Video Processing Feedback via Representative Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of online video-hosting services lack clear and accurate feedback on the processing status of their uploaded videos, often relying on misleading progress bars that do not indicate successful decoding or quality issues, leading to misunderstandings about the processing outcome.
Innovation Solution
A video processing server provides feedback by displaying a sequence of processed representative frames, colored or shaded to indicate completion, allowing users to visually track the processing progress and quality through a web page accessible on their browser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a generic progress bar is used to show upload status, then the interface is simple and easy to implement, but the user is misled about the actual processing status and quality of the video
Solution Approach 1:
The patent applies color changes to representative frames to indicate processing status. Each frame is displayed in grayscale, and as frames are successfully processed, they transition to color. This visual transformation provides intuitive feedback about processing progress and quality without requiring complex interface elements, thus resolving the contradiction between interface simplicity and information completeness.
2Loss of information
If detailed processing feedback is provided through multiple visual elements, then the user gets complete information about processing status, but the interface complexity increases
Solution Approach 1:
The patent uses representative frames as visual copies of the video content being processed. Instead of creating complex interface elements or multiple indicator components, the system displays actual video frames that serve as both the processing target and the feedback mechanism. This approach provides comprehensive processing status information while maintaining interface simplicity, as the frames themselves convey all necessary information about processing progress and quality.
3Reliability
If the service processes video into desired formats with quality checks, then the video quality is ensured, but the processing time and computational resources increase
Solution Approach 1:
The patent displays representative frames at selected intervals throughout the video rather than processing and displaying every frame. This partial action approach provides sufficient visual feedback about processing status and quality while reducing the computational burden and processing time. The representative frames are strategically chosen to give users confidence in overall video quality without requiring exhaustive processing of all frames.

AI summary
A system for providing video processing feedback to content providers uploading a video file. As the content provider uploads a video file to the video processing server, the server processes the uploading file and extracts representative video frames from the video file. The video processing server embeds the representative frames into a processing feedback page hosted on a web server in the video processing server. Each representative frame in the feedback page represents a part of the uploading video. The feedback page is accessible through the content provider's browser and the feedback page includes a sequence of representative frames in temporal order. In one embodiment, the representative frames in the feedback page are colored or shaded to indicate whether the video part represented by a particular frame has been processed.
