The present invention relates to a content delivery method, a content presentation method, a content delivery device, and a content presentation device.

With the development of multimedia receiving terminals, various kinds of contents have been produced. Here, the content is a generic term for content or information that is produced in the form of text, code, voice, sound, image, video, and the like and transmitted through a broadcasting network or a communication network.

When a content transmitting side such as a broadcasting company or a communication service provider transmits content such as advertisement content to a wired or wireless communication network, the receiving side receives the content from the communication network and expresses the content. The content may be produced on the content transmission side, or there may be a separate producer.

As an example of advertising content, a separate advertising production company may produce advertising content, a transmitting side such as a broadcasting station may transmit the advertising content, and a receiving side may express or display the advertising content to view or listen to the advertisement. As such, one piece of content is the subject of a business model with different subjects in production, delivery, and presentation.

Such content may be received and displayed by a receiving terminal such as a television or a mobile cellular phone. If the receiving terminal has a DVR function, the content may be stored and later displayed.

Here, the DVR (Digital Video Recorder) refers to any hardware or software platform that the user can store digital video contents (hereinafter, the same meaning is used herein). Accordingly, in the present specification, a digital video recorder (DVR) is used as a concept that includes a settop box, a digital television set, and a personal video recorder (PVR).

For example, when a transmission medium such as broadcast includes content such as an advertisement and transmitted, a receiving terminal having a DVR function may select and display the content after storing the transmitted content. This selective presentation method has a problem that the conventional content business model can be ignored. In other words, the DVR function of the receiving terminal can be displayed except for the advertisement content in the stored broadcast, which may be a technical problem in the advertisement content production company or the advertisement content transmission side having the purpose of expressing the content. .

Since the advertisement content transmitted together with the broadcast can be excluded and expressed by the DVR function of the receiving terminal, the content producer or broadcaster has a problem in that it cannot have an advertisement effect by the conventional business model.

In general, a digital device including a mobile communication terminal requires a boot time when the digital device is turned on and an application termination time when the digital device is turned off.

In addition, when a terminal connected to a broadcasting network or a communication network switches channels of digital broadcasting, receives and displays an application through a wireless Internet connection, or the like, or displays a received digital broadcasting or application when loading a stored application. It cannot be ignored.

Hereinafter, a terminal is a generic term for a device connected to a wired / wireless broadcasting network or a communication network to receive information or to display received information. In addition, hereinafter, an application is used to mean a program or code that can implement a certain function in a terminal, or conceptually, an implementation function itself that is implemented by a certain program or code.

As described above, when the terminal is turned on / off, the broadcast channel is switched, the received content is decoded, or an event such as an Internet connection occurs, the terminal may not display the content or application due to the occurrence of the event.

For example, when a communication terminal such as a digital television or a mobile communication terminal switches a broadcasting channel from a channel that is currently displayed to another channel, the time that the terminal cannot display the broadcast is currently about 5 seconds. Can't watch the broadcast.

Therefore, a viewer of a terminal that can receive a broadcast or use for communication has a problem that the user may have a discomfort due to the event of the terminal as described above.

The present invention is to solve the above problems, an object of the present invention is a content transmission method, content presentation method, so that the user does not feel uncomfortable due to a terminal event, such as a channel change of the receiving terminal of the broadcast or communication, A content delivery device and a content presentation device are provided.

Another object of the present invention is to provide a content transmission method, a content presentation method, a content transmission device, and a content presentation device that a content transmission side such as a broadcasting station can control whether or not the content reception terminal displays the content.

It is still another object of the present invention to provide a content transmission method, a content presentation method, a content transmission device, and a content display device that can display content such as an advertisement when an event occurs in a receiving terminal.

Content delivery method of the present invention for achieving the above object comprises the steps of generating the content and the content presentation time information; Converting the generated content and content presentation time information into a transmission data format; And transmitting the data in the converted format.

The content is advertising content, and the content presentation time information is preferably transmitted including a content presentation event type and waiting time information for causing the content to be displayed.

In addition, the content presentation method of the present invention comprises the steps of receiving data including the content and the content presentation time information; Storing the received content and content presentation time information; And processing and displaying the stored content based on the content presentation time information according to whether a content presentation event calling the stored content occurs.

