摘要：

A scalable video streaming system that includes video preprocessing, differential JPEG-2000 (DJ2K) video codec, and content-aware rate control is proposed. The proposed streaming solution tackles tile problem of maintaining smooth video quality even when there is a significant change in the source content or the transmission bandwidth. The wavelet-based JPEG-2000 video codec provides temporal, spatial and SNR scalabilities. A rate controller, which is separated from the encoder, can deal with diverse demands of a wide variety of users and various traffic conditions in a heterogeneous network by leveraging offerred scalabilities and content-awareness. Simulations are conducted to demonstrate various advantages of the proposed solution.
