Conference Object Citation - Scopus: 3Scalable Video Transmission Over Unreliable Networks Using Multiple Description Wavelet Coding(2011) Choupanı, Roya; Choupany, R.; Wong, S.; Tolun, M.; Bilgisayar MühendisliğiScalable video coding (SVC) and multiple description coding (MDC) are the two different adaptation schemes for video transmission over heterogenous and best-effort networks such as the Internet. We present a new approach to combine the advantages of SVC and MDC to provide reliable video communication over a wider range of communication networks and/or satisfy application requirements. Our proposed method utilizes 3D discrete wavelet transform and a modified embedded zero tree data structure to group the coefficients in different descriptions. The proposed method reduces the impact of the drift error by organizing the frames in a hierarchical structure. © 2011 AICIT.Conference Object Optimized Multiple Description Coding for Temporal Video Scalability(Springer Verlag, 2013) Choupani, R.; Wong, S.; Tolun, M.The vast application of video streaming over the Internet requires video adaptation to the fluctuations of the available bandwidth, and the rendering capabilities of the receiver device. On the other hand, the available video coding standards are designed for optimum bit rate which makes them susceptible to packet losses. A combination of video adaptation methods and error resilient methods can make the video stream more robust against networking problems. In this paper, an optimization for combining scalable video coding with multiple description coding schemes have been proposed. Our proposed method is capable of creating balanced descriptions with optimum coding efficiency.
