It was recently discovered that RIM has joined DLNA (Digital Living Network Alliance) which is an open standard for content and media sharing between electronic devices. This includes sharing content from a BlackBerry to a TV. As a finalist in the BBM Challenge Council contest, DLNA support for the PlayBook was something I advocated. Thus, I was pleasantly surprised to see that DLNA will be supported on OS 7.1 very soon.
RIM recently announced its upcoming BlackBerry Wireless Media Server. In the latest leaks of OS 7.1, users can already use this feature to share content (e.g. pictures, music and videos) from their BlackBerry to any device that supports DLNA (e.g. a TV). This sharing is done wirelessly through Wi-Fi. Click on the video above to see a demo of someone viewing the contents of their BlackBerry on their TV using the BlackBerry Wireless Media Server.
