Recording Device Scene Data Chapter Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices face challenges in accurately adding chapters to moving image data, as automatically added chapters may not be placed at the correct positions, and manual allocation is time-consuming, requiring a solution to differentiate between chapters based on scene data and automatically added chapters.
Innovation Solution
A recording device that receives scene data from a server, includes a unit to record and transmit requests for scene data with marks indicating time positions of scene changes, and outputs messages based on response signals, distinguishing between broadcasted and non-broadcasted program data and time elapsed since recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic chapter addition is performed based on broadcast data analysis, then chapter division can be automated without manual intervention, but chapters may be added to incorrect positions where scenes should not be divided
Solution Approach 1:
The patent introduces scene data as an intermediary resource that mediates between automatic chapter addition and accurate scene division. The scene data, created by predetermined operators within a predetermined time after broadcast, serves as a reference that guides the automatic chapter addition process to occur at correct scene boundaries rather than arbitrary positions
Solution Approach 2:
The patent implements preliminary action by creating and storing scene data in advance within a predetermined time after the broadcast program is transmitted. This pre-prepared scene data is then used to guide subsequent chapter addition operations, ensuring that chapters are added at accurate scene positions without requiring real-time manual intervention
2Manufacturing precision
If manual chapter allocation is performed by predetermined operators watching video images, then chapter positions can be accurately determined, but the process becomes time-consuming and requires human intervention
Solution Approach 1:
Predetermined operators perform scene data creation in advance within a predetermined time after broadcast, preparing accurate scene information beforehand. This allows the system to automatically utilize this pre-prepared data for chapter addition, eliminating the need for real-time manual intervention while maintaining high accuracy
Solution Approach 2:
The system enables self-service by automatically acquiring and utilizing scene data created by predetermined operators. The chapter addition process automatically references the pre-created scene data to determine correct chapter positions, eliminating the need for operators to manually intervene during the chapter addition process itself
3Manufacturing precision
If scene data is requested from external servers, then accurate scene data can be obtained when available, but the device cannot receive scene data when the server does not have it or time has elapsed
Solution Approach 1:
The patent implements feedback by having the determining unit check whether scene data was successfully received from the external device. Based on this feedback, the system adaptively switches between using received scene data for accurate chapter addition or falling back to automatic chapter addition without scene data, ensuring the process can always complete regardless of server availability
Solution Approach 2:
The patent prepares for potential failure by having the determining unit ready to handle cases where scene data cannot be received. The system is designed with a fallback mechanism that allows chapter addition to proceed even when external scene data is unavailable, cushioning against the unreliability of external data sources
4Ease of operation
If different message notifications are provided based on whether moving image data is broadcasted program or not, then users can understand why scene data is unavailable, but the system complexity increases
Solution Approach 1:
The patent applies local quality by providing different message notifications tailored to specific situations - one message type for non-broadcasted programs and another for broadcasted programs where scene data is unavailable. This localized approach to messaging improves user understanding by giving context-specific explanations while keeping the complexity contained within the notification system

AI summary
A recording device includes a recording unit that records moving image data in a recording medium, a transmitting unit that transmits a request signal for requesting scene data to an external device, the scene data being information in which a chapter indicating a time position is added for each of scenes in relation to the moving image data recorded in the recording medium, a receiving unit that receives a response signal in response to the request signal from the external device, and an output unit that outputs image data indicating a message when the receiving unit cannot receive the scene data in response to the request signal from the external device. The message is changed according to an elapsed time from a time at which the moving image data is recorded in the recording medium by the recording unit.
