This can be used to prevent data collision and to reproduce external data input from the communication IF unit having a high priority when a plurality of external data are received at the same time.

In the embodiment of the present invention, the priority is set in the order of the second communication IF unit 113-> third communication IF unit 115-> fourth communication IF unit 117. FIG. That is, the highest priority is set in the second communication IF unit 113, which may be understood that the second external data has the highest priority and the fourth external data has the lowest priority. .

The storage unit 120 may store various control programs, operating systems, software, user data, and the like required for driving the image output apparatus 100. In addition, the storage 120 may temporarily store the first external data received through the first communication IF unit 111. For example, when the first external data is transmitted in a download format, the first external data may be stored in the storage 120 and then reproduced.

The controller 130 controls the overall operation of the image output apparatus 100 using a control program, an operating system, and the like stored in the storage 120. In particular, when a plurality of external data are simultaneously received among the second to fourth external data, the controller 130 may select external data to be currently processed in consideration of a preset priority or a type of external data received.

In detail, the controller 130 may determine whether the second to fourth external data are received through the second to fourth communication IF units 113, 115, and 117. If it is determined that the second to fourth external data are received at the same time, the controller 130 may set a priority to the second to fourth external data. The controller 130 may set priorities to the second to fourth external data so as to correspond to the priorities set in the second to fourth communication IF units 113, 115, and 117. In addition, the controller 130 may control the signal processor 140 to process the external data in which the highest priority is set among the second to fourth external data.

If it is determined that the second to fourth external data are being received at the same time, the controller 130 may control the signal processor 140 to process the external data having the highest priority among the second to fourth external data. Can be.

In addition, when it is determined that the second to fourth external data are not received, the control unit 130 requests and receives and reproduces the first external data from the first external device through the first communication IF unit 111. Can work on In addition, in the reproduction mode, the signal processor 140 processes the first external data received through the first communication IF unit 111 as a reproducible signal under the control of the controller 130, and the signal processor 140 processes the signal. The processed first external data may be displayed through the display unit 145.

Meanwhile, in the present specification, the "playback mode for reproducing first external data" refers to requesting that the image output device according to an embodiment transmit the first external data to the first external device. Perform an operation, receiving the first external data according to the request, processing the received first external data as a playable signal, and displaying the signal-processed first external data through the display unit 145. Mode. In addition, that the reproduction mode for reproducing the first external data is 'activated' means that the image output apparatus according to an embodiment of the present invention is in the reproducing mode for reproducing the first external data. When the playback mode is 'disabled', it means that the video output apparatus according to the exemplary embodiment of the present invention is not in the playback mode for playing back the first external data.

As described above, when the second to fourth external data are not received, another screen may be temporarily displayed instead of a state in which no screen is displayed on the display unit 145.

In addition, when it is determined that at least one of the second to fourth external data is received while the first external data is processed as a reproducible signal and displayed on the display unit 145, the controller 130 controls the signal of the first external data. The process ends, and the reproduction mode of the first external data is deactivated. If at least one of the second to fourth external data is received, the controller 130 may determine the priority of the received external data. For example, when the third and fourth external data are received, the controller 130 may further include a third having a higher priority based on the priority set in the third and fourth communication IF units 115 and 117. The signal processor 140 may be controlled to process external data into a reproducible signal.

Table 1 below shows an example in which the controller 130 selects external data to be reproduced according to a reception state of external data.

reception
condition First outside
data 2nd outside
data Third outside
data 4th outside
data Play
External data First state ○ × × × First external data Second state × ○ ○ × Second external data Third state × × × ○ 4th external data 4th state × × ○ ○ Third external data 5th state × ○ ○ ○ Second external data

Referring to [Table 1], ○ means that external data is being received, and × means that external data is not being received. For example, in the first state, since the second external data to the fourth external data are not received, the controller 130 requests the first external device 10 to transmit the first external data. When the first external data is received from the first external device 10, the controller 130 controls the signal processor 140 to output the first external data. In this state, when the transition to the second state described later (that is, the second external data is provided from the second external device and the third external data is provided to the third external device), the control unit 130 is the first communication IF The unit 111 is controlled to no longer receive data from the first external device 10. The controller 130 controls the signal processor 140 to output second external data having priority. When at least one of the second external data and the fourth external data is being received, the controller 130 controls the first communication IF unit 111 to not receive content data from the first external device 10. . The controller 130 requests and receives the first external data from the first external device 10 only when the second external data to the fourth external data are not received at all, and outputs the received first external data. .

In the second state, since the second and third external data are received, the controller 130 selects the second external data having a high priority as external data to be reproduced.

Also, in the third state, since the fourth external data is received, the controller 130 may control the display unit 145 to display the fourth external data processed by the signal processor 140. While the fourth external data is displayed, the controller 130 continuously determines whether the second and third external data are received, the reception of the fourth external data is terminated, and the second and third external data are not received. Otherwise, the first communication IF unit 111 may be activated to receive the first external data. The controller 130 may control the signal processor 140 and the display unit 145 to signal-process and display the first external data.

