SUMMARY OF THE INVENTION The present invention relates to a CM broadcasting system for broadcasting a CM between karaoke performances in karaoke program broadcasting. It has the following features. That is, a CM data storage unit that stores video and audio data of a plurality of CMs (hereinafter referred to as CM data) is provided, and the broadcasting order of the plurality of CMs is determined by the broadcasting order determination unit and is determined. Based on the broadcasting order, the CM output means sequentially reads out the CM data of those CMs from the CM data storage means and outputs this for broadcasting. Here, the number of times of broadcasting in a predetermined period is assigned to each CM, and the broadcasting order determining means determines the number of times of broadcasting allocation and the number of CMs whose broadcasting has already ended within the period. The broadcast order of those CMs is determined based on the number of broadcasts.

According to the CM broadcasting system as described above,
The broadcasting order determining means automatically determines the broadcasting order of each CM, and the CM output means outputs the CM data of each CM for broadcasting based on the determined broadcasting order. The effort of order determination can be saved. In addition, the broadcasting order determining means is used for each CM within the period.
CMs based on the number of broadcast allocations and the actual number of broadcasts of each CM that has already been broadcast within the period.
Since the broadcasting order of the CM is determined, fairness can be ensured for the CM broadcasting frequency.

Next, the broadcast order determining means may determine the broadcast order of the CMs by using the fact that the same type of CMs are not continuously broadcast as a criterion for determining the order. This makes it possible to correct the unfairness in which the same CM is continuously broadcast.

Further, the broadcasting order determining means sets the standard broadcasting time of each CM to be different from the broadcasting time of the previous day on the basis of the broadcasting time of the previous day of each CM, as one criterion for the order determination.
The order of broadcasting the CMs may be determined. This makes it possible to correct the unfairness in which the same CM is broadcast every day in the same time zone.

Further, the broadcasting order determining means determines the broadcasting order of the CMs by determining whether or not the required broadcasting time of each CM matches the CM broadcasting time generated between the karaoke programs, as a criterion for determining the order. Can be decided. By doing this, it is possible to efficiently select a CM that falls within the CM broadcast time frame.

The storage device 9 is composed of a hard disk device, a magneto-optical disk device or the like, and a CM data storage unit 10 (CM data storage means) thereof has a plurality of Cs.
M video and audio data (CM data) is stored in association with the CM number. In the CM ranking determination data storage unit 11, as shown in FIG. 2, the broadcast contract period 11c and the number of broadcasts 11d of each CM (the number of broadcast contracts within the period 1
1f and the current number of broadcasts 11e), the last broadcast time 1
Each data for determining the broadcasting order such as 1 g, the broadcasting time of the previous day (or each broadcasting time in the case of being broadcast a plurality of times) 11 h, the broadcasting time 11 i (hereinafter collectively referred to as CM ranking determination data Is called CM number 11a
Is stored in association with, and the content is updated whenever the CM is broadcast.

Returning to FIG. 1, a karaoke device 12 is connected to the I / O port 2. As shown in FIG. 3, the karaoke device 12 includes a CPU 21, a ROM 22, and a RAM 23.
And a karaoke data storage device 24 such as a hard disk device connected to the karaoke control unit 20, an input unit 28 such as a keyboard for selecting a performance song, a tone synthesis unit 29 including a synthesizer, and the like. The image synthesis control unit 30 and the like are provided. Further, a signal multiplexer 31 is connected to the musical sound synthesizer 29 and the image synthesis controller 30. That is, when the music number of the performance music is input from the input unit 28, the musical tone data 25, the lyrics data 26 and the background video data 27 of the corresponding performance music are read from the karaoke data storage device 24. The musical tone synthesizing unit 29 generates a musical tone signal of the musical composition based on the read musical tone data 25. On the other hand, the video composition control unit 30 generates a video signal of the lyrics telop based on the lyrics data, and further superimposes the video signal on the background video signal based on the background video data 27 to form a composite video signal. Then, the performance sound signal and the synthesized video signal are multiplexed by the signal multiplexer 31, and the multiplexed signal is broadcast by the broadcast transmitter 13 (FIG. 1).

Further, in FIG. 1, the I / O port 2 has D / A converters 14 and 1 for converting the audio data and the video data from the CM data storage unit 10 into analog data.
5 and a signal multiplexer 16 that multiplexes the analog signals output from them are connected. The multiplexed audio and video signal from the signal multiplexer 16 is broadcast by the broadcast transmitter 13.

Next, in the ROM 4, a broadcast order determination program 4a for determining the broadcast order of the CM based on the CM order determination data described above, and CM data of the CM to be broadcast according to the determined order. A CM output control program 4b for sequentially reading out from the data storage unit 9 and outputting it is stored. Further, the RAM 5 is formed with a rank determination table memory 5a for storing a rank determination table (FIG. 4, which will be described later) for performing the rank determination calculation based on the CM rank determination data.

The operation of the CM broadcasting system 1 will be described below with reference to a flowchart. As shown in FIG. 5, the CM broadcasting system 1 is in a CM output standby state while the music performance is being broadcast by the karaoke apparatus 12 (S1), and the music performance is completed (or the remaining time until the completion is predetermined. When the value becomes equal to or less than the value), the signal from the karaoke device 12 side is received, and the CM output process of S3 is started. And CM
When the output process ends, the process returns to S1 and the same process is repeated.

FIG. 6 is a flowchart showing details of the CM output process. That is, in S10, the next CM broadcast frame time (CM broadcast time) W is input from the input unit 8. Then, in S11, the number of remaining broadcasts N1 of each CM within the contract period is calculated as a difference between the number of broadcast contracts 11e and the number of actual broadcasts 11f of FIG. Here, the higher the value of N1, the higher the priority of the broadcast. Hereinafter, a parameter such as N1 that is used as a reference for determining the broadcast order of CM will be referred to as a reference parameter. The reference parameters used in this embodiment are variables that take positive values.

