Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The channel bonding technique in digital broadcasting, such as DVB-S2x, faces challenges in properly processing high-data-rate streams due to unclear details, leading to potential failures in reconstructing the original stream at the receiving end.
Innovation Solution
A data processor and method that divide an input stream into multiple channels by distributing each packet to one channel and null packets to others, ensuring a predetermined density, allowing for proper stream reconstruction and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channel bonding technique is used to transmit high data rate streams, then data transmission capacity is improved, but stream processing reliability deteriorates due to unclear technique details
Solution Approach 1:
The input stream is segmented into multiple divided streams that are distributed across multiple channels. Each divided stream contains packets from the input stream at a predetermined density, achieved by distributing each packet to one channel and null packets to other channels. This segmentation enables high data rate transmission while maintaining processing reliability through standardized distribution rules.
2Area of stationary object
If packets are distributed to multiple channels, then transmission bandwidth is improved, but stream reconstruction accuracy deteriorates due to density variations
Solution Approach 1:
The distribution pattern varies locally across different channels while maintaining global uniformity. Each channel receives packets at a controlled density by distributing null packets to channels other than the selected channel, ensuring that reconstruction accuracy is maintained while utilizing full transmission bandwidth across all channels.
Solution Approach 2:
The packet density parameter is controlled and standardized across all channels through the distribution method. By distributing each input packet to one channel and null packets to others, the patent ensures predetermined density is maintained, enabling accurate stream reconstruction while maximizing bandwidth utilization.
3Adaptability or versatility
If channel bonding is implemented without standardized details, then transmission flexibility is improved, but processing consistency deteriorates
Solution Approach 1:
The patent establishes a universal distribution method that can be applied across different channel configurations and broadcast standards. The method of distributing each packet to one channel and null packets to others provides a consistent processing framework that works across multiple channels and maintains compatibility with existing standards like DVB-S2x.

AI summary
The present invention relates to a data processor and data processing method that facilitate properly processing a stream. An input stream is formed by a plurality of packets. Each of the packets of the input stream is distributed to one of a plurality of channels and null packets (NP) are distributed to the other channels. This divides the input stream into divided streams on a plurality of channels including the packets of the input stream at a predetermined density. The present invention can be used, for example, for a channel bonding (CB) technique in which an input stream is divided into a plurality of channels and transmitted.
