Abstract

We present a new proxy-based system to allow public use handheld devices to access instantly to the Low Resolution Picture Taking (LRPT) satellite weather image data and display regional weather image. First the location-based transcoding is done from non frame based satellite image to frame based CIF/QCIF image for handheld device. GPS information from expansion module is used in the location of the region of interest. A robust fixed-length joint source and channel coding scheme is then implemented to achieve robust wireless transmission. Experimental results show that the proposed system is suitable to the time varying, low bandwidth wireless channel and power constraint on wireless handheld devices.
