Sony has updated the interface of their BRAVIA smart TVs to support social networking and high-definition YouTube videos. The new BRAVIA firmware has support for Facebook galleries, messages, status updates, and links. There is a Twitter ticket that scrolls updates from your followers. YouTube has been on BRAVIA smart TVs, but the update now has HD support.
Sony has also released a Remote Keyboard Lite application for non-Sony laptops and it allows them to enter URLs in the Opera-based browser. You can search for streaming content and navigate through menus. You will need a Windows 7 computer though. The firmware update should be pushed out automatically to sets as long as it is connected to the Internet.
