2 is a block diagram for explaining a configuration of a digital information recording apparatus according to an embodiment of the present invention.

3 is a view showing an example of a recording medium structure for recording data information according to an embodiment of the present invention, and FIG. 4 is a method for updating and deleting data information according to an embodiment of the present invention. It is a figure for demonstrating.

5 is a diagram showing an example of a recording medium structure for recording data information according to another embodiment of the present invention.

Specifically, as shown in FIG. 2, the digital information recording apparatus 100 according to an embodiment of the present invention includes a transceiver 110, a data update processor 120, a data recorder 130, a record controller 140, and a list. Generator 150.

The transceiver 110 receives at least one time information of the display completion time and the display end time of the network terminal 200, and transmits the identification information of the network terminal 200 and the information of the received display completion time or the display information time. The data update processor 120 transmits the data.

For reference, the identification information of the network terminal 200 may be an identification code uniquely assigned to each network terminal, and each network terminal 200 may be distinguished through the identification information.

The data update processor 120 confirms identification information of the network terminal 200 with respect to the display completion time or the display end time currently received, and checks the data information for each network terminal 200 stored through the data recorder 130. Data information of the network terminal 200 having the same identification information as the extracted identification information is extracted. The data update processor 120 updates and stores the currently received display completion time or display end time in the corresponding data information.

As such, the process of updating the display completion time or the display end time currently received by the data update processor 120 will be described in detail with reference to FIGS. 3 to 5.

The data recorder 130 stores data information for each network terminal 200 in a recording medium. In this case, the data information of the network terminal 200 includes a data display completion time and a data display end time, and further includes information on data requested by the corresponding network terminal 200 and access information about the network terminal 200. can do. For reference, the recording medium according to an embodiment of the present invention may be in the form of a database.

Meanwhile, the data recorder 130 according to an embodiment of the present invention stores data information for each network terminal 200 in a recording medium having a structure as shown in FIGS. 3 to 5, and the data information is stored in each network terminal 200. A display completion time and a display end time matched with the identification information.

Specifically, FIGS. 3 and 4 show that the recording medium according to the embodiment of the present invention has a structure including at least three fields. At this time, the order of the information stored in each field may be changed.

As illustrated in FIG. 3, the data recorder 130 may include the first to third fields P312 and P313 for identification information of the plurality of network terminals 200 (referred to as IDs in FIGS. 3 to 5). , P314, to store data information.

For example, in FIG. 3, the display completion time is stored in the first field P312 and the second field P313, and the display end time is stored in the third field P314.

In detail, the first field P312 stores a time when the corresponding network terminal 200 first receives data and completes display after connecting to the data providing apparatus 300. As such, the display completion time stored in the first field P312 is maintained without being updated, and the corresponding network terminal 200 is connected to the data providing device 300 through the display completion time recorded in the first field P312. After that, the first data display completion time can be checked. That is, as shown in FIG. 3, the display completion time stored in the first field P312 may be referred to as 'first data display completion time'.

The data display completion time is stored for each network terminal 200 in the second field P313, and the display completion time stored in the second field P313 is received from the data providing device 300 by the network terminal 200. It is updated each time the completed data is displayed on the screen. The display completion time of the most recently received data from the data providing apparatus 300 by the corresponding network terminal 200 may be confirmed through the display completion time stored in the second field P313. That is, as shown in FIG. 3, the display completion time stored in the second field P313 may be referred to as 'recent data display completion time'.

In addition, the data end time is stored for each network terminal 200 in the third field P314, and the display end time stored in the third field P314 ends the display of the data received from the data providing apparatus by the network terminal. It is updated every time. Through the display end time stored in the third field P314, the most recent time when the corresponding network terminal 200 finishes displaying any one of the data already displayed is confirmed. That is, as shown in FIG. 3, the display end time stored in the third field P314 may be referred to as a 'recent data display end time'.

On the other hand, the data update processor 120 according to an embodiment of the present invention transmits to the data recorder 130 so that newly received display completion or display end time is stored in accordance with the identification information of the network terminal 200.

Specifically, as shown in FIG. 4, the data recorder 130 updates and records the previously stored display completion or type time to the currently received display completion or end time under the control of the data update processor 120.

