Design and implementation of an MHP video and graphics subsystem on Xilinx ML310 platform

Abstract

Multimedia Home Platform (MHP) is a standard to enable versatile applications of a DVB program. In this paper, we design and implement a simplified MHP video and graphics subsystem. The Xilinx ML310 is chosen as the hardware platform to implement our design. The execution environment consists of an embedded Linux, a frame-buffer based X server, and a Java ME Personal Basis Profile,(J2ME PBP) run-time. To implement the MHP video functionality, we incorporate the FFmpeg libraries and the JavaTV JMF Lite to provide the demultiplexing and rendering operations of an MPEG-2 video. In addition, our major efforts are put on the video and graphics integration. The J2ME PBP reference software is heavily modified to optimally compose the video objects and the AWT graphics components in an MHP-compliant way. The application examples show that our proposed system is able to provide the AWT graphics and the JMF video presentation services, including normal presentation, arbitrary clipping scaling and positioning of an MPEG-2 video.
