Design Considerations
The typical IP video phone is a compact, all-in-one desktop phone that takes the complexity out of video conferencing and allows free person-to-person video calls anywhere in the world over a broadband IP connection. These products provide large and small enterprises, government institutions and educational environments with tools to be more productive, train and educate more efficiently, and avoid the burden of travel expenses. As IP network deployments continue to grow, consumers are looking for additional features and integration of video streaming capabilities in a cost-effective fashion.
LCDs high-performance, DSP-based IP video phone solutions enable a number of features including:
real-time multichannel video integration to existing IP voice phones;
three-way video conferencing;
and real-time synchronization of video with voice across IP networks.
Additional DSP MIPS are also available for integration of other features and processing requirements. TIs TMS320C64x™ generation of DSPs execute at clock speeds of 600 MHz, providing an optimal solution with headroom left over for incorporating new features.
A single TI C64xTM generation of DSPs can execute the following functions:
real-time image capture processing;
compression and decompression;
color space conversion and real-time display;
and IP packetization on multiple video streams simultaneously.
