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.
By connecting to the Raspberry PI’s GPIO pins, digital audio connector, and CSI camera connector, the video capture model should let you record audio and video from a camcorder, desktop or notebook PC, game console, or DVD player. Basically anything that has HDMI output can be connected to the HDMI input module.
The team is working on three different versions of the board. The $129 Loop through model has all the features of the $99 basic model, plus HDMI video output and the $149 Deluxe model supports analog audio input, headphone audio output, an IR receiver and optional IR transmitter, among other things.
