The present invention relates to a broadcast receiving terminal, and more particularly, to separate and store an audio signal from a received digital broadcast, and to utilize the stored audio signal as an audio item in the broadcast receiving terminal. It relates to a receiving terminal.

As digital multimedia broadcasting (DMB) broadcasting capable of mobile reception becomes visible, demand for a portable broadcast receiving terminal equipped with a mobile reception function is increasing. In particular, as a terminal capable of receiving broadcasts, in particular, a mobile communication terminal provides functions such as photographing and video shooting, and is transforming into a representative device expressing individuality of personality beyond the concept of communication. In the future, the terminal is expected to develop as a device having a complex function such as multimedia playback as well as various communication functions as well as a broadcast receiving terminal function.

A broadcast receiving terminal capable of receiving broadcast content includes an audio control unit that performs an audio control function of the terminal itself, in addition to the broadcast receiving control unit that receives a broadcast.

For example, a broadcast receiving terminal capable of mobile communication has a function of receiving and expressing content of a broadcast. In addition to the above function, the broadcast receiving terminal is a mobile communication terminal as a communication reception notification tone (hereinafter referred to as a ringtone) and an alarm sound. It may have a function to control audio, such as. Accordingly, the mobile communication reception notification sound (ring tone) may be expressed by the audio controller of the terminal itself, and an alarm function may be provided to the user. If the terminal can only receive the broadcast may have a function that can express the alarm sound. In this case, the function of receiving and expressing a broadcast and the audio control function of the terminal itself are separated in the terminal.

Hereinafter, a broadcast reception control function and an audio control function of a conventional terminal will be described using an example of a broadcast terminal combined with a mobile terminal capable of mobile communication.

In the terminal, an area capable of decoding a received broadcast and an area storing an external sound source are separated. That is, the broadcast reception control unit and the audio control unit of the terminal itself are separately configured in the terminal.

In the audio decoding region of the broadcast reception controller, when a broadcast signal is input through airwaves, the input signal is demodulated. When the demodulated received signal is decoded into an audio signal, the music content of the broadcast content is restored to an audible sound and transmitted to the user.

 On the other hand, in the communication terminal area of the terminal, an external sound source may be recorded, or audio may be stored through a download method from a sound source service company. The stored sound source or audio is used as an audio item in the terminal such as an alarm sound, a ring tone, a communication connection sound, or a disconnect sound in the communication terminal.

Referring to FIG. 1, a broadcast receiving terminal for a conventional mobile communication terminal will be described as follows.

1 is a block diagram showing the structure of a broadcast receiving terminal for a mobile communication terminal with a mobile communication function. In FIG. 1, the broadcast receiving unit 100, the system decoding unit 200, the audio decoding unit 400, and the first auxiliary memory device 500 are broadcast reception control units of a terminal, and a second auxiliary memory device 550 and an encoder ( 600), the external sound source 700, and the audio item processing unit 800 are audio control units of the terminal. The memory unit 300 is shared and used by the broadcast receiving control unit and the audio control unit.

In the broadcast reception control unit of the terminal, the broadcast reception unit 100 receives a broadcast stream, demodulates it, and converts it into a bit stream. The bit stream is input to the system decoder 200 and is divided into an audio stream, a video stream, and a data stream, and output. In the case of DMB broadcasting, the system decoder 200 uses an MPEG-2 TS (Moving Picture Expert Group-2 Transport Stream) decoder, an Eureka-147 (European Research Coordination Agency progect-147) decoder, or the like. The separated audio, video, and data streams are input to the memory unit 300 in the form of a compressed file and stored together. The stored file is again stored in a separate first auxiliary storage device 500. In an embodiment of the first auxiliary memory device 500, a nonvolatile memory device may be used. If the stored audio file is reproduced, the audio file stored in the first auxiliary storage device is again output to the memory unit 300 and then input to the audio decoder 400. The audio decoder 400 decodes the input file, converts the input file into an audible sound, and transmits the audible sound to the outside through the audio output unit. The audio decoder uses an MPEG-4 bit sliced arithmetic coding (BASC) or a masking pattern adapted universal subband integrated coding and multiplexing (MUSICAM) decoder according to a compressed file format.

On the other hand, if the ringtone is stored in the audio controller of the area of the mobile communication terminal through the outside, the ringtone of the audible range input through the external sound source 700 is input to the recording unit 600 is encoded in the form of a compressed file. The encoded ring tone signal is stored in the second auxiliary memory 550. Similarly, a nonvolatile memory device may be used as the second auxiliary memory device. If the stored ringtone signal is reproduced as a reception notification sound on a communication, first, an audio signal file of a ringtone stored in the second auxiliary storage device 550 is converted into a ringtone in an audible range through the audio item processing unit 800. After conversion, it is output to the outside. In addition, even if an alarm sound is input through an external sound source, the same process as described above is performed.

As described above, the conventional broadcast reception terminal has its own audio control function and broadcast reception control function separated from each other. That is, in the case of FIG. 1, the first auxiliary memory device and the second auxiliary memory device are physically divided separate memory devices. In addition, even if the first auxiliary storage device and the second auxiliary storage device are physically configured as one storage device, the storage area is separated therein, and each of the separated areas is the audio control unit and the broadcast reception control unit of the terminal itself. Separate access rights are assigned to each control unit to control only its own storage area. Therefore, the audio control unit and the broadcast reception control unit of the terminal itself are not given access rights to each other's storage area, so that even one storage device may be used as a separate storage device.

Therefore, when the broadcast content is received using the broadcast receiving terminal, the received broadcast content is controlled only by the broadcast receiving control unit and is not controlled by the audio control unit of the terminal itself. There was a problem that can not be directly used as an audio item (item) such as a ringtone or an alarm sound (alarm).

