Abstract

Official abstract text for this publication.

A client/receiver downloads data over a network path between a source and the receiver coupled by the network path and stores the media data in a presentation buffer of the receiver and from there it is consumed by a presentation element. The receiver monitors a presentation buffer fill level that represents what portion of the presentation buffer contains media data not yet consumed by a presentation element. The receiver makes requests for additional data to download. If the fill level is above a high fill threshold, the receiver does not make further requests and eventually the fill level goes down. If the fill level is below a low fill threshold, the receiver restarts the downloading and updates the fill level as media data is consumed by the presentation element. The fill level might be measured in units of memory storage capacity and/or units of presentation time.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of controlling data downloading over a network path between a source and a receiver coupled by the network path, the method comprising: downloading media data from the source, wherein downloading occurs over a number of TCP connections determined as a function of a bandwidth-delay product, the bandwidth-delay product including a product of an estimated round-trip time (ERTT) and a receive rate, the ERTT including a difference in time between transmi…
