To write virtual interfaces that format and send data to a broadcast encoder or other output systems, you can use the structures discussed in this section. These structures describe specific output systems and drivers and the data packets that virtual interfaces send to their systems. The following table lists and describes these structures.
| Structure | Description |
|---|---|
| MSBDN_BRIDGE_CALLBACKS | Contains information about pointers to callback functions exported by the MMR |
| MSBDN_OUTPUT_SUBSYSTEM | Contains information representing a specific output system |
| MSBDN_OUTPUT_VALUE | Contains information about a configuration value |
| PACKET_BUFFER | Contains information about a packet of data that a virtual interface transmits |
