Adaptive Standby Threshold for Audio Video Decoding Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic standby methods for audio/video decoding systems do not adequately consider user habits, leading to unnecessary standby during program broadcasts and lack a simple, cost-effective solution to balance energy efficiency with quick restart capabilities.
Innovation Solution
A method that identifies similar programs based on predefined criteria to determine an inactivity threshold, sending notifications, and initiating standby only after a predefined period, ensuring the system is not put on standby during habitually watched programs, with options for accelerated or conventional standby based on user habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a fixed inactivity threshold is used for automatic standby, then the system can quickly enter standby mode, but it may incorrectly enter standby during habitually watched programs
Solution Approach 1:
The patent applies dynamics by making the inactivity threshold adaptive rather than fixed. The threshold dynamically adjusts based on learned user habits and program characteristics. When similar programs are detected in the database, the system modifies the threshold accordingly, allowing quick standby entry for non-habitual programs while preventing premature standby for habitually watched content.
Solution Approach 2:
The system implements feedback by continuously monitoring user interactions and program viewing patterns, then using this information to refine future standby decisions. The database of previously broadcast programs and user behavior patterns provides feedback that informs the inactivity threshold calculation, creating a closed-loop system that improves accuracy over time.
2Reliability
If user habits are considered for standby decisions, then standby accuracy improves, but system complexity increases
Solution Approach 1:
The patent uses copying by creating a simplified database representation of user habits and program patterns rather than implementing complex real-time analysis. The system copies historical viewing data into a structured database that can be efficiently queried, avoiding the need for sophisticated algorithms while still capturing essential user behavior patterns.
Solution Approach 2:
The system performs preliminary action by pre-processing and storing program information and user viewing patterns in a database before they are needed for standby decisions. This advance preparation allows the system to make quick, accurate standby decisions without performing complex analysis at the moment of decision, thereby reducing operational complexity.
3Loss of energy
If the system monitors program similarity and user habits, then energy savings are optimized, but processing requirements increase
Solution Approach 1:
The patent applies parameter changes by modifying the inactivity threshold parameter based on program similarity and user habit data. Rather than continuously processing complex algorithms, the system adjusts this key parameter according to pre-analyzed data, reducing processing requirements while still achieving optimized energy savings through intelligent standby timing.

AI summary
A method for automatically putting on standby an audio/video decoding system, including: obtaining information representing a program currently being broadcast by the system, referred to as the target program; performing a search for programs similar to the target program in accordance with at least one similarity criterion predefined in a database of information representing programs previously broadcast by the system, the broadcasting having been interrupted by a standby; determining a duration-of-inactivity threshold according to the number of programs similar to the target program; sending a notification intended for a user advising him of the imminent standby of the system if no interaction is noted between the user and system during a period equal to the duration-of-inactivity threshold determined after the end of the target program; and putting the system on standby if no interaction is noted between the user and system during a predefined period after sending of the notification.
