Solution Overview
Problem
Conventional video recording and reproducing systems face complexity in associating multiple channels of video data, making it difficult to specify and synchronize data elements recorded at the same timing, leading to cumbersome processing during reproduction.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional video recording systems record multiple channels of video data separately, then each channel can be recorded independently, but it becomes difficult to specify and synchronize data elements that correspond to each other across channels
Solution Approach 1:
The patent combines multiple channels of video data into a single layered data structure where corresponding data elements from different channels are grouped together. This merging approach allows the system to manage multiple channels as an integrated unit, making it easier to specify and synchronize corresponding elements across channels while reducing the complexity of separate channel management.
Solution Approach 2:
The layered data structure serves multiple functions simultaneously: it organizes data elements from different channels, provides synchronization information, and enables easy specification of corresponding elements. This multi-functional structure eliminates the need for separate complex processing systems for each channel, thereby reducing overall device complexity while improving ease of operation.
2Productivity
If video data from multiple channels is recorded separately without association information, then recording processing is simpler, but reproduction and synchronization require complicated processing to identify corresponding data elements
Solution Approach 1:
The patent applies preliminary action by embedding association information and synchronization data into the layered data structure during the recording phase. This pre-organization of data elements with their corresponding relationships established beforehand eliminates the need for complex identification and matching processes during reproduction, thereby improving processing efficiency while reducing reproduction complexity.
3Ease of operation
If additional information is added to each data element to enable association across channels, then data elements can be easily synchronized during reproduction, but the data structure becomes more complex
Solution Approach 1:
The patent implements a nested data structure where additional association information is embedded within the existing layered structure. Corresponding data elements from different channels are grouped together in nested layers, with synchronization information integrated into the structure itself. This nesting approach enables easy synchronization through the hierarchical organization while managing structural complexity through systematic arrangement.
4Loss of time
If multiple channels of video data are recorded with association information, then corresponding data elements can be specified easily during reproduction, but the recording and data management system becomes more complex
Solution Approach 1:
The system performs preliminary organization of data elements into layered structures with embedded association information during recording. This pre-establishment of corresponding relationships and synchronization data eliminates the need for time-consuming identification and matching processes during reproduction, thereby reducing the time required to specify corresponding data elements while managing recording system complexity through systematic data organization.
