Description

  The present invention relates to a broadcast receiving apparatus, a broadcast system, a broadcast receiving program, and a recording medium that receive push-type broadcast, reproduce content related to the broadcast, and present it to a user.

  As a form of a conventional information providing service, there are a pull type information service in which an information user actively pulls out information and a push type information service in which an information provider transmits information unilaterally.

  The most typical example of the former pull type information service is a website. The user acquires information by inputting a URL in the web browser or selecting a link displayed in the browser. On the other hand, in the push-type information service, the user does not need to perform operations such as inputting a URL or selecting a link, and the information transmitted by the service provider is automatically and passively received by the terminal, and the display or speaker is used. To output.

  Such a push-type information service has a usage method of transmitting information closely related to the region such as sale information and coupons to a terminal in a specific region such as a shopping street or a department store.

  For example, Patent Document 1 collects the location of a mobile device from location information that indicates a zone of a radio base station as a unit, and provides information closely related to a specific region only to a mobile device that exists in a desired region of the information provider A system is disclosed.

Similarly, as a method for providing information closely related to a specific area, so-called push-type broadcasting using a broadcast wave transmitted only to a specific area is known. In this method, in a terminal having a broadcast reception function, the user can acquire information by matching the reception channel to the frequency band of the broadcast wave.
Japanese Patent Publication “Japanese Patent Laid-Open No. 11-225375 (Publication Date: August 17, 1999)”

  In the system described in Patent Document 1, when the push type information service is provided by a communication network via a base station, the network traffic increases as the number of target mobile devices increases. As a result, there arises a problem that the use of other services such as voice calls and pull-type information services provided using the same network is hindered.

  On the other hand, in the push type broadcasting system, although the problem such as the above traffic increase does not occur, it is necessary for the user to know the existence of the broadcasting in advance or adjust the channel by operating the terminal. However, there is a problem that it cannot be used without noticing the presence of the service because it overlooks a signboard or street poster that informs the existence of the service, or it is not used because the channel operation is troublesome.

  The present invention has been made in view of the above problems, and a broadcast receiving device, a broadcast system, and a broadcast receiving device that improve user convenience when using push-type broadcasting (push-type information) through the broadcast receiving device. It is to provide a program and a recording medium.

In order to solve the above problems, a broadcast receiving apparatus according to the present invention provides
A signal demodulating means for generating multiplexed stream data by demodulating a signal of an arbitrary channel included in the broadcast wave;
Separation and decoding means for separating the stream data into individual data constituting broadcast content;
A broadcast receiving apparatus comprising output means for outputting the individual data,
Detecting means for detecting an activation control signal from the signal;
When the activation control signal is detected by the detection means, the signal demodulation means, the separation decoding means, and the activation control means for activating the output means are provided.

  According to the above configuration, the broadcast receiving apparatus generates multiplexed stream data by demodulating a signal of an arbitrary channel included in the broadcast wave. The stream data generated in this way is separated into individual data (text, image, audio, etc.) constituting the broadcast content and output. For example, images and moving images are output to a display, and sound is output to a speaker. Through these processes, the broadcast receiving apparatus reproduces the broadcast content.

  Here, the broadcast receiving apparatus detects an activation control signal from the signal. This activation control signal is a signal for controlling activation of each means included in the broadcast receiving apparatus. When the broadcast receiving apparatus detects the activation control signal, the broadcast receiving apparatus activates the signal demodulation means, the separation decoding means, and the output means. By this activation control, each means necessary for the reproduction of the broadcast content is in a state of being operated, so that the broadcast receiving apparatus can reproduce (output) the broadcast content and present it to the user.

  As described above, when the broadcast receiving apparatus detects the presence of a push-type broadcast, the broadcast reception apparatus automatically reproduces and presents the content of the push-type broadcast to the user. Therefore, there is an effect that the provider of the push-type broadcast service can reduce the time and effort of notifying the channel for performing the service in order for the user of the broadcast receiving apparatus to use the content of the push-type broadcast. In addition, there is an effect that the user of the broadcast receiving apparatus can reduce the trouble of manually setting the channel in order to use the push-type broadcast content. That is, there is an effect that it is possible to improve the convenience of the user when using the push type broadcast through the broadcast receiving apparatus.

A broadcast receiving apparatus comprising output means for outputting the individual data,
Detecting means for detecting a start control signal from the signal;
Vibration control means for vibrating the broadcast receiving device;
The apparatus further comprises activation control means for activating at least one of the output means and vibration control means when the activation control signal is detected by the detection means.

  According to the above configuration, the broadcast receiving apparatus generates multiplexed stream data by demodulating a signal of an arbitrary channel included in the broadcast wave. The stream data generated in this way is separated into individual data (text, image, audio, etc.) constituting the broadcast content and output. For example, images and moving images are output to a display, and sound is output to a speaker. Through these processes, the broadcast receiving apparatus reproduces the broadcast content.

  Here, the broadcast receiving apparatus detects an activation control signal from the signal. This activation control signal is a signal for controlling activation of each means included in the broadcast receiving apparatus. When the broadcast receiving apparatus detects the activation control signal, it activates at least one of the output means and the vibration control means.

