April 17, 2003 Document Rev B
EM2700/2800 USB2.0 Video Controller is a highly integrated VLSI that provides a cost-effective solution for video capture application. As illustrated in the system block diagram, a PC-camera subsystem requires only three chips: CMOS imager, EM2700 and AC 97 codec. Application of such a system can be video phone, video mail. A video capture solution requires three chips only: Video decoder, EM2800 and AC 97 codec. Application of such a system can be TV on PC, Camcorder video capture and editing. As shown in the functional block diagram, the EMPIA-2700/2800 consists of 6 main blocks * Video/Audio Input Port * USB 2.0 Transceiver * Compression Engine * GPIO, Two Wire Serial Bus, AC 97 Interface * USB 2.0 Serial Interface Engine * Color Enhancement
