Solution Overview

Problem

Conventional mobile equipment with television receiving functions cannot allow users to watch broadcasted television programs while displaying HTML contents or other application programs in whole screen, as starting such applications interrupts the television program viewing experience.

Innovation Solution

The mobile equipment includes a data storing section that sequentially stores image and voice data from digital broadcast waves, enabling users to continue watching television programs later even when starting applications that display in whole screen, by determining whether the link destination is HTML contents or broadcast contents and storing accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a whole-screen application program (e.g., Web browser) is started during television program viewing, then the user can access HTML contents or other application functions, but the television program viewing is interrupted and the user cannot watch the broadcasted content

Engineering Contradiction:

Improveapplication program execution capabilityVSAvoidtelevision program content

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system performs preliminary recording of the television program content in the data storing section before the whole-screen application is launched. This advance action ensures that the broadcast content is captured and stored, preventing any loss of information when the application switches to full-screen mode.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the television program content by recording it in the data storing section while the broadcast is being received. This copy allows the user to access and view the program content later without interfering with the application program execution, thus resolving the contradiction between application versatility and content preservation.

Inventive Principle:

Principle #26Copying

2Ease of operation

If the Web browser is started in whole screen to display HTML contents, then the user can access network information, but the user cannot simultaneously watch the television program broadcasted

Engineering Contradiction:

Improveinformation access capabilityVSAvoidtelevision program viewing continuity

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The system records the television program content in advance in the data storing section before the Web browser is launched. This preliminary recording action ensures that the program content is preserved and can be viewed continuously later, maintaining viewing duration even when the browser occupies the full screen.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The data storing section acts as an intermediary between the broadcast receiver and the display system. It stores the program content and allows it to be displayed later, serving as a buffer that decouples the application execution from the program viewing, thus enabling both information access and viewing continuity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If reception processing is stopped to allow whole-screen application display, then the application can run smoothly, but the television program reception is interrupted and content is lost

Engineering Contradiction:

Improveapplication program executionVSAvoidprogram reception continuity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary recording of the television program in the data storing section before stopping reception processing for application execution. This advance recording ensures that the program content is captured and stored reliably, preventing any loss of content even when reception is temporarily halted for application purposes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the program content by recording it while reception is active. This copy is stored in the data storing section and can be played back later, ensuring reliable preservation of the program content independent of reception status during application execution.

Inventive Principle:

Principle #26Copying

AI summary

A mobile equipment having television function, which renders a user to watch a television program, characterized in that said mobile equipment comprises: a data storing section for storing image data and voice data transmitted through digital broadcast wave; and a display control section for conducting a display with a predetermined timing for confirming whether said user hopes to watch the television continuously or said user hopes that the television program being watched is stored, in a case that start of an application program preventing said user from continuing to watch said television program is indicated by said user.
