Description

{ADVERTISEMENT TRANSMISSION SYSTEM}

The present invention relates to an advertisement transmission system, and more specifically, to an advertisement transmission system in which a plurality of set-top boxes transmitting advertisement content to a plurality of display devices are improved to mutually synchronize the running times of the advertisement content.

Advertising content can be produced in various ways for visual and audio advertising, and can be understood as, for example, a digital work including display information or display information and audio information.

Advertising content can be displayed on a display device by being transmitted to a display device installed in a place for advertising. At this time, the display device can be a kiosk or a flat panel display device dedicated to advertising.

Advertising content can be provided from an advertising server to a set-top box via a network. To this end, the advertising server stores a plurality of advertising contents to be provided to the set-top box, and each advertising content can include schedule information for driving for transmission. The set-top box can be configured to drive the advertising contents provided from the advertising server according to a predetermined schedule and transmit them to a display device.

The set-top box and display device may be configured as a single set or configured separately. The display device may be installed according to the location where the advertising content is to be displayed. A kiosk can be considered an example in which the set-top box and display device are manufactured as one unit.

When the same advertising content is scheduled to be displayed simultaneously on multiple display devices distributed in multiple locations, multiple set-top boxes must drive the same advertising content at the same time and transmit it to the display devices simultaneously, and thus the display devices in multiple locations can display the corresponding advertising content at the same time.

However, the times at which advertising content is played on multiple set-top boxes may be affected by issues with the advertising server, set-top boxes, or other issues, and the times at which advertising content is broadcast on multiple set-top boxes may differ from each other.

As a result, it is difficult to expect that advertising content scheduled to run simultaneously will run and be transmitted simultaneously on multiple set-top boxes or displayed on multiple display devices at the same time for the above reasons.

In this case, there is a problem that the advertising effect through the display of advertising content may be reduced and the reliability of the advertising transmission system may be lowered.

An object of the present invention is to provide an advertisement transmission system capable of simultaneously driving advertisement contents scheduled to be displayed on multiple display devices at the same time from multiple set-top boxes and transmitting them to multiple display devices.

Another object of the present invention is to provide an advertisement transmission system capable of simultaneously displaying advertisement content on a plurality of display devices by mutually synchronizing the operating times of a plurality of set-top boxes transmitting advertisement content.

The advertisement transmission system of the present invention is characterized by including: an advertisement server providing advertisement contents; and a plurality of set-top boxes storing the advertisement contents, driving and transmitting advertisement contents to be displayed at the same time, and calling the advertisement server at the time of driving the advertisement contents.

The above advertisement server detects an error in the server time of each set-top box by using a server synchronization judgment range set based on an average of server times corresponding to calls of the plurality of set-top boxes; determines the synchronization type as set-top box-specific synchronization or server synchronization depending on whether the maximum deviation of the server times corresponds to the server synchronization judgment range; if the synchronization type corresponds to the set-top box-specific synchronization, it generates offset values corresponding to a difference between the server times of some set-top boxes and the average, and provides the offset values to some set-top boxes; and, if the synchronization type corresponds to the server synchronization, it is preferable that all set-top boxes provide server synchronization information for controlling the driving of the next advertisement content in the same manner.

And, each set-top box, when receiving the offset value, preferably changes the operating time of the next advertising content by applying the offset value; and when receiving the server synchronization information, preferably controls the operating of the next advertising content in a method corresponding to the server synchronization information.

The present invention has an advantage in that the running times of advertising contents running at the same time on a plurality of set-top boxes can be mutually synchronized for transmission to display devices by controlling the running times of advertising contents for each set-top box by determining the type of synchronization according to errors in the running times of advertising contents running at the same time on a plurality of set-top boxes, or by controlling the running of advertising contents of all set-top boxes from an advertising server.

Due to the above advantages, the present invention can obtain an improved advertising effect since advertising content can be displayed at the same time on multiple display devices, and can obtain the effect of improving the reliability of the advertising transmission system.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. The terms used in this specification and the patent claims should not be interpreted as being limited to their usual or dictionary meanings, but should be interpreted as meanings and concepts that are consistent with the technical aspects of the present invention.

The embodiments described in this specification and the configurations illustrated in the drawings are preferred embodiments of the present invention, and do not represent all of the technical ideas of the present invention, so there may be various equivalents and modified examples that can replace them at the time of filing this application.

