Video images converted without framegrabbers
Analogue to digital video converters capture and convert NTSC/PAL video into digital images, then transfer them to a host computer, eliminating the need for plug-in framegrabbers.
Framegrabbers integrated into embedded systems
Real time image capture can easily be integrated into an embedded system. Support for Windows 95/98/200/N, VxWorks (x86) and Linux/RT Linux is provided.
The software is a highly integrated solution with such features as echo cancellation, noise suppression and narrow signal protection.
MAEC is focused on mobile telephony devices, including cellular phones, hands-free mobile sets, car-kits and smart-phone devices.
Wireless mobile devices present new and different challenges to those found in telephony and Internet telephony applications and these challenges have been successfully overcome with Spirit's latest echo suppressing technology.

Ultra fast cameraLink digital video acquisition and real-time processing boards offers real-time pre-processing of the video data.
Converter avoids framegrabber
For people who want to stream analogue NTSC/PAL video into PCs and laptops, where plugging in a framegrabber is not possible or not preferred, a converter does the job.
Superior solution offered for protocol stack
A superior solution is being offered for implementing Internet connectivity in embedded applications based on Texas Instruments' TMS320 DSP: the bf3Net TCP/IP protocol stack.
No less important is a growing requirement to avoid the harmful effect of having mobile phones too close to the head, which has lead to greater use of hands-free devices and high demand for echo free speech quality.
Dramatic improvement in sound quality is achieved through a combination of techniques including: sophisticated full-duplex control, high robustness to the specifics of mobile equipment, such as noise and non-linear distortions, reliable double-talk detector, enhanced non-linear processing and sub-band processing and adaptive filtering.
The software is distinguished by such features as: true full-duplex speakerphone operation, more than -42dB total echo rejection, fast convergence and dynamic adaptation to changing conditions such as noise, speech levels, or delay.
Spirit's Acoustic Echo cancellation software has a proven track record, being integrated in the leading European videophone and e-mailer products.
Spirit's MAEC software is written as fixed-point DSP code, and is readily ported to a variety of DSP or RISC architectures, such as Texas Instruments C54x, C55x, ARM7/9/strong ARM/xscale/Calm16.
