Description

Analog broadcasting system and digital broadcasting receiver using digital information processing technology {A broadcasting system & broadcasting receiver for analog broadcasting service by data processing technology}

The present invention mainly relates to a technology to be used in an analog broadcasting system, and the recording, editing, transmitting, and receiving is performed by combining a remotely scattered information collector, an editing place, and a wireless transmitting station with a digital information network and performing airwave broadcasting over a wireless channel. It is a system configuration technology to make smooth.

In general, a large-scale analog broadcasting system that provides voice broadcasting to mobile users and fixed point users transmits the voice information produced at the performance station to the transmitting station through a dedicated line, and the transmitter of the transmitting station converts it to a predetermined radio frequency and transmits it to the air. It consists of a system.

The reason why the station should be separated from the station is that the station should be located in the downtown area where information is easily collected and edited, and the station should be installed in a location close to the service area in consideration of the radio communication range. It is true.

On the other hand, in order to select the installation site of the transmission station, consideration should be given to minimizing the reception area (Blanket Area) phenomenon caused by high power radio waves. Therefore, most transmission stations are limited to the mountainous areas or wide plains in the suburbs. .

As a means for electrically connecting the isolated performance station and the transmission station, a dedicated line is mainly used. A conventional broadcasting system for directly transmitting analog voice information to a transmission station requires a special high-quality analog dedicated line. This is a means to avoid noise, crosstalk, distortion, and loss inherent in the analog dedicated circuits that have a fatal effect on the broadcast, and to secure necessary bandwidth for transmitting broadcast information.

In order to secure the operation cost and the rapidity of the facility, some prior arts have attempted to replace the dedicated line with an RF (Radio Frequency) device, but the RF channel has a data transmission rate different from that of a microwave. In a broadcasting system which provides a late problem and also provides a radio wave service to an end user, frequency interference is likely to occur when the broadcasting information transmitted to the RF device is converted back into a radio broadcasting channel. It can not be applied, it can only be used as a facility in a factory area that allows the receiving end to output directly to the speaker or delivers alarm data with very low data volume at low power.

In addition, since the editing work for directly organizing the analog voice information requires editing the information created by the reporter one by one, it requires a high level of technical skill to connect the voice information and takes a long time. In other words, if one hour of audio information is edited by 10 reporters, the time required to play the recording is meaningless if the reporter is skilled. .

In addition, the conventional broadcasting system cannot eliminate the problem of directly collecting voice or sound as broadcast data even though the digital storage technology of MPEG Series is used, and thus, it is possible to directly use data obtained from various information sources such as the Internet. There is a problem that a human and material cost is required to produce broadcast information, and a delivery time of information is delayed because an experienced broadcasting expert such as an announcer must re-record by voice.

On the other hand, in terms of system configuration, while the communication technology enables channel control and the like, the broadcasting technology only performs broadcasting of a single channel. When the broadcasting system is applied to a multi-channel private broadcasting network, a transmission device must be installed for each channel. Since the broadcasting technology is less efficient than the communication technology, especially the receiving device applied to the communication technology has a superior ability to receive weak radio waves compared to the broadcasting receiver. Combining services provides the best of both worlds.

Information and communication technology has led to innovative changes in all fields, and as the field of use is expanding day by day, the development of technology and cost are continuing. As a result, broadcasting and communication should be converged. The necessity of researching new technologies to simplify the system and operation management, to save the network operation cost, and to simplify the editing technology is applied.

In view of this trend, the present invention provides a new broadcasting and telecommunications technology in which broadcasting and telecommunications technologies are fused. When this is advantageously used, it is possible to secure conditions for providing a broadcasting service with a single system of extremely small output and small scale. do.

The first object of the present invention is to transmit the broadcast information using a digital communication network to eliminate noise, etc. added from the communication network to enable high-quality broadcasting service even in a general-purpose communication line, and to transmit compressed information. It is to provide a technical means to increase the speed of distribution of broadcast information.

It is a second object of the present invention to provide a technical means by which a small number of personnel can easily edit the transmitted information.

A third object of the present invention is to provide a condition in which a private broadcast service can be expanded by increasing the efficiency of a broadcasting system to reduce operating costs and enabling various services.

A fourth object of the present invention is to provide an expanded means by which an edited broadcast file can be serviced through various communication functions so that broadcast information can be easily connected regardless of the connection between different types of systems.

To this end, the present invention is a coder / decoder (CODEC) or computer-controlled text-to-speech device that combines a plurality of reporters (or alarm devices) and a transmitting station and a performance station into a digital communication network and includes digital compression technology at the side end of the communication network. By connecting {TTI (Text To Speech) of CTI (Computer Telephony Integration) series, at least one reporter converts the raw information in voice or text form into voice or text digital signal and transmits it to a single performance. The performance station collects and edits the data and retransmits it to at least one transmitting station.The broadcasting station converts the received analogue signal into an original analog signal or converts text information into voice information and supplies it to the transmitter. To provide a comprehensive broadcasting system configuration means to collectively service.

In addition, the present invention transmits the raw information created by the reporter in the form of a packet with a label attached to the information created in the digital signal, and collects them in a performance studio to perform file-based editing based on the text marker. By doing so, it is possible to easily and quickly organize broadcast information in voice or text form only by checking the text markers without specifically checking the contents of the broadcast information. It provides a means for editing.

