Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television broadcast receiver, and more particularly, to a control signal superimposed on a broadcast signal, a display method of a program using the control signal, and a television receiver. The present invention relates to a broadcast receiver provided with a control method for a video / audio output signal output to a recording device or the like.

[0002]

2. Description of the Related Art Conventionally, in a broadcasting station of a television broadcast, when the end time of a currently broadcast program is extended for various reasons, the start time of the next broadcast program, that is, the updated time is updated. As a method for notifying the viewer of the program start time, an announcer verbally announces the program start time or employs a technique of superimposing on the TV screen of the viewer. .

[0003] For example, when it becomes clear that a baseball broadcast that is currently being broadcasted is in an overtime and does not fit into the originally scheduled broadcast time frame, the baseball broadcast will be broadcasted before and after the originally scheduled broadcast end time. On the viewer's television screen, the scheduled start time of the next broadcast program is displayed. In addition, if the current live broadcast of baseball can be continuously moved to another channel, the channel is superimposed on the TV screen, or an announcer verbally announces to the viewer. Means were widely adopted.

[0004] Even if a normal program (normal program) is interrupted due to an emergency report such as a disaster or the like, the same as described above may be performed around the time when the originally scheduled normal program starts. Announcement by way was widely practiced. Further, in digital broadcasting by a broadcasting satellite started from December 2000 (hereinafter referred to as “BS digital broadcasting”), it is called an electronic program guide (EPG) using program arrangement information sent from a broadcasting station. Service is being performed.

[0005] In this electronic program guide, a radio
The program name and broadcast start time etc. are presented on the TV screen like a TV column, and the viewer selects the desired program from the displayed programs with the cursor,
The channel providing this program has been automatically selected. The electronic program guide is updated from the broadcasting station as needed, so that it is possible to cope with a change in the broadcasting time or the like.

[0006] In addition, since a temporary channel is notified by a signal called EIT in the program arrangement information, it is possible to temporarily cope with the extension of the program. Furthermore, in BS digital broadcasting, a transmission multiplex control signal called a TMCC signal is superimposed on a broadcast wave signal, and by controlling an activation control signal bit in the signal, a viewer's signal can be transmitted during an emergency report such as a disaster. It is also possible to automatically start up the television receiver and forcibly change the channel of the television receiver during reception.

[0007]

By the way, in the conventional television broadcasting, in the case of analog broadcasting, an extension of a program is announced by using a signal superimposed on a broadcast wave or a video recording time is extended. I couldn't do that.
Further, when the channel of the program to be extended is changed to another channel on the way (switched by the broadcast station), the channel change is appropriately performed based on a preset audience preference. There was a problem that control, that is, it was not possible to control the receiver by reflecting the viewer's preference.

[0008] Further, in the case where provision of a temporary program or display indicating that the program is to be extended is superimposed directly on the screen, if the viewer is recording the program, However, since the superimposed display is also recorded at the same time, there is a problem that when the recorded program is viewed at a later date, the superimposed display becomes an obstacle. Was.

In the BS digital broadcasting, a special channel is notified using the EIT of the program arrangement information, and video recording on the special channel on which the broadcast of the extended program is taken over is continued. A control operation to be continued is possible. However, this control operation is performed only between BS digital broadcast channels, and the channel switching between BS digital broadcast and existing analog broadcast (for example, terrestrial broadcast) cannot be set. Had.

[0010] In the method using the EIT,
The viewer can recognize that the temporary channel is currently being broadcast, but the means to send directly to the EIT what the content is and what its urgency is is Not available, viewers will not be able to,
There was a problem that it became possible to know such information.

Further, in the above-mentioned method using the EIT, the area to be broadcasted, the degree of urgency, and the priority are not reported, so that the viewer can watch a special channel on the basis of conditions set in advance, Alternatively, there has been a problem that it is not possible to take selective means for avoiding viewing.

