[Industrial application fields]
The present invention relates to a broadcast receiving apparatus equipped with a character input function.
[0002]
[Prior art]
A broadcast receiver (memo TV) equipped with a character input function is known. As a character input method in the character input function, a multi-tap method is adopted as in the key operation of a mobile phone or the like. For example, when “A”, “B”, and “C” are assigned in this order to the two numeric keys, the user presses the 2 key three times when desiring to input “C”.
[0003]
[Problems to be solved by the invention]
However, since a plurality of characters are assigned to one numeric key in a fixed order, it is necessary to press the key an equal number of times in order of assignment in order to obtain a desired character. For this reason, many key operations are required to input a message in the conventional broadcast receiving apparatus.
[0004]
In view of the above circumstances, an object of the present invention is to provide a broadcast receiving apparatus capable of reducing the number of key operations for character input and reducing the time required for message input.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problem, the broadcast receiving apparatus of the present invention has a plurality of characters assigned to some keys of the remote control transmitter, and signals output from the remote control transmitter by the operation of the keys are displayed as characters. In a broadcast receiving device equipped with a character input function that is handled as an input signal, the output order of a plurality of characters assigned to each key is unfixed, and characters are assigned in the descending order of probability as the first character or as the character that has already been confirmed. It is characterized by comprising means for outputting, means for displaying the outputted character on the screen, and means for storing the confirmed character string in the memory as a message.
[0006]
With the above configuration, if a plurality of characters assigned to each key are the first character, the first character is output in order of the probability, and if it is a character that follows an already confirmed character, the already confirmed character is output. Are output in descending order of probability, so that the number of key operations for character input is reduced and the message input is required compared to the conventional configuration in which the key is pressed the same number of times in order of assignment to obtain the desired character. Time can be shortened.
[0007]
In the broadcast receiving apparatus of the present invention, a plurality of characters are respectively assigned to some keys of the remote control transmitter, and a character input that treats a signal output from the remote control transmitter by operating the key as a character input signal. A broadcast receiving apparatus having a function is characterized by comprising means for extracting character information from a broadcast wave on which character information is multiplexed, and means for storing the extracted character information in a memory as a message.
[0008]
With the above configuration, the character information acquired from the broadcast wave can be used as a message, so the number of key operations for character input can be reduced and the time required for message input can be shortened.
[0009]
In the broadcast receiving apparatus using the character information, the character information stored in the memory may be displayed on the screen, and the character information may be corrected by the character input function. With such a configuration, it is possible not only to use the text information acquired from the broadcast wave as it is as a message, but also to have a message with a desired correction.
[0010]
In the broadcast receiving apparatus using the character information, the output order of a plurality of characters assigned to each key is unfixed, and the characters are output in descending order of probability as the first character or as a character that has already been confirmed. It should be configured.
[0011]
In any one of the above broadcast receiving apparatuses, the message stored in the memory is output on the screen when the power is turned on for the first time after the message is created or when the power is turned on for the first time to the predetermined number of times. May be.
[0012]
Any one of the above broadcast receiving apparatuses may include a transmission unit that transmits information using a line, and the message may be transmitted by the transmission unit.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 7. Here, a case where a user views an analog broadcast is illustrated. FIG. 1 is a block diagram showing a television receiver of this embodiment, FIG. 2 is a plan view showing the appearance of a remote control transmitter, and FIG. 3 shows characters assigned to each numeric keypad of the remote control transmitter 10. FIG. 4 is a flowchart showing the processing contents when the message input function is used, FIG. 5 is an explanatory diagram of the message input screen, and FIG. 6 shows the processing contents when the receiving device is activated. FIG. 7 is an explanatory diagram of an input screen when the message FAX function is used.
[0014]
The antenna 1 converts the received broadcast wave into an electric signal and supplies it to the tuner 2. The tuner 2 mixes the desired channel signal and the local oscillation signal to generate an intermediate frequency signal. The detection circuit 3 extracts a composite color television signal (a luminance signal, a carrier color signal, and a synchronization signal) by detecting an intermediate frequency video signal. The video signal processing circuit 4 generates a color subcarrier, uses this to demodulate the color difference signal from the carrier color signal, and performs processing such as generating a color signal (R, G, B) from this color difference signal. The drive circuit 8 amplifies the color signal and the luminance signal to a size necessary for driving the picture tube 9, extracts the sync signal from the color TV signal, and divides it into a vertical sync signal and a horizontal sync signal. Give to 9.
