Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to commentary information which is added to the contents of a digital television broadcast and is not displayed on the screen, which are added in relation to the contents of a video being displayed or output audio.
Television receivers capable of storing and displaying data such as supplementary information or detailed information in real time, and then transmitting only the information selected by the viewer to a personal computer, mobile phone, etc. It is.

[0002]

2. Description of the Related Art In recent years, a television receiver has various functions, for example, a function of decoding and displaying text multiplex broadcast data in accordance with its own advanced functions and various needs of viewers. And those that can receive intertext broadcasts. Text multiplex broadcasting is to send text or graphic image information in the form of a digital signal by superimposing it on a video signal, for example, from news, weather forecast or stock price information added to ordinary television broadcasting. The viewer can select and view desired information. On the other hand, intertext broadcasting is a television broadcasting system in which a teletext broadcasting program is broadcast by using the time gap of television broadcasting waves with the aim of making effective use of the broadcasting waves. Two-way data service by data broadcasting using broadcast waves and communication using a telephone line, for example, television shopping, participation in quiz programs,
It offers services such as prize entry or interactive commercials.

[0003] Conventionally, as a television receiver for decoding and displaying the above-mentioned teletext data, among the data types in the teletext screen, the data set by the viewer in advance to be stored among the data types in the teletext screen. After extracting only the data of the type from the memory for the extracted data and storing it in the memory for the stored data, the data selected by the viewer as being necessary from the memory for the stored data is decoded, and is displayed as teletext display data. One that can be converted and displayed on a screen has been proposed (see JP-A-2000-78541). In this television receiver, unlike a conventional method in which data of a program registered in advance by a viewer is preferentially stored, data at a certain point in time of a program whose contents change dynamically is stored semipermanently. In addition, it is possible to obtain an effect that the memory capacity of the storage data memory is not wastefully consumed by unnecessary data.

On the other hand, as a television receiver capable of receiving intertext broadcasts, when a display image is displayed on a display after receiving intertext program data, the viewer is not allowed to view the display image being displayed. When the operation to save the display image to be referred to is performed, the data of the display image is written to the non-volatile memory and saved, and at any time after the end of the program, the viewer can perform the operation of reading the stored display image. Then, there has been proposed a device capable of converting display image data read from a nonvolatile memory into a video signal and then displaying the video signal on a display (see Japanese Patent Application Laid-Open No. 10-290438). In this television receiver, a viewer can view a display image of an intertext program that the viewer wants to refer to, for example, a display image of a map, a cooking recipe, or the like, at an arbitrary time after the end of the program. Further, since only the display image selected by the viewer is stored in the non-volatile memory, there is an advantage that unnecessary consumption of the memory capacity of the non-volatile memory can be suppressed.

[0005]

By the way, BS digital broadcasting has many features such as high image quality, multi-channel, and data broadcasting. Although long-awaited, experimental broadcasting has already been started from June of this year (2000), and it has been decided to start the main broadcasting from December of this year.

At the start of the digital broadcasting, the digital broadcasting is started in synchronization with the video signal of the television broadcasting program.
It has been considered to provide a service in which related information of the broadcast content is added and transmitted. For example, for a commercial broadcast, the advertiser's phone number, Internet address, company or store map, product data, etc.
In addition, for a baseball broadcast program, it is data such as information on players and results breaking news of other stadiums, and for a news program, it is data such as commentary information and supplementary information. Regarding these additional data, instead of displaying the information content on the screen at the same time as the broadcast of the program, a symbol mark is displayed to indicate that the additional data is sent in synchronization with the program being broadcast. It is considered to adopt a broadcast mode in which a small screen is displayed in the corner of the display by displaying it in the corner of the screen, leaving the viewer to select whether or not to refer to the additional data, and selecting only the data selected by the viewer. .

[0007] Since the additional data is related information of the broadcast content as described above, when the viewer stops storing the broadcast content, that is, during the broadcast of the program or immediately after the end of the broadcast of the program, the additional data is displayed. Most of the information contents can be expected to have the effect of the information when referred to. Therefore,
Regarding the additional data, when the viewer looks at the displayed symbol mark and operates a required operation button of the remote control transmitter, for example, the information content is displayed on a small screen in the corner of the display, and each time the operation is performed. A broadcast format in which each piece of information is sequentially displayed is considered.

[0008] However, when the above-mentioned broadcasting mode is adopted, when the viewer wants to save the information content being displayed, a troublesome work of writing the information content being displayed on paper or the like is required. Furthermore, if the viewer wants to edit and save the written information for each type, the troublesome operation of inputting the written information to a personal computer or registering a telephone number in a mobile phone is required. It must be made.

