Title: | Operations Research Approach Towards Layered Multi-Source Video Delivery | Contributor(s): | Cheok, Lai-Tee (author) ; Eleftheriadis, Alexandros (author) | Publication Date: | 2004 | Handle Link: | https://hdl.handle.net/1959.11/21147 | Abstract: | We address the problem of rate scaling of multiple layered video streams in applications such as a multi-camera video surveillance system. This differs from the single video streaming scenario in that relevant information from all sources has to be aggregated and a collective decision made. We propose a scenario to achieve better granularity in quality adaptation by considering inter-source and inter-layer streaming jointly, using Operation Research techniques to arrive at an optimal or nearoptimal solution. We formulate our Multi-Source MultiLayer Selection (SLS) problem in the form of a MultipleChoice Knapsack Problem (MCKP). We analyze optimal and approximate algorithms to determine their suitability for solving the problem. We present a simple modification based on an existing greedy aglorithm by exploiting some properties of layered video. The modified SLS algorithm is extended to incorporate weights (Weighted SLS - WSLS - algorithm). Via experimental results using MPEG-4 FGS, we show that WSLS improves the performance for specialized applications. We also discuss the various network configurations of a multi-source video distribution system. | Publication Type: | Conference Publication | Conference Details: | PCS 2004: Picture Coding Symposium, California, United States of America, 15th - 17th December, 2004 | Source of Publication: | Proceedings of the 2004 Picture Coding Symposium (2004 PCS), p. 1-6 | Publisher: | UC Davis | Place of Publication: | United States of America | Fields of Research (FoR) 2008: | 080108 Neural, Evolutionary and Fuzzy Computation | Socio-Economic Objective (SEO) 2008: | 970108 Expanding Knowledge in the Information and Computing Sciences | HERDC Category Description: | E2 Non-Refereed Scholarly Conference Publication | Publisher/associated links: | https://pdfs.semanticscholar.org/0fa6/05468083ff361a87231ac31766d88d29a423.pdf |
