However in practice, the multi-protocol, multi-format nature of adaptive streaming creates a lot of engineering eort andcosts for the operators, in the storage and preparation of the dierentformats. In this work, we acknowledge these issues and we study a stream-ing setup that can address these. Such streaming setup consist of a backendcloud storage and a processing node that generates streaming presentationsfor different devices on-the-fly. We analyse the streaming setup and itsperformance by testing in cloud deployments. Through this evaluation, weidentify the performance limitations of the setup, imposed by the transferof data between the object storage and the processing node. We propose anew backend storage caching scheme, based on rarely used existing featureof dref in the specication of the MPEG-4 standard. Experimental resultsshow that the proposed scheme can improve the streaming performance,such as reduced latency and increased outgoing traffic volume towards theclients Subject Video streamingMedia File Formats To reference this document use: http://resolver.tudelft.nl/uuid:e06cde4c-1514-4a8d-90be-7e10eee5aac1 Part of collection Student theses Document type master thesis Rights © 2018 Christina Kylili Files PDF MSc_thesis_Christina_Kylili.pdf 2.38 MB Close viewer /islandora/object/uuid:e06cde4c-1514-4a8d-90be-7e10eee5aac1/datastream/OBJ/view
