BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a configuration of a video / audio recording system according to an embodiment of the present invention.

Referring to FIG. 1, a video telephone 110 is a terminal for performing video communication by calling a counterpart terminal and performing video communication with a counterpart terminal through the secured communication channel when the communication channel is secured by the attempt to be.

To this end, the video telephone 110 calls a counterpart terminal at the request of the user to attempt video communication, and connects the communication channel for video communication in response to the counterpart terminal. The counterpart terminal may be a broadcast server 120 supporting a video communication service. In this case, the video telephone 110 uses a unique number assigned to the video communication receiving module 122 provided in the broadcasting server 120 in order to attempt video communication with the broadcasting server 120. That is, the user inputs the unique number assigned to the video communication receiving module 122 using the video phone 110, and attempts video communication.

If the video communication is permitted in response to the video communication attempt, the video phone 110 transmits the identification information of the personal video recording apparatus to record video and audio information to be transmitted in the future after forming a communication channel. The identification information of the personal video recording apparatus is used to identify the personal recording apparatus for transmitting the video and audio information to the broadcasting server 120. However, the broadcasting server 120 can identify the personal recording apparatus to which the video and audio information is to be transmitted without using the identification information of the personal recording apparatus.

For example, if the broadcasting server 120 provides a telephone number of a calling party, the broadcasting server 120 identifies the user of the video telephone 110 by the calling party telephone number, You can find the individual recording equipment.

Also, the broadcasting server 120 performs a personal authentication procedure to provide a recording service of video and audio information, and the broadcasting server 120 can confirm the authenticated user through the authentication procedure. Accordingly, the broadcast server 120 can find the registered personal recording apparatus corresponding to the user identified in the authentication procedure.

Then, the video phone 110 transmits video and audio information or pre-stored video and audio information acquired through the camera and the microphone through the formed communication channel. When the transmission of the video and audio information is completed, the video phone 110 releases the formed communication channel. The completion of the transmission of the video and audio information may be terminated automatically when the video communication is terminated at the request of the user or when the transmission of all the video and audio information to be transmitted is completed.

Meanwhile, the video phone 110 receives information on the recording result corresponding to the video and audio information that has been transmitted, and informs the user of the information on the received recording result through the user interface. Here, the information on the recording result is provided using a voice guidance service (ARS service), a text service, or the like.

In addition, the video phone 110 can receive information on the video phone 110 by using a voice guidance service (ARS service), a text service, or the like even when recording is not permitted by the personal video recording apparatus 130.

In this case, the video phone 110 can instruct the broadcasting server 120 to store video and audio information. That is, the video phone 110 may store the video and audio information transmitted by the video server 110 to the broadcasting server 120, instruct the video server 110 to retry recording at a possible point in time, or instruct the end of the video communication.

If the video phone 110 instructs to retry recording, it continues to transmit video and audio information but does not retry recording, it ends the transmission of video and audio information.

The communication network 140 is a network for providing a communication service between the video phone 110 and the broadcasting server 120. That is, the communication network 140 forms a communication channel between the video telephone 110 and the broadcasting server 120, and transmits video and audio information transmitted from the video telephone 110 through the formed communication channel to the broadcasting To the server (120).

For this, the communication network 140 calls a corresponding terminal according to a unique number provided from the video telephone 110 when there is a video communication attempt from the video telephone 110. The communication network 140 is a network capable of providing a video communication service, and may be defined differently depending on the type of the video phone 110. That is, when the video telephone 110 is a telephone using a wired network, the communication network 140 may be a wired network supporting video communication services. Otherwise, if the video telephone 110 is a telephone using a wireless network, the communication network 140 may be a network in which a wireless network supporting a video communication service is combined with a wired network.

