Embodiment Construction

[0016] Before at least one embodiment of the present invention is set forth in detail, it is to be understood that the present invention is not limited in application to the specific structures and arrangements of components described in the following description or shown in the accompanying drawings. The present invention is applicable to other embodiments or embodiments practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

[0017] The present invention aims to overcome the deficiencies of prior art adaptive video streaming systems by ensuring maximum bitrate playback of adaptive streams while minimizing player resolution variation. This goal is achieved through the following steps:

[0018] 1. Form a network burst and predict the next resolution, thus ensuring high-quality video with minimal resolution changes.

[0019] 2. Maximi...

Abstract

An adaptive video streaming system comprises a computer network (14) comprising a data source, a video player (120), a session controller (130) configured to use in parallel a variable number of streams in order to maximize download throughput from said data source to said video player (120), and an adaptive streaming optimizer (210) connected between said data source and said video player (120), the adaptive streaming optimizer (210) configured to predict the next resolution to be requested by the player (120) and determine which fragments to download accordingly.

Description

technical field [0001] The present invention relates to the field of computer networks and, more particularly, to improving the display of adaptive video streams in such networks. Background technique [0002] A common problem encountered by many web users is poor adaptive video streaming viewing experience. Two major challenges that hurt the viewing experience of end users are watching intermediate video resolutions and frequent resolution changes. [0003] The player attempts to address these issues by capturing a cache of data and measuring the download data rate to make decisions about resolution changes. Changing network / communication link conditions may cause network bursts. This behavior can cause rapid resolution changes. These changes degrade the overall user experience and should be avoided. [0004] There is a need for a method to ensure maximum bit rate playback of adaptive streams while minimizing player resolution changes for better viewing experience. Co...
