Patent number: 9800912Abstract: A system and method that utilize a learning system to maintain a set of geographical locations indicating an area where network data coverage is poor. When it is determined that a client device is moving towards such an area, the client is forced or instructed to switch to a lower delivery bitrate for video segments in order to force the client's Adaptive Bit Rate (ABR) playback buffer to fill itself with enough low-quality video segments to enable the client to cross the area without video playback interruption. Thus, the client mobile device may be preemptively forced to choose the lowest bitrate specified in a manifest file for the delivered video segments as the bitrate for downloading video segments when approaching the poor coverage area. Hence, the client device can maintain a minimum level of Quality of Service (QoS) when moving through network areas with poor data coverage.Type: GrantFiled: September 12, 2016Date of Patent: October 24, 2017Assignee: ERICSSON ABInventors: Chris Phillips, Charles Hammett Dasher, Michael Huber, Johan Kölhi