In addition, the present invention simplifies the transmission output reduction or configuration of the broadcasting system by controlling the transmitter of the transmission site manufactured by the communication technology with a given program and matching and matching the characteristics of the receiving device of the user so as to operate efficiently. It improves the efficiency of using the frequency and furthermore, enables the transmitter to be operated by the centralized remote control method and provides a highly efficient system configuration and operation means capable of fully automatic unmanned remote operation regardless of the installation place.

In addition, the present invention is to edit the broadcast file in an environment that can be provided to the server (ARS) server using the telephone network in the editing and can be efficiently serviced by the automatic response program upon user request Provide means.

Furthermore, the present invention broadcasts the edited broadcast file to the user in a digital packet communication method, and overcomes transmission error of the broadcast medium by converting the converted broadcast file into an analog signal or a text ⇒ voice in a user terminal device, and compresses the compressed information to the user. It provides a means for transmitting directly to the receiving terminal of the.

The scope of the present invention for this purpose includes a broadcast system and a terminal device that can use the service.

1 is a block diagram showing an embodiment of the present invention broadcasting system,

In order to convert text information and / or voice information input by a reporter to a data signal and transmit the data to a remote site, a keyboard for inputting text information, a microphone 1-1 for converting voice information into an electrical signal, and a microphone are connected. A first time division demodulator (1-2) which converts the analog signal output into a digital signal, completes it with a labeled information file, converts it into an information packet, and transmits it to a remote central processing unit (2); An information collecting device (1) of means for organically coupling a storage device (1-3) connected to the one time division demodulator and storing the information file;

In order to receive the data signal transmitted from the information collecting device 1, edit it artificially, and then retransmit it to the remote transmitting station 3 and the answering machine 4, the information packet is restored to the information file and the attached label is used. A computer device 2-1 for artificially editing the information file, converting the information file into a broadcast packet, converting it into a broadcast packet, transmitting it to the transmission station 3 and, if necessary, to the automatic response device 4; Voice information is collected and edited and / or organically combined with the second time division demodulator 2-2, which is connected to the computer device 2-1 for easy operation and reproduces the collected information file and the completed broadcast file. A central processing unit (2) of means configured to collect text information, edit text voice conversion, and transmit text information, or directly transmit text information;

In order to reproduce the broadcast file transmitted from the central processing unit 2 and transmit it to the broadcast medium, the received broadcast packet may be restored and reproduced as analog broadcast information, or the text information received as a broadcast file is converted into voice information and reproduced. A third time division demodulator (3-1), a transmitter (3-2) connected to the third time division demodulator (3D) and converting broadcast information reproduced in the form of voice or text according to the characteristics of a medium, and a third time division demodulator and transmitter A broadcast transmitting device (3) of means configured to combine a control unit (3-3) for controlling a transmitter under a set condition connected to the controller and informing a remote location of a broadcast result;

An automatic answering device incorporating an automatic answering program, including a text-to-speech technology, for voice service by reproducing broadcast information edited in response to a user's telephone 4-1 connected to a public telephone network (PSTN) ( 4);

The information collecting device 1, the central processing unit 2, the broadcast transmitting device 3, and the automatic answering device 4 are connected to the data communication network to form a comprehensive broadcasting system. ) Includes means for connecting a digital recording device for backup.

Reference numeral (2-3) is a microphone used to add voice information in the computer device (2-1), (2-4) and (3-4) is a speaker for monitoring broadcast information for convenience. (2-2, 2-3, 2-4) are collectively referred to as a second time division modulation unit.

The above configuration is representative of an example of performing analog radio broadcasting, but in order to easily understand the operation using the same, the following detailed operation description includes radio broadcasting directly collecting, transmitting, and transmitting text or voice information. As an example, a detailed operation will be described.

When the voice information is input as broadcast data, when the reporter (communicator) inputs the information into the microphone 1-1 by voice, the information is converted into a digital signal by the first time division demodulator 1-2, and then the storage device ( This process is the same as the conventional recording method, and the reporter knows that the voice information input by him is perfect enough to be used as broadcast information, and then the given input button (for example, ), And the file is created in the storage device 1-3 with the size corresponding to pressing the input button.

This is a function equivalent to digital recording. If the amount of information input is large (corresponding to the length of time that the voice information continues), the files are automatically generated at the appropriate time in the middle, but the means for creating or linking the files are implemented. Since it will be easily understood by those skilled in the information processing field without a detailed description, detailed description thereof will be omitted.

After completing the recording, the reporter creates a label for each file or bundles several files at a time. The information is added to the file in the form of a label, and an example thereof is shown in the following table.

In other words, in addition to the general file information automatically generated when the reporter inputs the voice information to create the information file, the reporter adds the information input by the reporter as a summary article to create a single information file that combines them as a whole. (Label) is for facilitating the editing operation in the central processing unit 2 of the performance studio described later.

In order to effectively use the label, it is advantageous that the summary article prepared by the reporter is recorded so that the contents of the voice information or the text information are implicitly displayed.

In this process, the reporter completes the information collected by the user as a file. The file completed by the above process is called an information file in the present invention. The same is true except that the character input by the keyboard is replaced.

If a reporter makes a mistake during the recording process, the reporter can select and delete or correct only the file during recording as well as after the information file is completed. In fact, the reporter is responsible for carrying out all editing work on the recordings in the area. If you want to check the already entered character information with rhyme, the automatic voice-to-character conversion (TTS) function to be described later to delete, modify or change the rhyme after the control code insertion process.

