Video Output Device Drawing Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video output methods require consecutive calculation and creation of drawing instruction data for each frame, leading to a desire for speeding up the video output process.
Innovation Solution
A video output device and method that store shared first drawing data and generate second drawing data based on differing instruction data for each frame, combining these to produce the final drawing data for efficient output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drawing instruction data is consecutively calculated and created for each video frame, then complete video frames can be generated, but the video output process becomes slow and inefficient
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing common drawing data that appears across multiple video frames. Instead of calculating all drawing data from scratch for each frame, the system prepares shared drawing elements in advance, which are then reused during video generation. This significantly reduces the processing time required for each individual frame while maintaining complete video output quality.
2Manufacturing precision
If all drawing data is calculated for each frame independently, then each frame is complete and accurate, but processing efficiency decreases
Solution Approach 1:
The patent applies segmentation by dividing drawing data into two distinct segments: common drawing data that appears across multiple frames and frame-specific drawing data. The common portion is calculated once and stored, while only the frame-specific portion is recalculated for each frame. This segmentation maintains the accuracy and completeness of each frame while dramatically improving generation efficiency by avoiding redundant calculations.

AI summary
A storage unit storing first drawing data shared in common by at least two video frames among a plurality of video frames. A control unit generating second drawing data based on second drawing instruction data for drawing a portion that differs in drawing data pertaining to the plurality of video frames and generates the drawing data pertaining to the plurality of video frames by combining the first drawing data and the second drawing data. An output unit outputs video based on the drawing data pertaining to the plurality of video frames.
