The IEEE Spectrum article that discussed this scheme mentioned that custom chips were developed to do the job. But could the equivalent be done with a TMS34020 or TMS320C30 on a frame buffer card, with the compressed video fed via the bus from a hard disk? I notice that the Intel system is rather inflexible, in terms of integration into the current mainstream graphics environment (X window, TIGA from TI, etc.) but since both standards do run on the TMS340 family, it might be worth investigating whether the algorithm could be run on those chips also, rather than use Intel's chip set.
