Method and device for storing information of Internet TV

The present invention provides a stable information storage by maintaining the power line of the Internet module even when power off by a user's mistake when storing information provided on the Internet in a memory in a TV with an Internet function. The present invention relates to a method and apparatus for storing information on an Internet television.

The Internet has a concept of A Network of Networks, which interconnect each computer network in the world, and each computer network is connected by Transmission Control Protocol / Internet Protocol (TCP / IP).

TCP / IP is a method for computer network communication, and all hosts are mandated by the TCP / IP protocol to establish a computer network that can communicate with all computers connected to the network regardless of the type. We changed the software to apply it.

With this protocol, an example of communication network construction between users over the Internet (here, a user, strictly speaking, a search program, that is, a device or a computer that can perform communication by a browser) is schematically illustrated in FIG.

First, the user 100 runs an internal search program that allows the user 100 to view information through an Internet service for communication with another Internet user or information provider through the Internet, and then the state of the modem and the flow of data. The modem 120 is driven by the communication connection program 110 that controls the control.

In this case, the modem 120 connects the Internet service provider 130 and the user through a predetermined communication line (generally, a telephone line).

The Internet service provider 130 refers to a company that allows an individual or a company to access the Internet. In general, the Internet service provider 130 may be connected to the Internet through a computer communication service company, so it is regarded as an Internet service provider.

The Internet service information company 130 makes a connection with the Internet 140 through a dedicated line such as a high speed optical cable when a plurality of connected users request an Internet connection.

Such Internet services allow users to access and acquire a large number of up-to-date information in various fields, and even provide individual communication of users, and the use of the Internet using computers is rapidly spreading.

In addition to attempting to communicate with the Internet through such a computer-based method, users can easily connect to the Internet and access to a lot of information without feeling the objection of the computer. Internet TV is a commercial product equipped with a module for carrying out this process.

In other words, the Internet television is equipped with a small computer for communication with the Internet in the existing television to enable communication with the Internet by only a television.

The module for communication with the Internet mounted in the television includes a flash memory 230 in which a search program for communication with the Internet is written, as shown in FIG. CPI (200) for processing data to be transmitted and received by a search program written in the flash memory 230 in accordance with a key command; A key input unit 240 for applying a key command to the key input unit 240; An image signal processor 250 for encoding the data processed by the CPI 200 into an NTSC signal for displaying on a television screen; An audio signal processor 260 for converting an audio signal of data processed by the CPI 200 into a signal suitable for output to a speaker of a television; A modem 220 for connecting the transmission and reception data input and output to and from the CPI 200 with a communication line; The RAM 220 is configured to temporarily store data for transmission and reception with the CPI 210 through the modem 220.

On the other hand, the RAM 210 should be stored in advance the phone number for access to the Internet service provider, this phone number can be changed at any time by the user's needs.

In addition, the key input unit 240 is usually composed of a keyboard having the form of a wireless remote control, the key input unit 240 is provided with a power key that can be turned on / off the power of the television.

The operation process thereof is described in detail as follows.

When a user wants to communicate with the Internet and applies a predetermined command through a key input unit 240, that is, a key installed in a remote controller, a television main body, or a keyboard, the CPI 200 detects the key command and flash memory 230. ) Will load the search program.

At this time, the flash memory 230 stores a search program written by a television manufacturer, that is, a browser, and is equipped with a program for performing related routines of the Internet communication module system.

In addition, the CPI 200 enables the modem 220 to access the Internet service company by dialing a phone number of a predetermined Internet service provider in the RAM 210.

CPI 200, which reads a search program written in the flash memory 230, can communicate with the Internet based on this. First, image information of initial menu information for searching for information desired by a user is displayed. Output to the processing unit 250.

The video signal processing unit 250 encodes data of the picture information output from the CPI 200 into a proper NTSC signal for displaying on a screen of a television and outputs it to the screen.

The user must select a site to be accessed through the key input unit 240 while viewing the picture information displayed on the screen.

Here, a site is a space that contains information and means a collection of logically separated information.