For example, P401 of FIG. 4 shows that the data recorder 130 updates the latest data display completion time on the recording medium under the control of the data update processor 120. Specifically, in the case of the network terminal 200 having the ID 'a001', while the previous data display completion time is recorded as 10:27:05, the newly received display completion time is updated to 10:28:02 and recorded. It is shown.

In addition, P402 of FIG. 4 shows that the data recorder 130 updates the latest data display end time on the recording medium under the control of the update processor 120. Specifically, in the case of the network terminal having the ID 'a003', the previous data display end time is recorded as 10:29:58, and the newly received display end time is 10:31:26 to indicate that it is recorded. It was.

In addition, P403 of FIG. 4 shows that the data recorder 130 updates the latest data display end time on the recording medium under the control of the update processor 120. Specifically, in the case of the network terminal whose ID is 'b654', the previous data display completion time is recorded as 10:29:54, and the newly received display completion time is 10: 31: 29, indicating that it is recorded. It was.

2 again, the recording controller 140 records or stores digital information for the network terminal 200 by deleting or maintaining data information for each network terminal 200 stored through the data recorder 130 according to a predetermined control criterion. To control.

At this time, the recording controller 140 deletes the recording of the data information for the network terminal 200 that is determined to be terminated in connection with the data providing apparatus 130 according to a preset deletion criterion.

Specifically, the recording controller 140 checks the display completion time and the display end time of the data information for each network terminal 200 stored in the recording medium through the data recorder 130, so that the latest display end time is the latest display completion. The data information record of the network terminal 200 after the preset reference time has elapsed after the latest display end time among the network terminals 200 after the time is deleted.

In this way, it is possible to check whether the network terminals 200 connected to the data providing device 300 are connected or not, and manage the limited storage space efficiently.

For example, in FIG. 4, the network terminals 200 having IDs 'a003' and 'b654' show that the latest data display end time is after the latest data completion time.

At this time, the recording controller 140 displays 10:31:26 which is the display end time of the network terminal 200 having the ID 'a003' shown in P402 of FIG. 4 and the current time (that is, the time when determining whether to end). Compare For reference, FIG. 4 shows that the reference time elapses without updating the latest data display completion time after the latest data display end time recorded for the network terminal 200 having the ID 'a003'. Therefore, the recording controller 140 deletes the recording of the data information of the network terminal 200 whose ID is 'a003'.

Then, the recording controller 140 displays the current time (that is, the time at which it is determined whether to end) from 10:31:29 which is the display end time of the network terminal 200 whose ID shown in P403 of FIG. 4 is 'b654'. Compare For reference, FIG. 4 shows that the reference time has not passed since the last data display end time recorded for the network terminal 200 having the ID 'b654'. Accordingly, the record controller 140 does not delete the record of the data information of the network terminal 200 whose ID is 'b654'.

Meanwhile, the recording controller 140 according to an embodiment of the present invention determines whether the connection of the network terminal 200 to the data providing apparatus 300 is terminated at predetermined intervals (for example, at intervals of 5 seconds). After the determination, the information on the determined connection maintenance or connection termination may be recorded to be included in the data information.

At this time, the data recorder 130 according to another embodiment of the present invention stores the data information of the network terminal 200 in a recording medium having at least four fields as shown in FIG. For reference, the order of the information stored in each field may be changed.

Specifically, in FIG. 5, the network terminal includes a fourth field including the first to third fields described with reference to FIGS. 3 and 4, and further including a fourth field in which the connection termination information of the network terminal 200 is stored. It is shown that the data information per 200 is stored.

At this time, the recording controller 140 checks the display completion time and the display end time of the data information for each network terminal 200 stored in the recording medium through the data recorder 130, so that the latest display end time is the latest display completion time. After that, the data information of the network terminal 200 is extracted.

The recording controller 140 determines whether to terminate the connection, based on whether a predetermined reference time has elapsed from the latest display end time for the extracted network terminal 200.

At this time, the recording controller 140 determines that the connection with the data providing apparatus 300 is terminated with respect to the network terminal 200 in which the reference time has elapsed from the latest display end time, and provides the end information in the fourth field. Record it. On the other hand, the recording controller 140 assumes that the connection with the data providing device 300 is still maintained for the network terminal 200 in which the reference time has not elapsed since the last display end time. To continue.