When the information file is created by the above process, the reporter designates the file to be transmitted and transmits it to the central processing unit 2-1. In this case, the first time division demodulator 1-2 uses the packet data as the packet data. It performs the data communication function to bundle and transmit to the central processing unit.

An example of a packet configuration using an X.25 data network in this process is as follows.

Since the information is transmitted to the data network such as X.25 and the receiving side restores it again to reproduce the original information file, the information communication technology is well known in the field of information and communication technology. Alternatively, when using an Asynchronous Transfer Mode (ATM) network, the packet structure is different, but since it is a professional and detailed information communication technology processed by a digital service unit (DSU) or a channel service unit (CSU), the present invention will explain the principle in detail. The detailed description is omitted since it is sufficient to do so.

The information file created by the reporter arrives at the central processing unit via such a data communication network. The time division demodulators 1-2, 2-1, and 3-1 of the process convert the analog voice signals into digital signals. In order to emphasize the principle of transmission by means of a flow control (window-control) or a storage device (1-3) for label input operation or data transmission processed in the first time division demodulator (1-2). In view of its function, the physical structure of the first time division demodulator 1-2 is actually regarded as a single card attached to a computer (desktop computer or note-book), and as a whole, an overall computer. It can be considered a function.

Accordingly, the first time division demodulator 1-2 includes a means for the reporter to input raw information in the form of a character to create a broadcast file, and the broadcast information created in the character information is described later by the central processing unit and / or Speech conversion is automatically performed by computer-processed text to speech (TTS) inherent in the broadcast transmitting device and / or the answering machine.

Compared to the conventional technology, the process of collecting information files into the central processing unit compares the signal transmission from the local (Sokcho) to the central (Seoul), for example, even in the conventional analog transmission technology. Crosstalk, loss, noise, distortion, etc. occur on a dedicated line of the process, but the present invention transmits digital information, so there is a possibility that unexpected noise is inserted in the middle unless noise is imposed on the microphone 1-1 of the input process. There is no excellent advantage

In addition, since digital information can be easily compressed, the transmission can be completed within a much shorter period of time than the real-time voice transmission speed, depending on the transmission band of the digital communication network. It is very effective.

It is understood that the transmission speed characteristics faster than the real-time voice transmission speed can be used not only for recording broadcasting but also for live broadcasting that delivers information in real time.

Next, when the central processing unit collects the information files transmitted by the plurality of reporters in the same manner as described above, the editing operation must be performed. This is because the order of the information is entangled.

In other words, the information file sent by a reporter in one province (Sokcho area) includes sea weather, departure / arrival vessels, and market conditions, and the same information file sent by a reporter in another province (Incheon area) is the same. When composed of broadcast files, users receive unorganized information that is cluttered by type.

Therefore, the information to be actually broadcast must be reconstructed by type by going through the process of editing once again, and at this time, there was a problem that it takes a long time because the information files of all reporters must be edited by entering them one by one. Connecting voices to each other also has a cumbersome problem because you have to work with editing the tape or watching panoramic computer graphics.

In contrast, the present invention simply checks the label (summary article) added as text information without having to play the information file, and collects the files transmitted from various places in one place and drags or sorts them to simply edit them by type. The ease of editing can be understood without having to explain it for a long time.

In order to effectively utilize the present invention, the reporter broadcasts "Sea Meteorological Information from Incheon", "Information from Incheon Local Area", "Industrial Market Price in Incheon" before inputting voice information for each file. It is effective to enter the information on the start, and then, in the central processing unit installed in the performance, for example, "I'll tell you the weather of the sea collected by the reporters of the whole country," by voice or text, you can add more information about the sea weather as a whole. If you edited to link only the information file, the completed broadcasting file is "We will tell you the weather of the sea collected by the reporters of the nation, the sea weather to inform you in Incheon ........., the sea weather to inform you from Gunsan Is ........., is the sea weather in Mokpo ........, in Tongyeong ........, in Busan ...... " car It is easy to see that they are listed as examples.

In such an editing process, not only the broadcast files transmitted to all transmitting stations can be the same, but each editing station has a different editing structure, that is, the first transmitting station {site (1)} starts from the weather broadcasting and the n transmitting station {site ( n)} can produce a broadcasting file to start from the market situation broadcasting, and in all the editing work to group information by type, region, or time difference, the information transmitted by a plurality of reporters, such as market information or local weather, is listed. By applying the concept, editing can be done by checking only the written summary article, which brings convenience and speed to the work.

The label added to the information file only displays the text information for easy editing, but the label is removed when the file is restored and played back as pure voice information. However, the label uses the text-to-speech (TTS) technology. It can be used directly as guide information.

On the other hand, when a reporter produces an information file with text information and transmits it, the editing work is made by checking the label, selecting the information file, and then combining the text files into a single file. In this way, the broadcast file produced by the character information is automatically converted into voice in a central processing unit to be described later and collectively combined with the voice file, or automatically converted into text ⇒ voice by the broadcast transmitting device and transmitted.

Using the principles of the present invention it can be configured to perform another action. For example, the information acquisition device 1 is configured to transmit a digital on-off signal as an early warning (a kind of sensor function), and this signal is supplied. In this case, it is possible to automatically create a broadcasting file by searching and combining the information file previously stored in the computer device 2-1 of the central processing unit 2, and in this case, it is a technology that can be used for early warning such as civil defense alarm system. .