  Thereby, when the output means is activated, predetermined information is output. For example, if the output means is a display means, a text or icon for notifying the presence of push-type broadcasting is displayed. On the other hand, if the output means is an audio output means, an electronic sound or music notifying the presence of push-type broadcast is output. Therefore, a user who sees these texts and icons or hears voice or music can know the presence of push-type broadcasting.

  On the other hand, when the vibration control unit is activated, the broadcast receiving apparatus vibrates with a vibration pattern that notifies the presence of push-type broadcast. A user who senses this vibration can know the presence of push-type broadcasting.

  As described above, when the broadcast receiving apparatus detects the presence of the push-type broadcast, the broadcast reception apparatus notifies the user of the presence of the push-type broadcast without reproducing the broadcast content. As a result, in situations where it is impossible for the user to view broadcast content, such as when driving a car, it is possible to reduce wasteful battery consumption and to make a mistake in driving operations due to the surprise that a broadcast receiving device has started suddenly. The effect that can avoid the situation of. As a result, it is possible to improve the convenience for the user when using push-type broadcasting through the broadcast receiving apparatus.

It further comprises switching control means for switching the channel of the signal extracted by the viewing tuner means to the other channel when the activation control signal is detected by the detection means.

  According to the above configuration, the broadcast receiving apparatus generates multiplexed stream data by demodulating a signal of an arbitrary channel included in the broadcast wave. The stream data generated in this way is separated into individual data (text, image, audio, etc.) constituting the broadcast content and output. For example, images and moving images are output to a display, and sound is output to a speaker. Through these processes, the broadcast receiving apparatus reproduces the broadcast content.

  Here, the broadcast receiving apparatus receives the broadcast wave through the tuner for detection, and extracts, from the broadcast wave, a signal of another channel different from the channel extracted by the tuner for viewing from the broadcast wave. Thereby, the activation control signal is detected from the signal of the other channel. This activation control signal is a signal for controlling activation of each means included in the broadcast receiving apparatus. When the broadcast receiving apparatus detects the activation control signal, the broadcast receiving apparatus switches the channel of the signal extracted by the viewing tuner means to the other channel.

  By this switching control, the broadcast receiving apparatus automatically receives and reproduces the broadcast content of the push-type broadcast channel whose presence is detected, and presents it to the user. Accordingly, there is an effect that the user can view the content of the push-type broadcast even while viewing other broadcast content. As a result, it is possible to improve the convenience for the user when using push-type broadcasting through the broadcast receiving apparatus.

In order to solve the above problems, a broadcast receiving apparatus according to the present invention provides

  According to the above configuration, the broadcast receiving apparatus generates multiplexed stream data by demodulating a signal of an arbitrary channel included in the broadcast wave. The stream data generated in this way is separated into individual data (text, image, audio, etc.) constituting the broadcast content and output. For example, images and moving images are output to a display, and sound is output to a speaker. Through these processes, the broadcast receiving apparatus reproduces the broadcast content.

  Here, the broadcast receiving apparatus receives the broadcast wave through the tuner for detection, and extracts, from the broadcast wave, a signal of another channel different from the channel extracted by the tuner for viewing from the broadcast wave. Thereby, the activation control signal is detected from the signal of the other channel. This activation control signal is a signal for controlling activation of each means included in the broadcast receiving apparatus. When the broadcast receiving apparatus detects the activation control signal, the broadcast receiving apparatus performs display for notifying the presence of the push-type broadcast, output of sound, and control of vibration to at least one of the output means and the vibration control means.

  A first embodiment according to the present invention will be described below with reference to the drawings.

Embodiment 1
(Configuration of push type broadcasting system 100)
FIG. 1 is a block diagram showing a schematic configuration of a push type broadcast system 100 (broadcast system) according to the present embodiment. As shown in FIG. 1, the push type broadcast system 100 includes a broadcast transmission device 101 and a broadcast reception device 201. In FIG. 1, the description is simplified by describing one broadcast transmitting apparatus 101 and one broadcast receiving apparatus 201. However, each of the broadcast transmitting apparatus 101 and the broadcast receiving apparatus 201 constituting the push type broadcast system 100 is not limited to one each. That is, the push type broadcast system 100 may include a plurality of either one or both of the broadcast reception device 201 and the broadcast transmission device 101.

(Configuration of Broadcast Transmission Device 101)
As shown in FIG. 1, a broadcast transmission apparatus 101 includes a multiplexing unit 102, a transmission path encoding unit 103, an activation control signal generation unit 104 (activation control signal generation means), a broadcast wave transmission unit 105, and a broadcast content storage unit 106. , And an antenna 107.

  The broadcast content accumulation unit 106 records (that is, accumulates) various data (text data, image data, audio data, and the like) constituting the broadcast content. The multiplexing unit 102 reads each piece of data necessary for configuring the broadcast content from the broadcast content storage unit 106, and generates one stream data obtained by multiplexing the data. For example, if the push-type broadcasting system 100 conforms to the current terrestrial digital television broadcasting standard ISDB-T, the multiplexing unit 102 conforms to the MPEG-2 standard by subdividing each read data. A TSP (Transport Stream Packet) is generated.

  The transmission path encoding unit 103 performs various processing (such as error correction encoding processing, carrier modulation processing, and frequency conversion processing) on the data multiplexed by the multiplexing unit 102, and thereby the frequency emitted as a broadcast wave. Convert to transmission signal. The various processes here correspond to OFDM (Orthogonal Frequency Division Multiplexing) modulation processing in an ISDB-T compliant system.