The method using the EIT is described in EP
The text information for explaining the program content is transmitted on the G screen, but it is a general description only, for example, text information specialized only for a temporary channel for the purpose of superimposing on the screen is transmitted. There was a problem that it was not possible.

The present invention has been made in view of the above problems in the conventional television broadcasting system, and
In the event that a program extension or emergency news program occurs due to a channel change, make sure to notify the viewer of that fact,
An object of the present invention is to provide a broadcast receiver capable of continuously recording a current program.

[0014]

Means for Solving the Problems The present invention has the following structure to solve the above-mentioned problems. That is, a broadcast receiver receives a broadcast wave of a television broadcast, converts the received broadcast signal into a received signal, converts the received signal into a video / audio signal, and outputs the received signal. Control signal separating means for separating signals, output condition setting means for allowing a viewer to preset output conditions and output format when displaying or recording a program to be extended or a program to be temporarily interrupted; Output condition determining means for comparing the control signal with the output condition set by the output condition setting means, and program output means for displaying and recording a program based on the output format based on the determination result by the output condition determining means. And a configuration having:

[0015] With this configuration, the broadcast receiver separates the control signal contained in the broadcast wave through the control signal separating means, and separates the extended or temporarily interrupted program. An output condition and an output format at the time of display / recording are set in advance by a viewer via output condition setting means, and the separated control signal and the set output condition are output through output condition determination means. The program can be displayed and recorded by the program output means on the basis of the output format based on the result of the comparison and judgment. Therefore, when the program is extended or the temporary program is suddenly organized, the viewer can set in advance. The display form of the program can be changed according to the condition.

The program output means may switch the receiving channel so that the program is not interrupted, based on the result of comparing and determining the separated control signal and the output condition set by the output condition setting means. The program can be displayed and recorded based on the output format.

With this configuration, for example, a receiver of a viewer living in the target area designated under the above conditions can view and record a temporary program or a new program on the original channel. In the receivers of the viewers living in other areas, the display indicating that a temporary program is being performed appears on the screen, the channel is switched to the bypass channel, and the original program and the original extended program continue without delay For example, the convenience can be improved according to the regionality of the viewer.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a block diagram showing an overall configuration of a broadcast receiver according to a first embodiment.

And a recording output terminal (program output means) for an external recording device.

It should be noted that the broadcast receiver 10 may have a configuration in which the display section 8 is not provided and only the recording output terminal as shown in FIG. 1 is used instead, that is, a configuration called a tuner. Also, antenna 1 and tuners 2 and 3
Is compatible with both analog broadcasting (here, terrestrial broadcasting) and BS digital broadcasting.

Hereinafter, the function of the broadcast receiver 10 according to the present embodiment will be described with reference to FIG. The present invention relates to a program presentation method of a television receiver in a case where a program is extended from a scheduled program schedule, an emergency report in a disaster or the like, or an output signal control method of a television receiver. Based on a program extension / temporary program control signal superimposed on a broadcast wave and a condition set in the receiver in advance by a viewer (user), the screen display of the television receiver is changed or switched, and the television receiver is switched. The video output signal can be switched.

Further, according to the present invention, when a program is extended or a temporary program such as an emergency report is broadcast, a program extension / temporary program control signal is received from a broadcasting station, and the extension of the program and notification of the emergency report can be easily performed. It is configured to be able to do. With this configuration, the viewer can easily know the occurrence of the program extension or the presence of the emergency news program,
Further, even in such a situation, the current program can be continuously recorded.

The program extension / temporary program control signal includes a channel name / channel number on which the extension program / temporary program is being broadcast, a channel name / channel number as a detour destination, a target main area, a priority, It is assumed that the information includes a program flag indicating whether the program is a program extension or a special program, and character data that can be freely described by the broadcaster for displaying the program extension or the special program on a receiver.

