+1 from my side. As I mentioned some time ago, DVB has adopted DLNA's device discovery which is based on UPnP. So there might be a point sending out a liaison to DLNA asking them for information on their device discovery Java API.

But there are also quite some Open Source implementations that are compatible with DLNA: http://elinux.org/DLNA_Open_Source_Projects

Assuming we had that in place, one could very easily implement and use the MHP 1.3 Java APIs for service discovery. The most prominent might be these two:

getServiceProviderRecords
        Element[] getServiceProviderRecords()
                Provides access to the SD&S Service Provider records 
        Returns:
                an array of SD&S Service Provider Records

getServiceOfferingRecords
        Element[] getServiceOfferingRecords(java.lang.String domainName)
               Provides access to the SD&S Service Offering records
                for a particular Service Provider
        Parameters:
               domainName - Domain name of the service provider for
                which offerings are requested
        Returns:
               an array of SD&S Service Offering Records, including
                BCG records

Get all service providers, the see what they offer.
