ESG Fragment Service Type Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Electronic Service Guides (ESGs) face complexity in maintaining accurate information about service types and interactivity, making it difficult to add new service combinations and indicating the type of interactivity provided.
Innovation Solution
Incorporating specific parameters or attributes in ESG fragments to indicate the type of program or service and associated interaction, allowing for clear and comprehensive representation of service information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If service types and interactivity are combined in a single enumeration in the ESG, then comprehensive service information is provided, but the complexity of maintaining and updating the enumeration increases significantly
Solution Approach 1:
The patent divides the service information into separate elements: service type indicators and interactivity type indicators are independently defined and maintained. This segmentation allows each element to be updated and managed separately, reducing the complexity of maintaining a combined enumeration while preserving complete service information.
Solution Approach 2:
The patent creates a universal framework where service types and interactivity types are defined as separate可组合 elements. This multi-functional approach allows the same service type to work with multiple interactivity types, reducing the need for a complex unique enumeration for every possible combination.
2Measurement precision
If a detailed enumeration of all service and interactivity combinations is maintained, then accurate service information is indicated, but adding new service combinations becomes difficult and time-consuming
Solution Approach 1:
By segmenting service information into independent service type and interactivity type indicators, the patent enables accurate service indication while allowing flexible addition of new combinations. New services can be introduced by adding new indicator values rather than updating a comprehensive combination enumeration.
Solution Approach 2:
The patent implements a dynamic system where service types and interactivity types can be independently extended. The separation allows the enumeration to adapt to new service combinations without requiring comprehensive pre-definition, enabling the system to evolve as new services are introduced.
3Loss of information
If interactivity information is included in the service type enumeration, then complete service description is achieved, but the difficulty of maintaining accurate information increases
Solution Approach 1:
The patent segments interactivity information into a separate indicator from service type information. This segmentation maintains complete interactivity information while significantly easing maintenance, as each segment can be updated independently based on its specific requirements without affecting the other.
Solution Approach 2:
The patent introduces separate indicator parameters as intermediaries between the service type and interactivity characteristics. These intermediaries carry the necessary information independently, reducing the complexity of maintaining accurate interactivity information while preserving completeness.

AI summary
Provided are apparatuses and methods in a digital broadcast transmission system for transmitting information on a type of service or program and/or interactivity or interaction information for the service or program. In one example, a parameter or attribute is provided in an ESG fragment for indicating the type of program or service and the type of interaction associated with the program or service. In another example, a first parameter is provided for indicating the type of program or service and a second parameter is provided for indicating the type of interaction associated with the program or service. The parameter or attribute may be included in metadata of the ESG fragment.
