Video Processing System for Variable Frame Rate Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current movie production and exhibition technologies require significant costs for equipment, storage, and bandwidth to support high frame rates, and existing display devices cannot seamlessly handle videos shot at non-constant frame rates, limiting the cost-effective exhibition of high-quality video content.
Innovation Solution
A method for video processing that receives input videos with varying frame rates and metadata to output a constant target frame rate, allowing real-time processing and transmission of videos, enabling cost savings and compatibility with existing display devices by converting non-constant frame rate videos to a constant high frame rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high frame rate video exhibition is implemented using traditional methods, then video quality and smoothness are improved, but equipment costs, storage costs, and bandwidth costs increase significantly
Solution Approach 1:
The patent changes the frame rate parameter from constant to variable, allowing different sections of the video to have different frame rates. This enables high frame rate playback only where needed (improving video quality) while reducing overall data volume and costs
Solution Approach 2:
The video is divided into multiple sections with different frame rates. By segmenting the video content, the system can apply high frame rates selectively to specific sections rather than the entire video, reducing overall storage and bandwidth requirements while maintaining quality where needed
2Quantity of substance
If videos are shot at non-constant frame rates to reduce costs, then storage and bandwidth costs are reduced, but existing display devices cannot seamlessly handle the variable frame rates
Solution Approach 1:
The patent introduces a playback device as an intermediary that converts variable frame rate video into constant frame rate output. This mediator handles the frame rate conversion seamlessly, making variable frame rate videos compatible with existing display devices without requiring upgrades
Solution Approach 2:
The playback device dynamically changes the frame rate parameter from variable (input) to constant (output). This parameter transformation enables compatibility with traditional display devices while preserving the cost benefits of variable frame rate encoding
3Reliability
If constant high frame rate is used throughout the entire video, then smooth visual experience is maintained, but storage space and bandwidth requirements increase significantly
Solution Approach 1:
Different sections of the video are assigned different frame rates based on their specific requirements. Action-intensive sections use higher frame rates for smooth visuals, while static sections use lower frame rates to reduce data volume, achieving local optimization of both quality and efficiency
