Multimedia Stream Reader Standby via Link Inactivity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia stream reader terminals, such as HDMI keys and TV decoders, continue to consume unnecessary network and energy resources when left active after the user turns off the connected television, due to the lack of efficient methods to detect user inactivity and transition to standby mode.
Innovation Solution
Implementing a method that continuously monitors the state of the communication link between the multimedia stream reader terminal and the restitution terminal, using at least two successive interrogations to detect inactivity, and triggers standby mode with an alert message, reducing the time to detect user disengagement and cutting off the multimedia stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the multimedia stream reader terminal continues to download live digital content indefinitely after the user turns off the television, then the terminal remains ready to provide content quickly, but network bandwidth and energy resources are wasted unnecessarily
Solution Approach 1:
The terminal performs preliminary actions by maintaining a buffer of downloaded content and keeping the streaming session active in the background, so that content can be delivered immediately when needed without requiring continuous active downloading. This allows the terminal to appear ready while actually consuming minimal resources.
Solution Approach 2:
The system dynamically adjusts its operational state based on detected user presence and activity. When user activity is detected, the terminal transitions to full operational mode with active downloading. When no activity is detected for a threshold period, it transitions to a low-power standby mode, dynamically optimizing the balance between readiness and resource consumption.
2Loss of energy
If the terminal automatically goes into standby after a long period of inactivity (e.g., 4 hours), then energy consumption is reduced, but the user experience is degraded if they return sooner and find the terminal unresponsive
Solution Approach 1:
The terminal performs preliminary actions by maintaining a buffered content cache and keeping the streaming protocol session alive in a low-power state. This preliminary preparation ensures that when the user returns, content can resume immediately from the buffer without requiring full re-initialization, thus maintaining reliability while reducing energy consumption during idle periods.
Solution Approach 2:
The system changes operational parameters based on idle time duration. During short idle periods, the terminal maintains higher readiness parameters (active downloading, full buffer). During longer idle periods exceeding the threshold, it transitions to lower power parameters (standby mode, minimal buffering), dynamically adjusting the balance between energy savings and service availability.
3Loss of energy
If the terminal detects link inactivity through successive interrogations and places itself on standby quickly, then resource consumption is minimized, but the detection mechanism becomes more complex
Solution Approach 1:
The terminal implements a feedback mechanism where it periodically interrogates the link status and uses this feedback to determine when to transition to standby mode. The successive interrogations create a feedback loop that monitors user engagement, allowing the system to make informed decisions about when to conserve resources while keeping the logic relatively simple through standardized polling intervals and threshold-based responses.

AI summary
A method for managing standby of a multimedia stream reader terminal, which is associated with a multimedia content restitution terminal via a communication link. The multimedia stream reader terminal detects a state of a link between the multimedia stream reader terminal and the restitution terminal on the communication link and goes into standby mode in the event of detection of an inactive state of the link.
