Multimedia System Audio Trigger Markers Synchronized Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia systems face challenges in efficiently managing and storing large amounts of multimedia data, particularly in correlating and searching audio and text comments in relation to video data, leading to cumbersome retrieval of relevant information.
Innovation Solution
A multimedia system that includes audio and text comment input devices, a media processor to generate synchronized audio and text trigger markers, and a media server to combine these into a searchable media data stream, allowing for efficient storage and retrieval of comments correlated with video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If audio and text comments are stored separately from video data, then storage management is simpler, but retrieval and correlation of relevant information becomes time-consuming and cumbersome
Solution Approach 1:
The patent combines video data, audio comments, and text comments into a single integrated media data stream using a unified data structure. This merging allows all comment types to be retrieved together with their corresponding video segments through a single search operation, eliminating the need to separately manage and correlate multiple data files, thus dramatically improving retrieval efficiency while the structured design maintains manageable complexity
Solution Approach 2:
The patent introduces trigger markers as intermediary elements that link comments to specific video segments. These markers serve as synchronization points that enable the system to efficiently locate and retrieve relevant video portions along with associated audio and text comments, acting as a mediator between the comment data and video data without requiring complex cross-referencing
2Loss of information
If all multimedia data is processed and stored in detail, then information completeness is improved, but processing time and storage requirements increase
Solution Approach 1:
The patent extracts only the essential synchronization information (trigger markers) from the full audio and text comment data. Instead of processing and storing all comment data in detail, the system extracts key trigger points that mark where comments occur in the video timeline. This extraction maintains information completeness for retrieval purposes while dramatically reducing processing time and storage requirements by working with a condensed representation
3Measurement precision
If audio trigger markers are generated for every comment occurrence, then search accuracy is improved, but data volume and processing load increase
Solution Approach 1:
The patent segments the continuous audio and text comment data into discrete trigger marker events synchronized with video segments. Instead of creating data structures for every individual comment word or phrase, the system segments comments into meaningful trigger events that occur at specific timestamps. This segmentation maintains search accuracy by preserving the temporal and contextual relationships while significantly reducing data volume compared to storing complete comment transcripts
Data Source
AI summary
A multimedia system may include at least one audio comment input device configured to permit at least one commentator to generate audio comment data based upon viewing video data from a video source. Furthermore, a media processor may cooperate with the at least one audio comment input device and be configured to process video source data and audio comment data and generate therefrom audio trigger markers synchronized with the video source data for predetermined audio triggers in the audio comment data, and combine the video source data, the audio comment data, and the audio trigger markers into a media data stream.
