Content-Based TV Navigation Using Real-Time Pictorial Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation methods for live TV/video broadcasts rely on linear and fixed forward/backward buttons, lacking intelligent content-based indexing for non-linear navigation, which limits user control and efficiency.
Innovation Solution
Implementing real-time content-based indexing techniques that generate a pictorial index of live video programs, allowing users to non-linearly jump to points of interest using images and text, with the index being extracted and processed in real-time for immediate navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If forward and backward buttons are used for navigation, then users can jump backward or forward by a predetermined fixed amount, but the navigation is linear and lacks intelligence, reducing user control and efficiency
Solution Approach 1:
The video program is divided into multiple scenes, and a pictorial index is generated showing thumbnails of different scenes. Users can select specific scenes from the index to navigate to, transforming continuous video navigation into discrete scene selection. This segmentation enables intelligent content-based navigation while maintaining ease of operation.
Solution Approach 2:
A pictorial index serving as an intermediary between the user and the video content is introduced. The index contains extracted images and text that represent different scenes, allowing users to navigate content without directly interacting with the video stream. This intermediary provides content awareness while enabling efficient navigation.
2Ease of operation
If a pictorial index is extracted from the entire program, then content-based navigation is enabled, but for live broadcasts the processing time increases and navigation readiness is delayed
Solution Approach 1:
The system performs preliminary extraction of images and text from the live video program as it is being received, generating the pictorial index in real-time before the user needs to navigate. This preliminary action ensures the index is ready immediately for navigation without delaying user interaction.
Solution Approach 2:
The index extraction process continues continuously as the live video program is being received, rather than processing the entire program at once after recording. This continuous extraction maintains navigation readiness throughout the broadcast without interrupting the live stream or causing delays.
3Productivity
If fixed forward/backward button jumps are used, then the navigation mechanism is simple, but user control is limited and efficiency is reduced
Solution Approach 1:
The system automatically extracts images and text from the video program to generate the pictorial index without requiring user intervention. The indexing process serves itself by utilizing the video content's own visual and textual elements, eliminating the need for manual bookmarking or external indexing tools.
Solution Approach 2:
The navigation system transitions from fixed temporal jumps (forward/backward by fixed amounts) to content-based jumps (by selecting specific scenes). This parameter change from time-based to content-based navigation dramatically improves navigation speed and user control while the automatic extraction keeps the added complexity manageable.
Data Source
AI summary
A system, method and computer-readable medium are presented for providing real-time content-based navigation of live video programming. The video programming is received and a searchable database is generated. The method aspect of the invention comprises receiving a live video program, generating an index to the received live video program by extracting images and/or text from the video program, recording the live video program, presenting at least a portion of data associated with the generated index to a user, receiving user input regarding a search to a portion of the recorded video program to which the user desires to navigate and playing back the recorded video program starting at the searched portion identified by the user input. The search may be of an image and/or text portion of the presentation.
