Abstract

PROBLEM TO BE SOLVED: To judge viewing limit by a receiving device, and to provide proper content information according to a viewer or the use situation of the viewer by outputting broadcasting data including content information to which viewing attribute indicating a judgment reference for deciding whether or not viewing should be limited is added. SOLUTION: A transmitting device 100 obtains content information, decides and adds viewing attribute, and outputs broadcasting data including the content information to which the viewing attribute is added to a broadcasting medium 110. In this case, the viewing attribute is a numeric value indicating a judgment reference for deciding whether or not the viewing of certain constant amounts of content information should be limited, and the transmitting device 100 decides it, and a receiving device 105 uses it for judging whether or not the viewing of the content information should be limited. Then, the receiving device 105 compares the viewing attribute with reproduction control information held by the receiving device 105 for judging whether or not the viewing should be limited, and reproduces only the content information which is judged as that whose viewing should not be limited.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmitting apparatus, a receiving apparatus, and a broadcasting system, and more particularly, to a technique for providing an optimum program content according to a viewer or a usage state of the viewer.

[0002]

2. Description of the Related Art With the spread of satellite broadcasting and cable television broadcasting in recent years, the contents of programs such as televisions that can be viewed by users are diversifying. However, despite the diversification of program contents, little improvement has been made in the method of selecting and restricting appropriate program contents according to the viewer or the usage status of the viewer. . (Image Reproduction Suppression by Mosaic) FIG. 27 is a diagram showing a configuration of a conventional digital broadcasting system having a parental control function.

[0003] This system is roughly composed of a transmitter 2700 and a receiver 2705. The transmitting device 2700 performs the mosaic processing only on the content information for which the content information is obtained and the viewing is restricted, and transmits the broadcast data including the processed content information to the broadcast medium 2.
708, a content information obtaining unit 2701 that obtains the content information, a viewing restriction determining unit 2702 that determines whether to restrict viewing of the obtained content information, and a mosaic process on the content information that restricts the viewing. Mosaic processing unit 2703 and mosaic processing unit 2
And a broadcast data output unit 2704 that outputs the broadcast data including the content information passed from 703.

[0004] Here, the content information refers to information indicating the content of a broadcasted program itself such as a combination of a still image, a moving image, and a sound. The receiving device 2705 receives broadcast data from the broadcast medium 2708, reproduces the content information, and outputs it as a reproduction output. The broadcast data receiving unit 2706 that receives the broadcast data and the content that is passed from the broadcast data receiving unit 2706 It comprises a reproducing unit 2707 for reproducing information.

FIG. 28 is a flowchart showing an example of the operation of a conventional digital broadcasting system. Here, the operation of broadcasting data output by transmitting apparatus 2700 is shown in FIG.
This will be described with reference to FIG. (1) First, the content information obtaining unit 2701 obtains content information and passes it to the mosaic processing unit 2703 (step S2851).

[0006] (2) Next, the parental level determination unit 2702
It is determined whether or not viewing of the content information input by the content information obtaining unit 2701 is to be restricted (step S2852). (3) If it is determined that the viewing is not restricted, the mosaic processing unit 2703 passes the content information passed from the content information obtaining unit 2701 to the broadcast data output unit 2704 without performing the mosaic process (step S2853).

[0007] (4) If it is determined that viewing is restricted, the mosaic processing unit 2703 sets the content information obtaining unit 2
The content information passed from 701 is subjected to mosaic processing and passed to the broadcast data output unit 2704 (step S28)
54). (5) Next, the broadcast data output unit 2704 outputs the broadcast data including the content information passed from the mosaic processing unit 2703 to the broadcast medium 2708, and subsequently obtains the next content information (step S2855).

Next, the operation of reproducing content information by the receiving apparatus 2705 will be described with reference to FIG. (1) First, the broadcast data receiving unit 2706 transmits the broadcast medium 2
The content information is received from 708 and passed to the reproduction unit 2707 (step S2801). (2) Next, the reproducing unit 2707 sets the broadcast data receiving unit 27
The content information passed from 06 is reproduced (step S2802).

As described above, according to this conventional technique, the program content is restricted by restricting the viewing by the transmitting device.

[0010]

However, in the above-mentioned prior art, since the program content is limited only by the viewing restriction uniformly applied on the transmitting device side, the program content is limited according to the viewer or the usage status of the viewer. There is a problem that appropriate content information cannot be provided. Naturally, on the transmitting device side, it is difficult to judge the age, gender, taste, etc. of the viewer, and even more troublesome, because the viewers are diverse regardless of age and gender, The transmitting device must provide only content information that does not hinder anyone, or provide content information that is appropriate for most viewers but somewhat inappropriate for some viewers. The current situation is that it cannot be obtained.

For example, when the audience includes minors,
Restricting viewing of violence scenes, sex appeal scenes or advertising of alcohol or tobacco, distinguishing content information depending on whether the viewer is male or female, distinguishing content information based on differences in viewer preferences I can't do that. Therefore, the present invention has been made in view of such a problem, and provides a transmitting device, a receiving device, and a broadcasting system that can provide appropriate content information according to a viewer or a usage state of the viewer. The purpose is to:

[0012]

According to the present invention, there is provided a transmitting apparatus for outputting broadcast data including content information, receiving the broadcast data, and reproducing and outputting the content information based on the broadcast data. A transmitting device, the transmitting device comprises: a content information obtaining unit for obtaining content information; and a fixed amount of content information obtained by a fixed amount of content information obtained by the content information obtaining unit. Viewing attribute determining means for determining a viewing attribute indicating a criterion for determining whether or not to restrict viewing; and viewing which adds the viewing attribute determined by the viewing attribute determining means to the content information obtained by the content information obtaining means. Attribute adding means, and a broadcast data output means for outputting broadcast data including content information to which the viewing attribute is added Broadcast data including a certain amount of content information to which a viewing attribute indicating a criterion for determining whether to limit viewing of the content information is added for each certain amount of content information. , A viewing attribute extracting unit that extracts a viewing attribute from the broadcast data received by the broadcast data receiving unit, and a viewing attribute extracted based on the viewing attribute extracted by the viewing attribute extracting unit. Viewing attribute determining means for determining whether to restrict viewing of the added content information; and, if the viewing attribute determining means determines that the viewing is to be restricted, the viewing is performed without reproducing the content information according to the determination. When it is determined that there is no restriction, a selective reproduction unit that reproduces and outputs the content information according to the determination is provided.

This eliminates the need for the transmitting device to determine whether or not to restrict viewing of the content information, and adds a viewing attribute indicating a criterion for determining whether or not to restrict viewing to the content information. The receiving device can determine whether to restrict viewing of the content information. Further, since the receiving device can receive the viewing attribute, it is possible to determine whether or not to restrict the viewing of the content information based on the viewer or the usage status of the viewer and the received viewing attribute.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the digital broadcasting system according to the present invention will be described below in detail with reference to the drawings. (Embodiment 1) FIG. 1 is a diagram showing a configuration of a digital broadcasting system according to Embodiment 1 of the present invention.

