Additionally, these set-tops supportMultimedia over Coax Alliance (MoCA™) technology, which lets subscribers use theircable wiring for LAN connections.The 4642HD and 4652HD set-tops support tru2way™ (formerly OCAP™). The set-tops also offer MPEG-4 (H.264)high definition (HD) and standard definition (SD) decoding with HD and SD outputs and DOCSIS® 2.0 datacapability. The 4652HD set-top also provides analog tuning.Figure 1. Cisco Explorer 4652HD Front Panel (image may vary from actual product and specification)FeaturesNetwork Utilization Enhancements● 1 GHz Tuning enables cable operators to expand network bandwidth to provide additional services suchas VOD, tru2way, DOCSIS 2.0, and high-speed data● MPEG-4 (H.264) Decoding supports compression technology that provides better video quality atapproximately half the data rate of MPEG-2● DOCSIS 2.0 provides greatly increased upstream throughput for future advanced services and provides apath for future IP video services (optional software)OpenCable™ and Conventional Network Support● PowerKEY® Conditional Access System secures digital services using symmetric encryption algorithmfor content protection● Axiom™ Middleware supports tru2way applications such as Service Navigators, Games, and other futuretru2way applications (optional software)● DSG (DOCSIS Set-top Gateway) provides a powerful standard transport mechanism for command andcontrol signaling between the set-top and service provider network (optional software)● DAVIC Receiver/Transmitter allows IP-based, real-time, two-way communication between the set-top andservice provider network for on-demand services (optional software)