  The activation control signal generation unit 104 generates an activation control signal that is referred to during state control of the broadcast receiving device 201. The transmission path encoding unit 103 described above inserts the activation control signal generated by the activation control signal generation unit 104 into the transmission signal. Accordingly, the broadcast wave transmission unit 105 transmits a broadcast wave including the activation control signal to the outside of the broadcast transmission apparatus 101. The transmitted broadcast wave propagates in the atmosphere and is taken in as a signal into the broadcast receiving apparatus 201 through the antenna 208.

(Configuration of broadcast receiving apparatus 201)
Next, the configuration of the main part of the broadcast receiving apparatus 201 will be described. As shown in FIG. 1, a broadcast receiving apparatus 201 includes a tuner unit 202, a signal demodulation unit 203 (signal demodulation unit), an activation control signal detection unit 204 (detection unit, activation control unit), and a separation decoding unit 205 (separation decoding unit). ), A display unit 206 (output unit), an audio output unit 207 (output unit), and an antenna 208.

  The broadcast receiving apparatus 201 receives broadcast waves through the antenna 208. From the received broadcast wave, the tuner unit 202 extracts a signal of a channel that the user desires to view and outputs it to the signal demodulation unit 203. The signal demodulation unit 203 decodes the signal extracted by the tuner unit 202, and outputs the decoded stream data to the demultiplexing / decoding unit 205. The separation / decoding unit 205 decodes the input stream data into various data (data such as text, image, and sound) constituting the broadcast content, and outputs the data to the display unit 206 and the audio output unit 207.

  The display unit 206 reproduces an image, for example, by outputting image data from a display (not shown). On the other hand, the audio output unit 207 reproduces audio by outputting audio data to a speaker (not shown). That is, the broadcast receiving apparatus 201 reproduces broadcast content through these processes and presents it to the user.

  The activation control signal detection unit 204 detects the presence / absence of an activation control signal from the channel signal extracted by the tuner unit 202. When the activation control signal is detected, activation control is performed on the signal demodulating unit 203, the separation / decoding unit 205, the display unit 206, and the audio output unit 207. “Activation control” here means control for activating each member that has not yet been activated when a broadcast wave is received. By receiving this activation control, the signal demodulating unit 203, the separation / decoding unit 205, the display unit 206, and the audio output unit 207 execute each process to be executed by each member.

(Operation during push-type broadcasting)
Next, operations of the broadcast transmitting apparatus 101 and the broadcast receiving apparatus 201 when push-type broadcasting is performed in the push-type broadcasting system 100 will be described. When performing push-type broadcasting, the broadcast transmitting apparatus 101 inserts the activation control signal generated by the activation control signal generation unit 104 into the transmission signal by the transmission path encoding unit 103. Here, the activation control signal has a time characteristic shown in FIG. 2 as an example.

(Time characteristics of start control signal)
FIG. 2 is a diagram illustrating time characteristics of the activation control signal. In FIG. 2, the horizontal axis indicates time, and the vertical axis indicates the state (ON or OFF) of the activation control signal. The activation control signal is set from the OFF state to the ON state at the start of the push-type broadcast service, and continues to be ON during the service period. Also, when the broadcast ends, the state changes from the ON state to the OFF state, and the OFF state is continued until the service is resumed.

(Operation of broadcast receiving apparatus 201)
The operation when the broadcast receiving apparatus 201 receives a broadcast wave of push-type broadcasting will be described with reference to the flowchart of FIG. FIG. 3 illustrates a case where the broadcast receiving apparatus 201 performs activation control on the signal demodulating unit 203, the separation decoding unit 205, the display unit 206, and the audio output unit 207 when detecting the activation control signal from the received broadcast wave. It is a flowchart which shows the flow of a process of. As a precondition for the processing in FIG. 3, it is assumed that the broadcast receiving apparatus 201 is not receiving a specific channel.

  First, the broadcast receiving apparatus 201 initializes a channel index number n to 0 (S301). The channel index number n is not a so-called channel number corresponding to a frequency band assigned to each broadcasting station, but a number assigned in order from 0 to a channel that the tuner unit 202 can extract from a broadcast wave. The broadcast receiving apparatus 201 arbitrarily determines the allocation method.

  An example of assignment of the index number n is shown in FIG. FIG. 4 is a diagram illustrating an example of assignment of index number n. As shown in FIG. 4A, the broadcast receiving apparatus 201 may assign channel index numbers in the order of channel numbers that can be extracted by the tuner unit 202. Alternatively, as shown in FIG. 4B, channel numbers may be assigned to channel index numbers in the order of remote control IDs, and then channel numbers without remote control IDs may be assigned in an arbitrary order.

  After the initialization processing of the index number n, the tuner unit 202 extracts the channel n signal from the broadcast wave (S302). Next, the activation control signal detection unit 204 detects an activation control signal from the signal extracted by the tuner unit 202 (S303). Here, when the activation control signal detection unit 204 detects the activation control signal as an ON state, the activation control signal detection unit 204 activates the signal demodulation unit 203, the separation decoding unit 205, the display unit 206, and the audio output unit 207 (S306).

