A fast rate adaptation scheme for SVC based on the packet dependencies
The Scalable Video Coding (SVC) standard offers multiple scalabilities while maintaining high coding efficiency. However, the joint coding of multiple scalabilities complicates the rate adaptation as the SVC packets possess different priorities. To address this challenge, we propose in this paper a...

| description | The Scalable Video Coding (SVC) standard offers multiple scalabilities while maintaining high coding efficiency. However, the joint coding of multiple scalabilities complicates the rate adaptation as the SVC packets possess different priorities. To address this challenge, we propose in this paper a fast rate adaptation scheme for SVC in absence of the original video sequence. Specifically, we present an efficient algorithm to extract the SVC bitstream by a packet prioritization scheme, which is based on the analysis of packet dependencies (PD) in encoding of full scalability. Experimental results demonstrate that the proposed scheme achieves significant improvement in PSNR over the basic bit extraction scheme in SVC and attains comparable PSNR performance to the Quality Layer based rate adaptation scheme while significantly reducing the computational cost. |
