If you’ve ever wondered how your gadgets talk amongst themselves to successfully play music from your PC through a media streamer, you’ll be interested in this interview with Dr Alan Messer, President of the UPnP Forum.
Universal Plug and Play (UPnP) is the standard by which IP networked gadgets advertise their services and intercommunicate. Formed in 1999, nearly all the big vendors are signed up with over 1000 members, the notable exception being Apple who tend to do their own thing. Think Intel, Samsung, Nokia, Philips.
The most common example of UPnP (AV spec) is DLNA-certification which governs media management, discovery and control and this effectively determines how music is streamed from one device to another. Set-top boxes know how to use different router ports based on UPnP techniques. Almost any consumer device attached to the network in the home will have some element of UPnP built-in.
(No, Andy, it’s not the ISA PnP but thanks for the trip down memory lane.)
