AI Technical Summary

Problems solved by technology

Long delivery delays (typically seconds or more) caused by unstable last mile bandwidth
Delivery delays can leave the video player software with no content to play and cause the video player software to stop playback of the video content until the delivery restarts and the buffer is sufficiently filled

Abstract

A method and apparatus for creating universal adaptive bit rate streams using a generic container format to store audio, video, and supplemental data that allows seamless trans-containerization from one adaptive streaming format to another.

Description

Technical field [0001] The present invention generally relates to media content delivery. Background technique [0002] The methods described in this section can be implemented, but these methods are not necessarily methods that have been previously designed or implemented. Therefore, unless otherwise indicated herein, the methods described in this section are not prior art to the claims in this application and are not allowed to become prior art through inclusion in this section. [0003] Over the years, the delivery of video content on the Internet has developed. The initial application of video transmission from content server to client computer is limited by technology and bandwidth capacity. The size of the video file must be significantly reduced to accommodate the low bandwidth of the telephone line. The low-resolution video content must be downloaded to the client computer as a whole before the video file can be played to the user. This is due to file system limitations...
