Content Transmission Apparatus for Dynamic Video Frame Clipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video content distribution systems, such as television broadcasting and video-on-demand, restrict viewers to only predefined image frames, preventing them from viewing videos with specific angles or focusing on particular subjects within the content, like a sport event or concert hall.
Innovation Solution
A content distribution system that allows users to specify a clipping range for video content, enabling the transmission and reproduction of desired image frames by computing and clipping high-resolution video content based on user input, allowing for panning, tilting, and zooming to focus on specific areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is distributed using traditional broadcasting or video-on-demand systems, then the content can be delivered to viewers, but viewers are restricted to only predefined image frames and cannot view videos with specific angles or focus on particular subjects
Solution Approach 1:
The patent segments the video content into multiple predefined image frames (e.g., frame1, frame2, frame3) that can be independently selected and viewed. This segmentation allows viewers to access specific angles or focal points within the original video content without requiring complex real-time processing or multiple camera feeds.
Solution Approach 2:
The system performs preliminary processing to extract and store multiple image frames from the original video content before distribution. These pre-extracted frames are then readily available for immediate selection by viewers, eliminating the need for real-time frame extraction during playback and enabling fast switching between different viewing angles.
2Adaptability or versatility
If multiple image frames are provided for video content, then viewers can select from different angles, but the system complexity increases due to storage and transmission requirements
Solution Approach 1:
The patent creates simplified copies of the original video content in the form of multiple image frames. Instead of transmitting the entire high-resolution video multiple times or performing complex real-time rendering, the system distributes pre-extracted image frame data that can be quickly decoded and displayed, reducing the computational and storage burden on the delivery system.
Solution Approach 2:
The system changes the parameter representation of video content from continuous full-frame video to discrete image frame segments. This parameter transformation allows the same visual information to be conveyed using less data, enabling efficient storage and transmission while maintaining the ability to provide multiple viewing angles.
3Adaptability or versatility
If high-resolution video content is processed in real-time to extract specific image frames, then users can view desired angles, but the processing time and computational resources increase significantly
Solution Approach 1:
The patent performs image frame extraction as a preliminary action during content encoding or pre-processing, rather than during real-time playback. Multiple image frames are extracted and stored in advance, allowing instant retrieval and display when users select different viewing angles, thereby eliminating delays associated with real-time processing.
Solution Approach 2:
The system dynamically switches between pre-extracted image frames based on user selection, providing the flexibility of real-time frame extraction without the computational overhead. The dynamic aspect lies in the ability to quickly transition between different pre-prepared frames rather than generating them on-the-fly.
