The flexible SkyScraper™ system is
versatile and provides a highly flexible, end-to-end environment for content
distribution applications, using ATSC or DVB data broadcast standards, or
other broadcast/ multicast media.
DataHub
Simplifies Bandwidth Control DataHub's primary functions are:
•
Allocate bandwidth among multiple content providers by
date and time
•
Receive content flow schedules from DataFab
•
Retrieve content items from source locations and
insert them into broadcast streams according to schedules
•
Monitor and report bandwidth usage
To enable this, DataHub:
•
Provides easy-to-use, local and remote user interfaces
•
Interoperates with all major multiplexers and IP
encapsulators
•
Encapsulates files into IP packets, and encapsulates
IP packets into MPEG-2 packets
•
Supports opportunistic and guaranteed content
insertion
DataFab
Simplifies Content Flow Management DataFab aggregates and structures content to be distributed, thereby
fabricating the content framework for end-users.
To do this, DataFab:
•
Runs on a computer with a TCP/IP link to companion
DataHub
•
Provides an easy-to-use graphical user interface (GUI)
for identifying content items to be distributed (by URLs), and defining
broadcast schedules and optionally target receivers for them
•
Schedule content conveniently for distribution through
multiple DataHub, independently or concurrently
•
Monitor content receipt acknowledgements from
receivers
DataReceiver Extracts Content from Broadcasts DataReceiver extracts content from a digital broadcast stream directly to
the end-user's computer or to a network file server.
•
To facilitate content reception and management,
DataReceiver:
•
Presents a directory of extracted content in an
easy-to-navigate graphical user interface (GUI)
•
Supports the receiver targeting function
•
Applies decryption and forward error correction as
needed
•
Auto-launches content on arrival, including software
updates
•
Provides filtering and cache management tools
•
Sends content reception status back to DataHub and
DataFab, if a back channel is available (such as an Internet link or dial-up
line)