In addition, the content presentation device of the present invention includes a memory unit for storing the content and the content presentation time information for controlling the presentation of the content; A controller configured to process the presentation of the stored content based on the content presentation time information according to whether a content presentation event calling the stored content occurs; And an output unit for displaying the content processed according to the content presentation time information.

The objects, features and advantages of the present invention will be more readily understood by reference to the accompanying drawings and the following detailed description. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the description thereof will be omitted.

1 is a diagram illustrating an example of a structure of data that can be transmitted by a content delivery method and a content delivery device according to the present invention.

In order to facilitate the description of the present invention, the content to be transmitted is broadcast advertisement content, and the advertisement content is described as an example of a case where the content is transmitted as an image group or a video content. However, the present invention is not limited thereto, and the same idea may be applied to other contents, and may also be applied to transmission of contents through a wired or wireless communication network rather than a broadcasting network.

Referring to FIG. 1 conceptually describes a content delivery method and a content delivery device according to the present invention.

When broadcasting data is transmitted, content presentation information that can be expressed together can be added and transmitted. The content transmission side, such as a broadcasting station, can add various content presentation information to the transmission signal, thereby controlling various content to be displayed at the receiving terminal.

An example of the data structure including the content presentation information of FIG. 1 includes a first field to which information related to the structure of data of the content to be transmitted belongs, a second field to which additional information required when the content is displayed, and a row for content It may include a third field to which data (raw data) belongs.

The first field may be referred to as a header field that can be transmitted together when transmitting content. In addition, since the third field is a field for transmitting data about the content, it may be generally called a data field or a body field. Therefore, the terminology used herein is not to be construed as limited to its name, but to be construed in a sense of the term.

Hereinafter, the second field is referred to as an additional information field. The additional information field is content presentation information required when displaying content, and may include information related to the type of content, a method of displaying the content, and the like. In particular, the content type according to the present invention represents a feature that is stored by the content presentation information, not the output and volatized data, and reproduced according to the content presentation information when an event occurs. Therefore, the content presentation information may be used in various business models according to the intention of the content provider as the control information of the content.

The content presentation information may belong to any of the fields described above, but it is preferable that the content presentation information is included in the additional information field to which necessary information belongs when the content is displayed.

In general, as shown in FIG. 1, content and content presentation information are transmitted together, but are not necessarily transmitted together. For example, a content producer may separately produce and transmit content, and the content presentation information may be transmitted by a side that wants to control the content presentation of a receiving terminal such as a broadcasting station or a communication service provider.

In addition, one content may be transmitted in one file, may be transmitted in multiple files, and one content presentation information may include information necessary for expressing a plurality of content files.

2 (a, b) shows an embodiment of the structure of the additional information field when the content presentation information that can be transmitted by the present invention is included in the additional information field. 2A illustrates a case in which the transmitted content is a slide, and FIG. 2B illustrates a detailed information field including content presentation information according to the present invention when the transmitted content is a video.

The content presentation information includes a field (a) that defines whether to display content when an event occurs in the receiving terminal. In order to control the presentation of the content to the content receiving side, the content transmitting side transmits by including information on whether the content is displayed in the field (a). At this time, if the transmitting side of the content according to the present invention is a broadcasting station, the information includes corresponding broadcasting station information of the transmitted content, that is, information such as a channel ID and the like. This allows the transmitted content to be displayed as an advertisement function in the receiving terminal, thereby forming a business model of a broadcasting station, an advertiser, and a terminal 3.

In the example of FIG. 2 (a, b), when the field (a) is 1, the receiving terminal stores the corresponding content and plays the stored content when the display event occurs in the terminal. (a) If the field is 0, it means that the content transmitted to the receiving terminal is not stored.

The content presentation information includes a (b) field that defines when the content is displayed. In the example of FIG. 2 (a, b), the field (b) corresponds to the presentation time of the content, and is transmitted to the terminal including information on the presentation time of the stored content according to the type of presentation event occurrence. The content presentation time is determined by the event content and the running time during the event occurrence when the event of the terminal occurs. For example, the types of events that can display content on the terminal are based on the occurrence of events such as a broadcast channel switching event, an on / off event of the terminal, an attempt to connect to the network of the terminal, an incoming call notification event, and a shadow area movement event. It can be provided in various ways and controls when the stored content is displayed. In addition, the running time during the event occurrence of the terminal is represented by time information such as 1 second, 3 seconds, 5 seconds of the standby state when the event occurs, which is a statistical value of the terminal. The idle state of an event occurrence according to the present specification refers to a state in which a processor is waiting for some condition to enter a state in which a processor to be executed from a controller is operated. For example, a state of waiting for an input / output process by an event occurrence to be completed. And so on. Accordingly, the stored content of the stored content is controlled by the duration of the standby state according to the event occurrence type.

