The transmission of animated 2D graphics via the wireless link of the personal digital assistant (PDA) system is investigated in this work. An animated graphic sequence is often stored in the animated GIF format and transmitted via wired networks. Due to the much narrower bandwidth requirement of a wireless channel, the same approach cannot be properly used in the wireless environment. This paper presents a new approach to wireless transmission of animated sequences. Basic elements of 2D graphics include points, lines, polygons and different color filling commands. Furthermore, to achieve the animation effect, a reference frame is often used to reduce the redundancy between adjacent frames. All these can be considered as rendering commands. The major different between 2D graphics and the GIF image is that the former is on structure level while the latter is on pixel level (i.e. bitmap). By exploiting this unique feature, we are able to obtain a more efficient coding method for the component frame. That is, instead of transmitting the rendered bitmap as done with animated GIF, rendering commands are encoded and transmitted to client's PDA while the rendering process is actually performed at the client side. With the proposed scheme, the compression standard is built upon a common set of rendering commands. The final integration involves buffer control and error protection. It is demonstrated by experiments that animated sequences can be transmitted within a channel of bandwidth less than 1 Kbps while maintaining excellent image quality.