The communication network 140 forms a communication channel between the video phone 110 and the broadcasting server 120 when the corresponding terminal in which the video communication is attempted, i.e., the broadcasting server 120, requests the video communication. The communication network 140 transmits video and audio information provided from the video telephone 110 to the broadcasting server 120 through the formed communication channel. The communication network 140 releases the communication channel when the video telephone 110 is requested to terminate the video communication.

Meanwhile, the communication network 140 provides the video phone 110 with information about a recording result using an ARS service, a text service, or the like in response to a request from the broadcasting server 120.

When the broadcast server 120 receives a video communication request through the communication network 140, the broadcasting server 120 transmits a response message corresponding to the request. When a communication channel for video communication is formed by the communication network 140, the broadcasting server 120 transmits identification information of a personal video recording apparatus to record video and audio information to be received in the future through the formed communication channel, And can receive it from the telephone set 110.

The broadcast server 120 confirms the target personal recording apparatus 130 to record video and audio information according to the identification information of the personal video recording apparatus 110 received from the video phone 110.

The broadcast server 120 requests the personal recording apparatus 130 to record a video. The broadcast server 120 transmits the channel information requesting the recording to the personal recording apparatus 130 when requesting the recording.

However, the recording may be rejected by the personal recording apparatus 130 in response to the recording request. In this case, the broadcasting server 120 notifies the video phone 110 of the fact that the recording is rejected from the personal recording apparatus 130, using an ARS service, a text service, or the like.

The broadcasting server 120 can receive video and audio information from the video phone 110 even if the recording is rejected by the personal video recording equipment 130. [ This is to transmit the received video and audio information to the personal video recording apparatus 130 if recording is permitted by the personal recording apparatus 130 in the future.

In the situation where the recording is rejected as described above, the broadcasting server 120 may be configured to continue or stop the video and audio information according to an instruction of the video phone 110.

Meanwhile, the broadcast server 120 may not receive any response from the personal recording apparatus 130 in response to the recording request. That is, if the power of the personal video recorder 130 is turned off or a problem occurs in connection with the personal video recorder 130, no response can be received from the personal video recorder 130. The broadcasting server 120 may continuously monitor the status of the personal recording apparatus 130 to check the status of the personal recording apparatus 130 in advance. If the status of the personal recording apparatus 130 is not recordable in advance, the broadcast server 120 notifies the video phone 110 that recording is not possible without requesting recording to the personal recording apparatus 130 Can be reported.

The broadcasting server 120 receives video and audio information from the video phone 110 through the formed communication channel. The broadcasting server 120 transmits the video and audio information received from the video telephone 110 to the personal video recording apparatus 130. [

The broadcast server 120 may perform a personal authentication procedure for the video phone 110 before receiving the video and audio information from the video phone 110. [ This is to prevent information from being recorded indiscriminately by a person who is not a legitimate user.

The broadcast server 120 may transmit or store the video and audio information received from the video telephone 110 to the personal video recording apparatus 130 in real time while video communication is being performed, and may transmit the video and audio information when necessary.

Meanwhile, the broadcasting server 120 modulates the video and audio information according to a predetermined modulation scheme and transmits the modulated video and audio information to the personal recording apparatus 130. At this time, the broadcasting server 120 preferably modulates video and audio information according to a modulation scheme supported by the personal video recording apparatus 130. Typically, the personal video recording apparatus 130 supports a modulation scheme such as an Internet protocol unicast (IP Unicast) scheme and a quadrature amplitude modulation (QAM) scheme.

The broadcast server 120 may transmit the source identification information and the address information capable of identifying the video and audio information together when transmitting the modulated video and audio information to the personal video recording apparatus 130. [ As the source identification information, source ID, locator, transport stream information, program number, and the like can be used. As the address capable of identifying the video and audio information, any of a Unicast Address, a Multicast Address, and a Broadcast Address can be used. In addition, a URL (Uniform Resource Locator), which generally includes a protocol, address and port information, can be used as an address capable of identifying the video and audio information.

