Broadcast Media Highlight Recording via OCR Trigger Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in manually browsing through recorded media content to locate specific portions, such as scoring plays in a soccer match, as current DVR systems lack efficient methods for selective recording and playback.
Innovation Solution
A method and system that utilize optical character recognition (OCR) to detect trigger events in broadcast media content, allowing for selective recording and bookmarking of specific segments, enabling users to quickly access desired portions by generating digital bookmarks based on detected changes, such as score updates, and allowing for user-defined trigger events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual browsing is used to locate specific portions of recorded media content, then users can find desired segments, but the process is cumbersome and time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically detecting trigger events (such as score changes in sports) during the broadcast and creating digital bookmarks at those moments. This preliminary bookmarking eliminates the need for manual browsing later, as users can directly jump to pre-identified highlight segments.
Solution Approach 2:
The patent introduces digital bookmarks as an intermediary element between the full recorded content and the user. These bookmarks serve as markers that guide users directly to specific portions of interest, acting as a mediator that simplifies navigation without requiring manual searching through the entire recording.
2Reliability
If the entire broadcast media content is recorded for later viewing, then all content is available, but users must manually browse through unwanted portions to find desired segments
Solution Approach 1:
The system segments the continuous recorded media content into distinct portions marked by digital bookmarks. Each bookmark represents a specific segment of interest (e.g., a scoring play) identified by trigger events. This segmentation allows users to access only relevant portions without having to manually search through the entire continuous recording.
3Measurement precision
If OCR is performed continuously on the entire video stream to detect trigger events, then all trigger events are detected, but the processing complexity and resource consumption increase
Solution Approach 1:
The system applies local quality by performing OCR processing selectively on specific regions of the video stream (such as scoreboards or text overlays) rather than analyzing the entire video content. This region-of-interest approach maintains detection accuracy for trigger events while significantly reducing processing complexity and resource consumption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and efficient viewing of specific media content portions by automatically recording and bookmarking highlight events, reducing the time spent on manual navigation through recorded content.
Implementation Method 1
performing, by the television receiver, OCR on characters present within the video segment
Data Source
AI summary
Systems and methods for selectively recording and bookmarking a portion of broadcast media content include receiving a video stream containing the broadcast media content, determining a video segment of the video stream to be output to a display device, and performing OCR on characters present within the video segment. The systems and methods may further include detecting a trigger event in the OCR of the video segment and creating a digital bookmark corresponding to the detected trigger event. The systems and methods may include generating a recording of a portion of the broadcast media content, whereby the recording begins prior to the trigger event and concludes after the trigger event, and storing the digital bookmark associated with the generated recording.
