You must be wondering what does DLNA stand for? DLNA stands for Digital Living Network Alliance. DLNA is actually a non-profit trade organization started in 2003 and it defines certain standards which devices must follow while they share media. DLNA will act as a bridge between various devices, and will help in streaming media between device, like steaming music from your smartphone to be played on stereo player. Does it not sound like some home cloud?


A pre-requisite for this technology to work is the presence of a network, either wired or wireless. On what devices will you find DLNA? Well, about 440 million devices have them already, which include PS3, Windows PCs, home media servers, Android smart-phones, Blu-Ray disc players, tablets, flat-screen TVs, camcorders, routers and so on.

How does DLNA work? It uses the Universal Plug and Play (UPnP) to communicate. The three classes of DLNA devices are as follows:

  1. Home Network Devices. e.g. TVs, tablets. Consoles.
  2. Mobile Handheld devices. e.g. smart-phones, media tablets.
  3. Home Infrastructure Devices. e.g. hubs, routers.

Recently, a new standard called DLNA Premium video (DLNAPV) has been added so that it becomes easier to share copy-protected content, and it will act as a single device will act as a hub for all the other devices. At present, big shots in the tech field like HTC, Samsung, Microsoft, HP, Motorola, Intel, Panasonic, and LG have started making products which are DLNA supported. But, the leader, Apple, have not joined the group as of now.

What is the closest competitor to DLNA? Well, it is AirPlay. And you must have already guessed, it is only for Apple related products.
