Description

Digital music broadcasting method and terminal used for the same

The present invention relates to a digital music broadcasting terminal. More particularly, the present invention relates to a music broadcasting terminal which downloads digital music files from a server and stores them in predetermined categories, and extracts music files one by one from a category selected by a user and continuously plays them. .

In places where music is always played, such as cafes, cafes, restaurants, other offices, hospitals, and public places, it is difficult to use radio broadcasts such as FM and AM as sound sources. This is because most radio broadcasts must have a comment, and even if there are no music announcements, it is not possible to selectively listen to music of the desired genre or theme due to the public nature of the media.

In the past, music broadcasting was also performed by cable. However, wired music broadcasting has not received much response from consumers due to the high cost of installing and operating wired networks and the difficulty in running themes that consumers want, and the rapid spread of cable TV and the Internet. Affected by the decline.

On the other hand, an automatic music performance cycle has been developed in the past, and nowadays, a so-called MP3 player is widely used, in which an individual directly downloads and stores multimedia files such as MP3 from a web server using the Internet. This is a technology for reproducing music by directly executing a file containing music, unlike a conventional tape or CD, and a user may selectively select and download desired music and store a dozen songs on a single CD.

However, the automatic juke box is a CD or LP that can store about 15 songs per piece, and the number of music that can be embedded in a limited size is limited, and the mechanical medium As an exchange method, the music stops flowing, and there is a problem in that the update cost for the new song is slow and slow.

In addition, since the MP3 player can store 5 or 6 songs when the music storage medium uses about 16MB of memory card, the storage medium is so small that the MP3 player is not suitable for music broadcasting that needs to play other music for a long time.

An automatic juke box is a CD or LP that can only hold about 15 songs per piece, and has a limited number of songs that can be embedded in a limited size. As a result, the music stops flowing, and there is a problem in that the update cost for the new song is slow. In addition, since the MP3 player can store 5 or 6 songs when the music storage medium uses about 16MB of memory card, the storage medium is so small that it is not suitable for music broadcasting that requires long time to play other music.

Accordingly, the Applicant has developed a new type of digital music broadcasting terminal by combining the concept of wired music broadcasting with the concept of digital music files.

After downloading various music files through the Internet, these files are classified into certain categories and stored, and when a user selects a category, the music file stored in the corresponding category is extracted and played.

The music file used in the present invention includes a parameter so that a user can select and play music that fits perfectly according to season, day of the week, weather, etc., even if the user does not select it.

In addition, since the present invention should play a role of broadcasting only music at all times, even if each independent music file is downloaded from the server, when the terminal plays the file, the file is processed so that the connection between the first and second songs becomes smooth. It is necessary. You should be able to download new or additional songs from the server from time to time (or regularly).

Accordingly, an object of the present invention is to download and download various music files through the Internet and store these files in a certain category, and when a user selects a certain category, the music files stored in the corresponding category are extracted and played and played. The present invention provides a digital music broadcasting method for fading out / in processing a space therebetween and a terminal used therein.

Summary of the invention

In the present invention, a music broadcasting web server (hereinafter referred to as "server") and a music broadcasting terminal (hereinafter referred to as "terminal") are made in a system that communicates via the Internet. The server produces a music file (hereinafter referred to as "file"). In this case, the identifiers are produced by including a predetermined classification scheme. The terminal downloads the file from the terminal and stores the file. When the user selects a classification, the terminal extracts and plays a file belonging to the classification from the stored files.

The file playback process in the terminal includes: i) extracting the first song, decompressing, playing the file, fade-out the end, and ii) playing the second song during playback of the first song. Extracting, decompressing the second song, fade-in the introduction of the second song, and repeating the ending of the first song and the introduction of the second song to the nth song. The process takes place.

When the music file is produced on the server, the music file may be produced by including an identifier according to an emotional parameter, and in this case, the terminal may extract the file by applying the emotional variable.

Embodiment of Digital Music Broadcasting Method

1 is a process flowchart of a digital music broadcasting method according to the present invention.

1) in the server, producing a music file for each predetermined category [200].

The category may be arbitrarily determined. You can decide by genre or theme. For example, it can be decided by genre such as ballad rock jazz marching song, or by theme such as love comfort song. It is apparent to those skilled in the art that an identifier for each category is set and included as a field of a music file.

2) Producing a music file by including the identifier according to the emotion variable in addition to the identifier for each category in the step of producing the music file [200].

Emotional parameter is defined as an identifier that determines the change of human emotion according to season, weather, day of the week, etc. This step is to classify in more detail in addition to the classification according to the genre or the theme as in step 1), and automatically extracts the corresponding song by automatically or artificially recognizing the season, the day of the week, the day and the night, etc. It is a step for.

3) transmitting the file to the terminal [201].

Since the server and the terminal are connected via the Internet, it is easy to transfer files. For example, a file may be pushed from a server to a terminal through a communication interface by a TCP / IP method, or the terminal may be connected to the server and downloaded in a pull manner.

In FIG. 1, a file stored in the server includes transmitting a new file to the terminal at regular update periods or from time to time when an update is necessary [203]. The server counts the update cycle and automatically sends the file to the terminal when it needs to be updated.

4) Downloading a file from the terminal [101] and classifying and storing the file according to the identifier [103].

The files downloaded to the terminal are sorted according to the identifier and stored in the memory. However, it will not matter if the files are stored in the memory at once without dividing the file into categories as in this step. Because the identifier is included in the file, only files corresponding to the desired classification can be extracted later.

5) If the user selects a category to listen to, extracting a file belonging to the category from the stored files [105].

When a user selects a desired category by operating the terminal, the terminal randomly extracts files belonging to the category. However, it does not matter whether it is extracted randomly but in the order of storage.

