In traditional advertisement push/broadcast applications, a lot of advertisement files will be directly downloaded from telcom operators (or content providers) to subscribers, and more bandwidth resources are needed. However, the server's upload bandwidth might be the performance bottleneck when many files are downloaded at meanwhile. It results in network congestion, incompletely received files and...
UDP is usually used as the mechanism to transmit real-time video data. However, it has no control over the packet it transferred, and unaware of the network condition it is running on, such as packet loss, delay and jitter. As bandwidth is crucial for surveillance system due to its high bit rate and restrict time constraint, we focus on the packet loss problem in this paper which is mainly caused...
The peer-to-peer (P2P) live video streaming system has been demonstrated to have great potential in the public Internet; the large-scale deployment of such systems, however, critically relies on how effective they can deal with the high dynamics encountered, in particular during flash crowd. The rationale behind is that the scaling in P2P live video streaming systems is heavily determined by the timing...
This paper presents a low cost FPGA based solution for a real-time moving object tracking system. A specialized architecture is presented based on a soft RISC processor capable of running kernel based mean shift tracking algorithm. The system includes a frame grabber unit that stores the video frame in DDR RAM using direct memory access, a video display unit to monitor the tracking statistics and...