The present system is roughly divided into a transmitting device 1
00 and the receiving device 105. Transmission device 10
0 is a content information obtaining unit 101 for obtaining content information, determining and adding a viewing attribute, adding broadcast information including the content information with the viewing attribute added to the broadcast medium 110, and obtaining the content information. A viewing attribute determining unit 102 for determining a viewing attribute for each fixed amount of acquired content information, a viewing attribute adding unit 103 for adding the viewing attribute determined by the viewing attribute determining unit 102 to the obtained content information, and a viewing attribute And a broadcast data output unit 104 for outputting broadcast data including content information to which broadcast information is added.

Here, the viewing attribute refers to a numerical value or the like indicating a criterion for determining whether or not to restrict viewing of a certain amount of content information. Is used to determine whether or not to restrict FIG. 2 is a schematic diagram illustrating a part of the content information input to the transmission device 100.

FIG. 3 is a schematic diagram showing a part of the contents of broadcast data output from transmitting apparatus 100. Here, the broadcast data is broadcast data, and here, as shown in FIG. 3, is composed of a certain amount of block-based viewing attributes and content information. Here, for the sake of simplicity, the value of the viewing attribute is represented by “0” or “1”,
"0" means that the viewing is restricted, and "1" means that the viewing is not restricted.

For example, the content information obtaining unit 101 obtains “content information 1” as indicated by 201 in FIG. 2, and the viewing attribute determining unit 102 sets the value of “viewing attribute 1” of “content information 1” to “1”. The viewing attribute adding unit 103 adds the value “1” of “viewing attribute 1” to “content information 1” as indicated by 301 and 302 in FIG. 3, and the broadcast data output unit 104 Broadcast data having contents as shown in 301 and 302 is output.

Receiving apparatus 105 receives broadcast data from broadcast medium 110, determines whether or not to restrict viewing based on the viewing attribute. Only when it is determined that viewing is not restricted, the receiving apparatus 105 performs the determination. It reproduces and outputs content information, receives broadcast data, and receives a viewing attribute extracting unit 10.
7, a viewing attribute extracting unit 107 that extracts a viewing attribute from the broadcast data and passes it to a viewing attribute determining unit 108, and passes corresponding content information to a selection / playback unit 109, based on the passed viewing attribute. It is determined whether or not viewing of a certain amount of content information to which the viewing attribute has been added is to be restricted, and the determination result is passed to the selection / playback unit 109. Does not play the content information related to the determination,
If it is determined that the viewing is not restricted, the selection / reproduction unit 109 reproduces and outputs the content information related to the determination.

The selection / reproduction unit 109 includes the viewing attribute determination unit 10
In the case where it is determined that the viewing is restricted by No. 8, the content information related to the determination is not passed, and when it is determined that the viewing is not restricted, the content information related to the determination is passed to the playback unit 109b for reproduction. And a reproducing unit 109b for reproducing and outputting the passed content information.

When the viewing attribute determining section 108 determines that the viewing is restricted, the reproduction control section 109a may pass other content information instead of the content information related to the determination. For example, broadcast data having contents as shown in FIG. 3 is received, a value “1” of “viewing attribute 1” 301 is extracted, and it is determined that viewing is not restricted.
“Content information 1” related to the determination of “viewing attribute 1” 302 is reproduced and output. Further, the value “0” of “viewing attribute 2” shown in 303 is extracted, and it is determined that viewing is restricted, and “content information 2” related to the determination of “viewing attribute 2” shown in 304 is not reproduced. Here, "content information 1", which is another content information, may be reproduced and output.

FIG. 4 is a flowchart showing an example of the processing of the digital broadcasting system according to the present invention. here,
The operation of transmitting broadcast data by transmitting apparatus 100 will be described with reference to FIG. (1) First, the content information obtaining unit 101 obtains content information and passes it to the viewing attribute adding unit 103 (step S451). For example, here, “content information 1” as indicated by 201 in FIG.
3

(2) Next, the viewing attribute determining unit 102 determines the viewing attribute for each fixed amount of the content information obtained by the content information obtaining unit 101 and transfers it to the viewing attribute adding unit 103 (step S452). . For example, here, it is assumed that the value of “viewing attribute 1” is determined to be “1” and passed to the viewing attribute adding unit 103. (3) Next, the viewing attribute adding unit 103 adds the viewing attribute determined by the viewing attribute determining unit 102 to the content information and passes it to the broadcast data output unit 104 (step S45).
3). For example, here, as indicated by 301 and 302 in FIG. 3, the value “1” of “viewing attribute 1” is added to “content information 1” and passed to the broadcast data output unit 104.

(4) Next, the broadcast data output unit 104
The broadcast data including the content information to which the viewing attribute added from the viewing attribute adding unit 103 is added is output to the broadcast medium 110, and the next content information is obtained (step S454). For example, here, 30 in FIG.
Broadcast data including “contents information 1” to which a value “1” of “viewing attribute 1” as shown in 1 and 302 is added to the broadcast medium 110, and subsequently, the next data as shown in 202 in FIG. Go to get “contents information 2”.

Next, an operation of reproducing content information by the receiving apparatus 105 will be described with reference to FIG. (1) First, the broadcast data receiving unit 106
The broadcast data is received from 0 and passed to the viewing attribute extraction unit 107 (step S401). For example, 301 and 3 in FIG.
02 is received and passed to the viewing attribute extracting unit 107.

(2) Next, the viewing attribute extracting unit 107 extracts the viewing attribute from the broadcast data passed from the broadcast data receiving unit 106 and passes it to the viewing attribute determining unit 108, and the corresponding content information is reproduced. 109a. (Step S402). For example, the value “1” of “viewing attribute 1” 301 shown in FIG. 3 is extracted and passed to the viewing attribute determining unit 108, and the “contents information 1” 302 shown in FIG.
09a.

(3) Next, based on the viewing attribute passed from the viewing attribute extracting unit 107, the viewing attribute determining unit 108 determines whether or not to restrict viewing, and sends the determination result to the reproduction control unit 109a. hand over. When it is determined that the viewing is not restricted, the reproduction is performed, and when it is determined that the viewing is restricted, the pause reproduction is performed (step S403). For example, here, since the value of “viewing attribute 1” is “1”, it is determined that viewing of “contents information 1” is not restricted, and the determination result is passed to the playback control unit 109a, and playback is performed.

Here, pause playback means outputting a still image, and is realized by repeatedly playing back image data for one screen. In particular, here, when new content information is not passed, a still image is output by repeatedly playing back the content information for one screen that was played back immediately before. (4) If it is determined that the viewing is not restricted, the playback control unit 109a passes the content information passed from the viewing attribute extraction unit 107 to the playback unit 109b, and the playback unit 109b plays back (step S404). For example, here, “contents information 1” is reproduced.

(5) Subsequently, for example, broadcast data having contents as indicated by 303 and 304 in FIG. 3 is received and passed to the viewing attribute extracting unit 107 (step S401). (6) Next, for example, the value “0” of “viewing attribute 2” indicated by 303 in FIG. 3 is extracted and passed to the viewing attribute determining unit 108, and “contents information 2” indicated by 304 is reproduced by the reproduction control unit 1.
09a (step S402).

