Abstract: A Unified Content Delivery Network system (UCDN) system which is formed from a network of one or more inter-operable Peer networks. A hierarchical hybrid adaptive Secure Peer-Assisted Networking System (termed SPAN-AI),using a hierarchical AI driven approach under a unified secure content-addressable architecture which is based on five key SPAN-AI sub systems: unified naming; unified discovery; hybrid adaptive routing; scalable pubsub; and embedded security; all of said five key SPAN-AI sub systems securely integrated and jointly optimized via a hierarchical, pluggable AI framework, with an associated simulation, training, and development pipeline that embeds AI agents with varying degrees of awareness and optimization capabilities at peer, edge, or core or other network levels (hierarchies).

Abstract: An electronic program guide (EPG) having a variable indicator to focus a user's attention upon a corresponding field of a selectable program instance The EPG includes a user interface screen for providing a plurality of television program instances by time and channel in a grid menu. Each television program becomes selectable from the EPG based upon user interaction. The indicator is depicted in association with each television program when it becomes selectable as a result of user interaction. The indicator is configured based upon attributes of the currently selectable program instance.