  On the other hand, when the activation control signal detection unit 204 detects the activation control signal as an OFF state, the activation control signal detection unit 204 performs channel switching control on the tuner unit 202 (S304). The switching control here is control for changing the channel number of the signal extracted by the tuner unit 202 from the current number to the next number. The process of FIG. 3 returns to S301 if n is equal to or greater than the total number of channels that can be extracted, and returns to S302 if not (S305).

(Function and effect)
As described above, in the broadcast receiving apparatus 201, the activation control signal detection unit 204 monitors all channels that can be received by the broadcast receiving apparatus 201. Then, when it is determined that push-type broadcasting has been started in any channel, activation control is performed on the signal demodulation unit 203, the separation decoding unit 205, the display unit 206, and the audio output unit 207. Thereby, the broadcast receiving apparatus 201 can reproduce the push-type broadcast content and present it to the user.

  That is, in the push type broadcast system 100 of the present embodiment, the broadcast receiving device 201 receives the broadcast content broadcast by the broadcast transmitting device 101. Then, when the activation control signal included in the broadcast content is ON, the broadcast receiving apparatus 201 automatically reproduces the broadcast content without the user's operation and presents it to the user. Therefore, the provider of the push-type broadcast service can reduce the time and effort of notifying the channel for performing the service in order for the user of the broadcast receiving apparatus 201 to use the content of the push-type broadcast. In addition, the user of the broadcast receiving apparatus 201 can save time and labor for manually setting a channel in order to use push-type broadcast content. That is, it is possible to improve user convenience when using push-type broadcasting through the broadcast receiving apparatus 201.

  In the present embodiment, all data constituting the broadcast content is presented to the user. However, if the broadcast receiving apparatus 201 is, for example, a flip type (that is, foldable) apparatus, the user cannot view an image reproduced by the display unit 206 in the flip closed state. Therefore, in the flip closed state, the activation control signal detection unit 204 activates the audio output unit 207 without activating the display unit 206 so that only the audio is output without displaying an image. Good.

(Other first configuration of broadcast transmitting apparatus)
In the example of FIG. 1, the content that the broadcast transmitting apparatus 101 broadcasts to the broadcast receiving apparatus 201 is stored in advance in the broadcast content storage unit 106. However, the broadcast content may be outside the broadcast transmission apparatus 101.

  A broadcast transmitting apparatus 1701 having such a configuration will be described below with reference to FIG. FIG. 17 is a block diagram showing another main configuration of the broadcast transmitting apparatus according to the first embodiment of the present invention. As shown in this figure, a broadcast transmission apparatus 1701 includes a multiplexing unit 1702, a transmission path encoding unit 1703, an activation control signal generation unit 1704 (activation control signal generation means), a broadcast wave transmission unit 1705, and an audio encoding unit 1706. , An image encoding unit 1707 and an antenna 1708. The broadcast transmission device 1701 is connected to a camera 1708 and a microphone 1709, respectively.

  Multiplexer 1702, transmission path encoder 1703, activation control signal generator 1704, broadcast wave transmitter 1705, and antenna 1708 included in broadcast transmitter 1701 are multiplexed by transmission unit 102 and transmission included in broadcast transmitter 101, respectively. It is the same as the path encoding unit 103, the activation control signal generation unit 104, the broadcast wave transmission unit 105, and the antenna 107.

  In the broadcast transmitting apparatus 1701, the image encoding unit 1707 encodes an image input from the camera 1708 in real time. On the other hand, the voice encoding unit 1706 encodes the voice input from the microphone 1709 in real time. Thereby, the broadcast content is multiplexed and transmitted to the broadcast receiving apparatus 201.

(Other second configuration of broadcast transmitting apparatus)
A broadcast transmission apparatus 1801 having another configuration for acquiring contents from the outside and broadcasting will be described below with reference to FIG. FIG. 18 is a block diagram showing another main configuration of the broadcast transmitting apparatus according to the first embodiment of the present invention. As shown in this figure, a broadcast transmission apparatus 1801 includes a multiplexing unit 1802, a transmission path encoding unit 1803, an activation control signal generation unit 1804 (activation control signal generation means), a broadcast wave transmission unit 1805, a network connection unit 1807, And an antenna 1808. The broadcast transmission apparatus 1801 is connected to the content server 1808 via the network 1809. The network 1809 is, for example, the Internet. The content server 1808 stores (that is, stores) the broadcast content described above.

  Multiplexer 1802, transmission path encoder 1803, activation control signal generator 1804, broadcast wave transmitter 1805, and antenna 1808 included in broadcast transmission apparatus 1801 are multiplexed by transmission section 102 and transmission included in broadcast transmission apparatus 101, respectively. It is the same as the path encoding unit 103, the activation control signal generation unit 104, the broadcast wave transmission unit 105, and the antenna 107.

  In the example of FIG. 18, the network connection unit 1807 accesses the content server 1808 via the network 1809 to acquire the broadcast content stored in the content server 1808 and output it to the multiplexing unit 1802. Therefore, the broadcast transmitting apparatus 1801 can multiplex external broadcast content and transmit it to the broadcast receiving apparatus 201.

