DVD Recording Apparatus Cell-by-Cell Editing Navigation Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional DVD recorders require users to reproduce all video titles when only a part of the recorded image is desired, making image reproduction inflexible and disadvantageous.
Innovation Solution
A DVD recording apparatus and method that allows cell-by-cell editing, enabling users to selectively record and reproduce images by temporarily storing cell information and creating navigation data, which is displayed on a GUI for user selection and storage on the DVD.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all video titles are reproduced in a typical DVD recorder, then complete image reproduction is achieved, but reproduction flexibility is reduced and unnecessary titles are played
Solution Approach 1:
The patent segments the recorded image into multiple cells, where each cell represents a discrete video title or portion of content. This segmentation enables independent selection and reproduction of individual cells, allowing users to reproduce only desired portions rather than all titles, thereby improving reproduction flexibility and reducing unnecessary playback time.
2Adaptability or versatility
If cell-by-cell editing functionality is added to allow selective reproduction, then reproduction flexibility is improved, but device complexity increases
Solution Approach 1:
The patent performs preliminary actions by automatically designating cell starting points during the recording process and pre-generating navigation data that maps cell information to reproduction commands. This preliminary structuring of data during recording eliminates the need for complex real-time processing during reproduction, allowing selective playback without significantly increasing device complexity.
3Measurement precision
If manual cell starting point designation is enabled, then precise cell control is achieved, but user operation time increases
Solution Approach 1:
The patent implements a dynamic system that allows cell starting points to be designated either manually or automatically based on user preference and operational context. The system adapts between these two modes, providing precise manual control when needed while offering automatic designation for faster operation, thereby balancing precision requirements against time constraints.