The controller 130 may include a confirmation unit 131 and an information upload unit 133. The controller 130, the confirmation unit 131, and the information uploading unit 133 may be logically or physically divided or integrated into one.

When the reproduction mode of the first external data is activated, the confirmation unit 131 may check the reproduction related information while the first external data is processed and reproduced by the signal processing unit 140. The reproduction related information may be at least one of the first reproduction related information and the second reproduction related information which will be described below.

In detail, the identification unit 131 may check the time when the reproduction mode of the first external data is activated, and start counting from the identified time to count the total reproduction time of the first external data.

In addition, the checker 131 may further count the number of times that the first external data is repeatedly processed by the signal processor 140 or the number of times that the first external data is output to the display unit 145. For example, when the first external data is advertising content for 3 minutes and the first external data is processed for 9 minutes, the confirmation unit 131 may count the number of outputs three times.

The information uploading unit 133 transmits information on at least one of the total reproduction time and the number of outputs counted by the identification unit 131, that is, the first reproduction related information, through the network 50 to the first communication IF unit 111. The first communication IF unit 111 transmits the first reproduction related information to the first external device 10.

The information uploading unit 133 may periodically upload the first play related information or, if the play mode of the first external data is deactivated, upload the counted result until the deactivated information, that is, the first play related information. . Deactivation of the reproduction mode may mean that at least one of the second to fourth external data is received so that reproduction of the first external data is terminated and reception of the first external data is no longer performed.

Next, the second reproduction related information will be described. The verification unit 131 confirms a start time point (or start point at which playback is started) and the end time point (or point in time at which playback ends) when the first external data starts to be processed by the signal processor 140. Can be. In detail, the identification unit 131 may identify, as a start time, a time point when the reproduction mode of the first external data is activated or a time point at which the first external data starts to be processed by the signal processor 140. In addition, the identification unit 131 may identify a time point when the reproduction mode of the first external data is deactivated or a time point when signal processing of the first external data ends.

The first external device 10 uses the received first reproduction related information and / or the second reproduction related information so that the first external data can be continuously reproduced when the first external data is reproduced next in the image output apparatus 100. Can be determined. If the image output apparatus 100 requests to transmit the first external data again, the first external device 10 transmits the first external data determined to be reproduced next.

The information uploading unit 133 uploads the information about the start time and the end time confirmed by the checking unit 131, that is, the second playback related information, to the first communication IF unit 111 through the network 50. The first communication IF unit 111 may transmit the second reproduction related information to the first external device 10. If the second external data is received while the first external data is processed and provided to the user, the information uploading unit 133 may upload the second reproduction related information.

The signal processor 140 may process one of the external data being received as a playable signal under the control of the controller 130. For example, when the second external data is being received through the second communication IF unit 113, the signal processor 140 may process the second external data as a reproducible signal.

The display unit 145 may display data provided from the signal processor 140 so that a user can view it. The display unit 145 may be a device included in the image output device 100 or provided separately.

If the second external data is received while the first external data is processed and provided to the user, the controller ends the processing of the first external data and provides information about the start time and the end time to the external device. And controlling the first communication interface unit to transmit the data to the first communication interface. Receiving data through the plurality of communication interface units;
If it is determined that the second external data is not received, reproducing the first external data; And
And when the second external data is received while reproducing the first external data, ending the reproduction of the first external data and reproducing the second external data.
If it is determined that the second external data is not received, the step of reproducing the first external data,
Requesting the first external data from an external device capable of providing the first external data; And
Receiving and playing the first external data; and outputting the first external data. The method of claim 10,
Receiving third external data; And
And reproducing external data having a higher priority among the second external data and the third external data. The method of claim 10,
Counting a total reproduction time at which the first external data is reproduced; And
And transmitting the counted total reproduction time to an external device that provides the first external data. delete The method of claim 12,
The transmitting may include transmitting the counted total reproduction time to the external device periodically or when reproduction of the first external data ends. The method of claim 12,
The transmitting may include transmitting the counted playback time to the external device when the second external data is received while the first external data is reproduced and provided to the user. The method of claim 10,
Checking a start time and an end time at which the first external data starts to be reproduced; And
And transmitting the identified start time point and the end time point information to an external device that provides the first external data. 17. The method of claim 16,
The transmitting step,
When the second external data is received while reproducing and outputting the first external data to a user, ending the reproduction of the first external data and transmitting the start time and the end time information to the external device. Video output method characterized in that. The method of claim 10,
Counting the total reproduction time at which the first external data is reproduced or checking a start time and an end time at which the first external data starts to be reproduced;
Transmitting the counted total reproduction time or the start time and the end time to an external device providing the first external data;
Determining, by the external device, first external data to be played next with reference to the entire reproduction time or the start time and the end time; And
When the external device receives a request for transmission of first external data from the device that has transmitted the entire reproduction time or the start time and the end time, transmitting the first external data determined to be played back to the device next time; Image output method further comprises. delete
