DVB uses UPnP as defined by DLNA. Device discovery is using UPnP DCP and CDS advertisements. Overview is here: http://www.etsi.org/deliver/etsi_ts/102900_102999/102905/01.01.01_60/ts_102905v010101p.pdf

Unfortunately the DLNA specs are not available for free, so I can't provide any. *Very* terse info on discovery here: http://www.dlna.org/industry/why_dlna/key_components/device_discovery/
