB Network API
|
|
###############
|
|
The DVB net device controls the mapping of data packages that are part
|
|
of a transport stream to be mapped into a virtual network interface,
|
|
visible through the standard Linux network protocol stack.
|
|
|
|
Currently, two encapsulations are supported:
|
|
|
|
- `Multi Protocol Encapsulation (MPE) <http://en.wikipedia.org/wiki/Multiprotocol_Encapsulation>`__
|
|
|
|
- `Ultra Lightweight Encapsulation (ULE) <http://en.wikipedia.org/wiki/Unidirectional_Lightweight_Encapsulation>`__
|
|
|
|
In order to create the Linux virtual network interfaces, an application
|
|
needs to tell to the Kernel what are the PIDs and the encapsulation
|
|
types that are present on the transport stream. This is done through
|
|
``/dev/dvb/adapter?/net?`` device node. The data will be available via
|
|
virtual ``dvb?_?`` network interfaces, and will be controlled/routed via
|
|
the standard ip tools (like ip, route, netstat, ifconfig, etc).
|
|
|
|
Data types and and ioctl definitions are defined via ``linux/dvb/net.h``
|
|
header.