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and an object of the present invention is to receive broadcast content, store an audio signal therein, and utilize the stored audio signal as an audio item in an broadcast receiving terminal. It is to provide a broadcast receiving terminal that can be.

In order to solve the above problems, the present invention provides a broadcast reception control unit for receiving and decoding broadcast content; An audio controller which processes an external sound source or its own sound source and outputs it as an audio item; And a storage device in which an audio signal of the broadcast content received by the broadcast receiving control unit and an audio item of the audio control unit are stored in a file form and accessible by any of the broadcast receiving control unit and the audio control unit. A broadcast receiving terminal is provided.

 The terminal converts the audio signal file format of the received broadcast content into the audio item file format in the terminal when the format of the audio signal file of the broadcast content stored in the storage device is different from that of the audio item file in the terminal. It is preferable to further include an audio format converter.

In addition, since many mobile communication terminals are capable of receiving broadcasts, it is preferable that the above-mentioned broadcast receiving terminals are both mobile communication terminals, and in the case of a broadcast receiving terminal which is also a mobile communication terminal, it is stored in the storage device. It can be used as a communication reception notification sound, ring tone, alarm sound.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. The same components as the prior art are given the same names and the same reference numerals for convenience of description, and detailed description thereof will be omitted. 2 is a block diagram showing the internal structure of a broadcast receiving terminal according to the present invention.

The configuration of the broadcast receiving terminal according to the present invention is similar to that of the conventional terminal of FIG. However, the broadcast receiving control unit of the terminal and the audio control unit of the terminal itself are accessible to both the audio signal file of the broadcast content and the auxiliary storage device for storing the audio item file in the terminal. Therefore, it is preferable that the auxiliary storage device is not physically separated but is integral.

When the broadcast stream is input to the broadcast receiver, the receiver 100 demodulates the input broadcast stream and outputs it in the form of a bit stream. The output bit stream is input to the system decoder 200 and separated into audio, video, and data signals, and then stored in the memory unit 300. The data stored in the memory unit 300 are stored in the auxiliary memory device 500 again. The auxiliary memory device 500 may be any storage device that continuously stores data even when the terminal is powered off. In the present invention, a nonvolatile memory device is used. The existing PVR (Personal Video Recorder) function allows the bit stream of video broadcasting to be stored together in the storage device without separating the audio and video, and the audio and video are played together. However, since the present invention is to use an audio signal of the broadcast content as an audio item in the terminal by using the broadcast receiving terminal, the video, audio, and data streams are separated, and the audio stream is different from other streams in the auxiliary storage device 500. It is preferably stored separately.

The format in which the audio stream is stored may be converted into a storage format of an audio item in the terminal through the audio format converter 900, or may be stored in the form of a compressed file transmitted as broadcast content.

Therefore, if the transmission content of the broadcast content is stored as it can be stored in various compressed file formats such as MPEG-4 BSAC, MUSICAM, Musical Instrument Digital Interface (MIDI). Once stored in the memory unit 300, the stored files are moved to the auxiliary memory device 500 and stored. Since the auxiliary memory device 500 can access both the audio control unit and the broadcast reception control unit of the terminal, it is preferable that the auxiliary memory device 500 be physically configured as one.

In addition, even if two or more auxiliary storage devices are separately configured in the terminal according to the present invention, each control unit may be configured to access all the auxiliary storage devices.

 Hereinafter, a process in which an audio file of broadcast content received and stored in the above process is used as an audio item of the terminal will be described. The audio item may be a ring tone or an alarm sound when the broadcast receiving terminal also has a function of a communication terminal. That is, it is a concept that includes all of the audible audio signals that can be used in the terminal itself except for expressing the received audio by broadcast reception. Assuming that an audio item is a ringtone, a process in which an audio signal of the stored broadcast content is used as a ringtone of a communication terminal through the terminal according to the present invention is as follows.

 If the ringing is made by the communication reception signal, first, if the format of the stored audio file is stored in a format different from that of the broadcast content, the stored audio file must be converted into the format of an audio item of the communication terminal. do. Therefore, if the transmission format of the broadcast content is MPEG-4 BASC and the ringtone is stored in the MP3 form, the audio signal of the broadcast content of the MPEG-4 BASC format stored in the auxiliary storage device 500 is input to the memory unit 300. The input audio signal is output to the audio format converter 900. The audio format converter 900 converts, for example, an audio signal file of broadcast content according to a format output to a ringtone. For example, the broadcast content audio signal of the MPEG-4 BASC format is converted into a ringtone of the MP3 format and then output through the audio item processing unit 800 through the memory unit 300. The audio item processing unit 800 may convert the input audio item into an audible sound of a selected function to notify the terminal user of the communication reception.

 The format of the stored audio file is already stored in the form of an audio item via the audio format converter 900, or the transmission format of the broadcast content may be transmitted in the same format as the audio item. In such a case, the audio signal of the broadcast content stored in the auxiliary storage device 500 may be directly input to the audio item processing unit 800 and converted into an audible sound without being passed through the audio format converter 900 and used as a ringtone of the communication terminal. Therefore, not only music provided as broadcast content but also sound effects expressed in dialogue lines or other broadcasts may be used as ringtones. The technical idea according to the present invention is not limited to any broadcast receiving terminal, but can be implemented in any broadcast receiving terminal to which the above technical idea can be employed, and such an embodiment should be said to fall within the claims of the present invention. will be.

Referring to the effects of the broadcast receiving terminal according to the present invention described above is as follows.

In the case of receiving broadcast contents using the broadcast receiving terminal according to the present invention and using it as an audio item in the terminal, it is possible to use the terminal differently according to an individual, and to use the terminal as a popular culture. Can express various concepts.
