BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast supplementary schedule providing apparatus and a broadcast supplement schedule providing apparatus for broadcasting a broadcast supplement schedule indicating a period during which content can be downloaded from a broadcast supplement apparatus.

In recent years, when the convergence of broadcasting and communication is progressing and the contents receiving apparatus can not normally receive the contents broadcasted from the data broadcasting apparatus, a supplementary broadcast is downloaded from the server apparatus via the communication network System is disclosed in Patent Document 1 below.

That is, if the content receiving apparatus in the broadcast supplementing system can normally receive the broadcasted content from the data broadcasting apparatus, the content can be normally reproduced.

However, depending on the state of propagation when receiving the content, the content can not normally be received, and a part of the content may be missing. In such a case, the content can not be normally reproduced.

Thus, when a part of the content is missing, the content receiving apparatus notifies the server apparatus of the missing part (non-receiving part) via the communication network.

When the server device receives the notification of the non-receiving portion of the content from the content receiving device, the server device transmits the non-receiving portion to the content receiving device via the communication network.

When the non-receiving portion of the content is downloaded from the server device, the content receiving device combines the non-receiving portion with the portion that is normally received in the broadcast to construct the complete content.

Thereby, although the content receiving apparatus can reproduce the content normally, there is a situation that the propagation situation becomes worse due to weather, for example, and the content receiving apparatus in an area can not normally receive the broadcasted content from the data broadcasting apparatus It is anticipated that a plurality of content receiving apparatuses belonging to the area will simultaneously download the content from the server apparatus. As described above, when a plurality of content receiving apparatuses start downloading contents at once, the traffic of the communication network rapidly increases, congestion of the communication network occurs, and it becomes difficult to continue normal communication. Can not be downloaded.

Therefore, in order to distribute the timing of the downloading of the contents by the plurality of contents receiving apparatuses, the plurality of contents receiving apparatuses randomly set the start timing of the downloading of the contents using the random number generator.

The program organizing device 2 organizes contents to be broadcast under the instruction of a content creator or the like and transmits a broadcast schedule indicating the broadcast time of the contents A to N to be broadcast to the contents broadcasting apparatus 3, 4 and the broadcast supplement schedule providing device 5. [

6 is an explanatory diagram showing an example of a broadcast schedule and a broadcast supplement schedule. In the first embodiment, for convenience of explanation, as shown in Fig. 6, contents A, contents B, contents C, contents D, contents E, It is assumed that a broadcast schedule for broadcasting various contents A to N is output in this order.

When receiving the broadcast schedule from the program organizing apparatus 2, the broadcast supplement schedule providing apparatus 5 refers to the broadcast schedule and causes the contents receiving apparatus 6 to transmit the contents A to N from the broadcast supplement apparatus 4 to the communication network 7), and broadcasts the schedule for the broadcast supplement.

Hereinafter, processing contents of the broadcast supplement schedule providing device 5 will be described in detail.

When the broadcast schedule is output from the program organizing apparatus 2 (step ST51 in FIG. 5), the broadcast schedule acquisition section 31 of the broadcast supplement schedule providing device 5 acquires the broadcast schedule and broadcasts the broadcast schedule And outputs it to the supplement schedule creation unit 32 (step ST52).

When receiving the broadcast schedule from the broadcast schedule acquisition unit 31, the broadcast supplement schedule creation unit 32 refers to the broadcast schedule to allow the content reception device 6 to acquire the contents A to N from the broadcast supplement apparatus 4, (Step ST53). The broadcast supplement schedule is a broadcast schedule that indicates a period during which the broadcast program can be distributed and downloaded via the Internet 7 (step ST53).

The start time of the period in which the content scheduled to be broadcast can be downloaded is after the broadcast of the content.

For example, as shown in Fig. 6, the start time of a period during which the content A can be downloaded is a time point after the start of the broadcast of the content A (after the lapse of a predetermined time from the start of the broadcast of the content A) The time period during which the content A can be downloaded is T2 time.

Therefore, the end time of the period in which the content A can be downloaded is the time point when the time T1 + T2 elapses from the start of the broadcast of the content A.

In the example of Fig. 6, in order to distribute the broadcast supplement timing of the contents A to N, the individual downloadable periods in the contents A to N are not overlapped with each other, and in a certain period, only one content can be downloaded .

