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: 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.