  Note that the above-described broadcast transmitting apparatuses 101, 1701, and 1801 all assume that one broadcast content is broadcast to the broadcast receiving apparatus 201. Here, these devices may retransmit broadcasts to areas where broadcast waves are difficult to reach, such as underground malls and indoors. When re-transmission is performed, the broadcast target area is limited, which is suitable for transmitting information closely related to the area, which is one form of push-type broadcast. Accordingly, FIGS. 15 and 16 show a broadcast transmitting apparatus having a configuration suitable for transmitting information closely related to a region.

(First example)
FIG. 15 is a block diagram illustrating a main configuration of a broadcast transmitting apparatus 1501 that transmits push-type broadcast content closely associated with an area when performing re-transmission. As shown in this figure, a broadcast transmitting apparatus 1501 includes a remultiplexing unit 1502, a transmission path encoding unit 1503, an activation control signal generation unit 1504 (activation control signal generation means), a broadcast wave transmission unit 1505, a broadcast content storage unit. 1506, a main broadcast receiving unit 1507, an antenna 1508, and an antenna 1509.

  The transmission path encoding unit 1503, the activation control signal generation unit 1504, the broadcast wave transmission unit 1505, the broadcast content storage unit 1506, and the antenna 1508 included in the broadcast transmission apparatus 1501 are each a transmission path encoding unit included in the broadcast transmission apparatus 101. 103, the activation control signal generation unit 104, the broadcast wave transmission unit 105, the broadcast content storage unit 106, and the antenna 107.

  In the broadcast transmitting apparatus 1501, the main broadcast receiving unit 1507 receives the broadcast wave transmitted from the main broadcast station 1508 through the antenna 1508 and outputs the broadcast wave to the remultiplexing unit 1502. The broadcast content storage unit 1506 stores content data for push-type broadcasting. Therefore, the remultiplexing unit 1502 reads the content data from the content storage unit 1506 and multiplexes it with the input broadcast wave. As a result, the broadcast transmission apparatus 1501 retransmits the broadcast wave in which the content data is multiplexed toward an area where the broadcast wave from the main broadcast station 1508 is difficult to reach directly.

(Second example)
FIG. 16 is a diagram illustrating a configuration of a main part of a broadcast transmission device 1601 that transmits broadcast content of a push-type broadcast that is in close contact with a region when performing re-transmission. The broadcast transmission device 1601 multiplexes the broadcast content received from the IP broadcast station 1608 connected to the network 1609 with the content data for push-type broadcast stored in the broadcast content storage unit 1606 and retransmits it. As shown in this figure, a broadcast transmitting apparatus 1601 includes a remultiplexing unit 1602, a transmission path encoding unit 1603, an activation control signal generation unit 1604 (activation control signal generation means), a broadcast wave transmission unit 1605, a broadcast content storage unit. 1606, a network connection unit 1607, and an antenna 1608. The broadcast transmission device 1601 is connected to the IP broadcast station 1609 via the network 1610. The network 1609 is, for example, the Internet.

  The transmission line encoding unit 1603, the activation control signal generation unit 1604, the broadcast wave transmission unit 1605, the broadcast content storage unit 1606, and the antenna 1608 included in the broadcast transmission device 1601 are each a transmission line encoding unit included in the broadcast transmission device 101. 103, the activation control signal generation unit 104, the broadcast wave transmission unit 105, the broadcast content storage unit 106, and the antenna 107.

  In the example of FIG. 16, the IP broadcast station 1609 transmits a broadcast wave to the broadcast transmission device 1601 via the network 1610. This broadcast wave is received by the network connection unit 1607 in the broadcast receiving apparatus 201 and output to the remultiplexing unit 1602. The broadcast content storage unit 1606 stores content data for push-type broadcasting. Therefore, the remultiplexing unit 1602 reads the content data from the content storage unit 1606 and multiplexes it with the broadcast wave input from the network connection unit 1607. As a result, the broadcast transmission device 1601 retransmits the broadcast wave in which the content data is multiplexed toward an area where the broadcast wave from the main broadcasting station 1608 is difficult to reach directly.

  In general, it is known that a device that receives push-type broadcasts may hinder user convenience. As an example, in a place where quietness is required such as in a library, a push-type broadcast sound may be output against the user's intention. As another example, in a situation where the user cannot view the broadcast content (such as driving a car), the broadcast content is automatically played back, resulting in wasteful power consumption.

  Therefore, in the second embodiment of the present invention described below, in view of such a problem, it is possible to notify the user of the presence of push-type broadcasting without outputting broadcast content.

That is, in the broadcast receiving apparatus 501, the activation control signal detection unit 504 controls activation of at least one of the display unit 506, the audio output unit 507, and the vibration control unit 509 when detecting the activation control signal. Here, “activation control” refers to activation of at least one of the display unit 506, the audio output unit 507, and the vibration control unit 509 that have not been activated before detection of the activation control signal after detection of the activation control signal. It means to make it a state to be made.

(Display the presence of push-type broadcasting on the screen)
When the display unit 506 receives the activation control from the activation control signal detection unit 504, the display unit 506 displays, for example, text as illustrated in FIG. 8 after activation. FIG. 8 is a diagram illustrating an example of a text display when a push-type broadcast is detected. This text includes contents for notifying the user of the presence of push-type broadcasting. Therefore, the user who has read the text in FIG. 8 can know that push-type broadcasting exists and can be received through the broadcast receiving apparatus 501.

