Broadcast Device Unicast to Party Mode via BMS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most end devices on the market, such as mobile phones and laptops, only support traditional unicast functions and do not support party mode, limiting the ability of Bluetooth speakers that only support unicast functions to implement party mode.
Innovation Solution
The integration of a unicast data-receiving function and a Broadcast Media Sender (BMS) function in a broadcast device allows it to receive audio data via a unicast link and broadcast it to playback devices, enabling party mode functionality even with devices that only support unicast functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If end devices use traditional unicast functions only, then device compatibility is maintained, but party mode functionality cannot be achieved
Solution Approach 1:
The patent merges the unicast data receiving function and the broadcast media sender function into a single broadcast device. This allows the device to receive audio data via unicast link from end devices and simultaneously broadcast it to multiple playback devices, enabling party mode functionality without requiring end devices to have complex broadcast capabilities.
Solution Approach 2:
The broadcast device acts as an intermediary between end devices (mobile phones, laptops) and playback devices (speakers). It receives unicast audio data from end devices, converts it to broadcast format, and transmits to multiple playback devices, thereby enabling party mode for devices that only support traditional unicast functions.
2Productivity
If end devices support only unicast functions, then device simplicity is maintained, but synchronous audio playback with multiple devices is limited
Solution Approach 1:
The broadcast device combines unicast receiving and broadcast sending capabilities in one unit, enabling synchronous audio playback across multiple devices while keeping end devices simple and compatible with traditional unicast protocols.
3Adaptability or versatility
If Bluetooth speakers only support unicast functions, then device complexity is reduced, but party mode implementation is prevented
Solution Approach 1:
The broadcast device serves as a protocol conversion intermediary, receiving unicast audio streams from end devices and redistributing them via broadcast protocol to multiple speakers, thereby enabling party mode without requiring end devices or speakers to support multiple protocols natively.
Data Source
AI summary
An audio playback method and device are provided. The audio playback method includes a broadcast device. The broadcast device obtains the audio-to-be-played from a source device via a unicast link. When indicated by the source device to apply a party mode to play the audio-to-be-played, the broadcast device serves as a broadcast media sender and broadcasts the audio-to-be-played to at least one playback device, so as to play the audio-to-be-played through the at least one playback device. This makes a device that only supports traditional unicast functions can also apply the party mode to play the audio-to-be-played.
