This paper considers scalable delivery of streaming video content with advertisements. It proposes a highly accurate waiting-time prediction algorithm that estimates the expected number of viewed ads by utilizing detailed information about the system state and the applied scheduling policy. It also proposes a pricing scheme based on the expected waiting times, which include the ads' viewing times...
This paper proposes an unsupervised method for detecting credits in TV streams. Identifying credits in TV streams allows to precisely determining boundaries of TV programs and hence, to extract specific and high valuable TV programs. The proposed detection solution is based on the temporal stability of opening and closing credits. Consequently, from a linear TV stream, we detect sequences that are...
This paper provides a performance study for securing media streaming based on hash chain methodology. We introduce a new technique that combines the signature of window-based hash chain with redundancy codes for achieving high reliability and robustness against many attacks. Also, the Window technique integrates the Time-Stamped which strongly eliminates the anti-replay attack. It will also control...
Distributed Interactive Multimedia Environments (DIMEs) enable geographically distributed people to interact with each other in a joint media-rich virtual environment for a wide range of activities, such as art performance, medical consultation, sport training, etc. The real-time collaboration is made possible by exchanging a set of multi-modal sensory streams over the network in real time. The characterization...
