Signal Processing Device Metadata Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal processing devices face difficulties in efficiently searching and correcting inappropriate video or audio signals distributed or recorded due to erroneous switching operations, leading to inefficiencies in editing and collaboration.
Innovation Solution
A signal processing device that records metadata associated with switching operations, allowing for enhanced search and correction of inappropriate switches by generating a playlist that includes metadata, thereby improving user convenience and collaboration in post-distribution editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If conventional switching operations are performed without metadata recording, then the device complexity is reduced, but the ability to search and correct inappropriate switching operations deteriorates
Solution Approach 1:
The system performs preliminary action by recording metadata at the time of switching operations. The metadata includes switching timing, selected signal information, and evaluation results, which are stored in advance to enable later detection and correction of inappropriate switching without adding complex real-time detection mechanisms.
Solution Approach 2:
Metadata serves as an intermediary between the switching operation and the evaluation process. Instead of directly monitoring and detecting inappropriate switching in real-time, the system uses metadata as a mediator to record and store switching information, which can then be evaluated later to identify issues.
2Productivity
If metadata is recorded for every switching operation, then the search performance for inappropriate switching is improved, but the loss of time for processing and managing metadata increases
Solution Approach 1:
The system extracts only the essential metadata needed for switching evaluation, such as switching timing, selected signal information, and basic evaluation results. By taking out only the necessary information rather than recording all possible data, the system maintains high search performance while minimizing processing time and storage requirements.
Solution Approach 2:
The metadata structure is designed to be self-service oriented, with predefined fields and formats that automatically capture switching information. This reduces the manual processing time required for metadata management, as the system automatically generates and organizes the data without requiring extensive manual intervention.
3Ease of operation
If an independent meta-input unit is provided separate from the switch input unit, then the ease of operation for metadata input is improved, but the device complexity increases
Solution Approach 1:
The input system is segmented into two independent units: the switch input unit for signal selection and the meta-input unit for metadata input. This segmentation allows each unit to be optimized for its specific function, improving ease of operation by reducing interference between different input operations while maintaining manageable device complexity through functional separation.

AI summary
In the present signal processing device, a recording unit is configured to record an inputted signal into a recording medium. A switch input unit is configured to input signal selection information for selecting any one of a plurality of signals. A meta-input unit is provided independently from the switch input unit. The meta-input unit is configured to input metadata. A switch list managing unit is configured to associate the signal selection information and the metadata and manage the signal selection information and the metadata as a switch metadata information every time the signal selection information is inputted into the switch input unit. A playlist recording unit is configured to determine a reproduction duration of each clip and generate a playlist including the metadata based on the switch metadata information. The playlist recording unit is configured to output the playlist to the recording medium.