Then, the broadcasting server 120 receives information on the recording result of the transmitted video and audio information from the personal recording apparatus 130. [ The broadcast server 120 provides information on the recording result received from the personal recording apparatus 130 to the video phone 110 using an ARS service, a text service, or the like.

For the above-described operation, the broadcasting server 120 includes a video communication receiving module 122, a broadcasting service module 124, and a modulation module.

The video communication receiving module 122 performs an operation to support a communication service with the video telephone 110 through the communication network 140. The broadcasting service module 124 transmits the video data to the personal recording apparatus 130, And the like.

The modulation module may be composed of various modulation modules according to a supported modulation scheme. In FIG. 1, an edge quadrature amplitude modulation (QAM) module 126 that provides video and audio information modulated by a quadrature amplitude modulation (QAM) scheme to a single receiver (a specific personal recording device) And an IP streamer module 128 that modulates voice information and provides it to a single receiver (a specific personal video recording device).

However, it will be appreciated that some or all of the video communication receiving module 122, the broadcasting service module 124, and the modulation module may be implemented in a device separate from the broadcasting server, rather than being provided in the broadcasting server. When implemented as separate devices, a communication protocol that enables exchange of information between each device should be defined.

When the recording request is received from the broadcasting server 120, the personal recording apparatus 130 transmits the recording availability to the broadcasting server 120 in consideration of the workload of the broadcasting apparatus. That is, the personal video recording apparatus 130 permits the broadcasting server 120 to record video and audio information provided from the broadcasting server 120 only when the user can record the video and audio information. Otherwise, the personal video recording apparatus 130 rejects the recording in response to the recording request from the broadcasting server 120. For example, if the general broadcast recording is already in progress, the personal recording apparatus 130 rejects the recording request because the general broadcast recording is in progress.

When the recording is rejected by the personal recording apparatus 130, the broadcasting server 120 reports to the video phone 110 that the recording is rejected by the personal recording apparatus 130. At this time, the broadcast server 120 may report a specific reason for recording being rejected (such as recording a general broadcast).

Also, the video phone 110 may check the reason for the recording rejection reported from the broadcasting server 120, and then perform an operation for eliminating the reason for the recording rejection. For example, if the recording is rejected because the broadcast server 120 is recording a general broadcast, the video phone 110 stops recording the general broadcast to the personal video recording apparatus 130, You can instruct to record the information.

If the recording apparatus 130 has accepted the recording, the personal video recording apparatus 130 receives the modulated video and audio information transmitted from the broadcasting server 120 through the channel indicated by the channel information provided in the recording request. Demodulates the received modulated video and audio information, and records the demodulated video and audio information on a built-in recording medium. As the recording medium, various types can be used depending on the type of the personal recording apparatus. A typical recording medium is a hard disk (HDD).

When the recording of the video and audio information transmitted from the broadcasting server 120 is completed, the personal recording apparatus 120 transmits the information on the recording result to the broadcasting server 120. The information on the recording result includes not only the recording success, but also information on the recording start time, the recording end time, the area of the recorded recording medium, and the like. Also, if the recording fails, the cause of the failed recording may be included. The cause of the failure of the recording may be a shortage of the recording medium, a demodulation error, or the like.

The video phone 110 transmits video and audio information obtained through the camera and the microphone or previously stored video and audio information to the broadcasting server 120 in step 218. [

The broadcast server 120 determines the personal video recording apparatus to which the video and audio information is to be transmitted according to the personal recording apparatus identifier transmitted from the video phone 110. The broadcasting server 120 transmits a recording request message to the determined personal recording apparatus 130 in step 220. [

When the recording request message is received from the broadcasting server 120, the personal recording apparatus 130 determines whether recording is possible by examining its work load. If the personal recording apparatus 130 determines that recording is possible, the personal recording apparatus 130 transmits a recording acknowledgment message to the broadcasting server 120 in step 222.

