Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a flowchart illustrating a method of providing additional content according to an embodiment of the present invention.

Referring to FIG. 1, service information on a broadcast service is received while receiving a broadcast service (step 110). The service information is information for distinguishing broadcast services provided by a plurality of broadcast service providers. Next, a trigger for instructing to insert additional content into the broadcast service being received is received (step 120). The trigger may be received from a server corresponding to the location information of the trigger transmission server included in the service information. However, the method of receiving a trigger is not limited thereto, and for example, the trigger may be received by filtering a transport stream of a broadcast service to obtain trigger information. Upon receiving the trigger, the service information is used to select additional content corresponding to the trigger (step 130). The service information includes information on at least one additional content. It compares the information included in the trigger with the information about the additional content included in the service information, and selects which of the additional content are to be played back. For example, the service information is searched to determine whether there is additional information corresponding to the information identifying the insertion of the additional content included in the trigger and the information identifying the additional content, and switching to the additional content such as location information if the additional content exists. Obtain information for The additional content is received and reproduced using the acquired location information (step 140). As such, the broadcast service provider may easily control trigger-based additional content insertion through service information on the broadcast service.

2 is a flowchart illustrating a method of providing additional content according to another embodiment of the present invention, which is an example of applying the present invention to the provision of an interstitial advertisement.

Referring to FIG. 2, service information during broadcast service reception is received (step 210), and when a trigger is received from the trigger transmission server described in the received service information (step 220), an advertisement is inserted with reference to the trigger information. If the received trigger is a trigger for instructing to end advertisement insertion (step 230), the process returns to the broadcast service being received (step 280). Whether the advertisement insertion termination instruction is determined may be determined by checking whether advertisement information corresponding to a trigger received among advertisement information included in the service information indicates whether to terminate advertisement insertion.

If ad insertion continues (step 230), it is determined whether advertisement information corresponding to information for identifying the advertisement insertion included in the trigger information exists in the service information (step 240). If corresponding advertisement information exists, it is determined whether advertisement information corresponding to the trigger advertisement identification information is included in the advertisement information classified by the advertisement insertion identification information (step 250). If there is no advertisement information corresponding to the trigger in steps 240 and 250, that is, if no information on the advertisement to be inserted is found, an underlying advertisement included in the broadcast service is played (step 290). If there is advertisement information corresponding to the trigger, the position information of the advertisement to be inserted is acquired (step 260), and the interstitial advertisement is received and played using the same (step 270).

3 is a block diagram showing a digital broadcast receiving apparatus according to another embodiment of the present invention.

Referring to FIG. 3, the digital broadcast receiving apparatus 300 includes a receiver 310 for receiving a broadcast stream for providing a broadcast service, service information for the broadcast service, a trigger, and additional content from a server (not shown), and a receiver. A control unit 320 for reproducing the data received through the 310 and outputting it to the display 340 and controlling the receiving unit 310 and the reproducing unit 330 to provide a broadcast service and additional content. Include. The server for managing and transmitting the trigger or additional content may be implemented as the same server as the broadcast server, but may be implemented as separate servers.

The control unit 320 immediately selects the additional content corresponding to the trigger using the service information upon receiving the trigger, and receives and reproduces the selected additional content using the location information included in the service information. The unit 330 is controlled. In addition, the controller 320 controls the insertion and reproduction of the additional content through the execution of the additional content providing method described with reference to FIGS. 1 and 2.

FIG. 4 is service information described to perform advertisement insertion according to another embodiment of the present invention. Service discovery & service selection (SD & S) of DVB-IP (Digital Video Broadcast-Internet Protocol), which is one of IPTV standardization organizations, is described. It is the Example which applied this invention to a specification.

SD & S is a technology for classifying a plurality of service information provided by a plurality of service providers in an HNED (Home Network End Device) at an IP level. HNED needs to identify the service provider and distinguish the services provided according to each service identifier because it is a structure capable of receiving services through multiple heterogeneous networks. The SD & S information includes service location information and replacement service information. When the SD & S information is transmitted by multicast, the SD & S information is transmitted in a transmission period of 30 seconds. When the HNED starts and the SD & S information is received, the receiver is set according to the SD & S information. When the advertisement insertion time arrives, the advertisement is inserted as described below.

Referring to FIG. 4, a <oif: DPI> element 410 is added below the <SI> element 405. The <oif: DPI> element 410 is a Real Time Streaming (RTSP) for receiving an XML (Extensible Markup Language) file having trigger information and information 420 and 430 about trigger-based interstitials to be executed in the corresponding <SingleService>. Protocol (Uniform Resource Locator) information (410).

