Tag List Synchronization via Time Difference Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recording/reading apparatuses lack accurate and user-friendly methods for generating and managing chapter marks and tags in content, leading to inconsistencies and user experience issues when setting chapters or tags during playback.
Innovation Solution
The apparatus generates tag association information that designates specific zones of content using start and end points, allowing for accurate positioning and external construction of tag lists, enabling multiple users to utilize the information and correct time differences for synchronized playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic chapter generating means is used to automatically generate chapters, then chapter generation is automated, but the accuracy and user-friendliness of chapter and tag management deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically generating candidate chapters and tag lists before user review, then allows users to refine and correct these preliminary results. This combines automation efficiency with user precision by having the system do the initial work and the user make final adjustments.
Solution Approach 2:
The system introduces an intermediary review and correction process between automatic generation and final chapter/tag establishment. Users act as intermediaries who can adjust automatically generated chapters and tags, bridging the gap between automated efficiency and manual accuracy.
2Ease of operation
If users manually set chapters during playback by operating remote controller keys, then user control is enabled, but time consumption and operational complexity increases
Solution Approach 1:
The system performs preliminary chapter generation and tag list creation automatically before playback, so users don't need to manually set chapters during playback. Users only need to review and make minor adjustments if needed, significantly reducing the time and effort required.
Solution Approach 2:
The system serves itself by automatically generating chapters and tag lists without requiring user intervention during playback. The automated system handles the time-consuming task of chapter creation, freeing users from manual operations.
3Adaptability or versatility
If tag lists are constructed externally, then multiple users can utilize the information, but synchronization and consistency across users becomes difficult
Solution Approach 1:
The system creates tag lists that serve multiple functions: they can be used individually by each user based on their preferences, yet remain consistent across the system. The same tag list structure can be universally applied while allowing user-specific customizations.
Solution Approach 2:
The system allows different parts of the tag list to have different qualities - some tags remain consistent across all users for synchronization, while other tags can be customized locally by individual users based on their preferences, achieving both consistency and adaptability.
Data Source
AI summary
According to one embodiment, there is provided a control block including a read control processor for reading designated content, a time information processor for processing time information. A controller returns, to a user terminal, a response signal, and information indicating a second absolute time point when an operation is executed in response to a request signal generated by the user terminal at a first absolute time point. The controller stores time difference information indicating a time difference between the first and the second absolute time points. When responding to a further request signal sent from the requester via the network, the controller sets, as tag time information, time information obtained by correcting, using the time difference information, a current relative time period for which the designated content is read.
