Problems solved by technology

For example, it might be computationally complex to transcode a media stream to a lower bitrate, or a lower bitrate might just not be supported by the streaming source
In addition, when certain calculations (such as fingerprinting or watermarking algorithms) are applied to content, these calculations may require certain minimum quality

Embodiment Construction

[0067] The following embodiments relate to methods and controllers for enabling non-contiguous streaming of media streams from a streaming source to a sink. refer to Figure 1 to Figure 3 provides a general explanation, while Figure 4A to Figure 8 show specific examples and Figure 9 An exemplary data processing system for use in implementing any of the described embodiments is shown. It will be appreciated that no example should be construed as representing a limitation of the invention.

[0068] figure 1 Streaming source 120 is illustrated streaming a media stream to receiver 100 via a network. exist figure 1 In the example shown, the network is shown to include a core network 200 (shown symbolically as a cloud), an ingress network 202 (through which stream sources 120 connect to core network 200) and an egress network 204 (with which sink 100 utilizes egress The network 204 is connected to the core network 200) (they are shown symbolically as lines connectin...

Abstract

A method and controller are provided for performing a non-contiguous streaming of a media stream. Such non-contiguous streaming comprises transmitting a selected portion of the media stream to the receiver while omitting transmitting at least an immediately adjacent portion of the media stream so as to enable uninterrupted play-out of the selected portion by the receiver after a pre-determined play-out delay. Such non-contiguous streaming may be advantageously used when the content bitrate exceeds the available network bandwidth. Namely, instead of streaming all of the media stream, only one or more selected and non- adjacent portions thereof are streamed, while omitting transmitting one or more intermediate portions. Effectively, the available network bandwidth may be allocated for transmitting only selected portions of the media stream to enable said portions each to be played-out uninterruptedly by the receiver after a pre-determined play-out delay and at the original content bitrate. Buffer underruns at the receiver may thereby be prevented.

Description

technical field [0001] The present invention relates to a method and controller for streaming a media stream to a receiver via a network. The invention also relates to streaming sources and sinks. The invention also relates to a computer program product comprising instructions for causing a processor system to perform the method. Background technique [0002] Media content, such as video content and audio content, is commonly delivered to users in digital form. If the media content has a temporal aspect, and in particular the media content is associated with a timeline indicating how the media content should play out over time, such a digital form is often referred to as a media stream. The media stream may be delivered to the user's receiver via a (media distribution) network. In particular, the media stream can be streamed to the receiver, which allows the receiver to start playing out the media stream before receiving the complete media stream. [0003] Examples of me...
