MULTI-DEVICE LOCALIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240381045 titled 'MULTI-DEVICE LOCALIZATION
The patent application describes a system designed to create a flexible home theater group using various devices, enabling synchronized audio playback through device localization and map data generation.
- The system selects a primary device to determine calibration data for audio playback sequencing.
- The primary device sends calibration data to secondary devices for synchronized playback.
- Each device generates playback audio at a designated time, allowing others to capture and determine relative positions.
- Playback audio may be outside the human hearing range for enhanced synchronization.
Potential Applications: - Home entertainment systems - Audiovisual installations - Multi-device synchronization technology
Problems Solved: - Ensuring synchronized audio playback across multiple devices - Simplifying the setup and calibration process for home theater systems
Benefits: - Enhanced audiovisual experience - Seamless synchronization of audio across devices - Easy setup and calibration process for users
Commercial Applications: Title: "Multi-Device Synchronization Technology for Home Theaters" This technology can be utilized in smart home systems, entertainment venues, and audiovisual production studios to create synchronized audio experiences.
Questions about Multi-Device Synchronization Technology: 1. How does device localization contribute to synchronized audio playback?
- Device localization helps generate map data for accurate positioning of devices in the home theater group.
2. What are the advantages of having playback audio outside the human hearing range?
- By having playback audio outside the human hearing range, the system can ensure precise synchronization without affecting the listening experience.
Original Abstract Submitted
a system configured to create a flexible home theater group using a variety of different devices. to enable the home theater group to generate synchronized audio, the system performs device localization to generate map data, which represents locations of devices in a device map. the map data may include a listening position and/or television, such that the map data is centered on the listening position with the television along a vertical axis. to generate the map data, the system selects a primary device that determines calibration data indicating a sequence when each of the individual devices generates playback audio. the primary device sends the calibration data to secondary devices and each device generates playback audio at a designated time in the sequence, enabling other devices to capture the output audio and determine a relative position of the playback device (for example using angle of arrival and distance information). the playback audio may be outside a human hearing range.
