Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and complexity of reception devices for DVB-GSE packets due to the need to handle various use cases and potential new use cases, leading to expensive and time-consuming verification processes and latency issues.
Innovation Solution
A data processing device and method that restricts the maximum size of PDUs to 4096 bytes or less, structuring sGSE packets and using sGSE signaling to identify the packet type at the data link layer or lower, allowing for simpler and less expensive device configuration without the need for sophisticated components like CPUs or FPGAs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reception device handles various use cases according to the general DVB-GSE standard, then the adaptability and versatility are improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent segments the GSE packet handling into two distinct types: regular GSE packets and sGSE packets. By introducing a packet type identification mechanism, the reception device can selectively process different packet types using different methods, thereby reducing overall complexity while maintaining versatility.
Solution Approach 2:
The patent applies partial action by implementing a simplified processing path for sGSE packets that targets only the most common use case (PDU size ≤ 4096 bytes). This partial implementation reduces device complexity while still covering the majority of practical applications.
2Productivity
If sophisticated components like CPUs or FPGAs are used in the reception device, then the processing capability is improved, but the cost increases
Solution Approach 1:
The patent enables the use of simpler, cheaper components by introducing a deterministic packet processing model. The sGSE packet format with fixed PDU size constraints allows reception devices to use cost-effective hardware configurations rather than requiring expensive sophisticated components.
3Reliability
If verification of the reception device is performed comprehensively for all use cases, then the reliability is improved, but the verification time increases
Solution Approach 1:
The patent segments the verification process into distinct paths for regular GSE packets and sGSE packets. This segmentation allows verification to be performed separately for each packet type, reducing the overall verification time while maintaining comprehensive coverage of all use cases.
4Adaptability or versatility
If the PDU size is not restricted, then the adaptability is improved, but the latency increases
Solution Approach 1:
The patent applies local quality by imposing PDU size restrictions specifically on sGSE packets while leaving regular GSE packets unaffected. This localized constraint reduces latency for time-sensitive applications without compromising the overall adaptability of the system.
Data Source
AI summary
The present technology relates to a data processing device, a data processing method, and a program capable of realizing low cost of a reception device receiving a GSE packet conforming to DVB-GSE. An sGSE packet structuring unit sets, as a target, only a PDU (Protocol Data Unit) of which a maximum size is restricted to a predetermined restriction size equal to or less than 4096 bytes and structures an sGSE packet which is a GSE packet in which the PDU is deployed in a data field and which conforms to DVB (Digital Video Broadcasting)-GSE (Generic Stream Encapsulation). The present technology is applicable, for example, when the GSE packet is transmitted or received.
