Intelligent satellite-based visual communication over wireless ATM

This paper focuses on satellite visual (image/video) communications over wireless ATM. When compared to computer data, remote sensed imagery requires huge volumes of information to be transmitted in a timely manner. On the other hand, error-free transmission is not strictly necessary at lower layer protocols. This is because more efficient error protection can be designed at the application layer and non-correctable transmission errors may be rendered imperceptible. In the proposed system, compression, transmission error protection, and packetization are jointly implemented as part of the application. For source coding, the authors propose to use their high performance significance-linked connected component analysis (SLCCA) wavelet codec. SLCCA provides multiresolution representation well suited for remote sensing data. They also propose error protection strategies to ensure reliable transmission of satellite data.