On the other hand, apart from the above-described embodiment, as for the additional data, the transmitted additional data is automatically stored and stored as in the prior art described above, and the viewer is stored at an arbitrary time. It is also conceivable to use a method of referring to the additional data on the screen display. However, in such a case, since information related to the broadcast content is viewed after a lapse of time since the end of the broadcast, the effect of obtaining the information cannot be expected so much, and a large-capacity hard disk or A problem arises that requires a disk medium such as a DVD-RAM.

In view of the above, the present invention has been made in view of the above-mentioned conventional problems, and allows data added as related information of broadcast contents to be referenced in real time, and a viewer among the additional data to be selected in real time. It is an object of the present invention to provide a television receiver which can transfer and save only registered data to a personal computer, a portable telephone, or the like.

[0011]

According to a first aspect of the present invention, there is provided a television receiver capable of receiving a digital broadcast, wherein the television receiver is provided with a synchronously added signal to a digital broadcast video signal. Data extraction means for extracting only additional data not displayed on the screen, a buffer memory for temporarily storing the additional data from the data extraction means, a storage memory for storing the additional data transferred from the buffer memory; A transmission unit for transmitting the additional data in the memory; and a control unit, wherein the control unit causes a display to display that the additional data is present in the program being broadcast, and allows the viewer to operate the additional data by the remote operation unit. When instructing the storage of, the additional data of the buffer memory is transferred to the storage memory and stored,
When the viewer instructs the display of additional data by the remote control means, each information included in the additional data stored in the storage memory is sequentially displayed on the display,
When the viewer instructs the transmission of the additional data by the remote control means, the remote control means has a control function of transmitting the additional data stored in the storage memory from the transmission means.

In this television receiver, when additional data, which is related information of a digital broadcast program, is synchronously transmitted to a broadcast program, the additional data is automatically taken into a buffer memory and temporarily stored. At the same time, since the presence of the additional data is displayed on the display, when the viewer instructs the storage of the additional data by the remote control means, the additional data can be transferred to the storage memory and stored. When the display is instructed, the additional data stored in the storage memory can be displayed on the display. Therefore, the viewer can refer to various information related to the program content in real time during the broadcast of the program. Further, when the viewer instructs the transmission of the additional data by the remote control means, the additional data stored in the storage memory can be transmitted. Therefore, the transmitted additional data is received and stored in, for example, a personal computer or a mobile phone. This eliminates the need to write the information content of the additional data on paper or the like, and also eliminates the need for input operation to a personal computer or the like, and allows the data stored in the personal computer or the like to be edited arbitrarily.

According to a second aspect of the present invention, in addition to the configuration described in the first aspect, the control unit further comprises:
Further, when the viewer instructs the selection of arbitrary information from among the information sequentially displayed on the display by the remote control means, a control function for storing only the selected information in the storage memory is provided. are doing.

According to this structure, the storage memory stores only the information selected by the viewer among the various information included in the additional data that the viewer desires to store.

The processing of the additional data can be easily and accurately remotely controlled for the television receiver body.

[0017]

Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a television receiver capable of receiving a digital broadcast according to an embodiment of the present invention.
In the figure, in order to facilitate understanding, a well-known configuration that is inevitably provided for practical use is omitted and illustrated as a simplified configuration.

That is, the television receiver body 1 has a receiving antenna 2 capable of receiving digital television broadcast waves, a well-known tuner, and an IF (intermediate frequency).
A broadcast receiving unit 3 including an amplifying unit and a detecting unit, an audio processing unit 4 including a well-known audio demodulating unit, an audio amplifying unit, an audio output unit, and the like, and a speaker 7 for outputting an audio signal of a television broadcast wave. A video processing unit 8 including a well-known video amplification unit, color demodulation unit, video output unit, etc., a display 9 such as a CRT or LCD for displaying video signals on the screen, and a CPU and a CPU for controlling each unit. A control unit 1 having a ROM or the like in which a control program to be stored is stored and controlling each unit of the television receiver body 1
0 and a remote control signal receiving unit 11 that receives a remote control signal from the remote control transmitter 19 and outputs the signal to the control unit 10. The above configuration is almost the same as the existing configuration provided in the conventional television receiver.

Further, the television receiver body 1 includes:
A data extracting unit 12 for extracting only the additional data from the output of the broadcast receiving unit 3 based on a command from the control unit 10; a buffer memory 13 for temporarily storing the additional data from the data extracting unit 12; A storage memory 14 to which the additional data read and transferred from the buffer memory 13 is written, a data transmission unit 17 for transmitting data read from the storage memory 14 by the control unit 10 from a transmission antenna 18, and a control unit Display of symbol mark, additional data, etc. according to command of 10
And a display control unit 15 for displaying on the display. In addition,
Since the additional data processed by the above configuration is a digital signal, the additional data may be transmitted by infrared rays instead of the means for transmitting radio waves from the transmitting antenna 18. The transmitted additional data is stored after being received by the personal computer 20 or the mobile phone 21.

