Description

Specific screen storage device of internet TV

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to Internet television, and more particularly, to a specific screen storage device for an Internet TV, which allows a screen to be stored in an appropriate state during viewing.

Increasing interest in communications generally includes devices with communications capabilities, i.e., PC communications televisions that incorporate some of the functionality of televisions for viewing regular channel programs in PCs, and some features of PCs for Internet access in televisions. Internet TV which let you appear is appearing.

In addition, the interactive Internet TV using the Internet TV network will play an important role as an optional media that will revolutionize the home culture of the coming 21st century.

This interactive Internet TV enables not only Video On Demand, but Game On Demand, Education On Demand, and Home Shopping.

Hereinafter, the Internet TV of the prior art will be described with reference to the accompanying drawings.

1 is a configuration diagram showing a schematic configuration of a conventional Internet television.

An Internet TV having an Internet connection function in a general television receiver firstly receives a general video signal (or image information on the Internet through a satellite repeater) and a specific signal among signals received through the antenna 1. A tuner unit 2 for selectively outputting a signal, a PIF 3 for detecting a video signal selected and output from the tuner unit 2, and an SIF (4) for detecting an audio signal selected and output from the tuner unit 2; ), And audio and video signals output from the PIF 3 and SIF 4 or from an external device 13 (Internet connection is possible through this external device input / output terminal. For example, using a modem or the like). A / V switching unit 5 for selectively outputting audio and video signals of the video, and a video processor 7 for processing the video or audio information selectively output from the A / V switching unit 5, audio processor 8, video above First and second amplifiers 9 and 10 for amplifying and outputting an audio signal and a video signal output from the processor 7 and the audio processor 8, and an image signal output from the first amplifier 9. CRT 12 for displaying a user to view, a speaker 11 for outputting the audio signal output from the second amplifying unit 10 to be heard from the outside, and a microcomputer 6 for controlling the whole system. Etc.)

In such an Internet TV, a user may view general video information or video information on the Internet through a selection signal input means (such as a channel selection switch or a remote wireless control device).

Currently, a systematic standard for searching and selecting and receiving image information on the Internet through TV is currently set, but the most likely one is likely to be mainstream through a TV that is spread in homes rather than a PC. .

In such a prior art Internet TV, its function is limited and its applicability is inferior in the current media system which is multifunctional. In addition, since the current Internet TV is a connection between media blocks having different operating systems, there is a problem in that the user does not have a function of storing and redisplaying a specific screen image in terms of video.

The present invention has been made to solve the problems of the Internet TV of the prior art, to provide a specific screen storage device of the Internet TV to be suitable for the multimedia era by maintaining a specific screen image in an appropriate state during viewing. The purpose is.

The specific screen storage device of the Internet TV of the present invention, which allows a specific screen to be stored in an appropriate state while watching, is provided with an antenna / tuner unit for receiving / tuning general video signals and video information on the Internet, and tuned video and audio signals. By A / V switching unit that selects and outputs audio and video signals from PIF and SIF to be detected, and audio and video signals from an external device that can be connected to the Internet through a modem. A second memory for detecting and storing the audio signal of the SIF, a designated voice storage unit for storing and outputting specific audio information by a user's selection, a comparator for comparing the audio information of the second memory and the specified voice storage unit, And a memory controller for storing and outputting image information of the PIF in the first memory when the comparison result is matched. The specific screen storage method of the Internet TV may include searching for and storing the received audio signal when the screen is switched to a specific screen storage mode, and comparing the searched audio signal with a stored audio signal specified by a user's selection. Storing the specific image information including the corresponding audio signal when the searched audio signal matches the specified audio signal in the determination step; and continuing the searched stored audio signal and the stored audio signal specified by the user's selection. And comparing the matched with each other, and if the searched audio signal does not match the audio signal selected by the user, stopping the storing of the specific image information.

Hereinafter, a specific screen storage device of the Internet TV of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a block diagram of an Internet television having a specific screen storage function according to the present invention, and FIG. 3 is a flowchart illustrating an operation of a specific screen storage device of the Internet TV according to the present invention.
