Abstract

PROBLEM TO BE SOLVED: To dynamically change the broadcasting (reproduction) a propriety of broadcast contents corresponding to the conditions of a reception side or the needs of a viewer. SOLUTION: In this broadcasting/reception system, a broadcast contents program 51 transmitted from a broadcasting station 10 is received by this receiver 20. The received broadcast contents program 51 is divided into three, the value of the broadcast contents 511 is stored in a broadcast contents storage 202, the value of contents attributes 512 is stored in a contents attribute storage 203 and the value of an execution program 513 is stored in an execution program storage 204. Then, an execution program engine 205 interprets and executes the program in the execution program storage 204 and judges whether to deliver the broadcast contents 511 in the broadcast contents storage 202 to a reproduction part 206 or to abandon the broadcast contents 511 by referring to the value of the contents attributes 512 and the value of attributes stored in a user attribute storage part 207.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for selecting information by digital broadcasting, and more particularly, to whether or not broadcast of transmitted broadcast content can be performed according to the time situation, spatial situation, taste situation, etc. of a receiving viewer. The present invention relates to a broadcast receiving system, a broadcasting device, and a receiving device that can be changed appropriately or appropriately.

[0002]

2. Description of the Related Art Digital broadcasting is becoming popular in Japan and the United States. In digital broadcasting, not only broadcasting contents but also data broadcasting for broadcasting data that can be processed by a computer is possible.

[0003] When data broadcasting becomes possible, attribute information of broadcast contents is attached, and it is possible to filter on the receiver side by judging from the attribute information whether or not the program is a viewer's favorite program. Various methods have been proposed at present (for example, see "Digital Broadcasting" Nishimasa, Atsuko Nomura (Chuo Keizai Publishing) or "Future Map of the ITS Business" Dentsu Research Institute (Sankaido Publishing)).

[0004]

A conventionally proposed selective broadcast function of broadcast content is to add attribute data to the broadcast content. Also, the algorithm of the filter on the receiver side was fixed. Therefore, there is a merit that the addition of the attribute information to the broadcast content is relatively easy, but there is a problem that it is impossible even if it is desired to introduce a different selection criterion for each broadcast content.

However, as proposed in the present invention, CM
Considering the future development of broadcast contents such as (Commercial Message), it is effective to broadcast CMs according to the preferences and necessity of each individual (customer) instead of broadcasting the same CM to the general public. It is a power of differentiation. In order to realize this, it is necessary to determine whether or not the broadcast content can be broadcast based on different criteria for each broadcast content. In addition, the determination as to whether or not to broadcast based on such different criteria dynamically changes according to the situation on the receiving side.

For example, if a commercial for a product for snow damage countermeasures is to be played, it does not make much sense to broadcast it to a southern country, and it is better to be able to selectively receive only a receiver in a snowy country. Furthermore, the CM does not broadcast on sunny days,
Broadcasting on a heavy snow day is more efficient. If the receiver has a mechanism to obtain the weather information of the place on that day, it can be broadcast only on a heavy snowy day by combining it.

[0007] Alternatively, in a country with strong local autonomy, the contents that can be advertised may differ from state to state. For example, states that do not advertise alcohol, states that do not advertise guns, and so on. In such a case, sake advertisements cannot be given to states where alcohol advertisements are not allowed, so it is necessary to determine whether or not to broadcast by segmenting each region.

It is one method to prepare a different channel for each state, but it is inconvenient in the border area of the state because both radio waves reach. Therefore, GPS receiver
(Global Positioning System
m), the receiver may determine to which state the receiver belongs to based on the accurate location information of the receiver and thereby determine whether broadcasting is possible by the receiver. Is resolved.

Conventional broadcast contents have been broadcast to all recipients indiscriminately if channels are tuned. However, if adaptation of broadcast contents to individual viewers evolves, whether broadcast is possible or not for each broadcast content is considered. The criterion differs for each receiver.