In this case, however, the voice produced by the reporter (or administrator) is directly stored in the computer device 2-1 by using the second time division demodulator 2-2, but the information file is also treated as a file unit. It will therefore be appreciated that the principles of the present invention are used.

In this way, the reconstructed file after the information file is reconfigured and edited is called a broadcast file in the present invention.

In addition to transmitting the broadcast file, the central processing unit (2-1) generates a control file for remote control of the transmitter and transmits the information to the transmitting station. This is automatically performed when the control station sets the remote control command to control the transmitter. This is a file generated and transmitted in a specific manner, and specific information is information on remote control such as power on-off, output adjustment, transmission frequency setting, transmission channel program setting by time, and the like.

In this way, the broadcast file and control file edited in the central processing unit (2-1) are stored as a history in the backup digital recording device, and transmitted to a remote transmitting station for broadcast service. Not only means for transmitting the broadcast file to the transmitting station but also means for transmitting to the answering machine 4 is included.

The backup recording device performs digital recording in the same way. By adding a storage compression technology that removes the silent part of the voice, it is possible to compress and store broadcast contents of at least 200 hours on a single CD (640 MByte Compact Disk). Will be.

There are two methods of transmitting from the central processing unit to the transmitting station. One of them is the general method of directly transmitting the monitor output from the central processing unit to an analog dedicated line or a general telephone network. How to send.

Collecting information through a general analog transmission line or transmitting it to a transmitting station is well known in the art in principle, so a detailed description thereof has been omitted, and the following description of the present invention corresponds to the transmission of the information to a digital network.

The transmission to the answering machine 4 mainly utilizes a local area network (LAN), and the transmission of the broadcast file to the remote transmission station 3 is also performed by data communication in the reverse process as when the information file is collected. Since the communication between the computer device 2-2 and the third time division demodulator 3-1 is performed to automatically store the transmitted and transmitted data, a redundant description of the packet structure will be omitted.

However, the automatic answering device may incorporate a separate additional text-to-speech (TTS) technology in order to convert the text information directly to the voice information after receiving the text information.

The control unit 3-3 installed at the transmitting station and controlling the transmitting device 3-2 automatically changes the channel frequency at a set time or operates the transmitter by a control file transmitted from the remote central processing unit 2-1. Control device, and as a result is a device configured for the purpose of informing the remote of the operating status of the transmitter,

The main role of the control unit 3-3 connected to the third time division demodulator and the transmitter is to control the transmitter as well as perform the control and remote monitoring of the transmitter by a remote control command via the third time division demodulator.

Therefore, the controller 3-3 of the present invention can implement or selectively implement all three functions, namely, its own transmitter control, remote control, and remote monitoring data transmission function. Controlling the transmitter on condition means implementing one or all of these three functions.

Information notified to the central processing unit 2-1 by the control unit 3-3 is a history (History) and a monitoring signal (Telemetering signal), etc., for each channel. All information related to file reproduction is included, and these remote control and remote monitoring information are connected by communication between the control unit 3-3 and the computer device 2-1 via the third time division demodulator 3-1. do.

Accordingly, the transmission station of the present invention does not need to reside in person, that is, it has a condition that can be operated unattended, and can be managed by a method of remotely controlling and monitoring all the transmission stations 3 in one central processing unit 2. Done.

The broadcast file transmitted from the central processing unit is reproduced as raw voice information created by the first reporter in the third time division demodulator (3-1), and this audio information is sequentially supplied to the transmitter according to the scenario commanded by the central processing unit and broadcast information. The control unit 3-3 or the third time division demodulator 3-1 performs the function of adjusting the time difference between the voice information supplied to the transmitter and the operating conditions of the transmitter.

On the other hand, if the broadcast file transmitted from the central processing unit (2) is text information, the third time division demodulator (3-1) and the automatic response device (4) converts it into voice information. Transformation (TTS) technology.

Text-to-speech technology is a software technology belonging to the category of CTI (Computer Telephony Integration) technology that manages and controls a telephone facility with a computer function. The scope of the present invention applies to converting a broadcast file to play back voice information or to an external DB ( It is used to convert the broadcasting file stored in DataBase) into voice information by automatically searching for the program under the given condition. When it is expressed correctly, it is TTSC (Text To Speech Conversion).

In fact, when the text information is converted to the voice information using the text-to-speech technology, the strength or lowness of the voice may be somewhat unnatural compared to the human voice, but it is possible to operate a broadcasting station without an announcer, that is, a studio and a plurality of reporters. There is an effect that can overcome the individual differences (diagrams, etc.) included in, it is a technique that is particularly recommended in the use of the present invention because it can utilize the feature that can be freely selected for the conversion function to the tone of the sexes.

Furthermore, rather than converting the voice information to digital and transmitting the text information as it is, the text information conversion is greatly reduced since it has a natural information compression effect that greatly reduces the amount of data transmitted between the reporter device, the central processing unit, and the broadcast transmitting device. It will be appreciated that applying the technique to the present invention is the most preferred method.

The text information may be automatically converted to text information (voice recognition function) when the reporter's voice is input to the microphone. In this case, the reporter's voice is converted into a computer speech in the form of a standard word, and in particular, a tone is changed. As a result, the characteristic effect is retained.

The first and second time division demodulators (CODECs) 1-2 and 3-1 shown in the present invention are actually configured to have a second time division demodulator 2-2 connected to the computer device 2-1. The same as the above, the detailed operation of converting and transmitting voice information into a digital signal will be described in more detail as follows.

