The set-top terminal includes a central processing unit, a unified memory architecture, a memory management unit, communications circuitry, I/O control circuitry, and audio and video output circuitry. Through these components, the set-top terminal provides advanced cable services such as a comprehensive channel navigator, an interactive program guide, impulse Pay-Per-View, Near-Video-On-Demand and Video-On-Demand programming, and advanced configuration controls. The set-top terminal also provides online services such as World Wide Web browsing, Internet e-mail, and home shopping.
