Embodiment Construction

[0036] The invention will now be described with reference to specific examples. However, the present invention is not limited to these examples.

[0037] An example of the present invention presents a method of delivering media content over a network. The media content may be video content (eg, in the form of a video sequence), audio content (eg, in the form of an audio sequence), or the media content may include both audio content and video content (ie, the media content may be multimedia content). The media content includes multiple time segments. Each segment may contain data of a short duration when played (for example, data played for 2 seconds to 15 seconds). The number of data packets per media content segment depends on the duration of the time segment, the encoding bit rate and the size of the individual data packets, and can vary from tens of data packets to thousands of data packets. For example, with a time segment of 10 seconds duration, an encoding bit rate of...

Abstract

In an example of the invention, the delivery of a segment of content is done using an initial congestion window, preferably chosen to give a delivery rate that ensures timely delivery of the segment. However, in case of a higher degree of packet loss, the transfer rate may not be sufficient. Therefore, at any stage during segment delivery, the actual delivery rate is measured and used together with the previous congestion window size, the amount of content segment data still to be delivered, and the remaining delivery time to calculate the updated congestion window. The remainder of the segment is then transmitted using the modified congestion window.

Description

technical field [0001] The present invention relates to methods and apparatus for managing congestion response during transmission of a media sequence over a network. Background technique [0002] There is an increasing demand for delivery of media content (eg, audio content and / or video content) over networks. [0003] One method of delivering a stream of media content over a network is to segment the stream of media content into time segments. Each segment can then be passed across the network in a series of data packets. One class of techniques for segmenting a content stream into time segments is adaptive bitrate delivery. [0004] In adaptive bitrate delivery, media content streams are respectively encoded at multiple bitrates to generate multiple encoded streams. If the media content includes audio content and video content (so that the media stream includes audio streams and video streams), each audio stream and video stream can be encoded at multiple bit rates, re...
