Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a broadcast service providing method and apparatus capable of replacing broadcast contents in accordance with a user's entry into a channel.

The present invention relates to a broadcast service providing method and apparatus capable of replacing broadcast contents in accordance with a user's entry into a channel. More particularly, the present invention relates to a method and apparatus for selecting broadcast contents, And more particularly, to a method and apparatus for providing broadcast content in place of previously scheduled content.

The existing broadcasting service creates a transmission schedule for each broadcasting content in the broadcasting schedule step before broadcasting the broadcasting contents. The broadcasting contents transmission schedules to be created in the broadcasting arrangement step are created taking into consideration the main viewing target and the audience rating for each time period.

For example, among the broadcasting contents, the broadcasting service is provided in a format in which the contents are repeatedly exposed to the viewer, and the schedule for the advertisement exposure is determined in advance through the pre-auction before broadcasting. At this time, the transmission slot corresponding to the golden time or the transmission slot corresponding to before and after the program having the high audience rating may have a greater influence of the broadcasting contents provider. Therefore, in the case of broadcasters and advertisers, it is possible to efficiently utilize the transmission slots to maximize the advertisement exposure effect. Also, in case of the program which can predict the main audience of the program like the morning drama for the housewife, the advertisement of the main sight target is given by the advertisement of the main audience target before and after the program transmission, thereby enhancing the advertisement exposure effect.

However, the broadcasting viewing paradigm is changing due to the needs of the consumers who desire to watch the broadcasting at a desired time through various terminals and the broadcasting contents reproducing service regardless of time, and accordingly, The meaning is reduced and the time dependency of broadcast contents is weakened.

Therefore, it is difficult to expect as much advertising exposure as before when placing an advertisement on Golden Time. For this reason, there is a need for a method of controlling a service provided to a viewer in a flexible manner not dependent on a program transmission schedule created before broadcast transmission.

In addition, since existing broadcast services can not predict when a viewer views a broadcast service channel (or log in to a service), there is a problem that a broadcast service provider can not effectively expose broadcast content desired to be exposed, need.

In order to solve the above problems, an object of the present invention is to provide a broadcast service providing method capable of replacing broadcast contents according to a user's entry into a channel.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exemplary view for explaining a time slot concept in a time interval and a time interval in a time interval of a broadcast service according to an embodiment of the present invention. Referring to FIG.

Broadcasting contents transmitted from broadcasting service include various broadcasting programs and advertisements. At this time, since broadcast programs and advertisements are generally organized in advance according to the transmission schedule, they may be time-dependent as shown in FIG.

Here, among the time periods 11 and 12 in which the broadcast programs are arranged and the time periods 10 and 13 in which the advertisement is to be arranged, there is a so-called golden time. The golden time is a time period in which the audience rating is generally expected to be high, and may be a period in which the audience rating for a specific target audience is high.

Referring to FIG. 1, when a time interval 10 between 20:50 and 21:00 is assumed to be a golden time 10, a plurality of broadcast contents can be transmitted again in the golden time 10. For example, the time interval 10 between 20:50 and 21:00 may be a time interval during which the advertisement contents are transmitted between the program time intervals, and the advertisement time interval 10 may include a plurality of advertisements The contents A1, A2, A3, ..., A10, A11, and A12 can be sent out. Accordingly, a time period in which one broadcast content (for example, an advertisement) can be transmitted out of the time intervals through which the broadcast is transmitted can be referred to as a time slot.

According to FIG. 1, if there are broadcast contents of A1 to A12 for a time interval 10 between 20:50 and 21:00, there may be a total of 12 time slots. In this case, a period in which the auction rate is expected to be high among various time slots and auction is performed at a high cost can be referred to as a golden slot. For example, a time slot through which A12 broadcast content is transmitted may be a golden slot.

In this way, a broadcasting service may have a golden time or a golden slot depending on a time slot or a slot to be transmitted. If the broadcasting service is pre-arranged according to a programming schedule, it is difficult to expect the broadcasting service provider's intended exposure effect depending on whether the viewer is watching . Accordingly, the present invention proposes a method of replacing broadcasting contents corresponding to a part of time periods among broadcast broadcasting time periods previously organized.

FIG. 2 is an exemplary diagram illustrating a time interval during which broadcast content can be replaced in a broadcast service according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 2, it can be seen that, in a broadcast transmission schedule set according to time, a time interval in which broadcast contents can be exchanged is defined for a certain time interval.

