Application Control via Effective Period Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing application control systems are not flexible enough to control the operation of applications associated with content based on user intention, limiting user control over activation and termination of applications.
Innovation Solution
A receiving device and data processing method that utilize effective period information to control application operations, allowing for two modes: one based on predefined periods and another based on user intention, enabling flexible control through the specification of validFrom and validUntil properties in HLST metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If application control information based on transmitting timing is used, then the application lifecycle can be controlled automatically, but the flexibility to control application operation according to end user intention is insufficient
Solution Approach 1:
The patent introduces dynamic control modes that can switch between automatic period-based control and manual user-based control. The effective period information includes a mode field that determines whether the application should be controlled automatically according to time periods or manually by user operations, enabling the system to adapt its control behavior dynamically based on the specified mode.
Solution Approach 2:
The patent changes the control parameter from fixed transmitting timing to flexible effective period information that includes mode specification. By modifying the application control information structure to include mode parameters (first mode for automatic control, second mode for manual control), the system can adjust its behavior to balance automation and user flexibility.
2Ease of operation
If application operation is controlled strictly according to predefined period, then automatic management is simplified, but user control over activation and termination is limited
Solution Approach 1:
The patent segments the application control functionality into two distinct modes: automatic period-based control and manual user-based control. This segmentation allows the system to provide both automatic management simplicity and user control flexibility by selecting the appropriate mode through the effective period information, rather than forcing a single control approach.
Solution Approach 2:
The effective period information structure serves multiple functions by incorporating a mode field that can specify different control behaviors. The same data structure universally supports both automatic time-based activation/termination and manual user-initiated control, making the system multi-functional and adaptable to different operational requirements.

AI summary
The present technology relates to a receiving device, a transmitting device, and a data processing method that can flexibly control operation of an application associated with content. Effective period information indicating a period in which an application associated with content can specify one of a first mode for controlling operation of the application according to the period and a second mode for controlling the operation of the application according to intention of an end user and, in a case where the second mode is specified as the effective period information, the operation of the application is controlled in response to an operation by the end user. The present technology can be applied to a television receiver or the like, which can receive terrestrial broadcast, for example.