[0010] This difference is due to the WWW (WORL) of the Internet.
D WIDE WEB). Initially (19
WWW (until around 1994) was implemented using a static HTML language and a WWW browser that executes it. Static H
TML (HyperTextMarkup Langu)
An age language is like a word processor file. When you download a static HTML language with a WWW browser, an image like a word processor appears on the screen. Unlike a word processor, it cannot be edited. Therefore, when a certain WWW content is released, the URL
(Uniform Resource Locate
If you type r), the same HTML will be used for any WWW browser.
Content was only displayed.

After that, script languages such as JAVA (registered trademark) applet, JAVA SCRIPT and VBSCRIPT appeared, but these are programs executed on the WWW browser side. The creator of the HTML content bundles the HTML content with a program such as a JAVA applet or a script language, and transmits the program. On the WWW browser side, the bundled program is executed, and each user of the WWW browser has a completely different program. Now you can do different things.

[0012] As a similar idea, there is a concept of an active network in the field of a network protocol (Reference: "Active network: using a network for customization", by Obana and Sugiyama, Information Processing, 1999/6, Vol. 40, No. 6, Information Processing Society of Japan).

Although the network protocol in the field of the Internet is TCP / IP, realizing all packets with the same protocol may be useless.
Therefore, the packet must have the protocol required for the minimum network conversation as a common language, but for the additional part, a program that interprets the protocol of the additional part is bundled and sent out. Run the bundled program to interpret the additional protocol.

A first object of the present invention is to realize the concept of JAVA applets and script languages used in WWW contents in digital broadcast contents and flexibly respond to the needs of viewers. It is an object of the present invention to provide a specific programmable selective broadcast receiving system, a broadcasting device, a receiving device, and a method thereof.

[0015] A second object of the present invention is that a broadcaster can specify the situation in which a receiver wants a receiver to view the broadcast content together with the broadcast content transmitted by the broadcaster. It is an object of the present invention to provide a programmable selective broadcast receiving system, a broadcasting device, and a receiving device capable of dynamically changing whether broadcast is possible or not according to a situation on the receiving side.

Further, a third object of the present invention is to provide an ID (Identificatio) of an execution program to be executed.
It is an object of the present invention to provide a programmable selective broadcasting system, a broadcasting apparatus, a broadcasting receiving apparatus, and a method thereof, which can save broadcast capacity and realize easiness of management by attaching only n Data) to broadcast content.

Further, a fourth object of the present invention is to provide a program-selective program which can easily realize loading of the execution program on the receiver side by collectively downloading the execution program to the reception side using broadcasting. A broadcast receiving system, a broadcasting device, and a receiving device are provided.

[0018]

According to a first aspect of the present invention, there is provided a programmable selective broadcast receiving system or the like, which includes broadcast contents and an execution program for the broadcast contents, and interprets and executes the execution program on the receiver side. It is characterized in that it is determined whether or not to broadcast (reproduce) the enclosed broadcast content according to the user's time situation, space situation, taste situation, and the like. Further, the present invention is characterized in that it is determined whether or not to broadcast (reproduce) broadcast contents transmitted at once according to the situation on the viewer side.

In the programmable selective broadcast receiving system according to the second aspect of the present invention, a typical execution program is prepared as a kind of cache on the receiver side, and the broadcasting station sends out the execution program itself as a broadcast content program. Instead, only the ID of the execution program to be executed is attached to the broadcast content. The receiver side is characterized in that it refers to the ID and selects and executes an execution program to be executed.

Further, in a third aspect of the present invention, in the caching of the execution program used in the second invention, the execution program is periodically transmitted from a broadcasting station to execute the execution program. And a mechanism for caching.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a broadcast receiving system according to the present invention comprises a broadcast station 10 and a receiving apparatus 2 such as a receiving apparatus mounted on an automobile or a mobile terminal apparatus.
0, a digital broadcasting satellite 30, and a GPS satellite 40. In FIG. 1, the broadcast station 10 creates a broadcast content program 50 and transmits it to the receiving device 20 via the digital broadcast satellite 30.

The broadcast content program 50 includes broadcast content, content attributes, and an execution program. For example, in the case of a CM, the broadcast content is the CM content itself. Further, when a commercial of a product for snow damage countermeasures is to be played, information that can be selectively received only by a receiving device in a snowy country (for example, area A of areas A to C), alcohol, gun, etc. For states where commercials are not allowed, such information is used to determine whether broadcasting is possible or not by segmenting each state.

