Description

Broadcasting broadcasting method of data broadcasting system, receiving system in data broadcasting system, multicasting system and multicasting system

The present invention relates to a data broadcasting system, a receiving system in a data broadcasting system, a multicasting system, and a broadcast program (broadcast program such as news, drama, sports, quiz, etc. produced for broadcasting) of a multicasting system.

FM multicasting broadcasts voice, text, graphics, etc. with stereo voice. In other words, a voice, a character, and a figure are multiplexed and broadcasted in a normal FM broadcast.

Representative examples of the FM multicasting standard are three methods: a data radio channel (DARC), a fixed reception method, and a radio data system (RDS). Among these, DARC is the newest and is adopted as an international standard. DARC is described in accordance with Recommendation 807 "Reference Model for Data Broadcasting" of the International Telecommunication Union (ITU-R).

DARC converts a character or a figure into digital information, modulates a subcarrier frequency of 76 kHz, frequency multiplexes into a stereo baseband signal, and FM modulates the broadcast.

Fig. 16 shows a hierarchical structure showing a character / shape coding system of DARC.

In Layer 1, transmission path characteristics are specified. Multiple signals are superposed on the higher frequency side than the L + R signal and the L-R signal, which are ordinary FM stereo broadcast signals. This superposition method adopts the LMSK (Level Controlled Minimum Shift Keying) method in which the level of the multiple signal is controlled by the modulation degree of the L-R signal in consideration of the fact that the disturbance to the multiple signal or the audio signal becomes remarkable when the speech modulation degree is small.

Layer 2 defines a frame structure of data, including an error correction scheme. Each frame consists of 272 blocks in the column direction, and a 16-bit block identification code (BIC) is added at the beginning, and frame synchronization and block synchronization are performed based on this block identification code. Among the 272 blocks in the column direction, 190 blocks are packets for transmitting data, and 82 blocks are parity packets for transmitting parity in the column direction. Each packet is composed of a 176-bit data portion in the row direction, a 14-bit cyclic redundancy code (CRC) that is an error detection code, and a parity portion of 82 bits.

In the transmission data, error correction is first performed in this hierarchical step based on this one frame. 17. In reality, as shown in Fig. 17, transmission data is transmitted in a frame structure in which packets and parity packets are arranged in a predetermined order in the longitudinal direction.

Layer 3 defines the composition of data packets. The data packet consists of 176 bits excluding BIC, CRC, and parity among each row in the frame. A data packet consists of a prefix and a block of data.

Layer 4 shows the organization of data groups. A data group consists of one or more data blocks. This data group also includes a CRC, which is an error detection code, and error detection is performed even in this layer of the transmitted data. One data group corresponds to one page of data.

Layer 5 defines the configuration of one piece of integrated information transmitted by FM multicasting, that is, broadcast profile.

Fig. 18 shows the structure of the data packet of layer 3.

The prefix in the data packet contains the service identification code. As shown in Table 1, this service identification code consists of four bits of b1 to b4, and identifies broadcast program contents (general information, traffic information, additional information, auxiliary information, operation signals).

Table 1

Fig. 19 shows the structure of the broadcast profile of Layer 5.

The broadcast pro data is composed of a plurality of data groups. The first group is broadcast program management data including information on the entire broadcast program, such as the broadcast program number and the total number of pages. Groups after the second are page data. Each page data contains data for each page.

The broadcast pro management data is composed of a broadcast pro data header and a data unit (data unit group) of one or a plurality of broadcast pro management data. Each page data is composed of a page data header and a data unit (data unit group) of one or a plurality of page data.

20 shows the structure of a broadcast profile header.

The broadcast pro data header consists of a data header identifier and data header data. The data header data consists of the broadcast pro number, the total number of pages, the presentation function, the information type, the display format, and the broadcast pro content update flag.

The broadcast pro number consists of 8 bits and represents the broadcast pro number as a binary value. The broadcast pro number is 0-255. That is, up to 256 types of broadcast programs can be broadcasted on one service identification code (see Fig. 18).

The broadcast pro content update flag consists of 2 bits and indicates the update of the broadcast pro unit. Each update is incremented by two bits. That is, it repeats as 00 → 01 → 10 → 11 → 00.

