PCI
Appliance from VideoPropulsion Enables the Next Generation of Scaleable, High
Density, Very Low Cost Per Stream, Video Servers
Slinger, Wisconsin - November 11, 2002 - VideoPropulsion, Inc. has
begun demonstrating its Torrent™ 6 port PCI Quadrature Amplitude Modulator
(QAM) Host Bus Adapter, the newest member of the Company's VDOPump™ family
of high performance, low cost MPEG delivery appliances for open system Video on
Demand (VoD) servers. Using patented architecture and timing mechanisms, the VPI
Torrent™ provides up to sixty 3.8 megabit per second MPEG-2 256QAM output
streams (forty-two 64QAM outputs) via Intermediate Frequency (IF) at a price of
under $100 per stream in OEM quantities. An integral JAVA engine and
multiplexing hardware reduce host CPU overhead substantially.
Onboard
PCI addressable DRAM allows for direct I/O from storage devices to the HexQAM
without transferring in and out of host memory. Software drivers are available
today for Sun Solaris, Windows, and Linux operating systems. Output from a
Torrent connects directly into commodity RF upconverters.
The VPI
Torrent is a powerful, single PCI HBA with six IF QAM output links, CPU, a
buffer/cache of up to 256 megabytes, and a 32/64 bit 33/66 MHz host PCI
connection. Video streams can be pipelined directly from cache, storage and/or
network for playout or from the card, through PCI, to host memory and
peripherals. The VPiTV™ Player application for demonstration, development,
or broadcast environments is included with the appliance. Several Torrent
VDOPumps can run in parallel in a single host. One Torrent will deliver up to
sixty 3.8 Megabit per second streams with content cached in the HBA or host
memory, as well as coming from local or host storage or networks.
VPI
offers the Torrent PCI HexQAM as an individual module or in Solaris and Linux
based systems ranging from 120 streams with 50 two-hour movies to 600 streams
with over 3000 Movies. Systems exploiting the high density and low cost of the
VPI Torrent can be clustered to deliver tens of thousands of streams for less
than the cost of current, standalone DVB or Ethernet based QAMs. VPI will
demonstrate the Torrent in conjunction with the
Broadband Plus Show December 3-6
in Anaheim, CA.
