A sample of some of our Video and Telecommunications
projects are described below. Additional project information
including Industrial Control projects are available
by emailing design@itsus.com.
Architected & designed sections of
the Nuko MPEG to ATM mux. The design was a VME based
system that took 9 video inputs of MPEG data and statistically
muxed them onto OC3. The work involved the ATM section
of the module and was implemented with Altera 9000 series
FPGA's. Patent Digital Video TDMA Mux 6,088,360.
Nuko ATM MPEG-2 Demultiplexer - AAL5 reassembly
of MPEG-2 video streams from a 155MB/s (OC-3) link.
Wrote all ATM firmware using C and Assembly for LSI
ATMizer SAR, designed FPGAs using Verilog to implement
serial data protocol and handle OAM messaging and monitor
interface.
Architected & designed sections of
the Artel CS155M. The CS155M was Altera 10kXXX based
design that delivered 64 MPEG video streams and muxed
them onto OC3. The system features a context switching,
multi-threaded ATM atomizer interface with table based
traffic shaping . The interface used a SUNI chip for
the ATM PHY and interfaced with the CS155M switch fabric.
The interface also incorporated a Utopia arbiter to
allow Odetics expansion cards to be used.
Architected & designed sections of
the Artel CS155D. The CS155D received multiple MPEG
video streams over OCS3 and de-multiplexed them onto
multiple ASI interfaces. Designed a custom, patented
ATM interface to perform multi-layer switching functions
on an AAL-5 encapsulated MPEG video stream. Patent pending
Digital Video Packet Network 20020024970 .
Architected AAL-1 Digital Video Broadcast(DVB)
demultiplexer to accept an
interleaved Reed-Solomon encoded video stream and perform
error correction
and transport stream reconstruction.
Frame-Relay Module - An interface for
6 T1/E1 ports to an Ethernet
interface. Developed FPGAs using Verilog to configure
and control Motorola
PowerPC processors and to provide bus arbitration and
control for PCI bus.
Digital Video Broadcast (DVB) Scrambler
- Scrambling (encryption) of a
serial MPEG-2 stream. Developed proprietary host RS-232
interface using an
8051 microcontroller and custom logic to handle host
processor communication and generate encryption keys.
Developed all run-time code using 8051 Assembly language.
Developed a specialized hardware and software
solution for a Broadband
service provider to perform clock-recovery of satellite-broadcast
video for
an ATM-based video distribution network. Modified existing
hardware and
wrote software application using C.