(7) Next, for example, here, since the value of “viewing attribute 2” is “0”, “content information 2”
Is judged to be restricted, the judgment result is passed to the reproduction control unit 109a, and the reproduction is paused (step S40).
3). (8) If it is determined that viewing is to be restricted, the playback control unit 109a performs pause playback without passing the content information passed from the viewing attribute extraction unit 107 to the playback unit 109b (step S405). For example, here, “contents information 1” reproduced in (4) is pause-reproduced.

For example, in the receiving apparatus 105,
Regardless of whether the viewing attribute value is “0” or “1”, if viewing is not restricted, no viewing restriction is applied. The number of viewing attribute values is not limited to two, and may be any number. As described above, in the present invention, the transmitting device adds a viewing attribute indicating a criterion for determining whether or not to restrict viewing to the content information, and the receiving device determines whether or not to limit viewing based on the viewing attribute. Then, only the content information for which it is determined that the viewing is not restricted is reproduced.

(Embodiment 2) FIG. 5 is a diagram showing a configuration of a digital broadcasting system according to Embodiment 2 of the present invention. It is to be noted that the same components as those of the digital broadcasting system according to the first embodiment are denoted by the same reference numerals, and the description of the same functions will not be repeated. Only the parts unique to the present embodiment will be described.

The present system is roughly divided into a transmitting device 1
00 and a receiving device 505. Transmission device 10
0 has the same configuration as in the first embodiment, and a description thereof will be omitted. FIG. 6 is a schematic diagram showing a part of the content of broadcast data output from transmitting apparatus 100. FIG. 6 has a structure similar to that of FIG. 3, and information stored in the viewing attribute is multi-valued.

Here, for simplicity of explanation, the viewing attribute value and the reproduction control information are represented by natural numbers, and whether to restrict viewing is not limited when the reproduction control information is larger than the viewing attribute value. This means that when the reproduction control information is equal to or less than the viewing attribute value, it means that viewing is restricted. Here, the reproduction control information refers to a numerical value indicating a viewer or a usage state of the viewer, and the like. The reproduction control information is held by the receiving device and compared with the viewing attribute received by the receiving device to view the content information. This is used to determine whether to limit.

For example, the content information obtaining unit 101 obtains “content information 1” as indicated by 201 in FIG. 2, and the viewing attribute determining unit 102 sets the value of “viewing attribute 1” of “content information 1” to “1”. The viewing attribute adding unit 103 adds the value “1” of “viewing attribute 1” to “content information 1” as shown by 601 and 602 in FIG. 6, and the broadcast data output unit 104 Broadcast data having contents such as 601 and 602 is output.

The receiving device 505 further includes a playback control information holding unit 501 for holding playback control information. The viewing attribute determining unit 108 determines that the viewing is not restricted when the playback control information held in the playback control information holding unit 501 is larger than the viewing attribute extracted by the viewing attribute extracting unit 107, and in other cases, It is determined that viewing is restricted.

For example, assuming that the value "3" of the reproduction control information is stored in the reproduction control information holding unit 501 in advance, broadcast data having contents as indicated by 601 and 602 in FIG. The value “1” of “viewing attribute 1” shown at 601 in FIG. 6 is extracted, and the value of “viewing attribute 1” is “1”.
Therefore, since the value “3” of the reproduction control information is larger, it is determined that the viewing of “contents information 1” is not restricted, and “contents information 1” is reproduced. 6 of FIG.
Since the broadcast data having the contents shown in FIGS. 03 and 604 are received, the value “5” of “viewing attribute 2” shown in 603 in FIG. 6 is extracted, and the value of “viewing attribute 2” is “5”. Since the value of the reproduction control information “3” is not larger, it is determined that the viewing of the “contents information 2” is restricted, and the “contents information 1” reproduced immediately before is pause-reproduced.

FIG. 7 is a flowchart showing an example of the processing of the digital broadcasting system according to the present invention. here,
An operation of holding the reproduction control information by the receiving device 505 will be described with reference to FIG. (1) First, the playback control information is held in the playback control information holding unit 501 by a user operation or the like (step S75).
1). For example, here, it is assumed that the value “3” of the reproduction control information is held.

Next, an operation of reproducing content information by the receiving apparatus 505 will be described with reference to FIG.
Here, the reproduction control information holding unit 501 is set in advance.
Holds the value "3" of the reproduction control information. (1) First, the broadcast data receiving unit 106
The broadcast data is received from 0 and passed to the viewing attribute extraction unit 107 (step S701). For example, 601 and 6 in FIG.
02 is received and passed to the viewing attribute extracting unit 107.

(2) Next, the viewing attribute extracting unit 107 extracts the viewing attribute from the broadcast data passed from the broadcast data receiving unit 106, passes the extracted viewing attribute to the viewing attribute determining unit 108, and sends the corresponding content information to the playback control unit. 109a (step S702). For example, the value “1” of “viewing attribute 1” indicated by 601 in FIG. 6 is extracted and passed to the viewing attribute determining unit 108, and “contents information 1” indicated by 602 is reproduced by the reproduction control unit 1.
09a.

(3) Next, the viewing attribute determination unit 108 compares the passed viewing attribute with the reproduction control information to determine whether or not to restrict viewing, and determines the result of the determination as the reproduction control unit 109a.
Pass to. When it is determined that the viewing is not restricted, the reproduction is performed, and when it is determined that the viewing is restricted, the pause reproduction is performed (step S703). For example, here, since the value of “viewing attribute 1” is “1”, it is determined that the viewing of “contents information 1” is not restricted because the value of the reproduction control information “3” is larger, and the determination result is The data is passed to the reproduction control unit 109a and the reproduction is performed.

(4) If it is determined that the viewing is not restricted, the playback control unit 109a passes the content information passed from the viewing attribute extraction unit 107 to the playback unit 109b, and the playback unit 109b plays back (step S704). ). For example,
Here, “contents information 1” is reproduced. (5) Subsequently, for example, broadcast data having contents as indicated by 603 and 604 in FIG.
7 (step S701).

(6) Next, for example, the value “5” of “viewing attribute 2” indicated by 603 in FIG.
08, and “contents information 2” indicated by 604 to the reproduction control unit 109a (step S702). (7) Next, for example, here, since the value of “viewing attribute 2” is “5”, it is determined that the viewing of “contents information 2” is restricted because the value of the reproduction control information “3” is not larger. Then, the result of the determination is transferred to the reproduction control unit 109a, and the pause reproduction is performed (step S703).

(8) If it is determined that the viewing is restricted, the reproduction control unit 109a performs pause reproduction without passing the content information passed from the viewing attribute extraction unit 107 to the reproduction unit 109b (step S705). For example, here, “contents information 1” reproduced in (4) is pause-reproduced. For example, if the value of the reproduction control information is set to “5” or “5 or more” in the receiving device 505, no viewing restriction is imposed in the above case.

Further, the number of pieces of reproduction control information is not limited to one, and some pieces of information can be selectively used according to the viewer or the use situation of the viewer. Furthermore, similarly, a plurality of pieces of reproduction control information can be held, a specific item can be assigned to each piece of reproduction control information, and the viewing can be restricted for each item based on this. Furthermore, although the reproduction control information has been described using a unique value as an example, it is also possible to specify and retain a range and determine whether or not to restrict viewing based on this.

