Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia systems lack efficient methods for transmitting and receiving signaling information and event notifications necessary for application program services across hybrid broadcast and communication networks, particularly in MPEG media transport (MMT) systems, which hinders the provision of rich and interactive multimedia services.
Innovation Solution
The proposed solution involves an apparatus and method for transmitting and receiving event information in a multimedia system using MMT technology, where event notifications are embedded within data units and signaling messages, allowing terminals to recognize and execute actions related to application program services by parsing MMT signaling messages and media processing units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If event information is embedded within data units and signaling messages in MMT systems, then terminals can recognize and execute actions related to application program services, but the system complexity increases due to the need for parsing and processing embedded event notifications
Solution Approach 1:
The event information is segmented and embedded within specific data units and signaling messages in the MMT system. The notification is divided into distinct components that can be independently parsed and processed, allowing terminals to extract and execute specific actions without overwhelming complexity
Solution Approach 2:
The patent introduces an intermediary mechanism where event information is transmitted through signaling messages that act as mediators between the broadcast/communication network and the terminal application. This intermediary layer standardizes the notification format, simplifying terminal processing while maintaining versatility
2Adaptability or versatility
If signaling information is transmitted for application program services in hybrid broadcast and communication networks, then rich and interactive multimedia services can be provided, but the loss of information increases due to potential errors in transmitting event notifications
Solution Approach 1:
The patent implements feedback mechanisms where the transmission and reception of event information includes verification and acknowledgment processes. This ensures that event notifications are accurately transmitted across hybrid networks, reducing information loss while maintaining service richness
Solution Approach 2:
The system employs error protection and redundancy measures beforehand in the transmission of signaling information. By preparing corrective mechanisms in advance, the patent cushions against potential transmission errors in hybrid networks, ensuring reliable delivery of event notifications
