Besides video and audio transmission, DVB features data transmission of all kind as a universal medium. The powerful error correction, the guaranteed data rate and the small channel bandwidth make a DVB solution more interesting than e.g. WLAN or other link systems.

Ethernet Transmission over DVB

• Transparent ethernet connection - no routing. To the network, the link looks like a wire

• Connected to a DVB-T modulator, the bridge provides netto data rates up to 30 mbit/s

• Stable Connection - significantly better than via WLAN

• Possibility of working with power amplifiers due to the separated input / output paths

• Based on an embedded Linux system: Linux development at request possible

• Optionally: Multiplexing with video and audio streams

Modulation Types

The bridge only being an interface between ethernet and SPI bus makes it possible to choose every modulation type that modulators and tuners are available for.
There is a completely separate link for each of both directions built up. That makes an asymmetrical operating feasible; for example a modulation configuration with greater transmission power in direction of the greater data volume with a stronger error correction on the return channel.
In addition to that, you can equip the bridge with ASI-in and ASI-out to multiplex an ethernet connection on an existing ASI-link.

Application Possibilities

• Data links between different locations

• Remote control of other DVB components

• Mobile data connections under difficult circumstances (multipath propagation)

• Application on frequencies that are inaccessable by another way (with corresponding up- and down-converters)

• Surveillance cameras with return channel, for example with rotating swivel base or announcement loudspeaker

• Bridging of ethernet data over ASI