When the broadcast supplement schedule is generated by the broadcast supplement schedule creation unit 32, the broadcast supplement schedule schedule broadcast unit 33 modulates the broadcast supplement schedule to broadcast waves, and transmits the broadcast supplement schedule to a plurality of (Step ST54).

When receiving the broadcast schedule from the program organizing apparatus 2, the contents broadcasting apparatus 3 refers to the broadcasting schedule, recognizes the contents A to N scheduled to be broadcast, and transmits the contents A to N to be broadcasted from the contents server 1, N is obtained.

When the contents broadcasting apparatus 3 acquires the contents A to N scheduled to be broadcasted, the contents broadcasting apparatus 3 broadcasts contents A to N scheduled to be broadcast according to the broadcasting schedule.

That is, the content broadcasting apparatus 3 modulates the content A to N scheduled to be broadcast to the broadcasting wave and transmits the broadcasting wave, thereby broadcasting the contents A to N scheduled to be broadcast to a plurality of contents receiving apparatuses 6 do.

In the example of Fig. 6, contents A, contents B, contents C, contents D, contents E, The contents A to N are broadcast in this order.

The content receiving apparatus 6 receives the broadcast supplement schedule broadcasted from the broadcast supplement schedule providing apparatus 5.

In addition, the content receiving apparatus 6 receives the content broadcasted from the content broadcasting apparatus 3.

At this time, when there is a non-receiving part that can not normally receive the content broadcasted from the content broadcasting apparatus 3, it is possible to download the content by referring to the broadcasting supplement schedule broadcasted from the broadcasting supplement schedule providing device 5 During the period, the non-received portion of the content is downloaded from the broadcast supplement apparatus 4. [

For example, when a situation occurs in which a plurality of contents receiving apparatuses 6 belonging to a certain area can not normally receive contents A, B, and C due to weather, etc., It is expected that a plurality of contents receiving apparatuses 6 will simultaneously download the contents A, B, and C from the broadcast supplement apparatus 4.

However, in the first embodiment, periods in which contents A, B, and C can be downloaded are distributed so that a situation in which a plurality of contents receiving apparatuses 6 simultaneously download contents A, B, and C does not occur .

Hereinafter, the processing contents of the content receiving apparatus 6 will be described in detail.

When the broadcast wave receiver 11 of the content receiving apparatus 6 receives the broadcast wave transmitted from the broadcast supplement schedule providing apparatus 5 (step ST31 in FIG. 3), the broadcast wave receiver 11 demodulates the broadcast supplementary schedule from the broadcast wave, And outputs the broadcast supplement schedule to the broadcast supplement schedule acquiring unit 12 (step ST32).

When the broadcast supplemental schedule is output from the broadcast wave receiver 11, the broadcast supplement schedule acquisition unit 12 acquires the broadcast supplement schedule and records the broadcast supplement schedule in an internal memory (step ST33).

Next, the broadcast wave receiver 11 demodulates the contents A to N from the broadcast wave when receiving the broadcast wave transmitted from the contents broadcasting apparatus 3 (step ST34), and stores the contents A to N as contents acquisition (Step ST35).

When the contents A to N are outputted from the broadcast wave receiver 11, the contents acquisition unit 13 acquires the contents A to N and records them in the contents recording unit 14 (step ST36).

When the contents acquisition unit 13 records the contents A to N in the contents recording unit 14, the normal reception judgment unit 15 checks the continuity of the contents for each of the contents A to N, It is determined whether or not A to N can not be normally received (step ST37).

Here, for convenience of explanation, it is assumed that contents D to N can be received normally but contents A, B, and C can not be normally received.

The determination result of the normal reception determining section 15 is output to the downloadable period specifying section 16, the download start timing determining section 19, and the content reproducing section 22. [

Thus, the contents reproducing section 22 recognizes that reproduction of the contents A, B, and C is impossible at this point of time, although it is possible to reproduce the contents D to N. For example, Do not accept the play, even if you receive an instruction. At this time, information such as the fact that the contents A, B, and C are not reproducible can be displayed on a display (not shown).

If the determination result of the normal reception determination unit 15 indicates that the contents A, B, and C can not normally be received (step ST38), the downloadable period specifying unit 16 determines whether the broadcast supplement schedule acquisition unit 12 (Step ST39), with reference to the broadcast supplement schedule recorded in the internal memory of the mobile terminal (step ST39).

