13Digital TV Network API
14######################

16The Digital TV net device controls the mapping of data packages that are part
17of a transport stream to be mapped into a virtual network interface,
18visible through the standard Linux network protocol stack.
19
20Currently, two encapsulations are supported:
21
22-  `Multi Protocol Encapsulation (MPE) <http://en.wikipedia.org/wiki/Multiprotocol_Encapsulation>`__
23
24-  `Ultra Lightweight Encapsulation (ULE) <http://en.wikipedia.org/wiki/Unidirectional_Lightweight_Encapsulation>`__
25
26In order to create the Linux virtual network interfaces, an application
27needs to tell to the Kernel what are the PIDs and the encapsulation
28types that are present on the transport stream. This is done through
29``/dev/dvb/adapter?/net?`` device node. The data will be available via
30virtual ``dvb?_?`` network interfaces, and will be controlled/routed via
31the standard ip tools (like ip, route, netstat, ifconfig, etc).
32
33Data types and and ioctl definitions are defined via ``linux/dvb/net.h``
34header.
