Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmitting devices face challenges in minimizing the impact of packet errors during data transmission, particularly in digital broadcasting and internet protocol-based systems, where padding insertion methods do not effectively manage packet boundaries and errors across multiple channels.
Innovation Solution
A transmitting device and method that inserts padding into packets based on the number and lengths of packets in a frame, ensuring that packet boundaries are aligned and padding is distributed across multiple packets to minimize error influence, while also considering header lengths and bit allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If padding is inserted into packets to minimize error impact, then reliability is improved, but device complexity increases due to the need to calculate and manage packet boundaries, header lengths, and padding distribution across multiple packets
Solution Approach 1:
The patent divides the padding insertion process into discrete steps: calculating total padding length based on frame parameters, determining individual packet padding amounts, identifying packet boundaries, and distributing padding across selected packets. This segmentation of the complex task into manageable components reduces processing complexity while maintaining reliability improvements.
Solution Approach 2:
The patent performs preliminary calculations of packet lengths, header lengths, and required padding amounts before actual packet construction. By pre-calculating these parameters and determining the optimal distribution of padding across packets beforehand, the system avoids complex real-time decisions during transmission, thereby reducing operational complexity while ensuring reliable error mitigation.
2Reliability
If padding is distributed across multiple packets with aligned boundaries, then error influence is minimized, but transmission time increases due to additional processing steps
Solution Approach 1:
The patent segments the padding distribution task by calculating padding requirements for individual packets based on their specific lengths and boundaries rather than treating the frame as a single unit. This allows parallel processing of multiple packets with predetermined padding amounts, reducing overall processing time while maintaining error resistance through distributed padding.
Solution Approach 2:
The system performs all necessary calculations for padding distribution, packet boundary alignment, and length adjustments in advance, before the actual packet assembly and transmission. This preliminary action ensures that during the critical transmission phase, no additional time-consuming computations are required, thus minimizing transmission delays while achieving robust error protection.
3Manufacturing precision
If packet boundaries are aligned and padding is inserted based on precise length calculations, then manufacturing precision is improved, but device complexity increases due to the need for accurate tracking of packet lengths and boundaries
Solution Approach 1:
The patent breaks down the boundary alignment process into discrete calculation steps for each packet: determining individual packet lengths, identifying header boundaries, calculating remaining space for padding, and selecting which packets receive padding. This segmentation transforms a complex global alignment problem into simpler local calculations that can be performed independently for each packet, reducing overall system complexity.
Solution Approach 2:
Each packet effectively determines its own padding requirements based on its intrinsic properties (length, header size, boundary position) rather than requiring centralized control and tracking of all packets. The system uses self-contained calculations within each packet context, eliminating the need for complex inter-packet coordination and boundary tracking mechanisms.
Data Source
AI summary
A transmission device is disclosed. The transmitting device comprises a processor for generating a packet comprising a header and a payload, on the basis of an input packet, and generating a frame comprising the generated packet, and a transmission unit for transmitting a signal generated on the basis of the frame. The processor inserts padding into at least one packet from among a plurality of packets included in the frame, on the basis of the number of packets included in the frame, the length of each input packet included in the frame, and the lengths of the packets. Here, the boundary of an input packet may be included in a packet into which padding is inserted.
