Receiving Apparatus for AV Content Application Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack established methods for providing application programs that can be executed in response to AV content, either through broadcast waves or the Internet, hindering the realization of services that integrate application programs with television programs and online content.
Innovation Solution
A receiving apparatus is designed to receive AV content, acquire trigger information for executing application programs, and control their operation by accessing and managing application programs transmitted via both broadcast waves and the Internet, using features like FLUTE sessions and TPTs to ensure timely and valid execution of commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If application programs are provided through broadcast waves or Internet, then service functionality is improved, but system complexity increases due to multiple acquisition channels
Solution Approach 1:
The receiving apparatus merges multiple acquisition channels (broadcast wave and Internet) into a unified system that can automatically select and switch between sources. The trigger information processing unit consolidates commands from different channels, and the application execution unit provides a common execution environment, thereby reducing perceived system complexity while maintaining multi-channel functionality.
Solution Approach 2:
The receiving apparatus implements a universal application execution environment that can handle application programs from multiple sources (broadcast and Internet). The trigger information processing unit is designed to process commands from either acquisition channel using the same interpretation logic, making the system multi-functional without proportionally increasing complexity.
2Productivity
If trigger information is processed to control application execution, then application responsiveness to AV content is improved, but processing time increases
Solution Approach 1:
The receiving apparatus performs preliminary actions by continuously monitoring and pre-processing trigger information as it arrives from broadcast waves or Internet. The trigger information processing unit maintains a ready state for command interpretation, and the application execution unit pre-loads necessary application programs when triggered, reducing the actual execution delay while maintaining high responsiveness.
3Adaptability or versatility
If application programs are acquired from both broadcast and Internet, then service versatility is improved, but information management complexity increases
Solution Approach 1:
The receiving apparatus segments information management by creating distinct processing paths for broadcast-acquired applications and Internet-acquired applications. The trigger information processing unit separates command sources, and the application execution unit manages different application types independently, reducing overall information management complexity while maintaining versatility.

AI summary
Disclosed herein is a receiving apparatus, a receiving method, and a program which are configured to provide application programs to be executed in response to AV content. The receiving apparatus includes: a receiving block; a trigger acquisition block; an application acquisition block; and a control block. The control block acquires trigger information and, on the basis of a command obtained from the acquired trigger information, acquires a data broadcast application from an application server on the Internet or a data broadcast application transmitted as NRT content of an NRT service using a FLUTE session by referencing an FDT identified by an SMT and an NRT-IT. In accordance with a command obtained from the acquired trigger information, the control block controls an operation of the acquired application program. The present technology is applicable to television receivers configured to receive digital television broadcast signals.
