Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information transmission method for transmitting broadcast programs and data, and an information receiving terminal device for receiving broadcast programs and data.

[0002]

2. Description of the Related Art In recent years, digitalization of broadcasting has been advanced.
In this method, a broadcast which has been conventionally transmitted in analog form is replaced with a digital signal compressed by a digital compression method such as MPEG2, and broadcast is performed. Digital modulation technology for transmitting digital signals by analog waves and MPEG2
(Moving Picture Experts Group 2 / (ISO / IEC) 13818)
By combining with digital compression methods such as
More programs can be transmitted using the same frequency band as conventional analog broadcasting, and multi-channel digital satellite broadcasting is being promoted.

[0003] Also, a DSMCC (Digital Storage M) developed as a protocol corresponding to the MPEG2 stream.
edia Command and Control / (ISO / IEC) 13818-6) is for remotely accessing stored audiovisual data, and is stored on digital storage media (DSM: Digital Storage Media) such as CD-ROM and DVD. Although the MPEG data obtained was able to flexibly support interactive applications, a protocol for controlling data access is required in a distributed environment such as a video-on-demand system. The standardized version of this is DSMCC. The representative functions of DSMCC are the following three. User network protocol (UN protocol) User user primitive (UU primitive) Object carousel Object carousel is mainly used for broadcast-type network access, and the hierarchical structure of each program and associated data is periodically changed in a one-way data channel. This is a transmission method for transmitting to the user. The data carousel of BS digital broadcasting in Japan is a user network protocol
(UN protocol) is used. In Japan's BS digital broadcasting, a bandwidth of about 24 Mbps is provided per operator. The bandwidth of 24 Mbps corresponds to approximately one HD (high resolution) broadcast channel,
(Normal resolution) It is also possible to transmit three channels of broadcasting.

Here, HD broadcasting means that the number of pixels is 1920 × 1.
080 is an interlace broadcast having a field frequency of 59.94 Hz and a frame frequency of 29.97 Hz. SD broadcast is a 720 × 480 pixel having a field frequency of 59.94 Hz and a frame frequency of 29.97 Hz.
Is an interlaced broadcast. (Note that SD broadcasts and HD broadcasts have different formats.
It is possible that only two channels of SD broadcast are sent in the band s. )

[0005] PSI (prog) is provided program data.
PMT (Program Map Ta)
ble). PMT is one of the tables constituting PSI, and describes what kind of video, audio, data broadcasting, and subtitles are included in one program. Each of the video, audio, data broadcast, and subtitles (if there are a plurality of them, one of them) is called a component. Each component has a component tag that identifies it. Information in the PMT is described separately for a first loop and a second loop. In the first loop, information about the entire program is written, and in the second loop, information about each component is written.

[0006] In BS digital broadcasting, a data broadcasting program, which is an interactive multimedia service, is broadcast. In the broadcasting of a data broadcasting program, the BML (Br
An oadcast Markup Language (data broadcasting extension markup language) document transmits data broadcasting contents.

[0007] The program to be broadcast is configured, for example, as shown in FIG. That is, a video component 1, an audio component 1, and a data broadcast component 1 are arranged below a single service ID indicating a broadcast channel, and each component is provided with a component tag as shown in FIG. . That is,
The video component 1 has a component tag 0X00, and the audio component 1 has a component tag 0X00.
0X10 is assigned, and the component tag 0X40 is assigned to the data broadcast component 1. Further, as shown in FIG. 1, a BML document (***. Bml) including a startup document (startup.bml) is stored in the component tag 0X40.

Hereinafter, the activation of a data broadcast program will be described with reference to FIG. First of all, it is P
The determination is made based on whether or not the data encoding system descriptor is arranged in the component (entry component) of the tag value 0x40 described first in the second loop of the MT. (Step 1 in FIG. 2) If this is a predetermined value, BML
Judge as a data broadcast program by document. (Step 2 in FIG. 2) Further, auto_start_f of the data encoding system descriptor
lag (step 3 in FIG. 2).
An engine that performs control according to the L document is started (step 4 in FIG. 2). The entry component is included in the entry module (module_id = 0000), and the entry module is transmitted by the data carousel. Since the entry module always includes one startup document, the execution of the startup document is started (FIG. 2).
Step 5). After that, the process is executed according to the BML document, and the BML document is transited as necessary (step 6 in FIG. 2).