When the user selects a site to be connected, the CPI 200 transmits its information to the Internet service provider through the modem 210, and accesses the corresponding site of the Internet through a dedicated line of the Internet service provider.

When the connection is made to the corresponding site of the Internet and the data in the corresponding site is received by the modem 220 through the Internet service provider, the received data is temporarily stored in the RAM 210, and the CPI 200 uses the RAM ( The data stored in 210 is received and processed by a search program stored in the flash memory 230 so that the user can see it (in the case of voice data).

When the data is processed into a user's viewable (or audible) data, the data is applied to the video signal processor 250 and converted into an NTS signal to be displayed on a television screen.

In addition, in the case of voice data, it is applied to the voice signal processor 260 and processed in a form suitable for output to a speaker.

Thus, the user can obtain the desired information while viewing the displayed information thereof.

However, such an Internet television has a key input unit, that is, a wireless keyboard with a power on / off key, and when the power off key is pressed by a user's mistake while storing information in the flash memory, the TV module is turned off and the internet module is turned off. The power is turned off.

This prevents the flash memory from storing the complete information that you want to save. If you download a new version of the search program from a particular site on the Internet via a modem and want to upgrade, the write operation of the downloaded search program to the flash memory is written. If the power is turned off in the middle, the complete search program cannot be upgraded, and there is a problem that a malfunction of the system occurs in a later communication with the Internet.

In addition, if the power is turned off while downloading information from a specific site of the Internet and storing it in a flash memory, there is a problem that the information cannot be read later.

Therefore, in view of the above problem, the present invention detects the input state of the power off key while downloading and storing specific information from the Internet, and maintains the power line of the Internet module for the information storage time even when the power off key is input. It is an object of the present invention to provide a method and apparatus for storing information on an Internet television that allows complete information storage.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The information storage method and apparatus for Internet television according to the present invention will be described in detail with reference to the accompanying drawings.

First, when a user presses the power key 390 provided on the keyboard 340 to apply a power-on command to the CPI 370 of the television system side, the CPI 370 detects the command to supply the power 380. By turning on, the television system and the Internet module are powered.

Subsequently, when a user applies a command through the keyboard 340 to access the Internet, the CPI 300 of the Internet module reads a search program stored in the memory 330 and uses the image signal processor 350 to display the television system. It will be displayed on the screen.

When the user inputs a site on the Internet to be accessed by the displayed search program through the keyboard 340, the CPI 340 on the Internet module side accesses the site on the Internet desired by the user through the modem 320. (ST10).

In addition, when the user selects and downloads specific information after accessing the Internet site, the information is downloaded through the modem 320 and temporarily stored in the RAM 310 (ST310).

At this time, in the process up to the above operation, the CPI 300 on the Internet module side is not currently in use of the flash memory 330, so that it is not storing information, that is, a signal of logic '0' CPI on the television system side. 370 is applied.

The CPI 370 on the television system side then controls the power supply 380 to continue to apply power to the Internet module.

The temporarily stored information in the RAM 310 is stored in the memory 330. At this time, the memory 330 uses a flash memory capable of reading and writing (ST40).

Meanwhile, during the process of storing information in the memory 330, the signal that information is being stored in the current memory 330 from the CPI 300 on the Internet module side, that is, the signal of logic '1' Application to 370 recognizes that the CPI 370 on the television system side is in the information storage state.

At this time, if a power-off command is applied to the CPI on the television system side through the power key 390 due to a mistake of the user, information is stored in the memory 330 on the Internet module side. The sipe oil 370 of the control unit 380 controls the power supply unit 380 to turn off only the power of the television system and keep the power line of the Internet module (ST60).

As a result, the Internet module may be continuously supplied with power to continuously store information stored in the RAM 310 in the memory 330.

After that, when it is determined by the CPI 300 of the Internet module that all the information stored in the RAM 310 is stored in the memory 330, the CPI 300 receives a signal indicating the end of information storage, that is, a signal of logic '0'. It is applied to the CFI oil 370 on the television system side.

Then, the CPI 370 of the television system controls the power supply unit 380 to turn off the power applied to the Internet module so that all information downloaded through the Internet is completely stored and then turned off.
