Abstract: Devices, computer-readable media, and methods for providing a timeout for an adaptive bitrate streaming video chunk download are disclosed. For example, a processing system including at least one processor may determine a first bitrate for a first segment of a video program based upon an occupancy level of a video buffer of a device, request a first video chunk of the first segment encoded at the first bitrate, determine that the first video chunk is not received within a threshold of a duration of time after the requesting of the first video chunk, and request, responsive to the determining that the first video chunk is not received within the threshold of the duration of time, a second video chunk of the first segment encoded at a second bitrate that is lower than the first bitrate.

Abstract: Aspects of the subject disclosure may include, for example, a method comprising sending a first list of formats associated with media content to a client device via a network, and receiving from the client device a selection of a format from a second list of formats filtered from the first list using filtering criteria. The second list includes formats compatible with the client device. The filtering criteria can be based on performance metrics of the network and on capabilities of the client device. During presentation of the content at the client device in the selected format, transmission of the content item can be dynamically altered in response to a message that the presentation be continued in a different format. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, identifying a region of interest included in a plurality of candidate regions of interest associated with a presentation of a first content item on a user equipment, wherein the first content item includes a panoramic video, comparing first metadata associated with the region of interest to a plurality of metadata associated with a plurality of secondary content items, responsive to the comparing, identifying a second content item included in the plurality of secondary content items, wherein the identifying of the second content item is based on a distance between the first metadata and second metadata associated with the second content item being less than a threshold, and transmitting the second content item to the user equipment responsive to the identifying of the second content item. Other embodiments are disclosed.

Abstract: A processing system including at least one processor may request, from an edge server, a plurality of video chunks for a plurality of segments of a video program to fill a video buffer, where the plurality of video chunks is encoded at a startup bitrate comprising a second lowest available bitrate of a plurality of available bitrates in accordance with an adaptive bitrate streaming protocol. The processing system may further receive, from the edge server, the plurality of video chunks, write the plurality of video chunks to the video buffer, and play out the plurality of video chunks from the video buffer when an occupancy level of the video buffer exceeds a threshold. In addition, the processing system may select a next video chunk for a next segment of the video program after the plurality of segments in accordance with a mapping function.

Abstract: A processing system may request, from an edge server, a first video chunk for a first segment and a second video chunk for a second segment of a video program stored in a cache of the edge server, where the first and second video chunks that are requested are encoded at a testing bitrate comprising a second lowest available bitrate in accordance with an adaptive bitrate streaming protocol. The processing system may further receive the first and second video chunks from the edge server via a network link, determine a bandwidth of the network link based upon the testing bitrate, the durations of the first and second video chunks, and an elapsed time to receive the first and second video chunks, and request a third video chunk for a third segment of the video program encoded at a highest available bitrate below the bandwidth of the network link.
