Reception Apparatus Triggered Application Control via Broadcast Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in providing application programs that can be executed in interlocked relation to AV content, such as TV programs and CMs, without requiring extensive refurbishment of broadcast channel equipment or obtaining permission from broadcast operators.
Innovation Solution
A reception apparatus that receives AV content, acquires trigger information for operating application programs, and uses a correspondence table to control the operation of these programs based on the progress of the AV content, allowing for the execution of applications without direct metadata access or equipment refurbishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If application programs are executed in interlocked relation to TV programs using conventional broadcast systems, then the service functionality is improved, but extensive refurbishment of broadcast channel equipment and permission from broadcast operators are required
Solution Approach 1:
The patent extracts the metadata and trigger information directly from the broadcast signal itself rather than requiring separate equipment or operator permissions. The reception apparatus acquires trigger information embedded in the broadcast signal to control application programs, eliminating the need for extensive equipment refurbishment while maintaining service functionality.
2Ease of manufacture
If trigger information is acquired from broadcast signals to control application programs, then the need for equipment refurbishment is reduced, but the precision of timing control must be maintained
Solution Approach 1:
The reception apparatus uses feedback mechanisms to monitor the progress of AV content and compare it with the valid time of commands from the correspondence table. The control portion continuously checks whether the current time satisfies the validity condition, ensuring precise timing control even when acquiring trigger information from broadcast signals without extensive equipment modification.
3Extent of automation
If a correspondence table is used to associate commands with valid times, then the control of application programs becomes more automated, but the complexity of data management increases
Solution Approach 1:
The correspondence table is designed to be self-managing within the reception apparatus. The control portion automatically acquires the correspondence table from the broadcast signal, extracts trigger information, and executes commands based on the valid time conditions without requiring external manual intervention or complex data management infrastructure, thereby achieving automation while keeping data management relatively simple.

AI summary
Disclosed herein is a reception apparatus including: a reception portion configured to receive AV content; a trigger acquisition portion configured to acquire trigger information for operating an application program to be executed in interlocked relation to the AV content; a table acquisition portion configured to acquire a correspondence table associating a command for controlling the operation of the application program with a valid time of the command; and a control portion configured such that when the time acquired from the trigger information as indicative of the progress of the AV content satisfies a predetermined condition of validity in reference to the valid time of the command on the basis of the acquired correspondence table, the control portion controls the operation of the application program in accordance with the command being valid.