As an example, when the standby state time takes about 3 to 4 seconds when switching channels in the broadcast terminal, the presentation time of the stored content is preferably set to 3 to 4 seconds. When the mobile receiving terminal moves to the shaded area, the presentation time of the stored content in the idle state for a predetermined time is preferably provided at a corresponding time.

In the terminal, various events may exist in addition to the examples listed above. For example, there may be an event for executing a new application on the terminal, and there may be an event controlled by a user's key input. It is desirable to determine the statistical time of the idle state for each event occurrence and to determine the content presentation time by classifying various event occurrence paths.

The present invention is characterized in that the content presentation time is determined in accordance with the idle state condition after the event of the terminal. Accordingly, the content presentation time may be provided according to these various events (0x00 to 0xFF), and the terminal may express the content stored by the content presentation information received when the event occurs.

As another example, an event in which a mobile communication terminal receiving a broadcast enters a shaded area of the broadcast and the power of the broadcast wave falls below a predetermined level may be set in the field (b). In such a case, the terminal can express the content according to the content presentation information.

Therefore, hereinafter, an event that can be defined in the content presentation information to express the received and stored content is collectively referred to as a content presentation event. When a content presentation event occurs in the terminal, the receiving terminal may display content according to the event.

In the example of Fig. 2 (a, b), the content presentation information includes a field (c) which defines the dimension on the image that appears on the screen when the image content is displayed. Each of the left and right eyes is presented with the same image as seen from the left and right directions, giving parallax to both eyes, and combining each of the images by the two eyes allows one three-dimensional image to be seen.

Therefore, if two two-dimensional images are properly synthesized, the image expressed using binocular parallax can be seen as a three-dimensional image. After synthesizing the image (R) seen by the right eye and the image (L) seen by the left eye, the synthesized image may be viewed as a three-dimensional image. Therefore, for one image, the image of the right eye and the image of the left eye are prepared, and when the left image (L) and the right image (R) are combined in units of pixels, a three-dimensional image can be seen from a human perspective. Can be. The method of composing the two images may be mainly an interpolation method, but may vary depending on the method of forming the image.

Therefore, when the image is continuously reproduced in three dimensions, content having a video having a three dimensional image may be displayed. The field (c) defines whether or not the content may be expressed in three dimensions. 2 (a, b) shows that the 2D content is displayed when the field (c) is 0 and the 3D content is displayed when the field is 1 (c).

In the example of FIG. 2 (a, b), the content presentation information includes identification information of the content service provider to be transmitted in the (d) field. Since the transmitted content can be expressed as an advertisement function in the receiving terminal, the content presentation time can be set by using the identification information of the content service provider for various content presentation events of the receiving terminal, so that broadcasting stations and mobile communication service providers or broadcasting stations and terminal manufacturers Your business model.

In the example of FIG. 2 (a, b), when the content service provider is a mobile communication service provider, a value 0 to Z, which is identification information of the mobile communication service provider, is transmitted to the (d) field and stored together with the content transmitted to the receiving terminal. . Content display time using the identification information of the content service provider is when a specific event of the receiving terminal, i.e., when the receiving terminal is connected to the mobile communication network (waiting time for incoming and outgoing calls, waiting time for text transmission, waiting time for wireless Internet connection, etc.) Corresponds to the content presentation event that occurs. Accordingly, in response to identification information of a mobile communication service company subscribed to by a receiver terminal, L stores content provided by LGT communication company and S stores content provided by SKT communication company.

As another embodiment of the present invention, when the content service provider is a terminal manufacturer (not shown), the content service provider is indicated and transmitted in the (d) field. This allows the content stored by the manufacturer of the receiving terminal to be displayed during the waiting time when the event of the power-on / off event of the receiving terminal is expressed.

