Receiving Apparatus Trigger Routing for External Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of technology for controlling the performance of external devices connected to receiving apparatuses in conjunction with the progress of AV content in digital TV broadcasting, limiting the introduction of advanced services using the Internet.
Innovation Solution
A receiving apparatus and method that extracts trigger information from AV content to control application programs executed by either the receiving apparatus or external devices, allowing commands to be transferred for controlling the execution, registration, start, event firing, suspension, or termination of applications, ensuring synchronized operation with AV content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the receiving apparatus executes application programs locally, then the control functionality is complete, but the device complexity and resource requirements increase
Solution Approach 1:
The system divides the application execution function into two segments: the receiving apparatus executes local applications, while external devices execute remote applications. The trigger information contains device identification that routes commands to the appropriate execution environment, reducing the complexity burden on any single device while maintaining complete control functionality across the system.
Solution Approach 2:
The receiving apparatus is designed with universal control capability that works regardless of whether the application executes locally or on an external device. The trigger processing portion and apparatus control portion handle both local and remote execution scenarios through a unified command routing mechanism based on device identification in the trigger information.
2Adaptability or versatility
If the receiving apparatus manages multiple application programs, then the service capability increases, but the ease of operation decreases
Solution Approach 1:
The receiving apparatus automatically determines whether to execute an application locally or transfer execution to an external device based on the device identification in the trigger information. This self-service mechanism eliminates the need for manual user configuration or complex selection processes, maintaining ease of operation while enabling multi-application service capability.
3Adaptability or versatility
If the system supports both local and external device execution, then the adaptability increases, but the difficulty of detecting and measuring the execution state increases
Solution Approach 1:
The system implements a feedback mechanism where the external device sends execution state information back to the receiving apparatus. The apparatus control portion receives this feedback and can determine the current execution state regardless of whether the application is running locally or on an external device, thus maintaining monitoring capability while supporting flexible execution locations.

AI summary
A receiving apparatus includes: a reception portion configured to receive audio-visual content being transmitted; a trigger extraction portion configured to extract trigger information for controlling an application program for execution either by the receiving apparatus proper or by an external device connected thereto in conjunction with the audio-visual content, the application program being transmitted along with the audio-visual content; an apparatus proper control portion configured such that if a command indicated by the extracted trigger information is destined for the receiving apparatus proper, the apparatus proper control portion controls performance of the application program in accordance with the command; and an external device processing portion configured such that if the command indicated by the extracted trigger information is destined for the external device, the external device processing portion transfers the command to the external device.