Referring to FIG. 1, the advertisement transmission system of the present invention can be implemented to include an advertisement server (10), a plurality of set-top boxes (30a, 30b, 30c), and a plurality of display devices (40a, 40b, 40c).

An advertisement server (10) is configured to store advertisement content and provide the advertisement content to a plurality of set-top boxes (30a, 30b, 30c) through mutual communication over a network, and the plurality of set-top boxes (30a, 30b, 30c) are configured to transmit the advertisement content by driving it, and the plurality of display devices (40a, 40b, 40c) are configured to display the advertisement content transmitted from the plurality of set-top boxes (30a, 30b, 30c).

Here, the network can be understood as a normal Internet network or a dedicated network that allows two-way communication.

And, the plurality of set-top boxes (30a, 30b, 30c) and the plurality of display devices (30a, 30b, 30c) can be configured to correspond one-to-one, and can be configured as a single set, such as a kiosk used for advertising or sales, or can be configured separately at separate locations. The plurality of display devices (30a, 30b, 30c) can visually display advertising content transmitted from the set-top boxes (30a, 30b, 30c) corresponding to them. If necessary, the display devices (40a, 40b, 40c) can be configured to have an audio output function.

The detailed configuration of the advertisement server (10) and the plurality of set-top boxes (30a, 30b, 30c) of Fig. 1 is explained with reference to Fig. 2. For convenience of explanation, the display devices may be indicated as "40a, 40b, 40c" of Fig. 1 when necessary, but are collectively indicated as "40" of Fig. 2, and the set-top boxes may be indicated as "30a, 30b, 30c" of Fig. 1 when necessary, but are collectively indicated as "30" of Fig. 2.

First, the advertisement server (10) is configured to provide advertisement content to set-top boxes (30), and may be configured to control mutual synchronization of the driving times for driving advertisement content in the set-top boxes (30) in order to transmit the advertisement content to the display device (40) at the same time.

First, in order to provide advertising content, the advertising server (10) may include an advertising provision unit (12) that stores advertising content.

The advertisement providing unit (12) is configured to store a plurality of advertisement contents produced for display on a display device, manage schedule information for displaying the advertisement contents on the display device, and provide the advertisement contents to set-top boxes (30) set as destinations on a network. The advertisement contents may be provided together with the schedule information, but for the convenience of explaining the present invention, a detailed description of the schedule information is omitted.

In response to this, the set-top boxes (30) may be configured to store advertising contents provided by the advertising provision unit (12) of the advertising server (10), and to drive advertising contents to be displayed at the same time and transmit them to the display device (40). To this end, each of the set-top boxes (30) may include an advertising transmission unit (32) and an advertising storage unit (38).

The advertisement transmission unit (32) receives advertisement content provided by the advertisement provision unit (12) of the advertisement server (10), transmits it to the advertisement storage unit (38) for storage, and is configured to operate the advertisement content stored in the advertisement storage unit (38) according to a schedule and transmit it to the display device (40).

The advertisement storage unit (38) can store advertisement contents in the form of a queue, for example, and AD1, AD2, and ADn in Fig. 2 can be understood as indicating advertisement contents in the form of a queue.

In order to mutually synchronize the operating times of advertising contents to be transmitted at the same time of set-top boxes (30), the advertising server (10) may include a synchronization control unit (14), and the set-top boxes (30) may include a synchronization player (33). The synchronization control unit (14) and the synchronization player (33) may communicate with each other and perform operations necessary for mutual synchronization.

For example, the synchronization player (33) of the set-top boxes (30) can drive the advertisement content to be displayed at the same time from the advertisement transmission unit (32) and can be configured to call the synchronization control unit (14) of the advertisement server (10) at the time of driving the advertisement content. At this time, it can be understood that the synchronization player (33) driving the advertisement content includes controlling the driving of the advertisement content from the advertisement transmission unit (32).

The synchronization control unit (14) of the advertisement server (10) can generate server times corresponding to the call times of the synchronization player (33) of the set-top boxes (30), i.e., the running times of the advertisement content. At this time, the server times can be generated using absolute time that can be used to control synchronization in the advertisement server (10) or can be generated using arbitrary time information that indicates the difference between the server times.

Meanwhile, the advertisement server (10) may include an error detection unit (15), a jump control unit (16), and a reset control unit (17), and the set-top boxes (30) may each include an offset control unit (35) and a pause control unit (36).

The advertising server (10) and set-top boxes (30) configured as in Fig. 2 can determine the synchronization type as in Fig. 3 and perform operations for synchronization by set-top box and server synchronization.

