Multimedia Summary Generation for News Broadcasts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in efficiently browsing and selecting video content due to the vast amount of available video material and limited time, as traditional search and retrieval techniques require explicit search topics, which may not align with casual viewing habits like channel-surfing or background monitoring.
Innovation Solution
A system and method for generating a multimedia summary of video, audio, and text portions of a news broadcast, allowing users to automatically create a compact representation suitable for various devices, customizable based on user preferences and constraints, without the need for explicit keywords, by filtering key elements based on importance, user profiles, and device/network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional search and retrieval techniques are used, then users can find specific content by keywords, but users must have explicit search topics which does not align with casual viewing habits
Solution Approach 1:
The system automatically generates multimedia summaries without requiring user input of search keywords. The summarization system performs self-service by autonomously analyzing video content, extracting key elements, and generating summaries that users can directly consume, eliminating the need for explicit search tasks
Solution Approach 2:
The system performs preliminary summarization of video content before users arrive. By pre-processing the video material and creating compact representations in advance, the system prepares content that users can immediately browse and select from, rather than requiring users to initiate searches
2Loss of information
If the complete video is provided, then users have access to all content, but users cannot efficiently decide what to view due to vast amount of content
Solution Approach 1:
The system extracts key elements from the complete video content, such as important scenes, audio highlights, and text captions. By taking out only the essential portions and presenting them in a compressed summary format, users can quickly assess content relevance without viewing the entire video, saving significant browsing time
Solution Approach 2:
The video content is segmented into discrete key elements and scenes that can be independently evaluated. The summarization system divides the continuous video stream into manageable segments with associated metadata, allowing users to efficiently scan and select interesting portions without being overwhelmed by the continuous flow of complete video content
3Adaptability or versatility
If multimedia summaries are generated for all devices, then compatibility is improved, but bandwidth consumption increases for high-resolution devices
Solution Approach 1:
The system dynamically adjusts the quality and resolution of multimedia summaries based on the requesting device's capabilities. By making the summary quality adaptive rather than static, the system optimizes bandwidth consumption for each device type while maintaining compatibility across the full range of devices from mobile phones to personal computers
Solution Approach 2:
Different quality levels of summaries are provided for different devices. Instead of using a uniform high-quality format for all devices, the system applies local quality adjustments where high-resolution formats are used only for capable devices like PCs, while lower-resolution formats are used for bandwidth-constrained devices like mobile phones, optimizing overall network resource utilization
Data Source
AI summary
A system facilitates and enhances review of one or more multimedia input streams that includes some combination of video, audio and text information, generating a multimedia summary, thereby enabling a user to better browse and/or decide on viewing the multimedia input streams in their entirety. The multimedia summary is constructed automatically, based in part on system specifications, user specifications and network and device constraints. In a particular application of the invention, the input multimedia streams represent news broadcasts (e.g., television news program, video vault footage). In such a particular application, the invention can enable the user to automatically receive a summary of the news stream in accordance with previously provided user preferences and in accordance with prevailing network and user device constraints.