The total number of pages is 6 bits, and the number of pages constituting the broadcast program is represented by a binary value. The total number of pages excluding broadcast pro management data is displayed. If the total number of pages is from 0 to 63, and the total number of pages is 0, there is no page data. That is, the maximum number of pages of one broadcast program is 63.

The presentation function consists of 8 bits and indicates the type of code and the type of presentation included in the broadcast program. The information type consists of 4 bits and identifies the genre of broadcast program contents. The display format consists of 4 bits and specifies the display mode.

Fig. 21 shows the configuration of a data unit of broadcast pro management data.

The data unit of broadcast pro management data includes a data unit identification code indicating the type of data unit, a data unit link flag (DUL) indicating a connection between data units, a data unit size indicating a data unit length, and a data unit length indicating a data unit length. Contains data unit data consisting of data.

Fig. 22 shows the structure of the page data header.

The page data header consists of a data header identifier and data header data. The data header data consists of a broadcast program number, page number, presentation function, information type, display format, and page content update flag.

The broadcast pro number, the presentation function, the information type and the display format are the same as the broadcast pro number, the presentation function, the information type and the display format of the broadcast pro data header.

The page content update flag consists of 2 bits and represents the update of the content for each page. Each update is incremented by two bits. That is, it repeats as 00 → 01 → 10 → 11 → 00.

The page number consists of 6 bits and represents the page of the broadcast program as a binary value. The presentation function consists of 8 bits and indicates the type of code and the type of presentation included in the broadcast program.

Fig. 23 shows the configuration of a data unit of page data.

The data unit of the page data includes a data unit identification code indicating the type of data unit, a data unit link flag (DUL) indicating a connection between data units, a data unit size indicating a data unit length, and a number of data represented by the data unit length. Contains data unit data consisting of data.

The present applicant has progressed the development of a broadcast program of FM multicasting which is compatible with DARC, which is an FM multicasting standard, and which is different from the broadcast program of FM multicasting currently being performed. For example, a quiz broadcast program relating to the progress of a sports broadcast program provided by a broadcast other than multicast such as television broadcast or FM broadcast is broadcast in real time in FM multicast. At this time, both the broadcast program execution program for executing the broadcast program and the broadcast program configuration data (data such as text, graphics, and voice) constituting the broadcast program are transmitted by FM multicast.

The user inputs the answer to the quiz presented by the quiz broadcasting program, and then broadcasts the correct answer through FM multicasting. The answer result is recorded in a card or the like at the receiving terminal, and the user presents the card to a convenience store so that the user can receive a predetermined service.

For example, when a music broadcaster is broadcasted on a radio broadcast, the question "Who is the singer who sings this song?" By FM multiplex and "(1) singer name 1, (2) singer name 2 , (3) Singer Name 3 "is displayed.

Or, if baseball broadcaster is being broadcasted on TV, the question is "Can batters be on base" by FM multicast and the choice of "(1) hit, (2) home run, (3) out" Mark the item.

It is also conceivable to broadcast a quiz broadcast program that is not related to broadcasts other than multicast by FM multicast.

As a problem when performing such FM multicasting, there have been the followings.

(a) Providing in multicast a broadcast program executed by a broadcast program. In particular, the broadcast program of the contents related to the progress of the broadcast program of a broadcast other than the multicast should be provided by the multicast.

(b) Increase the number of broadcasters. In the past, the maximum number of broadcast programs was 255.

(c) The number of data on one screen is at least good, but increase the number of screens in one broadcast program. Conventionally, one page data = one screen data, and the maximum number of screens of one broadcast program was 63 screens.

(d) An advertisement program comprising a plurality of advertisement screens is transmitted in advance and stored in the terminal, and a predetermined number of advertisement screens are inserted and displayed behind a predetermined screen displayed on another broadcast program. In other words, the screen of another broadcast program is inserted behind the screen displayed by a certain broadcast program.

An object of the present invention is to provide a data broadcasting system capable of providing a broadcast program executed by a transmitted program and a reception system in the data broadcasting system.

An object of the present invention is to provide a broadcast program broadcast method of a multicast system and a multicast system capable of providing a broadcast program executed by a program transmitted by multicast.

In addition, the present invention is a broadcast program of the broadcast program of the broadcast program to be executed by the broadcast program and can simultaneously provide a broadcast program of the contents related to the progress of the broadcast program of the broadcast other than the multicast broadcast in a multicast system and a multicast system. It is an object to provide a broadcasting method.