Some data broadcasts use or write information written in a non-volatile memory (for example, a flash memory) even when the power of the receiver is turned off. This information includes, for example, a company exclusive region, a company common region, and a viewer residence area region.

First, the contents of the data stored in the broadcaster exclusive area can be used freely for each broadcaster. That is, each broadcasting company has an area where the receiver can freely read and write. This area has 16 fixed-length blocks of 64 bytes per operator.

Next, a description will be given of a method of accessing the area exclusively used by the business operator. BML in BS digital broadcasting
Document data broadcasting is performed, and a BML document is transmitted using a data carousel. In the BML document, control codes for controlling moving images, audio, graphics, and the like constituting data broadcasting are written based on XML.

[0012] There is a part expanded especially for broadcasting.
Its grammar is defined. Use the extended functions readPersistentArray () / writePersistentArray () to access the above-mentioned operator private area. Reading and writing are performed in units of the fixed-length block of 64 bytes. 64-byte fixed-length block 1
The URL of the file name, which is the argument of the above function, is specified by URL and the number of the 6 files and which business operator to use. URL
Has the following format: nvram: // ~ / common / (block numbers 0 to 15 to access which of the 16 blocks) In this case, the broadcaster ID of your own company
Represents reading and writing.

[0013] The broadcaster conducts a questionnaire or the like by, for example, BML broadcasting, and writes viewer information such as the sex, age, preference, and hobby of the viewer into the dedicated area of the broadcaster.

Next, the content of the data stored in the common carrier area is an area which can be read and written in common by all broadcasting businesses. This area has 16 fixed-length blocks of 64 bytes.

The method of accessing the common area of the enterprise is almost the same as the method of accessing the area exclusively for the enterprise, and uses readPersistentArray () / writePersistentArray () as an extension function of BML. The same applies to reading and writing in units of the fixed-length block of 64 bytes. However, U used as a file name that is an argument of the extension function that specifies this
RL is different, and is specified in the format of nvram: // common / (block numbers 0 to 15 of which of the 16 blocks to access). The 16 blocks here include the viewer's name (block 0) and nickname (block 1
-8), address (block 9-10), telephone number (block 11), FAX number (block 12), and the like.

Further, the information stored in the non-volatile memory includes viewer residence area information. This includes a prefectural area code corresponding to the target area descriptor, an area code corresponding to the emergency information signal, and a postal code. The prefectural area code is a code in which one of the 56 bits of bits 0 to 55 is 1, and the prefectural area is indicated by which bit is 1. For example, in Kanagawa Prefecture, bit 14 is 1. The regional code is also a similar 12-bit code, for example, 010101101100 in Kanagawa Prefecture. Postal code is 7
The usual postal code for the digit. Of these, the prefecture code and the region code can be read only from the BML document, and the postal code can be read and written. (Normally, these settings are provided as a function unique to the receiver other than the BML document.) To perform reading / writing, use this extended function readPersistentNumber () / writePersistentNumber () or readPersistentString () / writePersistentString (). Which of the above three information is to be read or written is specified by a URL in a file name which is an argument of these extension functions. The format of the URL is as follows. Nvram: // receiverinfo / prefecture for prefecture code nvram: // receiverinfo / regioncode for region code nvram: // receiverinfo / zipcode for postal code If these information are not set,
readPersistentNumber () is 0, readPersistentString ()
Returns NULL. Flash 11 as described above
One data recording area includes a business-dedicated area, a business common area, and a viewer living area area, and viewer information is stored in the business dedicated area, the business common area, and the viewer living area, respectively. You. Viewer information includes viewer preferences, addresses,
Information such as age, occupation, gender, postal code, and programs viewed by past viewers. Note that these pieces of information are not limited to such an area, but may be stored in an area having an arbitrary nonvolatile memory in the receiver.

