Solution Overview
Problem
Current systems lack a technological framework to provide an application program executed in a linked relationship with digital television programs without requiring installation of specialized broadcasting transmission lines or modifications to terminals, and obtaining licenses from broadcasting organizations.
Innovation Solution
A reception apparatus and method that utilize trigger information embedded in digital television broadcasting signals to control the execution of application programs, including acquisition, startup, event firing, suspension, and termination, using time information and identification data to synchronize with the AV content, allowing for the execution of application programs without direct modification or licensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reception apparatus receives digital television broadcasting signal through a broadcasting transmission line such as CATV network or satellite communication network, then the service of executing application program linked with digital television program can be implemented, but installation of broadcasting transmission line and modification to terminal for exclusive use are involved, and license of broadcasting organization is demanded
Solution Approach 1:
The reception apparatus is designed to handle both traditional broadcasting signals and application program delivery through a unified interface. The control section can process commands from either broadcast trigger information or external communication interfaces, making the terminal multi-functional without requiring separate specialized equipment for different service types.
Solution Approach 2:
The patent introduces a command structure that acts as an intermediary between the broadcasting transmission line and the application program execution. The control section receives commands containing application program identification information and execution conditions, translating broadcast signals into actionable instructions without requiring direct modification of the terminal hardware or exclusive licensing.
2Extent of automation
If trigger information is extracted from AV content to control application program execution, then the application program can be executed interlocking with AV content progress, but the system requires specialized infrastructure and licensing
Solution Approach 1:
The reception apparatus autonomously extracts trigger information from the AV content broadcast signal and automatically controls application program execution based on the extracted trigger type. The control section independently determines when to activate, dispatch events, or terminate application programs without requiring external intervention or specialized infrastructure, reducing system complexity while maintaining automated control.
3Adaptability or versatility
If application program is provided through broadcasting transmission line, then seamless integration with existing broadcasting system is achieved, but installation and licensing requirements increase complexity
Solution Approach 1:
Instead of requiring the broadcasting transmission line to be modified to support application program delivery, the patent inverts the approach by making the reception apparatus capable of interpreting standard broadcast signals as command instructions. The control section parses trigger information from conventional AV content broadcasts and converts it into application program execution commands, eliminating the need for infrastructure modification and simplifying deployment.

AI summary
The technology disclosed herein relates to a reception apparatus, a reception method, a program and an information processing system which can provide an application program which is executed in a linked relationship with an AV content such as a digital television program. A reception apparatus receives an AV content, and extracts trigger information transmitted together with the AV content for rendering an application program, which is to be executed in a linked relationship with the AV content, operative. The reception apparatus also acquires a command for controlling the operation of the application program in response to the extracted trigger information, and controls the operation of the application program in response to the acquired command. The technology can be applied, for example, to a television receiver which receives a digital television signal.