Mark on. If the selected broadcast program is a program-type broadcast program including a program in broadcast program data, the CPU 50 executes the broadcast program according to the program.

[3] data packets and broadcast profile

As described above, the service identification code is included in the prefix (see Fig. 18) in the data packet. Particular FM code with the service identification code for the multiple broadcast is already assigned to a common FM multiplex broadcasting (see Table 1) different from the code, for instance "0111} (= 7 _H) is assigned. Therefore, a particular FM multiplex broadcasting The service identification code in the prefix in the data packet for the broadcast pro is " 0111 &quot;.

As described above, the broadcast pro data (see Fig. 19) is composed of broadcast pro management data and one or a plurality of page data. The broadcast pro management data is composed of a broadcast pro data header and a data unit of one or a plurality of broadcast pro management data. The page data consists of a page data header and a data unit of one or a plurality of page data. As described above, in the broadcast pro data header (see Fig. 20) and the page data header (see Fig. 22), information types for genre identification of broadcast program contents are included.

For the specific FM multicasting, the information type is assigned a code different from the code already assigned to the general FM multicasting, for example, "0010" (= _2H ). Therefore, the information type in the broadcast pro data header and the page data header in the broadcast pro data is "0010".

As described above, the data unit parameter is included in the data unit of the broadcast pro management data (see Fig. 21) and the data unit of the page data (see Fig. 23). In order to be able to provide a programmable broadcast pro with a specific FM multicast, the parameter Pa (for example, 60h) representing the management data of the programmable broadcast pro as a data unit parameter, the parameter Pb (program representing the program of the programmable broadcast pro) For example, 61h) and a parameter Pc (for example, 62h) representing data (character, graphic data, etc.) are added.

This data unit data consists of a category code (sub broadcast pro code) and one or more segments following it. The type code is a code for subdividing the broadcast pro number (hereinafter referred to as "main broadcast pro number") (see Figs. 20 and 22) and is represented by two bytes (16 bits). In other words, the type code allows a plurality of sub-broadcast pro numbers to be set for one main broadcast pro number. Since the type code is displayed in 16 bits, it is possible to set a sub broadcast pro number of 0 to 65535 for each main broadcast pro number, which can greatly increase the number of broadcast pros.

Each segment consists of segment length, broadcast pro control number and parameters. The broadcast pro control information includes an operation mode, a program start date, a program end date, a program erasing date, and an advertisement data validity period. The operation mode includes a broadcast pro interworking mode, an accumulation mode, an information service mode, and the like, and their designations are designated by parameters in the segment.

The broadcast pro interworking mode is specified in data unit data for the broadcast pro interlocking program type broadcast pro. The accumulation mode is specified in the data unit data for the accumulation program type broadcast program. The information service mode is specified in data unit data for the information service broadcast pro.

However, each sending unit is sent out two or three times in succession without changing the update flag.

[5] description of data transmission of stored program broadcast program

Fig. 8 shows how data of a stored program broadcast program is transmitted.

The sending unit may be one module unit or a plurality of module units. It is assumed here that the sending unit is one module unit. However, broadcast pro management data is transmitted only at the beginning. Thus, the first one-unit transmission data includes one broadcast pro management data (including broadcast pro data header and data unit data), one page data (page data header and program unit corresponding to one module number and It includes a screen data unit). The second and subsequent sending units consist of one page data (including a page data header and a program unit and screen data unit corresponding to one module number).

In the case of transmitting the data of the accumulated program type broadcast program, the contents update flag (see Fig. 22) of the page data header is not updated even if the contents of the sending unit are changed. However, each sending unit is sent out two or three times in succession without changing the update flag.

However, each sending unit is sent out two or three times in succession without changing the update flag.

[7] Description of Editing Transmission Process by Specific Broadcast Program Configuration Transmission Control Unit 15 of Transmission System

FIG. 10 shows the editing delivery processing procedure of the specific broadcast program listing control section 15 of the delivery system shown in FIG.

Each time the next sending instruction is input by hand input or based on time (step 1), data for the next one sending unit is edited (step 2). Then, the edited delivery data for one sending unit is sent out two to three times in succession (step 3). When all data to be sent are sent (step 4), the process ends.

[8] description of broadcast pro data storing processing by CPU 50 of receiving system

Fig. 11 shows a broadcast profile data storing process once stored in the first RAM 53 of the reception apparatus 21 and performed on data determined as a broadcast program of a particular FM multicast by a service identification code. Fig. 11 shows a process for data (including new data) whose content update flag is updated.

