Colossus is a High Definition video recorder for making real-time H.264 compressed recordings at resolutions up to 1080i. HD PVR records component video (YCrCb) from video game consoles and cable TV and satellite set top boxes, with a built-in IR blaster to automatically change TV channels for scheduled recordings.

Colossus also has an HDMI input port, so you can record HD video at up to 1080i from a un-encrypted HDMI source.

Audio is recorded using two channel stereo or optical audio with five channel Dolby Digital.

The recording format is AVCHD, which can be used to burn Blu-ray DVD disks. Two hours of HD recordings, recorded at 5 Mbits/sec, can be burnt onto a standard 4.7 GByte DVD-R or DVD-RW disk for playback on a Blu-ray DVD player.