For example, P501 of FIG. 5 shows that the latest data display completion time of the network terminal 200 whose ID is 'a001' is updated after the latest data display end time. Accordingly, the recording controller 140 processes the maintenance information to be maintained in the fourth field P135 for the network terminal 200 whose ID is 'a001'.

In addition, P502 and P503 of FIG. 5 indicate that the last data display end time of the network terminal 200 having IDs 'a003' and 'b654' is after the latest data completion time, respectively.

Specifically, in FIG. 5, when the current controller operating time for determining whether the recording controller 140 ends is 10:31:32, the last data ending time of the network terminal 200 whose ID is 'a003' is 10: It is shown that after 31:26 the preset reference time (for example, 5 seconds) has elapsed. Therefore, the recording controller 140 processes the end information indicating the end of the connection to be recorded in the fourth field for the network terminal 200 of 'a003'.

In addition, in FIG. 5, when the current controller operating time is 10:31:32 to determine whether the recording controller 140 ends, 10:31 which is the last data ending time of the network terminal 200 whose ID is 'b654' is 10:31. After: 29, the preset reference time (for example, 5 seconds) did not pass. Thus, the recording controller 140 continues the maintenance information previously recorded in the fourth field for the network terminal 200 of 'b654'.

On the other hand, the recording controller 140 according to an embodiment of the present invention may delete the data information recording for the network terminal 200 is terminated the connection with the data providing apparatus 300 at each predetermined erase period.

Specifically, the recording controller 140 checks the data information for each network terminal 200 recorded through the data recorder 130 at a predetermined erase period (for example, 10 minutes), so that the display end time is the display completion time. After that, the data information of the network terminal 200 after the preset reference time elapses after the recorded display end time is deleted.

Alternatively, the recording controller 140 checks the fourth field of the recording medium described with reference to FIG. 5 at each preset deletion period, extracts the network terminal 200 having the termination information recorded in the fourth field, and then satisfies a predetermined condition. The data information records of the network terminals 200 can be collectively deleted.

For example, P502 of FIG. 5 shows that a predetermined reference time (for example, 5 seconds) has elapsed since the last data display end time of the network terminal 200 having the ID 'a003'. Accordingly, it is shown that the termination information is recorded in the fourth field of the network terminal 200 having the ID 'a003'. At this time, the recording controller 140 checks the termination information of the fourth field of the network terminal 200 whose ID is 'a003' at the time of the determination of deletion according to a preset deletion period (for example, 10 minutes) and records the data information. Delete it.

In addition, P503 of FIG. 5 shows that a predetermined reference time (indicated as 'first period' in FIG. 5) has not elapsed since the last data end time of the network terminal 200 having the ID 'b654'. Thus, the recording controller 140 continues the maintenance information previously recorded in the fourth field for the network terminal 200 of 'b654'. At this time, the recording controller 140 checks the maintenance information of the fourth field of the network terminal 200 whose ID is 'b654' at the time of the determination of deletion according to a preset deletion period (for example, 10 minutes) and records the data information. Do not delete it.

3, the list generator 150 generates data information for each network terminal recorded through the data recorder 130 in a list form.

At this time, the list generator 150 may generate a new data information list after the data information of the network terminal 200 which has been terminated in connection with the data providing apparatus 300 is deleted under the control of the recording controller 140. In addition, the list generator 150 may obtain data information for each network terminal 200 through the data recorder 130 at predetermined intervals and generate a list.

For reference, the list generator 150 may sort the data information of each network terminal 200 based on the first data display completion time based on the first field described with reference to FIGS. 3 to 5.

In addition, the list generator 150 according to an embodiment of the present invention may receive a request for the generated list through the transceiver 110, and the device or terminal (eg, a data providing device) requesting the list. , A network terminal and a specific terminal requesting the list, etc.).

Meanwhile, components shown in FIGS. 1 and 2 according to an embodiment of the present invention mean software components or hardware components such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC), and have a predetermined role. Perform them.

However, 'components' are not meant to be limited to software or hardware, and each component may be configured to be in an addressable storage medium or may be configured to reproduce one or more processors.