[0015]
The teletext information extraction unit 5 performs a process of extracting teletext information (for example, superimposed on the 6th to 22th scanning lines) included in the color television signal. The teletext decoder 6 decodes the extracted teletext information, generates a character display signal (RGB signal), supplies it to the mixing circuit 12, and supplies control bits, station name information, and the like to the CPU 13.
[0016]
The mixing circuit 12 adds the character display signal output from the teletext decoder 6 and the character display signal output from the character generator 7 (numbers of channel numbers, etc.) to the video signal output from the video signal processing circuit 4.
[0017]
The remote control transmitter 10 is a transmitter for sending a command to the television receiver. When a key provided on the remote control transmitter 10 is operated, signal light (remote control signal) indicating a command corresponding to the key is transmitted from a light emitting unit (not shown). The remote control light receiver 11 receives the signal light, converts it into an electric signal, and gives it to the CPU 13.
[0018]
The remote control transmitter 10 has an appearance as shown in FIG. 2, for example, and a plurality of characters are assigned to the numeric keys 0 to 9, respectively. For example, as shown in FIG. 3, “A”, “B”, “C”, “2” for 2 numeric keys, and “D”, “E”, “F”, “3” for 3 numeric keys. , 4 or 5 characters (alphabet, numbers, symbols) are assigned to each numeric keypad. In the character input mode, for example, when the number 2 key is pressed, the CPU 13 recognizes the signal as a character input signal indicating one of the characters “A”, “B”, “C”, and “2”. . If the character displayed by pressing the numeric keypad is not the character desired by the user, another character can be selected and displayed from among the characters assigned to the numeric keypad by pressing the NEXT key. it can.
[0019]
In the character input mode, the CHUP key / CHDOWN key / VOL + key / VOL-key function as an UP key / DOWN key / RIGHT key / LEFT key, respectively, and are used for cursor movement and scrolling. The MESSAGE key is used for switching between the character input mode and the normal mode, and the CLEAR key is used for erasing the message storage contents stored in the nonvolatile memory 14 and erasing the characters on the message input screen.
[0020]
The SAVE key is used when a sentence (determined character string) created on the message input screen is stored in the nonvolatile memory 14. In this embodiment, the SAVE key is also used when teletext information displayed on the screen by teletext is stored in the nonvolatile memory 14 as message contents. The FAX key is used when switching to the FAX number / character input mode and as a transmission execution key. It should be noted that a display such as “character input mode” or “FAX” may be performed on the screen, and the mode may be switched when the display unit is selected by the user.
[0021]
The non-volatile memory (for example, EEPROM) 14 stores the above-described message contents and the like.
[0022]
The CPU 13 performs overall control in the television receiver, and in particular, executes message input control as control according to the present invention. Here, a program and database for character selection exist in a ROM (not shown) that provides software to the CPU 13. As the database, it is possible to use a database that holds probability information that a certain character (including symbols and numbers) appears at a certain position in the character. For example, in order of decreasing probability as a character following the four characters “ANTL”. Provides information that “Y”>“W”>“X”>“Z”> “9” among “W”, “X”, “Y”, “Z”, and “9”. It only has to be. In this embodiment, Letter Wise Software (see US Pat. No. 6,219,731) is used as a program and database for character selection.
[0023]
FIG. 4 is a flowchart showing the processing contents of the message input function performed by the CPU 13, and FIG. 5 is an explanatory diagram of the message input screen. When the MESSAGE key (see FIG. 2) of the remote control transmitter 10 is pressed, the receiving apparatus shifts to the character input mode, and the CPU 13 determines whether or not there is a message storage content in the nonvolatile memory 14 (step S1). If there is a message storage content, the CPU 13 reads the message storage content stored in the nonvolatile memory 14 and displays it on the screen (step S2). If there is no message storage content, a message input screen in a non-input state (a state in which nothing is displayed on the screen) is displayed (step S3).
