Description

  The present invention relates to a character input system that facilitates character input to a television receiver.

  Among character input systems for a television receiver, a remote controller dedicated to the television receiver has an advantage that it can be input from a remote place and is small. Further, the remote controller is provided with a plurality of character buttons, each of which has a character code corresponding to each button, and each time the button is pressed, the corresponding character code is acquired, and the television receiver Is displayed on the display. However, a conventional remote controller for a television receiver has to perform character input operation one character at a time. When inputting a plurality of characters, the number of times of pressing a button increases. There was a difficult drawback.

Therefore, a mobile terminal remote control device that enables character input on a mobile terminal device, not a remote controller dedicated to a television receiver, is known (see, for example, Patent Document 1).

  However, also in the conventional portable terminal remote control device, the user must operate a plurality of buttons when inputting a character string, which is troublesome. In addition, in the case of a TV receiver that comes with a function that allows you to search for the TV program you want to watch, you can search for TV programs by entering the user's favorite character and using that character as a keyword. Even in the search, in order to perform a more detailed search, more vocabulary that the user cannot imagine is required. To do so, the user had to look up the dictionary.

  The present invention has been made in view of the above circumstances. The character input system of the present invention is connected to the Internet with a mobile terminal device, extracts a character string from data received from the Internet, and is acquired by a display output processing unit. An object of the present invention is to provide a character input system that converts a character code into a character code, sends the character code to a television receiver, and enables display on the television receiver side.

A first character input system of the present invention is a character input system including a mobile terminal device and a television receiver,
The portable terminal device includes data processing means for receiving Internet information, input receiving means for receiving a character string extraction request from a user for the Internet information received by the data processing means, and the data processing means A character string extracting means for extracting the character string of the character string extraction request received by the input receiving means from the Internet information, and a first character string for converting the character string extracted by the character string extracting means to character string data. Data conversion means having the conversion table, and transmission means for transmitting the character string data converted by the data conversion means to the television receiver,
The television receiver, string conversion comprising a receiving means for the transmitting means receives the character string data transmitted, the second conversion table that converts the character string data received by the receiving means to a string Means, and display means for displaying the character string converted by the character string conversion means ,
The first conversion table and the second conversion table are similar conversion tables .

In the second character input system according to the present invention, in the configuration of the first character input system, the mobile terminal device further includes a recording medium control means for controlling reading / writing to the recording medium, and the recording medium control means, said character string is pre-Symbol string extraction unit extracted and writes to the recording medium.

In the third character input system of the present invention, in the configuration of the second character input system, when the input receiving unit receives a request for reading a character string from the recording medium , The recording medium control means reads character string information recorded by the recording medium.

  According to the character input system of the present invention, when the user inputs characters to the television receiver using the portable terminal device, the user can use the portable terminal device that can extract the character string from the Internet. The number of button operations is small, and a character string can be displayed on the television receiver, reducing labor.

First, in the case of the television receiver 101 with a function for searching for a television program that the user wants to watch, by inputting the user's favorite character, the character becomes a keyword and the user can search for the television program. This is a case of using a function that enables (hereinafter referred to as keyword search). The second is the case of the television receiver 101 that has a function for saving a favorite title in a recorded program, and it is possible to create a title by inputting a user's favorite character. is there. Since the input method is the same in both the former case and the latter case, here, the former is taken as an example, and the processing of the first embodiment of the present invention will be described below.

  When the user tries to perform a keyword search, first, the mobile terminal device 103 connects to the Internet using a communication control unit (not shown). When connected to the Internet, the received data AC is sent from the data processing unit 202 to the display output processing unit 204 and displayed on the display device 206. Here, it is assumed that “baseball” is displayed in a part of the text displayed on the display device 206. In order to extract the character string, the user starts a character string selection operation using the button input unit 104 of the mobile terminal device 103, and displays the output through the input processing unit 203 as the selected character string as the button input BC. The data is output to the processing unit 204. Then, a character string extraction completion operation is performed using the button input unit 104 of the mobile terminal device 103, the selected character string is confirmed, and the confirmed character string is transmitted to the communication signal via the signal conversion unit 205 and the signal output device 207. It is transmitted to the television receiver 101 as DC.

  The television receiver 101 receives the communication signal DC by the signal receiving unit 209 and converts the communication signal DC into a character string code that can be displayed by the input control unit 210. When converting, it is necessary that the television receiver 101 also has a conversion table similar to the character code conversion table of the mobile terminal device 103, and the conversion work is performed based on the character code conversion table. The converted character string is synthesized and displayed on the video from the tuner 211 on the display device 212. The user can perform a keyword search based on the combined character string “baseball”.
