Data Carousel Update Element for Flexible Check Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcasting systems, such as DVB and OMA, face inflexibility in updating data elements within a data carousel due to rigid time periods for checking and validity periods, leading to high administrative costs and bandwidth usage, as well as inability to detect irregular updates before validity ends.
Innovation Solution
A method and device that allow for flexible updating of data elements by adding an updating element indicating the time or time period for checking, enabling individual determination of update times for each group of data elements, and including a status element to differentiate between regular and irregular updates, allowing for efficient resource use and timely detection of updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid time periods for checking data elements are used as prescribed by global guidelines, then the system follows standardized procedures, but the system lacks flexibility in adapting check intervals and cannot detect irregular updates before validity ends
Solution Approach 1:
The patent changes the parameter of check interval from a fixed global value to a dynamic value that can be individually specified for each data element through updating elements. This allows the check interval to be adapted based on the specific update characteristics of each element, resolving the contradiction between flexibility and complexity.
Solution Approach 2:
The patent segments the data carousel into individual data elements, each with its own updating element specifying check intervals. This segmentation allows independent control of check frequencies for different elements, enabling flexible adaptation without requiring complex global management mechanisms.
2Reliability
If validity periods are assigned to each data element to prevent use after expiration, then data freshness is controlled, but bandwidth is wasted transmitting validity information and administrative costs increase
Solution Approach 1:
The patent extracts the check interval specification from the validity period information. Instead of transmitting full validity period data, only the essential check interval parameter is included in updating elements. This reduces the quantity of transmitted information while maintaining the ability to control data freshness.
3Reliability
If all data elements are checked for updates at regular intervals, then comprehensive update detection is achieved, but resource consumption increases significantly
Solution Approach 1:
The patent applies partial action by checking only those data elements that have updating elements with specified check intervals. Elements without such elements are not subjected to frequent checks. This selective approach maintains reliable update detection for critical elements while reducing overall resource consumption.
4Loss of time
If frequent checking of data elements is performed to detect irregular updates, then update timeliness is improved, but bandwidth and processing resources are wasted on unnecessary checks
Solution Approach 1:
The patent changes the check frequency parameter dynamically based on the updating element specifications for each data element. Elements requiring timely detection of irregular updates have shorter check intervals, while stable elements have longer intervals or none. This parameter adaptation achieves timely detection without uniform frequent checking of all elements.