In the example of FIG. 2 (a, b), the content presentation information includes information of the best-fit and first fit, which are the priority scenes, according to the content presentation event in the (e) field. This makes it possible to partially output the main scene of the content when the waiting time according to the event occurrence is shorter than the presentation time of the content. The best-fit / first fit information for this purpose is set and transmitted so that a predetermined amount can be expressed in the front direction or the rear direction based on the presentation scene reference of the content transmitted in 1 byte. In addition, 2 bytes are transmitted including a slide position which is a reference for a scene in which content is expressed. On the basis of this slide position, it is possible to detect and output a predetermined minute by the waiting time before or after.

According to another embodiment, the best-fit and first-fit information of the content may be transmitted by inserting priority presentation information into content data to be transmitted when generating content presentation information. Important scenes such as corporate logos are first reproduced by priority display information, and a general first fit allows content data to be expressed in chronological order by the waiting time with priority to the first image data of the content.

In the example of FIG. 2 (a, b), the content presentation information includes information in which the transmitted content is forcibly expressed in the (f) field and transmitted. If the content presentation event according to the present invention is not generated by the user for a predetermined time (for example, in the application driving state, such as watching the user's broadcasting, listening to music, etc. in the terminal) by transmitting the information including the forced expression, forcing the presentation information Represents a value of 1, the content stored in the PIP (Picture in Picture) method is overlaid on the running screen. The forced expression information is preferably transmitted including the expression format (period, number of times) of the stored content.

In the example of Fig. 2 (a, b), the content presentation information is set to the validity period in which the transmitted content can be stored and expressed and transmitted in the (h) field as the content presentation amount. According to an embodiment, the amount of content to be displayed can be transmitted by setting the storage period of the transmitted content in units of days, and the content after the storage period is no longer displayed and deleted from the storage space to efficiently manage memory. Be sure to According to another embodiment of the present invention, the stored content is set to the number of times of expression such that the stored content is displayed and deleted 100 times and transmitted. The storage period of the content is provided as a business model between the advertiser and the broadcaster who received the advertisement content.

Therefore, when the receiving terminal moves the stored advertisement content including the guaranteed number of times to a shaded area indicating a long standby state, the receiving terminal does not receive the broadcast signal for a predetermined time, so that the stored content having the guaranteed number of times is displayed. It is preferable without boring on the side.

In the example of FIG. 2A, the content presentation information is preferably provided by including the number of content slides in the (i) field when the transmitted content is a slide show. In the example of FIG. 2A, the field (i) indicates the number of content slides that can be displayed when an event occurs in the terminal from 0 to 99. When the content transmitted according to an embodiment of the present invention is a slide show, a plurality of slide image files may form one content group, and slides belonging to the content group may be expressed as a slide show.

In the example of FIG. 2A, when the content is expressed, the content presentation information may be transmitted including a field (j) indicating information on the serial number of the content file in the group to which the stored content file belongs. In the example of FIG. 2A, the (j) field indicates the serial numbers of the contents in a group from 0 to 99, and indicates the serial numbers of two images capable of forming a three-dimensional image when the displayed content is on the three-dimensional image. Can be. In the example of FIG. 2A, an even number represents a serial number of an image L visible to the left eye, and an odd number represents a serial number of an image R visible to the right eye, respectively.

In FIG. 2A, the content presentation information may include a field (q) indicating information about a time indicating the presentation interval in the content group. The (q) field defines the slide display time interval in the group when the content is expressed in the slide group unit. In the example of FIG. 2A, the slide display interval is set to 0.1 seconds (0.1 to 9.9 sec).

In (a) and (b) of FIG. 2, the content presentation information may include a (l) field that defines a content ID serial number. In the example of Fig. 2 (a, b), the group ID serial number of the content to be stored may be from 0 to 999999.

In FIG. 2B, when the content to be transmitted is a video, the content presentation information includes (g) a field defining a presentation method according to an error occurring during reception. In the example of FIG. 2B, when an error occurs with a value of 1 depending on whether an error occurs, a method (0) of displaying only a received portion of video content and a method (1) of displaying a first image frame in a slide show are provided.

Content and content presentation information according to the present invention is preferably included in the image transmission protocol and transmitted. 3 (a) and 3 (b) are a multimedia object transfer (MOT) protocol capable of containing transmission data that can be transmitted by a content transmission method and a content transmission device according to the present invention.

The concept of realizing the content transmission method and the data that can be transmitted by the content transmission apparatus according to the present invention will be described in detail with reference to FIGS. 3 (a) and 3 (b) as follows.

