SAS kernel: streaming as a service kernel for correlated multi-streaming

Abstract

This paper presents a novel paradigm of Streaming as a Service (SAS) to model correlated multi-streaming in Distributed Interactive Multimedia Environments. We propose SAS Kernel, a generic, distributed, and modular service kernel realizing SAS paradigm. SAS Kernel features high exibility by employing a configurable interface to allow for input of correlated multi-streams (bundle of streams) from diverse types of sensory devices. It is also highly extensible by allowing user-controlled functions to be applied to bundle of streams in runtime. Experiments with real-world applications demonstrate that the SAS Kernel incurs low overhead in delay, CPU, and bandwidth demands.
