Solution Overview

Problem

Conventional automatic recording/reproducing apparatuses record all reserved programs, leading to unnecessary storage of old news or weather forecast programs, wasting time and storage capacity.

Innovation Solution

An automatic recording/reproducing method and apparatus that registers group recording reservations, records only the latest program corresponding to these reservations, and allows users to reproduce and output the last recorded program upon user operation, deleting older recordings to conserve storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all reserved programs are recorded, then complete program archive is maintained, but storage capacity is wasted and user time is consumed by old irrelevant programs

Engineering Contradiction:
Improveprogram archive completenessVSAvoidstorage capacity utilization
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements automatic deletion of old recorded programs from specified categories (news, weather forecasts) while preserving the latest program. The control unit monitors recorded programs and automatically removes outdated ones, freeing storage capacity while maintaining the most relevant content for user viewing.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The patent extracts and identifies specific program categories (news, weather forecasts) from the total recorded programs. By separating these time-sensitive categories from other programs, the system applies selective deletion only to relevant categories, preserving archive completeness for important content while optimizing storage for categories where only the latest program matters.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If all reserved programs are recorded, then no program is missed, but user time is wasted reviewing old programs

Engineering Contradiction:
Improveprogram coverageVSAvoiduser viewing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system automatically discards old programs in time-sensitive categories (news, weather) and recovers user time by preventing unnecessary viewing. The control unit identifies and deletes these programs, ensuring users only encounter the latest relevant content, thereby eliminating time waste from reviewing outdated information.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The system performs self-service by automatically managing program retention without user intervention. The control unit autonomously determines which programs to keep and which to delete based on category and timestamp, freeing users from manual management and time-wasting browsing of irrelevant old programs.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If group recording reservation is implemented, then storage is optimized, but device complexity increases

Engineering Contradiction:
Improvestorage efficiencyVSAvoidrecording control logic
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The control unit is designed with multi-functionality, handling both traditional recording control and the new automatic deletion function within a single component. This universal approach manages different program categories (news, weather, other) using unified logic, reducing overall system complexity despite the added functionality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Recording reservation information of a plurality of programs is grouped and at least the latest program among the programs recorded on the basis of the reservation information is left on a recording medium. Therefore, a program information registration unit to register a plurality of items of recording reservation information as groups and a reserved program recording control unit to record the reserved programs onto the recording medium and leave at least the latest program among the programs recorded on the recording medium to delete the others on the basis of the reservation information.