 One of the broadcast and communication transmission protocols is the Multimedia Object Transfer (MOT) protocol.

First, FIG. 3 (a) is a diagram illustrating some data fields of a multimedia audio broadcasting (DAB) MOT protocol of ETSI EN 301 234 V2.1.1. The fields described in FIG. 2 may be defined in a reserved area of the MOT protocol. In FIG. 3A, unspecified regions are shaded. Alternatively, the transmission data may be defined in a field having a parameter designated area but not used for a special purpose.

In order to expand the content delivery method and the content delivery device according to the present invention, it is preferable to define content presentation information in a variable length data field among unspecified areas of the MOT protocol. The example of FIG. 3 (a) shows that data including the field described with reference to FIG. 2 can be inserted into a Content Name field (a) which is a designated area having a variable length. Since the use of the Content Name field is optional in the current MOT protocol, content presentation information can be transmitted using this.

3 (b) is a property indicator for the Content Name, in which the shaded parts indicate that the Content Name field is filled with Arabic numerals and transmitted. Therefore, the data field described above may be defined as an ASCII value of Arabic numerals.

When the content presentation information is transmitted by inserting the data field and the data field value illustrated in FIG. 2 into the Content Name of FIG. 3 (a), the receiving terminal may display the content when the terminal event occurs according to the content presentation information. .

In addition to the MOT protocol, the above transmission data can be transmitted by other broadcast transmission protocols or communication transmission protocols, and the MOT protocol is only one specific example.

As another example of transmitting content presentation information, content presentation information may be transmitted through a data field of a sub broadcast or a data broadcast channel in addition to a data field of a main channel. When transmitting using a data broadcasting protocol, the above-described information may be transmitted using a binary format for scenes (BIFS). In addition, the content presentation information can be transmitted using a wired or wireless communication protocol.

4 is a block diagram showing an embodiment of a content transmission device according to the present invention. An embodiment of a content delivery device according to the present invention will be described with reference to FIG. 4. An embodiment of the content transmission device according to the present invention may include a content presentation time information generating unit 110, a content storage unit 120, a data converter 130 and a transmission unit 140.

An operation of an embodiment of a content transmission device according to the present invention will be described with reference to FIG. 4 as follows.

The content presentation time information generation unit 110 may generate presentation time information about an event type for causing the content to be transmitted to be expressed in the terminal and an idle time accordingly. The content presentation time information generation unit 110, together with a field for transmitting the content whether the content is displayed, priority information of the content scene according to the presentation time, Best-fit / First fit information, forced presentation (PIP) information, content storage period, A content presentation information field including content direct provider (broadcaster) information, content indirect provider (mobile telecommunication company, and terminal manufacturer) information may be generated. And information field about the dimension of the image in which the content is expressed, information on the number of files in the content, information on the serial number of the files in the group to which the content belongs, information on the display interval between content groups, and the content group number. At least one of the information is further generated.

The content storage unit 120 may store content to be transmitted. The stored content may be content generated in the content delivery device itself, or may be content received and stored from the outside of the content delivery device. The transmitted content refers to advertising content produced in a capacity that can be inserted at idle time when an event of the terminal occurs.

The data converter 130 may convert the data into a data format for transmitting content. The data format may be a format according to a protocol for transmitting broadcast signals when the format of the data to be transmitted is broadcast. And if the format of the transmission data is a two-way wireless communication may be a data format according to the communication protocol. That is, the data converter 130 may convert the content data to be transmitted into a physical layer through which the data is transmitted.

Therefore, when the transmission data format is a broadcast signal, broadcast signals such as terrestrial, satellite, and cable may be converted into a physical layer, and when the transmission data format is a communication signal, it may be converted into a physical layer according to wired and wireless communication.

The transmitter 140 may transmit content data converted into a physical layer according to a wired / wireless broadcasting and communication protocol through a wired or wireless network.

5 is a block diagram showing an embodiment of a content transmission method according to the present invention. An embodiment of a content transmission method according to the present invention will be described with reference to FIG. 5. First, content and content presentation time information and corresponding content presentation information may be generated (S10). The content presentation time information is as described above. In operation S20, the content and the content presentation information according to the content presentation time may be converted into a transmission data standard. The content data converted to the transmission standard may be transmitted (S30).

