Remote Control Apparatus Variable Region Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing remote control systems for Multi Function Peripherals (MFPs) face inefficiencies when handling operation screens with variable regions, as they require transmitting and receiving large amounts of data during scroll operations, increasing data transmission and processing burdens.
Innovation Solution
A remote control apparatus and method that determines whether an operation screen includes a variable region, and if so, produces page display information to describe the screen's display mode, allowing for efficient transmission of this information instead of the entire image, reducing data transfer and processing demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the MFP transmits full operation screen images to the portable information device, then the display content is complete and accurate, but the data transmission amount increases significantly when scroll operations are required
Solution Approach 1:
The patent extracts only the necessary information elements from the full operation screen image - specifically the screen layout structure, variable region definitions, and display mode descriptions - and transmits them separately. This allows the portable device to reconstruct the screen locally without receiving complete image data, significantly reducing transmission volume while maintaining information completeness.
Solution Approach 2:
The patent changes the transmission parameter from complete image data to structured description data (page display information). By representing the operation screen as configurable parameters including variable region positions, display modes, and content placeholders, the system achieves efficient transmission that adapts to different scroll states without sending redundant full-screen images.
2Adaptability or versatility
If the MFP transmits multiple scrolled versions of the operation screen, then the portable information device can display scrollable content, but the data processing burden increases
Solution Approach 1:
The patent performs preliminary actions by pre-defining variable regions and their scrollable content structures in the transmitted page display information. The portable information device uses this pre-configured structure to locally generate scrolled views on demand, eliminating the need to receive and process multiple pre-rendered scroll positions from the MFP.
Solution Approach 2:
The patent enables the portable information device to create local copies and variations of the operation screen by interpreting the transmitted page display information. Instead of receiving multiple actual screen images, the portable device generates scrolled versions by copying and repositioning content within the defined variable regions, significantly reducing data processing requirements.

AI summary
A remote control apparatus includes a communication unit that communicates with a remote operation device and an apparatus-side controller. The apparatus-side controller includes an operation screen determining portion configured to determine an operation screen transmitted to the remote operation device, a page display information producing portion configured to produce page display information including a description to describe a display of an operation screen with a display mode of contents being capable of changing when the operation screen includes the contents of which the display mode is capable of changing in a predetermined variable region, a first transmitting portion configured to transmit the image of the operation screen to the remote operation device when the operation screen does not include the variable region, and a second transmitting portion configured to transmit the produced page display information to the remote operation device when the determined operation screen includes the variable region.
