Abstract

In general, techniques are described for image generation for a collaborative sound system. A headend device comprising a processor may perform these techniques. The processor may be configured to determine a location of a mobile device participating in a collaborative surround sound system as a speaker of a plurality of speakers of the collaborative surround sound system. The processor may further be configured to generate an image that depicts the location of the mobile device that is participating in the collaborative surround sound system relative to the plurality of other speakers of the collaborative surround sound system.