The execution program is an interpretation program bundled with data called broadcast contents. As described above, in the present invention, the JAVA applet (HTML
Unlike an active network (included in a network protocol) and an active network (included in a network protocol), an interpretation program is included for data called broadcast content.

The receiving device 20 has a GPS (not shown), receives position information from a GPS satellite 40, and determines which state (areas A to C) the receiving device belongs to. The program is compared with the attribute (for example, position information) of the broadcast content transmitted from the broadcast station 10, and the execution program determines whether or not the broadcast is possible. When broadcasting is permitted, the broadcast content is played back, and images and sound are displayed.
In the case of no broadcast, the broadcast content is not played back,
No audio display. The receiving device may be a TV receiver that can receive and process the broadcast content program 50.

Embodiments 1 to 3 show more specific examples of the broadcasting system, apparatus and method of the present invention. (Embodiment 1) FIG. 2 showing a first embodiment of the present invention.
, The broadcast station 10 includes a broadcast content program creation unit 101 and a transmission unit 102. The receiving device 20 includes a receiving unit 201 and a broadcast content storage unit 20.
2, a content attribute storage unit 203, an execution program storage unit 204, a program engine unit 205, a reproduction unit 206, a user attribute storage unit 207, a current time acquisition unit 208, a current location acquisition unit 209, Attribute input unit 21
0 is included.

Hereinafter, the operation of this embodiment will be described.
In the broadcast content program creation unit 101 of the broadcast station 10, for example, as shown in FIG.
11, digital data of the broadcast content program 51 including the content attribute 512 and the execution program 513 is created. The broadcast content 511 is the broadcast content itself (for example, “A man drinking at midnight is ...”), and the content attribute 512 is the attribute (for example, location and age) and attribute value (A) of the broadcast content 511. (Execution program 513) is a computer program for determining whether or not to broadcast the broadcast contents.

The execution content program 51 thus created is directly or temporarily stored, and then transmitted to the transmission unit 1.
02, and is subjected to processing such as modulation and transmitted to the digital broadcasting satellite 30. Note that the broadcasting station 10 may be any broadcasting equipment capable of digital broadcasting. If the user wants to view or listen to the broadcast contents without any restrictions, the content attribute 512 and the execution program 51 are displayed.
3 may be transmitted, and only the broadcast content 511 may be transmitted from the broadcast station 10. Furthermore, broadcast content 51
1 is represented by a character string in FIG. 2 (“Drink at midnight.
Is not limited thereto, but may be any data representation of a type selected by the broadcast content creator, such as images and sounds. For example, it may be a video or music file.

On the other hand, in the receiving section 201 of the receiving apparatus 20,
Broadcast content program 5 transmitted from broadcast station 10
1 is received via the digital broadcast satellite 30, and processing such as demodulation is performed. The contents of the broadcast content 511, the content attribute 512, and the execution program 513 of the broadcast content program 51 demodulated by the reception unit 201 are stored in the broadcast content storage unit 202, the content attribute storage unit 203, and the execution program storage unit 204, respectively. The user attribute storage unit 207 stores the attributes and attribute values of the recipient. As attributes, the user attribute storage unit 20 of FIG.
For example, as shown in the block of FIG.
Location, gender, age and hobby are attribute values of 10
/ 22 / '99 13:00, state A, male, age 25, and classical music.

The time acquisition unit 208 and the location acquisition unit 209 receive the current time and location information transmitted from the GPS satellites 40 by the GPS of the reception unit 201, and store the time and location in the user attribute storage unit 207. The attribute value is written periodically (for example, about every one minute). The GPS is mounted on ordinary car navigation products, and can measure the latitude and longitude of the current position with an accuracy of several meters. Note that the current time may be a time from a clock built in the receiving device. Further, when the receiving apparatus is used only in the same area (for example, area A in FIG. 1) or when the receiving apparatus is used in a fixed manner, the GPS and the current location acquisition unit can be omitted.

