In the interest of feeding my media-hungry PC, I checked out the beta version of a new online video search tool today. Blinkx launched its free service on Tuesday, and you can check out its site at blinkx.tv. Behind the thickly worded About Us section is a fairly clever concept: finding your search terms in video clips by using speech-recognition software. The site looks a little rough at the moment, but it did what it claimed to, popping up video clips from sources such as CSPAN and ESPN. It'll also kick up a quick RSS feed of video sources for, say, Supreme Court nomination, or whatever keywords you want.