Before explaining the operation of the advertisement server (10) and set-top boxes (30) with reference to FIGS. 2 and 3, the operating times of the set-top boxes (30), the server times of the advertisement server (10), the averages and deviations of the server times, the allowable error range, and the server synchronization judgment range are first explained with reference to FIG. 4.

The operating time of each set-top box (30) that drives the advertising content by the synchronization player (33) may vary depending on the advertising server (10), the set-top box (30), or other issues. And, the above-mentioned influence may act differently for each set-top box (30). Therefore, the operating times of the set-top boxes (30) of the advertising content scheduled to be driven at the same time may vary from each other, and as a result, the times at which the advertising content is transmitted to the display devices (40) may vary from each set-top box (30).

That is, the operating times of the set-top boxes (30) of the advertising contents scheduled to be operated at the same time can be formed at different times, such as D1, D2, and D3 of Fig. 4. When the synchronization player (33) of the set-top boxes (30) calls the advertising server (10) at the above-mentioned operating times D1, D2, and D3, the synchronization control unit (14) of the advertising server (10) can generate server times T1, T2, and T3 at different times corresponding to the call.

In Fig. 4, the average of the above-mentioned server times T1, T2, T3 is represented as Cav, the deviations of the server times T1, T2, T3 based on the average Cav are represented as C1, C2, C3, the allowable error range is represented as PL, and the server synchronization judgment range is represented as PG. Here, the allowable error range PL and the server synchronization judgment range PG can be set in the error detection unit (15) and the synchronization control unit (14) of the advertisement server (10), and the allowable error range PL is for providing an offset value described later to the set-top box (30) corresponding to a server time with a large deviation, and the server synchronization judgment range PG is for judging the synchronization type by the deviations C1, C2, C3 of the server times T1, T2, T3. The allowable error range PL and the server synchronization judgment range PG are set to have a preset range based on the average Cav, and it is preferable that the server synchronization judgment range PG has a range larger than the allowable error range PL.

Hereinafter, the operation of the advertisement server (10) and set-top boxes (30) will be described with reference to FIGS. 2 and 3.

In the advertisement server (10), the synchronization control unit (14) performs error detection (S10) for each set-top box. To this end, the synchronization control unit (14) generates server times T1, T2, and T3 corresponding to calls of the set-top boxes (10) of the operating times D1, D2, and D3 of the advertisement content, and provides the server times T1, T2, and T3 to the error detection unit (15).

The error detection unit (15) receives server times T1, T2, and T3 for error detection from the synchronization control unit (14) and determines the synchronization type corresponding to the error of the set-top boxes (30) (S12).

More specifically, the error detection unit (15) calculates the server times T1, T2, and T3 to generate an average Cav, and generates deviations C1, C2, and C3 corresponding to the difference between the average Cav and the server times T1, T2, and T3. The error detection unit (15) determines the synchronization type according to the error of the server times T1, T2, and T3 of the set-top boxes by using the server synchronization judgment range PG set based on the average Cav. That is, the error detection unit (15) can generate synchronization type information by determining the synchronization type by comparing the server synchronization judgment range PG set based on the average Cav with the maximum deviation among the deviations C1, C2, and C3. In the case of Fig. 4, it can be understood that the deviation C3 corresponds to the maximum deviation.

The error detection unit (15) can provide synchronization type information that determines the synchronization type corresponding to the error of the set-top boxes (30) to the synchronization control unit (14).

The error detection unit (15) can determine that the synchronization type corresponds to set-top box-specific synchronization if the maximum deviation among deviations C1, C2, and C3 is within the server synchronization judgment range PG, and can determine that the synchronization type corresponds to server synchronization if the maximum deviation among deviations C1, C2, and C3 is outside the server synchronization judgment range PG, and can provide synchronization type information according to the above judgment result.

By the above configuration, the error detection unit (15) can provide the average Cav, deviations C1, C2, C3, and synchronization type information to the synchronization control unit (14) as a result of performing the synchronization error type judgment (S12).

The synchronization control unit (14) of the advertisement server (10) can determine the synchronization type as set-top box-specific synchronization or server synchronization based on the synchronization type information of the error detection unit (15) that varies depending on whether the maximum deviation of the server times T1, T2, and T3 corresponds to the server synchronization judgment range PG. That is, the synchronization control unit (14) can determine whether the synchronization type corresponds to a case where set-top box-specific synchronization is required (S14) or a case where server synchronization is required (S16) by referring to the synchronization type information.

