Service Architecture
"World-Class Set of Components Designed to Create High-Quality Service Architecture"
GE Americom has assembled a world-class set of components to create the service architecture for IPMulticast".
Existing GE satellites and uplink resources are integrated with existing terrestrial networks to create the infrastructure for a flexible, strategic overlay network resource.
GE Network Operations Center
The Network Operations Center (NOC) is the heart of the IPMulticast" service, where broadband content is received from customers. Content is then prepared and encapsulated in a Digital Video Broadcast (DVB) signal and transmitted to the appropriate GE satellite.
Dial-UP/Internet/FTP
IPMulticast" clients can use a variety of terrestrial communications facilities to deliver content to the Americom NOC for multicasting - including dial-up facilities, FTP, fiber and even satellite broadcast of video content.
Client Publishers
Client publishers provide the source content for IPMulticast". Large data files, multimedia, streaming graphics or video content can be delivered to GE via terrestrial data facilities, or in hard format (CD-ROM, video, or other source).
IPMulticast" Return Path
IPMulticast" is "one to many" communication, so content travels only one way - from the satellite to client locations. To request content or provide input, customers will use the Internet or other resources for the return communications path.
IPMulticast" Packet Forwarder
Each receiving location has an IPMulticast" Packet Forwarder on its network. This server is equipped with an industry standard card that separates content from the Digital Video Broadcast (DVB) signal. The content is either stored on the server for future forwarding, or streamed directly over the receiving locations' LAN.
GE Client Locations
The broadband content is multicast and received at client locations via an inexpensive 1.2 sub-meter dish mounted on a client's building. The content is then sent to each location's IPMulticast" Packet Forwarder.
GE Geosynchronous Satellites
IPMulticast" service will be provided through GE Americom's fleet of 12 state-of-the-art satellites, providing coverage for all of North America, Europe and major portions of Asia and the Pacific Rim.