As described above, according to the present invention, the transmitting device adds the viewing attribute indicating the criterion for determining whether or not to restrict the viewing to the content information, and the receiving device holds the viewing attribute and the viewing attribute. By comparing the playback control information with the playback control information, it is determined whether or not the viewing is restricted, and only the content information for which it is determined that the viewing is not limited is reproduced. In addition, the viewing attribute means constituent elements of “video”, “text”, and “audio”, and the content information is separated into video content information, text content information, and audio content information,
The transmitting device outputs the content information with the respective viewing attributes "video", "character", and "sound" added thereto, and the receiving device determines which content information to view based on the viewing attribute. May be selected.

FIG. 8 is a schematic diagram showing a part of the contents of broadcast data output from transmitting apparatus 100 in the above case. As described above, according to the present invention, the transmitting device adds the viewing attribute indicating the component of the content information, and the receiving device compares the viewing attribute with the reproduction control information held in the receiving device, thereby providing the viewing / listening. It is also possible to select a component of the content information to be reproduced and reproduce only the selected component of the content information.

(Third Embodiment) FIG. 1 is a diagram showing a configuration of a digital broadcast system according to a third embodiment of the present invention. This figure is used in the description of the first embodiment. FIG. 9 is a diagram showing components unique to the third embodiment of the digital broadcasting system according to the present invention.

It is to be noted that the same components as those of the digital broadcasting system according to the first embodiment are denoted by the same reference numerals, and the description of the same functions is omitted. Only the parts unique to the present embodiment are described. explain. The viewing attribute determining unit 102 determines the viewing attribute or the download attribute for each fixed amount of the content information obtained by the content information obtaining unit 101.

Here, the download attribute refers to a numerical value or the like indicating that a certain amount of content information is for download, which is determined by the transmitting device, and indicates that the content information is for download by the receiving device. This is used for determination. The viewing attribute adding unit 103 adds the viewing attribute or the download attribute determined by the viewing attribute determining unit 102 to the acquired content information.

The broadcast data output unit 104 outputs broadcast data including content information to which a viewing attribute or a download attribute has been added. As shown in FIG. 9, the reproduction control unit 1
09a includes a playback control switching unit 901 and a content information storage unit 902. The viewing attribute extracting unit 107 extracts a viewing attribute or a download attribute from the broadcast data received by the broadcast data receiving unit 106, and
08 and sends the corresponding content information to the reproduction control unit 10.
Hand over to 9a.

The viewing attribute determining section 108 determines whether or not the attribute passed from the viewing attribute extracting section 107 is a download attribute. If the attribute is a download attribute, the determination result is passed to the reproduction control switching section 901. If not, it is further determined that the attribute passed from the viewing attribute extraction unit 107 is the viewing attribute, and the viewing of a certain amount of content information to which the viewing attribute is added is restricted based on the viewing attribute. It is determined whether or not this is the case, and the determination result is passed to the reproduction control switching unit 901.

When the viewing attribute determining unit 108 determines that the attribute is the download attribute, the reproduction control switching unit 901 passes the content information relating to the determination to the content information storage unit 902, and when it is determined that the attribute is not the download attribute. Further, when it is determined that the viewing is restricted, the content information is acquired from the content information storage unit 902 instead of the content information according to the determination, and the reproduction unit 1
09b, and if it is determined that viewing is not restricted, reproduction is controlled by passing content information relating to the determination.

The content information storage unit 902 stores the content information passed from the reproduction control switching unit 901.
For example, when receiving broadcast data having contents as shown in FIG.
A value “1” of “viewing attribute 1” 301 is extracted, and it is determined that viewing is not restricted. “Content information 1” related to the determination of “viewing attribute 1” 302 is reproduced and output. Further, the value “0” of the viewing attribute 2 shown in 303 is extracted, it is determined that viewing is restricted, and the “content information 2” related to the determination of “viewing attribute 2” shown in 304 is not reproduced. The content information 902 is reproduced and output.

FIG. 10 is a flowchart showing an example of the processing of the digital broadcasting system according to the present invention. Here, the operation of transmitting broadcast data by transmitting apparatus 100 is the same as that of the first embodiment, and therefore description thereof is omitted. Next, an operation of reproducing content information by the receiving device 105 will be described with reference to FIG. It is assumed that the content information in the content information storage unit 902 is stored in the receiving device in advance.

(1) First, the broadcast data receiving unit 106
Broadcast data is received from the broadcast medium 110 and passed to the viewing attribute extracting unit 107 (step S1001). For example, FIG.
The broadcast data having the contents indicated by reference numerals 301 and 302 are received and passed to the viewing attribute extracting unit 107. (2) Next, the viewing attribute extracting unit 107 extracts a viewing attribute from the broadcast data passed from the broadcast data receiving unit 106, passes the extracted viewing attribute to the viewing attribute determining unit 108, and sends the corresponding content information to the playback control switching unit 901. hand over. (Step S100
2). For example, a value “1” of “viewing attribute 1” shown at 301 in FIG.
Is passed to the reproduction control switching unit 901.

(3) Next, the viewing attribute determining section 108 determines whether or not to restrict viewing based on the passed viewing attribute, and passes the determination result to the reproduction control switching section 901. If it is determined that the viewing is not restricted, the viewing attribute extracting unit 10
7 to the playback unit 109b, and if it is determined that viewing is restricted, the content information is acquired from the content information storage unit 902 and passed to the playback unit 109b (step S1003). For example, here, since the value of “viewing attribute 1” is “1”, it is determined that viewing of “content information 1” is not restricted,
The determination result is passed to the playback control switching unit 901, and the content information passed from the viewing attribute extraction unit 107 is passed to the playback unit 10.
Go to 9b to hand it over.

(4) If it is determined that the viewing is not restricted, the playback control switching unit 901 transfers the content information passed from the viewing attribute extraction unit 107 to the playback unit 109b (step S1004). For example, here, “contents information 1” is passed. (5) Next, the playback unit 109b plays back the content information passed from the playback control switching unit 901 (step S10).
06). For example, here, “contents information 1” is reproduced.

(6) Subsequently, for example, broadcast data having the contents indicated by 303 and 304 in FIG. 3 is received and passed to the viewing attribute extracting unit 107 (step S1001). (7) Next, for example, the value “0” of “viewing attribute 2” shown at 303 in FIG. 3 is extracted and passed to the viewing attribute determining unit 108, and the “contents information 2” shown at 304 is reproduced control switching unit 901. (Step S1002).

(8) Next, for example, here, since the value of “viewing attribute 2” is “0”, “content information 2”
Is determined to restrict viewing, and the result of the determination is passed to the playback control switching unit 901, and content information is obtained from the content information storage unit 902 and passed to the playback unit 109b (step S1003). (9) If it is determined that the viewing is restricted, the reproduction control switching unit 901 does not pass the content information passed from the viewing attribute extracting unit 107 to the reproducing unit 109b, but acquires the content information from the content information storage unit 902 and reproduces it. Part 109b
(Step S1005). For example, here, the content information of the content information storage unit 902 is passed.

