Abstract: The present disclosure provides a system and methods for determining and reserving an optimized amount of required cloud instance resources in order to provide quality streaming to viewers while also reducing overhead costs. For content providers, the choice of appropriate cloud location to transcode the live streams and appropriate number of video representations to serve the current viewership is a key in minimizing cost. However, this task cannot typically be done on the fly due to the properties of live streaming characterized by its dynamic, heterogeneity and wideness. The provided system helps predict the incoming load and the exact number of resources to allocate at each cloud site to help prevent the content provider from over-provisioning resources, leading to an extra cost, or under-provisioning resources, leading to viewers' dissatisfaction.

Abstract: The method and apparatus for angle of arrival estimation are used for estimating the angle of arrival of a received signal by a switched beam antenna array and a single receiver. The switched beam antenna array first collects an omnidirectional signal to be used as a reference signal. A main beam thereof is then switched to scan an angular region of interest. The collected signals from the switched beams are cross-correlated with the reference signal. The cross-correlation coefficient is the highest at the true angle of arrival and relatively negligible otherwise. The collected signal from each beam angle is cross-correlated with the omnidirectional reference signal to determine the angle of arrival of the received signal.

Abstract: We provide a method of compressing a data stream for transmission, including: generating a data sequence representing a received data stream, generating a plurality of data substreams, each comprising a portion of the data sequence, identifying a formal concept defining a dependency between a first one of the data substreams and one or more further ones of the data substreams that are dependent on the first data substream, removing those dependent data substreams from the plurality of data substreams, and transmitting the remaining data substreams, and a method of reconstructing a data stream at a receiver, including: receiving a received data sequence representing a received data stream, identifying that a substream has been removed from the data stream prior to transmission, identifying a formal concept definition for regenerating the removed substream based on an identified substream of the received data sequence, regenerating a data substream using the formal concept definition and the identified substream of the received data sequence, and adding the regenerated data substream to the received data sequence.
