Information Terminal Playback Control for Display Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems face difficulties in setting playback information such as display order and duration for multiple images, as they primarily rely on display setting values like brightness and color mode, making it challenging to manage complex content data playback.
Innovation Solution
A display system comprising an information terminal and a display device that generates and transmits playback control information, including settings for display order, duration, and switching methods, allowing users to customize how content data is played back on the display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display setting information is transmitted to control display conditions, then ease of operation is improved, but device complexity increases due to additional information transmission and processing requirements
Solution Approach 1:
The information terminal serves multiple functions: it acts as both a content source and a playback control device. By integrating playback control information generation and transmission capabilities into the terminal, the system eliminates the need for separate control devices, thereby improving ease of operation while managing device complexity through functional consolidation.
2Productivity
If playback control information is generated based on number of selected content data, then productivity is improved through automation, but device complexity increases due to additional generation and processing functions
Solution Approach 1:
The information terminal generates playback control information in advance based on the number of selected content data items. This preliminary generation of control information automates the playback process, improving productivity by eliminating manual configuration during playback while the complexity is managed by performing the generation operation before content transmission.
3Ease of operation
If manual adjustment of playback settings is eliminated, then ease of operation is improved, but loss of information increases as custom playback configurations cannot be applied
Solution Approach 1:
The playback control information generation process is made dynamic by adapting it to the number of selected content data items. The system automatically adjusts playback settings based on the quantity of content selected, preserving relevant playback configuration information while eliminating the need for manual adjustment, thus balancing ease of operation with information retention.
Data Source
AI summary
A display system includes a display device and an information terminal able to communicate with the display device, the information terminal including a storage unit storing selected content data, a generation unit generating playback control information based on a number of the selected content data, the playback control information being used for controlling playback of the selected content data and including information indicating a storage location of the selected content data, and a transmission unit transmitting the playback control information to the display device, the display device including a display control unit controlling the playback of the selected content data based on the playback control information by referring to the information indicating the storage location of the selected content data.
