Mobile Video Scene Data Retrieval via Image Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing database solutions provide general information about video content elements, but it is not easily or quickly retrievable and not synchronized with the video content, making it difficult for users to obtain specific information about scene elements during playback.
Innovation Solution
A method and system that allows users to capture images of video content using a mobile device, compare them with a database, and retrieve specific information such as title, date, location, actors, and product placement, while registering the device with a remote server to access supplemental data without disturbing the video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing database solutions provide general information about video content elements, then information availability is improved, but information retrieval speed and synchronization with video content deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-processing video content to extract and annotate scene elements, objects, and their metadata before playback occurs. This allows the database to be pre-populated with structured information about scene elements, enabling rapid retrieval during actual viewing without time-consuming processing delays.
Solution Approach 2:
The system implements feedback mechanisms where user interactions with the video playback interface (such as pausing, seeking, or selecting specific moments) provide feedback signals to the information retrieval system. This feedback enables dynamic adjustment of search queries and data retrieval operations, optimizing the speed and relevance of information delivery based on real-time viewing context.
2Loss of information
If existing database solutions provide general information about video content elements, then information completeness is improved, but ease of retrieving specific scene element information deteriorates
Solution Approach 1:
The system segments the video content into discrete scene elements, objects, and temporal segments, each with unique identifiers and associated metadata. This segmentation allows the database to organize information granularly by scene element rather than providing only general video content information, enabling users to easily retrieve specific details about particular objects or moments.
Solution Approach 2:
The system applies local quality by providing customized information retrieval capabilities tailored to specific scene elements. Instead of uniform general information, the system delivers localized details about particular objects, characters, or moments based on user selections during playback, enhancing the ease of obtaining specific information while maintaining overall information completeness.
3Ease of operation
If users access supplemental data during video playback, then information accessibility is improved, but video playback disruption increases
Solution Approach 1:
The system resolves this contradiction by operating in another dimension - utilizing the temporal and spatial metadata of video frames to enable information retrieval without interrupting the primary video stream. Users can access supplemental data about scene elements through the playback interface without the video itself being disrupted, as the system leverages frame-by-frame analysis and temporal synchronization to provide information alongside rather than interrupting the playback experience.
Data Source
AI summary
Method, system and computer program product for providing additional information to a handheld device (HHD) about a displayed point of interest in video programming displayed on a multimedia display. A image of the video programming captured by a HHD camera can be used at a remote server to identify the video programming by matching it with archived programming. If identified, additional information related to the video programming can be obtained/provided. A region within a particular frame of displayed video programming can be selected at the HHD to access additional information about a point of interest associated with the region. The additional information can be displayed on the HHD or a secondary display, in response to selecting the region to access the additional information from a remote server.
