Billed as “the world’s first camera-top wireless HD video encoder,” the Cube from Irvine, CA-based Teradek streams up to 1080p over Wi-Fi, Verizon 4G, and wired Ethernet.

The battery-powered H264 encoder sends video directly from a camera to a decoding device such as a laptop or iPad. The Cube is available in HD-SDI and HDMI models running in the $1500-2000 range, and is designed for those in the business of live streaming — or those looking for production solutions such as on-set video monitoring or eliminating the need for camera tethering.

To operate, the Cube slides into the camera’s hot shoe and goes live with a single button via Livestream.com. Gizmodo reports the process is “unhampered by firewalls, blocked ports, and other network roadblocks.”

Early adopters earn a month of Livestream.com premium membership (about a $350 value) with a Cube purchase.

Internet TV pioneer Hulu is reportedly in discussions to transform its business model. Since its 2008 launch, Hulu has been one of the leaders in free online television delivery and web-video ad dollars.

The Wall Street Journal reports that Hulu’s three owners (NBC Universal, News Corp. and Disney) are concerned that free Web versions of their TV shows are cutting into their traditional business, and the three are at odds regarding how much of their content should be offered for free.

News Corp.’s Fox Broadcasting and Disney’s ABC are considering pulling some of their free content from Hulu (and selling more content to Hulu competitors), while Hulu management is discussing the idea of retooling Hulu as an online cable operator that would use the Web to provide live TV channels and video-on-demand content to customers. If they opt to move forward with such a plan, some form of Hulu’s free service would likely remain and it is possible Hulu Plus could be folded into the new service.
