Google buys Internet video security firm Widevine

(AP) -- Google has agreed to buy a company whose software is used to protect Internet video from piracy and make it play more smoothly.

The Seattle-based company, Widevine Technologies Inc., makes so-called "digital rights management" software that's used to secure video content as it makes its way to a variety of consumer devices, such as Internet-connected TVs, personal computers and cell phones. Its software is also used to help make sure the content is delivered seamlessly, known in industry jargon as "optimization."

The purchase price wasn't disclosed.

Google Inc. which is based in Mountain View, owns the video-sharing site YouTube.
