Description

How to control recording and playback on a wireless terminal {RECORDING AND REPRODUCTION CONTROL METHOD FOR MOBILE TERMINAL EQUIPMENT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless terminal, and more particularly, to a method of controlling recording and playback in a wireless terminal that can be recorded and reproduced by embedding a recording device using a telephone answering design (TAD).

Recently, as the spread of wireless terminals has rapidly increased, the range of their use is increasing. Wireless terminals, such as mobile phones and wireless call receivers, add additional memory functions, such as phone number memory, clock functions, and answering functions, in addition to their original functions. However, there is a limit to the storage devices used for the storage device function, which results in poor data storage efficiency.

In addition to the additional functions described above, a wireless terminal with a recording function was developed, but it was limited to its use because it was only able to record the contents of a call during a call or to record when not in a call. There was room for development.

Accordingly, an object of the present invention is to provide a recording and playback control method with higher utilization in a wireless terminal to which a recorder function is added.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Implementing the function of the recorder using the TAD allows the amount of data to be recorded to be stored in a compressed form using a digital signal processor (hereinafter referred to as a DSP), which is highly efficient. In other words, when an audio signal input through a microphone passes through a codec, an analog signal is converted into a digital signal, and the converted digital signal is encoded by the DSP, stored in a storage location, and then controlled by the DSP. The digital signal is decoded at and the digital signal is converted into an analog signal by the codec, and the audio signal input through the speaker can be heard.

1 is a block diagram of a wireless terminal capable of recording and reproducing according to the present invention.

The controller 1 collectively controls the overall operation of the wireless terminal. That is, it controls the wireless communication function of the terminal and controls the recorder function according to the mode designation. The keypad 2 is a user interface means for generating commands for performing various functions including a dialing digit input by a user and a function of setting and releasing a recording or playback mode. The DSP 3 is connected to the control unit 1 and the first codec < RTI ID = 0.0 > (Coding & Decoding) < / RTI > 4, the memory 5 and the second codec 6 which will be described later. A digital signal input from the first codec 4 or the second codec 6 is encoded and stored in the memory 5, and the stored data is read and expanded to decode the first codec 4 or the codec. Output to the second codec (6). The first codec 4 is connected to the DSP 3, the microphone 7, and the speaker 8, and converts an analog signal input from the microphone 7 into a digital signal to control the controller 1. Outputs to the DSP 3 and converts the digital signal input from the DSP 3 into an analog signal under the control of the controller 1 and outputs the analog signal to the microphone 8. The memory 5 performs a function of storing data output from the DSP 3 under the control of the controller 1. The second codec 6 is used to perform the original function of the wireless terminal. The microphone 7 converts the voice signal into an electrical signal. The speaker 8 converts the electrical signal output from the first codec 4 into a voice signal and outputs the voice signal. The display unit 9 functions to inform the user when the original function of the wireless terminal is required. The reception message detection unit 10 performs a function of checking whether a message requesting the original function of the wireless terminal is received and informing the control unit 1.

1, the DSP 3, the first codec 4, and the memory 5 are components of the TAD and correspond to the means for forming the digital recording apparatus.

2 is a flowchart illustrating an operation control process of a wireless terminal capable of recording and reproducing according to an embodiment of the present invention, that is, a process of listening to recording and recorded data. In the following description of the recording and listening process according to an embodiment of the present invention in detail, only the components directly related to the present invention among the components of FIG. 1 and operations thereof are described. Jun.

When there is a function that requires recording and listening of voice data in the wireless terminal, in step a, the control unit 1 uses the keypad 2 to determine whether a command for setting a recording and reading mode has been generated. Scan In step b, recording or playback is performed according to the determination result. Specifically, in the recording mode, the voice signal input from the microphone 7 is converted into a digital signal by the first codec 4, and this signal is compressed and decoded by the DSP 3 to be fixed in the memory 5 for a predetermined time. Is stored during. In the listening mode, the speaker outputs the voice through the speaker 8 for a predetermined time through the opposite path. In this case, there should be no loss of voice data in case of recording and no inconvenience in listening in case of listening.

After the recording or playback is completed, the controller 1 checks the reception message detection unit 10 in step c to check whether there is a detected call message. If the call message is not detected, the controller 1 scans the keypad 2 in step d to determine whether a mode setting release command is generated. When the release command is generated as a result of the determination, the recording mode or the listening mode set in step a is canceled.

If there is a call message detected in step c, the call message is delivered to the display unit 9 in step e so that the display unit 9 displays the call message so that the user can confirm it. In step f, the controller 1 scans the keypad 2 and checks whether a specific key, for example, a call key, is input by the user. This is to check the user's intention to call, and the user who has recognized the presence of the call message displayed on the display unit 9 checks whether or not he / she is willing to talk to the caller at that time and records and plays back according to the result. To stop. This check is made for a limited time. If there is a call key input as a result of the check, go to step g to stop recording or playback, switch to a call mode, and perform a function of the wireless terminal. On the other hand, if the input of the call key is not detected, the process proceeds to step d to check whether the corresponding mode is terminated as described above.

The user's situation and usage of the wireless terminal may change from time to time, so if a call message is received while performing the recording or playback mode as described above, the fact is displayed on the display and the user displays the indication. It's even more useful to be able to choose whether to release recording or playback mode for reporting and calling or to continue recording or playback.

For example, if you are recording the content in an important meeting, you will need to continue recording without a call even if you receive a call message, but if you are recording while you are waiting for an urgent call, release the recording and call. There is room for the user to choose the action according to the situation.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention adds a voice recorder function using a TAD to a general wireless terminal, so that a user can store a voice that requires memory without having a separate recorder, and then listen to it again at a convenient time. And there is an effect that can improve the function.
