While in charge of the control, in accordance with the present invention supports a broadcast recording mode for receiving the airwave broadcast or broadcast content using data communication to record a video file, and receiving the airwave broadcast in the broadcast recording mode to record a program When receiving a report that the broadcast signal strength of the over-the-air broadcast is weakened from the broadcast receiving module 100, a broadcast service method is used to receive broadcast contents using data communication to record a program, thereby controlling to continuously record. Do it.

Here, the main controller 20 includes an encoder and a decoder, and extracts video content from the wireless signal received through the wireless transceiver 10 to convert the digital content into digitized broadcast content data or vice versa. do.

The memory unit 30 is composed of a nonvolatile memory, and stores an operating system of the mobile communication terminal, various application programs, a video file generated in a broadcast recording mode, or various data generated during operation of the mobile communication terminal.

The video processing unit 40 converts the broadcast content data downloaded through data communication under the control of the main control unit 20 into an analog audio signal through the audio processing unit 41 in the case of the audio data, and in the case of the video data, the video processing unit. After compression and processing through 42, output to the amplifier 50 or the liquid crystal display driver 70, or stored temporarily.

The amplifier 50 receives the analog audio signal received from the audio processor 41 or the broadcast receiving module 100 of the video processor 40, amplifies the signal to a predetermined level, and outputs it through the speaker 60. The driver 70 processes the image data processed by the video processor 40 or the image data of the over-the-air broadcast received through the broadcast receiving module 100 and outputs the processed image data through the LCD screen 80. The key input unit 90 Receives various data and commands from the user.

The broadcast receiving module 100 includes a television or radio receiving module for receiving an over-the-air broadcast, a DMB module for receiving a satellite signal according to a digital multimedia broadcasting service, and the like, and receives an analog broadcast signal received through a broadcasting antenna. Transmit and perform demodulation, demodulation, and the like, and transmit the digitized airwave broadcast data to the main controller 20, and the image data of the digitized airwave broadcast data is transferred through the liquid crystal display driver 70. The voice data is output to the speaker 60 through the amplifier 50 as an analog voice signal itself.

In addition, the broadcast receiving module 100 measures the broadcast signal strength of the over-the-air broadcast at predetermined time intervals and reports it to the main controller 20 while receiving a over-the-air broadcast in a broadcast recording mode and recording a program according to the present invention. .

Referring to the operation of the present invention configured as described above, first, the user moves the menu through the operation of the key input unit 90 in the mobile communication terminal to switch to the broadcast recording mode (S10), the user in the broadcast recording mode Designate program, recording time, name of video file to save.

In the present invention, since a separate service fee is charged when storing the downloaded broadcast content using data communication or recording a program according to a digital multimedia broadcasting service, while listening to an over-the-air broadcast, which usually does not require a separate fee. It is assumed that the user first attempts to record a program.

The present invention can also be applied to recording radio broadcasts, in which case the same processing as for recording a television program is carried out except for the part processing the image data.

When the broadcast recording mode is switched, the broadcast reception module 100 performs the band conversion, demodulation, etc. of the analog broadcast signal received through the broadcast antenna under the control of the main controller 20 to digitize the airwave broadcast data. After generating, the image data is output to the LCD screen 80 through the LCD screen driving unit 70 and the audio data is received in such a manner as to output the analog voice signal itself to the speaker 60 through the amplifier 50. Play the program.

In this case, the airwave broadcasting data generated by the broadcast receiving module 100 is also transmitted to the main control unit 20. The main control unit 20 performs compression or the like on the main control unit 20 to process the currently playing program in real time. Program recording is performed by temporarily storing in the designated area 30 (S11).

While recording the program as described above, the broadcast receiving module 100 measures the broadcast signal strength of the over-the-air broadcast received through the broadcast antenna at predetermined time intervals (S12), and whether the reception state of the broadcast signal is good. Determine and report to the main control unit 20 (S13).

That is, the broadcast receiving module 100 determines whether the broadcast signal strength is good according to a preset reference such that the broadcast signal strength of the received over-the-air broadcast is weakened to a reference level or less, or such a duration lasts for a predetermined time. If the main control unit 20 reports and receives the report that the reception state of the airwave broadcasting is good, the main control unit 20 checks whether or not the recording of the corresponding program is completed (S14). If the recording is not completed, the process (S11). S14) is repeatedly stored to temporarily store over-the-air broadcast data in a designated area of the memory unit 30, and when recording is completed, the recorded data for the corresponding program is stored as one video file in another area of the memory unit 30. Store in (S15).

