STK45xx is a high integration Digital Video Recorder and Digital Still Camera controller. The STK45xx features high quality image processor coupled with high-speed bus and video compression engine delivering excellent quality video recording and playback (1080p size 1920x1080 at 30 fps). Innovative image processing architecture reduces memory size requirements in both DVR and DSC mode allowing operation with DDR/DDR2 SDRAM. Sensor interface module accepts 10 bit data delivered by modern CMOS CCD sensors preserving details in shadows and delivering perfect images even for high dynamic range scenes. Syntek proprietary auto white balance and auto exposure algorithms utilize the statistical data analysis to deliver the precise and pleasing colors. Integrated microphone amplifier, AGC and audio codec reduce system component count and deliver clear audio recordings at all sound levels. The STK45xx is also capable of storing MJPEG videos and JPEG compressed pictures on most popular non-volatile/volatile memory or mini-storage cards. Storage interface utilizing fast DMA allows direct recording to the storage media and supports all major industry standards. Other auxiliary features such as TFT LCD panel interface, TV display, audio annotation, recording and playback, programmable user interface logic and power management are all integrated into a single chip.