In the example of Fig. 6, the point in time when the time T1 has elapsed from the start of the broadcast of the content A is the start time of the period in which the content A can be downloaded, Is the end time of the period in which it is possible to download.

It is also assumed that the time point when the time T1 + T2 has elapsed from the start of the broadcast of the content A is the start time of the period in which the content B can be downloaded and the time from the start time to the time T2 ' It is the end of the period for which downloading is possible.

It is also assumed that the time point at which the time T1 + T2 + T2 'elapses from the start of the broadcast of the content A is the start time of the period in which the content C can be downloaded, and the point in time T2 " It is the ending time of the period in which the contents C can be downloaded.

The random number generator 18 generates the random number generator 18 to generate the random number generator 18 in such a manner that a plurality of the content receiving apparatuses 6 simultaneously transmit the contents A (or the contents B and the contents C) , And generates a random value that is a random number (step ST40).

For example, the random number generator 18 of any content receiving apparatus 6 generates "X" as the random value R and the random number generator 18 of the other content receiving apparatus 6 generates the random value R as "X" And a different "Y"

When downloading the content A, for example, in the period specified by the downloadable period specifying unit 16 (the period of time T2), the download start timing determining unit 19 determines whether or not the non- The start timing of the downloading is determined according to the random value R generated from the random number generator 18 (step ST41).

For example, when the start timing Tm of the download is distributed to 10 in the period in which the content A can be downloaded, the random value R is adjusted so as to occur in the range of "0" to "9".

Then, the start timing Tm of downloading is calculated by substituting the random value R into the following equation.

Tm = T1 + T2 占 R / 10

When the content B is downloaded, the start timing of downloading of the non-received portion of the content B is set to the random number generator 18 within the period specified by the downloadable period specifying unit 16 (time period T2 ' In accordance with the random value R generated from the random number generator.

In the case of downloading the content C, the timing of starting the download of the non-received portion of the content C in the period specified by the downloadable period specifying unit 16 (the period of time T2 " In accordance with the random value R generated from the random number generator.

When the download start timing determining unit 19 determines the start timing of downloading the contents A, B, and C, the download unit 20 monitors a clock (not shown) .

The download unit 20 detects the start timing of downloading of the content A (step ST42), and identifies the identification information (program ID) of the content A and a defect in the content A through the network interface unit 17 (For example, the number of bytes from the beginning of the content A and the amount of data) indicating the part of the content A to the broadcast supplement apparatus 4 via the communication network 7 (step ST43) .

When the start timing of the downloading of the content B is detected (step ST42), the identification information (program ID) of the content B and the specifying information indicating the defective part in the content B , The number of bytes from the beginning of the content B, the amount of data, etc.) to the broadcast supplement apparatus 4 via the communication network 7 (step ST43).

When the start timing of downloading of the content C is detected (step ST42), the identification information (program ID) of the content C and the specifying information indicating the defective part in the content C , The number of bytes from the beginning of the content C, the amount of data, etc.) to the broadcast supplement apparatus 4 via the communication network 7 (step ST43).

The broadcast supplementary apparatus 4 acquires contents A to N scheduled to be broadcast from the contents server 1 and accumulates the contents A to N and acquires contents A to N from the contents reception apparatus 6 via the communication network 7 Receiving part of the content desired to be provided is specified from the identification information of the content included in the providing request and the specific information indicating the defective part in the content, And distributes the receiving section to the content receiving apparatus 6 via the communication network 7. [

The download unit 20 downloads the non-received portion of the content A (or the content B and the content C) from the broadcast supplement apparatus 4 via the network 7 via the network interface unit 17, A (or contents B, contents C) to the contents construction unit 21 (step ST44).

The content construction unit 21 receives the content A (or the content B, the content C) recorded in the content recording unit 14 when receiving the non-reception part of the content A (or the content B or the content C) C).

The content constructing unit 21 constructs the complete content by combining the normally received portion and the non-received portion of the content A (or the content B and the content C) To the content recording unit 14 (step ST45).

When the content construction unit 21 records the complete content A (or the content B or the content C) in the content recording unit 14, the content reproduction unit 22 acquires the content A (or the content B, (Or content C) is received from the content recording unit 14 at the instantaneous timing after receiving the reproduction instruction of the content A (or the content C) or when the complete content A (or the content B or the content C) , Content B, and content C), and reproduces the content A (or the content B and the content C) (step ST46).

