IPTV Set Top Box Sub-Window Key Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IPTV systems face difficulties in launching new functions due to the need for modifying all client services in the network, which is complex and inefficient, especially when integrating multiple content providers and value-added services.
Innovation Solution
A method and device for processing public events through key distribution by creating a sub window, loading a third-party page, displaying it on the current page while hiding the main window, and distributing key messages to both windows to enable corresponding responses based on the message type, allowing both windows to receive and process key messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all client services in the network are modified to support a new function, then the new function can be fully supported, but the complexity and difficulty of launching new functions increases significantly
Solution Approach 1:
The patent segments the client service architecture by introducing a sub-window mechanism that operates independently from the main window. Third-party pages are loaded in sub-windows, allowing them to receive and process key messages independently. This segmentation enables new functions to be added in sub-windows without requiring modifications to all existing client services in the main window, thus resolving the contradiction between adaptability and complexity.
2Ease of operation
If a third-party page is opened in a sub-window, then the main window can be hidden and the sub-window displays the third-party page, but the main window cannot receive key messages when it is hidden
Solution Approach 1:
The patent introduces a key message distribution mechanism that acts as an intermediary between the input device and both the main window and sub-window. When a key message is received, the system distributes it to both windows simultaneously, ensuring that the main window can still receive and respond to key messages even when hidden behind a sub-window. This intermediary mechanism resolves the contradiction between ease of operation and reliability.

AI summary
The present disclosure provides a method and device for processing a public event through key distribution, and a set top box. The method includes: creating a sub window, and loading a third-party page to the sub window; displaying the sub window on a current page, and hiding a main window; and distributing a key message to the main window and the sub window, after receiving the key message; where the key message is used to enable the main window or the sub window to make a corresponding response based on a type of the key message.
