FREMONT, Calif, and LAS VEGAS, Nev., April 7,
2003 – InterVideo, Inc. today introduced
and demonstrated its MPEG-4 Codec application package
in booth SU7126 at the National Association of
Broadcasters (NAB) show. This high-quality codec
uses Tensilica’s Xtensa processor to provide
significant improvements in the performance of
key MPEG-4 algorithms without the requirement for
an expensive video coprocessor. InterVideo’s
MPEG-4 Codec provides encode and decode of QCIF
(176 x 144 pixels)- and CIF (352 x 288 pixels)-resolution
images at up to 30 frames-per-second, ideal for
next-generation consumer video devices including
digital still and video cameras as well as cellular
phones and PDAs. This codec was jointly developed
with InCOMM Technologies Co., Ltd.
InterVideo’s MPEG-4 Codec application package
is a complete solution for system-on-chip (SOC)
designers. It includes optimized MPEG-4 application
code, documentation, and TIE (Tensilica Instruction
Extensions) language extensions to the Xtensa microprocessor
instruction set. Using this package, system developers
can integrate an MPEG-4 codec into a SOC without
the need for additional optimizations or software
development.
By using InterVideo’s MPEG-4 Codec application
package with the Xtensa processor, designers can
implement MPEG-4 QCIF 15 fps decode in only 15
MHz and MPEG-4 QCIF 15 fps encode in only 30 MHz
over a wide range of memory latencies (0-25 cycles).
The optimized package results in an efficient implementation
supporting simultaneous encode and decode in only
45 MHz. Utilizing advanced rate control, superior
quality is delivered at these low clock rates,
making it ideal to provide high-quality video even
over bandwidth constrained wireless applications.
“By optimizing the Xtensa processor for
this specific application, we’re able to
get industry leading performance and outstanding
quality for MPEG-4 video,” said Steve Ro,
founder and CEO of InterVideo. “InterVideo’s
MPEG-4 Codec provides the quality our customers
require for demanding 3G mobile phone applications.”
InterVideo’s MPEG-4 Codec provides full
compliance with MPEG-4 Version 1 (ISO/IEC 14496-2)
simple profile @ level 1,2 and 3 (SP@L1, SP@L2
and SP@L3). High-quality encoding is achieved via
a large motion search range and sophisticated rate
control. Both constant and variable bit rate encoding
modes are supported with enhanced visual quality.
This MPEG-4 Codec was jointly developed with InCOMM
Technologies Co., Ltd., a Tensilica authorized
design center. The MPEG-4 Codec can be integrated
with InCOMM’s comprehensive Xtensa processor
based SOC design platform to meet demanding cost
and time-to-market requirements for wireless and
mobile consumer devices supporting low bit rate
and high quality video. InterVideo will market
and support this product. For more information,
