The present invention relates to a song half cycle with an operating system (OS: Operating System) installed, and more particularly, to configure a song half cycle with different OS modules each having an operating system installed therein, and to process audio data (eg, song accompaniment output, Real-time processing such as melody adjustment, tempo change, etc., image data processing (e.g., background display, lyrics display, score display, etc.) and other data processing (e.g., Internet access, music reservation, etc.) It is related to the half cycle of the song based on the dual operating system, in which each OS module independently processes the same general processing requirements.

A song half cycle [aka karaoke] is a device that outputs accompaniment [audio data] and specific video data [background, lyrics, etc.] of songs selected by the user among the songs stored in the device. You will use the microphone to sing along as you watch the lyrics displayed on the screen and listen to the accompaniment output from the speakers. In addition, the song half-cycle includes features such as song reservation, song search, melody control, tempo change, pitch change, and score display.

In general, song accompaniment uses MIDI or digital audio (such as MP3) to compose song accompaniment, which must be handled properly at the correct time. In particular, if the rhythm change, measure management, paragraph management, etc. changes the current song accompaniment, sophisticated control is required to prevent the accompaniment breaks or beats due to the change in the song accompaniment.

On the other hand, as mentioned above, the half-cycle of the song is equipped with functions such as tempo change and pitch change, but recently, due to the development of multimedia / communication technology, people have added various functions such as internet access, song update, and recording data storage. I'm asking for it.

In the half-cycle of a song installed with a general-purpose OS according to the prior art, a task method or an interrupt method is used to deal with matters requiring real-time processing such as maintaining the accuracy of the accompaniment, changing the rhythm, and managing the MIDI / verse. .

By the way, while the conventional technique such as the above can achieve a certain level of performance using a high performance CPU in performing the accompaniment beat accuracy, it is difficult to implement functions such as rhythm conversion, node management, clause processing, tempo processing, and the like. There is a very difficult problem. Therefore, in the related art, it takes a considerable time to perform a song accompaniment related function, and there is a problem that affects the performance of the function by performing another function when performing the function.

Meanwhile, a half-cycle of a song in which a Real-Time Operating System (RTOS) is installed as a conventional technology is also released.

However, in the half-song of the RTOS installed above, it is possible to properly perform real-time processing such as maintaining the beat accuracy of the accompaniment, changing the rhythm, managing the MIDI / verse, etc. There are many limitations in installing / running a program due to the characteristics of RTOS. This demands a lot of time and money because the half-cycle users (or vendors) must rely on the RTOS to add new functions, install new devices, and run new programs.

Accordingly, in recent years, an operating system (OS) has been installed in the song half cycle so that various additional functions can be easily implemented in the song half cycle and the song accompaniment can be precisely processed. As such, the half-cycle of the song is installed with an operating system of either a general-purpose OS or RTOS, and the matters to be processed in the song half-cycle, that is, the real-time processing and the general processing, are processed independently of each other in the corresponding operating system to implement the function of the song half-cycle. There is an urgent need for technology to further increase efficiency.

The present invention has been proposed in order to solve the above problems and meet the above requirements, and to configure the song accompaniment by different OS modules, each operating system is installed, audio data processing (for example, song accompaniment output, Matters that require real-time processing such as melody adjustment, tempo change, etc., image data processing (e.g., background display, lyrics display, score display, etc.) and other data processing (e.g. Internet access, music reservation, etc.) The purpose is to provide a half cycle of the song based on the dual operating system, in which each OS module can handle the general processing requirements such as those independent of each other.

An embodiment of the present invention for achieving the above object, in the song half-period installed operating system (OS), a first OS module for processing a matter that requires real-time processing including audio data processing; A second OS module for processing a matter requiring general processing including image data processing; And a data communication unit for data communication between the first OS module and the second OS module, wherein the first OS module and Each of the second OS modules may process corresponding items independently of each other using its own operating system.

On the other hand, according to another embodiment of the present invention, in the singing cycle period, the first OS module is configured in the singing period, and the second OS module is configured in the computer, wherein the song half cycle is the data communication unit Instead of providing the data, the communication means provided in the computer and the communication means provided in the first OS module are used to transmit and receive data between the first OS module and the second OS module.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

Process in real time (audio data processing) in RTOS module, but independent in general purpose OS module.

On the other hand, a feature of another embodiment of the present invention is that the general purpose OS of the above embodiment in a computer (eg, PC, notebook, etc.) capable of communicating with the song half cycle by configuring only the RTOS module in the song half cycle without configuring the general purpose OS module in the song half cycle What the module does is independent of the RTOS module.

For example, in the present invention, the matters that should not be processed after a certain time delay such as song accompaniment output, melody output, melody adjustment, tempo adjustment, etc. (audio data processing matters) are processed by the RTOS module, a background image display, Even if there is a slight time delay from the current point of time, such as lyrics display, score display, internet access, and song reservation, the general OS module handles the matters that need to be handled somehow (image data processing and other data processing).

The general processing mentioned above includes image / other data processing, for example, background display, lyrics display, score display, internet access, data storage, song reservation, etc., and real-time processing includes audio data processing. For example, song accompaniment outputs, melody adjustments, and tempo changes.

On the other hand, in another embodiment of the present invention, the song half-cycle may be configured by two general-purpose OS modules or the song half-cycle may be configured by two RTOS modules without configuring the song half-cycle by the general-purpose OS module and the RTOS module. However, when the song half-cycle is composed of OS modules (two general purpose OS modules or two RTOS modules) of the same operating system as described above, the first general purpose OS module is processed in real time and the second general purpose OS module is processed. Allow general processing to be handled. Similarly, when the song half-cycle is composed of two RTOS modules, the first RTOS module is processed in real time and the second RTOS module is processed in general.
