  • 近年來,由於行動網路的普及,以及對HTTP(Hypertext Transfer Port)串流需求的提升,有越來越多的線上平台提供多媒體串流服務,然而我們可以發現,在這些服務平台之中,冷門影片的數量遠大於熱門影片的數量,因此,若能夠有效率的由以上這點來節省儲存空間會是個值得研究的議題。而在漸漸普及的家用網路儲存系統(Network Attached Storage, NAS),沒有企業及網路服務的大儲存空間,對儲存空間的管理則會更加的重要。再者,對網路串流服務來說,能夠跨平台播放是現在的趨勢,而國際動態影像專業組織MPEG所提出的Dynamic Adaptive Streaming over HTTP (DASH) 協定正好符合我們的需求,因此,本篇論文提出了基於Kernel Moving Average (KMA) 之DASH線上即時編碼系統,能夠當使用者播放多媒體內容時即時地編碼來解省儲存空間。


    Nowadays, there is an increasing requirement for HTTP streaming over the mobile network. Lots of online platforms provide multimedia streaming services. We can find that the quantity of videos that few people saw is much more than the one of the popular videos. Hence, it is necessary to save storage on the server due to a large amount of multimedia. It is the same to save when storing these video contents on personal Network Attached Storage (NAS), whose capacity is much limited. Moreover, an efficient HTTP streaming service should adapt to the network condition. Therefore, we proposed a real-time transcoding scheme for Dynamic Adaptive Streaming over HTTP (DASH) based on the Kernel Moving Average (KMA) scheme. KMA is used to estimate the network throughput. The scheme can transcode the video instantly according to the estimated result. Comprehensive experiments validate the concept proposed in this study.
