Broadcast Program Guide Interface with Dynamic Page Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadcast program selection systems face limitations in providing high visibility for viewers as the number of broadcast programs increases, leading to reduced display area sizes and poor visibility of program content.
Innovation Solution
A transmission/reception system that categorizes broadcast image data into groups and generates program guide screen data, switching between different display frames at predetermined intervals, allowing for high visibility by maintaining consistent display frame sizes and using cursor graphics for easy selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of broadcast programs to be displayed increases, then the quantity of information provided increases, but the display area size for each program is reduced leading to poor visibility
Solution Approach 1:
The program guide screen is segmented into multiple pages, with each page displaying a limited number of programs (e.g., 16 programs per page). This segmentation allows the system to handle a large total number of programs while maintaining adequate display area for each program on individual pages.
Solution Approach 2:
The patent introduces a temporal dimension by automatically switching between multiple program guide pages at predetermined time intervals. This transforms the static single-page display into a dynamic multi-page presentation, allowing more programs to be displayed across different time slots while maintaining consistent display area size on each page.
2Quantity of substance
If the number of broadcast programs to be displayed increases, then the quantity of information provided increases, but the visibility and ease of selection for each program deteriorates
Solution Approach 1:
The system performs periodic automatic switching between program guide pages at predetermined time intervals. This periodic action ensures that each page receives adequate display time for viewer recognition and selection, maintaining ease of operation even when many programs are available across multiple pages.
Solution Approach 2:
The system provides self-service by automatically managing page transitions without requiring manual page navigation from the user. The automatic switching at predetermined intervals allows the system to serve the user's information needs while maintaining simple operation through implicit timing-based navigation.

AI summary
A transmission/reception system includes a transmitter and a receiver. The transmitter includes a first circuit that: acquires plural pieces of broadcast image data; categorizes the broadcast image data at least into first and second groups; generates program guide screen data that switches between first and second program guide screen data; generates temporal information about the predetermined time interval and broadcast program identification information; and transmits the screen data and the information. The receiver includes a second circuit that: receives the data and the information; outputs the program guide screen data; detects, when any one of the display frames is selected by a user operation, broadcast program identification information contained in the first or second program guide screen data; and performs control in such a way that the broadcast image data corresponding to the detected broadcast program identification information are output from the image data output device.
