System and method for processing multimedia information of sensor network based on OMAP (Open Multimedia Application Platform)

Abstract

The invention discloses a system and method for processing multimedia information of a sensor network based on an OMAP (Open Multimedia Application Platform). The system for processing multimedia information of the sensor network based on the OMAP is characterized by comprising an ARM (Advanced RISC Microprocessor) and a DSP (Digital Signal Processor) of the OMAP, wherein the ARM is mainly used for controlling the whole system; the DSP is mainly used for processing the multimedia information; and the ARM communicates with the inner part of the DSP through sharing the RAM; a sensor information module, a video information module and an audio information module which are connected with the DSP processor under the control of the ARM microprocessor; and an intermediate- and high-speed transmission interface module, a serial port module, a power management module, a GPS (Global Position System) module, a touch screen module, an upper computer and a WIFI (Wireless Fidelity) module which are connected with the ARM. The system and method for processing multimedia information of the sensor network based on the OMAP disclosed by the invention adopt an OMAP dual-core structure with excellent performance so that multimedia information such as audio / video and various sensor data can be acquired, sent, received and processed in real time; and the system and method for processing multimedia information of the sensor network based on the OMAP disclosed by the invention can be widely applied to fields, such as military reconnaissance, public security and the like as well as have very strong practicability.
