Recording Device Data Element Arrangement for High-Speed Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording technologies face challenges in recording video and audio data on information recording media in a way that enables high-speed editing and reproduction operations, particularly when auxiliary data, metadata, and other related data need to be efficiently managed and accessed.
Innovation Solution
A recording apparatus and method that divides video and audio data into elements, arranges them with metadata and auxiliary data, and records them on an information recording medium such that metadata and auxiliary data are adjacent or ahead of video data elements, optimizing sector unit sizes and ECC block alignment for rapid access and editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video data and audio data are recorded separately without coordinated arrangement, then the recording structure is simple, but editing and reproduction operations cannot be performed at high speed
Solution Approach 1:
The patent divides video data into video data elements and audio data into audio data elements, where each element corresponds to a predetermined time period. This segmentation allows for independent processing and arrangement of video and audio data, enabling high-speed editing and reproduction operations by treating them as discrete, manageable units rather than continuous streams.
Solution Approach 2:
The patent combines video data elements and audio data elements into recording units where both types of data are arranged and recorded together. This merging ensures that video and audio data corresponding to the same time period are stored in close proximity, allowing for synchronized playback and editing operations at high speed without requiring complex coordination between separate data streams.
2Productivity
If data related to video and audio (auxiliary data, metadata) are recorded separately, then the recording structure is simple, but editing and reproduction operations cannot be performed at high speed
Solution Approach 1:
The patent integrates auxiliary data and metadata with video and audio data elements into unified recording units. By arranging related data (video data, audio data, auxiliary data, and metadata) together in the same recording unit, the system enables high-speed access and processing operations, as all necessary data for a complete media element are available simultaneously rather than scattered across separate locations.
3Speed
If data are arranged for sequential access, then the storage structure is simple, but high-speed random access and search operations cannot be performed
Solution Approach 1:
The patent segments data into discrete elements (video data elements, audio data elements) that can be independently accessed. Each element is marked with identification information that enables rapid location and access to specific time periods or content segments, allowing for high-speed random access and search operations without requiring complex data structures.
Solution Approach 2:
The patent incorporates identification information and metadata that describe the content and location of data elements before actual access is needed. This preliminary organization of data with descriptive markers enables the system to quickly locate and access specific video or audio segments during search or random access operations, significantly improving access speed without requiring complex real-time processing.