Although not shown in the figure, if the personal video recording apparatus 130 determines that recording is not possible, the personal recording apparatus 130 transmits a recording rejection message to the broadcasting server 120 to reject the recording. In this case, the broadcasting server 120 reports that the video phone 110 has been rejected by using the ARS service or the text service.

The video and audio information can be received from the video phone 110 even if the recording is rejected by the personal video recording apparatus 130. [ This is to transmit the received video and audio information to the personal video recording apparatus 130 when the personal recording apparatus 130 can record the video.

As described above, the video phone 110 can continue to receive the video and audio information even if the recording is rejected. That is, the video phone can determine whether the video and audio information is continuously received in the state in which the recording is rejected.

Upon receiving the recording acknowledgment message, the broadcasting server 120 modulates the video and audio information received from the video phone 110 according to a predetermined modulation scheme. In step 224, the modulated video and audio information is transmitted to the personal video recording apparatus 130.

The personal recording apparatus 130 demodulates the modulated video and audio information received from the broadcasting server 120 according to a predetermined demodulation method and records the demodulated video and audio information on a recording medium.

When the recording of the video and audio information is completed, the personal recording apparatus 130 transmits the information on the recording result to the broadcasting server 120 using a recording result reporting message.

The broadcast server 120 transmits the information on the recording result transmitted from the personal recording apparatus 130 to the video phone 110 using an ARS service, a text service, or the like.

FIG. 3 shows a control flow performed by a video telephone for video and audio recording according to an embodiment of the present invention.

Referring to FIG. 3, when a user inputs a key for requesting a video communication together with a unique number for calling an opposite terminal, the video telephone requests video communication with a counterpart terminal corresponding to the unique number in step 310. In the present invention, the counterpart terminal may be a broadcast server supporting a video communication service, wherein the unique number is information for identifying a video communication module supporting video communication in the broadcast server.

The video phone monitors in step 312 whether a video communication connection response corresponding to the video communication request is received from the broadcasting server. When the video phone receives a video communication connection response from the broadcasting server, the video telephone establishes a communication channel with the broadcasting server in step 314.

If the communication channel is established, the video phone transmits identification information of a personal video recording apparatus to record video and audio information to be transmitted in step 316. [ The identification information of the personal video recording equipment will be used to determine the personal video recording equipment to which the video and audio information received by the broadcast server will be transmitted.

In step 316, the video phone transmits video and audio information obtained through a user interface means such as a camera and a microphone or previously stored video and audio information to the broadcasting server.

The video phone determines in step 318 whether the transmission of the video and audio information is completed. The completion of the transmission of the video and audio information can be determined based on whether the video communication is terminated or the transmission of all the video and audio information to be transmitted is completed by the user's request. If the video phone determines that the transmission of the video and audio information is completed, the video phone proceeds to step 320 and releases the communication channel formed with the broadcasting server.

The video phone may receive a report from the broadcasting server informing that the recording has been rejected from the personal recording apparatus during transmission of the video and audio information. In this case, the video phone informs the user through the user interface that the recording has been rejected by the personal recording apparatus. However, the video phone can continue to transmit video and audio information even if it is reported that the recording is rejected. That is, the video phone can determine whether the video and audio information is transmitted in the state in which the recording is rejected.

The video phone monitors in step 322 whether information about the recording result corresponding to the video and audio information that has been transmitted is reported from the broadcasting server. This can be determined by whether information on the recording result is received through the ARS service and the text service.

When the information about the recording result is reported, the video phone informs the user of the information about the recorded recording result through the user interface in step 324. As a method of informing the user of the recording result, it is possible to display it in the form of a character or guide it by voice.

FIG. 4 illustrates a control flow performed by a broadcast server to record video and audio information according to an embodiment of the present invention.

