Both Microsoft and Adobe have announced new video player software as online streaming becomes increasingly prevalent, reports CNET and PaidContent.

Microsoft's new player, dubbed Silverlight, was announced at the National Association of Broadcasters Show in Las Vegas. The announcement also came with the naming of partners, including Major League Baseball and Netflix, who have already shown interest in its use. The software will be able to display web video within a variety of web browsers on Windows PCs or Apple computers.

That in-browser display is meant to reclaim marketshare from Adobe's Flash format, which is used on YouTube and MySpace.

Adobe also announced their new Adobe Media Player at the NAB tradeshow. PaidContent reports that this new software will include the ability to go offline with an ad-supported model. It will use RSS delivery to automatically update subscribers with new videos which can then be put on the users' desktop. The Media Player will reportedly be the only one that can play back Flash-formatted clips.
