Multimedia Communication Device Database Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia communication systems fail to display desired content and character strings on videophone terminals during call setup and do not provide effective data reproduction mechanisms.
Innovation Solution
A multimedia communication device connected to multiple terminals processes call signals by reading and transmitting content data and character strings from a database at prescribed timings, enabling appropriate reproduction on terminals during calls and after conversations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If content data are transmitted during call setup or after conversation, then data reproduction timing is improved, but system complexity increases due to database integration and timing control
Solution Approach 1:
The system performs preliminary actions by storing content data and character strings in a database before communication occurs. The multimedia communication device reads and transmits this pre-stored data at appropriate timings (during call setup or after conversation), eliminating the need for real-time data generation and ensuring timely reproduction without requiring complex real-time processing systems.
Solution Approach 2:
A database is introduced as an intermediary component between the multimedia communication device and terminals. The database stores content data and character strings, allowing the communication device to retrieve and transmit data at appropriate timings. This intermediary structure simplifies the overall system by centralizing data storage and management, reducing the complexity of distributed real-time data generation across multiple terminals.
2Loss of information
If character strings are inserted into image data, then information completeness is improved, but processing complexity increases
Solution Approach 1:
Character strings are read from the database in advance and inserted into image data before transmission to terminals. This preliminary processing ensures that all information (both visual and textual) is complete and ready for display, eliminating the need for complex real-time text overlay processing during active communication and reducing processing complexity.
3Productivity
If data are transmitted at prescribed timings, then communication effectiveness is improved, but control complexity increases
Solution Approach 1:
The system establishes prescribed timings for data transmission in advance - either during call setup or after conversation completion. The multimedia communication device controls data transmission according to these pre-determined timings, ensuring communication effectiveness by delivering content when terminals are ready to reproduce it, while avoiding complex adaptive timing control algorithms.

AI summary
At one of the timings: during a period between the moment when one of terminals which performs transmission calls out a communication partner and the moment of response and at the timing after the communication between the terminals is complete; content data is read out from a database and the read out content data is transmitted to the terminal.