Referring to FIG. 4, the broadcast server monitors whether a video communication connection request is received from the video telephone in step 410. FIG. When the video communication connection request is received from the video telephone, the broadcasting server determines whether it is possible to proceed with the current video communication in step 412. If the video communication is possible by the determination, the broadcasting server transmits a response message corresponding to the video communication connection request To the video telephone.

In step 414, the broadcast server forms a communication channel for video communication with the video phone. In step 416, the broadcast server receives the personal recording apparatus identification information for specifying the personal recording apparatus to record the video and audio information to be received in the future. Upon receiving the personal recording apparatus identification information, the broadcasting server branches to step 422 and transmits a message requesting recording to the personal recording apparatus designated by the personal recording apparatus identification information.

In step 416, the broadcasting server receives video and audio information transmitted from the video telephone. Upon receiving the video and audio information from the video telephone, the broadcasting server branches to step 418 and monitors whether the video and audio information is completely received from the video telephone.

If it is determined that the reception of the video and audio information from the video telephone is completed, the broadcasting server proceeds to step 420 and releases the communication channel formed with the video telephone.

In step 424, the broadcast server monitors whether the recording is permitted from the personal recording apparatus that requested the recording. If the recording approval is not received from the personal recording apparatus, the broadcast server repeatedly performs step 422 until the recording approval is made. The broadcast server reports to the video phone that the video recording has not been accepted using the ARS service, the text service, or the like. The broadcasting server decides whether to receive and store video and audio information in a state in which recording is rejected by an instruction from the video telephone.

The broadcast server modifies the video and audio information received from the video telephone through a predetermined modulation scheme in step 426. If the recording is permitted from the personal video recorder in step 424, The broadcast server delivers the modulated video and audio information to the personal recording equipment. As the modulation method, IP Unicast method and QAM method can be used. When the broadcasting server transmits the modulated video and audio information to the personal recording apparatus, the broadcasting server may transmit the source identification information and the unicast address information together. As the source identification information, source ID, locator, transport stream information, program number, and the like can be used. As the address capable of identifying the video / audio information, any of a Unicast Address, a Multicast Address, and a Broadcast Address can be used.

In step 430, the broadcast server transmits information about a recording result received from the personal recording apparatus to the video phone using an ARS service, a text service, or the like.

As a result, a recording result such as that the recording is already in progress and the recording is not performed because somebody is watching or the capacity of the recording medium is insufficient, may be transmitted to the user of the video phone.

FIG. 5 shows a control flow performed by an individual recording apparatus for recording video and audio information according to an embodiment of the present invention.

Referring to FIG. 5, in step 510, the personal video recording apparatus monitors whether a video recording request is received from a broadcasting server. When the recording request is received, the personal recording apparatus determines whether recording is possible in consideration of the workload of the recording apparatus and the remaining recording area of the recording medium in step 512. [ Upon the request for recording, the personal video recording apparatus may receive channel information for providing video and audio information from the broadcast server.

If the personal recording apparatus determines that recording is not possible by the determination, the personal recording apparatus proceeds to step 522 and transmits a recording rejection message in response to the recording request from the broadcasting server.

However, if the recording is enabled, the personal video recording apparatus proceeds to step 514 and transmits a recording acknowledgment message to the broadcasting server in response to the recording request from the broadcasting server.

The broadcasting server accepts the video recording and receives the video and audio information modulated from the broadcasting server in step 516. [ If the channel information is received at the time of the recording request from the broadcast server, the modulated video and audio information can be received through the channel specified by the channel information.

In step 518, the personal video recording apparatus determines whether recording of the modulated video and audio information received from the broadcast server is completed. If the recording is not completed, the personal video recording apparatus continuously demodulates the modulated video and audio information received from the broadcasting server and records the demodulated video and audio information on the recording medium.

Otherwise, if the recording is completed, the personal video recording apparatus reports information on the recording result to the broadcast server in step 520. [ The information on the recording result is reported to the broadcast server as the recording result even if the recording is not normally completed and the recording is interrupted due to a specific reason.
