FIG. 2 is a schematic diagram of a multimedia device and a control server according to an exemplary embodiment of the present invention. Referring to FIG. Hereinafter, a multimedia device and a control server according to an embodiment of the present invention will be schematically described with reference to FIG.

2, a control server 200 according to an embodiment of the present invention, a first network TV 201, a second network TV 202, a third network TV 203, (210) are connected by wired / wireless communication. For example, an IP (Internet Protocol) network.

At this time, the control server 200 periodically polls the network TVs and is designed to collect information about the channel currently being viewed by each network TV.

Meanwhile, the network TV 200 may be designed to collect channel information of all network TVs, or may be designed to restrictively collect only channel information of network TVs within a certain range. This will be described later in detail with reference to FIG.

3 is a diagram illustrating an IP address scheme of a multimedia device according to an exemplary embodiment of the present invention. Hereinafter, a method of performing a limited range of channel browsing using an IP address allocated to each multimedia device according to an embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 3, each of the network TVs connected to the control server is assigned a unique IP address. The IP address takes a form in which, for example, four numbers from 0 to 255 are distinguished by a period (.). If the digits corresponding to a certain number of digits are the same and the digits corresponding to the remaining digits belong to a certain range, it can be assumed that the IP address belongs to a specific unit area. However, this is an embodiment, and it is also possible to estimate a certain area with an IP address using another method.

Therefore, the control server can retrieve the channel information only for the network TVs located in the predetermined area, using the IP unique address of the network TVs. This will be described later in detail with reference to FIGS. 5 to 9.

Alternatively, it may be designed to obtain a more limited channel browsing result only for network TVs having IP addresses directly input by the user. This will be described later in detail with reference to FIGS. 10 to 12.

4 is a diagram for explaining a control server for collecting channel information of each multimedia device according to an embodiment of the present invention. Hereinafter, referring to FIG. 4, a method of selectively collecting only non-overlapping channel information by skipping over overlapping channel information of each multimedia device according to an exemplary embodiment of the present invention will be described.

4, the control server 460 scans all network TVs connected to the network or network TVs 410, 420, 430, 440, and 450 belonging to a limited range, And collects all of the broadcast channel information.

However, since both the first network TV 410 and the second network TV 420 are viewing the A channel, it is sufficient to acquire the capture screen for the A channel only once. Therefore, it is possible to reduce waste of resources and time due to overlapping capturing.

Further, the control server 460 also collects a capture screen for the B channel of the third network TV 430 and a capture screen for the C channel of the fourth network TV 440. Also, although not shown in detail in FIG. 4, the fifth network TV 450 corresponds to a case in which a personal broadcasting is outputted rather than a channel of a general broadcasting station. Therefore, there is an advantage that a personal broadcasting which is being broadcast through a cam other than a general broadcasting station can be included in the channel browsing target.

That is, according to the embodiment of the present invention described above, a separate control server 460 is provided to perform screen capturing for a plurality of TVs. In addition, it is designed to skip the same channel, and the captured image is transmitted to the control server 460 together with other metadata.

The control server 460 communicates with the network TV every predetermined time to continuously update the capture screen for the channel being viewed on each network TV. Using the IP address shown in FIG. 3, only the channel information for a certain area can be selectively collected, or only the channel information for a specific network TV registered by the user can be collected.

FIG. 5 is a flowchart sequentially illustrating operations of a multimedia device and a control server according to an exemplary embodiment of the present invention in order of time flow. Hereinafter, with reference to FIG. 5, an entire process of collecting only channel information for multimedia devices located in a specific area will be described. However, the steps shown in FIG. 5 are intended to illustrate an embodiment of the present invention, and the scope of rights of the present invention should in principle be determined by the claims.

As shown in FIG. 5, the control server 500 according to an exemplary embodiment of the present invention requests channel information from an arbitrary first network TV 510 (S501). Also, the control server 500 requests channel information for another network TV 520 belonging to the same first region as the first network. The channel information may be, for example, broadcasting station information, channel number information, or captured image data of a screen currently being output.

Further, the first network TV 510 transmits the channel information of the currently watched channel to the control server 500 as a response to the step S501 (S502).

In addition, the control server 500 transmits data indicative of the channel selection status currently being watched by the multimedia devices (510, 520, etc.) located in the first area to each of the network TVs 510, 520 (S503 ).

The first network TV 510 is designed to display the selected state of the first channel and the selected state of the second channel on the screen based on the received data (S504). The channel browsing screen outputted in step S504 will be described later in detail with reference to FIG. 6 to FIG.

FIG. 6 is a diagram illustrating a first embodiment of a screen in which the multimedia device shown in FIG. 5 outputs a channel browsing result. Hereinafter, referring to FIG. 6, a method of outputting a capture screen of a different size according to a channel browsing result of a multimedia device according to an embodiment of the present invention will be described.

