The visual information of a surveillance system should provide extended and just-in-time perception in monitored environments. However, delivering visual information of surveillance from nonstationary providers, such as mobile cameras, to designated end-users over bandwidth-limited networks is a challenging task. In this paper, for transmitting visual objects of interest, an embedded spatial coding...
The paper proposes a receiver-based, rate and quality control mechanism. The main principle is to regulate encoding rate to guarantee the video quality is acceptable, especially in region of interest. Transmitting the encoded bit stream in multicast delivery not only improves bandwidth efficiency but also provides different quality for receivers with different length of bit stream. The overall mechanism...