6) In the case of including the emotional variable in step 2), the terminal applies the emotional variable [106].

In addition to extracting files by genre or theme, it is a step of extracting corresponding files according to emotional variables. For example, since the current season, day of the week, or day and night can be counted in the CPU of the terminal, if the current is spring and Saturday, the file containing the emotional variable as an identifier may be automatically extracted. Of course, how to sort out music for spring Saturday night, for example, is a non-technical issue that designers can use to determine other sources.

On the other hand, since the terminal is difficult to recognize the emotion on the weather itself, it can be applied by the user input method. To this end, the terminal may provide various selection buttons regarding the weather (for example, rainy days, snowy days, cloudy days, sunny days, cold days, hot days, etc.) and allow the user to select them. However, it is also possible to install a sensor (temperature sensor humidity sensor barometric pressure sensor, etc.) that can detect the weather on the terminal itself to determine the current weather according to the output value of each sensor. This will also be included in the technical scope of the present invention as will be apparent to those skilled in the art.

7) playing the extracted file [107].

The terminal plays the song by reproducing the file extracted by the category or the emotional variable in a conventional manner as described above. The performance is continued by extracting the next song unless there is a separate stop command (stop command by the user or mechanical software interrupt) [109].

This step [107] is accomplished by a process that implements the natural concatenation of each file as shown in FIG. It demonstrates below. 2 is a process flow diagram illustrating a music reproduction method of the method according to the present invention.

First, song No. 1 is extracted from the memory of the terminal [113]. Since the extracted file is compressed in consideration of the transmission speed and the memory occupancy capacity, there should be a step of decompressing the file [115]. The decompressed file is played back in the normal manner [117]. When the file reaches the ending portion of the file after the playback proceeds, the ending part fades out. This can be easily done by digital sound processing (DSP).

On the other hand, there is a step different from the process of extracting, compressing and playing back the first track, and extracting the second track [121]. This is done in parallel processing. After extracting the extracted second song file [123], the introducing portion of the file is faded-in [125] to partially overlap the ending of the first song. Song 1 fades out and ends, and song 2 fades in and plays naturally.

Similarly, while song 2 is being played, song 3 is extracted and the above process is repeated, and this process is repeated up to n times.

Embodiment of the terminal

An embodiment of a terminal used in the aforementioned music broadcasting method will be described. 3 is an exemplary view of the external configuration of a terminal, which is composed of a monitor 11 and an operation keyboard 13. The monitor 11 is an element for displaying the operation state of the terminal, and serves to visually show the operating environment to the user. This can be done using LCD displays for notebook computers or CRTs for general PCs. The monitor 11 may also install a button that allows a user to select a desired category or emotional variable in a graphical user interface (GUI) manner. In addition, the graphic equalizer may be displayed and manipulated. Currently, programs that can display a graphic equalizer on the screen to adjust volume or tone and select a frequency band are well known. The operation keyboard 13 is a plate provided with buttons necessary for a user to operate the terminal, and can be easily designed and implemented by those skilled in the art according to the embodiment of the present invention.

4 is an internal configuration diagram of a terminal, and illustrates an internal configuration of the terminal at a device level.

In terms of the device, the terminal has a central processing unit (CPU) 17, a communication interface 15, an operating ROM (OP ROM) 19, a RAM (21), an acoustic processor (DSP) 23 ), A power amplifier (PA) 25, an interface unit (IF) 29, a monitor (display window) 11, an operation keyboard 13, and an HDD 31.

The CPU 17 directly controls communication functions, monitors, and memories, and performs operations and control management by codes of programs stored in the OP ROM 19. That is, when the first song is extracted by the instruction of the CPU 17 and transferred to the DSP 23, the CPU 17 decompresses and reproduces the second song, while the DSP 23 decompresses and plays back. .., command to extract song n.

The communication interface 15 is a dial-up modem of a telephone network and a modem supporting a CO-LAN network, and is a communication device used when downloading music files. The communication interface 15 need not be limited to the modem. If you use ADSL or leased lines without a telephone network, you can use a dedicated connection terminal (hub).

The RAM 21 is a basic memory where data is classified and processed. In addition, as will be described below, the file stored in the HDD 31 is loaded and temporarily stored. In this embodiment, a 16 MB DRAM was used. Therefore, a backup battery is needed.

The interface unit (IF) 29 is a coordinator for smoothly controlling and controlling the CPU and peripheral devices (HDD 31, DSP 23, keyboard 13, monitor 11) as a single IC. It is a component called a peripheral driver.

The HDD 31 is a large-capacity memory, and functions to store and read tens of thousands of files, and the file read here is transferred to the DSP 23 via the RAM 21.

The DSP 23 is a processor that decompresses a file that is a compressed sound source, fades out the end of the file, and fades in the intro of the next file. Once the file is delivered from the CPU 17, the DSP 23 decompresses and plays back, decompressing the next song for fade-in processing and superimposing both with the fade-in process of the previous song. It should be a version that can do parallel processing because it plays a role.

For the PA 23 and the speaker 27, knobs and buttons for operating the PA 23 (volume, timbre, reverb, etc.) may be included in the operation keyboard 13 in the appearance of FIG. In addition, the speaker 27 is provided with a connection jack to the terminal so that it can be connected as a separate external type. The PA and the loudspeaker are well-known components and will not be further described.

According to the present invention, since there is no cost of installing the wired network and the update of new songs is easy, the maintenance cost is low, and the music can be a true music broadcast by automatically extracting music suitable for the atmosphere by the genre or themes or by the emotional variables. It is possible to heighten the atmosphere of the place where the present invention is installed. This function of the invention can create a variety of uses. For example, the purpose of treatment in hospitals, preaching, listening to music for efficiency.