A program extension / temporary program control signal sent from a broadcasting station and information preset in the receiver by the viewer (that is, area data where the receiver is installed, priority data relating to the area, In order to solve the above-mentioned problem, the extended program or the temporary program is displayed most appropriately when the program is extended or the special program is broadcast. Further, by performing signal processing on the video recording output of the receiver in the same manner, the extended program can be continuously recorded, and the recording channel can be automatically changed at an appropriate timing.

Further, for example, when a temporary program of BS digital broadcasting is performed by terrestrial broadcasting, a table for associating terrestrial broadcasting channel names with the channel numbers is provided in the receiver. By checking the information recorded in this table against the channel name included in the program extension / temporary program control signal, the tuner unit can be adapted from BS digital broadcasting to terrestrial broadcasting. For example, upon reception, it is possible to automatically switch from a BS digital broadcast channel to a terrestrial broadcast channel.

The broadcast wave transmitted to the broadcast receiver 10 according to the present embodiment includes a program extension and a normal program signal.
A signal called a temporary program control signal is superimposed. However, the program extension / temporary program control signal is superimposed only when a program extension occurs or when a temporary program exists.

FIG. 2 is a configuration diagram showing a configuration of a program extension / temporary program control signal. In the configuration of the program extension / temporary program control signal shown in FIG. 2, a header (packet header) indicating that the signal is a program extension / temporary program control signal and a data portion are provided.

The data section is controlled by the program extension / temporary program control signal, a target channel name, a channel number, a detour destination channel name, a channel number, which is a target of the program extension or special program. Target areas and
A priority indicating the display handling priority of a temporary program on a television screen, a program identification flag for identifying a distinction between a program extension and a temporary program, and a broadcasting business for the purpose of being displayed on a television screen or the like. And any character data sent from the user. However, this character data may not be transmitted when it is determined that the broadcaster is unnecessary.

The operation of broadcast receiver 10 according to the present embodiment will be described below with reference to FIGS. Tuner 2,
Reference numeral 3 indicates that when a temporary program or a program extension is performed, the original channel (the temporary program or the new program is received) and the bypassed channel (the original program or the original extended program are received). ) Are displayed on the screen at the same time. In a normal composition state in which a temporary program is not interrupted or the program is not extended, the tuner 2 or the tuner 3 is required.
Is used as the main tuner. In the following description, the main tuner is described as the tuner 2 for convenience. However, the principle is the same even if the main tuner is the tuner 3.

A broadcast wave in which a signal called a program extension / temporary program control signal is superimposed on a normal program signal is received by the antenna 1 shown in FIG.
Is input to the tuner 3. In the tuner 2 which is the main tuner, a program is selected, and the received signal (video signal) is received.
Is transmitted to the image synthesizing display unit 6, and is displayed as a television screen on the display unit 8 as it is in a normal state. The tuner 2, which is the main tuner, constantly monitors the program extension / temporary program control signal. If the program extension / temporary program control signal is detected, the program extension / temporary program control signal determination unit 4
This control signal is sent to

The viewer inputs, for example, the following information to the viewing / recording condition setting unit 5 using a television screen (display unit 8) and a television remote controller. The viewing / recording condition setting unit 5 stores this information and sends it to the program extension / temporary program control signal determination unit 4. The information set by the viewer in advance is information indicating conditions such as a display method of a detour channel or the like at the time of program extension or a temporary program, its priority, and handling of a recorded output signal. Information to specify the area where the user lives, information to select whether or not to automatically switch channels for temporary programs other than the area where the user lives, information indicating the priority for the temporary program to the area where the user lives, and Information indicating the display format when the temporary program for the area where you live or the next program is displayed on the screen at the same time as the main program currently being viewed when the program is extended, and information specifying the channel selection for the recording output signal, etc. Can be included.

