Transport Protocol Selection in Broadcasting Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Broadcasting systems like ATSC 3.0 require a technology that enables multiple transport protocols to coexist, as they need to select and use specific protocols for data transmission efficiently.
Innovation Solution
A transmission apparatus and method that generates and transmits transport protocol selection information, allowing the selection of appropriate protocols from a set of standards, such as ROUTE, MMT, and MPEG2-TS, and a reception apparatus that processes this information to reproduce content accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transport protocols are supported in broadcasting systems, then adaptability and versatility are improved, but device complexity increases due to the need to handle and select between different protocols
Solution Approach 1:
The patent introduces transport protocol selection information as an intermediary element that mediates between multiple transport protocols and the receiving device. This selection information contains identifiers that indicate which transport protocol is used for each service, allowing the receiver to automatically select the appropriate protocol without requiring complex multi-protocol handling capabilities. The intermediary (selection information) simplifies the receiver's task while enabling support for multiple protocols.
Solution Approach 2:
The patent segments the protocol handling function by separating the protocol selection logic from the protocol processing logic. The transport protocol selection information is transmitted as a separate entity that carries protocol identification data, while the actual content is transmitted using different protocols. This segmentation allows the receiving device to first read the selection information, determine the appropriate protocol, and then process the content accordingly, reducing overall system complexity.
2Ease of operation
If transport protocol selection information is transmitted with content, then ease of operation is improved by enabling automatic protocol selection, but loss of information increases due to additional data transmission requirements
Solution Approach 1:
The patent applies partial action by transmitting only the essential protocol selection information rather than complete protocol configuration data. The selection information contains minimal necessary identifiers (such as protocol type indicators) that enable automatic protocol selection without transmitting redundant or excessive data. This approach achieves automatic protocol selection (improving ease of operation) while minimizing the additional data transmitted (reducing information loss).
