Synchronized Voice Annotation Overlay for CCTV Investigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current investigation process for CCTV footage is inefficient due to the lack of effective annotation methods, leading to miscommunication and repetitive inquiries among investigators, as notes and impressions are not optimally linked with the video clips, causing frustration and potential misinterpretation of details.
Innovation Solution
The method involves encoding and overlaying synchronized voice annotations onto CCTV video clips, allowing multiple investigators to record and selectively play back their impressions, with the ability to mute or unmuting tracks based on hierarchy and relevance, and storing these annotations in a proprietary or common codec format for improved evidence management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If investigators take notes or orally communicate details of the incident, then the investigation process can proceed, but details and observations may be miscommunicated or forgotten
Solution Approach 1:
The patent creates audio copies of investigator annotations that are synchronized with video clips. Instead of manually transcribing or verbally communicating observations, the system records audio annotations that can be played back alongside the video, preserving details without requiring repeated human communication.
Solution Approach 2:
The patent merges multiple investigator annotations into a single synchronized audio track that plays alongside the video clip. This combines multiple perspectives and observations into one integrated package, eliminating the need for separate communications between investigators.
2Reliability
If investigators repeatedly review and communicate incident details across multiple levels, then thorough investigation is achieved, but repetitive inquiries and frustration increase
Solution Approach 1:
The patent records audio annotations during the initial review of video clips, capturing all observations and details at the source. This preliminary documentation eliminates the need for repeated inquiries at higher investigation levels, as all necessary information is already captured and synchronized with the video evidence.
Solution Approach 2:
The system provides feedback to investigators by allowing them to review their own annotations and those of others synchronized with the video clips. This immediate feedback mechanism reduces the need for iterative communications and clarifies understanding without repetitive inquiries.
3Loss of information
If multiple investigators annotate video clips separately, then comprehensive coverage of details is achieved, but the annotations become a jumbled mess not optimally linked with the video
Solution Approach 1:
The patent segments annotations by individual investigators while maintaining synchronization with specific video clips. Each investigator's audio annotation is treated as a separate track that can be independently controlled, allowing comprehensive coverage while maintaining clear organization through temporal and spatial segmentation.
Solution Approach 2:
The patent nests multiple audio annotation tracks within a single video clip package. Each investigator's annotations are nested as separate audio layers that can be selectively played, creating an organized hierarchical structure where comprehensive details are contained within a unified, well-organized container.
Data Source
AI summary
The present invention provides systems and methods for adding voice annotations to CCTV video to aid in incident reporting and investigation. Reviewers and investigators are provided with the ability to record their impressions of an incident by encoding overlapped audio tracks on to a video clip. These overlapped tracks could be multiple in number, enabled or disabled by the listener or subsequent reviewer, without tampering with the content of the originally recorded video or audio. Each audio track represents a voice annotation, and may be assigned to a hierarchical level. The reviewer is provided with the ability to review the video clip along with existing voice annotations while recording the new voice annotation. The resultant overlapped clip file could be made proprietary or stored using a common-codec (like MPEG, MJPEG, AVI, etc) and may be stored on a computer-readable medium.