The remote controller transmitter 19 is not shown in the figure because of its well-known configuration, but in addition to the existing various operation buttons for analog channel selection, various operation buttons for digital channel selection and the like. Operation buttons for data broadcast reception are provided, and further, as shown in FIG. 4, a data storage operation button 22, a data display operation button 23, a data selection operation button 24, and a selection button for additional data processing. An operation button 27 for determination and an operation button 28 for data transmission are provided. The various operation buttons 22, 23, 24, 27, and 28 shown in FIG.
Without being provided in the remote control transmitter 19, the remote control transmitter 1
9 may be provided on a separate operation key panel (not shown) dedicated to additional data.

The above-mentioned television receiver is provided with various operation buttons 22, 23, 24,
When the buttons 27 and 28 are not pressed, the image signal of the television broadcast wave is displayed on the display 9 by a well-known signal processing, similarly to a normal television receiver.
At the same time, an audio signal is output from the speaker 7. Since this signal processing is very well known, a description thereof will be omitted. Next, control processing of additional data of a broadcast program in the television receiver 1 will be described with reference to FIGS. 2 and 3 which respectively show a flowchart of the first half and a latter half of the control processing. The two types of connection points A and B shown in FIGS. 2 and 3 are connected to each other.

Referring to FIGS. 2 and 3, the television receiver body 1 receives a broadcast upon turning on the power (step S1).
Then, the control unit 10 starts control of signal processing for the additional data transmitted along with the broadcast program, and constantly determines whether the additional data is transmitted in synchronization with the broadcast program (step S10). S2). Then, the control unit 10 determines that additional data exists in the broadcast program (step S2).
Then, it instructs the data extraction unit 12 to extract additional data. Thereby, the data extracting unit 12 extracts only the additional data from the broadcast receiving unit 3 and
3 and the buffer memory 13 temporarily stores the input additional data (step S3).

The control unit 10 gives a command to temporarily store the above-mentioned additional data in the buffer memory 13 and, at the same time, gives a command to the display control unit 15 to display a symbol indicating that the additional data exists in the program being broadcast. The mark is displayed at the corner of the display 9 (step S4). In addition, instead of displaying the above-mentioned symbol mark, the display 9 displays a small-screen content that inquires the viewer whether to save the additional data, for example, a content such as “Do you want to save the additional data?” Is also good.

Next, the control unit 10 controls the buffer memory 1
Then, it is determined whether or not an instruction to save the temporarily stored additional data has been given by the viewer (step S5), and this determination processing is continued until a predetermined time has elapsed (step S6). This predetermined time is preferably set to, for example, a time from the start of the broadcast of the program to the end of a certain time (for example, 10 seconds) after the end of the broadcast. here,
If the viewer does not press the data storage operation button 22 of the remote control transmitter 19 until the predetermined time elapses because the viewer is not interested in the program being broadcast, the control unit 10 Control is performed to erase the contents stored in the buffer memory 13 (step S7), and the process returns to step S2 to repeat the same processing as described above.

On the other hand, if the viewer sees a display inquiring whether the symbol mark or the additional data is stored, and presses the data storage operation button 22 of the remote control transmitter 19, the remote control signal is transmitted to the remote control signal receiving section. After being received at 11, it is sent to the control unit 10. This allows
The control unit 10 determines that the storage of the additional data has been instructed (step S5), and controls to read out the additional data stored in the buffer memory 13, transfer it to the storage memory 14, and store it (step S8). . At this time, the stored contents of the buffer memory 13 are deleted when the additional data is read.

After that, the control unit 10 controls the display control unit 1
5 is displayed on a small screen of the display 9 to ask the viewer whether to display the additional data stored in the storage memory 14 (step S5).
9). For example, the display 9 displays a content such as “Do you want to display saved data?”. continue,
The control unit 10 determines whether or not an instruction to display the additional data stored in the storage memory 14 has been given by the viewer (step S10). Here, when the viewer presses the data display operation button 24 of the remote control transmitter 19 in order to refer to the information added to the program being broadcast, the control unit 10 It is determined that the instruction is an instruction to display additional data based on the input of the remote control signal from the unit 11 (step S10), and the storage memory 1
4, the additional data being stored is captured, and as shown in FIG. 5, a menu M indicating the information content included in the captured additional data is displayed on the display 9 in a small screen (step S11). In the menu M, the title of information content is displayed for each data type number arranged in the vertical direction on the left side.

