Method for optimizing video streaming quality based on reception rate
A recently granted patent (Publication Number: US11925862B2) outlines a method for playing content streamed in a network on a player of a client device. The content is in the form of a sequence of segments available in multiple quality levels, with the player choosing the quality level based on a parameter representing segment reception rate using an Adaptive BitRate (ABR) logic. The method involves receiving a request for a segment at a specific quality level, estimating an optimal response delay for a different quality level, and providing the requested segment after the delay. The model used for estimation is based on a linear regression of the parameter, determined using Ordinary Least Square techniques.
Furthermore, the patent includes details on additional steps such as training the model from a database of examples, verifying the accuracy of the model, and triggering retraining if necessary. The method also involves storing segments in buffers, with the current segment being provided to a second buffer for playback. The patent also covers the implementation of the method in a client device and a computer-readable medium storing the program for executing the method. Overall, the patent focuses on optimizing the streaming experience by dynamically adjusting the quality of segments based on reception rate parameters, enhancing the viewer's experience while consuming content over a network.