Further, the user uses the attribute input unit 210 to input / change attributes and attribute values other than the time and place attributes and attribute values stored in the user attribute storage unit 207 as necessary. And other attributes and attribute values can be added. Note that the time and location attributes and attribute values may be manually changed. The user attribute storage unit 20
The attribute 7 and the attribute value may be respectively stored in a plurality of item tables, and the attribute input unit 210 may select and set an appropriate value from the plurality of attributes and the attribute values.

The execution program engine unit 205 executes the execution program 5 stored in the execution program storage unit 204.
13 is executed. For example, when the execution program 513 is a JAVA program, the execution program engine unit 205 executes the Java program engine (commonly called JAVA program engine).
VIRTUAL MACHINE). The execution program in the execution program storage unit 204 has a processing structure for determining whether the broadcast content in the broadcast content storage unit 202 should always be passed to the reproduction unit 206 or the broadcast content should be discarded without doing so. . In the execution program 513, description of reading of the attribute value of the content attribute storage unit 203 and reading of the attribute value of the user attribute storage unit 207 can be described. However, the values of those attributes cannot be written.

FIG. 4 shows an example of the execution program 513. This is because the value of the location attribute (X, for example, A state and B state) in the content attribute storage unit 203 includes the value (U) of the location attribute in the user attribute storage unit 207, and If the age attribute value (Y) is equal to or less than the age attribute value (V) in the user attribute storage unit 207,
The program engine 205 stores the broadcast content storage unit 20
A description is given of a process of passing the value of 2 to the reproducing unit 206 and discarding the value if not. FIG. 2 specifically shows an example of the attribute value. This user is currently in state A (= U) and is 25 years old (= 18 years or older).
V), the CM of the sake, "The man drinks late at night ..." is reproduced by the reproduction unit 206.

Upon receiving the broadcast content 511, the playback unit 206 plays back the broadcast content in a format corresponding to the format of the broadcast content, and displays the playback image / audio on a display unit (not shown). The receiving unit 2 of the receiving device 20 shown in FIG.
In the case where only the broadcast program 511 and the broadcast content 511 to which the content attribute 512 is not added in FIG.
11 is directly passed to the reproducing unit 206 to reproduce and display the same.
Note that the content attribute 512 in FIG. 3A is a pair of an attribute name and its attribute value in FIG. As for the type of attribute, a set of attribute names is defined in advance, and the existence of the set of attribute names is notified to the receiving device 20 side.

However, as another method, the attribute name is not notified to the receiving device 20 in advance, and the broadcasting station 10 sets an arbitrary attribute name and attribute value. The user may freely set the attribute and the attribute name. In this case, there is a possibility that the same attribute is similar but different attribute names are used. For example, the broadcast station 10 side
The receiving device 20 may use the attribute name “location”, whereas the receiving device 20 may use the attribute name “location”. Then, since the two do not match, the broadcast station 10 side
Even if information indicating that “this broadcast content is the most suitable for a person at location = Atami” is attached to the broadcast content, the receiving apparatus 20 side selects “only the broadcast content at location = Atami”. This broadcast content will not be viewed by this receiver.

However, the greatest merit of this seemingly simple method is that it has an operational advantage that the broadcasting station and the receiving device do not have to define any attribute names in advance. Rather than thinking that broadcast content is one of the few precious resources, if you think that every single broadcast over 24 hours 365 days on more than 100 channels is not so valuable, For example, it may not be possible to obtain a certain percentage of the relevant broadcast content, but it is practical to be able to avoid being restricted by operational constraints. As described above, in FIG. 2 of the present invention, the description of the attribute and the attribute value is based on the premise that the attribute name set between the broadcast station 10 and the receiving device 20 coincides. There are methods and the present invention does not exclude them.

(Embodiment 2) FIG. 5 shows a second embodiment of the broadcast receiving system of the present invention. Once created, the JAVA applet for WWW content can be used for several weeks or months without any change. However, in the case of broadcast content, the length of a commercial is 30 seconds at most. Bundling increases the broadcast capacity and puts a heavy burden on operation. The second embodiment of the present invention solves this.

