Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing broadcast recording devices record entire programs, including those the user does not wish to record, leading to unnecessary processes.

Innovation Solution

A broadcast reception device that acquires program identification and storage information, transmits it to a server, and outputs broadcast content, allowing selective recording and playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the broadcast reception device records the entirety of the currently-viewing broadcast program, then the user can record from the head position, but unnecessary programs are also recorded leading to wasted storage space and processing time

Engineering Contradiction:

Improveability to record from head positionVSAvoidstorage space waste

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The system performs preliminary actions by storing program identification information and storage destination information in a recording-content storage area before actual recording occurs. This allows the device to prepare recording parameters in advance, enabling selective recording of only desired portions of broadcast programs while maintaining the capability to record from head position when needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The recording process is segmented into information acquisition, information storage, and selective execution phases. The program identification information and storage destination information are separated and stored independently, allowing the device to selectively retrieve and process only the necessary recording content rather than recording entire programs indiscriminately.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the broadcast reception device records the entirety of the currently-viewing broadcast program, then the user can record from the head position, but unnecessary processes are performed reducing efficiency

Engineering Contradiction:

Improveability to record from head positionVSAvoidrecording process efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The recording process becomes dynamic and adaptable based on user needs. The device can selectively execute recording based on retrieved information, allowing flexibility between recording entire programs from head position or recording only specific segments, thereby optimizing processing efficiency according to actual requirements.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If program identification information and storage destination information are stored and transmitted to server devices, then selective recording is enabled, but device complexity increases

Engineering Contradiction:

Improveselective recording capabilityVSAvoidsystem structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The recording-content storage area serves multiple functions: storing program identification information, storing storage destination information, and enabling both selective recording and playback operations. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing device complexity while providing versatile selective recording capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses an intermediary approach by storing only essential identification and destination information locally rather than storing complete program content or complex control structures. This intermediary information acts as a key that enables selective access to full program content from server devices, simplifying the local device structure while maintaining adaptability.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A broadcast reception device includes: a program recording execution unit that stores, into a recording-content storage area, program identification information for identifying a broadcast program, and storage-destination information for specifying a server device storing the broadcast program; a reception function execution unit that transmits the program identification information and the program storage-destination information to the server device specified from the program storage-destination information; and an output unit that outputs sound information and image information on the broadcast program transmitted from the server device.
