A Concurrent Ubiquitous Video Streaming Platform Design Using SVC Techniques and Multi-core Parallelism Programming

Abstract

In the decade, CPU manufacture industries are highly prompting multi-core CPU products, e.g., Intel Core2 Duo and AMD Athlon64 x2. The merit of the multi-core CPU is able to dispatch multiple tasks in distinct CPU cores and boost the execution speed in parallel. In this paper, we design a Concurrent Ubiquitous Video streaming platform using Multi- Core parallelism programming and the scalable extension of H.264/AVC, which is called MC-CUV. The proposed streaming platform is able to serve lots of heterogeneous users who may utilize distinct terminals through distinct network interfaces to get on-demand videos from an ISP streaming server at meanwhile. In our experiments, distinct video’s spatiotemporal resolutions and SNR quality are presented depending on the device capability and network condition. Comparing with the multi-core single-thread streaming approach, the average execution time can decrease effectively because multiple streaming tasks can be executed in parallel using a proposed task dispatcher through multiple CPU cores.
