Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for modifying one or more parameters of a data streaming bitrate selection algorithm based on machine learning. An example embodiment operates by training and operating a first machine learning model to predict a sustainable network bandwidth. A second machine learning model is trained to receive the sustainable network bandwidth and predict a likelihood that this network bandwidth will not empty a data buffer of streaming data. A bitrate is selected based on the likelihood being below a threshold percentage, such as 50%.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for performing adaptive audio bitrate selection. An example embodiment operates by receiving a data streaming request. The embodiment then streams data at a first audio bitrate. The embodiment then determines whether there is a streaming discontinuity associated with the data. The embodiment then determines, in response to the determination that there is a streaming discontinuity, whether a network condition satisfies one or more conditions based on one or more streaming parameters. The embodiment then, in response to the determination that the network condition satisfies the one or more conditions, adjusts the first audio bitrate to a second audio bitrate during the streaming discontinuity. The embodiment then continues to stream the data, subsequent to the streaming discontinuity, at the second audio bitrate to complete the data streaming request.
