Multimedia Key Scene Slideshow Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reproducing multimedia content, such as videos, lack efficient ways for users to quickly access and view key scenes, often requiring multiple user inputs for high-speed searching and excluding options for viewing content in both video and slideshow modes.
Innovation Solution
A method and electronic device for displaying and generating multimedia content that allows users to switch between video and slideshow modes, enabling key scenes to be selected and displayed as still images, with text data synchronized for easy navigation and summary information provided for quick understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fast forward and fast rewind functions are used for high-speed search of digital content, then access speed to desired positions is improved, but the number of user inputs required increases and operation complexity worsens
Solution Approach 1:
The system performs preliminary action by automatically generating and storing key scene information (timestamps, scene identifiers, content descriptors) during content ingestion or preprocessing. When a user wants to access key scenes, the system retrieves these pre-generated markers and presents them for selection, eliminating the need for manual fast-forwarding through entire content segments.
Solution Approach 2:
The patent introduces an intermediary layer between the user and the content - a key scene management system that acts as a mediator. This intermediary automatically identifies, extracts, and organizes key scenes from content, then presents them to users as selectable options. The user interacts with this intermediary layer rather than directly manipulating content playback, reducing input complexity while maintaining fast access.
2Manufacturing precision
If traditional video playback mode is used for detailed viewing, then viewing quality is improved, but the ability to quickly navigate and overview key scenes worsens
Solution Approach 1:
The patent applies segmentation by dividing continuous video content into discrete key scene segments with identifiable markers. Each key scene is extracted as a separate entity with metadata (timestamp, duration, content description). Users can selectively access individual segments or groups of segments without viewing the entire continuous content, enabling quick overview of important portions while maintaining the ability to view full-quality video when needed.
Solution Approach 2:
The system implements dynamic mode switching that allows users to transition between different viewing modes (full video playback, key scene slideshow, hybrid modes) based on their current needs. The interface dynamically adjusts between presenting detailed video content and presenting condensed key scene representations, optimizing the balance between viewing quality and navigation efficiency depending on user interaction.
3Loss of time
If key scenes are extracted and displayed as slideshow, then quick access to important content is improved, but the immersive video viewing experience is lost
Solution Approach 1:
The patent implements multi-functionality by designing a system that can operate in multiple modes: full video playback mode for immersive viewing, key scene slideshow mode for quick access and overview, and hybrid modes that combine both approaches. The same key scene extraction infrastructure supports both detailed video viewing and condensed slideshow presentation, allowing users to select the appropriate function based on their current task without sacrificing either viewing quality or access speed.
Data Source
AI summary
Method for displaying multimedia content, electronic device for performing same, and recording medium in which program for executing same is recorded are disclosed. In one embodiment, a method for displaying multimedia content comprises acquiring multimedia content including video data which is reproduced as a video, and slide data including a key scene which is matched with event time point in a reproduction time period of the video data and is displayed in a slideshow manner, acquiring a text data corresponding to the multimedia content, displaying the multimedia content in a first area according to a video mode for reproducing the video data as the video or a slideshow mode for displaying the key scene in the slideshow manner, displaying at least a portion of the text data in a second area; and adjusting the displayed text data according to the displayed multimedia content.
