Abstract
Video streaming applications are a major contributor to the recent dramatic rise of data traffic in cellular networks. Mobile users in a cellular network often experience fluctuating data rates, which might affect the quality of video they view in a streaming service. Although replacing such video streaming services with video downloading/renting services could potentially allow such mobile users to enjoy consistently higher quality videos, such services typically cost a lot more than video streaming services because of legal copyright pricing and management issues. By downloading enhancement layers but streaming base layers of the content, mobile users can enjoy download-quality videos with a service (legally) classified as a streaming service.9,173,091, "Lawful interception of unauthorized subscribers and equipments," assigned to Ericsson (SE).