First, one data unit (a data unit of broadcast pro management data or a data unit of page data) is taken out (step 11). It is determined whether the retrieved data unit is a data unit of broadcast pro management data (step 12). If the retrieved data unit is not the data unit of the broadcast pro management data, it is determined that the data could not be retrieved from the beginning of the broadcast program or from the beginning of the broadcast unit, and the content update flag is displayed in the data unit subsequent to the retrieved data unit. The same data unit is discarded (step 19). Then, the process returns to step 11.

If the data unit retrieved in step 11 is a data unit of broadcast pro management data, the content of the data unit of the extracted broadcast pro management data is checked (step 13), and the broadcast apparatus is controlled by the corresponding receiver (terminal 21). It is determined whether can be received (step 14). If it is determined by the receiving apparatus that the broadcast program cannot be received, the process proceeds to step 19, and among the data units subsequent to the extracted data unit, data units having the same content update flag are discarded. Then, the process returns to step 11.

When it is determined in step 14 that the broadcast program can be received by the reception apparatus 21, the contents of the data unit of the extracted broadcast program management data are stored in the second RAM 54 (step 15).

Then, it is determined whether or not there is a data unit (program data unit or screen data unit) of page data associated with the data unit of the retrieved broadcast pro management data (step 16). If a data unit of page data taken out exists, one data unit of page data is taken out (step 17). The contents of the data unit of the retrieved page data are then stored in the second RAM 54 (step 18).

In step 16, if the data unit of page data exists, the processes of steps 17 and 18 are repeated. In this way, data (including new data) whose content update flag is updated is stored in the second RAM 54.

If it is determined in step 16 that a data unit of page data does not exist, the flow returns to step 11.

Fig. 12 shows a broadcast program execution processing procedure performed by the CPU 50 of the reception system when a channel of a program broadcast program is designated by the user.

When a channel of the program type broadcast program is designated by the user, the program start date and the like are checked in the contents of the data unit of the program data stored in the second RAM 54 (step 21), and the program is executed. It is determined whether or not it is possible (step 22).

If it is determined that the broadcast program can be executed, it is determined whether or not the program command of the broadcast program is stored in the second RAM 54 (step 23). If the program command is stored, the command for one line is taken out (step 24). If the retrieved command is not an end command (step 25), the retrieved command is executed (step 26). Then, the process returns to step 23.

If it is determined in step 23 that the program command of the broadcast program is not stored in the second RAM 54, the program command of the broadcast program is waited for to be stored in the second RAM 54. If the program command of the broadcast program is stored in the second RAM 54 before the predetermined time has elapsed (NO in step 27, YES in step 23), the process proceeds to step 24 and a command for one row is taken out. If a command is not stored in the second RAM 54 even after a certain time has elapsed (YES in step 27), an error message is displayed on the display 31 (step 28), and the execution process of the broadcast program is ended. do.

In step 25, when it is determined that the command retrieved in step 23 is the end command, the execution process of the broadcast program ends.

The execution processing of the broadcast pro-associated program broadcast program will be described with reference to FIG.

First, when the start time of the broadcast program is reached, display of the broadcast program start is performed (step 31). The display of the broadcast program start is performed based on the program and screen data of module No. 1 already received and stored in the second RAM 54. In Fig. 13, a in [a, b] denotes a module number, and b denotes an item number.

In step 31, "Professional baseball quiz starts" of the screen data [1, 1] is displayed based on the DISP command on line 1001, and "wait for a while" on the screen data [1, 2] based on the DISP command on line 1001. Please ”is displayed.

Next, when the problem is reached, the program and screen data for asking the problem from the delivery system are sent out as page data of module number 2. When the page data of module number 2 is received, the following processing is performed based on the received data.

First, an effect sound is output (step 32). That is, based on the SOUND command on the line 1003, the effect sound "jaza-ang" is output for 1 second.

Thereafter, a problem is displayed and a response input wait state is entered (step 33). That is, based on the INPUTG command on line 1004, "child start, current turn at hit or home run" of the screen data [2, 1] is displayed, and "(1) hit (2) home run" of the screen data [2, 2] is displayed. After the message is displayed, you will be waiting for input.

