Transmission Management Apparatus for Group Display Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices used as client terminals for cloud services, such as televisions and video conference terminals, lack a suitable user interface for character input, making it difficult for users to perform operations, especially without keyboards or limited remote controls.
Innovation Solution
A transmission management apparatus and system that manages display information across multiple terminals, allowing for group identification and dynamic display updates, enabling simplified user operations by transmitting and receiving group identification information and change instructions to update display content on connected terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional devices (televisions, video conference terminals) are used as client terminals, then cloud services can be accessed, but user operations become difficult due to lack of suitable input interfaces
Solution Approach 1:
A user terminal device (smartphone, tablet, or PC) serves as an intermediary between the user and the transmission terminal. The user terminal displays operation screens that guide users through character input and other operations, while the transmission terminal executes these operations without requiring direct user interaction with complex interfaces. This mediator approach resolves the contradiction by enabling cloud service access on simple devices while providing ease of operation through guided interfaces on the user terminal.
2Device complexity
If devices without keyboards or with limited keys are used, then device simplicity is maintained, but character input capability deteriorates
Solution Approach 1:
The user terminal device acts as an intermediary that handles the complex character input operations. It displays operation screens with virtual keyboards, text prediction, and other input assistance features, while the transmission terminal remains simple and executes only the operational commands. This allows the transmission terminal to maintain simplicity while the user terminal provides sophisticated input capabilities through its display and processing functions.
Solution Approach 2:
The system divides functional responsibilities into two segments: the user terminal handles user interface and character input operations, while the transmission terminal handles transmission execution. This segmentation allows each component to be optimized independently - the transmission terminal remains simple and dedicated to its core function, while the user terminal provides complex input capabilities through its display and processing resources.
3Adaptability or versatility
If display information is managed individually on each terminal, then terminal autonomy is maintained, but centralized management capability is lost
Solution Approach 1:
The transmission management apparatus provides universal management functionality that can operate across multiple transmission terminals. It stores display information in association with terminal identification information and transmits this information to terminals as needed. This universal approach enables centralized management while maintaining terminal autonomy, as each terminal can independently receive and display information without requiring complex local management systems.

AI summary
An apparatus includes a storage unit configured to store therein, in association with one another, group identification information for identifying groups to which transmission terminals each belong, transmission terminal identification information for identifying the terminals belonging to the respective groups, and display information to be displayed on the transmission terminals belonging to the groups. The apparatus also includes an acquiring unit configured to acquire the group identification information of a certain group and a change instruction for the display information; a changing unit configured to change the display information associated with the group identification information in the storage unit based on the change instruction; and a transmitting unit configured to transmit the display information associated with the certain group in the storage unit and changed to the terminal identified by the transmission terminal identification information associated with the group identification information of the certain group in the storage unit.
