Multicast Reply System Using Job ID History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication systems require complex user operations to initiate a reply multicast transmission, as users must manually input receivers and transform data formats for different communication protocols.
Innovation Solution
The system includes an image processing apparatus with a multicast transmission section that embeds identification information in emails, allowing for automatic extraction and processing of history information to facilitate easy reply multicast transmissions by designating receivers based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual input operations are used to command reply multicast transmission, then the system can execute reply multicast under different communication protocols, but the user operation complexity increases
Solution Approach 1:
The system performs preliminary actions by automatically extracting receiver information from the original multicast transmission and storing it in advance. When a reply is needed, the pre-stored information is readily available, eliminating the need for users to manually input receiver details and significantly reducing operational complexity.
Solution Approach 2:
The system serves itself by automatically managing the reply multicast process. The image processing apparatus autonomously extracts identification information, retrieves stored receiver data, and executes the reply multicast transmission without requiring user intervention for data entry, making the system self-sufficient in handling reply operations.
2Ease of operation
If automatic extraction of identification information is implemented, then the process of commanding reply multicast transmission is simplified, but the device complexity increases
Solution Approach 1:
The system extracts only the necessary identification information (such as message IDs or headers) from the received multicast transmission. By selectively extracting only the critical data elements needed for reply processing rather than handling entire messages, the system simplifies the extraction process while maintaining functionality.
Solution Approach 2:
The system introduces an intermediary mechanism in the form of stored identification information that bridges the received multicast message and the reply transmission process. This intermediary layer allows the system to match incoming messages with stored receiver information without requiring complex real-time processing, thereby reducing device complexity.

AI summary
A data communication system, an image processing apparatus, a program and a data communication method which permit a user to command a reply multicast transmission in reply to a multicast transmission with easy operations. In executing a multicast transmission of first image data, the image processing apparatus sends a job ID together with the first image data to a computer which is one of the receivers of the multicast transmission. Concurrently, the image processing apparatus stores the job ID and the receivers of the multicast transmission in relative to each other as history information. When the computer replies to the multicast transmission, the computer sends a reply e-mail including second image data and the job ID to the image processing apparatus. Then, the image processing apparatus extracts the job ID from the reply e-mail and searches the history information for receivers of the multicast transmission identified by the job ID. Thereafter, in accordance with the searched receivers, the image processing apparatus designates receivers of a reply multicast transmission and sends the second image data to the designated receivers.
