Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If channel bonding technology is used to transmit high-data-rate streams by splitting into multiple channels, then transmission capacity is improved, but stream processing complexity increases due to undefined details in current standards
Solution Approach 1:
The patent applies segmentation by dividing the high-data-rate input stream into multiple split streams, each assigned to different channels. The split unit separates the original stream into channel-specific segments that can be processed independently, then reconstructed at the receiver. This resolves the contradiction by maintaining high transmission capacity through multi-channel parallelism while reducing processing complexity through structured segmentation.
Solution Approach 2:
The patent implements preliminary action by generating signature information and CB signaling during the stream splitting phase at the transmitter. This pre-processing includes creating identification data that will be needed for reconstruction, so that when streams are received and need to be reassembled, the necessary information is already available. This reduces the complexity of stream processing at the receiver by having prepared all required data in advance.
2Productivity
If split streams are transmitted through multiple channels without signature information, then transmission efficiency is improved, but stream identification and reconstruction become difficult
Solution Approach 1:
The patent introduces signature information as an intermediary element that mediates between the split streams and the reconstruction process. This signature information, generated during stream splitting and attached to each channel's transmission, serves as an identifier that enables the receiver to recognize and properly reassemble the streams. This resolves the contradiction by maintaining transmission efficiency while preventing loss of identification information through the addition of this intermediary data structure.
Solution Approach 2:
The patent applies parameter changes by modifying the stream structure to include CB signaling and signature information as new parameters. These parameters are added during the stream splitting process and transmitted along with the split streams. By changing the parameter set of the transmitted data to include identification information, the system maintains transmission efficiency while ensuring that stream identification and reconstruction can proceed correctly.
3Manufacturing precision
If extensive reconstruction of original high-data-rate stream is performed, then stream accuracy is improved, but processing time increases
Solution Approach 1:
The patent implements feedback by using signature information and CB signaling as reference data that guides the reconstruction process. The receiver uses this pre-generated identification information to efficiently match and reassemble split streams without needing to perform extensive analysis. The feedback mechanism allows the system to achieve high reconstruction accuracy by comparing received streams against the signature information, significantly reducing processing time while maintaining precision.
Solution Approach 2:
The patent applies copying by creating and transmitting signature information that serves as a reference copy or fingerprint of the original stream characteristics. This signature is generated during stream splitting and transmitted with each channel's data. During reconstruction, this copied signature information enables rapid identification and verification of streams without requiring complete reconstruction and analysis of the entire original data, thus achieving high accuracy with reduced processing time.

AI summary
A data processing method is provided in which a transmission frame is received from a transmitting device. The transmission frame is based on a split stream for one of a plurality of channels and channel bonding signaling information. Further, the received transmission frame is processed. The channel bonding signaling information includes signature information that uniquely identifies the input stream, and the signature information is contained in a header of the transmission frame of a plurality of channels and transmits the split streams, for example.
