Streaming Recording Agent for Audiovisual Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in efficiently recording and playing back preferred audiovisual content from numerous streaming sources, such as Internet radio and TV, due to limitations in existing technologies like pre-printed program listings and manual electronic program guides, which are not user-friendly and require advance planning.
Innovation Solution
A personal recording and playback system that automatically receives, stores, and plays back audiovisual streams based on user preferences, using a receiver, memory, and processor to maintain a user profile database, analyze streams, and improve recorded content quality, allowing for background operation and seamless user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual electronic program guides are used for recording preferences, then users can select content to record, but the system requires advance planning and manual intervention which reduces ease of operation
Solution Approach 1:
The system performs self-service by automatically monitoring streaming content, analyzing it against stored user preferences, and recording selected content without requiring manual intervention. The recording agent continuously scans multiple streams, identifies matching content based on user-defined criteria, and handles the entire recording process autonomously, eliminating the need for advance planning by the user.
Solution Approach 2:
The system performs preliminary action by pre-configuring user preferences and content criteria in advance, then automatically executing the recording process when matching content is detected. User preferences are stored and ready before needed, allowing the system to act automatically when conditions are met, rather than requiring real-time manual decisions.
2Productivity
If multiple audio/video streams are recorded simultaneously, then more content is captured, but system complexity increases
Solution Approach 1:
The system segments the recording task by implementing separate specialized components: a recording agent for monitoring and analyzing streams, a preference manager for handling user criteria, and a content analyzer for processing stream data. Each component has a specific function, allowing the system to handle multiple streams efficiently through division of labor rather than a monolithic complex system.
Solution Approach 2:
The recording agent acts as an intermediary between the multiple streaming sources and the recording system. It monitors various streams, filters content based on preferences, and selectively records only matching content, thereby managing multiple streams without proportionally increasing overall system complexity.
3Measurement precision
If automatic content analysis is performed to match user preferences, then recording accuracy improves, but processing time increases
Solution Approach 1:
The system applies partial action by analyzing only the necessary portions of each stream based on pre-defined user preferences. Rather than performing exhaustive analysis on all content, it focuses computational resources on identifying and analyzing segments that match stored criteria, achieving accurate matching while minimizing unnecessary processing time.

AI summary
A personal recorder/playback system (10) includes a recording agent (32) configured to transparently receive multiple audio/visual streams from analog and/or digital sources. The streams are temporarily stored in queues (52,54) for subsequent analysis. The streams, after analysis, are either discarded, stored permanently in an audio/visual collection (48,50), or used to improve the quality of previously stored streams in the collection. The recording agent (32) provides features such as virtual channels (42) and a “top-ten” list (38) of most popular stored audio/visual streams.