  Further, when the display unit 506 receives the activation control from the activation control signal detection unit 504, the display unit 506 displays an icon 901 as illustrated in FIG. 9 after the activation, for example. FIG. 9 is a diagram illustrating an example of icon display when a push-type broadcast is detected. The icon 901 includes contents for notifying the user of the presence of push-type broadcasting. Therefore, the user who sees the icon in FIG. 9 can know that push-type broadcasting exists and can be received through the broadcast receiving apparatus 501.

  Note that the text in FIG. 8 and the icon 901 in FIG. 9 are merely examples. The display unit 506 may display text of other words or icons (images) of other designs as long as the content can notify the user of the presence of the push-type broadcast.

(Notification of the existence of push-type broadcasting by voice)
When the audio output unit 507 receives the activation control from the activation control signal detection unit 504, the audio output unit 507 outputs a predetermined audio (electronic sound, music, etc.) that informs the user of the presence of the push-type broadcast after the activation. By listening to such sound, the user can know the presence of push-type broadcasting.

(Notice by vibration)
When receiving the activation control from the activation control signal detection unit 504, the vibration control unit 509 causes the broadcast receiving device 501 to vibrate after activation. Such vibration allows the user to know the presence of push-type broadcasting.

  Whether the activation control signal detection unit 504 controls activation of any one of the display unit 506, the audio output unit 507, and the vibration control unit 509, or a combination of these activations, controls whether or not the broadcast receiving device 501. It may be determined in advance. The user may set as appropriate. The broadcast receiving terminal 501 may not be provided if the vibration control unit 509 is not used.

Thereby, the convenience of the user at the time of using the broadcast receiving apparatus 501 can be improved. For example, it is possible to prevent a voice that is contrary to the user's intention from being output when quietness is required. Or, since the content is not reproduced in a situation where the user cannot view, it is possible to prevent wasteful consumption of power.

[Embodiment 3]
A third embodiment according to the present invention will be described below with reference to the drawings.

(Configuration of broadcast receiving apparatus 601)
First, a main configuration of the broadcast receiving apparatus 601 according to the present embodiment will be described below with reference to FIG. FIG. 6 is a block diagram showing a main configuration of a broadcast receiving apparatus 601 according to the third embodiment of the present invention. As shown in this figure, a broadcast receiving apparatus 601 includes a detection tuner unit 602 (detection tuner unit), a signal demodulation unit 603 (signal demodulation unit), an activation control signal detection unit 604 (detection unit, switching control unit), A separation / decoding unit 605 (separation decoding unit), a display unit 606 (output unit), an audio output unit 607 (output unit), an antenna 608, and a viewing tuner unit 610 (viewing tuner unit) are provided.

  A signal demodulation unit 603, a separation / decoding unit 605, a display unit 606, and an audio output unit 607 included in the broadcast reception device 601 are respectively a signal demodulation unit 203, a separation / decoding unit 205, a display unit 206, and This is the same as the audio output unit 207. Each of the detection tuner unit 602 and the viewing tuner unit 610 receives a broadcast wave, and extracts a signal of a designated channel from the received broadcast wave. In the broadcast receiving device 601, it is the viewing tuner unit 610 that extracts the broadcast content signal that the user actually views.

  In the broadcast receiving apparatus 601 of the present embodiment, as shown in FIG. 6, the object and content of control by the activation control signal detection unit 604 are different from those of the activation control signal detection unit 204. Specifically, the activation control signal detection unit 604 performs channel switching control on the viewing tuner unit 610 when detecting the activation control signal. Here, “channel switching control” means control for switching the channel number of the signal extracted from the broadcast wave by the viewing tuner unit 610 to the channel number of push-type broadcasting. With this control, the broadcast receiving apparatus 601 forcibly switches the channel being viewed to a push-type broadcast channel.

(Operation during push-type broadcasting)
The operation of the broadcast receiving device 601 when receiving the push-type broadcast will be described below with reference to FIG. FIG. 10 is a flowchart showing the flow of processing when the broadcast receiving apparatus 601 according to the third embodiment of the present invention forcibly switches the reception channel to that of the push type broadcast when detecting the activation control signal. It is.

  As shown in this figure, the broadcast receiving apparatus 601 first initializes the channel index number n to 0 (S1001). The channel index number n is not a so-called channel number corresponding to a frequency band assigned to each broadcasting station, but a number assigned in order from 0 to a channel that can be extracted from the broadcast wave by the detection tuner unit 602. is there. The broadcast receiving apparatus 601 arbitrarily determines the allocation method.

  After the initialization of the channel index number n is completed, the detection tuner unit 602 extracts the signal of the index number n from the received broadcast wave (S1002). Then, the activation control signal detection unit 604 detects an activation control signal from the extracted signal (S1003). When the activation control signal detection unit 604 detects the activation control signal as an ON state, the activation control signal detection unit 604 controls the viewing tuner unit 610 to switch to the corresponding channel (S1006).

  After performing the switching control to the corresponding channel, the activation control signal detection unit 604 performs channel switching control on the detection tuner unit 602 in order to extract the activation control signal of the next channel (S1004). Here, “channel switching control” controls the detection tuner unit 602 to extract a signal with the new index number n by adding one value to the current index number n. That is. Even when the activation control signal detection unit 604 detects the activation control signal as an OFF state, the activation control signal detection unit 604 performs channel switching control on the detection tuner unit 602 in order to extract the activation control signal of the next channel (S1004). .

