Abstract: A device for retrieving media data includes one or more processors configured to determine, for a segment of a representation of media data, whether to use segment index (SIDX) information of the segment, and in response to determining not to use the SIDX information, retrieve media data of the segment without using the SIDX information of the segment. The processors may determine whether to retrieve the SIDX information based on a determination of whether the segment includes SIDX information and/or based on a playback duration of the segment.

Abstract: In overview, the various embodiments provide methods implemented by a processor executing a DASH client on a receiver device for determining when, in view of a change in the receiver device's resources (e.g., bandwidth, battery power, etc.), to cancel or abandon downloading the current segment at the current representation and restart download of the current segment at a different representation to meet one or more performance objectives and/or optimizations related to the change in the receiver device's resources. In various embodiments, the receiver device processor may perform a cost-benefit analysis to determine whether switching representations during the ongoing download of the current segment will benefit the performance of the receiver device, and the receiver device processor may switch representations in response to determining that switching representations would improve the performance of the receiver device.

Abstract: A method for altering bandwidth consumption when receiving content in a user device includes determining a first user device status where the first user device status indicates whether content, which is being accessed by a content-rendering application, is viewable on a display of the user device, based on the first user device status, selecting one of a plurality of available alternative content segments, and receiving the selected content segment.

Abstract: Methods, devices, systems, and non-transitory computer-readable storage media for improving the reception of data at a computing device by proactively utilizing new TCP connections in response to identifying that TCP connections have stalled. In an embodiment, a processor of the computing device may perform operations including monitoring a status of requests via a plurality of TCP connections, identifying a stalled TCP connection having a missing request based on the monitoring, wherein the stalled TCP connection is configured to utilize a first network interface and access a first data source, evaluating other TCP connections to determine whether the other TCP connections stall using the first network interface or when accessing the first data source; identifying a second network interface and a second data source based on the evaluating, and reissuing the missing request with a new TCP connection configured to use the second network interface and access the second data source.
