TI's Flagship DSP Delivers Superior-Quality Videoconferencing

INDUSTRY'S FIRST SINGLE-CHIP IMPLEMENTATION OF H.320 VIDEOCONFERENCING
STANDARD

HOUSTON (May 2, 1995) -- By combining the two billion-operations-per-second
horsepower of the TMS320C80 (MVP) with a software implementation of the
international H.320 videoconferencing standard, Texas Instruments
announced today a complete digital signal processing solution providing
full-motion video with image quality superior to any other H.320 chip or
chip set implementation. TI's DSP solution is already helping
videoconferencing customers design systems that will revolutionize the way
we communicate.

First demonstrated at the CeBIT conference in Hanover, Germany, March 8-15,
the new 'C80 implementation of the H.320 standard puts TI at the forefront
of the videoconferencing market. It moves the company toward a major DSP
marketing objective: To become the world leader in videoconferencing
solutions in 1996. It also opens the door to quality videoconferencing on
millions of desktop computers.

TI's highly integrated 'C80-based solution is the only product available
today that takes maximum advantage of the H.320 standard to produce
superior-quality video, while other silicon makers are offering chipsets
that merely comply with the standard.

High-Quality Video+Audio+Software on a Single Chip

The 'C80 is the first videoconferencing solution to integrate H.320 video
compression/decompression as well as audio compression/decompression on a
single chip-compared to comparable chipset solutions which must separate
the video and audio processing into several devices. The new TI H.320
software library includes standard H.261 video compression along with
audio modules G.728, G.722 and G.711 and communication modules H.221,
H.242 and H.230.

"In a cooperative development with IAT and IBM, Deutsche Telekom has
developed a TMS320C80-based interactive point of sales/point of
information system using H.320-based video communication over ISDN lines,"
said Gerhard Gatzmann, product manager for multimedia systems at Deutsche
Telekom AG. "We will introduce this system to the market in the second
half of 1995. Because of the 'C80's full programmability, we can optimize
our system to offer additional features and have the flexibility to
quickly react to the requirements of our customers. In addition, the
extraordinary computing power of the 'C80 is critical for a high-quality
audio/video communication system such as ours. TI's DSP solution, based on
the 'C80, allows Deutsche Telekom to adapt our product offering according
to the market's requirements."

According to 'C80 marketing manager Julie Gallagher, "As proven at CeBIT,
the quality of TI's 'C80-based H.320 videoconferencing solution stands
head-and-shoulders above the rest of the competition. The demo tells the
whole story."

Gallagher added, "Many of the H.320 systems available today appear to
include such minimal implementations of the standard that the resulting
quality is, essentially, unusable. I think that seeing these poorer
implementations has given a lot of people the idea that H.320 is
inherently poor. With a 'C80 implementation, the standard can provide
video quality that is significantly better than most people have come to
expect from videoconferencing."

TI's new solution achieves superior video quality because of the
processor's ability to perform two billion operations per second. In
addition, the 'C80's full programmability, far greater than other H.320
chipsets, allows customers to take better advantage of compression
standards today and support video quality enhancement techniques in the
future-all on a single chip.

TI's H.320 implementation is just the beginning of the TMS320 DSP
department's commitment to the videoconferencing and video telephone
markets. TI will also support the new H.324 video phone and
videoconferencing standard on the TMS320C80 and its derivatives. The 'C80
also can support a wide range of compression algorithms, including JPEG,
MPEG and other industry standards to integrate a wide range of multimedia
functions on a single add-in board.

'C80 Development Tools Enable Differentiation

A complete set of software tools allows developers of videoconferencing
systems to add their own enhancements either within the standards or with
proprietary techniques. The programmability of the 'C80 and the software
tools not only encourage product differentiation, they also facilitate
upgrades to take advantage of advances in audio and video compression.

Industry's Highest-Performing DSP

The 'C80 integrates on the same silicon four 32-bit advanced DSPs, a 32-bit
RISC processor with a floating point unit, a video controller with dual
frame timers, a transfer controller, and 50 Kbytes of memory. The
industry's highest-performing DSP, the 'C80 is capable of handling more
than two billion operations per second, which represents a ten-fold
increase in performance over previous DSPs.

H.320 Software Library Availability

TI's H.320 software library is available now direct from TI under license
in a variety of forms depending on customer needs. TI offers source code,
object code and mixed source/object code. Future developments to meet end
users' increasing multimedia requirements are slated to include real-time
MPEG record and playback and V.34 modem capability.
