The Raspberry Pi is an inexpensive little computer-on-a-board with a low-power processor, an Ethernet port, and HDMI output. If you want a video input, y0u can buy an optional camera accessory… but if you want to go a bit further a team of developers is crowd-funding a project to create an HDMI input board that would let you capture video from a variety of sources. The HDMI input boards will sell for $99 and up if the project meets its $15,000 Kickstarter funding goal.
