Personalized Soundtrack via Viewer Preference Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media delivery systems fail to enhance the enjoyment of media content by not accounting for individual viewer preferences in soundtracks, leading to negative experiences due to unappealing music selections.
Innovation Solution
Media receiver devices select replacement songs based on viewer preference data and metadata associated with the media program, ensuring that the soundtrack is personalized to the viewer's tastes by comparing viewer preferences with song attributes and replacing songs from the original soundtrack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standardized soundtrack is used to appeal to as many viewers as possible, then the broad appeal is improved, but the individual viewer satisfaction deteriorates
Solution Approach 1:
The system pre-processes media programs by segmenting soundtracks into individual songs and creating metadata databases with song attributes (genre, tempo, mood, etc.) before playback. This preliminary organization enables rapid comparison and replacement during actual viewing based on user preferences, resolving the contradiction between broad appeal and individual satisfaction.
Solution Approach 2:
The soundtrack is transformed from a static, fixed composition to a dynamic, adaptive sequence where individual songs can be replaced in real-time based on user profile matching against song metadata attributes. This dynamic adjustment allows the system to maintain broad appeal through the original soundtrack structure while adapting to individual viewer preferences through selective song substitution.
2Adaptability or versatility
If song replacement is performed in real-time during playback, then the customization capability is improved, but the processing complexity increases
Solution Approach 1:
The system performs extensive preprocessing by segmenting soundtracks into individual songs, extracting metadata (genre, tempo, mood, artist, album), and organizing replacement pools before playback. This preliminary work stores song attributes in structured databases, enabling simple comparison and matching operations during real-time playback, thus reducing processing complexity while maintaining high customization capability.
Solution Approach 2:
The system introduces metadata as an intermediary layer between the original soundtrack and the replacement songs. Instead of directly comparing and replacing audio files, the system uses metadata attributes (genre, tempo, mood) as mediators to match user preferences with suitable replacement songs, simplifying the complexity of real-time audio processing while enabling sophisticated customization.
3Adaptability or versatility
If the soundtrack is segmented into individual songs for replacement, then the personalization capability is improved, but the structural integrity of the media program deteriorates
Solution Approach 1:
The system segments the continuous soundtrack into discrete song units with defined start and end timestamps, allowing individual songs to be independently replaced while maintaining the overall program structure. This segmentation enables personalization at the song level without disrupting the temporal and structural integrity of the media program, as each replacement song maintains the same duration and timing characteristics.
Solution Approach 2:
The system changes the parameter of song selection while maintaining other structural parameters (duration, timing, synchronization with video) constant. By allowing only the musical content parameter to vary while keeping temporal and structural parameters fixed, the system achieves personalization capability without compromising the structural integrity of the media program.

AI summary
Systems, devices and methods are described to provide a personalized soundtrack by a set top box, media player or other media receiver device. The device obtains viewer preference data that describes the viewer's musical preference. The media program received by the receiver device is associated with metadata describing at least some of the songs in the program soundtrack. The media receiver device compares the viewer preference data and the metadata about the songs already in the soundtrack to select replacement songs that are rendered to the viewer during playback of the media program instead the songs in the audio soundtrack of the media program.