If the synchronization type is synchronization by set-top box (S14), the synchronization control unit (14) of the advertisement server (10) checks whether offset control or pause control (S20, S24) is performed and performs offset control (S22) or pause control (S26). At this time, the synchronization control unit (14) can selectively perform offset control (S22) or pause control depending on whether pause control information is received from the set-top box (30). The offset control (S22) may be understood as providing offset values for controlling the offset of some set-top boxes when pause control information is not received, and the pause control (S26) may be understood as corresponding to the case where pause control information is received. The pause control information may be understood as information provided from the synchronization player (33) to the synchronization control unit (14) to notify that the set-top box (30) has paused the next advertisement content due to an error.

And, if the synchronization type is server synchronization (S16), the synchronization control unit (14) of the advertisement server (10) checks whether it is jump control or reset control (S30, S34), and performs jump control (S32) or reset control (S36) to control the operation of the next advertisement content in the same way as jump or reset of all set-top boxes (30).

First, in the advertisement server (10), the synchronization control unit (14) receives the synchronization type information, average Cav, and deviations C1, C2, and C3 provided from the error detection unit (15) for offset control (S22), generates offset values for some deviations that fall outside the allowable error range PL, and provides the offset values to set-top boxes corresponding to some deviations.

More specifically, the synchronization control unit (14) may be configured to generate offset values for deviations of at least two set-top boxes (30) having the largest difference from the average Cav, and provide the offset values to at least two set-top boxes (30) corresponding to the deviations.

The above-mentioned offset control (S22) can be explained with reference to Fig. 5.

For example, the deviations of at least two set-top boxes (30) having the largest difference from the average Cav may be selected as those corresponding to the fastest and slowest server times among the deviations out of the allowable error range PL, and in the case of Fig. 4, it may be understood that the deviations C1 and C3 correspond to server time T1 and server time T3. In this case, the synchronization control unit (14) may generate offset values for the deviations C1 and C3 and provide the offset values to the set-top boxes (30) corresponding to the deviations C1 and C3 (S40).

Set-top boxes (30) can perform operations corresponding to the offset control (S22) of the above-described advertisement server (10) by having a synchronization player (33) and an offset control unit (35).

More specifically, the synchronization player (33) transmits the offset value to the offset control unit (35) when the offset value is received from the synchronization control unit (14) of the advertisement server (10). The offset control unit (35) stores the offset value transmitted as described above, and can provide the offset value when the synchronization control unit (14) drives the advertisement content.

Accordingly, the synchronization player (33) can change the running time of the next advertising content by applying the offset value provided from the offset control unit (35) (S42).

Here, the application of the offset value can be understood as adding the offset value to the originally scheduled running time of the next advertising content, and the synchronization player (33) can run the next advertising content at the changed running time by applying the offset value as described above.

By the above-mentioned offset control (D22), the deviations in the operating times of the set-top boxes (30) that are out of the allowable error range PL can be reduced. Therefore, if the deviations are continuously managed to satisfy the allowable error range PL by the present invention, the operating times of the set-top boxes (30) for simultaneously transmitting advertising content can be controlled in a good state by mutual synchronization.

Meanwhile, pose control (S26) can be explained with reference to Fig. 6.

Set-top boxes (30) can control pause for advertising content by the operation of the synchronization player (33) and pause control unit (36).

When an offset value for offset control is received, the synchronization player (33) transmits the offset value to the offset control unit (35) and provides information on providing the offset value to the pause control unit (36).

The pose control unit (36) counts the number of times the offset value is provided and determines whether an error has occurred in which the offset value is provided more than the allowable number of times (S50). For example, the allowable number of times may be preset by the manufacturer, such as 3 times.

The pose control unit (36) checks that an error has occurred if offset values are continuously received exceeding the allowable number of times (S52) and can provide pose control information to the synchronization player (33).

The synchronization player (33) can control the next advertisement content to be paused at the next advertisement content's running time in response to the pause control information of the pause control unit (36) (S54) and transmit the pause control information to the advertisement server (10).

The advertisement server (10) can control the remaining set-top boxes to pause the next advertisement content at the time of operation when the next advertisement content is paused on a specific set-top box (30).

Therefore, the synchronization control unit (14) of the advertisement server (10) can control the pause for the remaining set-top boxes (30) when pause control information is received from a specific set-top box (30).

