Reception Apparatus Interlocked Control via Trigger Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack established methods for controlling the operation of external apparatuses connected to reception apparatuses in synchronization with received AV content during digital broadcasting, especially when utilizing advanced services that integrate Internet functionality.
Innovation Solution
A reception apparatus and method that receives AV content and executes commands to control external application programs, allowing for interlocked operation with external terminals by transmitting and receiving trigger information within the digital television broadcast signal, enabling synchronized operation of data broadcast applications between the reception apparatus and external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reception apparatus executes application programs locally to control operations in interlocked relation to AV content, then the control functionality is available, but the user experience and interaction capability are limited compared to using external terminal apparatuses
Solution Approach 1:
The reception apparatus acts as an intermediary between the digital broadcasting system and external terminal apparatuses. It receives trigger information from the broadcasting signal, processes it locally, and then transmits appropriate commands to external terminals to execute application programs. This mediator role enables external devices to be controlled in synchronization with AV content while maintaining system compatibility
Solution Approach 2:
The system divides the application program execution functionality between the reception apparatus and external terminal apparatuses. The reception apparatus handles trigger information reception and command generation, while external terminals handle application program execution. This segmentation allows each component to specialize in specific tasks, improving overall system efficiency and user interaction capability
2Productivity
If the reception apparatus transmits commands to external terminal apparatuses to execute application programs, then synchronized operation with AV content is achieved, but the system complexity increases
Solution Approach 1:
The reception apparatus pre-processes trigger information received from the digital broadcasting signal before transmitting commands to external terminals. By performing preliminary analysis and command generation at the reception apparatus, the system reduces the processing burden on external terminals and simplifies the overall command transmission protocol
Solution Approach 2:
The reception apparatus is designed with multi-functionality to handle both traditional AV content reception and the additional task of processing trigger information for external terminal control. This universal design allows the same device to serve multiple purposes without requiring separate dedicated hardware for each function

AI summary
The present technology relates to a reception apparatus, a terminal apparatus, a control method, a program, and a communication system for controlling the operation of an external apparatus connected to the reception apparatus in interlocked relation to AV content. The reception apparatus executes a first application program in response to a first command for controlling the operation of the first application program executed in interlocked relation to the AV content; transmits to an external apparatus a second command for controlling the operation of a second application program when the external apparatus is connected to the reception apparatus and targeted to be operated in interlocked relation to the AV content; receives the first command transmitted from the external apparatus executing the second application program; and executes the first application program in response to the received first command. This technology may be applied to a digital broadcast reception apparatus for receiving digital television broadcast signals, for example.