  After completing the process of S1004, the activation control signal detection unit 604 determines whether the index number n is equal to or greater than the total number of channels that can be extracted (S1005). When the result of this determination is “true” (YES), the processing returns to S1001, and when it is “false” (NO), the processing returns to S1002 (S1005).

(Function and effect)
As described above, the broadcast receiving apparatus 601 according to the present embodiment monitors the signal states of all channels that can be received as broadcast waves. When it is detected that push-type broadcasting has started in any channel (that is, the activation control signal is detected from the received signal), the channel of the broadcast wave received by the viewing tuner unit 610 is detected. Switch to the selected channel. Accordingly, the broadcast receiving apparatus 601 can automatically reproduce the detected push-type broadcast content without accepting an operation by the user and present it to the user. Therefore, the convenience of the user when using the broadcast receiving apparatus 601 is improved.

[Embodiment 4]

  A signal demodulation unit 703, a separation / decoding unit 705, a display unit 706, an audio output unit 707, a vibration control unit 709, and an antenna 708 provided in the broadcast receiving device 701 are respectively a tuner unit 502 and a signal demodulation unit provided in the broadcast receiving device 501. 503, the separation / decoding unit 505, the display unit 506, the audio output unit 507, the antenna 508, and the vibration control unit 509. In addition, the detection tuner unit 702 and the viewing tuner unit 710 included in the broadcast receiving device 701 are the same as the detection tuner unit 602 and the viewing tuner unit 610 included in the broadcast receiving device 601, respectively.

  Here, as shown in FIG. 7, in the broadcast receiving device 701, when the activation control signal detection unit 704 detects the activation control signal, at least one of the display unit 706, the audio output unit 707, and the vibration control unit 709. On the other hand, output control is performed to notify the user of the presence of push-type broadcasting. Here, “output control” refers to push-type broadcasting after detecting the activation control signal in at least one of the display unit 706, the audio output unit 707, and the vibration control unit 709 that have already been activated for viewing the broadcast. This means that text and icons for notifying the existence of the voice, icon display, voice output, vibration pattern output, etc. are performed.

  The contents output to the display unit 706, the audio output unit 707, and the vibration control unit 709 by the output control by the activation control signal detection unit 704 are the ones by the activation control signal detection unit 504 according to the second embodiment of the present invention. Are the same. That is, when output control is performed by the activation control signal detection unit 704, the display unit 706 displays text and icons that notify the presence of push-type broadcasting. On the other hand, the audio output unit 707 outputs audio notifying the presence of push-type broadcasting. Also, the vibration control unit 709 vibrates the broadcast receiving device 701 with a vibration pattern that notifies the presence of push-type broadcasting. With these controls, the broadcast receiving apparatus 701 can notify the user of the presence of push-type broadcasting even while the user is viewing other programs.

(Operation of broadcast receiving apparatus 701)
The operation of the broadcast receiving apparatus 701 when receiving the push-type broadcast is shown in the flowchart of FIG. FIG. 11 illustrates activation of at least one of the display unit 706, the audio output unit 707, and the vibration control unit 709 when the broadcast receiving device 701 according to the fourth embodiment of the present invention detects the activation control signal. It is a flowchart which shows the flow of the process at the time of controlling.

  The operation when the broadcast receiving device 701 receives a push-type broadcast is basically the same as that of the broadcast receiving device 601. However, the broadcast receiving apparatus 601 performs channel switching control in S1006, whereas the broadcast receiving apparatus 701 performs at least one of the display unit 706, the audio output unit 707, and the vibration control unit 709 in S1106 corresponding to S1006. Perform output control.

  The target member for which the activation control signal detection unit 704 performs activation control may be any one of the display unit 706, the audio output unit 707, and the vibration control unit 709. Or some combination of these may be sufficient. The combination may be set in advance in the broadcast receiving apparatus 701 or may be set by the user.

  Whether the activation control signal detection unit 704 controls the output to any one of the display unit 706, the audio output unit 707, and the vibration control unit 709, or whether to control a plurality of combinations of these outputs is broadcast reception. What is necessary is just to be predetermined in the apparatus 701. The user may set as appropriate. The broadcast receiving device 701 may not be provided if the vibration control unit 709 is not used.

  When a plurality of different push-type broadcasts are detected (that is, when a plurality of different start-up control signals are detected), activation control signal detection unit 704 performs output control according to the number of detected push-type broadcasts. You may go. In this case, the display unit 706 displays text and icons indicating the number of detected push-type broadcasts. Also, the audio output unit 707 outputs audio indicating the number of detected push type broadcasts. In addition, the vibration control unit 709 vibrates the broadcast receiving device 701 with a vibration pattern indicating the number of detected push-type broadcasts.

  In any case, the broadcast receiving apparatus 701 can notify the user of the number of push-type broadcasts. The display unit 706 may display a list of names of a plurality of push type broadcasts, for example. In this case, the user can select and view a desired push type broadcast from a plurality of push type broadcasts.

