- Graphical User Interface for Networked Media Playback Device Management
A graphical user interface displays player icons representing networked wireless speakers to manage media playback across multiple devices and zones.
- Acoustic Image Relocation for Multi-Source Audio Separation
A multi-speaker system moves acoustic images in space to separate audio streams.
- Infrared Audio Channel Encoding via Non-Adjacent Fields
Encoding channel counts in two non-adjacent fields expands capacity beyond 32 channels while maintaining backward compatibility with legacy infrared receivers.
- Spatial Mapping for Media Playback Device Positioning
A spatial mapping system constructs device position maps using localization signals to coordinate playback.
