Recent BlackBerry 7.1 OS releases have included a new Wireless Media Server feature that we have covered before. It allows you to share pictures, music, and video from your BlackBerry to other media devices over Wi-Fi. We also know that RIM has confirmed that BlackBerry 10 devices will be DLNA certified. I have tried explaining the difference a few times to readers but I think RIM has done a great job of it in their knowledge base.
To boil it all down BlackBerry 7.1 devices make use of the uPNP standards and are not DLNA certified. For a device to be DLNA certified it needs to support both uPNP and DLNA though many of you have discovered that DLNA devices work just fine with the uPNP BlackBerry 7.1 media server. Still it will be nice when RIM adds DLNA support to BlackBerry 10 and the PlayBook. I am really hoping they add DLNA control along with streaming.

Got it working very quickly with Windows Media Player on Windows 7, except all my files show up in triplicate in Media player. Streaming works insanely well though!

It’s convenient to use Wi-Fi. And I think I’ve been dependent on it. It’s good to know that BlackBerry 7.1 OS allows us to share pictures, music, and video from your BlackBerry to other media devices over Wi-Fi.