(Function and effect)
As described above, the broadcast receiving apparatus 701 according to the present embodiment can notify the user of the presence of the push-type broadcast even when the user is viewing another program. Thereby, the convenience of the user at the time of using the broadcast receiving apparatus 701 can be improved. For example, it is possible to know the presence of push-type broadcasting without missing a highlight scene of a program being viewed, and to switch to push-type broadcasting at a user's desired timing, for example, after the highlight scene ends. When there are a plurality of push-type broadcasts, the user can select and view a desired push-type broadcast.

(Additional notes)
In any of the first to fourth embodiments described above, the push-type broadcast service detection process by the tuner unit and the activation control signal detection unit may be performed intermittently. In the case of a broadcast receiving apparatus that is assumed to be carried by the user, it is desirable that the battery serving as the power supply source has as long a duration as possible. Therefore, when the broadcast receiving apparatus intermittently performs the push type broadcast service detection process, it is possible to reduce power consumption per hour and battery consumption.

(Characteristics of start control signal)
As an example of the activation control signal generated by the activation control signal generation unit 104 described above, a signal that maintains the ON state during the push broadcast service period as shown in FIG. Similarly, there is an ISDB-T emergency warning broadcast activation flag that indicates a broadcast period by an ON or OFF signal. This flag is included in a TMCC (Transmission and Multiplexing Configuration Control) signal. The broadcast receiving apparatus monitors this flag, and when the flag is turned ON and the area_code described in the emergency information descriptor of the PMT (Program Map Table) matches the area code set in the broadcast receiving apparatus, Select and receive the service described in the information descriptor.

  The broadcast receiving apparatus monitors the emergency warning broadcast activation flag in order to respond to the emergency warning broadcast. From the viewpoint of circuit scale and power saving, it is desirable that the push-type broadcast service can be detected by monitoring the TMCC signal. Therefore, a flag indicating the presence or absence of the push type broadcast service is added to the TMCC signal. Alternatively, the emergency warning broadcast activation flag is shared as the push type broadcast service activation flag. When sharing, it is important to identify the emergency warning broadcast. In the case of sharing, the emergency information descriptor start_end_flag is set to 0 (test mode) to prevent malfunction.

  For example, ON / OFF of the emergency warning broadcast activation flag may be switched periodically. An example of this is shown in FIG. FIG. 12 is a diagram illustrating an example of a signal that can be distinguished from the emergency warning broadcast when the emergency warning broadcast activation flag of the TMCC signal is used as the activation control signal. The emergency warning broadcast and the push-type broadcast can be distinguished by the switching pattern shown in FIG. That is, in emergency alert broadcasting, the period from when the emergency alert broadcast activation flag is set to 0 to 1 is determined to be 1 second or longer and 4 OFDM frames or longer. Therefore, it is preferable to conform to this in order to prevent malfunction. .

  Further, an emergency information descriptor may be used. FIG. 13 is a diagram illustrating the syntax of the emergency information descriptor defined in ARIB STD-B10. There are six “reserved_future_use” as reserved areas. Therefore, one of these may be added to the reserve area of the emergency information descriptor as a flag indicating push-type broadcasting. An example of this is shown in FIG. FIG. 14 is a diagram illustrating a syntax example of an emergency information descriptor that enables discrimination from an emergency alert broadcast when an emergency alert broadcast activation flag of a TMCC signal is used as an activation control signal.

  In the example of this figure, “push-base_broadcast_flag” is added to the reserve area of the emergency information descriptor as a flag indicating push-type broadcasting. The activation control signal detector can confirm the emergency warning broadcast and the push type broadcast by confirming this flag.

  Moreover, you may provide the descriptor which shows push type | mold broadcast in PMT.

In the broadcast receiving apparatus according to the present invention,
The output means is a display means,
Preferably, the activation control means activates the display means to display information notifying the presence of push-type broadcasting.

  According to said structure, there exists an effect which can notify a user reliably of presence of push type | mold broadcast.

In the broadcast receiving apparatus according to the present invention,
The output means is an audio output means,
Preferably, the activation control means activates the display means to output a sound notifying the presence of push-type broadcasting.

  According to said structure, there exists an effect which can notify a user reliably of presence of push type | mold broadcast.

  In the broadcast receiving apparatus according to the present invention, it is further preferable that the activation control signal periodically repeats an ON state and an OFFF state.

  According to the above configuration, when the emergency alarm start flag of the TMCC (Transmission and Multiplexing Configuration Control) signal is used as the start control signal, it is possible to distinguish between the push-type broadcast and the emergency alert broadcast and prevent malfunction of the apparatus. .

In this case, the program code is supplied to the broadcast receiving apparatus via the communication network. The communication network is not limited to a specific type or form as long as it can supply the program code to the broadcast receiving apparatus. For example, it may be the Internet, intranet, extranet, LAN, ISDN, VAN, CATV communication network, virtual private network, telephone line network, mobile communication network, satellite communication network, and the like.

  The transmission medium constituting the communication network may be any medium that can transmit the program code, and is not limited to a specific configuration or type. For example, wired communication such as IEEE 1394, USB (Universal Serial Bus), power line carrier, cable TV line, telephone line, ADSL (Asymmetric Digital Subscriber Line) line, infrared rays such as IrDA and remote control, Bluetooth (registered trademark), 802.11 It can also be used by radio such as radio, HDR, mobile phone network, satellite line, terrestrial digital network. The present invention can also be realized in the form of a computer data signal embedded in a carrier wave in which the program code is embodied by electronic transmission.