Specifically, when the news program is preset to be transmitted in the time interval 20 between 21:00 and 21:50, since the time intervals 21 and 22 before and after the news program are expected to have a high audience rating, . Accordingly, for a time interval 21 between 20:50 and 21:00 and a time interval 22 between 21:50 and 22:00, the broadcast service provider may adaptively broadcast And can transmit a message indicating that the content can be replaced to the receiving terminal (viewer side terminal).

On the other hand, for the time interval 23 between 24:00 and 24:10, the broadcast content can not be replaced.

Here, it is a matter of how to transmit the exchangeable time interval to the receiving terminal. The broadcasting contents provider can transmit the identification information indicating the time interval in which the broadcasting contents can be exchanged to the receiving side. For example, it can be transmitted as Low Level Signaling (LLS) data or Service Layer Signaling (SLS) data of Advanced Television System Committee (ATSC) 3.0.

When it is transmitted as SLS data, it can be transmitted as an event of MPD (Media Presentation Description), for example, as follows.

<MPD>
<period>
...
<EventStream schemeIdUri = "xxx">
<Event timescale = "90000", presentationTime = "5405400" duration = "5400000">
<xx: ContentReplaceableSection id = "1" startTime = 2017-08-20T20: 50: 00 duration = 10minute endTime = 2017-08-20T21: 00: 00>
</ xx: ContentReplaceableSection>
</ Event>
</ EventStream>
</ period>
</ MPD>

Referring to Table 1, a broadcast transmission time interval that can be interchanged in MPD is defined. Specifically, '1' is defined as an identification id indicating a replaceable time interval in the ContentReplaceableSection portion, and a start time (startTime) The end time (endTime) and the duration of the time interval (duration).

The receiving terminal of the viewer can receive the MPD event message including the information indicating the replaceable time interval to determine when to replace the broadcast content.

3 is a diagram illustrating an example of a method for indicating a plurality of contents in a time interval during which broadcasting contents can be replaced in a broadcasting service according to an exemplary embodiment of the present invention.

As described above, since a plurality of broadcast contents can be transmitted again within a replaceable time period, it is necessary to transmit information indicating each of the individual broadcast contents.

For example, considering the time interval 31 between 20:50 and 21:00 among the replaceable intervals 31, 32 and 33 of the broadcast contents, it is assumed that A1 , A2, ..., A12, 12 broadcast contents (for example, advertisement) occupy a time period corresponding to 10 minutes. At this time, not all of the twelve broadcast contents are transmitted at the same time intervals, but have different time intervals for each contents, so it is necessary to transmit individual time information for the broadcast contents. Here, the method of transmitting the individual time information of the time slots within the replaceable time interval is as follows.

<MPD>
<period>
...
<EventStream schemeIdUri = "xxx">
<Event timescale = "90000", presentationTime = "5405400" duration = "5400000">
<xx: ContentReplaceableSection id = "1" startTime = 2017-08-20T20: 50: 00 duration = 10minute endTime = 2017-08-20T21: 00: 00>
<contentList>
<content id = "1" begin = "0s" dur = "20s" ... />
<content id = "2" begin = "21s" dur = "30s" ... />
<content id = "3" begin = "51s" dur = "20s" ... />
...
<content id = "12" begin = "550s" dur = "50s" ... />
</ contentList>
</ xx: ContentReplaceableSection>
</ Event>
</ EventStream>
</ period>
</ MPD>

Referring to Table 2, it can be confirmed that information (contentList) of individual broadcast contents within the corresponding time period is defined in addition to the replaceable time period information (ContentReplaceableSection) described in Table 1. Specifically, a content ID for the first broadcast content A1 to the twelfth broadcast content A12, a start time (begin) in the replaceable time interval, and a duration dur are defined Can be confirmed.

In other words, the following information can be included in the replaceable time period information in accordance with the information according to the preceding Tables 1 and 2.

Element and Attribute names Use Data type description ContentReplaceableSection 0 to N Content Replaceable Section @id One unsignedShort Identifier for the content-replaceable section @startTime One dateTime Starting point of the content changeable section @duration One dateTime Duration of content changeable interval @endTime 0 to 1 dateTime At the end of the content changeable section contentList 0 to N Content list content One Elements constituting a content list Id One unsignedShort Content identifier begin One dateTime Content start point stop One dateTime Content Duration

Referring to Table 3, the number of replaceable time interval information (ContentReplaceableSection) may exist from 0 to N according to the number of intervals to be transmitted. Each time interval information includes an identifier (id) for a content changeable interval, ), A duration, an end time, and a content list included in the corresponding time period. The content list may include an identifier (Id), a start time (begin), a duration (dur) may be included. Here, the ending time of the content replaceable section may be confirmed only by the start time and the duration, and therefore may be omitted in some cases.

