This publication outlines a system that will enable bandwidth reduction for consumers of audio-visual data, when the consumer is only engaged with a subset of the media stream. Based upon system events from the consuming device, the server modifies the content being sent to the consuming device.

Decoupling of image and audio data to reduce network bandwidth use

It is common for people to stream media content on a device, yet only need a portion of the information. For instance someone may be streaming a live concert or sporting event yet only be actively engaged in the audio; having closed the window it is showing on or similar. Equally it is possible that someone might only be interested in the visual component, having turned off audio. In such cases the bandwidth consumed is a combination of the audio-visual data and not a subset. Ideally a mechanism should exist such that the publishing server is capable of acting intelligently on events sent by the consuming system so that the bandwidth may be used more efficiently. Such a system will now be described.

    We assume that a server is able to send either audio, image or audio + image data to a remote system. The server can change what is sent based on information events from the user system. Media is stored on the server. The server may store the media as a complete file, or associated (decoupled) files. In the former case the media server is assumed capable of actively decoupling the image and audio data for transmission either as pure audio, pure image or a combination of the two. In the latter case it is assumed that the media server is capable of multi-plexing the decoupled files to create a single combined audio-visual stream.

    We assume that the user terminal is capable of connecting to the media server, a...
