Audio Video Replay Tagging via Ambient Sound Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio/video devices do not assist users in determining how much of a missed portion to replay after a disturbance, requiring manual searching which is time-consuming, especially in emergency situations where users may not have time to pause or tag the content.
Innovation Solution
An audio/video device with a microphone and ambient sound analyzer detects disturbing events, generates tags to mark the point of interruption, and allows users to replay from these tags upon request, using a stream processor and tag manager to automatically resume playback from the marked point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual searching is used to find the replay point, then the user can locate the missed content, but the process becomes time-consuming
Solution Approach 1:
The system automatically creates tags at predetermined intervals during playback before the user needs to replay content. These pre-positioned tags serve as ready-made replay points, eliminating the need for manual searching and allowing immediate resumption from the correct position when playback is restarted after an interruption.
2Ease of operation
If the pause feature is used to stop playback during disturbance, then playback can be resumed later, but the user still needs to manually search for the replay point
Solution Approach 1:
The system automatically manages replay points by inserting tags at predetermined intervals without requiring user intervention. When playback is paused or stopped due to disturbance, the system has already prepared multiple potential replay points (tags) that will automatically become available when playback resumes, making the system self-sufficient in managing replay navigation.
3Ease of operation
If tags are created manually at specific points, then replay from those points is enabled, but the user must have time to issue commands during disturbance
Solution Approach 1:
Instead of waiting for the user to manually create tags during or after a disturbance, the system proactively creates tags at predetermined intervals during normal playback. This preliminary action ensures that when an emergency disturbance occurs and the user cannot issue commands, the replay points are already in place and will be automatically available when playback resumes.
Solution Approach 2:
The system performs the tag-creating function automatically without requiring user action. The tag manager continuously monitors playback and inserts tags at predetermined time intervals or position markers, making the system self-sufficient in preparing replay infrastructure regardless of whether the user is available to issue commands.
4Device complexity
If no replay assistance is provided, then the device remains simple, but the user experience deteriorates during interruptions
Solution Approach 1:
The replay assistance function operates automatically in the background without requiring user configuration or intervention. The tag manager silently creates tags at predetermined intervals, and the replay manager automatically utilizes these tags when playback is restarted, providing enhanced user convenience while maintaining interface simplicity because no additional user actions or settings are required.
Data Source
AI summary
The present invention relates to an audio/video device (100) with a replay function containing a stream source (101) providing a replayable audio/video data stream, a user interface (108) for inputting stream play requests, a stream processor (102) coupled to the stream source (101) and to the user interface (108) providing stream play status and processing the stream according to the stream play requests, a tag memory (106) and a microphone (103) receiving ambient sound. To the microphone is coupled an ambient sound analyzer (104) detecting disturbing events, to which is coupled an audio events memory (109) and a tag manager (105) coupled to the stream processor (102) and to the tag memory (106), which upon detecting a disturbing event, generates a disturbing event tag according to stream play status and stores the tag in the tag memory (106), to which is coupled a replay manager (107) coupled to the stream processor (102) and handling stream replay requests by directing a replay of the stream from a point associated with a disturbing event tag.
