Investors are betting big on video streaming provider Move Networks. The Utah-based company just announced that it raised $46 million in a C round of venture financing. The round was led by Benchmark Capital, and also included Cisco, Comcast Interactive Media, Televisa, Steamboat Ventures and Hummer Winblad Venture Partners. That brings the total raised since December, 2006 to $91.3 million. (Competitor Brightcove has raised $86.2 million and Maven Networks was bought by Yahoo for $160 million in February).

When it comes to streaming HD video on the Web, Move Networks is becoming one of the preferred video streaming partners for many major media sites, including ABC.com, Discovery.com, ESPN.com,and Fox.com. According to the company, it collectively streams videos to 6.5 million people a month, who average 50 minutes of viewing time per session. But Move requires that viewers install its own proprietary video player as a plug-in to their browsers. So in a way it competes with Flash, which is getting better all the time. (Brightcove is taking a different approach by experimenting with BitTorrent and other technologies to create high-quality video experiences through a Flash player). High-definition streams still tend to run into network bottlenecks and slow connection speeds at people’s homes. Whoever can solve or bypass these problems will become adopted by more video sites as the demand for HD video rises.

Yahoo has acquired video publishing platform Maven Networks for $160 million. We were the first to report the deal the day the papers were signed, on January 31. The next day, Microsoft announced its bombshell offer for Yahoo, which probably delayed the announcement of this smaller acquisition. Everyone at Yahoo has been a little bit preoccupied.

Yahoo will use Maven’s technology to host video for media partners and incorporate Maven’s video-ad insertion technology into its overall advertising platform.

[Update 2/12/08: The deal has been confirmed. The price was $160 million.]

We’ve gotten word that Yahoo will make an acquisition announcement of a video startup today or tomorrow. At first we thought the target might be Metacafe, which was almost acquired by Yahoo just following the Google/YouTube deal in 2006. Shortly after, it made a small acquisition in Jumpcut, a Web-based video editor. But It’s not a video aggregator, we’ve heard, but a platform company. And the price is north of $100 million.

The price point limits the number of candidates. Brightcove is our top guess. If it is Brightcove, the price would have to be well north of $100 million, given that investors have poured $86 million into the company so far. More as this develops.

For an excellent overview of the online video space and its participants, see this post written by Brightcove CEO Jeremy Allaire and SVP Marketing Adam Berrey.

Update: It is not Brightcove. It is Maven Networks, another Boston-based video startup, three independent sources confirm. And the price is believed to be $150 million. Maven is a video-hosting platform for media sites, including Fox News, CBS Sports, CNet, and Scripps Networks. But Yahoo would probably want it more for its video-ad network, targeting, and insertion technologies. Maven has raised $30 million to date from investors include Accel, General Catalyst, and Prism Ventures.