4 is an exemplary diagram illustrating a broadcast content providing method considering a time point of entry of a viewer in a broadcast service according to an exemplary embodiment of the present invention.

Referring to FIG. 4, when the broadcast content A12 included in the time interval 41 between 20:50 and 21:00, which is a time interval for replacing broadcast content, belongs to the golden slot 41a, The broadcast content provider 41a belongs to a timeslot in which there is a high necessity of exposing the broadcast content provider to the viewer. 4, when the viewer enters the channel in the time interval 42 between 21:00 and 21:50 after the time slot in which the broadcast content A12 allocated to the golden slot 41a is provided There is a problem that the content A12 in the golden slot 41a is not exposed. Accordingly, there is a need for a method of replacing broadcast contents in consideration of the viewer's entry point in time.

At this time, there is a problem as to which content should be replaced when the broadcast content is replaced after the viewer enters the channel. Therefore, it is necessary for the broadcast content provider to transmit the information indicating the priority to the broadcast contents to the receiver (terminal of the viewer) have.

At this time, a method of transmitting information indicating the priority to the receiving side is as follows.

<S-TSID serviceId = "1001">
<RS bsid = "12" sIpAddr = "10.1.59.11" dIpAddr = "224.0.0.10" dport = "5100">
<LS tsi = "110" bw = "19940780" startTime = "2017-08-20T00: 00: 00Z" endTime = "2017-08-
21T23: 59: 59Z ">
<SrcFlow rt = "true">
<EFDT tsi = "110" maxTransportSize = "4456336">
<FDT-Instance FileTemplate = "aster_stream0_ $ TOI $ .m4s"/>
<File Content-Location = http: //www.example.com/tracks/track1.mp4 TOI = "12"
Content-length = "6100" Content-Type = "video / mp4" Content-Encoding = "gzip"
Content-MD5 = "+ VP5IrWploFkZWc11iLDdA ==" Priority-Tag = 0 />
</ FDT-Instance>
</ EFDT>
<ContentInfo> 0 </ ContentInfo>
...
</ LS>
</ RS>
</ S-TSID>

Table 4 is an example code that is included in the <File> element of < FDT-Instance > describing the file information of the broadcast content using Real-Time Object Delivery over Unidirectional Transport (ROUTE) transmission.

The < FDT-Instance > is used in a broadcast using a FLUTE (File Delivery over Unidirectional Transport) based transmission protocol or a communication network such as an enhanced multimedia broadcast / multicast service (eMBMS).

Referring to Table 4, as a file element in the <FDT-Instance>, a file content-location, a content-length, a content-type, a content- ), A hash value (Content-MD5), and a priority (Priority-Tag).

That is, the receiver side can receive and manage the information according to Table 4 as information on the broadcast content file when receiving the broadcast content, and in particular, can refer to the priority-tag to replace any broadcast content Can be used to determine and rearrange.

<MPD>
<period>
...
<EventStream schemeIdUri = "xxx">
<Event timescale = "90000", presentationTime = "5405400" duration = "5400000">
<xx: ServiceAddtionalInfo contentUri = http: //www.example.com/tracks/track1.mp4 priority = 0 ... />
</ Event>
</ EventStream>
</ period>
</ MPD>

Table 5 is another example of delivering information indicating the priority of broadcast contents to the receiver.

Referring to Table 5, priority information for a specific broadcast content file can be transmitted as an event stream of MPD (Media Presentation Description). Concretely, a <ServiceAdditionalInfo> element is added as a sub-element of the event element (<Event> ... </ Event>) in the MPD, and URI information (contentUri) for the broadcast content file as attribute information of the <ServiceAdditionalInfo> It can be confirmed that priority information (priority) is included.

If the method according to Table 4 is used, it may be difficult to update the priority because the priority information is transmitted to the receiver when transmitting the broadcast contents file. However, if the method according to Table 5 is used, Since the priority information is transmitted, there is an advantage that it can be transmitted to the receiving side every time the priority is updated.

Also, using the method according to Table 5, the receiver side refers to the priority information to determine whether the broadcast content having a high priority exists in the local storage on the receiver side. If the broadcast content does not exist, the URI (Or download) the corresponding broadcast content with reference to the information.

The priority information according to Table 4 or Table 5 may be transmitted to the receiver side as separate meta data and broadcast content related files and may be managed together with the broadcast content files on the receiver side to be used in reproducing the broadcast content.