The first time division demodulator (1-2) digitizes an analog audio signal by using a function of a digital signal processor (DSP) and compresses it again to generate an output (computer output). In the time division demodulator 2-1 or the third time division demodulator 3-1, the original analog signal is reproduced by decompressing in a reverse process of the same algorithm as that of the first time division demodulator 1-2.

As an example for digitizing an analog voice signal, a quantization process is performed at a predetermined sampling frequency, which is a technique known in the ICT based on the Nyquist theory.

Since the description of the present invention specifically discusses the quantization technique, it is a separate field, and therefore, the digital transmission technique will be described to the extent that the transmission technique of the present invention can be understood.

In order to satisfy the condition of Sampling Frequency≥Maximum Voice Frequency × 2 based on the Nyquist theory, Sampling Frequency is set to 8KHz in the telephone network using 3.4KHz. = 64 Kbit '.

This 64Kbps signal is the basic channel bandwidth using a general Pulse Code Modulation (PCM) telephone network, but the DSP of the present invention uses a known voice compression algorithm such as G.723 to compress it back to 1/30 to generate a file for transmission. This will greatly increase the speed or improve the storage capacity of the backup recording device.

Standard compression techniques such as G.723 are also possible with other compression techniques in the overall concept, such as the Moving Picture Expert Group (MPEG) or Joint Photographic Coding Expert Group (JPEG) standards, but 1/30 compressed information by G.723. Suppose that the system transmits 120 minutes of voice information based on 64Kbps. It is easy to see that since the transmission is completed for 2 minutes, the original reporter can simply transmit the original audio information stored for 120 minutes in 2 minutes.

Even if no compression technique is applied, the transmission band is twice as fast when using 128 Kbps, four times faster when using 256 Kbps, and about 30 times faster when using E1 (2.048 Mbps). Understand the principle of faster transmission speeds.

In practice, the remote data transmission of the present invention is also preferably using the Internet network of the TCP / IP protocol, even when using the cheapest Asymmetric Digital Subscriber Line (ADSL) can be operated at a transmission speed of 1Mbps or more.

Conventionally, in transmitting an analog signal, a dedicated line having a special bandwidth (10 KHz or more) capable of transmitting a bandwidth of 6 KHz (radio broadcast signal) without distortion is required, but according to the present invention, since the sampling frequency is increased, the transmission speed is somewhat increased. There is only a dropping effect, and there is an advantage in that the quality of the voice signal is not degraded even when transmitted in a general analog-class dedicated line (3.4KHz).

Of course, when the transmission speed is increased, a buffer for temporarily storing information is essential to overcome the speed difference, but a computer or communication included in the time division demodulators 1-2, 2-1, and 3-1. This can be handled by the server's memory allocation, so there is no problem at all.

Compared with the conventional technology of transmitting voice or text information between a performance station and a transmission station as a digital signal, the present invention eliminates noise, crosstalk and distortion as well as the compression and storage effects as well as the characteristics of digital communication. Therefore, it is possible to maintain the high quality of the voice, so that using this eliminates the need for a special high-quality dedicated line dedicated to broadcasting, which must be considered in the prior art.

Accordingly, in the related art, a performance station and a transmitting station can be constructed only within a limited distance where a high-quality analog dedicated line can be constructed. However, according to the present invention, the distance can be expanded indefinitely, so that a single broadcasting network can be constructed nationwide and even an overseas installation can be performed. It also has the advantage of being able to operate as a single comprehensive broadcast program including log stations.

In one embodiment of the present invention, the broadcasting medium finally delivered to the user is mainly composed of SSB (Single Side Band) radio frequency within 2 MHz to 27 MHz band, which is a high sensitivity receiver configuration technology used for long-distance communication. It is to apply to.

In general, SSB communication method can obtain good reception condition of S / N 20dB or more even at electric field strength 0dB / m (1) / m), so that general radio receiver should be more than 40dB / m (100㎶ / m). There is a very good advantage compared to obtaining the reception state, which means that the same service is possible even if the transmission power of the broadcast transmission apparatus is reduced to 1/10.

The reception device for this purpose is to receive a broadcast service by simply adding a frequency to the SSB transmission and reception device used for conventional communication, which is shown in FIG. 2 from the broadcast transmission device (Site " 1 ") of FIG. The path transmitted to the mobile station "Mobile" 1 corresponds to this, and the means for receiving the present invention by extending the radio frequency in the present invention is expressed as "to be received in accordance with the broadcast medium". .

In order to extend the functions of the communication device, the broadcast transmitting device and the receiving device 5 may be implemented in other configurations such as the broadcast transmitting device (Site "2") and the mobile station (Mobile "2") of FIG. When the third time division demodulator (3-1) connected to the transmitter is moved to the output terminal of the user terminal (5), and the digital modulator (MODEM, 3-5) is installed in place, the transmitter outputs it. The demodulated digital signal is sequentially demodulated from the terminal device, which is a user receiving device, to the digital demodulation device (MODEM, 3-5) and the third time division demodulator (3-1), so that the same analog signal is reproduced. In particular, when the user terminal device is manufactured for data communication, it is a very advantageous method of receiving analog and data in one terminal device.

Such digital transmission can be a very powerful means because it can overcome the noise or transmission error generated during the transmission in the wireless channel and also implement the multimedia service with a limited number of channels.

