Abstract :
A wireless video processing module using TI´s DaVinci chip TMS320DM6446 as the main chip is described in this paper. In this system analog video signal is digitized by a high speed video decoding circuit and computed by the DSP chip and transmitted over by model of 3G wireless network. The paper describes the design scheme of the wireless video processing module hardware in detail. The hardware is made up of a special video decoder TVP5146, FPGA and DSP, and the circuits include video processing, wireless communication and interface circuits.
