Abstract: The paper discusses the TV signal collecting system based on double core ARM+DSP.The CPU of this collecting system makes use of TMS320DM8168 by T1 Corporation.The DSP core of collecting system achieves the TV signal collecting and compression,and the ARM core finishes the task of transferring the data to video server.This collecting system makes use of Linux operating system,which functions to manage  the hardware and the software.The tasks of developing software is the transplant of operating system,the compiling of driving program and the programming of application software.This collecting system can operate at lower cost and power consumption than those by traditional PC visual collecting card construction.

Key words: double core of ARM+DSP, TV signal collecting system, Linux operating system, driving program