The attribute "TriggerFrom" of the <oif: DPI> element 410 has a URL as an attribute value, which is information for receiving an XML file having trigger information from the URL. If the URL information of the trigger does not exist in the <oif: DPI> element 410, the transport stream of the broadcast service may be filtered to obtain trigger information including an advertisement insertion identifier and an advertisement identifier.

The <oif: DPI> element 410 may include <oif: Insertion> elements 420 and 430 having information about individual interstitial advertisements. As illustrated in FIG. 4, there may be a plurality of <oif: Insertion> elements. The <oif: Insertion> element has two attributes, "Id" and "EndofInsertion". "Id" has information for identifying an advertisement insertion as an attribute value, and "EndofInsertion" has information for indicating whether to end advertisement insertion as an attribute value. When inserting an advertisement, an <oif: Insertion> element is selected that has the advertisement insertion identifier of the trigger as the value of the "Id" attribute. The <oif: Insertion> element may include a plurality of <oif: InsertionUri> elements, and each <oif: InsertionUri> element may be identified by an attribute value of "InsertionCategory" and has position information of an individual interstitial.

If the attribute value of "EndofInsertion" is "false", it means to switch to the interstitial advertisement. Therefore, the <oif: InsertionUri> element (s) inside the <oif: Insertion> element is searched for location information on the advertisement to be inserted. As a result of the search, the URL information in the <oif: InsertionUri> element with the "InsertionCategory" attribute value corresponding to the advertisement identifier of the trigger XML document is obtained. If the attribute value of "EndofInsertion" is "true", it means to end the advertisement insertion. Therefore, regardless of the content of the <oif: Insertion> element, it moves to the broadcast service (primaryService) that is being received by referring to the <DVBTriplet> element 400. . In this case, the <oif: InsertionUri> element does not need to exist inside the <oif: Insertion> element 430.

If none of the <oif: Insertion> elements are included in the <oif: DPI> element, the underlying advertisement included in the transport stream will be broadcast without the insertion of an advertisement even if a trigger is received.

Referring to Figure 4 will be described in detail with respect to advertisement insertion. If the first trigger "trigger1.xml" is received from "rtsp: //advertisement.co.kr/ads/trigger" while receiving the broadcast service described in the <DVBTriplet> element 400, the received file is parsed ( parsing) to obtain an advertisement insertion identifier (Id) and an advertisement identifier (InsertionCategory). Assume that the "Id" value of "trigger1.xml" is 0x0001 and the "InsertionCategory" value is 0x01. The insertion proceeds because the <oif: Insertion> element 420 whose "Id" attribute value is 0x0001 is searched and the attribute "EndOfInsertion" of this element has a value of "false". Accordingly, the <oif: InsertionUri> element 421 whose "InsertionCategory" attribute value is 0x01 is searched for in the retrieved <oif: Insertion> element 420, and as a result, "rtp: //224.10 .1.1: 1234 "is obtained. The switch from the broadcast service to the interstitial advertisement is performed using this address information.

The second trigger "trigger2.xml" from "rtsp: //advertisement.com/ads/trigger" defined by the "TriggerFrom" attribute of the <oif: DPI> element 410 at the end of the broadcast of the interstitial. Is received. Assume that the value of "Id" in "trigger2.xml" is 0x1001. When this trigger is received, the <oif: Insertion> element 430 with the "Id" attribute value of 0x1001 is retrieved and the insertion should be terminated because the attribute "EndOfInsertion" of this element has a value of "true". Thus, it returns to the broadcast service described by the <DVBTriplet> element 400. Even though the attribute "EndOfInsertion" of this element 430 has a value of "false", since no sub element <oif: InsertionUri> exists, it will eventually return to the broadcasting service that was being viewed.

As described above, the broadcast service provider can easily perform a customized advertisement by inserting advertisement information into the SD & S. As a result, the viewer can increase the time for viewing the advertisement and maximize the advertisement effect.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited to the above-described embodiments, which can be variously modified and modified by those skilled in the art to which the present invention pertains. Modifications are possible. Accordingly, the spirit of the invention should be understood only by the claims set forth below, and all equivalent or equivalent modifications will fall within the scope of the invention. In addition, the system according to the present invention can be embodied as computer readable codes on a computer readable recording medium.
