Audio Video Archiving System Time-Based Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Broadcast audio/video distribution systems face challenges in accessing and storing vast amounts of content for regulatory compliance, as individual stations must maintain records of previously aired content, which is difficult due to the large amount of data involved and storage requirements, especially for multiple channels.
Innovation Solution
An audio/video content archiving system that indexes and stores audio/video content streams by time, allowing for efficient retrieval of specific portions, using a data storage system with a communication interface and control logic to manage indexing, storage, and retrieval of content streams, and optionally metadata streams, facilitating scalable storage solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual television stations record their outgoing audio and video signals to maintain reviewable copies for regulatory compliance, then access to verifiable proof of broadcast content is improved, but the vast amount of data required to be recorded and the total storage necessary become onerous
Solution Approach 1:
The system segments the broadcast content storage by organizing it into channel-specific archives with time-based indexing. Each station's content is separated and stored in dedicated storage regions, allowing efficient management and retrieval without requiring centralized storage of all channels' content simultaneously.
Solution Approach 2:
The system performs preliminary indexing and metadata generation during the recording process itself. By organizing content with timestamps, channel identifiers, and program information as it is recorded, the system eliminates the need for subsequent processing and enables immediate retrieval compliance without additional storage overhead.
2Quantity of substance
If video resolution is reduced below original broadcast quality to decrease storage requirements, then storage capacity needs are reduced, but the quality and detail of verifiable proof deteriorate
Solution Approach 1:
The system dynamically adjusts recording parameters based on content type and regulatory requirements. For programs that may be subject to complaints, the system records at full broadcast quality. For routine programming, lower resolution recording is used, optimizing the balance between storage efficiency and proof quality.
Solution Approach 2:
Different storage quality levels are applied to different content based on its likelihood of being reviewed. High-priority content (news, controversial programs) is stored at full resolution, while routine entertainment content is stored at reduced resolution, ensuring adequate proof quality where needed while minimizing overall storage requirements.
Data Source
AI summary
A method of archiving audio/video content is presented. In the method, a plurality of audio/video content streams is received. Each of the received audio/video content streams is indexed according to time. Each of the indexed audio/video content streams is transferred to a data storage system for storage. A request for a portion of one of the stored audio/video content streams associated with a time period is received. The requested portion of the one of the stored audio/video content streams is retrieved from the data storage system. The requested portion of the one of the stored audio/video content streams is transferred.