When the synchronization control unit (14) controls the pause of the remaining set-top boxes (30), the synchronization players (33) of the remaining set-top boxes (30) can control the next advertisement content to pause at the operating time of the next advertisement content and notify the synchronization control unit (14) that they have entered the pause.

The synchronization control unit (14) of the advertisement server (10) may be configured to provide a re-execution command to simultaneously drive the next advertisement content of all set-top boxes (30) that have been paused in synchronization with the pause of the last set-top box when all set-top boxes (30) pause the next advertisement content.

The entire set-top box (30) can execute the next advertising content when it receives a re-execution command from the advertising server (10) (S56).

Meanwhile, the advertisement server (10) may be equipped with a jump control unit (16) for the above-described jump control (S32) and a reset control unit (17) for the above-described reset control (S36).

Here, jump means moving the initial position of the advertisement content to the time set as the event time. And reset means deleting all advertisement contents AD1, AD2, and ADn stored in the advertisement storage unit (38), receiving the advertisement contents again from the advertisement server (10), storing them in the advertisement storage unit (38), and then operating the stored advertisement contents again.

The above-mentioned jump control (S32) can be controlled by the jump control unit (16) of the advertisement server (10).

The jump control unit (16) may be configured to provide jump information that sets the average Cav as the event time when the synchronization type information provided from the synchronization control unit (14) corresponds to a jump that moves the initial position of the advertisement content.

Additionally, the synchronization control unit (14) can be configured to provide jump information as server synchronization information to all set-top boxes (30).

Accordingly, all set-top boxes (30) can drive the advertising content by moving the initial position of the advertising content to the event time in response to the jump information.

Jumps can be used for more precise and natural adjustments than poses over long time errors. For this purpose, it is preferable that the jump control unit (16) be configured to set the average Cav as the event time.

In addition, reset means that all set-top boxes (30) delete all the advertisement contents AD1, AD2, and ADn stored in the advertisement storage unit (38), then receive the advertisement contents again from the advertisement server (10), store them in the advertisement storage unit (38), and then run the stored advertisement contents again.

The above reset can be controlled by the reset control unit (17).

The reset control unit (17) can be configured to provide reset information when the synchronization type information provided from the synchronization control unit (14) corresponds to reset.

The synchronization control unit (14) can be configured to provide reset information as server synchronization information to all set-top boxes (30).

Accordingly, all set-top boxes (30) can delete all of the advertisement contents AD1, AD2, and ADn stored in the advertisement storage unit (38) in response to the reset information, receive the advertisement contents again from the advertisement server (10), store them in the advertisement storage unit (38), and then run the stored advertisement contents again.

The above jump and reset can be controlled by the synchronization type information corresponding to the case where the maximum deviation of the server times T1, T2, and T3 is outside the server synchronization judgment range PG.

The reset control unit (17) may be configured to provide reset information for reset by synchronization type information corresponding to at least one of a call by set-top box or an index error of the drive time, and an unknown synchronization error, if a maximum deviation greater than that determined by a jump occurs. At this time, the call by set-top box or an index error of the drive time and the unknown synchronization error may be determined by referring to error information generated while the synchronization control unit (14) is performing communication with the set-top boxes (30), and the synchronization control unit (14) may be configured to provide the synchronization type information for reset to the reset control unit (17).

The above-described embodiment of the present invention can determine the type of synchronization as set-top box-specific synchronization or server synchronization depending on whether the maximum deviation of the server times of the advertisement server (10) falls within the server synchronization determination range.

And, in the case of synchronization of set-top boxes, the embodiment of the present invention can perform offset control by generating offset values corresponding to the difference between the server times of some set-top boxes and the above average, and providing the offset values to some set-top boxes to change the running time of the next advertising content to the offset value. And, in the case where the above offset control exceeds the allowable number of times, a pause is performed on all set-top boxes so that all set-top boxes can be re-executed to run the next advertising content.

Additionally, in the case of server synchronization, the embodiment of the present invention can control the driving of the next advertising content in the same way, such as by jumping or resetting all set-top boxes.

The above-described embodiment of the present invention is configured so that the driving times for driving advertising content of set-top boxes (30) can be mutually synchronized by methods such as offset control, pause control, jump control, and reset control.

Accordingly, the present invention can resolve errors in the operating times of advertising contents running at the same time on multiple set-top boxes by mutually synchronizing the operating times of the set-top boxes.

As a result, the present invention can obtain an improved advertising effect because advertising content can be displayed at the same time on multiple display devices, and can obtain the effect of improving the reliability of the advertising transmission system.
