Abstract: This paper introduces a lightweight super-resolution (SR) network to upgrade low-resolution/-quality videos and SR-WISH, a novel adaptive bitrate (ABR) algorithm, that leverages SR networks at the client to improve the video quality depending on the client’s context. Existing results indicate that the proposed SR network can significantly improve video quality compared to traditional approaches. SR-WISH takes into account mobile device properties, video characteristics, and user preferences.