At this time, if the text-to-speech conversion technology is applied to the third time division demodulator (3-1), the broadcasting file transmitted from the central processing unit to the text information is also automatically converted into a voice signal, and the text information is transmitted to the user terminal device. It may be transmitted as it is to be automatically converted to a voice signal, the multimedia information is implemented by adding a text playback or voice playback command code to the text information transmitted to the terminal device.

If the user terminal device implements the text-to-speech technology, it can be seen that the text information transmitted as broadcast information can be received and stored and reproduced in sequence, thereby greatly improving the efficiency of the wireless channel due to the compressed information transmission effect.

On the other hand, the broadcast file transmitted from the central processing unit (2) to the answering machine (4) in response to the user's request when the user 4-1 is connected to the answering machine over the public telephone network (PSTN) It plays a function of reproducing and serving it as an analog voice signal, and this general operation makes it possible to know that the voice information or text information once edited in the central processing unit is variously used as CODEC or CTI technology.

The technique of retrieving the corresponding information file according to the user 4-1 request from the automatic answering device 4 is a kind of the automatic answering device (ARS) technology that is widely known and widely used in this field. Or replace with the above-described principle conceptual to search for information stored in the text and convert it to speech.

However, the automatic answering device can search and provide text information of any database using text-to-speech technology, so it can be linked with an external database (not shown), for example, a statistical database or a wireless data mail server. Textual e-mail information can be converted into voice and provided.

3 and 4 are hierarchical structure diagrams and flowcharts showing a broadcast system configuration method and an operation method of the present invention. The system configuration method and the operation method of the present invention will now be described using FIG. 3 and FIG. It will be described in detail.

The present invention consists of seven layers, each of which is an initialization step (L6), source file generation step (L5), information file creation step (L4), information packet transmission step (L3), broadcast file editing step (L2), the broadcast packet transmission step (L1) and the broadcast transmission step (L0), respectively.

Hereinafter, each layer will be described as follows.

① When power is applied, each device in the system performs the initialization step. (101)

This process, like all electronic devices, is the process of clearing an uncertain output and waiting for a user command or an operation command for a given condition.

However, the present invention includes a means for clearing the device for each device when the power source is individually operated or the operating conditions are reset individually due to the characteristics of the devices scattered at different locations.

② When the reporter inputs the raw information, the broadcast collecting device performs the source file generation step of automatically generating the source file according to the given condition. (102)

In this process, the voice information file is continuously generated until the reporter inputs or generates a voice information file by a given condition, that is, a minute unit, and the size of the file is continuously adjusted according to the condition or reporter operation given in advance. It depends on the time it is written.

If the reporter wants to modify the voice recording, the user can open the file and modify it or delete the file and record it again.When editing the file, play the recorded information and stop at the place where you want to modify it. You can modify it again, and if you type it as a character, you can do the same.

However, if you want to complete the character information into an information file, you can check the rhyme with the character-to-speech function in advance.

The created file is a process of converting an analog signal into a digital signal and then compressing the generated signal and generating it as broadcast character information directly input by a reporter. The function necessary in this process is called a source file generation function and a file content correction function in the present invention.

On the other hand, in this process, the drive signal is generated on-off in case of early warning. In this case, there is no recorded content, but the information file is generated as "on signal" information that can transmit an alarm.

However, when the information file is generated only by the "on signal", it will be known in advance that the signal is combined with the file searched by the central processing unit of the step described later to be made into a broadcast file.

③ After generating the source file, the reporter performs the information file creation step to add a label to the created source file. (103, 104, 105)

This process adds additional character information to a file recorded as voice information or a file input as broadcast character information so that the user can check what is the content with only the added character information without playing the file by voice. In the process of adding a separate label, or label, to recognize the information file, the reporter or editor clicks on the file, selects the summary article described above, and implies the contents of the source file. Character information is recorded.

Even if the article contents are recorded without the summarization by text recognition by the computer's voice recognition function, there is an advantage that can be compared with the playback of the voice because it can be quickly confirmed in the form of speed reading in the later editing process.

Therefore, this information file creation step includes all means for the reporter (user) inputting the label as separate text information, as well as optional configuration means configured to automatically create a label with text by the computer's voice recognition function. The function for this is called an information file creation function in the present invention.

When the "on signal" of the early warning is transmitted, this label preparation step is performed or omitted in the central processing unit described later.

④ When label creation is completed, the reporter performs the information packet transmission step of selecting the created information file and sending it to the central processing unit as a batch of information packets. (106, 107)

This process is a process that is automatically transferred when selecting a file to transfer from among several created information files and specifying a destination. The selected information file is treated as an information packet sent by one reporter and is processed as a destination through a data network. The device is reached and automatically restored to an information file.

When the information file is to be transmitted, of course, another compression technique may be additionally applied to include a means for compressing the character information included in the source file.

At this time, the transmitted data can be transformed into a packet structure suitable for data communication network again. In case of X.25 data network, it is subdivided into 255 byte units. In case of Frame Relay, the packet data is controlled by variable length from 4,000 byte to 8,000 byte. Will be reconstructed.

However, in the present invention, the information packet is composed by combining files means "significant packet data" composed of information file units, and the packet data is composed of 255 bytes or 8,000 bytes during data transmission. It is different from "significant packet data" that does not need to be known.

The packet data transmitted through the data network is not sequentially flowed through a single circuit like a telephone network, but is transmitted through various unspecified paths as a path through a routing table of the packet network. The header is used to restore the final information file in the same order as the originally transmitted packet structure and to supply it to the central processing unit.

