Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast reception devices lack interactivity, requiring users to manually record and identify radio stations, are not user-friendly, and fail to provide personalized experiences or easy music sharing, with limited ability to customize programming based on user preferences.
Innovation Solution
A system that determines the tuned broadcast channel through radiated tuning signals and provides a channel indication for identifying broadcast programming, allowing for real-time customization and personalized playlists based on user preferences, geographic location, and time of broadcast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual station identification and recording is required, then existing broadcast receivers can function, but user convenience and interactivity are significantly reduced
Solution Approach 1:
The broadcast receiver automatically determines the tuned channel by detecting its own radiated tuning signal, eliminating the need for manual station identification. The system serves itself by using its own operational parameters (tuning signal) to identify the broadcast channel, thereby improving ease of operation without requiring complex user input mechanisms
Solution Approach 2:
The system uses feedback from the receiver's own radiated tuning signal to automatically identify the tuned channel. By monitoring the tuning signal that the receiver itself emits, the system obtains real-time information about its current channel without external intervention, enabling automatic channel identification and reducing operational complexity
2Adaptability or versatility
If interactivity services are added to broadcast programming, then user engagement improves, but system complexity and operation time increase
Solution Approach 1:
The broadcast receiver is enhanced with multiple functions: it not only receives broadcast programming but also automatically determines its own tuned channel by detecting radiated tuning signals, and provides interactivity services. This multi-functionality is achieved by integrating existing receiver capabilities with new interactivity features, allowing a single device to perform multiple tasks without requiring separate specialized devices
Solution Approach 2:
The system automatically determines the tuned channel using its own radiated tuning signal without requiring external assistance or complex manual configuration. This self-service approach enables the receiver to autonomously identify the broadcast channel and provide interactivity services, reducing the operational burden on users while maintaining system versatility
3Ease of operation
If real-time interactivity is provided, then user experience improves, but the system becomes more complex and harder to operate
Solution Approach 1:
The system implements real-time interactivity by continuously monitoring the radiated tuning signal to determine the current tuned channel. This feedback mechanism allows the receiver to automatically update channel identification in real-time without requiring manual input, providing immediate and accurate channel information while maintaining ease of use through automation
Solution Approach 2:
The manual mechanical process of identifying and recording stations is replaced by an automated electronic system that detects radiated tuning signals. This substitution of mechanical user input with automated electronic detection enables real-time interactivity while simplifying operation, as the system handles channel identification automatically without requiring user intervention

Function Achieved in This Case
Enables real-time interactivity with broadcast programming, allowing users to create customized playlists and receive personalized content without the need for manual station identification, enhancing user experience and ease of use.
Implementation Method 1
the channel to which a broadcast receiver is tuned is determined from a radiated tuning signal emitted by the broadcast receiver
Implementation Method 2
the channel to which a broadcast receiver is tuned is determined by transmitting a radio frequency channel identification signal and detecting an audio alias of the identification signal

AI summary
A method of and apparatus for allowing a user using a communications device to interact with first media material that is broadcast on a first broadcast channel by a first broadcast media source and second media material that is broadcast on a second broadcast channel by a second broadcast media source, the first media material and the second media material include a first media item and a second media item, respectively, the first media item and the second media item are associated with a first representation of the first media item and a representation of the second media item, respectively, that are received and presented by a broadcast reception device while the broadcast reception device is tuned to a third broadcast channel. The method includes maintaining in a temporary storage an item identifier, the item identifier identifies one of a first media item-related information and a second media item-related information. Additionally, when the broadcast reception device is tuned to the third broadcast channel and presents the first representation of the first media item, the method includes providing the item identifier as a basis for identifying the first media item-related information, the first media item-related information is a basis for a response to an interactivity activation made in reaction to presentation of the first representation of the first media item by the broadcast reception device. When the broadcast reception device is tuned to the third broadcast channel and presents the first representation of the second media item, the method includes providing the item identifier as a basis for identifying the second media item-related information, the second media item-related information is a basis for a response to an interactivity activation made in reaction to presentation of the representation of the second media item by the broadcast reception device.
