Adaptive and integrated video communication for wireless ATM

Highly efficient and robust source coding, channel coding, and packetization techniques are proposed for video streaming over wireless ATM. At the base station, which is located at the boundary of the wireline and wireless networks, video received from the wireline source is dynamically transformed to match both the hardware capabilities of mobile hosts and the time-varying wireless channel conditions. For wireless transmission, source coding, channel coding, and packetization are jointly implemented as part of the application. For source coding, we propose to use our three-dimensional significance-linked connected component analysis video codec. For channel coding and packetization, both intracell and interlaced (intercell) forward error correction are applied. Furthermore, the time-varying channel characteristics is exploited by adaptively allocating the total bit budget between source coding and channel coding. Extensive performance evaluation demonstrates the effectiveness of the proposed wireless video streaming technique.
