Fine-grained scalability can adapt most closely to the available bandwidth, but this comes at the cost of a high compression penalty. In the context of VoD streaming to mobile end systems, we have therefore explored whether a similar adaptation to the available bandwidth can be achieved by performing layer switching in coarse-grained scalable videos. In this approach, enhancement layers of a video stream are switched on and off to achieve any desired longer-term bandwidth. We performed user studies to evaluate the idea, and came to the far-from-obvious conclusion that layer switching is viable way for bit-rate savings and fine-grained bit-rate adaptation even for rather short times between layer switches.}, year = {2009}, journal = {International Workshop on Network and Operating Systems Support for Digital Audio and Video (NOSSDAV)}, pages = {103-108}, month = {June}, publisher = {ACM}, isbn = {978-1-60558-433-1}, editor = {Dongyan Ooi}, }
