Method for optimizing media content streaming delivery
The patent US12041300B2 outlines a method and client device for streaming media content, specifically focusing on optimizing the delivery and playback of media chunks to minimize playback stalling. The method begins by establishing an acceptable probability of playback stalling, which is the likelihood that a media chunk will not be delivered in time for playback. The process involves making chunks available for delivery, measuring their delivery times, and storing them in a buffer until they are played. An optimum playback period is calculated based on these delivery times and the predetermined acceptable probability, allowing for adjustments in playback timing to ensure smooth streaming.
Further claims detail the adaptive nature of the playback control. If the actual playback period exceeds the optimum, the method allows for an increased playback rate to reduce buffer content. Conversely, if the playback period is shorter than optimal, the playback rate can be decreased to increase buffer content. The calculation of the optimum period can utilize various statistical methods, including mean and standard deviation of delivery times, or Monte-Carlo simulations. The client device is designed to implement these methods, ensuring efficient media streaming by dynamically adjusting playback rates based on real-time delivery performance.
