Broadcom 7401 System-on-a-Chip, MIPS 5K CPU, 256 MB RAM, 160 GB Hard disk, dual MPEG encoders, dual CableCard support, including support for M-CARD. The two tuner-demodulator units can be seen on the lower right-hand side, and the two CableCARD slots are at the upper edge.
I was a key member of the system software team for this product, and worked on a wide range of its software components, including tuner/demodulator bring-up, the CableCARD interfaces, device drivers, and the media pipeline.
