Set-Top Box Message Display Triggered by Remote Activity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current set-top box messaging systems face issues with message visibility due to inconspicuous indicators and the risk of burn-in on television screens, as messages are not displayed effectively when the TV is turned off or unattended, and existing solutions like message lights are easily overlooked.
Innovation Solution
A method and system where set-top-box messages are displayed only upon detection of remote control activity, with the option to sequence through multiple messages and control the display time to prevent burn-in, ensuring messages are viewed without causing irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If messages are displayed on the television screen, then message visibility is improved, but burn-in damage occurs to the screen
Solution Approach 1:
The system displays messages periodically rather than continuously. The message is displayed for a limited duration (e.g., 10-30 seconds) and then automatically removed, allowing the screen to rest. This periodic display pattern ensures the message is visible at the moment of need while preventing cumulative burn-in damage that would occur with continuous display.
Solution Approach 2:
The system dynamically adjusts the display behavior based on remote control activity detection. When remote activity is detected, the message is displayed immediately. When no remote activity is detected for a predetermined period, the display is deactivated. This dynamic adaptation ensures messages are shown when the viewer is likely present while avoiding unnecessary display time that could cause burn-in.
2Reliability
If messages are displayed until viewer response, then message viewing is ensured, but display time becomes excessive causing burn-in
Solution Approach 1:
The system uses remote control activity as feedback to determine when to display messages and when to stop. The processor continuously monitors for remote control signals and uses this feedback to trigger message display only when the viewer is actively using the system. This feedback mechanism ensures messages are viewed when needed while automatically limiting display duration to prevent burn-in.
Solution Approach 2:
The system performs preliminary detection of remote control activity before displaying messages. By detecting remote activity in advance and using it as a trigger, the system ensures the viewer is present and attentive before the message is displayed, increasing the likelihood of successful message delivery while avoiding unnecessary display time.
3Loss of information
If message indicator is placed on set-top box, then message notification is provided, but indicator is easily overlooked
Solution Approach 1:
The system merges the message notification function with the television display function. Instead of using a separate indicator on the set-top box that could be overlooked, the system combines the notification with the TV screen display, which is already the primary viewing device. This integration ensures messages are seen by the viewer without requiring attention to a separate, potentially overlooked indicator.
Solution Approach 2:
The system transitions the notification from a one-dimensional indicator (light or icon on the set-top box) to a two-dimensional display (message on the television screen). This dimensional change provides more space for the message and makes it more conspicuous, as television screens are already the primary visual focus of the viewer.
4Reliability
If television is turned off or switched away, then viewer privacy is maintained, but message cannot be viewed
Solution Approach 1:
The system performs preliminary detection of remote control activity to determine the viewer's presence and intent before displaying messages. When remote activity is detected, the system immediately triggers message display, ensuring the message is delivered at the optimal moment when the viewer is likely present and attentive, rather than waiting for the viewer to actively seek out the message.
Data Source
AI summary
In a set-top-box system, messages from a service provider are stored and delayed until activity from a set-top-box remote is detected. Messages are then generated and provided to a television associated with the set-top-box. Delaying of the message display until set-top-box activity is detected allows short display times, thus preventing burn-in on some television screens, while providing a greater likelihood that messages will be viewed.
