Embodiment Construction

[0024] figure 1 is a block diagram illustrating an example collaborative surround sound system 10 formed in accordance with the techniques described in this disclosure. exist figure 1 In the example shown, collaborative surround sound system 10 includes audio source device 12, headend device 14, left front speaker 16A, right front speaker 16B, and mobile devices 18A-18N ("mobile devices 18"). Although shown as including a dedicated front left speaker 16A and a dedicated front right speaker 16B, the techniques may be performed in examples where mobile device 18 also serves as front left, center, and front right speakers. Therefore, the techniques described should not be limited to figure 1 The example collaborative surround sound system 10 shown in the example of . Furthermore, although described below with respect to collaborative surround sound system 10, the techniques of this disclosure may be implemented by any form of sound system that provides a collaborative sound sy...

Abstract

In general, techniques are described for performing constrained dynamic amplitude panning in collaborative sound systems. A headend device comprising one or more processors may perform the techniques. The processors may be configured to identify, for a mobile device participating in a collaborative surround sound system, a specified location of a virtual speaker of the collaborative surround sound system and determine a constraint that impacts playback of audio signals rendered from an audio source by the mobile device. The processors may be further configure to perform dynamic spatial rendering of the audio source with the determined constraint to render audio signals that reduces the impact of the determined constraint during playback of the audio signals by the mobile device.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 61 / 730,911, filed November 28, 2012. technical field [0002] The present invention relates to multi-channel sound systems, and more particularly, to collaborative multi-channel sound systems. Background technique [0003] A typical multi-channel sound system (which may also be referred to as a "multi-channel surround sound system") usually includes an audio / video (AV) receiver and two or more speakers. AV receivers typically include multiple outputs for interfacing with speakers and multiple inputs for receiving audio and / or video signals. Often, the audio and / or video signals are produced by various home theater or audio components, such as televisions, digital video disc (DVD) players, high-definition video players, game systems, record players, compact disc (CD) players, digital media players, set-top boxes (STB), laptops, tablets, and the like. [0004] While AV receivers can process video s...
