A Cloud Service for Adaptive Digital Music Streaming

In this paper we present an adaptive digital music streaming cloud service based on the Amazon Web Services; the players are applications running on mobile devices connected to the Internet via cellular or via wireless networks. Adaptive streaming means that the data rate is determined dynamically function of the available network bandwidth, as well as power reserves of the mobile device. The service applies lossy compression to high quality audio files stored on the cloud to lower the data rate at a level determined by the resources available. We analyze the results of experiments with real-time data conversion for adaptation to the bandwidth available to mobile devices such as smart phones and tablets.