[0017]

Conventionally, a data broadcast is received, and at that time, the viewer information is stored in a flash memory or the like, and the viewer is selected from a plurality of pieces of information flowing in the broadcast. In some cases, the user selects information according to the information and displays the information, or connects to an externally connected site such as the Internet to obtain detailed information. For example, JP-A-11-17633. This will be described with reference to FIG. In FIG. 4, there is one data broadcast program, among which data broadcast corresponding to a person who falls into the audience target 1 according to the audience information, and corresponding to a person who falls into the audience target 2. Data broadcasting,
.. Simultaneously broadcasting data broadcasting corresponding to persons classified into the audience target 5. For example, viewer information is classified by age, and data broadcasting for teens, data broadcasting for 20s,... Simultaneously broadcasting data broadcasting for 60s, and actually sending it to flash memory, etc. Is determined according to the age of the viewer stored in the. In order to know more detailed information, each broadcast links to sites on the Internet, and more detailed information can be obtained from each by clicking an icon or the like.

However, recently, the following problems have appeared through the experimental broadcasting of BS digital broadcasting. When broadcasting a plurality of pieces of information and selecting information according to the viewer information from among the pieces of information, a large amount of data broadcasting bandwidth is required to flow the plurality of pieces of information. For example, in BS digital broadcasting, 24 Mbp including all information as shown in FIG.
must be paid within s. Assuming that the data amount to be transmitted in the data broadcast is 5 Mbytes, if the cycle to be transmitted in the data carousel is 10 seconds, the band for data broadcast is 5 MB.
A band of M / 10 × 8 = 4 Mbps is required. Actually, there is an overhead of storing in the data carousel, so a slightly larger bandwidth is required. To transmit a larger amount of data, it is necessary to either increase this band or lengthen the period of the data carousel. However, when the bandwidth is increased, the bandwidth to be allocated to the image is reduced correspondingly, resulting in a problem that the image quality is deteriorated. Further, if the period of the data carousel is lengthened, the average time from when a data acquisition request is issued by a user to when necessary information is acquired increases, and the usability for the user deteriorates.

Conversely, if the data amount is reduced from 5 Mbytes in data broadcasting, the period and band of the data carousel can be reduced, but the information amount of data itself is reduced. For example, you want to introduce all players who originally participated in a certain competition by data broadcasting, but you can only introduce some players, or you want to display the profile of all singers and lyrics of songs in a song program However, the content of data broadcasting becomes poor, as only some singers can do.

Therefore, in the present application, the same information is sent to all viewers in the broadcast, and when there is information that the viewer wants to know in detail, the viewer information is referred to only when the information exists on the Internet. Refers to the URL to which the viewer information is added. If the information is present on the recording medium, the viewer information is classified and stored for each directory, and the URL or directory corresponding to the viewer information is accessed. By doing so, it provides the most detailed information to the viewer.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is a diagram illustrating a configuration example of a receiver. First, a digital signal whose channel has been selected by the tuner 101 is output from a radio wave input from the antenna 100. In digital broadcasting, unlike analog broadcasting, a plurality of broadcasters broadcast on one channel. Therefore, in this tuner, a selection is made in a frequency band and one operator is selected from one frequency band. It is left to the broadcaster to broadcast the HD1 channel or the SD3 channel in one broadcaster as described above.

The digital signal output from the tuner is
Next, it is supplied to the descrambler 102, and the scramble processing is canceled. This is a pay broadcast, etc. If you want to charge, scramble the signal so that you can not watch it as it is, release the scramble process only when a specific card etc. is inserted in the receiver and watch it It is a circuit for enabling it.

The descrambled signal is then supplied to the demultiplex 103. In the demultiplex 103, is the current broadcast an SD broadcast?
D broadcast is identified. Further, the data is divided into video data and audio data, and is temporarily stored in the demultiplexing RAM 120.
4 and the audio decoder 105.

The video decoder 104 decodes (decompresses) the compressed video data, and then superimposes the data of the graphics 121 and outputs it to the monitor as a video output 106. The audio decoder 10
In step 5, the compressed audio data is decoded and output as an audio output 107 by the audio amplifier.

The tuner 101 to the audio decoder 105 are connected to the CPU 108 by a bus, and operate under the control thereof. Bus 2 of CPU 108
00 is an RO for storing other CPU programs.
M109, a RAM 110 for storing variables of the CPU, a flash memory (hereinafter sometimes simply referred to as flash) 111, and the like are connected. The flash 111 stores viewer data such as viewer preference, address, and postal code.

