Reproduction Control Apparatus Terminal End Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reproducing time series data, such as moving images and audio, fail to quickly and reliably check the vicinity of the terminal end of a clip, making it difficult for users to verify recording completeness and decide on subsequent recording tasks.
Innovation Solution
A reproduction control apparatus and method that allows for quick and reliable reproduction of the terminal end of time series data by jumping the reproduction position in ten-second units during the REC review function, which can reproduce from the beginning or 4 seconds before the end of a clip, ensuring efficient checking of recently recorded content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If jump reproduction is performed to enable fast forward/fast rewind, then reproduction speed is improved, but the ability to check the terminal end of recorded content deteriorates
Solution Approach 1:
The system automatically positions the reproduction playback to the terminal end section of the recorded content before the user initiates playback. This preliminary positioning ensures that when the user presses the playback button, the terminal end is already displayed, allowing immediate verification of recorded content without requiring manual navigation or risking jump reproduction that might skip the terminal end section.
2Ease of operation
If manual navigation to terminal end is required, then reproduction position control flexibility is improved, but operation time increases
Solution Approach 1:
The reproduction control apparatus automatically performs the task of positioning at the terminal end section without requiring user intervention. When playback is initiated, the system self-services by automatically jumping to and displaying the terminal end section of the recorded content, eliminating the need for users to manually navigate through the content to verify the terminal end, thus saving time while maintaining operational simplicity.

AI summary
A reproduction control apparatus comprises an instruction means configured to give an instruction so as to move a reproduction position of time series data; and a control means configured to perform, when there is an instruction from the instruction means to move the reproduction position forward, control to move a current reproduction position forward by a first period in a case where a remaining time from the current reproduction position to a terminal end is longer than a total period of the first period and a second period, and to move the current reproduction position to a position that is the second period before the terminal end in a case where the remaining time is less than or equal to the total period and longer than the second period.
