Optimized adaptive HTTP streaming for mobile devices

In this paper we present a solution to improve the performance of adaptive HTTP streaming services. The proposed approach uses a content aware method to determine whether switching to a higher bitrate can improve video quality. The proposed solution can be implemented as a new parameter in segment description to enable content switching only in cases with meaningful increase in quality. Results of our experiments show clear advantages of using additional parameter in DASH implementation. The proposed approach enables significant bandwidth savings with minimal decrease in quality. It guarantees optimal path of adaptation in various scenarios that can be beneficial both for network providers and end users.
