Paper Abstract

An adaptive and integrated video communication system is proposed for wireless ATM. Video received from the wireline source is adapted at the base station to both the hardware capabilities of mobile host and time-varying wireless channel conditions. Following the application level framing principle, source coding, channel coding, and packetization are jointly implemented as part of the application and only simple services are requested from the underlying wireless network infrastructure. Highly efficient and robust source coding, channel coding, and packetization techniques are also proposed. 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. Performance evaluation demonstrates the effectiveness of the proposed wireless video communication system.
