Change Object Streaming for Real-Time Data Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data distribution services, such as DVB-T, face challenges in quickly transmitting important, real-time data like teletext pages or ESGs, as they require predefined transmission patterns and long reaction times, making it difficult to prioritize current information and maintain real-time transmission.
Innovation Solution
A method and system where a change object is formed based on information items and change rules, allowing for fast communication through streaming transmission, enabling quick updates to static objects with error protection and synchronization across receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carousel transmission with predefined transmission patterns is used, then data distribution service can maintain stable transmission, but reaction time increases and real-time data transmission becomes difficult
Solution Approach 1:
The patent segments the transmission system into two independent channels: carousel transmission for static objects and streaming transmission for change objects. This segmentation allows each channel to operate independently with its own characteristics, enabling stable static object distribution while simultaneously supporting real-time updates without requiring changes to the predefined transmission pattern
Solution Approach 2:
The patent introduces change objects as intermediaries that carry update information for static objects. Instead of modifying the transmission pattern or retransmitting entire static objects, the system uses change objects transmitted via streaming to convey minimal update information, which reduces reaction time while maintaining the stability of the carousel transmission
2Device complexity
If transmission pattern is predefined, then system complexity is reduced, but adaptability to prioritize current information decreases
Solution Approach 1:
The patent introduces dynamic adaptability through change objects that can be transmitted via streaming transmission. While the carousel transmission pattern remains static and predefined, the system dynamically prioritizes current information by inserting change objects into the streaming channel, allowing the system to adapt to time-critical updates without modifying the underlying carousel structure
Solution Approach 2:
The patent maintains periodic carousel transmission for static objects while overlaying it with on-demand streaming transmission of change objects. This periodic action ensures that the predefined transmission pattern continues to operate reliably, while the streaming channel provides periodic or event-driven updates as needed, combining the benefits of both approaches
3Duration of action of stationary object
If static objects are buffer-stored in receiver, then data can be retrieved later, but real-time evaluation is delayed
Solution Approach 1:
The patent applies preliminary action by transmitting change objects via streaming transmission before the receiver needs to evaluate or act on the updated information. This allows the receiver to be notified of changes in real-time and immediately evaluate updated static objects without waiting for the next carousel transmission cycle or for data to be fully buffered

AI summary
Certain exemplary embodiments can provide and/or utilize a system, device, and/or method for managing changes to data, such as a method that includes transmitting a change to a static object (SO1) by means of a change object (SO*) in a data distribution service that communicates a plurality of static objects (SO1, . . . , SO5) via a carousel transmission (KUE) and real time data (RD) via a streaming transmission (SUE), wherein the change object (SO*) is formed on the basis of at least one information item (I*) to be changed and on the basis of at least one change rule (R*) specifying a procedure for carrying out the change, and the change object (SO*) is communicated via the streaming transmission (SUE).
