Abstract: Devices, computer-readable media, and methods for recording a video chunk in a designated order comprising a plurality of intra-frame coded frames followed by a plurality of inter-frame coded frames are disclosed. For instance, a processing system including at least one processor may obtain a video chunk associated with a time block of a video. In one example, the video chunk includes a plurality of frames encoded in a bitrate of a plurality of available bitrates for the time block of the video, and the plurality of frames includes a plurality of intra-frame coded frames and a plurality of inter-frame coded frames. In one example, the plurality of frames is in a first order. The processing system may then record the video chunk in a second order comprising the plurality of intra-frame coded frames followed by the plurality of inter-frame coded frames.

Abstract: A method includes receiving, from a log of client device requests, a plurality of uniform resource locators (URLs) associated with delivery of a media stream to a client device by a network operator from a third party service provider different than the network operator. The method includes determining quality of experience (QoE) metric information from URL pairs of the plurality of URLs. Each URL pair includes a first URL that corresponds to a segment of the media stream requested by the client device and a second URL that corresponds to a next segment of the media stream requested by the client device after the client device requests the segment. The method also includes determining first QoE information for the delivery of the media stream to the client device by network devices of the network operator based on the QoE metric information.

Abstract: Aspects of the subject disclosure may include, for example, receiving network information for a group of video sessions. Embodiments include calculating an overall video traffic metric for the group of video sessions for each cell based on the network information and include determining a first overall video traffic metric of a first cell is above a first predetermined threshold and a second overall video traffic metric of a second cell is below the first predetermined threshold. Also, embodiments include generating a graphical map that indicates the overall video traffic metric for each cell in the cellular network and sending the graphical map to a mobile device in the first cell showing first overall video traffic metric and the second overall video traffic metric relative to the first predetermined threshold. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, obtaining predicted available bandwidths for an end user device, monitoring buffer occupancy of a buffer of the end user device, determining bit rates for portions of media content according to the predicted available bandwidths and according to the buffer occupancy, and adjusting bit rates for portions of media content according to the predicted available bandwidths and according to the buffer occupancy during streaming of the media content to the end user device over a wireless network. Other embodiments are disclosed.
