Multichannel Data Processing with Selective Element Discarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multichannel data transmission processes, network channel interruptions lead to increased time costs for confirming data receipt and potential retransmission, affecting data processing efficiency due to the need to wait for incomplete data elements.
Innovation Solution
A method where receiving and transmitting devices determine the discardability of data elements based on their dependence on other elements and influence on post-processing results, allowing for direct transmission of subsequent elements and discarding incomplete ones during network channel switching.

Engineering Contradiction Analysis
1Speed
If data elements are transmitted through multiple network channels to improve transmission efficiency, then data transmission speed is improved, but time cost increases due to channel interruptions and retransmission requirements
Solution Approach 1:
The patent changes the parameter of data element discardability based on delivery type classification. By determining whether a data element is discardable or non-discardable based on its delivery type, the system can make intelligent decisions about retransmission, reducing time costs while maintaining transmission efficiency.
Solution Approach 2:
The patent applies different quality standards to different data elements based on their delivery types. Discardable data elements (type 1) are handled differently from non-discardable data elements (type 2), allowing the system to optimize retransmission strategies locally for each element type rather than applying a uniform approach.
2Reliability
If the receiver waits for incomplete data elements to ensure data completeness, then data reliability is improved, but data processing efficiency deteriorates due to waiting time
Solution Approach 1:
The patent introduces a delivery type parameter that changes the handling approach for different data elements. By classifying data elements as discardable or non-discardable based on their delivery type, the system can process discardable elements immediately without waiting for retransmission, while maintaining reliability for non-discardable elements.
Solution Approach 2:
The patent segments data elements into different categories based on delivery types. This segmentation allows the receiver to process different types of data elements through different pathways: discardable elements can be processed or discarded immediately, while non-discardable elements follow traditional retransmission protocols, thus improving overall processing efficiency without sacrificing reliability.
3Reliability
If all data elements are retransmitted upon channel interruption to ensure completeness, then data reliability is improved, but loss of time increases due to unnecessary retransmission of already received elements
Solution Approach 1:
The patent uses delivery type as a parameter to determine retransmission necessity. By checking the delivery type of each data element, the system can identify discardable elements that do not require retransmission, thereby reducing retransmission time while maintaining reliability for critical non-discardable elements.
Solution Approach 2:
The patent implements a discarding mechanism for data elements marked as discardable (delivery type 1). When channel interruption occurs, the receiver can discard these elements without requesting retransmission, while still maintaining data completeness for non-discardable elements. This selective discarding reduces unnecessary retransmission time.

AI summary
A data processing method is performed by a receiving device. The method includes: receiving, through at least two network channels, data elements transmitted by a transmitting device, the data elements comprising delivery serial numbers; obtaining subsequent data elements of the received nth data element on the basis of the delivery serial numbers; and determining, when the subsequent data elements comprise a target data element, that a delivery result of the nth data element is discarded, a state of the target data element being a complete state, the target data element having a same data type as the data type of the nth data element, the target data element being an independent data element, the data type being determined on the basis of an effect of the data element, and a dependence degree of the independent data element on other data elements during post-processing being less than a specified degree.