[0024]
When the numeric key is pressed (YES in step S4), the CPU 13 performs input character determination (step S5). In the input character determination processing, for example, four or five characters assigned to the numeric keypad are referred to in descending order of probability by referring to database information based on characters (including spaces) from the current cursor position to the previous four characters. select. In the first character output, the character with the highest probability is displayed on the message input screen (step S6). When the NEXT key is pressed (YES in step S7), the character determined to have the next highest probability is selected from the characters assigned to the key (step S8), and the display character on the message display screen is changed. (Step S9).
[0025]
When the CLEAR key is pressed (YES in step S10), the CPU 13 erases the message storage contents stored in the nonvolatile memory 14 (step S11) and erases the characters displayed on the message input screen. (Step S12). If the SAVE key is pressed (YES in step S13), the message content displayed on the message input screen is stored in the nonvolatile memory 14 (step S14).
[0026]
Further, the CPU 13 determines whether or not the MESSAGE key has been pressed (step S15), and if not, returns to step S4 and continues the processing. On the other hand, if the MESSAGE key is pressed, it is determined whether or not the characters on the message input screen have been updated (step S16). If not updated, the mode shifts to the normal mode. Displays, for example, “Do you really want to exit” as a message for confirming the transition to the normal mode as shown in FIG. 5C (step S17). It is determined whether or not the MESSAGE key is pressed again within 5 seconds after the MESSAGE key is pressed (step S18). If the MESSAGE key is pressed, the process shifts to the normal mode. If not, the process returns to step S4. Continue processing.
[0027]
Hereinafter, a specific processing example of message input by the message input function described above will be described.
[0028]
(1) When the user presses the number 6 key when the number 6 key is pressed in the “_” state (non-input state: see FIG. 5 (a)), the CPU 13 determines the four characters before the cursor as the input character. At this time, since there is no character input before the cursor, the CPU 13 refers to the database under the condition that there are four blanks, and “M” “N” assigned to the numeric “6” key. ”,“ O ”, and“ 6 ”. In the above case, the input character is the first character of the word, and the CPU 13 is provided with information that “O”, “M”, “N”, and “6” are in descending order of probability as the first character. Therefore, “O” is first displayed on the screen. If “O” is not a character desired by the user, pressing the NEXT key converts the characters in the order of “M”, “N”, and “6” determined in the input character determination process and displays them. It will be.
[0029]
(2) When a continuation is input from the state of “We can constantl_” (see FIG. 5B)
When the user presses the number 9 key, the CPU 13 performs input character determination processing using “antl” that is the four characters before the cursor, and the characters “W”, “X”, and “Y” assigned to the number 9 key. Rank "Z" and "9". In this case, the order in which the probabilities of the characters following “antl” are high is determined as “Y”, “W”, “X”, “Z”, and “9”, so the CPU 13 displays the first “Y” on the screen. Display. When “Y” is not a desired character, when the NEXT key is pressed, the characters are converted and displayed in the order of “W”, “X”, “Z”, and “9” determined in the input character determination process. become.
[0030]
(3) When correcting input contents (from “PEN” to “PIN”)
The LEFT key of the remote control transmitter 10 is pressed, the cursor is moved to the position of the character to be corrected, and “P E N” is set. Here, when the user presses the number 4 key including the desired “I”, since “E” is not included in the 4 key, “EN” is deleted, and the first selected in the input character determination processing is deleted. The second character is displayed at the cursor position. If the first character is not desired, the user selects “I” using the NEXT key. Next, in order to display “N”, the numeral 6 key is pressed. The CPU 13 performs a process of displaying the character “N” first by the input character determination process.
[0031]
Note that, for example, if the 6 key is operated twice in a state where there is no input character, two characters “on” are input. That is, “o” is displayed in the first operation of the 6 key, and if this character is not desired, the user operates the NEXT key, but the 6 key is operated without operating the NEXT key. Since the second operation has been performed, the CPU 13 determines that “o” is a confirmed character (desired character), determines that “n” is likely to continue as a character following “o”, and the character “on” The input is executed with few key operations such as two times. As described above, the combination with the NEXT key enables more efficient character input.
