NeTV - Open Source Hardware HDMI overlaying & video compositing

NeTV enables overlaying your web content on existing HDMI video feeds, such as those from a BluRay player or cable box.

Inside, it's an Angstrom linux box running Webkit that features chroma-key video compositing. Out of the box, the reference firmware enables the overlay of Facebook and Twitter feeds, and SMSes from Android phones. The UI is written in Javascript/HTML, making it easy and fast to develop your custom application.

The system also features a convenient HTTP API which uses POST commands to issue events to the screen and control device behavior. This, combined with zeroconf discoverability via Bonjour, makes integrating NeTV with other networked devices (such as your smartphone or laptop) a snap.

FPGA geeks take note! NeTV does video compositing with an FPGA. The FPGA is managed using a convenient set of built-in command-line tools. You can modify the NeTV's video processing capability using Xilinx's free Webkit development environment. Or, you can repurpose the FPGA for entirely new functionality.

• Command line and kernel development via downloadable gcc environment, or via cloud-based "pre-built" Amazon EC2 environment.
• Verilog/VHDL hardware development on FPGA via Xilinx Webpack tools
• Solder-and-screws hardware development enabled via open source hardware stack

• Board Size: 94mm x 57mm
• 800 MHz Marvell PXA168 CPU (Marvell(R) Sheeva(TM) PJ-1 ARMv5TE-compliant with Intel WMMX2 extensions; 32kB/32kB L1 cache; 128kB L2 cache)
• 128 MB DDR2 DRAM, 16-bits x 800MT/s
• 1 GB microSD card pre-loaded with Angstrom-derived Linux distribution * User-accessible Xilinx Spartan-6 XC6SLX9 FPGA
• HDMI input and output ports, compatible with pixclock speeds of 95MHz
• Native resolution support for 480p, 576p, 720p, 1080p/24, 1080i/60
• Video overlay on HDCP encrypted feeds
• MicroUSB port for power and USB gadget support (attaches as ethernet device)
• Embedded 802.11b/g wifi card
• IR receiver
• IR extender port
• Pushbutton that triggers easy to use wifi-based firmware recovery mode

Kit contains:

• NeTV PCB board and IR remote
• NeTV plastic enclosure kit: This is the plastic enclosure for an NeTV PCB. This lovely little box is made of two injection molded halves, a soft rubber anti-slip bottom, and a small baggie of screws. Assembly is simple and only takes a few minutes. Attach the NeTV using the short screws to the bottom plate. Remove the paper backing from the antenna and stick to the underside of the top piece, then fit the large top over it and snap in place. Screw in the 4 longer screws from the bottom. Finish by applying the rubber mat piece to the bottom to hide the screws. You're done!
• 5V 1A USB power supply
• MicroUSB cable
• HDMI cable

NeTV is the first offering from the brand new Sutajio Ko-Usagi, the Open Source Hardware company led by "bunnie" Huang. bunnie is best known as the author of "Hacking the XBox" and was the lead hardware engineer of the chumby internet alarm clock. So, it is no surprise that his latest invention, conceived in chumby industries' Singapore office and brought to you by Sutajio Ko-Usagi, is a fully open source HDTV peripheral which brings WiFi Internet and Android mobile interfacing to any HDMI TV!

NeTV is available here in bare board form with an optional DIY plastics kit! This package does not have the enclosure fully assembled with the PCB, you will have to snap the NeTV into its case, a 5-10 minute task. This package contains the NeTV assembled and tested board, IR remote (to control the NeTV from your couch), a Micro-USB cable (to connect/power the NeTV), a 5V 1A USB power supply (to power the board), and an HDMI cable (to connect it to the HDTV)

From Hack-A-Day:

Check out the new set-top box on the block, the NeTV from Chumby Industries. That link will take you to their video demonstration of the device, which is a humble-looking black box with no apparent user interface. You’ll see a few cool tricks that may impress you, like pairing the device with an Android phone through the use of a QR code. Once the two have mated you can do things like share images on the TV and load webpages from addresses entered into the smart phone. There are options for scrolling alerts when you receive an IM or SMS, and a few other bells and whistles. All of this from a device which connects with two HDMI ports to sit between your TV and whatever feeds it a video signal. Read all about the features here.
But its the hacking potential that really gets our juices flowing. The developer page gives us a look inside at the Spartan-6 FPGA that lives in the little case. We don’t often quote [Dave Jones] but we’re certain he’d call this thing ‘sex on a stick’. They’ve made the schematic and FPGA information available and are just begging for you to do your worst. The power for the device is provided by a USB connection but curiously is just above spec when drawing a max of 700 mA. We have a USB port on the back of our TV and would love to velcro this thing in place and power it from that. What would you plan to do with it?
