Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with limited key functionality restrict user control over services like streaming media, requiring multiple key presses for precise time navigation and extended control functions, which is inconvenient and requires hardware/software modifications for additional keys.
Innovation Solution
A method and system that process control messages to trigger shortcut key analysis, allowing extended control operations using existing keys by interpreting sequences and time intervals, enabling richer service control functions without modifying terminal software or hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional dedicated keys are added to the terminal for extended control functions (e.g., double rate forward/backward), then the service control functions are enhanced, but the device complexity and hardware modification requirements increase
Solution Approach 1:
The patent makes existing navigation keys perform multiple functions by introducing a time interval analysis mechanism. The same four navigation keys can now trigger different control operations (normal forward, double rate forward, program switching, etc.) based on the time intervals between consecutive key presses, eliminating the need for additional dedicated keys while achieving extended control functions
Solution Approach 2:
The patent changes the parameter of key press timing by analyzing time intervals between consecutive navigation key presses. Different time intervals correspond to different control operations, allowing the system to distinguish between normal control operations and shortcut operations using the same physical keys, thereby enhancing functionality without hardware modifications
2Measurement precision
If multiple key presses are required for precise time navigation, then control precision is improved, but the ease of operation deteriorates due to the need for multiple operations
Solution Approach 1:
The system performs preliminary analysis of the time intervals between consecutive key presses and automatically determines the appropriate control operation. Instead of requiring users to manually configure multiple parameters for precise navigation, the system pre-establishes time interval thresholds and automatically matches the user's key press pattern to the corresponding precise control function
Solution Approach 2:
The system provides feedback by analyzing the timing pattern of user inputs and automatically adjusting the control operation accordingly. When the user presses navigation keys within specific time intervals, the system recognizes this as a shortcut command and executes the corresponding precise control function, making the complex operation appear simple to the user

AI summary
A method for processing a control message sent by a terminal is provided according to the present invention. The method includes determining whether or not to trigger a shortcut key analysis when the control message is sent from the terminal and accomplishing various extended control operations by a shortcut key analysis. A message processor, a media server, and a media service system are also provided. With the method of the present invention, the terminal may utilize the existing keys to send a series of control messages in accordance with a transmission sequence mechanism recognized by the server. The server may interpret the control message according to a predetermined rule and thus the purpose of extending the service control functions at the terminal side can be accomplished. Accordingly, no modification is needed to the software or hardware of the existing terminal, which bring convenience to the users.
