Power Detection Circuitry for Dynamic Resource Allocation in Multimedia Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of individual set-top boxes for each television set and the inefficiency in resource allocation in multimedia distribution systems, where secondary devices are not utilized when a television set is turned off, leading to suboptimal allocation of signal processing and storage resources.
Innovation Solution
A multimedia distribution system that includes a primary receiver device capable of processing multiple channels and distributing them to secondary devices, with power detection circuitry in each device to determine its state and reallocating resources based on usage, allowing for intelligent allocation of tuners and storage resources.

Engineering Contradiction Analysis
1Reliability
If an individual set-top box is provided for each television set, then each television can independently receive and process channels, but the cost increases significantly and resource utilization becomes inefficient
Solution Approach 1:
Multiple television sets share a single set-top box through a network infrastructure. The set-top box processes channels once and distributes the processed signal to multiple displays, eliminating the need for duplicate processing hardware at each television and significantly reducing system cost while maintaining independent reception capability.
Solution Approach 2:
The single set-top box serves multiple television sets simultaneously, performing universal channel processing and distribution functions for the entire group of displays. This multi-functional approach allows one device to replace what would traditionally require multiple separate devices.
2Ease of manufacture
If signal processing resources are concentrated in a primary receiver device, then manufacturing cost of secondary devices is reduced, but resource allocation becomes inefficient when television sets are turned off
Solution Approach 1:
The system implements feedback mechanisms where the primary receiver device receives status information from secondary devices about whether connected television sets are on or off. Based on this feedback, the primary device dynamically reallocates processing resources, assigning active channels to secondary devices when needed and releasing resources when television sets are inactive, thereby optimizing resource utilization efficiency.
Solution Approach 2:
Resource allocation in the system is dynamic rather than static. The primary receiver device can adjust and reallocate processing resources to secondary devices based on real-time usage conditions. When a television set is turned on, resources are allocated to the corresponding secondary device; when turned off, resources are released or reassigned, creating a flexible and adaptive resource management system.

AI summary
A system is described comprising: a local node to distribute multimedia content to a plurality of remote nodes; a power detection module to detect power usage of a multimedia device coupled to a first one of the remote nodes; a power analysis module to determine, based on the detected power usage, whether the multimedia device is in a first power state or a second power state; and a transmitter to transmit an indication of the detected state to the local node, the indication usable by the node to allocate multimedia processing resources across the plurality of remote nodes.