In the present invention, the transfer execution function required for this process is referred to as an information packet transfer function and an information file restore function. However, except for the communication network transfer functions such as path control, flow control, or error control used in the data network, the terminal side computer apparatus is used. Since it refers to a series of processes to be processed in, the data network is regarded as the same idea even if it is replaced by a general telephone network (PSTN) using a modem as well as the Internet network.

In this process, if the transmitting station and the central processing unit are in close proximity, the information packet transmission function is a term that includes all of these means, since it may be transmitted directly to a local area network (LAN) without requiring a data network.

In this process, the "on signal" of the early warning is transmitted as simple trigger information without a label, and the handling process is the same.

⑤ Using a plurality of information files reached from the information packet transmission step, the editor performs a broadcast file editing step of artificially editing them. (108, 109, 110, 111, 112, 113, 114)

This process refers to producing a broadcast file by completing a broadcast file by sorting a plurality of information files transmitted by various reporters in various regions or information files obtained from a medium such as the Internet, or by ordering the time difference. In order to connect information files between regions, a means of additionally adding voice information or text information or modifying the contents of the information file to add or delete recording or text is also included.

However, the label added in the previous step is not used as the contents of the information file except for special cases, and is used only as information for editing. The same applies even when the label is added again after the editing is completed.

In the editing process, various broadcasting programs can be composed. The broadcasting file required by the first transmission station connects the information files in the order of turning left along the national coast, and the broadcasting file required by the second transmission station makes the information file in the order of turning right along the national coast. In addition, weather, current affairs, and market conditions can be configured in a different order, which is advantageous from the point of view of the recipient to prevent boredom with the same broadcast program for each channel.

However, even when editing as described above, since the sequential sorting is performed by using the reporter's unique number and label, the time required for it can be drastically reduced, and thus, it can be seen that an effect not seen in the prior art can be obtained from the present invention. There will be.

This process naturally includes a means of making a small broadcast file suitable for an answering machine or re-editing the collected information file with only a header so that the answering program can be executed in the answering machine.

In this process, a control function that enables all editing on a file basis is called a broadcast file editing function in the present invention. It consists of a file playback function and a monitor function for reconstructing the completed broadcast file itself, including label correction function and text-to-speech technology, and reconstructing the broadcast file after voice conversion.

However, the file content editing function and label correction function are similar to or extended from the functions of the source file creation step and the information file creation step.

On the other hand, in order to handle the "on signal" of the early warning in this process, the central processing unit (2) has to make an information file for alarm broadcasting in advance, where the microphone (2-3) and the second time division demodulator (2) This is performed by the computer device 2-1 using the function of converting the text information into the text-to-speech technology using the -2), and when the "on signal" is supplied in the previous step, the computer device (2- In 1), the stored alarm broadcasting information file is searched and the broadcasting file is automatically edited and transmitted.

In this case, it is natural that the process of creating or editing a label can be omitted. This is because the computer device automatically edits the broadcast file editing function.

⑥ When the editing is completed, the broadcast packet transmission step of transmitting the broadcast file to the corresponding broadcast transmitting device including the completed broadcast file and a control file configured as necessary is performed. (115, 116, 117)

This process is the process of reaching the broadcast file to the corresponding transmitting station and the answering machine by sending the edited broadcast file with the addition of the destination, and also constructing the broadcast packet based on the principle that the information packet is reached and transmitting / reaching it. It will restore the broadcast file.

In this case, the information file transmitted may include not only a broadcast file in which an information file is created by voice information in the central processing unit, but also a broadcast file in which an information file is created by text information.

In this process, transmitting different broadcast packets to the first transmission station and the second transmission station or storing them in a backup recording device is also the same as described above, and the broadcast packets or information files transmitted to the answering machine are also located at a short distance through the computer network. Including the means for transmitting is as described above.

As such, when the broadcast packet is transmitted, remote control information (control file) for controlling the transmitter may be included. This is the case when the transmission station is operated as an unmanned operation or an automated facility.

The remote control information included here can organize the scenario including not only the control function described above, but also control information such as a broadcast start command and channel change, and also information for controlling the general control and broadcast output of the transmitter. The function enables broadcasting while automatically switching channels with a small number of transmitters.

The control function required for this process is called a broadcast packet transmission function and a broadcast file restoration function in the present invention.

⑦ The broadcast file reached to the broadcasting transmitter is interpreted as the information provided by the reporter and reproduced as voice information and supplied to the transmitter, or the broadcast file itself is supplied to the input terminal of the transmitter, and the control file is processed as information for controlling and monitoring the transmitter. And finally performs a broadcast transmission step of broadcasting to a service target. (118, 119, 120, 121, 122, 123, 124, 125).

In this process, the transmitted broadcast file is played and finally supplied to the transmitter as an analog signal, and the simultaneous control file is analyzed to control the transmitter with an appropriate command. The third time division demodulator performs a function of controlling the operation of the broadcast signal and the transmitting apparatus until the third time division demodulator is linked to each other and stabilized under the changed setting condition.

Therefore, this process is a final step of performing broadcasting as the above series process, and the third time division demodulator operates as a time division demodulator (CODEC) or text-to-speech (TTS) function to wirelessly broadcast broadcast information reproduced as an analog signal. It is converted into frequency and supplied to the antenna, or the broadcast file itself is converted into radio frequency and supplied to the antenna to propagate to the public.