6 is a block diagram showing an embodiment of a content display device according to the present invention. In the exemplary embodiment of FIG. 6, the content display device includes a signal receiver (tuner) 210, a signal demodulator 220, a demultiplexer 230, a memory unit 240, a content display controller 250, and a content decoder 260. ), A content processor 270, and an output unit 280.

Referring to Figure 6 describes the operation of an embodiment of the content display device according to the present invention.

The signal receiver 210 may receive a broadcast signal or a signal for mobile communication. In general, the mobile communication terminal may include a signal receiver for receiving a broadcast signal and a signal receiver for receiving a communication signal. Accordingly, the signal receiver 210 of FIG. 6 may be a broadcast receiver that receives a broadcast signal or may be used as an RF receiver for mobile communication. The signal receiver 210 according to an exemplary embodiment of the present invention receives broadcast data including content and content presentation time information. To this end, tune the frequency of the selected broadcast channel. The broadcast data output from the signal receiver 210 at the intermediate frequency IF is demodulated in the same manner as the modulated signal from the signal demodulator 220 and output as a digital signal. The demultiplexer 230 separates video, audio, and data signals from the modulated broadcast signal. At this time, the content and the content presentation time information transmitted by the present invention is extracted.

The content decoder 240 decodes the extracted content and content presentation time information. According to an embodiment of the present invention, a video stream of a multimedia broadcasting (DMB) signal is decoded by an MPEG4 AVC decoder, an audio stream is decoded by an MPEG4 ER-BSAC decoder, and a data stream is decoded by using an MPEG4 BIFS decoder.

The memory unit 250 stores the decoded content and content presentation time information. At this time, the memory unit 250 includes a content presentation information storage unit 253 for storing the content presentation time information and a buffer which is a content storage unit 251 for storing the transmitted content. In an embodiment, the memory unit 250 sequentially stores and receives the content and the content presentation time information received through the corresponding channel while the terminal receives and reproduces the broadcast signal.

The content display control unit 260 determines whether a content display event of the terminal occurs, and when the event occurs, expresses the stored content based on the content display time information from the memory unit 250. The content presentation control unit 260 extracts a corresponding terminal manufacturer from the received content presentation time information, and controls the content presentation time information, corresponding content corresponding to the event type and event occurrence time of the terminal, to be output. In this case, the content presentation event may include various events such as channel switching, device on / off, connection to a communication network, and communication incoming.

The content processor 270 performs image processing and audio processing on the decoded content based on the content presentation time information. For example, if the content presentation event occurrence waiting time is shorter than the content presentation time, the content is output from the information of Best-fit / First-fit of the content with the set number of slides or the length of the video according to the length of time, When the presentation event does not occur, the stored content may be output by overlaying the stored content with a screen reproduced in a picture in picture (PIP) manner by forced presentation information. In addition, when the content presentation device is moved to a shaded area in which the broadcast reception state is poor and the content presentation event occurs, the content presentation apparatus processes the stored content according to the transmitted content guarantee presentation number in order.

The output unit 280 may express the content processed by the content processor 270 according to the control signal of the content display control unit 250. The output unit 280 may be a display panel for visually displaying content or a speaker for outputting sound. In this case, the display panel may drive a 2D screen and a 3D screen.

In particular, the content to which the present invention is applied does not allow data to be received and volatilized at the multimedia receiving terminal, but content data transmitted from a broadcasting station, which is a service provider, to be forcibly stored, and content that is control data so that the stored content can be reproduced in a specific environment. It is characterized by including the display timing information. Content presentation method according to the present invention is an embodiment to which the concept of the present invention is applied can be described in detail as a method implemented between a broadcasting station for transmitting broadcast data and a mobile receiving terminal for receiving the same.

Since the mobile receiving terminal, which is the content display device, displays the stored content according to the content display time information, the broadcasting station which is the content transmission side may control whether the mobile communication terminal displays the content by using the content display time information.

In order to easily understand the operation of the content display device, it is assumed that the content display device is a mobile receiving terminal, the content is advertising content for broadcasting, and the user views the broadcast on the mobile receiving terminal. And it is assumed that the mobile receiving terminal receives the broadcast transmitted from the first broadcast station.