On the other hand, as a result of the determination in step S13, when the broadcast reception module 100 reports that the reception state of the airwave broadcasting is not good, the main control unit 20, the main control unit 20 is broadcast using data communication Receive a broadcast in a manner of downloading the content to ask the user whether to continue recording the program (S16), and when the user requests to receive a broadcast using the data communication broadcast service using the data communication in conjunction with the mobile communication network After connection (S17), the broadcast content data is downloaded according to the connected broadcast service, processed by the video processing unit 40, and temporarily stored (S18).

Here, the main control unit 20 requests the subscriber information such as whether the user is subscribed to the data plan or whether the user can receive the current data communication service through the mobile communication network, and responds to the mobile communication network with a response message. Since the broadcast signal strength of the over-the-air broadcast is poor to the user by using the subscriber information received from the user, the message window is queried whether the program recording is continued while receiving the broadcast by switching the service method using data communication.

In this case, a separate detailed function may be designated in activating the message window by 'always query every time service switching', 'query only when data plan is not unlimited', and 'switch service without query'.

If the user does not request the program recording using data communication with respect to the query of the activated message window, the user returns to the process of storing the airborne broadcast data (S11 to S14), and continuously records the program by receiving the airwave broadcast. Otherwise, when requesting program recording using data communication, a data link is established with a content provider using a mobile communication network to connect a broadcast service using data communication.

At this time, the main control unit 20 first checks the 'program to be recorded' designated by the user when the broadcast recording mode is switched, and requests the content provider to provide the same broadcast content as the program currently being recorded.

Then, the main control unit 20 controls to perform data communication through the mobile communication antenna and the wireless transmission and reception unit 10, extracts the video content from the wireless signal received from the content provider and converts it into digitized broadcast content data In addition, the video processing unit 40 converts the broadcast content data into an analog audio signal through the audio processing unit 41 in the case of audio data, compresses and processes the video data through the video processing unit 42 in the case of video data, and temporarily stores the data. Done.

At this time, the main control unit 20 checks whether the recording of the program is completed (S19), and when the recording is completed, the data recorded for the program is stored in the memory unit 30 as one video file (S15).

Meanwhile, even while downloading and temporarily storing broadcast content data from the content provider through the wireless transceiver 10, the broadcast receiving module 100 continuously checks whether the reception state of the over-the-air broadcast is good at predetermined time intervals and then controls the main control unit. If the reception state of the over-the-air broadcasting is not good while the recording is not completed, the video processing unit 40 processes the downloaded broadcast content data using data communication to temporarily record the recording. Save (S19, S20).

On the other hand, if the reception state of the over-the-air broadcasting from the broadcast receiving module 100 is reported to be good in step S20, the main control unit 20 terminates the connection of the broadcast service using the data communication, through the over-the-air antenna Receives a broadcast and temporarily stores it in a designated area of the memory unit 30 as over-the-air broadcast data, and controls to measure the broadcast signal strength of the over-the-air broadcast received by the broadcast receiving module 100, thereby ensuring that the reception state of the over-the-air broadcast is good. It checks whether the recording is completed according to whether or not to generate and store one video file (S21).

On the other hand, when the recording of the broadcast program is completed, according to the step (S15) to store the data recorded for the program in the memory unit 30 in the memory unit 30 as a single video file, broadcast over the air wave When the program is recorded, the reception state is poor, and when the broadcast content provided in real time through data communication is received and the broadcast program is continuously recorded, the service is switched when the over-the-air broadcast data is stored in the designated area of the memory unit 30. By storing the time information or the frame information of the airwave broadcasting data at the time point, after the recording of the broadcast program is finished in the main control unit 20 based on the information, the airwave broadcasting data and the broadcast content data are combined to generate a single video. It is stored in the memory unit 30 as a file.

As described above, the present invention provides a mobile communication terminal that provides a function of watching television or listening to a radio. If it is impossible to record continuously, it automatically sets up the data link to receive broadcast contents provided in real time through data service to create a single video file. Switches to another good service method to continue recording, and there is an effect of continuously recording the corresponding program even when the service method is switched.
