The present invention relates to a portable terminal, and more particularly, to a multimedia call recording method.

Currently, most commercially available terminals have a function of recording a desired content.

This feature allows the user to record notes that require notes or calls that they want to keep.

The prior art for this is presented in 1998 Utility Model Registration Application No. 26785.

This conventional technology is provided with a recording key for implementing an automatic recording function in an existing terminal to record the contents of a call for a predetermined time (for example, 15 seconds), and is a data structure for storing voice data of a predetermined time. Circular Queue is inserted into RAM that is mainly used as SRAM in existing terminals.

According to the configuration of the prior art, the automatic recording input is implemented by adding an item to the menu of the existing terminal as an input means by which the user can set the on / off and automatic recording time of the automatic recording function. Doing.

However, as the performance of the current terminal is improved, a call service using video will be provided.                         

Accordingly, since a video call will be widely used in the future, it is necessary to store a video, and further, an advanced technology for selectively recording a temporarily stored video call content and storing it in a terminal will be required.

Accordingly, the present invention provides a more convenient function by selectively recording the contents of the call based on the multimedia (one of the video / audio data, video data or audio data) according to the user's settings in order to meet the above requirements, the user's desire to purchase An object of the present invention is to provide a multimedia call recording method of a portable terminal, which is invented to improve the performance.

The present invention is to determine whether the recording mode is set before, during, or after the call in order to achieve the above object, and if the recording mode is set before and during the call call data (video + audio) ) Recording, and recording and playing the stored call data (video + audio) during the last call, if the recording mode is set after the call.

In the recording step after the call is terminated while storing the video / audio data separated from the current call data in the buffer (QUEUE), and determining whether to set the recording mode when the call is terminated Determining whether the recording mode is set; separating and playing the video / audio data from the previous call data stored in the buffer; and recording the video / audio data separated and reproduced. Characterized in that the process is made.

In the above-described recording data, video data and audio data separated from current or previous call data are selectively recorded (one of video / audio data, video data or audio data) according to a user's setting.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the embodiments of the present invention, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

A portable terminal for an embodiment of the present invention will be described assuming a multimedia video phone system developed based on the H.324 protocol.

1 is a block diagram of a multimedia call recording apparatus for an embodiment of the present invention, as shown here, a demodulator 110 for demodulating and transmitting call data for transmitting and receiving a call signal, and the demodulator 110 A signal synthesizer / separator 120 for separating the demodulated call data into video / audio / information data, synthesizing video / audio / information data to be transmitted, and transmitting the synthesized video / audio / information data to the demodulator 110; A video codec 140 for decoding the video data separated by the separation unit 120 into an image signal, encoding the video signal of the user into video data, and transmitting the video signal to the signal synthesis / separation unit 120; The audio codec 150 decodes the audio data separated by the unit 120 into voice data, encodes a user's voice signal into audio data, and transmits the audio signal to the signal synthesis / separator 120. And an information data processor 160 for decoding the counterpart information included in the received call data, encoding the user information to be included in the transmitted call data, and transmitting the encoded information to the signal synthesizer / separator 120 and the signal synthesizer / separator. A buffer 130 for storing the transmission video / audio / information data to be synthesized in 120 and the received video / audio / information data separated in the signal synthesizing / separation unit 120, and a user setting before a call. Or a recording unit 170 for recording one of video / audio data, video data, and audio data of a predetermined time stored in the buffer 130 by a user key input during a call or at the end of a call.

The signal synthesizer / separator 120 is configured of a multiplexer / demultiplexer of H.223 standard.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

In the embodiment of the present invention, the processing of the video and audio data to be transmitted to the counterpart and the processing of the video and audio data received from the counterpart are opposite operations. I will explain only.

First, the demodulator 313 demodulates a call signal received from a call channel and stores the demodulated signal in the buffer 130 and transmits the same to the signal synthesis / separator 120.

At this time, the signal synthesizing / separating unit 120 separates the call signal synthesized by a predetermined rule according to the H.223 protocol into information data including video data, audio data, control signals, and the like, and the video codec 140 and the audio codec. 150, the information data processor 160 transmits the data.

Accordingly, the video codec 140 decodes the video data and transmits the original video signal to a display device (not shown), and the audio codec 150 decodes the audio data to transmit the original audio signal to the audio device (not shown). Information data processor 170 decodes information such as a control signal from the information data.

Therefore, the user makes a call while listening to the voice while watching the video of the other party.

In addition, the present invention transmits the call data (video + audio) received from the other party to a demultiplexer of the H.223 standard, and stores it in a queue, which is a kind of buffer.

Therefore, when the user sets the recording after the call, it is possible to record a certain amount of content already called.

If the user presets before the call or the user inputs the record key during the call, the content of the current call may be recorded by a desired amount.

First, the case where the recording mode is set before the call and the recording mode is set during the call in the embodiment of the present invention will be described.

When the call data received from the other party is stored in the buffer 130 and separated into the video data, the audio data, and the information data in the signal synthesizing / separating unit 120, the recording unit 170 controls from a control unit (not shown). The video data and audio data are recorded in the above by checking the recording mode preset by the user or the recording mode currently set by the user as a signal.

In this case, video data and audio data are simultaneously recorded or selectively recorded.

In the embodiment of the present invention, a case in which the user sets the recording mode after the call will be described.

The call data received from the other party is stored in the buffer 130 and divided into video data, audio data, and information data in the signal synthesis / separation unit 120, and thus the video codec 140, the audio codec 150, and the information data processing unit. By being processed in step 160, the user can hear the contents of the call while watching the video of the other party.

At this time, the buffer 130 stores the data as a queue, and when the data is full, stores the new call data from the first position.

Subsequently, if the user sets the recording mode when the call is terminated, the signal synthesizing / separating unit 120 reads the call data stored in the buffer 130 for a predetermined time and divides the video data into audio data and information data. By transmitting the separated data to the video codec 140, the audio codec 150, and the information data processing unit 160, the user can check the contents of the call with the other party.

Accordingly, the recording unit 170 checks the recording mode currently set by the user by inputting a control signal from the controller (not shown), and separates the video / audio data, the video data, and the audio separated from the signal synthesizing / separating unit 120. One of the data will be recorded.

On the other hand, it has been described as recording the other party's video and / or audio, but can also record the voice of the user corresponding thereto.

As described in detail above, the present invention has an effect of selectively recording the video call contents desired by the user according to the user's setting at the time desired by the user, thereby improving the utilization of the limited memory in the multimedia-based video phone.
