Problems solved by technology

However, not all receiver devices in the network experience the maximum path delay
Therefore, a receiver device in a lower delay region using segment availability times in the current MPD may experience longer channel acquisition and switching times than necessary because the maximum path delay ratio is in the lower delay region The actual delay experienced by receiver devices is longer

Abstract

Systems, methods, and devices of the various embodiments enable a device to use a modified segment availability time. In various embodiments, a Broadcast Multimedia Service Center (BMSC) server may be enabled to modify a segment availability timeline in which the availability times of the segments. In various embodiments, segment availability time adjustments may be made at a service layer of the receiver device. In various embodiments, segment availability time adjustments may be made by a client application on the receiver device.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 119,353, filed February 23, 2015, entitled "Availability Start Time Adjustment By Device For DASH Over Broadcast," which is hereby incorporated by reference in its entirety This article. Background technique [0003] Currently, Hypertext Transfer Protocol (HTTP) streaming is the most popular method for delivering content on the Internet. For real-time events, the content is made available gradually through segments of fixed duration. This segment availability is along a time axis that indicates when each subsequent segment becomes available at the HTTP server. [0004] Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH) is a standard for implementing HTTP streaming. DASH advertises segment availability in a Media Presentation Description (MPD). The MPD is a segment availability timeline for advertising segments, when segments are available, and ...
