SoC 2010/DLNA UPnP Server Client Modules

This project is part of Google Summer of Code 2010. Student: Austin Burrow Mentor: Konstantin Pavlov

DLNA UPnP Server/Client Modules

Abstract

The Digital Living Network Alliance (DLNA) offers a standard that many manufacturers use as a way to keep compatibility across different products that use UPnP. As of 2008, over 5,500 different devices and over 200 million sold products use the DLNA standard. This project will improve the current UPnP model, and apply the DLNA standard as Client/Server modules.

What I'm Working On

UPnP SD Client

	Description	Status
Item Duplication Bug	The current implementation of services_discovery_AddItem does not allow items to be inserted anywhere into any sub-node. The current fix must rebuild the whole UPnP Server directory on every directory update. This is not an optimal solution because it causes a "refresh" to be seen in the playlist. This also causes the users selection to disappear, and the user is required to traverse through the directory tree to find the item again.	On Hold (Semi-fixed)

UPnP DLNA Server

	Description	Status
libdlna Implementation	Implement the libdlna library, get simple test cases working.	Active
Special Cases	Implement special cases for certain devices such as the Playstation 3 and XBOX 360. This will require the use of Wireshark, or some other packet sniffer to be able to sort out what's going on between the consoles and a fully supported DLNA server. This is a requirement because I am unable to get my hands on a free specification of the DLNA standard.	Not Started