Hereinafter, a method for replacing and rearranging broadcast content using priority information that can be confirmed as described above will be described.

FIG. 5 is a diagram illustrating an exemplary method of replacing broadcasting contents according to priorities after a viewer enters time in a broadcasting service according to an exemplary embodiment of the present invention. Referring to FIG.

Referring to FIG. 5, there may be a time interval 51 between 20:50 and 21:00 and a time interval 52 between 21:50 and 22:00 where the broadcast content can be replaced. The channel entry point of viewers may exist after A12 is transmitted as content belonging to the golden slot 51a. Here, since the broadcast content A12 belongs to the golden slot 51a, it corresponds to the content having the higher priority (or the content having the highest priority). B2, B3, ..., Bn belonging to the time slot in the time interval 52 of 21:50 to 22:00, which is a replaceable section of the broadcast content after the viewer's channel entry point, The broadcast content B1 whose priority is lower than A12 can be replaced with A12.

At this time, in order to be able to replace the broadcast contents, broadcast contents for replacement may be pre-cached in the local storage of the receiver side.

FIG. 6 is a diagram for explaining a method of setting priorities among broadcast contents to be replaced in a broadcast service according to an exemplary embodiment of the present invention. Referring to FIG.

Referring to FIG. 6, the time interval that the viewer first comes into contact with after entering the channel is the time interval 62 between 21:00 and 21:50. In addition, the time interval during which the broadcast content can be replaced after the viewer's entry time of the channel is the time interval 63 between 21:50 and 22:00. Here, broadcast contents B1, B2, ..., Bn according to a preset schedule may exist in the time interval 63 between 21:50 and 22:00, and as described in FIG. 5, The broadcast contents A12, P2, P4, P5, P6, and PN stored in the local storage of the receiver side may exist. However, it is not necessarily stored in the local storage in advance, and it is also possible to receive the broadcast content from the broadcast content providing server at a time when replacement is required.

Meanwhile, the broadcast contents stored for replacement are firstly allocated to the golden slot 61a belonging to the time interval 61 in which the broadcast contents can be exchanged before the viewer's entry time as in the case of A12, There is content. In addition, some of the broadcast contents (P2, P4, P5, and P6) may be viewer-tailored contents, for example, broadcast contents matching the audience age range.

Here, for example, the broadcast content A12 allocated to the golden slot 61a is arranged in the highest order, and P2, one of the viewer-tailored contents, is arranged next to the broadcast content A12 And B3, which is the highest priority broadcast content among broadcast contents according to a preset schedule, can be arranged. That is, as shown in FIG. 6, broadcasting contents composed of A12, P2, B3, P4, P5, P6 and PN sequence may be provided to the viewer instead of the broadcasting contents which have been previously scheduled from B1 to Bn. However, the priority here is exemplary and may be set differently according to the broadcasting contents provider.

7 is a diagram illustrating an exemplary method for providing customized broadcast content for individual users in a broadcast service according to an exemplary embodiment of the present invention.

The broadcast service according to an exemplary embodiment of the present invention can provide customized broadcast contents for individual viewers in consideration of the viewing history of individual viewers, user preferences, information of the receiving terminal, network capability, and the like. For example, the user's receiver may store the viewing history or terminal information, and the user preference contents may be input directly from the user, separately collected and stored, or may measure or store network availability. Accordingly, broadcast contents having a large number of times of viewing or high viewing time can be assigned a higher priority in view of the viewer's history of the viewer, and if the network availability is degraded, the image quality of specific broadcast contents received in real- It can be replaced with broadcast content pre-stored in the local repository. Therefore, the priorities of the substitute contents to be replaced with the previously scheduled contents may be different according to the viewer's viewing history and the user preference, and the selected substitute contents may be different.

For example, referring to FIG. 7, broadcast contents are provided in the order of A12, P2, B3, P4, P5, P6 and PN for the viewer A, and time slots of the broadcast contents B3 7a may replace the broadcast content B3 to provide the broadcast content A3. That is, the viewer B can provide broadcast contents in the order of A12, P2, A3, P4, P5, P6, and PN.

FIG. 8 is an exemplary diagram illustrating a broadcast content providing method considering both a channel entry and a departure time of a viewer in a broadcast service according to an exemplary embodiment of the present invention. Referring to FIG.

