摘要：
This work addresses the transmission of motion JPEG2000 over JPIP, proposing a Variable Bit-Rate (VBR) server-driven policy aimed to minimize the overall distortion of the transmitted frames. In addition, a block-wise strategy of quality layer truncation is introduced to enhance the quality of transmitted frames containing insufficient quality layers. We pose these matters in a general framework where the server is able to deliver video on-the-fly, without needing computationally intensive processing. Experimental results suggest that the proposed VBR policy effectively minimizes the overall distortion, and that the block-wise layer truncation can be jointly combined with the VBR policy to widely enhance the quality of the transmitted frames.
