Conference Object Citation - Scopus: 3Scalable Video Transmission Over Unreliable Networks Using Multiple Description Wavelet Coding(2011) Choupanı, Roya; Choupany, R.; Wong, S.; Tolun, M.; 1863; Bilgisayar Mühendisliği; 06.01. Bilgisayar Mühendisliği; 06. Mühendislik Fakültesi; 01. Çankaya ÜniversitesiScalable 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.
