Wireless Audio Stream Transmission for Multi-Language Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to efficiently transmit multiple audio streams simultaneously to different end points, such as headphones or speakers, while maintaining synchronization with video streams, especially when different family members want to listen to the same video content in different languages.
Innovation Solution
A system and method using a set-top box or information appliance to transmit multiple audio streams over a wireless connection, such as Bluetooth, where each end point receives a distinct audio stream associated with the same video stream, allowing for simultaneous playback of different languages or video content without lag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single audio stream is transmitted to all end points, then hardware requirements are reduced, but different users cannot listen to the same video content in different languages simultaneously
Solution Approach 1:
The patent combines multiple audio stream transmissions into a single wireless communication session between the video device and audio devices. The system transmits multiple distinct audio streams (e.g., different languages) over the same communication channel, allowing multiple users to receive different audio content simultaneously without requiring separate hardware systems for each user.
2Adaptability or versatility
If multiple audio streams are transmitted simultaneously to different end points, then different users can listen in different languages, but system complexity increases
Solution Approach 1:
The audio devices are designed with multi-functionality to handle multiple audio streams within a single communication session. Each audio device can selectively receive and process different audio streams based on user preference, allowing the same hardware to serve multiple functions (different language selections) without increasing overall system complexity.
3Device complexity
If audio streams are transmitted over wireless connection, then hardware requirements are reduced, but synchronization between audio and video may be affected
Solution Approach 1:
The system performs preliminary actions by establishing timing references and synchronization protocols before transmitting audio streams over the wireless connection. The video device and audio devices exchange synchronization information in advance, ensuring that even though audio is transmitted wirelessly, the audio-video synchronization is maintained without lag or delay.

AI summary
A system and method of transmitting respective audio streams to a plurality of end points, such as headphones, earphones, headsets, speakers, etc. is disclosed. Different audio streams are transmitted to each of the plurality of end points. The end points may be arranged to audibly output received audio streams, and so each end point may audibly output a respective different audio stream, i.e. the respective audio streams may be mutually different from each other.
