Receiver Standby Control for Emergency Alert Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency alert systems in broadcasting systems often start receivers in standby mode without user intent, disrupting user convenience by presenting emergency alert information at unintended times.
Innovation Solution
A receiving device and method that instructs a processing part to start and control the presentation of emergency alert information based on emergency alert start information in the broadcast signal, using user-set receiving settings to determine when to present the alert, distinguishing between normal and emergency alert modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiver is forcibly started in standby mode to present emergency alert information, then more receivers can present emergency alert information, but the receiver can be started at a timing not intended by the user, impairing user convenience
Solution Approach 1:
The system dynamically adjusts the receiver's operational state based on real-time conditions. The processing part determines whether to start the receiver by evaluating multiple factors including user settings, alert characteristics, and current operational state, transitioning between standby and active states flexibly rather than forcibly
Solution Approach 2:
The system changes operational parameters such as receiver power state, display mode, and alert presentation characteristics based on the situation. By modifying these parameters dynamically, the system can present emergency alerts reliably while adapting to user preferences and avoiding unnecessary disruptions
2Productivity
If the receiver is forcibly started in standby mode, then emergency alert information can be presented to more users, but unnecessary activations occur at timings not intended by the user
Solution Approach 1:
The system performs preliminary evaluation of alert characteristics and user settings before activating the receiver. By assessing factors such as alert priority, user preferences, and current state in advance, the system ensures that the receiver is only started when truly necessary, avoiding unnecessary energy consumption while maintaining alert delivery effectiveness
Solution Approach 2:
The system incorporates feedback mechanisms that monitor user settings, alert status, and receiver state continuously. This feedback loop allows the processing part to make intelligent decisions about when to activate the receiver, balancing emergency alert delivery with energy efficiency by avoiding unnecessary activations

AI summary
The present technology relates to a receiving device, a receiving method, a signal processing device, and a signal processing method that enable presentation of emergency alert information more appropriately.Provided is a receiving device including: a receiving part that receives a broadcast signal; and a processing part that processes the broadcast signal that has been received, in which the receiving part instructs the processing part in a standby state to start on the basis of emergency alert start information included in the broadcast signal that has been received, and in a case of being instructed by the receiving part to start, the processing part controls presentation of emergency alert information on the basis of signaling including the emergency alert information acquired from the broadcast signal that has been received, and receiving setting information related to a receiving setting of the emergency alert information set by a user. The present technology can be applied to, for example, a television receiver.
