Automatic Source Concentrator for Multimedia Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia systems require manual user intervention to select and prioritize sources, leading to cumbersome operations when multiple sources are simultaneously active, and do not automatically adapt to changing user intentions.
Innovation Solution
Implementing a method for dynamic priority allocation among sources, where the highest priority is assigned to the source actively sending data, allowing automatic switching and pausing of sources without user intervention, using a source identifier and status indicator, and a multi-level stack for managing source queues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user intervention is used to select sources, then the system can reliably control source selection, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system automatically detects source activation states and performs source selection without user intervention. The source concentrator monitors activation indicators from connected sources and autonomously switches between sources based on their active state, making the system serve itself rather than requiring manual user control.
Solution Approach 2:
The system uses feedback from activation indicators sent by connected sources to automatically determine which source should be active. When a source sends an activation indicator, the concentrator detects this feedback and automatically switches to that source, creating a closed-loop control system that responds to source states.
2Adaptability or versatility
If static priority hierarchies are assigned to sources, then source conflicts can be resolved systematically, but the system cannot adapt to changing user intentions dynamically
Solution Approach 1:
The system dynamically adjusts source priorities in real-time based on activation indicators rather than using fixed static priorities. When a source becomes active, its priority automatically increases, and when inactive, its priority decreases, allowing the system to adapt to changing user intentions without complex priority management mechanisms.
3Extent of automation
If automatic source detection is implemented, then user interaction is reduced, but the system may not reliably distinguish between intentional activation and incidental signals
Solution Approach 1:
The system uses activation indicators as intermediary signals between sources and the concentrator. These standardized indicators serve as a reliable communication mechanism that clearly distinguishes intentional source activation from incidental signals, enabling the concentrator to reliably detect when a user intends to use a particular source.

AI summary
The invention relates to a concentrator for coupling a plurality of digital or analog sources to an audio/video reading system capable of reading one of said sources. Each of the available sources is associated with a source identifier and an identifier for indicating an activated or deactivated state after a user's action on a source. A register (42) stores an identifier of the current source being read, while a LIFO stack with multiple levels (44) stores an ordered list of identifiers of other sources in reading standby. Upon the activation of a new source, an automatic means replaces the register content with the identifier of the new source in order to replace the current source with the new source so that the system can read it, and simultaneously adds to the stack the identifier of the current source. The reverse operation is carried out upon a deactivation of the current source in order to replace the current by the last source contained in the stack and to allow the system to read the same.
