Directional Audio Transmission to Broadcast Devices - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240292147 titled 'Directional Audio Transmission to Broadcast Devices

Simplified Explanation: The patent application describes mechanisms for directional audio transmission to broadcast devices based on the spatial direction of the user's audio message.

• **Key Features and Innovation:**

   - Control device estimates the spatial direction of the user's audio message.
   - Selects a set of broadcast devices based on the estimated spatial direction.
   - Initiates transmission of the audio message to the selected broadcast devices.

Potential Applications: This technology can be used in conference calls, public address systems, and smart home devices to enhance audio transmission based on user direction.

Problems Solved: This technology addresses the challenge of directing audio messages to specific areas or devices based on the user's spatial direction, improving the overall audio experience.

Benefits: - Enhanced audio transmission based on user direction. - Improved clarity and focus of audio messages. - Efficient use of broadcast devices for targeted audio delivery.

Commercial Applications: The technology can be applied in smart speakers, virtual assistants, conference systems, and public announcement systems to optimize audio transmission based on user direction, potentially improving user experience and system efficiency.

Questions about Directional Audio Transmission: 1. How does directional audio transmission improve user experience in smart home devices? 2. What are the potential cost-saving benefits of using directional audio transmission in public address systems?

Frequently Updated Research: Stay updated on advancements in spatial audio technology, user interaction with smart devices, and audio transmission algorithms to enhance the effectiveness of directional audio transmission systems.

Original Abstract Submitted

there is provided mechanisms for directional audio transmission to at least one broadcast device. a method is performed by a control device. the method comprises obtaining an indication that an audio message as uttered by a user is recorded and is to be transmitted to at least one broadcast device. the method comprises estimating in which spatial direction the user uttered the audio message. the method comprises selecting, as a function of the estimated spatial direction, a set of broadcast devices for playing out the audio message. the method comprises initiating transmission of the audio message to the selected set of broadcast devices. the control device thereby performing the directional audio transmission to the at least one broadcast device.
