So what is DLNA? DLNA stands for DIGITAL LIVING NETWORK ALLIANCE. It is a consortium of manufacturers of consumer electronics, mobile phones, and computers. The goal is to create a set of solutions for personal computers, consumer devices, and mobile devices, including wireless and wired network interconnection, to fully realize the digital lifestyle of consumers.

– **Images:** PNG, GIF, TIF
– **Audio:** AAC, AC-3, ATRAC 3+, MP3, WMA9