As described above, according to the first embodiment, the contents broadcasting apparatus 3 for broadcasting the contents according to the broadcasting schedule indicating the contents broadcasting time, and the contents broadcasted from the contents broadcasting apparatus 3 to the communication network 7 A broadcast supplementary apparatus 4 for providing a broadcast schedule to the broadcast supplement apparatus 4 via the communication network 7 and a broadcast supplementary apparatus 4 for distributing one or more contents from the broadcast supplement apparatus 4 via the communication network 7 And a content supplementary schedule providing device (5) for creating a schedule and broadcasting the broadcast supplement schedule. The content reception device (6) receives the broadcast supplement schedule broadcasted from the broadcast supplement schedule providing device (5) When there is a non-reception part in which the contents broadcasted from the contents broadcasting apparatus 3 can not normally be received, the contents are referred to by referring to the broadcasting supplement schedule Since the timing for starting the downloading within the period is randomly determined and the non-received portion of the content is downloaded from the broadcast supplementing apparatus 4 in accordance with the timing, It is possible to distribute the download of a plurality of contents and to prevent the congestion of the communication network 7 from occurring.

In the first embodiment, although the download start timing determining section 19 determines that the download start timing of the non-receiving section is determined in accordance with the random value R generated from the random number generator 18, The download start timing of the content by the content receiving device 6 may be distributed or the download start timing of the content may be determined by a method other than the random value R generated from the random number generator 18. [

Specifically, the broadcast supplement schedule creation unit 32 creates a broadcast supplement schedule in the following manner.

When the content broadcasting apparatus 3 broadcasts the contents A to N at a constant transmission rate, the capacity of the contents A to N becomes larger as the broadcasting time of the contents A to N becomes longer (the broadcasting time and the capacity of the contents are proportional to each other).

In addition, the larger the capacity of the contents A to N, the greater the possibility that the amount of data when the contents receiving apparatus 6 downloads contents from the broadcast supplement apparatus 4 is high.

Therefore, when the content having a longer broadcast time and the downloadable period are lengthened, the download timing of the contents is dispersed, the amount of data flowing in the communication network 7 is averaged, and congestion of the communication network 7 can be prevented.

Therefore, the broadcast supplement schedule generation section 32 is a period during which the contents A to N can be downloaded, and sets a period of a length proportional to the broadcast time of the contents A to N. [

7 is an explanatory diagram showing an example of a broadcast schedule and a broadcast supplement schedule.

In the example of Fig. 7, the broadcast time of each content is set to be equal to the downloadable period (time T2) of each content in the broadcast supplement schedule.

Thereby, the amount of data per unit time when each content is downloaded is theoretically averaged.

In the example of Fig. 7, the time T2 is the same as the broadcast time of each content, and the timing at which each content is downloaded is not overlapped.

As described above, according to the third embodiment, it is possible to download the contents A to N when the broadcast supplement schedule creation section 32 generates the broadcast supplement schedule, It is possible to prevent the congestion of the communication network 7 at the time of downloading the content from the broadcast supplement apparatus 4. [

Embodiment 4.

In the third embodiment, it is shown that the contents broadcasting apparatus 3 broadcasts contents one by one, and the broadcasting supplement schedule is generated so that the broadcasting supplement schedule providing apparatus 5 can download the contents in a period in which they can not overlap each other However, when the content broadcasting apparatus 3 simultaneously broadcasts a plurality of contents, the broadcasting supplement schedule may be generated such that the periods in which the broadcasting supplement schedule providing apparatus 5 can download a plurality of contents overlap each other.

8 is an explanatory diagram showing an example of a broadcast schedule and a broadcast supplement schedule.

8 shows an example in which the content broadcasting apparatus 3 simultaneously broadcasts two contents. For example, the contents A and the contents M are broadcast simultaneously.

At this time, since the transmission bandwidths of the contents M to P are wider than the transmission bandwidths of the contents A to E, if the contents A and the contents M having the same broadcast time are focused on, It is expected.

However, as a period in which the broadcast supplement schedule creation unit 32 of the broadcast supplement schedule providing device 5 can download the contents A to E with reference to the broadcast schedule, And a period of time proportional to the broadcast time of the contents M to P is set as a period in which contents M to P can be downloaded.

