Solution Overview

Problem

Digital broadcast receivers face challenges in efficiently displaying recorded programs, particularly with the increasing number of channels and overlapping broadcast times, leading to user inconvenience in selecting recorded content.

Innovation Solution

A digital broadcast receiver with a video recorder that records programs based on record-designation information for multiple channels and time zones, and a recorded-program list generator that displays only the recorded programs, optimizing the display to facilitate easy selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a program list is generated based on EPG data displaying all channels and time zones, then comprehensive program information is provided, but the display area is not effectively used and non-recorded programs occupy space

Engineering Contradiction:
Improvenumber of displayed programsVSAvoiddisplay area utilization
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent extracts only the recorded programs from the complete EPG data and displays them exclusively in the recorded-program list. This removes non-recorded programs from the display, effectively utilizing the display area for relevant content only, while maintaining comprehensive information about recorded programs across multiple channels and time zones.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If multiple channels and time zones are displayed in the program list, then comprehensive program coverage is achieved, but user effort to navigate and select recorded programs increases

Engineering Contradiction:
Improveprogram coverageVSAvoiduser selection effort
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the program list by recording designation, organizing recorded programs according to their record-designation information across multiple channels and time zones. This segmentation allows comprehensive program coverage while making selection easier through structured organization and visual distinction of recorded content.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different display characteristics to recorded programs versus non-recorded programs. Recorded programs are highlighted with distinct visual indicators and organized in a separate list structure, making them easily distinguishable and selectable, while non-recorded programs are excluded from the display entirely.

Inventive Principle:
Principle #3Local quality

3Stability of the object's composition

If recorded programs are displayed with the same format as EPG-based program lists, then consistency in display format is maintained, but recorded programs are not visually distinguished from non-recorded programs

Engineering Contradiction:
Improvedisplay format consistencyVSAvoidvisual distinction of recorded programs
Core Design Contradiction:
Stability of the object's compositionVSLoss of information

Solution Approach 1:

The patent applies distinct visual characteristics to recorded programs within the recorded-program list, using highlighting, different background colors, or special icons to visually distinguish recorded programs from non-recorded programs. This maintains overall display format consistency while providing clear visual differentiation for recorded content.

Inventive Principle:
Principle #3Local quality