However, when the broadcast file itself is input to the transmitter and reproduced as a voice signal by the user receiving apparatus, the third time division demodulator 3-1 is connected to the user terminal apparatus or the receiving apparatus and the input terminal of the transmitter 3-2 and the user. Since the modem (MODEM, 3-5) should be connected to the output terminal of the receiving device, an example of the embodiment is shown as Mobile " 2 "

In FIG. 2, the modem 3-5 converts the digital information transmitted from the central processing unit 2 into an analog signal that can be handled by the transmitter, and the modem 3-5 of the receiving apparatus transmits it again. The digital signal is converted into a digital signal and supplied to the third time division demodulator 3-1.

However, even when analog signals of the same category are output from the third time division demodulator 3-1, the analog signals handled by the modems 3-5 are analog voice information or text information that are handled by the modem 3-5. This is different.

The control functions required for this process include the broadcast file playback function and the broadcast control function to control the operation of the transmitter and the broadcast file play function to modulate and amplify the analog signal (digital modulated signal or audio signal) to the radio frequency. Broadcast file playback function in time division demodulation process.

If the digital broadcasting is performed, the broadcasting transmission function is performed first, and then the broadcasting file reproduction function is performed.

In detail, the remote control monitoring function includes a time control function for controlling the operation time of a transmitter, a channel control function for controlling a channel of the transmitter, and a remote control function for informing a response signal for remote control and remote monitoring accordingly. do.

This process also includes a device control function that allows the transmitter to inspect itself or control it artificially.

The above embodiment of the present invention is not limited to the above embodiment because only one embodiment for describing the technical idea of the present invention out of various means for implementing the present invention to the last.

The label of the present invention may be replaced by an image or a video as well as a text, or may be additionally added thereto. Also, by connecting a speaker to an output terminal of a transmitter and implementing a broadcast transmission function using a simple amplifier function, the label may be used as a private broadcast in a limited area. It can also be used as a voice broadcasting function of the nationwide civil air alarm system,

Even when the broadcast file of the present invention is intended to be implemented as a TV video broadcast using an ATM communication network, it can be easily implemented by applying from an exemplary embodiment of the present invention, but it can be understood by those skilled in the art. The description is omitted.

Assuming that the transmission station of the present invention as an in-house broadcasting facility, it can be seen that the broadcasting file can be directly played by the central processing apparatus and used directly as in-house broadcasting without having to transmit the broadcasting file using a data network.

The third time division demodulator (3-1) of the present invention may additionally connect a separate automatic answering device (4) to perform an outgoing / incoming service of a text-to-speech (TTS) function. The demodulator 3-1 may implement a bidirectional transmission function by configuring to function as a voice / character input (including voice conversion) function of the first time division demodulator 1-2 used by the reporter.

In addition, the central processing unit may additionally apply a function of receiving a public broadcast such as a radio or collecting and editing data from another service provider by connecting a separate radio receiver, a telephone or an internet network, and using various display devices. Although it may be applied, this can be easily carried out from the present invention of the above various means, and thus detailed description thereof is omitted.

In this case, however, the broadcast collecting device is physically integrated into the central processing unit and performs its function as a software program.

In this case, the broadcast collecting device and the text-to-speech technology are physically included in the central processing unit or separately included computer means. In this case, the reporter is actually an editor who manipulates the central processing unit. Is identified with

Therefore, in the present invention, the reporter and the editor are classified by the role of each operation stage, not by the distribution of personnel.

In the present invention, the reporter inputting the original information includes a meaning that the reporter inputs a text, voice, image, or video. When the receiver is used for receiving data, the video or image / text / audio may be simultaneously provided. The term "converting text to speech" includes converting a sign or number into speech.

As can be seen from the above description, according to the present invention,

Since the broadcasting information is transmitted using the digital communication network, it completely eliminates the noise added from the communication network and also greatly reduces the transmission time by transmitting the compressed information.

At least one distributed reporter creates basic data by directly writing and editing unit broadcasting programs by voice or text, and allows the central processing unit to edit them comprehensively so that free broadcasting information can be organized only by computer control. As a result, it is possible to obtain a broadcasting station without a special broadcasting professional such as an announcer and a studio.

In addition, according to the present invention, since the transmitting station that transmits radio waves in fact plays a role of a small output relay device as compared to the conventional radio broadcasting transmitting station, the conventional local broadcasting system construction conditions are not limited to the installation place. The broadcasting network can be operated as a single program, and even in this case, automatic system operation and remote control monitoring can be performed, thereby increasing the reliability of the facility operation and simultaneously operating multiple transmission stations in a centralized manner. There is an effect that can implement a high-efficiency broadcasting system capable of viability.

In addition, according to the present invention, by greatly utilizing the function of the receiving device manufactured by the communication technology, the output of the broadcasting transmitting device is greatly reduced, thereby minimizing the size of the broadcasting facility and improving the efficiency of using the valuable radio resource, the frequency. Broadcasting technology and communication technology can be used for broadcasting service and automatic response service by using the storage capacity of the device and the automatic conversion of text to speech. By integrating this, synergies can be achieved with extremely streamlined operations and easy service expansion.

In addition, the present invention can construct an integrated early warning system that collects the operation signal from the early warning scattered with only a small amount of data and informs a plurality of users through digital signal processing technology and wireless relay. It is an advantageous invention that can be used as a public service alarm broadcasting to reduce the number of operating personnel.