Here, the viewer refers to the information content of the additional data based on the menu M displayed on the small screen, and performs an operation of selecting the information to be stored. That is, the viewer can select the cursor buttons 24 above and below the data selection operation button 24.
a, 24b to sequentially designate the data type numbers corresponding to the titles of interest in the menu M, and operate the data display operation button 23 for each designation.
Is pressed. As a result, the information content of the specified title is sequentially displayed in the small screen display area shown in FIG. 5 on the display 9 instead of the menu M (step S11). This allows the viewer to refer to each piece of information included in the additional data in real time by referring to the program contents.

Further, the viewer presses the selection determination operation button 27 each time the information to be stored exists in the information sequentially displayed on the small screen. The control unit 10 starts from the time when the menu M is displayed on the small screen.
A determination is started as to whether any of the information included in the additional data has been selected (step S12), and only the information selected by the viewer by pressing the selection determination operation button 27 is stored in the storage memory. 14 (step S1
3). Thus, the viewer can reliably save the information content of the additional data without writing it on paper or the like, and can select and save only desired information.

On the other hand, the control unit 10 continues to determine whether to display the additional data stored in the storage memory 14 (step S10) until a predetermined time has elapsed (step S14). When it is determined that the predetermined time has elapsed without a display instruction from the viewer (step S14), the additional data is stored in the storage memory 14 as it is (step S15). This is the case, for example, when the viewer does not need to refer to the information of the additional data with the content of the program being broadcast, but wants to save it. For example, when a commercial is being broadcast, viewers can save data such as the advertiser's phone number, Internet address, company and store maps, and merchandise, and refer to it at any time after the program ends. For example, when it is considered to be sufficient.

The control section 10 continues to determine whether or not the information in the additional data has been selected (step S12) until a predetermined time has elapsed (step S16).
When it is determined that the predetermined time has elapsed without any information being selected by the viewer (step S16), the additional data is directly stored in the storage memory 14 (step S15). This means that, for example, when a baseball broadcast program is being broadcast, information such as a result report of another stadium or a result of a player in a game of another stadium may be displayed on a small screen and confirmed in real time. Since it is not necessary to save the data, the viewer can operate the data display operation button 22.
Is operated, and the operation button 27 is not operated once. Alternatively, the above processing
This is executed when the viewer has not pressed the selection determination operation button 27 without showing any interest in any of the displayed information.

Subsequently, the control unit 10 controls the storage memory 14
Is displayed on the display 9 in a small screen (step S17). For example, the display 9 displays a small screen such as “Do you want to send the data being saved?”. After that, the control unit 10 determines whether or not a data transmission instruction has been given from the viewer (step S1).
8) If it is determined that the instruction has been given, the storage data 14
Is read from the transmission antenna 18 via the data transmission unit 17 (step S1).
9). The transmitted data is received and stored in the personal computer 20, for example. Information such as a telephone number is registered and stored in the mobile phone 21. This allows the viewer to save only necessary information among the information included in the additional data in the personal computer 20 or the mobile phone 21 without performing an input operation. Can be edited accordingly.

The control section 10 continues to determine whether to transmit the additional data (step S18) until a predetermined time has elapsed (step S20), and gives an instruction to transmit the additional data from the viewer. When it is determined that the predetermined time has elapsed without being performed (step S20), the additional data is stored in the storage memory 14 as it is (step S21). After that, the control unit 10 determines whether or not the broadcast is being received (step S22). If the broadcast is being received, the control unit 10 returns to step S2, repeats the same control processing as described above, When it is determined that the broadcast receiver has not been received because the power of the main unit 1 of the television receiver has been turned off (step S22), control is performed so that the contents stored in the storage memory 14 are collectively erased (step S23). Thus, a memory having a small memory capacity can be used as the storage memory 14.

[0033]

As described above, according to the television receiver of the present invention, when additional data, which is information related to a digital broadcast program, is transmitted in synchronization with a digital broadcast program,
After the additional data is stored and stored in the storage memory by the viewer's remote control means, the additional data being stored in the storage memory can be displayed on the display. Can be referred to in real time during program broadcasting. Further, when the viewer instructs the transmission of the additional data by the remote control means, the additional data stored in the storage memory can be transmitted. Therefore, the transmitted additional data is received and stored in, for example, a personal computer or a mobile phone. This eliminates the need to write the information content of the additional data on paper or the like, and also eliminates the need for input operation to a personal computer or the like, and allows the data stored in the personal computer or the like to be edited arbitrarily.
