Universal Multimedia Player Based on
DaVinci™ Technology
Benefits
• High-performance,
cost-effective solution
• Easy upgrades and
maintenance due to
modular architecture
• Upgradeable audio and
video codecs
The ATEME Universal Player solution utilizes Texas Instruments TMS320DM644x digital
media processors based on DaVinci™ technology. This powerful solution allows the
best-in-class TMS320C64x+™ DSP core to handle all audio and video codecs, including
MPEG4, H.264, DivX, Nero Digital™, Windows Media® Video version 9, MPEG1, MPEG2
and JPEG, while the ARM9 processor, running Linux OS, handles application control
including GUI, OSD, streaming and content management.