The program extension / temporary program control signal determination unit 4 determines the information set by the viewer, that is, the display method of the detour channel at the time of the program extension or the extraordinary program, the priority thereof, and the handling of the recording output signal. And the like, and the program extension / temporary program control signal received by the tuner 2, which is the main tuner, are compared and determined, and the result is sent to the image synthesizing display unit 6 and the recording signal selection unit 7, and the screen display And the selection control of the recording signal.

For example, based on a comparison result of comparing the priority in the program extension / temporary program control signal with the priority set in the viewing / recording condition setting unit 5, through the viewing / recording condition setting unit 5. The viewing conditions and recording conditions set in
The image is transmitted to the image synthesizing display unit 6 and the recording signal selecting unit 7 (to select one of the images of the tuner 2 and the tuner 3).

FIGS. 3A and 3B are screen configuration diagrams illustrating a method of displaying a composite screen. Based on the priority and display format set by the viewer via the viewing / recording condition setting unit 5, at the time of program extension or at the time of a temporary program, for example, FIG.
A two-screen display as shown in (a) and (b) is performed.

In FIG. 3A, the sub-screen is imposed in the main screen, and in FIG. 3B, the main screen and the sub-screen are displayed independently. However,
For example, when the priority set by the viewer is the lowest, that is, when the extension of the program or the handling of the temporary program is set to the lowest, the two-screen display as shown in FIGS. Instead, the character data superimposed on the program extension / temporary program control signal may be simply superimposed on the image composition display unit 6 and then displayed.

It is to be noted that, as shown in FIGS.
The video signal of the sub-screen in the screen display or the like can be obtained by controlling the tuner 3 which is the sub-tuner by the control signal from the program extension / temporary program control signal determination unit 4. At this time, for example, when switching from BS digital broadcasting to terrestrial broadcasting, the terrestrial channel number differs depending on the area. For example, in the Tokyo area,
HK General TV has one channel, but it has two channels in the Osaka area. Even in such a case, program extension and
The temporary program control signal determination unit 4 controls the tuner 2 or the tuner 3 using not only the channel number superimposed on the program extension / temporary program control signal but also the channel name (for example, “NHK total”). And

(Second Embodiment) FIG. 4 is a block diagram showing an overall configuration of a broadcast receiver according to a second embodiment. The configuration of the broadcast receiver 11 according to the second embodiment is different from the configuration of the broadcast receiver 10 according to the first embodiment of the present invention shown in FIG. In addition, the program extension / temporary program control signal determination unit 4 is replaced with the program extension / temporary program control signal determination unit 44.

Basically, the operation is the same as that of the broadcast receiver 10 according to the first embodiment shown in FIG. 1, but in this embodiment, only one tuner unit is provided as shown in FIG. 3 (that is, the tuner 2 alone), the two-screen display as shown in FIG. 3 is not performed. Therefore, program extension
The temporary program control signal determination unit 44 does not perform control for displaying two screens.

In the present embodiment, the character data superimposed on the program extension / temporary program control signal
To superimpose on the screen or automatically change the channel at the time of program extension / temporary program interruption based on the conditions set in advance by the viewer via the viewing / recording condition setting unit 5. ing.

[0040]

As described above, the broadcast receiver according to the present invention has the following excellent effects.
The broadcast receiver can change the display mode of the program according to the conditions set in advance by the viewer when the program is extended or when the temporary program is suddenly organized. In addition, since character data superimposed on the program extension / temporary program control signal can be displayed in a superimposed format, a signal to that effect is not output on the recording output, So-called "pretty recording" becomes possible.

According to the result of comparing and judging the separated control signal and the set output condition, the receiving channel is switched so that the program is not interrupted, and then the program is displayed / recorded based on the output format. For example, a receiver of a viewer living in the target area specified by the above conditions can view and record a temporary program or a new program on the original channel. In the receiver of the viewer who lives in the area, the display indicating that the temporary program is being performed appears on the screen, the channel is switched to the bypass channel, and the original program or the original extended program is continuously viewed without delay -Convenience can be improved according to the regional characteristics of the viewer, such as being able to record.
