- Power, flexibility, and
advanced security features highlight the Cisco® Explorer® 4642HD
High-Definition Set-Top.
- Additionally, this set-top
supports Multimedia over Coax Alliance (MoCA™) technology, which
lets subscribers use their cable wiring for LAN connections.
-
The 4642HD set-top supports tru2way™ (formerly OCAP™).
-
The set-top also offers MPEG-4 (H.264) high definition (HD) and
standard definition (SD) decoding with HD and SD outputs and DOCSIS®
2.0 data capability.
Network Utilization Enhancements:
-
1 GHz Tuning enables cable operators to expand network bandwidth to
provide additional services such as VOD, tru2way, DOCSIS 2.0, and
high-speed data
-
MPEG-4 (H.264) Decoding supports compression technology that
provides better video quality at approximately half the data rate of
MPEG-2
-
DOCSIS 2.0 provides greatly increased upstream throughput for future
advanced services and provides a path for future IP video services
(optional software)
OpenCable™ and Conventional Network Support:
-
PowerKEY® Conditional Access System secures digital services using
symmetric encryption algorithm for content protection
-
Axiom™ Middleware supports tru2way applications such as Service
Navigators, Games, and other future tru2way applications (optional
software)
-
DSG (DOCSIS Set-top Gateway) provides a powerful standard transport
mechanism for command and control 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 and service provider network for
on-demand services (optional software)
-
ENERGY STAR® Tier 1 qualified set-top box must meet strict
energy-efficiency guidelines set by the US Environmental Protection
Agency (EPA) and the US Department of Energy (DOE)
Home Networking Features:
-
USB 2.0 Connection enables a host connection to peripheral devices
such as navigation controllers, network adapters, and memory media
readers
-
MoCA Connection enables an IP LAN connection over coax cable, which
minimizes the need for new wiring in the home
-
Ethernet Connection enables a connection to the home IP LAN for
advanced services such as content sharing to the set-top from
retail-purchased electronic devices (optional)
