Smartphone Bluetooth Audio Receiver for Set-Top Box Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems do not effectively allow users to receive and listen to audio from audiovisual content on a smartphone connected via Bluetooth to a device transmitting audio, while simultaneously receiving video on a different display device, without requiring specialized Bluetooth headphones and without disrupting the audio experience with phone calls or other notifications.
Innovation Solution
A smartphone with a Bluetooth module can pair with a set-top box or other devices to receive and process audiovisual content, enabling audio to be sent to the smartphone for listening, with features like pausing for phone calls, adjusting sound levels, and displaying information related to the content, using the smartphone's computing power for additional functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth headphones are used to receive audio from a set-top box, then audio can be transmitted wirelessly, but specialized Bluetooth headphones are required and battery life is limited
Solution Approach 1:
The smartphone serves multiple functions: it acts as a Bluetooth audio receiver for television content, a power bank to extend headphone battery life, and a control interface for audio settings. This multi-functionality eliminates the need for specialized Bluetooth headphones while providing comprehensive audio reception capability.
Solution Approach 2:
The system uses the smartphone's existing battery and processing capabilities to serve the audio reception need. The smartphone's battery powers the Bluetooth headphones when needed, and its processor handles audio streaming and control, making the system self-sufficient without requiring dedicated hardware.
2Duration of action of moving object
If Bluetooth headphones are used for audio reception, then wireless audio transmission is achieved, but battery life of the headphones is limited
Solution Approach 1:
The smartphone serves as a portable power source for the Bluetooth headphones. When the headphones' battery is low or depleted, the smartphone charges them directly, enabling continuous audio listening without being constrained by the headphones' limited battery life.
Solution Approach 2:
The smartphone pre-charges the Bluetooth headphones before audio playback begins or during idle periods. This preliminary charging action ensures that the headphones are ready for extended use and can maintain audio playback for longer durations.
3Adaptability or versatility
If a smartphone receives audio via Bluetooth from a set-top box, then existing earbuds can be used, but phone calls or notifications may disrupt the audio experience
Solution Approach 1:
The smartphone acts as an intermediary device between the set-top box and the earbuds. It manages Bluetooth connections, prioritizes audio streams, and controls when phone calls or notifications interrupt audio playback, providing a more reliable and controlled audio experience.
Solution Approach 2:
The system dynamically manages Bluetooth connections and audio prioritization. The smartphone can switch between different audio sources, adjust connection priorities, and control notification behaviors based on the current audio playback state, ensuring continuous and reliable audio delivery.

AI summary
Systems and methods are provided for allowing a user with a Smartphone to pair the Smartphone with another Bluetooth device to receive audio that is played to the user over headphones or through speakers on the Smartphone. Further, an audio processing module is used to modify the audio presented to the user, extract closed captioning text to be displayed to the user, find information relevant to the audio to be displayed to the user, and pause audio content sent to the Smartphone when phone calls or other Smartphone interruptions occur.
