Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reception device handles various use cases of DVB-GSE packets, then the adaptability and versatility are improved, but the device complexity and costs increase
Solution Approach 1:
The patent segments the GSE packet handling into two distinct paths: GSE-Lite packets with a fixed maximum size of 4096 bytes that can be processed by simple reception devices, and full GSE packets with variable sizes that require complex reception devices. This segmentation allows the system to handle various use cases while maintaining simple device options for common scenarios.
Solution Approach 2:
The patent changes the size parameter constraint from the traditional variable-size GSE packets to a fixed maximum size of 4096 bytes for GSE-Lite packets. This parameter change enables simple reception devices to efficiently process packets without requiring high-functional components, while still maintaining compatibility with DVB-GSE standards.
2Productivity
If high-functional components are used in the reception device, then the productivity and processing capability are improved, but the costs increase
Solution Approach 1:
The patent applies partial action by implementing only the necessary portion of the full GSE protocol functionality in simple reception devices. GSE-Lite reception devices handle only packets with a maximum size of 4096 bytes, which covers many common use cases, without implementing the complete variable-size packet handling capability of full GSE devices. This reduces costs while maintaining adequate processing capability for typical applications.
3Adaptability or versatility
If the PDU size is not limited, then the adaptability is improved, but the device complexity and verification time increase
Solution Approach 1:
The patent changes the size parameter from unlimited/variable to a fixed maximum of 4096 bytes for GSE-Lite packets. This parameter change significantly reduces verification time and device complexity while maintaining adaptability for common use cases. The fixed size constraint simplifies the reception device design and testing requirements.
Data Source
AI summary
The present technology relates to a data processing apparatus, a data processing method, and a program capable of achieving reduction in costs of a reception device that receives a GSE packet. A GSE-Lite packet construction section constructs GSE-Lite packet including GSE-Lite signaling, which is signaling for identifying whether data is the GSE-Lite packet in a data link layer of an open systems interconnection (OSI) reference model, by using, as a target, only a protocol data unit (PDU) whose maximum size is limited to a predetermined limit size of 4096 bytes or less, where the GSE-Lite packet is a generic stream encapsulation (GSE) packet having the PDU placed in a data field. The present technology can be applied to, for example, a case of transmitting the GSE packet and a case of receiving the GSE packet.