The differences between the configuration shown in FIG. 5 (Embodiment 2) and FIG. 2 (Embodiment 1) are listed. First, at the broadcasting station 10,
Instead of the broadcast content program 51 and the execution program 513 of FIG. 3A, a simplified broadcast content program 52 and an execution program ID 523 as shown in FIG. 3B can be used. The receiving device 20A of FIG. 5 further includes an execution program ID loading unit 211 and an execution program storage unit 21 in addition to the receiving device 20 of FIG.
2 has been added. The execution program storage unit 212 stores a plurality of pairs of the main body of the execution program and its ID in advance.

In FIG. 5, the broadcast station 10 creates a simplified broadcast content program 52 as shown in FIG. 3 (b) by the broadcast content program creating section 101, broadcasts it via the transmitting section 102, and receives it from the receiving apparatus 20A. When the unit 201 receives the simplified broadcast content program 52, the information inside the program 52 is divided into three, the value of the broadcast content 511 is stored in the broadcast content storage unit 202, and the value of the content attribute 512 (for example, A State / B
(State, 18 years old) is stored in the content attribute storage unit 203, and the value (for example, 2) of the execution program ID 523 is received by the execution program ID loading unit 211. The execution program ID loading unit 211 stores the execution program storage unit 2
12, the value of the received program ID (2)
When an execution program (program 2) that matches with is found, it is passed to the execution program storage unit 204. The subsequent operation is the same as that of the first embodiment shown in FIG. The broadcast receiving system in FIG. 5 can also receive and process the broadcast content program 51 in FIG.

(Embodiment 3) FIG. 6 shows a third embodiment of the broadcast receiving system of the present invention. Differences between the configuration and the like of FIG. 6 (Embodiment 3) and FIG. 5 (Embodiment 2) are listed.
First, in the broadcast station 10, a broadcast program 53 for program transmission shown in FIG. 3C can be used in addition to the broadcast content program 52 shown in FIG. 3B. The broadcast program 53 for transmitting an execution program includes an execution program transmission tag 531, an execution program and its ID.
Of the execution program transmission 532 in which a plurality of pairs are listed. The receiving device 20B of FIG. 6 further includes an execution program fetching unit 213 in the receiving device 20A of FIG.

A broadcast program 53 for transmitting an execution program as shown in FIG. 3C is created by a broadcast content program creating unit 101 of the broadcasting station 10, and is broadcast via a transmitting unit 102. When the receiving unit 201 of the receiving device 20B receives the broadcast program for transmitting an execution program 53, the reception program 201 loads the broadcast program 53 into the execution program capturing unit 213. The execution program capturing unit 213 outputs the execution program transmission tag 5
When the value of “31” is checked and it is determined that this is an execution program transmission tag, the execution program storage unit 212 is emptied and the ID stored in the execution program transmission 532 is stored.
A pair of (= 1 to 4) and the execution program (1 to 4) is stored in the execution program storage unit 212. The operation after the process of storing the ID of the execution program transmission 532 and the execution program in the execution program storage unit 212 and converting the execution program into a cache memory is the same as that of the second embodiment. Note that the broadcast receiving system in FIG. 6 can also receive and process the broadcast content program 51 in FIG.

[0041]

According to the first to third embodiments of the present invention, the broadcaster wants the receiver to view the broadcast content together with the broadcast content sent by the receiver in what situation. Can be specified. In addition, the broadcast content and its execution program are bundled and broadcast, and the receiving device executes the execution program to determine whether to broadcast the bundled broadcast content. Can be dynamically changed according to the situation on the receiving side.

According to the second embodiment of the present invention, a typical execution program is prepared as a kind of cache on the receiving device side, and the broadcasting station sends the execution program itself to the broadcast content program. Instead, only the ID of the execution program to be executed is attached to the broadcast content, and the receiving apparatus can select and execute the execution program to be executed by looking at the ID. It is not necessary to attach the execution program, and only the ID of the execution program needs to be attached, so that the broadcast capacity can be saved and the management can be easily performed.

Further, according to the third embodiment of the present invention, in caching the execution program used in the second embodiment, even if the execution program is not prepared in the receiving device in advance, Since the execution programs can be collectively downloaded by using the broadcast, the reception programs can be easily loaded into the reception device.
