Display Processing Apparatus for Video Condition Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display systems cannot reproduce display conditions for viewers, as they only record operations performed by deliverers, and require significant recording capacity to synchronize videos across terminals.
Innovation Solution
A display processing apparatus and method that records user operations and their timestamps during video display, allowing for the reproduction of video data and user interactions under the same conditions, using a reception unit, display processing unit, recording unit, and playback control unit to redisplay video data from an external apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If videos are recorded on each terminal apparatus to enable playback under same conditions, then display condition reproduction capability is improved, but recording capacity requirement increases substantially
Solution Approach 1:
The system segments the recording burden by dividing recorded content into two parts: only user operation information (click positions, zoom levels, playback speed) is recorded on the terminal apparatus, while the actual video content is stored externally on video delivery or recording apparatus. This segmentation allows playback condition reproduction without requiring the terminal to store massive video data.
Solution Approach 2:
The patent introduces an intermediary mechanism where operation information is recorded and transmitted to external video delivery/recording apparatus, which then provide the actual video content during playback. This intermediary approach allows the terminal apparatus to reproduce display conditions without directly storing the video content, thereby reducing its recording capacity requirements.
2Ease of manufacture
If only deliverer operations are recorded, then recording complexity is reduced, but viewer flexibility and display condition reproduction are lost
Solution Approach 1:
The system dynamically adapts between live viewing mode (where only operation information is recorded) and playback mode (where the system reproduces both video content and user operations). This dynamic capability allows the same system to serve both deliverers and viewers with different needs, maintaining simplicity while enabling viewer flexibility.
Solution Approach 2:
The patent implements feedback by recording user operations and using them to control video playback automatically. The system feeds back the recorded operation information (click positions, zoom levels, playback speed) to the playback control unit, which reproduces the viewer's previous interactions, thereby providing adaptability and versatility without complex manual configuration.
3Reliability
If massive recording capacity is provided on terminal apparatus, then video synchronization across terminals is improved, but device cost and complexity increase
Solution Approach 1:
The system merges the recording function with external video delivery and recording apparatus rather than requiring each terminal to have independent massive recording capacity. The terminal apparatus combines simple operation recording with external video storage, achieving synchronized playback across multiple terminals without increasing individual device complexity.
Data Source
AI summary
A display apparatus receives video data and plays back the received video data in real time. The display apparatus records history information indicating user operations performed in relation to video display when the video data is being played back and the operation time. Subsequently, to redisplay the video data, the display apparatus acquires appropriate video data from an external apparatus and plays back the video data in real time while reproducing the user operations indicated by history information, according to operation times.