Next, a confirmation display of the answer is performed (step 34). The processing in step 34 is executed based on the command of lines 1005 to 1011. If there is no answer input within the reply waiting time (countdown seconds) specified by the INPUTG command on line 1004, "no answer input" of the screen data [2, 3] is displayed based on the DISP command on line 1006. Then, the process proceeds to line 1012 of module number 3 based on the GOTO command on line 1007.

If the answer input is "1", the process proceeds to line 1008 based on the ONGCTO command on line 1005, and "hit" of the screen data [2, 4] is displayed on the basis of the DISP command on line 1008. Then, the process proceeds to line 1012 of module number 3 based on the GOTO command on line 1009.

If the answer input is "2", the process proceeds to line 1010 based on the ONGOTO command on line 1005, and "home run" of the screen data [2, 5] is displayed on the basis of the DISP command on line 1010. Based on the GOTO command at line 1011, the process proceeds to line 1012 of module number 3.

In the baseball being relayed, when the result of the above problem is returned, the program and screen data for printing the answer while displaying the correct answer in the delivery system are sent out as page data of module number 3. When the page data of module number 3 is received, the following processing is performed based on the received data.

First, the correct answer is displayed (step 35). That is, based on the DISP command in line 1012 of module number 3, "the correct answer was a home run" is displayed in the screen data [3, 1].

In addition, the user's answer is printed on the card 30 by a two-dimensional barcode (step 36). That is, after the argument field is defined by the FIELDB command on line 1013, the user's reply is printed on the card 30 by the PUTB command on line 1014.

Next, the user's answer is printed to the card 30 (step 37). That is, the argument position is specified based on the LLOCATE command on line 1015. Based on the VSET command on line 1016, the user's reply is converted into a character code. On the basis of the LPRINT command on line 1017, the user's reply is printed on the card 30 in character. The current broadcast program ends with the ENDC command on line 1018.

[11] explanation of interrupt display for other broadcasters

In a specific FM multicasting program, a commercial program consisting of a plurality of advertisement (CM) screens is transmitted in advance and stored in the second RAM 54 of the receiving system, and another broadcast program, for example, an information service broadcast program such as a weather forecast, is stored. It has a function of inserting and displaying a CM screen in a commercial program while displaying.

14 shows a commercial program received in advance and stored in the second RAM 54. In this example, the commercial program consists of CM screens 1 to N.

The interrupt designation of the CM screen is performed as follows in the broadcast program (hereinafter referred to as "main broadcast program") which wants to embed the CM screen of the commercial program during the broadcast program display. The data unit of the main broadcast program (the data unit of the page data whose data unit parameter is 62H) includes data unit data as shown in FIG. The data unit data also includes one or more segments. Each segment contains data for one screen.

When an advertisement screen is inserted after a display screen of the main broadcast program, as shown in Fig. 15, a CM interrupt command of, for example, "1F _HC " is placed at the head of the data for one screen corresponding to the display screen. (Other broadcast pro interrupt instructions) are inserted in advance on the transmission system side.

" _C " in the CM interrupt command "1F _HC " is a variable indicating the number of screens. The CM interrupt command "1F _HC " indicates to display the advertisement screen for the number of screens designated by " _C " after the corresponding one-screen data is displayed.

Thus, for example, when the CM interrupt command "1F _H 1" is included at the beginning of any screen data of the main broadcast pro, the screen is displayed by the CPU 50 and then displayed in the latest past in the CM broadcast pro. The next CM screen of the CM screen is displayed. That is, whenever the screen in which the CM interrupt instruction is included in the head of the screen data is displayed, the screen in the CM broadcast program is displayed to cycle in the CM broadcast program by the specified number of cycles.

In addition, data indicating the display valid period may be included in each screen in the CM broadcast program, and the display of the screen may be allowed only within the display valid period.

In the above embodiment, the case where the present invention is applied to FM multicasting has been described. However, the present invention can also be applied to data broadcasting other than FM multicasting (text broadcasting of television broadcasting, etc.).

According to the present invention, it is possible to provide a broadcast program executed by a program transmitted. According to the present invention, it is possible to provide a broadcast program executed by a transmitted program in multiple broadcasts. In addition, according to the present invention, it is possible to provide a broadcast program which is a broadcast program executed by a broadcasted program and at the same time, a broadcast program of contents related to the progress of the broadcast program of a broadcast other than the multicast program.
