Abstract
As handheld computing devices and cell phones become commonplace, streaming media to these devices becomes a challenging problem. This is a result of severe bandwidth, processing, and memory constraints imposed by these devices. Bandwidth limitations necessitate effective compression strategies while memory and processing constraints require inexpensive decompression techniques. This need for highly asymmetric compression and decompression techniques is not well addressed by conventional standards such as MPEG. In the absence of a universally accepted standard, it is highly desirable to bundle lean media handlers with the media itself. Advances in infrastructure for mobile code (fast virtual machines, embedded device support) have enabled development of such active streams - media streams capable of self manipulation. In this paper, we describe a highly asymmetric compression/ decompression technique, called 2D-PMC and an associated mobile decompressor called MOBILVIDEO. We demonstrate that the overhead of using mobile code in our framework is minimal, the compression comparable to MPEG2, and decompression possible in real time at 320 240 resolution (the display resolution of an iPAQ 3870) and 20 FPS even on 206 MHz StrongARM class processors.
