| Abstract: | A method of MPEG-2/MPEG-4 video stream transcoding,based on DAM6416P image processing hardware platform and DSPs real-time simulator of the TDS560USB,is implemented in this paper.The video stream transcoding consists of main programs at PC and DSPs programs,and input/output data in the form of two-level buffer.The DAM6416P image processing hardware platform uses TDS560USB DSPs with 600MHz as the core,providing the SDRAM with 256M bytes,FLASH with 4M bytes,PCI interface,and accomplishing video stream transcoding between MPEG-2 and MPEG-4. |
