| Abstract: | A multimedia communication terminal based on ADSP-BF533 DSP processor and used in IP network was designed and implemented. μCOS-II embedded operation system was used in the system, with the transplantation of LwIP. The experiments show that by the multimedia communicaiton terminal, the coding and transportation of multimedia information can be realized in real time in LAN. |