(10) Next, the playback unit 109b plays back the content information passed from the playback control switching unit 901 (step S1006). For example, here, the content information in the content information storage unit 902 is reproduced. As described above, according to the present invention, the transmitting device adds a viewing attribute indicating a criterion for determining whether to restrict viewing to the content information, and the receiving device determines whether to limit viewing based on the viewing attribute. If it is determined that the viewing is to be restricted, the content of the program is restricted by reproducing the content information stored in advance by the receiving device.

The content information in the content information storage unit 902 is not stored in the receiving device in advance, but is transmitted by the transmitting device via the broadcast medium 110 and received and downloaded by the receiving device. You may. FIG. 11 is a flowchart showing an example of the download processing of the content information of the digital broadcasting system according to the present invention.

Next, the operation of transmitting content information for download by the transmitting apparatus 100 will be described with reference to FIG. FIG. 12 is a schematic diagram illustrating a part of the download content information input to the transmission device 100. FIG. 13 is a schematic diagram showing a part of the content of the broadcast data for download output from transmitting apparatus 100.

(1) First, the content information obtaining unit 101
Obtains the content information and passes it to the viewing attribute adding unit 103 (step S1151). For example, here, FIG.
It is assumed that “download content information 1” as indicated by reference numeral 1201 in FIG. (2) Next, the viewing attribute determining unit 102 determines a download attribute for a certain amount of the content information obtained by the content information obtaining unit 101, and passes it to the viewing attribute adding unit 103 (step S1152). For example, here, FIG.
The value of “download attribute 1” is determined to be “9” for “download content information 1” as indicated by reference numeral 1201 in FIG.

(3) Next, the viewing attribute adding section 103 adds the viewing attribute determining section 10 to the download content information.
The download attribute determined in step S2 is added to the broadcast data output unit 104 (step S453). For example, here, a value “9” of “download attribute 1” as shown by 1301 in FIG.

(4) Next, the broadcast data output unit 104
The broadcast data including the download content information added with the download attribute passed from the viewing attribute adding unit 103 is output to the broadcast medium 110 (step S115).
4). For example, here, 1301 and 130 in FIG.
Broadcast data including “download content information 1” to which “download attribute 1” value “9” as shown in FIG. 2 is added is output to broadcast medium 110.

Next, the operation of storing the download content information by the receiving apparatus 105 will be described with reference to FIG.
This will be described with reference to FIG. (1) First, the broadcast data receiving unit 106
The broadcast data is received from 0 and passed to the viewing attribute extraction unit 107 (step S1101). For example, 1301 in FIG.
, And 1302, and sends it to the viewing attribute extracting unit 107.

(2) Next, the viewing attribute extracting unit 107 extracts the viewing attribute or the download attribute from the broadcast data passed from the broadcast data receiving unit 106, and
08 and sends the corresponding content information to the reproduction control unit 10.
Hand over to 9a. (Step S1102). For example, FIG.
The value “9” of the “download attribute 1” indicated by 1301 is extracted and passed to the viewing attribute determination unit 108, and the “download content information 1” indicated by 1302 is reproduced by the reproduction control unit 10.
Hand over to 9a.

(3) Next, the viewing attribute determining unit 108 determines whether the attribute passed from the viewing attribute extracting unit 107 is a download attribute. If the attribute is a download attribute, the determination result is sent to the reproduction control switching unit 901. Hand over and go to store the content information, and if it is not the download attribute, go to determine whether to restrict viewing (step S110)
3). For example, here, since the value of the passed attribute is “9”, it is determined that the passed attribute is the download attribute, and the determination result is passed to the reproduction control switching unit 901.

(4) If it is determined that the passed attribute is the download attribute, the content information relating to the determination is stored in the content information storage unit 902, and the next broadcast data is received (step S1104). ). For example,
Here, “download content information 1” is stored in the content information storage unit 902, and the next broadcast data is received.

(5) If the passed attribute is not the download attribute, the viewing attribute determining unit 108 determines whether or not to restrict viewing based on the passed viewing attribute, and the determination result is used as a reproduction control switching unit. 901. If it is determined that the viewing is not restricted, the process goes to the case where the viewing is not restricted, and if it is determined that the viewing is restricted, the process goes to the case where the viewing is restricted. The detailed operation is the same as step S1003 in FIG. (Step S1105).

(6) If it is determined that the viewing is not restricted, the processing for the case where the viewing is not restricted is performed. The detailed operation is the same as step S1004 in FIG. 10 described above, and a description thereof will be omitted (step S1106). (7) If it is determined that the viewing is restricted, a process for restricting the viewing is performed. The detailed operation is the same as step S1005 in FIG. 10 described above, and a description thereof will be omitted (step S1107).

(8) Next, the reproduction unit 109b reproduces the content information passed from the reproduction control switching unit 901. For the detailed operation, see step S100 in FIG.
6, the description is omitted (step S110).
8). As described above, according to the present invention, the transmitting device adds in advance the download attribute indicating that the content information is for download, and the receiving device stores the content information based on the download attribute. When the viewing is restricted, the content of the program is restricted by reproducing the content information stored in advance.

(Embodiment 4) FIG. 14 is a diagram showing a configuration of a digital broadcasting system according to Embodiment 4 of the present invention. It is to be noted that the same components as those of the digital broadcasting system according to the second embodiment are denoted by the same reference numerals, and the description of the same functions will not be repeated. Only the parts unique to the present embodiment will be described.

This system is roughly divided into the transmitting device 1
400 and a receiving device 505. Transmission device 1

The viewing attribute determining unit 102 determines the viewing attribute a for each fixed amount of the content information obtained by the content information obtaining unit 101, passes it to the viewing attribute adding unit a103a, and sets the viewing attribute a for each fixed amount of the obtained content information. Is determined and passed to the content information conversion unit 1401 and the viewing attribute addition unit b103b. Content information converter 14
01 converts the content information obtained by the content information obtaining unit 101 into, for example, a mosaic image, a still image, or content information stored in advance, based on the viewing attribute b determined by the viewing attribute determining unit 102. Or the viewing attribute adding unit b103 without any conversion
hand over to b.

The viewing attribute adding section 103 adds a viewing attribute a determined by the viewing attribute determining section 102 to the content information passed from the content information obtaining section 101, and a content information converting section 140.
1 and the viewing attribute determining unit 102
And a viewing attribute adding unit b103b for adding the viewing attribute b determined by the above.

The broadcast data output unit 104 outputs broadcast data including the content information to which the viewing attribute a has been added by the viewing attribute adding unit a103a and broadcast data including the content information to which the viewing attribute b has been added by the viewing attribute adding unit b103b. FIG. 15 for output is a schematic diagram showing a part of the content of broadcast data output from transmitting apparatus 1400.

Here, the viewing attribute indicates the type of conversion of the content information. Here, for simplicity of explanation, the viewing attribute value is represented by a natural number, "1" is the original content information, "2" is the content information converted to a mosaic image, and "3" is the converted to a still image. It means content information. For example, the content information obtaining unit 10
2 obtains “content information 1” as indicated by 201 in FIG. 2, and the viewing attribute determining unit 102 sets the value of “viewing attribute a” of the obtained content information to “1” and the value of “viewing attribute b”. Is determined to be “2”, and the content information conversion unit 1401
Converts the content information obtained because the value of “viewing attribute b” is “2” into a mosaic image, and the viewing attribute adding unit a103a outputs “content information 1a” as shown in 1501 and 1502 in FIG. The value “1” of “viewing attribute 1a” is added to the content “original content information” of “”, and the viewing attribute adding unit b103b outputs the content “mosaic of“ content information 1b ”as shown in 1503 and 1504 in FIG. "Viewing attribute 1b" in "Content information 1 of image"
Is added to the broadcast data output unit 104 in FIG.
5, broadcast data having contents as shown in 1501, 1502, 1503 and 1504.

