Display Device Multi-View Audio Routing Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to output audio for multiple content simultaneously, and audio output is often limited by the type of source and sink devices connected.
Innovation Solution
A display device equipped with a wireless communication interface, a display, and a controller that generates sink sound sources for transmission to multiple sink devices, allowing audio output for each content in a multi-view mode, regardless of device types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple content are displayed simultaneously in multi-view mode, then the quantity of content displayed is improved, but the audio output capability deteriorates (only one audio can be output)
Solution Approach 1:
The patent segments the audio output into separate channels corresponding to different content items. Each content item can have its audio independently routed to sink devices, allowing multiple audio streams to coexist simultaneously. This is achieved by dividing the audio processing path into parallel channels, each handling a specific content item's audio separately.
Solution Approach 2:
The patent introduces a sound source management module as an intermediary between the content display system and sink devices. This intermediary component receives sound sources from multiple content items and intelligently routes them to appropriate sink devices, enabling flexible audio distribution that decouples the display content from the audio output destinations.
2Reliability
If audio output is restricted to specific source-sink device combinations, then the reliability of audio transmission is improved, but the adaptability to different device types deteriorates
Solution Approach 1:
The patent implements a universal audio routing mechanism that can handle multiple source device types (broadcast, cable, satellite, streaming services) and multiple sink device types (built-in speakers, external speakers, headphones, earphones). The sound source management module acts as a universal interface that accepts audio from any source type and distributes it to any sink type, making the system adaptable to diverse device combinations without sacrificing transmission reliability.

AI summary
A display device includes a controller that obtains a plurality of sound sources respectively corresponding to a plurality of content, and generates one or more sink sound sources for transmission to at least one of a plurality of sink devices based on one or more sound sources among the plurality of sound sources. The controller may generate one or more sink sound sources for transmission to at least one sink device corresponding to at least one sink device item selected based on a user input for selecting at least one of a plurality of sink device items included in each of a plurality of sink device lists.
