HDMI is the most interesting not only because it is new, but because of the usage scenarios it could enable were the full capabilities of the connection provided. The top breakout/TOSLINK combo provides input and the bottom output for audio/video pass through anytime the PC is powered including standby (S3), hibernate (S4) and soft-off (S5) states. Looking at the native inputs we find HDMI, two breakout connectors for component (YPbPr) / stereo audio, two TOSLINK (optical S/PDIF), and a port to attach the infrared (IR) receiver/blaster. I have one in the parts bin so it was possible to test the feature, which adds s-video and a second composite/stereo capture option to the options provided directly on the device. To utilize the auxiliary inputs a daughter card (not included with the Colossus) is required. There is not much to point out besides the lack of any cooling on the ViXS encoding chip and the presence of Hauppauge’s standard analog connection header along the top.

The single slot, full height PCIe x1 card has a simple layout with all of the components exposed.
