(English Abstract)
As demand for high-quality video streaming services increases, researches on Hyper-Text Transfer Protocol (HTTP) adaptive streaming based on multipath transmission have experienced a continual rise. In the wireless environment, multipath-based streaming cannot be accurately estimated according to transmission scheme and bandwidth estimation scheme. In this paper, we propose a multipath-based HTTP adaptive streaming and available bandwidth estimation scheme to improve stability and responsiveness in wireless environments. Multipath-based HTTP adaptive streaming is a block-based scheduling scheme for improving the performance of HTTP adaptive streaming. The scheme dynamically adjusts the request period based on the buffer state in order to improve the responsiveness to the rapid change in the network. The available bandwidth estimation scheme enhances stability by using the block and segment based available bandwidth measurement to predict frequent and sudden changes of bandwidth in a wireless environment.
