Trigger Information Processing for Cable TV Redelivery Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in maintaining the mechanism for terrestrial broadcasting when redelivering broadcast contents via cable television, as the existing systems may not be able to provide services similar to terrestrial broadcasting, necessitating a solution for operating various services in this environment.
Innovation Solution
A receiving device and transmission device that acquire and generate trigger information containing type and channel information, enabling processing and transmission of various functions based on this information, allowing for the operation of multiple services in a redelivery environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If broadcast contents are redelivered via cable television using existing systems, then the broadcasting mechanism can be maintained, but the ability to provide services similar to terrestrial broadcasting is lost
Solution Approach 1:
The receiving device is designed to handle multiple types of trigger information (terrestrial broadcasting format and cable television format) through a unified processing mechanism. The device can identify and process trigger information containing type information indicating its format, allowing it to perform various services (electronic program guide, content redelivery, etc.) across different broadcasting environments without requiring separate specialized systems
2Adaptability or versatility
If trigger information is processed with type identification, then various services can be operated, but the system complexity increases
Solution Approach 1:
The trigger information is segmented into distinct components including type information, channel information, and service-specific data. The receiving device processes these segments separately, first identifying the type information to determine the trigger information format, then extracting and processing relevant service data according to the identified type, which simplifies the overall processing architecture
Solution Approach 2:
Type information acts as an intermediary element that mediates between the heterogeneous trigger information formats and the service processing logic. The receiving device uses this type information to select appropriate processing paths and parameters, enabling flexible service operation without requiring complex conditional logic throughout the entire system