Further, the demultiplex 103 is provided with an SI (service informatio) other than the above audio and video.
n) / PSI information and data carousel information are extracted and temporarily stored in the demultiplexing RAM 120.
EPG (Electronic Prog) for rvice information
ramGuide), extract information of BML document from information of data carousel,
Store in AM110. When the user instructs to display the EPG information, the instruction is presented to the user through the graphics 121. In addition, the BML document is automatically executed or executed by a user's operation. For example, a graphics user interface part in the BML document uses the graphics 121 to present a screen to the user.

The remote controller I / F 112 has a function of transmitting a command to the remote controller and receiving an operation or information from the remote controller when the remote controller 113 only receives an operation of the remote controller 113 and when the remote controller 113 is a remote controller capable of two-way communication. Have. The memory card 114 is a memory card for storing various information and can be removed by a viewer.

The pay-broadcast receiving card 115 is an IC card for generating a key for unlocking the pay-broadcast, which is scrambled when viewing the pay-broadcast. Note that the memory card 114 and the pay broadcast receiving card 115 may be integrated.

The modem 117 is a modem for making a call to the telephone line 118 and performing data communication.

All devices connected to the CPU bus 200 (excluding the CPU 108 itself) are controlled by the CPU 108.

Note that the memory card 11 other than the third embodiment
4 is not required.

Here, the contents of the flash memory 111 will be described in more detail. The data recording area of the flash memory 111 includes the above-described area dedicated to the enterprise, the area common to the enterprise, and the area where the viewer lives. This information is non-volatile information that does not disappear even when the power is turned off because it is a flash memory.

Normally, such viewer information is usually shown in FIG.
Is stored in the flash memory 111. However, as described in claim 3, the memory card 114 is used, and the viewer information may be adapted to the person who is actually watching by exchanging the memory card when the viewer watches. For example, when pointing to a father's memory card and the father is watching, the father's viewer information is stored in the memory card, and the viewer information can be used. When pointing to the mother's memory card and the mother is watching, the mother's viewer information is in the memory card, and the viewer information can be used. Further, this memory card 114 may be the same as an IC card 115 (BCAS card in BS digital broadcasting) for receiving a pay broadcast.

Further, as described in claim 4, the memory may be provided in a remote controller 113 attached to the receiver. In this case, the father has his own remote control for his father, his mother has his own remote control for his mother,
Use it to operate the receiver. When trying to obtain the viewer information, the receiver can also issue a command or the like to the remote controller 113 to obtain the viewer information. In this case, communication between the remote control 113 and the receiver is bidirectional. Also, when the user starts operating the remote control 113, or when a specific button of the remote control 113 is pressed, or every time a button of the remote control 113 is pressed, the viewer information is transmitted from the remote control 113 to the receiver and stored in the RAM or flash. In advance, when the receiver attempts to obtain the viewer information, the information may be obtained from the stored area. Further, the memory in which the viewer information is originally written may be a memory card 116 that can be connected to the remote controller 113 as shown in FIG.

Further, the remote controller 113 is not a normal infrared remote controller, but can be operated through, for example, a telephone, Ethernet (registered trademark), USB or IEEE 1394, or operated using a wireless / mobile phone line. But it is good.

Further, not all of the viewer information is stored in the flash 111, the memory card 114, and the remote controller 113, but a part may be stored in the flash 111 and a part may be stored in the memory card 114.

FIG. 5 shows an embodiment of data broadcasting according to the present invention. FIG. 6 shows an example of a data broadcast screen at this time. In the broadcast shown in FIG. 5, a uniform data broadcast is performed for all viewers. It is assumed that the data broadcast screen at that time is as shown in FIG. In the screen of FIG. 6, it is assumed that this is a commercial of a house maker. In FIG. 6, a button called “details” is displayed at the lower right. When this button is clicked, the viewer's address, postal code, residence area, and the like included in the viewer information are referred to. For example, suppose that this viewer lives in Kanagawa Prefecture. At this time, the detailed content is not broadcasted but exists on a site on the Internet. To the Internet, the modem 11 of FIG.
7 using a dial-up connection. This may be always connected by CATV or ISDN. That is, any system can be used as long as it is connected to a line that can refer to WWW. On the original data broadcast, this site's U
RL for example http://www.jyuutaku-maker-a.co.jp/index.ht
Suppose it was ml. In the case where the user actually accesses the Internet, the residence of the viewer is Kanagawa Prefecture, so that the URL actually accessed in the present embodiment can be set as follows. Example 1 Audience information is described in the URL to limit it. http://www.jyuutaku-maker-a.co.jp/index.html/kanag
awa /.