[0032]
FIG. 6 is a flowchart showing the processing contents when the receiving apparatus is turned on. When the power of the receiving device is turned on, the CPU 13 determines whether or not the message storage content is stored in the nonvolatile memory 14 (step S21). When there is no message storage content, the mode is changed to the normal mode and broadcast is received. On the other hand, if there is a message storage content, the CPU 13 determines whether the message storage content has been displayed twice (step S22). If it has been displayed twice, the mode shifts to the normal mode, and if not, the message storage content is displayed on the message display screen (step S23). When the MESSAGE key is pressed (step S24), the mode is shifted to the normal mode. In the above description, the message storage content is displayed up to two times. However, the number of times of display is not limited to this, and the user may set it arbitrarily.
[0033]
In the above-described example, the message input function is used and the message created from the beginning by the user is stored in the nonvolatile memory 14, but the teletext information received by the receiving device may be stored as the message content. . The teletext information can be stored in the nonvolatile memory 14 when the user presses the SAVE key of the remote control transmitter 10 when the teletext information is displayed on the screen. Here, for example, when a recipe is displayed as teletext information while viewing a cooking program, the recipe is stored in the nonvolatile memory 14 by pressing the SAVE key.
[0034]
As an example of inputting teletext information as message storage contents, assume that a mother who is going out leaves a message asking the child to prepare dinner for the receiver. When the mother presses the MESSAGE key of the remote control transmitter 10, a message input screen on which the previously saved curry recipe is displayed is displayed. The mother uses the message input function to input a message such as “Return around 8 o'clock. Make a curry according to this recipe.” To the front of the recipe portion using the remote control transmitter 10. In addition, the contents of the recipe can be corrected using a message input function. In this correction, the above-described “PEN” is changed to “PIN”. Thus, for example, when there is an expression difficult for a child to understand in a curry recipe, that part can be corrected. Of course, even in this correction, the correction can be performed with few key operations by the input character determination using the database. By pressing the SAVE key, the message with the recipe is stored in the nonvolatile memory 14. When the child who has returned home turns on the power of the receiving device, the CPU 13 reads the message storage contents from the nonvolatile memory 14 and displays the message with the recipe on the message display screen.
[0035]
Moreover, it is good also as a structure which can fax the produced message using the communication function part 15. FIG. When the user presses the FAX key (see FIG. 2) provided on the remote control transmitter 10, the user switches to the FAX number / character input mode and enters a FAX number input waiting state. FIG. 7 is an explanatory diagram of an input screen when the message FAX function is used. As shown in FIG. 7, the cursor is positioned at the first digit of the FAX number input area 21 on the initial screen. At this time, the user inputs a FAX number using the remote control transmitter 10, but the numeric key is treated as an original numeric key in the FAX number input area 21. If the area code is not required, the RIGHT key may be pressed to move the cursor to a predetermined position. When the FAX number is input, the cursor moves to the message input area 22. Here, the user inputs a message using the above-described message input function. To save the message, press the SAVE key. To delete the message, press the CLEAR key.
[0036]
In order to send a FAX, the FAX key may be pressed after the SAVE key is pressed. During the FAX transmission operation, for example, a message such as “On Process” is displayed at the bottom of the screen, and when the transmission is completed, a message such as “SENT” is displayed so that the user can check the transmission state. . Further, when it is desired to interrupt transmission during FAX transmission, the transmission may be interrupted by pressing a power key, for example. Similarly to the message input function, the FAX number / character input mode is switched to the normal mode by pressing the MESSAGE key while a message is being output. In addition, when data is present in the nonvolatile memory 14 when the FAX key is pressed in a normal television reception state, the stored contents are displayed.
[0037]
In the above example, the FAX number is input and the FAX is transmitted. However, instead of the FAX number, an E-MAIL address may be input to transmit the E-MAIL. In the remote control transmitter 10 described above, alphabets such as “ABC” are associated with the numeric keys, but Japanese characters such as “Aiu ...” and other characters used in other countries are associated. It is good. Further, although an analog broadcast receiving apparatus is shown, the present invention can also be applied to a digital broadcast receiving apparatus. In this case, the character information can be obtained by data broadcasting, for example.
[0038]
【The invention's effect】
As described above, with the broadcast receiving device of the present invention, the number of key operations for character input can be reduced and the time required for message input can be shortened in character input to the receiving device. The input message can also be transmitted by facsimile or the like.