8, when a viewer enters a channel in a time interval 81 between 20:00 and 20:50 and a time interval 82 between 20:50 and 21:00, Quot;). &Lt; / RTI &gt; Specifically, the viewer watches up to P5 among the rearranged broadcast contents P1, P2, A3, P4, P5, P6, P7 in the time interval 82 between 20:50 and 21:00 (Or while watching P5). Then, if the viewer re-enters the time interval 83 between 21:50 and 22:00, after the reproduction of the broadcast content B2 being provided to the user at the re-entry time is completed, the broadcast contents B3 ,..., BN), the contents P6 and P7 which have not been reproduced due to the viewer's channel deviation can be selected as substitutable replaceable contents and the broadcast contents can be rearranged according to the priorities. Accordingly, it is possible to provide the user with the broadcast contents P6, B3, P7, ..., PN rearranged after the broadcast content B2 which is being reproduced.

In a broadcast service, a plurality of versions can be produced for one broadcast content as occasion demands. For example, in the case of an advertisement, a commercial film (CF) advertising the same product of the same brand may exist in a plurality of versions according to a target user or a plurality of stories. Accordingly, not only the priority information of the broadcast content but also other versions of the specific content can be managed by the receiver and provided to the user. Accordingly, even if the broadcast content of the same purpose or brand is provided, it is possible to provide a plurality of versions of the broadcast content to the user. Therefore, even if the broadcast content is continuously provided within the adjacent time interval, .

Referring to FIG. 9, the specific broadcast content P1 may include broadcast contents P1-v1, P1-v2, P1-v3, P1-v4,. At this time, the broadcast content A1 allocated to the time slot 91a located in the first time interval 91 in which the broadcast content can be replaced is replaced with the first version P1-v1 of the broadcast content P1, and the second time interval The broadcast content B10 allocated to the time slot 92a located in the third time zone 92 is replaced with the second version P1-v2 of the broadcast content P1, The content C3 can be replaced with the third version (P1-v3) of the broadcast content P1. At this time, the version of the broadcast content P1 to be replaced can be selected according to the target viewer having a high audience rating in the time slot to be replaced. The second version P1-v2 of the broadcast content P1 provided in the timeslot 92a is the main content of the broadcast content P1 in the time slot 92a located in the second time zone 92, As a main target layer.

On the other hand, in order to provide different types of broadcast contents to users, it is necessary to transmit version information of broadcast contents to a receiver. An example of the version information of the broadcast content is as follows.

Element and Attribute names Use Data type Description ContentBundle 0 to N Bundle of content versions @id One unsignedShort Identifier of the content bundle @contentListNum One unsignedShort The number of versions within the content bundle @playorder 0 to 1 String Playback order for multiple versions of content within a content bundle content 1 to N Content list @default One Boolean Whether a particular version of the content is representative @target 0 to 1 String Target layer for specific versions of content @id One UnsignedShort The specific version of the content identifier @uri 0 to 1 anyURI URI information for a specific version of content

Referring to Table 6, in the version information of the broadcast content, different versions of broadcast contents are grouped into a single content bundle, and an identifier for the content bundle, the number of versions in the content bundle, A playback order for various versions of content, and the like. Here, the reproduction order may be information defined by the receiver in the order of preset versions and reproduced (Serial) or randomly selected and reproduced.

10 is a block diagram of a broadcast transmission system for providing a broadcast service according to an embodiment of the present invention.

Referring to FIG. 10, the broadcasting contents to be broadcasted first may be stored in the broadcasting contents server. At this time, the BB content delivery server that transmits content through the broadband receives the broadcast content from the broadcast content server and delivers it to the encoder (A / V Encoder), and the encoded broadcast content can be delivered to the broadband web server have.

The BC content delivery server for transmitting the content through the broadcasting network receives the CUE message from the Service Decision Server and delivers the broadcast content according to the scheduling information to the encoder (real time A / V encoder) .

On the other hand, the service decision server can generate scheduling information by receiving time interval information and schedule information that can replace contents. At this time, when time section information capable of replacing contents in real time is input, scheduling information according to the inputted section information is transmitted to the encoder, and the encoder can transmit the newly updated MPD to the Scheduling & Signaling Server. The scheduling and signaling server delivers the MPD to the ROUTE Mux as SLS data, and when the ROUTE Mux generates the ROUTE packet, the generated packet can be delivered to the receiver via the gateway.

Data to be transmitted to the receiver in advance for service replacement (for example, priority information of broadcast contents) may be stored in a non-real time server (NRT Server) and then transferred to a ROUTE Mux.

In addition, the transmission system can receive and store data related to service use (such as viewing history, preference, user information, terminal information, etc.) from a receiver.