The data from the site accessed in this way is displayed on the receiver as a screen, for example, as shown in FIG. 7, and the location of the house maker in Kanagawa Prefecture is displayed at the exhibition site of this house maker. Example 2 Audience information is described therein as a URL query.

(Equation 1) In this manner, a plurality of viewer information can be described by describing the query. For example, if you live in Kanagawa and are 70 years old,

(Equation 2) Can be referred to in a more limited form as URL.
In this case, the order on the query

(Equation 3) It is also possible to change as follows. In addition, it is also possible to add all various information registered as viewer information as a query and select and display it on the Internet site side. For example

(Equation 4) = male & zip = 2398550 & tel = 0468364542 & hobby = gardening & f
It is also possible to add a lot of information like avorite-sport = baseball & favorite-meal = raw-fish and select only specific information from among them and display the result. For example, in the above example, there is no relationship between the home exhibition hall and the favorite sport (favorite-sport), so it is possible to display without using it.

At the receiver, the data from the site accessed in this way is displayed on a screen as shown in FIG. 9, for example, and there is an exhibition of barrier-free housing and two-family housing for the elderly at an exhibition hall of this house maker. The locations of things in Kanagawa Prefecture are displayed.

FIG. 8 shows another embodiment of the present invention. The difference from FIG. 3 is that the modem 117 is eliminated and a CD-ROM is used instead.
A drive 119 is provided, and all others are the same. C
The PU 108 accesses the CD-ROM drive 119 through the CPU bus 200 and reads the attached CD-R.
OM data can be read.

In this case, the contents of the data broadcast and the contents of the CD-ROM drive must match. Alternatively, there may be a weekly CD-ROM disc containing all the information on the program of this week, which may be stored for one week. Also, even if it is not a CD-ROM drive,
DVD ROM, DVD RAM, MO, data MD,
Any recording medium such as a floppy (registered trademark), a replaceable HDD, and a tape capable of recording data may be used. Further, the memory card 114 or the remote control memory card 116 has a file directory structure, and may have detailed information therein. Further, although the CD-ROM drive 119 is directly connected to the CPU bus 200, this may be connected through a communication line such as 1394. Assume that the information to be accessed on the original data broadcast is, for example, /jyuutaku-maker-a/index.html. In the case where this is actually accessed via the Internet, the residence of the viewer is Kanagawa Prefecture, and therefore, in the present embodiment, the information to be actually accessed can be, for example, as follows. /jyuutaku-maker-a.co.jp/kanagawa/index.html/ In this way, the CD-ROM 119 is accessed, the information in the CD-ROM 119 is read, and a display is made, for example, as shown in FIG.

The buttons of the detailed contents in FIG. 6 are not in such a format, and detailed information may be displayed by, for example, pressing an icon or a button existing only on the remote controller.

Further, there may be a button for accessing the information while ignoring the information of the viewer. For example, a 60-year-old may present something to his daughter, but ignore the viewer information and search for a product for a 30-year-old woman.

[0045]

According to the present invention, it is possible to reduce the bandwidth required for broadcasting, as compared with the case where a plurality of viewer information is broadcasted simultaneously and detailed information is traced from among them. By allocating minutes to images, high-quality data broadcasting can be performed. Alternatively, there is an advantage that the retransmission cycle on the data carousel can be shortened by reducing the bandwidth, so that it is possible to provide a data broadcast with good responsiveness to the user. In addition, it is possible to appropriately select relevant information required by the viewer, to promptly provide information, and to display the information. Further, by storing the unique information of the viewer in a portable storage medium, It is possible to reproduce the same viewing environment even if the viewing location changes, and by incorporating a storage medium in the remote control that is the operating device, it is possible to reproduce the same viewing environment just by moving with the remote control It has the advantage of being possible.
