Resource segmentation to improve delivery performance

Abstract

A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.

Description

technical field [0001] Disclosed are embodiments for segmenting resources such as media segments used in live streaming. Background technique [0002] Current Streaming Methods [0003] Current approaches for live and video-on-demand adaptive bitrate streaming rely primarily on Hypertext Transfer Protocol (HTTP) (see eg [HTTP]). In these methods, a client (also known as a user agent or UA) may use HTTP to retrieve a large number of media segments, each media segment containing media samples (ie, audio samples and / or video samples). These media segments enable the client to parse the media segment, decode the media samples, and finally play the media to the client's user according to some format (eg, ISOBMFF). That is, after the media segment has been retrieved, the client can parse the content of the media segment and present it to the user. [0004] Under these current approaches, there are higher layers that provide information about the location of individual media seg...
