Program Table Display Method for Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses struggle to accurately display the program that is currently being played back among multiple recorded programs, especially when playing back recorded content continuously without user designation.
Innovation Solution
An electronic apparatus and program table display method that utilizes a past program table and time shift key to visually distinguish and switch between recorded programs based on their recording times, allowing for exact display and playback of the currently playing program, even when switching between channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple digital broadcast waves are received and recorded simultaneously by multiple tuners, then the recording capacity and functionality are improved, but it becomes difficult to accurately display which program is currently being played back among the recorded programs
Solution Approach 1:
The patent introduces a time dimension to the program table display by adding time shift indicators that show the recording time difference between currently broadcast programs and recorded programs. This dimensional addition allows the system to display multiple recorded programs while clearly indicating which one is currently being played back, resolving the information loss problem caused by simultaneous multi-channel recording.
Solution Approach 2:
The patent uses a time shift indicator as an intermediary element between the program table and the playback status. This indicator acts as a mediator that translates the complex multi-channel recording state into a visually distinguishable representation, allowing users to understand which recorded program is currently playing without confusion.
2Extent of automation
If recorded programs are played back continuously in accordance with recording times, then automated playback is improved, but the ability to indicate the currently playing program on the electronic program table deteriorates
Solution Approach 1:
The patent employs visual differentiation (analogous to color changes) by displaying time shift indicators in distinct visual forms. The indicator changes its visual representation based on the time shift value, allowing users to quickly identify the currently playing program among continuously played back recorded programs, thereby maintaining measurement precision despite automated playback.
Solution Approach 2:
The time shift indicator dynamically updates to reflect the current playback status. As programs are played back continuously, the indicator automatically adjusts to show the new current program, maintaining accurate program identification without requiring manual intervention while preserving measurement precision.
3Quantity of substance
If a program table is created based on service information data about recorded programs, then information completeness is improved, but the clarity of indicating the currently playing program deteriorates
Solution Approach 1:
The patent segments the program table information by introducing a distinct time shift indicator component separate from the basic program information. This segmentation allows the program table to maintain complete program information while adding a separate visual element that clearly indicates the currently playing program, making detection easier without losing information completeness.

AI summary
A recording/playback control module is configured to record programs of a video signal received by a broadcast receiving module together with EPG information. A program table generating module is configured to generate a program table where the recorded programs are listed in a form of a table whose axes designate recording time and channel respectively, based on the EPG information played back by the recording/playback control module. The recording/playback control module is configured to play back programs in sequential order with respect to a channel in the program table. When the program table generating module receives an instruction to display the program table while the recording/playback control module plays back a given program, the program table generating module highlights the given program in the program table.
