Playback Device Detecting Duplicated Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing playback devices fail to cater to user preferences by automatically deleting or skipping specific parts, such as commercials and duplicated segments, leading to reduced user satisfaction and device usefulness.
Innovation Solution
A playback device that detects and identifies specific parts, including commercials and duplicated segments, and allows users to skip or fast-forward through them upon request, enhancing user control and device functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the device automatically deletes or skips specific parts such as commercials and duplicated segments, then the playback efficiency is improved, but the user satisfaction deteriorates due to loss of control and unintended fast-forwarding
Solution Approach 1:
The device performs preliminary detection and identification of specific parts (commercials, duplicated segments) during the recording phase, storing this information in advance. This allows the playback to efficiently skip or highlight these segments without requiring real-time analysis, thus improving playback efficiency while maintaining user control through informed decision-making
Solution Approach 2:
The device provides visual feedback by displaying icons or indicators on the playback screen to show users which segments are commercials or duplicated parts. This feedback mechanism informs users about the detected segments, allowing them to make informed decisions about whether to skip or view these segments, thereby maintaining user satisfaction
2Adaptability or versatility
If the device provides multiple playback modes to cater to diverse user needs, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The device integrates multiple playback functions (normal playback, skip commercial, fast-forward) within a single unified system. The same detection mechanism identifies both commercials and duplicated segments, and the control system handles multiple playback modes through a common architecture, reducing overall system complexity while providing diverse playback options
Solution Approach 2:
The playback mode is made dynamic and adjustable by the user during operation. Users can switch between different playback modes (normal, skip, fast-forward) based on their current needs, allowing the device to adapt to diverse user preferences without requiring separate dedicated systems for each mode
Data Source
AI summary
A play-back device receiving data including program parts and specific parts, detecting duplicated part in which contents are repeated in the specific part included in the data and before and after the specific part. On playing back the data, when it comes to the specific part or the duplicated part it outputs an indication indicating that it is the specific part or the duplicated part on a display screen. When it receives a skip play-back or fast play-back instruction from a user, it controls to skip play back or fast play back the specific part or the duplicated part. It then becomes possible to provide a play-back device with enhanced usefulness for the user and a method for controlling the same.
