Synchronous Data Tracks in Media Editing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media editing systems limit the ability to edit time-synchronous adjunct data independently of audio and video tracks, restricting flexibility and efficiency in manipulation and synchronization.
Innovation Solution
A method and system that represent time-synchronous data as distinct entities, allowing independent editing and conversion into a flexible format for analysis and synchronization with media tracks, enabling users to perform editing operations on both media and data tracks while maintaining temporal synchrony, and allowing selective output and conversion for searchable media asset management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If time-synchronous adjunct data are embedded within the audio or video signal, then the data can be transmitted and stored together with media content, but the ability to edit or manipulate the data streams independently of picture and audio tracks is limited
Solution Approach 1:
The patent segments the media composition into separate editable tracks: media tracks for picture and audio content, and distinct data tracks for time-synchronous adjunct data. This segmentation allows independent editing operations on each track type while maintaining their temporal relationships through the unified timeline structure.
Solution Approach 2:
The patent extracts time-synchronous adjunct data from being embedded within audio/video signals and places them in separate data tracks. This extraction enables independent manipulation of data streams while preserving their time-synchronization with media content through time address references.
2Adaptability or versatility
If data are placed in ancillary portions of digital video broadcasts or embedded in media files, then synchronization with media content is maintained, but flexibility in data manipulation and analysis is reduced
Solution Approach 1:
The patent introduces time addresses as an intermediary mechanism that links data packets to specific media elements. Each data packet contains a time address reference that acts as a mediator, maintaining temporal synchronization with media content while allowing the data to be stored and edited independently in separate tracks.
Solution Approach 2:
The patent adds a new dimension to data organization by introducing explicit time address references in data packets. This dimensional addition allows data to be positioned in time independently of their physical storage location, enabling both flexibility in manipulation and reliability in synchronization.
3Productivity
If editors can only perform operations on embedded data within media files, then system complexity is reduced, but productivity in editing and producing media with adjunct data is limited
Solution Approach 1:
The patent creates a universal timeline structure that handles multiple track types (media tracks and data tracks) with a single interface. This multi-functional timeline allows editors to perform consistent editing operations across different data types, improving productivity without proportionally increasing system complexity.
Data Source
AI summary
A media editing system provides an editor with full visibility and editing capability for synchronous data that is adjunct to audio and video. The data tracks include one or more streams of data packets, each stream being of a particular data type. Synchronous data tracks are displayed on the timeline, facilitating data track editing independent of the associated media tracks. The UI also enables selective playback and export of the data tracks along with the corresponding video and audio. The system also enables data streams to be filtered and combined. Data from the data tracks can be extracted and imported into a media asset management system, enabling the data to be searched.
