Game Lovers- Got an Upgradation to your HDMI Input

By Samidha Verma June 23, 2016

Christian Moser on his “techtalk” website has brought technology to a next level. In his post, he has built Bottom of Forma Hyperion Ambilight for every HDMI input source like PS3, XBOX, Chromecast. He has previously dealt in the same technology, while providing an initial ambilight effect for the media center running on the Raspberry pi.

Equipment

The most essential part is the AVR receiver as most of the TV’s don’t offer an HDMI output. Then a HDMI to Analog converter with 1080p support and 2 port HDMI splitter is needed. Further, USB Video Grabber, Composite cable and an Active USB Hub is all you need.

Working

While making this project, Moser transform the digital HDMI signal to an analog composite one with a converter to get the color information from an HDMI input signal. The composite signal is grabbed with an USB video grabber which is connected to the Raspberry Pi and hence, feeding Hyperion with the color information by the video grabber.

Wire it up by connecting the HDMI output from AVR or from HDMI splitter to the HDMI / Composite converter input. The composite cable is used for connecting the USB video grabber with the Composite converter analog output. Then the USB video grabber is plugged into the active USB hub and the hub is connected to the Raspberry Pi.

The analog output to the grabber is connected, if already have a running media center. In whatever situation, make sure that the existing media center is capable of playing media to both outputs, simultaneously. After the setup is connected, video capturing from HDMI input is possible.

Now switch to USB Video Grabber setup and connect the USB Video Grabber to the Raspberry. After all sorts of coding and connections which is already available on the website of Moser, when the HDMI source on AVR is switched on to non HDMI sources, the LED’s will light up in blue. As blue is the default color in case no video source was detected for many AVRs.

Complete video and details are available on the website
