Abstract

A method for providing an advertisement from a digital signage control apparatus to multiple mobile devices accessible to an access point installed in a digital signage terminal. The method may include determining whether the number of the mobile devices requesting the identical advertisement for a predetermined amount of time is greater than a threshold, and if the number of the mobile devices is greater than the threshold, transmitting the identical advertisement to the mobile devices through a multicast channel.

Claims

1. A method for providing an advertising service from a digital signage control apparatus to multiple mobile devices accessible to an access point installed in a digital signage terminal, comprising:

determining whether a number of mobile devices requesting an identical advertisement for a predetermined amount of time is greater than a threshold; and

if the number of the mobile devices is greater than the threshold, transmitting the identical advertisement to the mobile devices through a multicast channel.

2. The method of claim 1, wherein the transmitting of the identical advertisement comprises transmitting information for a multicast channel subscription to the mobile devices, and multicasting the identical advertisement through the mobile devices that have subscribed to the multicast channel.

3. A method for providing an advertising service from a digital signage control apparatus to multiple mobile devices accessible to an access point installed in a digital signage terminal, comprising:

determining whether n(X) is greater than N, wherein n(X) is a number of advertisements, and N is a number of all multicast channels;

if n(X) is greater than N, dividing whole bandwidth that is allocated to all the multicast channels by n(X) and allocating the divided bandwidth to each multicast channel; and

transmitting the advertisement through the multicast channels where the divided bandwidth each is allocated.

4. The method of claim 3, wherein the determining of whether n(X) is greater than N comprises:

counting Y, wherein Y is a number of advertisements simultaneously requested for a predetermined amount of time;

determining whether Y is greater than N; and

if Y is greater than N, determining whether n(X) is greater than N.

5. The method of claim 3, further comprising:

reducing advertising video quality after the dividing of the whole bandwidth.

6. The method of claim 5, wherein the reducing of the advertising video quality comprises changing a video encoding means.

7. The method of claim 5, wherein the reducing of the advertising video quality comprises selecting video sources that include a rate that is less than a predetermined value.

8. A digital signage control apparatus for providing an advertising service to multiple mobile devices accessible to an access point installed in a digital signage terminal, comprising:

a counter configured to count mobile devices requesting an identical advertisement for a predetermined amount of time; and

a multicast transmission unit configured to, if a number of the mobile devices counted by the counter is greater than a threshold, transmit the identical advertisement to the mobile devices through a multicast channel.

9. The digital signage control apparatus of claim 8, wherein the multicast transmission unit transmits information for a multicast channel subscription, and multicasts the advertisement to the mobile devices that have subscribed to the multicast channel.

10. The digital signage control apparatus of claim 8, further comprising:

a wireless resources management unit configured to, if n(X) is greater than N, divide whole bandwidth allocated to the multicast channel by n(X), wherein n(X) is a number of the advertisements to be transmitted through the multicast channel, and N is a number of all the multicast channels.

11. The digital signage control apparatus of claim 10, further comprising:

a video coding unit configured to, if the whole bandwidth is divided by the wireless resources management unit, reduce advertising video quality.

12. The digital signage control apparatus of claim 11, wherein the video coding unit changes a video encoding means.

13. The digital signage control apparatus of claim 11, wherein the video coding unit selects video sources that include a rate that is less than a predetermined value.