The mobile receiving terminal may receive and store the content and the content presentation time information through the broadcasting network of the first broadcasting station. When the user changes the channel from the channel transmitted by the first broadcaster to the channel transmitted by the second broadcaster, the mobile terminal changes the advertisement content according to the content presentation time information received from the first broadcaster. Can be expressed.

Alternatively, the advertisement content received by the first broadcasting station may be displayed on the idle screen generated when the mobile receiving terminal is turned off according to the content display timing information. The advertisement content includes a broadcaster channel ID, which is a direct content provider, from the content presentation time information. The mobile receiving terminal allows the mobile terminal to display the advertisement content transmitted through the fixed channel when the broadcast reception ends.

Since the user can watch the content provided by the content transmission side such as an advertisement at the time of the content presentation event such as the channel change time, the user can eliminate the discomfort waiting for the conventional screen conversion.

As another example, the content presentation time information may be transmitted including terminal manufacturer information which is an indirect content provider. The type of the content presentation event and the event occurrence time (standby state duration time) are different for each terminal manufacturer, and according to the terminal information, the content presentation time information is changed according to the terminal information to control the presentation of the transmitted content.

As another embodiment, the content presentation time information is transmitted by setting the best-fit / first-fit information of the transmitted content. This means that if the display time of the stored advertising content is longer than the waiting time when the event occurs, the priority scene of the advertising content is displayed during the waiting state of the event. For example, the corporate logo image of the advertisement content may be set as best-fit and displayed as a still image during a short event waiting time. In this case, when the transmitted content is a slide show, the selected slides may be displayed according to the content presentation criteria, and when the content is a video, the amount of content corresponding to the event occurrence time may be calculated and displayed according to the content presentation direction and criteria.

As another temporal concept, the event occurrence time of the mobile communication terminal may increase the standby state time when a message transmission event occurs due to an overload state of the communication network. In this case, the content presentation time information may be transmitted by setting a loop section for repeatedly playing the presentation time of the stored advertisement content. According to another embodiment of the present invention, the receiving terminal moves to the shadowed area to display the stored content to output the guaranteed number of times of guaranteed transmission of the transmitted content when the broadcast signal reception is limited.

7 (a, b, c) is a flow chart showing an embodiment of a content presentation method according to the present invention.

Referring to FIG. 7A, an embodiment of a content presentation method in a mobile receiving terminal according to the present invention will be described.

Data including content and content presentation time information is received (S200). Content and content presentation time information are extracted from the received data, and the content is decoded and output (S210). On the basis of the content presentation time information of the output content, it is determined whether the content is 'present content' (S220). As a result of the determination, when the information for displaying the content is set in the content display time information, the output content and the content display time information are stored (S240). Alternatively, if the information for displaying the content is not set in the content display time information in S220, the received content is not stored (S230).

Alternatively, the content received in S210 may not be displayed. That is, when the received content is transmitted on a sub channel such as a data channel, rather than the main broadcast channel, the received content can be output by a request signal to a user.

In operation S250, it is determined whether a content presentation event of the terminal occurs. If the content presentation event of the terminal does not occur, step A is entered. As shown in FIG. 7B, when the content presentation event of the terminal does not occur, the content presentation time information may be automatically displayed after a set time of stored content. Accordingly, when the terminal is in a driving state without generating a predetermined content presentation event, the terminal outputs the stored content by overlaying the stored content on a screen reproduced in a picture in picture (PIP) manner based on the content presentation time information. (S260, S261).

When the content presentation event occurs in the terminal in S250, the stored content selects the content to be expressed based on the content presentation time information (S270). In this case, the playing time of the displayed content according to the type of the content presentation event may be controlled by the content presentation timing information. In response to the occurrence of the content presentation event, it is determined whether the idle time of the terminal and the reproduction time of the displayed content are the same, and when the content is identical, the stored content is displayed as it is (S280, S281). If the idle time of the terminal and the reproduction time of the displayed content are not the same, the process proceeds to step B. In addition, if the presentation time of the stored content is shorter than the waiting time according to the content presentation event of the terminal (S290), the presentation of the stored content is repeatedly played until the waiting state of the content presentation event is terminated (S291). If the presentation time of the stored content is longer than the wait state of the content presentation event in S290, the content is expressed in the priority scene based on the best-fit / first-fit information of the stored content from the content presentation time information (S292).

On the other hand, the terms used in the present invention (terminology) are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of the skilled person in the relevant field, the definitions of which are used throughout the present invention.
