Today’s integrated digital television receiver decoders, or digital set-top boxes (STBs), are no longer simple audio/video demodulators/de-scramblers. They are graphically-rich multimedia terminals that possess powerful CPUs (> 150 MIPS) and large amounts of embedded code (> 4 MB). Most also include a Java runtime environment as the preferred platform for running applications and supporting interactive digital home entertainment and services. In the future, these devices will continue to evolve by incorporating new technologies such as digital video recording (DVR) and additional modes for connectivity (V.90, DOCSIS, 802.11b, and so on). Sometime soon, they will mature into such complex products as home gateways and media servers.
