【摘要】 对标准的视频编解码标准(如H.264和AVS标准)的核心技术进行了分析,提出一种基于TI公司的OMAP3530处理器平台的通用视频解码方案。该方案充分利用了OMAP3530的硬件结构特点,特别是2D/3D图形图像加速器的特点,以提高解码速度。实验结果表明,AVS格式的QCIF码流解码速率可以达到25fps,适合于便携式多媒体终端视频解码应用。更多还原

【Abstract】 The key technology of video coding standard such as H.264 and AVS is analyzed. This paper proposes a video decoding structure based on TI OMAP3530 processor. OMAP3, especially the 2D/3D graphics accelerator, is used to increase the decoding rate. Experimental result shows that decoding frame rate for QCIF of AVS format is 25 fps which can satisfy the needs of real-time playing on portable multimedia terminals.更多还原
