ESG Fragment Notification Parameters for Timely Service Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks lack an effective method for notifying users of changes or updates in service guide information, such as schedule alterations or new content, in a timely and efficient manner.
Innovation Solution
A system and method for transmitting Electronic Service Guide (ESG) fragments that include notification parameters, such as a notification reception parameter, notification services parameter, and notification component parameter, to enable users to receive timely updates and changes in service information through specific ports and protocols like UDP/IP, allowing for user-oriented or terminal-oriented notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If ESG fragments are transmitted through broadcast/multicast networks, then information can be delivered to multiple users simultaneously, but there is no effective method to notify users of changes or updates in service guide information in a timely manner
Solution Approach 1:
The notification system segments information delivery by creating distinct notification ESG fragments that are separate from regular service guide fragments. These notification fragments contain specific parameters (notification reception parameter, notification services parameter, notification component parameter) that enable targeted delivery of change information to users, allowing timely notification without disrupting the existing broadcast structure.
Solution Approach 2:
The patent introduces notification ESG fragments as an intermediary mechanism between the service provider and users. These fragments act as carriers that transport notification information through the broadcast/multicast network, enabling the service provider to communicate service changes, schedule alterations, or new content to users in a timely and efficient manner while maintaining compatibility with existing ESG infrastructure.
2Reliability
If traditional ESG fragments are used without notification parameters, then the system maintains simplicity, but users cannot be informed of upcoming events, schedule changes, or updates
Solution Approach 1:
The notification system applies local quality by adding specific notification parameters only to ESG fragments that require user notification, rather than modifying all ESG fragments uniformly. The notification reception parameter, notification services parameter, and notification component parameter are selectively included in fragments containing service changes, schedule alterations, or new content, maintaining simplicity for regular fragments while enabling reliable notification where needed.

AI summary
Provided are apparatuses and methods in a digital broadcast transmission system for transmitting a notification from a transmitter to a receiver or subscriber station. The notification may inform the user or subscriber of information regarding upcoming events, programs or services, changes to existing events, programs or services, advertisements, emergency announcements, and the like. In one example, a parameter is included in the ESG fragment transmitted to a receiver for indicating that the service associated with the ESG fragment is a notification. In another example, the ESG fragment is an access fragment containing a type parameter for indicating that the notification associated with the access fragment is a component of the corresponding service.