[0097] The receiving apparatus 505 has the same configuration as that of the second embodiment, and a description thereof will be omitted. Viewing attribute determination unit 108
Selects content information by comparing and determining the viewing attribute passed from the viewing attribute extracting unit 107 with the playback control information held in the playback control information holding unit 501,
The result of the determination is passed to the selective reproduction unit 109. Selective playback unit 1
Reference numeral 09 includes a reproduction control unit 109a that controls reproduction by passing only the content information selected by the viewing attribute determination unit 108 to the reproduction unit 109b, and a reproduction unit 109b that reproduces and outputs the passed content information.

For example, broadcast data having contents as shown in FIG. 15 is received, a value “1” of “viewing attribute 1a” shown in 1501 is extracted, and “content information 1” shown in 1502 is extracted.
a ”is determined to be the original content information,
The value “2” of “viewing attribute 1b” shown in 503 is extracted,
It is determined that the "content information 1b" is the content information of the mosaic image, and the content information to be reproduced is selected, reproduced and output based on the viewing attribute and the reproduction control information.

FIG. 16 is a flowchart showing an example of processing by the transmitting apparatus 1400 of the digital broadcasting system according to the present invention. Here, the operation of broadcasting data output by transmitting apparatus 1400 will be described using FIG. (1) First, the content information obtaining unit 101 obtains content information and passes it to the viewing attribute adding unit a103a and the content information converting unit 1401 (step S1651).
For example, here, it is assumed that “content information 1” as indicated by 201 in FIG. 2 is obtained and passed to the viewing attribute adding unit a103a and the content information converting unit 1401.

(2) Next, the viewing attribute determining unit 102 determines the viewing attribute a for each fixed amount of the acquired content information and transfers it to the viewing attribute adding unit a103a. Is determined and passed to the content information conversion unit 1401 and the viewing attribute addition unit b103b. (Step S1652). For example, here
The value of “viewing attribute 1a” is determined to be “1” and passed to the viewing attribute adding unit a103a, and the value of “viewing attribute 1b” is determined to be “2” to the content information selecting unit 1803 and the viewing attribute adding unit b103b. Shall pass.

(3) Next, the viewing attribute adding unit a103a
Adds the viewing attribute a determined by the viewing attribute determining unit 102 to the content information and passes the content information to the broadcast data output unit 104 (step S1653). For example, here, FIG.
As indicated by Nos. 1501 and 1502 of No. 5, the value “1” of the “viewing attribute 1a” is added to the content “original content information 1” of the “content information 1a” and passed to the broadcast data output unit 104.

(4) Next, the content information converter 140
1 determines whether or not the value of the viewing attribute b determined by the viewing attribute determining unit 102 indicates the original content information (step S1654). For example, here, since the value of the determined “viewing attribute 1b” is “2”, it is determined that it does not mean the original content information.

(5) If it is determined that the value of the viewing attribute b does not mean the original content information,
Further, it is determined whether or not the content information indicates content information converted into a mosaic image (step S1656). For example, in this case, since the value of the determined “viewing attribute 1b” is “2”, it is determined to mean content information converted into a mosaic image.

(6) When it is determined that the value of the viewing attribute b means the content information converted into a mosaic image, the content information conversion unit 1401 converts the original content information into a mosaic image and views it. The attribute is passed to the attribute adding unit b103b (step S1657). For example, here, “contents information 1” is converted into a mosaic image and passed to the viewing attribute adding unit b103b.

(7) Next, the viewing attribute adding section b103b
Adds the viewing attribute b determined by the viewing attribute determining unit 102 to the content information passed from the content information converting unit 1401 and passes the content information to the broadcast data output unit 104 (step S1659). For example, here, 150 in FIG.
3 and 1504, the content "content information 1b" includes "viewing attribute 1" in the content "mosaic image content information 1".
The value “b” is added to the broadcast data output unit 104.

(8) Next, the broadcast data output unit 104
Viewing attribute adding unit a103a and viewing attribute adding unit b103
b. The broadcast data including the content information to which the viewing attribute passed from b is added is output to the broadcast medium 110.
Go to get the next content information (step S166)
0). For example, here, 1501 and 150 in FIG.
2, 1503 and 1504, "viewing attribute 1
“Content information 1a” to which the value “1” of “a” is added “Content information 1b” to which the value “2” of “original content information 1” and “viewing attribute 1b” are added
2 is output to the broadcast medium 110, and then the broadcast data including the content “mosaic image content information 1” is output to the broadcast medium 110.
2 to obtain the next “content information 2”.

(9) Subsequently, for example, “content information 2” as shown by 202 in FIG. 2 is obtained and passed to the viewing attribute adding unit a103a and the content information converting unit 1401 (step S1651). (10) Next, for example, the value of “viewing attribute 2a” is set to “1”.
Is passed to the viewing attribute adding unit a103a, the value of the “viewing attribute 2b” is determined to be “2”, and is passed to the content information conversion unit 1401 and the viewing attribute adding unit b103b. (Step S1652).

(11) Next, for example, 1505 in FIG.
And 1506, the content of “content information 2a” and “viewing attribute 2”
The value “1” of “a” is added and passed to the broadcast data output unit 104. (Step S1653). (12) Next, for example, since the value of the determined “viewing attribute 2b” is “1”, it is determined to mean the original content information. (Step S1654).

(13) If the value of the viewing attribute b means the original content information, the content information converting unit 1401 passes the original content information to the viewing attribute adding unit b103b without converting it (step). S1655). For example, here, “content information 2” is passed to the viewing attribute adding unit b103b without conversion. (14) Next, for example, 1507 and 1508 in FIG.
As shown in the figure, the value “1” of the “viewing attribute 2b” is added to the content “original content information 2” of the “content information 2b”.
To the broadcast data output unit 104. (Step S1659).

(15) Next, for example, at 150 in FIG.
As shown in 5, 1506, 1507, and 1508, the contents of “content information 2a” to which the value “1” of “viewing attribute 2a” is added “the original content information 2” and the value “1” of “viewing attribute 2b” Is output to the broadcast medium 110 including the content “original content information 2” of the “content information 2b” to which
The next “content information 3” as indicated by 203 in FIG. 2 is obtained (step S1660).

(16) Subsequently, for example, “contents information 3” as shown at 203 in FIG. 2 is obtained and passed to the viewing attribute adding unit a103a and the contents information converting unit 1401 (step S1651). (17) Next, for example, the value of “viewing attribute 3a” is set to “1”.
Is passed to the viewing attribute adding unit a103a, the value of the “viewing attribute 3b” is determined to be “3”, and is passed to the content information converting unit 1401 and the viewing attribute adding unit b103b. (Step S1652).