As shown in FIG. 6, the network TV 610 performing the steps of FIG. 5 outputs a channel browsing result to a certain area 620 of the entire screen. In particular, it is impossible to exclude the possibility that there are many network TVs that are watching the same channel among the network TVs belonging to the same area range.

Accordingly, based on the data received in step S503, the network TV 610 distinguishes the first channel that is the most viewed among the multimedia devices located in the same first area and the second channel that is the least viewed.

6, the network TV 610 is designed to display the selected state of the first channel at a first size and display the selected state of the second channel at a second size . However, by setting the second size to be smaller than the first size, the user can more clearly confirm the channel that is being viewed more among the network TVs in the same area. For example, the size can be designed to be adjusted in proportion to the number of network TVs being watched. The area of each channel shown in FIG. 6 may correspond to the corresponding capture screen. As described above with reference to FIG. 4, the capture screen of the same channel is omitted in the scanning process.

FIG. 7 is a diagram illustrating a second embodiment of a screen in which the multimedia device shown in FIG. 5 outputs a channel browsing result. Hereinafter, referring to FIG. 7, a method of outputting a capture screen of a different contrast ratio according to a channel browsing result of a multimedia device according to an embodiment of the present invention will be described.

As shown in FIG. 7, the network TV 710 performing the steps of FIG. 5 outputs a channel browsing result to a predetermined area 720 of the entire screen. In particular, it is impossible to exclude the possibility that there are many network TVs that are watching the same channel among the network TVs belonging to the same area range.

Thus, based on the data received in step S503, the network TV 710 distinguishes the first and second least viewed channels from among the multimedia devices located within the same first area.

7, the network TV 710 is designed to display the selected state of the first channel at a first contrast ratio and display the selected state of the second channel at a second contrast ratio . However, by setting the second contrast ratio lower than the first contrast ratio, the user can more clearly confirm the channel that is being watched more among the network TVs in the same area. For example, it is possible to design the contrast ratio to be adjusted in proportion to the number of network TVs being watched. The area of each channel shown in FIG. 7 may correspond to the corresponding capture screen, and as described above in FIG. 4, the capture screen of the same channel is omitted in the scanning process.

In addition, FIG. 6 shows the preferences of the channels differently according to the sizes of the captured screens, whereas FIG. 7 shows the preferences of the channels differently based on only the contrast ratio of the captured screens. In addition, according to another embodiment of the present invention, it is possible to combine FIG. 6 and FIG. 7 so as to emphasize and display a currently viewed channel using both the size and the contrast ratio.

FIG. 8 is a diagram illustrating a third embodiment of a screen in which the multimedia device shown in FIG. 5 outputs a channel browsing result. Hereinafter, a method of outputting a pay channel and a free channel in accordance with a channel browsing result according to an embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 8, the network TV 810 performing the steps of FIG. 5 outputs a channel browsing result to a predetermined area 820 of the entire screen. Particularly, as a result of the channel browsing, there can be both a pay channel in which pay contents are output and a free channel in which free contents are being output. At this time, if the user accesses an arbitrary channel, an unexpected charging problem occurs. In addition, for a pay channel that is consumed in a network TV in the same area, there is a high possibility that a user may select with curiosity, so a GUI design guiding this is needed.

Therefore, based on the data received in step S503, the network TV 810 distinguishes the pay channel and the free channel from the channels being viewed by the multimedia devices located in the same first area.

8, the network TV 810 displays the capture screens 830 and 840 of the pay channel in a highlighted form, and displays the captured screens of the remaining free channels in a non-highlighted form . Therefore, a user who uses the network TV 810 has a high possibility of selecting a pay channel which is currently being watched in a network TV in the same area, and as a new revenue source in terms of a broadcasting station.

FIG. 9 is a diagram illustrating a fourth embodiment of a screen in which the multimedia device shown in FIG. 5 outputs a channel browsing result. Hereinafter, with reference to FIG. 9, another method of outputting a pay channel and a free channel separately according to a channel browsing result of a multimedia device according to an embodiment of the present invention will be described.

As shown in FIG. 9, the network TV 910 performing the steps of FIG. 5 outputs a channel browsing result to a predetermined area 920 of the entire screen. Particularly, as a result of the channel browsing, there can be both a pay channel in which pay contents are output and a free channel in which free contents are being output. At this time, if the user accesses an arbitrary channel, an unexpected charging problem occurs. In addition, for a pay channel that is consumed in a network TV in the same area, there is a high possibility that a user may select with curiosity, so a GUI design guiding this is needed.

Thus, based on the data received in step S503, the network TV 910 distinguishes between a pay channel and a free channel from the channels being viewed by the multimedia devices located in the same first area.

9, the network TV 910 displays a captured screen of the separated pay channel in the first area 930 of the screen, and a captured screen of the separated free channel is displayed And to display in a second area of the screen.

That is, as shown in FIG. 9, by designing the capture area of the pay channel and the capture area of the free channel to be completely distinguished from each other, the problem of time loss and billing due to the unwanted pay channel connection can be solved.