Therefore, even if the broadcast supplement schedule is generated so that the periods in which a plurality of contents can be downloaded overlap each other, the amount of data flowing in the communication network 7 in each time period is averaged, and congestion of the communication network 7 can be prevented.

As described above, according to the fourth embodiment, when the content broadcasting apparatus 3 simultaneously broadcasts a plurality of contents, the broadcasting supplement schedule creation unit 32 of the broadcasting supplement schedule providing apparatus 5 acquires the contents Is configured so as to generate a broadcast supplement schedule so as to overlap between a plurality of contents and to set a period in which each content can be downloaded to a period of a length proportional to the broadcast time of each content , And congestion of the communication network 7 when downloading the content from the broadcast supplement apparatus 4 can be prevented.

Embodiment 5:

Although not particularly mentioned in the first to fourth embodiments, the number of the content receiving apparatuses 6 that download content from the broadcast supplement apparatus 4 is influenced by the audience rating of the content.

For example, even if the contents of the same reception condition are the same, if the audience rating is high, the number of the content receiving apparatuses 6 that download contents in the same time period increases. On the contrary, (6) becomes smaller.

Therefore, if content having a high audience rating is frequently downloaded, there is a fear that congestion of the communication network 7 will occur.

Therefore, in the fifth embodiment, by creating a broadcast supplement schedule so that a period during which a content can be downloaded overlaps between a plurality of contents (a content having a high audience rating and a content having a low audience rating) And averages the amount of data flowing in the communication network 7 in each time zone.

9 is an explanatory diagram showing an example of a broadcast schedule and a broadcast supplement schedule.

9 shows an example in which the downloadable period of the content A and the downloadable period of the content B overlap, and the downloadable period of the content C and the content D are overlapped.

In the example of Fig. 9, since the viewing rates of the contents B and D are very high and the viewing ratings of the contents A and C are low, the combination of the contents A and the contents B as the combination of the contents for duplicating the downloadable period, And the content D are combined.

The broadcast supplement schedule creation unit 32 of the broadcast supplement schedule providing device 5 downloads the contents B and D with high ratings so as not to cause the congestion of the communication network 7 Is longer than the broadcast time of each content.

For example, the time period during which the content A and the content B can be downloaded is T2 hours, which is longer than the broadcast time for the content A and the content B.

However, in order to prevent the influence on the broadcasting schedule of other contents, the time T2, which is a period in which the contents A and B can be downloaded, is shorter than the broadcasting time T3 of the sum of the contents A and the contents B. Alternatively, it is set equal to the broadcast time T3 of the sum of the content A and the content B.

T2? T3

Embodiment 6:

10 is an explanatory diagram showing an example of a broadcast schedule and a broadcast supplement schedule.

10, the content broadcasting apparatus 3 is configured to transmit the same content (for example, a predetermined period of time, for example, every 20 broadcast programs are broadcast or every 8 hours) It is possible to repeatedly broadcast a plurality of times.

In the example of Fig. 10, in the period alpha, the content A is broadcast three times, the content B is broadcast twice, and the content C is broadcast once.

The broadcast supplement schedule creation unit 32 of the broadcast supplement schedule provision apparatus 5 generates a broadcast supplement schedule in consideration of the data amount of the content, the broadcast time, the expected audience rating, and the like as in the first to fifth embodiments , And for a content broadcasted a plurality of times during a predetermined period, a period in which downloading is possible only once after the last broadcast in that period is set.

For example, in the period alpha, the content A is broadcast three times, but a period in which the content A can be downloaded only once after the third broadcast is set is set.

The broadcast supplement schedule creation section 32 sets the number of contents "6" (= 3 + 2 The total time Tα of the broadcast times of the contents A, B, and C in the period α and the download time of the contents A, B, and C The downloadable period for the contents A, B and C is set so that the total time T4 of the possible periods coincides with each other.

Tα = T4

As described above, according to the sixth embodiment, when the broadcast supplement schedule is generated by the broadcast supplement schedule creation unit 32, among the contents broadcasted during a certain period from the content broadcast apparatus 3, When the contents are included, the period of time during which the contents to be broadcasted plural times can be downloaded and the total time of the period in which the contents to be broadcast only once can be downloaded are broadcasted from the contents broadcasting apparatus 3, It is possible to solve the temporal deviation of the amount of data when downloading the content from the broadcast supplement apparatus 4, and consequently, the congestion of the communication network 7 can be prevented.