(18) Next, for example, 1509 in FIG.
As shown in FIGS. 1510 and 1510, the content “original content information 3” of “content information 3a” includes “viewing attribute 3”.
The value “1” of “a” is added and passed to the broadcast data output unit 104. (Step S1653). (19) Next, for example, since the value of the determined “viewing attribute 3b” is “3”, it is determined that it does not mean the original content information. (Step S1654).

(20) Next, for example, since the value of the determined “viewing attribute 3b” is “3”, it is determined that it does not mean the content information converted into the mosaic image. (Step S1656). (21) If it is determined that the value of the viewing attribute b does not mean the content information converted into the mosaic image, the content information conversion unit 1401 converts the original content information into a still image, and converts the original content information into a still image. (Step S1658). For example, here, the “content information 3” is converted into a still image and the viewing attribute adding unit b1 is converted.
Hand over to 03b.

(22) Next, for example, 1511 in FIG.
1515, the value “3” of the “viewing attribute 3 b” is added to the content “content information 3 of the still image” of the “content information 3 b” and passed to the broadcast data output unit 104.
(Step S1659). (23) Next, for example, 1509, 1510 in FIG.
As shown in 1511 and 1512, the contents of “content information 3a” to which the value “1” of “viewing attribute 3a” is added “original content information 3” and “viewing attribute 3”
The broadcast data including the content “still image content information 3” of the “content information 3b” to which the value “3” of the “b” is added is output to the broadcast medium 110, and subsequently, the next content information is obtained ( Step S1660).

FIG. 17 is a flowchart showing an example of processing by the receiving device 505 of the digital broadcasting system according to the present invention. Next, an operation of reproducing content information by the receiving device 505 will be described with reference to FIG. Here, it is assumed that the value “2” of the reproduction control information is stored in the reproduction control information holding unit 501 in advance.

(1) First, the broadcast data receiving unit 106
Broadcast data is received from the broadcast medium 110 and passed to the viewing attribute extracting unit 107 in units of logical blocks (step S1).
701). Here, a logical block refers to a fixed amount of broadcast data in which all pieces of content information and its attributes at the same time are one unit. For example, 150 in FIG.
Broadcast data of “logical block 1” having contents as shown in 1, 1502, 1503 and 1504 is received and passed to the viewing attribute extracting unit 107.

(2) Next, the viewing attribute extracting unit 107 extracts an unprocessed viewing attribute from the broadcast data passed from the broadcast data receiving unit 106 and passes it to the viewing attribute determining unit 108.
The corresponding content information is passed to the reproduction control unit 109a.
(Step S1702). For example, first, 15 in FIG.
The value “1” of the “viewing attribute 1a” shown in FIG. 01 is extracted and passed to the viewing attribute determining unit 108, and the “contents information 1a” shown in 1502 is passed to the reproduction control unit 109a.

(3) Next, the viewing attribute determining section 108 compares the passed viewing attribute with the reproduction control information to determine whether or not to view, and passes the determination result to the reproduction control section 109a. If it is determined that the viewing is not to be performed, it is determined whether or not the extraction of the viewing attribute in the logical block related to the processing is completed. If it is determined that the viewing is to be performed, the viewing attribute extracting unit 10 is determined.
7 is passed to the reproduction unit 109b (step S1703). For example, here, since the value of “viewing attribute 1a” is “1”, it is determined that the viewing is not performed because the value does not match the value “2” of the reproduction control information, and extraction of the viewing attribute in the logical block related to the processing is performed. Go to determine if completed.

(4) If it is determined that the viewing is not to be performed, it is determined whether or not the extraction of the viewing attribute in the logical block related to the processing has been completed. If it is determined that the processing has been completed, the original content information is sent to the playback unit 109b,
If it is determined that the process has not been completed, the process proceeds to extraction of the next viewing attribute (step S1704). For example, here
Since the extraction of the viewing attribute in the logical block related to the processing has not been completed, the process proceeds to the extraction of the next viewing attribute.

(5) Next, for example, the value “2” of “viewing attribute 1b” shown at 1503 in FIG. 15 is extracted and passed to the viewing attribute determining unit 108, and “contents information 1” shown at 1504 is extracted.
b ”to the reproduction control unit 109a (step S170).
2). (6) Next, for example, since the value of “viewing attribute 1b” is “2”, it is determined that viewing is to be performed because it matches the value “2” of the reproduction control information, and passed from the viewing attribute extracting unit 107. The "contents information 1b" is transferred to the reproducing unit 109b (step S1703).

(7) If it is determined that the content is to be viewed, the playback control unit 109a passes the content information related to the determination passed from the viewing attribute extraction unit 107 to the playback unit 109b (step S1706). For example, the content “content information 1 of mosaic image” of “content information 1b” shown in 1504 is passed to the reproduction unit 109b. (8) Next, the reproduction unit 109b reproduces the content information passed from the reproduction control unit 109a (Step S170)
7). For example, “content information 1b” shown in 1504
Is reproduced as “content information 1 of mosaic image”.

(9) Subsequently, for example, at 150 in FIG.
The broadcast data of “logical block 2” having contents as shown in 5, 1506, 1507 and 1508 is received and passed to the viewing attribute extracting unit 107 (step S1701). (10) Next, for example, first, the value “1” of “viewing attribute 2a” shown in 1505 in FIG. 15 is extracted and passed to the viewing attribute determining unit 108, and the corresponding “content information 2a” shown in 1506 is reproduced. Transfer to the control unit 109a (Step S17)
02).

(11) Next, for example, “viewing attribute 2a”
Is "1", it does not match the value "2" of the reproduction control information, so that it is determined that the viewing is not performed, and it is determined whether or not the extraction of the viewing attribute in the logical block related to the processing is completed ( Step S1703). (12) Next, for example, since the extraction of the viewing attributes in the logical block related to the processing has not been completed, the process proceeds to the extraction of the next viewing attributes (step S1704).

(13) Next, for example, 1507 in FIG.
The value “1” of the “viewing attribute 2b” shown in “1” is extracted and passed to the viewing attribute determining unit 108, and the “contents information 2b” shown in 1508 is passed to the reproduction control unit 109a (step S170).
2). (14) Next, for example, the value of “viewing attribute 2b” is “1”
Therefore, it is determined that the viewing is not performed because the value does not match the value “2” of the reproduction control information, and it is determined whether or not the extraction of the viewing attribute in the logical block related to the processing is completed (step S1703).

(15) Next, for example, here, since the extraction of the viewing attributes in the logical block related to the processing has been completed, the original content information is transferred to the reproducing unit 109b (step S1704). (16) If it is determined that the extraction of the viewing attribute has been completed, the playback control unit 109a passes the original content information passed earlier from the viewing attribute extraction unit 107 to the playback unit 109b (step S1705). For example, here, “contents information 2a” is passed.

(17) Next, for example, here, “contents information 2a” is reproduced (step S1707). Although the content information is converted into a mosaic image or a still image here for simplicity of description, the conversion processing method may be arbitrarily determined for each value of the viewing attribute.

Although the broadcast data includes the original content information and the converted content information one by one, the converted content information may be plural. Furthermore, although the reproduction control information has been described using a unique value as an example, it is also possible to specify and retain a range and select content information based on the range. As described above, according to the present invention, the transmitting device adds the viewing attribute indicating the type of conversion of the content information to the original content information and the converted content information, and the receiving device holds the viewing attribute and the receiving attribute. The content information is selected and reproduced by comparing the reproduction information with the reproduction control information.

Further, a content information selection unit 1803 is provided.
The content information obtaining unit 101 includes a first content information obtaining unit 1801 and a second content information obtaining unit 1802.

The first content information obtaining unit 1801
The content information is obtained and passed to the viewing attribute adding unit a103a and the content information selecting unit 1803. The second content information obtaining unit 1802 obtains the second content information,
The content information is passed to the content information selection unit 1803.

2411, 2412, 2413, 2414 and 2415
Then, the broadcast data to which the multiplex attribute is added as shown in FIG.

It is also possible to make a selection different from the above example using values other than the above multiple attributes (step S).
2561). For example, only the second broadcast data, only the third broadcast data, and the second broadcast data and the third broadcast data can be selected. FIG. 26 is a flowchart illustrating an example of processing by the receiving device 2205 of the digital broadcasting system according to the present invention.

Next, the operation of reproducing content information by the receiving apparatus 2205 will be described with reference to FIG. Here, it is assumed that the value “2” of the reproduction control information is stored in the reproduction control information holding unit 501 in advance. (1) First, the broadcast data receiving unit 106
The broadcast data is received from 0 and passed to the multiple attribute determination unit 2206 in logical block units (step S2601).
For example, broadcast data of “logical block 2” having contents as shown in 2406, 2407 and 2408 in FIG. 24 is received and passed to the multiple attribute determination unit 2206.

(2) Next, the multiple attribute determination unit 2206
Based on the multiplex attribute in the broadcast data passed from the broadcast data receiving unit 106, it is determined whether or not the broadcast data is multiplexed. When it is determined that the broadcast data is not multiplexed, the content information of the broadcast data is delivered, and when it is determined that the broadcast data is multiplexed, the viewing attribute is extracted (step S2602). For example, since the value of “multiplex attribute 2” shown in 2406 is “1”, it is determined that the logical block is not multiplexed, and the content information of the broadcast data is passed.

(3) If it is determined that the broadcast data has not been multiplexed, the reproduction control unit 109a transfers the content information of the broadcast data to the reproduction unit 109b (step S260).
3). For example, “content information 2a” shown in 2408
Is passed to the reproduction unit 109b. (4) Next, the reproduction unit 109b reproduces the content information passed from the reproduction control unit 109a (Step S260)
8). For example, here, the content “first content information 2” of “content information 2a” shown in 2408 is reproduced.

(5) Subsequently, for example, at 240 in FIG.
9, 2411, 2412, 2413, 2414 and 24
The broadcast data of “logical block 3” having the content shown in FIG. 15 is received and passed to the multiple attribute determination unit 2206 (step S2601). (6) Next, for example, since the value of “multiplex attribute 3” shown in 2409 is “3”, it is determined that the logical block is multiplexed, and the viewing attribute is extracted (step S260).
2).

(7) If it is determined that the broadcast data is multiplexed, the viewing attribute extracting unit 107 extracts an unprocessed viewing attribute from the broadcast data and passes it to the viewing attribute determining unit 108.
The corresponding content information is passed to the reproduction control unit 109a.
(Step S2604). For example, first, 24 in FIG.
The value “1” of the “viewing attribute 3a” shown in 10 is extracted and passed to the viewing attribute determining unit 108, and the “contents information 3a” shown in 2411 is passed to the reproduction control unit 109a.

(8) Next, the viewing-attribute determining unit 108 compares the passed viewing-attribute with the reproduction control information to determine whether or not to view, and passes the determination result to the reproduction control unit 109a. If it is determined that the viewing is not to be performed, it is determined whether or not the extraction of the viewing attribute in the logical block related to the processing is completed. If it is determined that the viewing is to be performed, the viewing attribute extracting unit 10 is determined.
7 is passed to the reproduction unit 109b (step S2605). For example, here, since the value of the “viewing attribute 3a” is “1”, it is determined that the viewing is not performed because the value does not match the value “2” of the reproduction control information, and extraction of the viewing attribute in the logical block related to the processing is performed. Go to determine if completed.

(9) If it is determined that the viewing is not to be performed, it is determined whether or not the extraction of the viewing attribute in the logical block related to the processing has been completed. If it is determined that the processing has been completed, the first content information is transferred to the reproducing unit 109b. If it is determined that the processing has not been completed, the next viewing attribute is extracted (step S2606). For example, here, since the extraction of the viewing attribute in the logical block related to the processing has not been completed, the process proceeds to the extraction of the next viewing attribute.

(10) Next, for example, 2412 in FIG.
The value “2” of the “viewing attribute 3b” shown in FIG. 3 is extracted and passed to the viewing attribute determining unit 108, and the “content information 3b” shown in 2413 is passed to the reproduction control unit 109a (step S260).
4). (11) Next, for example, the value of “viewing attribute 3b” is “2”
Therefore, it is determined that the content is to be viewed because it matches the value of the reproduction control information “2”, and the “contents information 3b” passed from the viewing attribute extraction unit 107 is passed to the reproduction unit 109b (step S2605).

(12) If it is determined that viewing is to be performed,
The reproduction control unit 109a passes the content information related to the determination to the reproduction unit 109b (Step S2603). For example, the content “second content information 3” of “content information 3b” indicated by 2413 is passed to the reproduction unit 109b. (13) Next, for example, the content “second content information 3” of the “content information 3b” indicated by 2413 is reproduced (step S2608).

[0170] If it is determined in step S2606 that the extraction of the viewing attribute in the logical block related to the processing has been completed, the reproduction control unit 109a causes the reproduction unit 10a to execute the processing.
The first content information previously passed from the viewing attribute extraction unit 107 is passed to 9b (step S2607). For example, the value “3” of the reproduction control information is stored in the reproduction control information holding unit 501 in advance, and 2401 and 240 in FIG.
When the broadcast data of “logical block 1” having the contents shown in 2, 2,403, 2404, and 2405 is received, the value of “viewing attribute 1a” is “1” and the value of “viewing attribute 1b” is Since it is “2”, it does not coincide with the value “3” of the reproduction control information, so it is determined in step S2606 that the extraction of the viewing attribute in the logical block related to the processing has been completed, and the reproduction control unit 109a Is the playback unit 1
09b passed from the viewing attribute extraction unit 107 earlier
Content information 1 "is passed.

Although the viewing attribute is determined here to restrict viewing, it may be determined to view additional content information such as a replay video of a sports program or commentary audio of a news program. . Further, the content information to be input or selected is the first content information, the second content information, and the third content information. However, four or more content information may be input.
There may be more than one.

Furthermore, although the reproduction control information is exemplified by a unique value, a range can be designated and held, and content information can be selected based on this. In this way,
According to the present invention, the transmitting device selects a plurality of pieces of content information by adding a viewing attribute indicating the type of the content information, and further determines the number of pairs of the viewing attribute and the content information to be multiplexed into a certain amount of logical blocks. The receiving apparatus selects and reproduces the content information by adding the indicated multiple attribute and comparing the viewing attribute based on the multiple attribute or the reproduction control information held in the receiving apparatus.