Next, in S12, the number of remaining broadcasts N1
CM numbers 11a are sorted in ascending order, and rank numbers R1 (= 1, 2, ...) Are given in the sorted order. Here, it means that the CM having a higher order number R1 has a higher priority of broadcasting. Then, the value of R1 is transferred to the rank determination table (FIG. 4) of the RAM 5, and the priority parameter P set for each CM there.
(Initial value = 0) is added.

Then, in S13, CM number 1 of each CM
1a is sorted in the new order of the last broadcast time 11g, the order number R2 (= 1, 2, ...) Is given in the sorted order, and the value of R2 is added to the priority parameter P described above. In this case, the older the last broadcast time 11g is (the larger R2 is), the more the broadcast is prioritized. Here, it can be seen that the difference B between the current time and the last broadcast time is the reference parameter.

Further, in S14, the value of the broadcasting time zone compatibility parameter F of each CM is calculated. This F is defined by the following equation 1.

[0020]

(Equation 1)

In Equation 1, N is the number of times the CM was broadcast the day before, and Ti is the time of each broadcast. Also,
T0 is today's current time. That is, | Ti-T0 |
If the value of is small, it means that the CM was broadcasted at a time relatively close to T0 on the previous day. For example, if the broadcasting time Ti of the previous day is 17:30 and the broadcasting time T0 of today is 19:00, | Ti-T0 | is 1:30 (1
30 minutes). F is an average value, that is, an index that reflects how close the CM was broadcasted on the previous day at an average time T0.

Then, proceeding to F15, the CM number 11a is sorted in ascending order of F with the above F value as a reference parameter, and the order number R3 (= 1, 2,
...) is added and the value of R3 is added to the above-mentioned priority parameter P. That is, a CM having a larger value of F (value of R3), in other words, a CM having a larger average gap time between the broadcasting time on the previous day and the current time has a higher broadcasting priority.

At this point in time, as shown in FIG. 4, the priority parameter P has been added with the values of the three rank numbers R1 to R3. That is, P is the number of remaining broadcasts N1 within the contract period, the difference B between the previous broadcast time and the current time, the average distance F from the broadcast time on the previous day,
It is an index that comprehensively reflects the contributions from the three reference parameters, and it can be said that the higher the value of P, the higher the priority of the final broadcast. And S16
In, the CM numbers are sorted in descending order of P, and the sorting order k (= 1, 2, ...) Is determined as the final priority broadcasting order. For CMs with the same P value,
For example, it is possible to set that the CM number having a smaller number is prioritized. Further, the respective order numbers R1 to R3 are arranged in order from the one having the lowest broadcasting priority, but they may be arranged in the reverse order. In this case, the smaller the value of P, the higher the priority of broadcasting. In the following description, the case of arranging from the one with the lowest priority is represented.

Then, in S19, the broadcasting time Q of the CM with k = 1 (broadcasting time 11i, FIG. 2) is compared with the broadcasting frame time W input in S10 (S17, S18), and if W ≧ Q. For example, the CM data of the CM is read and output (S1
9, S21). On the other hand, when W <Q, the broadcast of the CM is abandoned, and the same comparison is performed for the CM of the next rank (= k + 1). This process is a CM that fits within the broadcast frame time W.
It is repeated until is found, and when it is found, the CM
CM data of is output. In this way, when the CM data is output, the CM ranking determination data is updated, the value of the priority parameter P is cleared, and the CM output process ends (S22, S23).

As the reference parameter, it is possible to add a parameter other than the above, or replace the reference parameter other than the remaining broadcast number N1 with another parameter. As a standard parameter that can be adopted, for example, when the broadcast time zone (or the broadcast date) is specified,
The difference D between the designated broadcast time zone and the current time (the smaller D is, the higher priority is given to the broadcast), the remaining time TR until the end of the contract period (the smaller the TR is, the higher priority is given), etc. . In any case, if the CMs are prioritized based on the size of the reference parameter, the CMs are arranged in order from the one with the lowest priority, and the order number Rx is given, and the Rx is added to P. Good.

Further, the order numbers R1, R2, ... Of each reference parameter are added to P as they are, but the contribution of each reference parameter to P depends on the importance in determining the priority order. You can make a difference. Specifically, for each rank number R1, R2, ...
Multiply by 1, n2, ... and add (that is, P =
(n1 × R1 + n2 × R2 + ...), and the value of the importance coefficient may be set larger (or smaller) as the importance becomes larger.

On the other hand, in the above embodiment, the order numbers R1, R2, ... Are added to P, but instead of the order numbers, for example, the order numbers may change in proportion to the absolute value of each reference parameter. You may make it add the numerical value defined in. For example, if the value of a certain reference parameter is X, its maximum value is Xmax, and its minimum value is Xmin, C = (X-Xmi
n) / (Xmax-Xmin), or each numerical value C and C'defined by C '= 1-C can be adopted. In this case, if the reference parameter X has a larger value, the broadcast is given priority, and if the reference parameter X has a smaller value, the broadcast is given priority. Also in this case, the value of C or C'may be multiplied by the above-mentioned importance coefficient and added.

It should be noted that, among general broadcast programs other than karaoke programs, there are quite a few CM broadcast time frames that are not constant. For example, in a sports broadcast program such as a professional baseball broadcast, C
It is necessary to fluidly set the broadcasting time frame of M. The CM broadcasting system of the present invention is premised on being applied to a karaoke broadcast program, but a CM based on the same principle.
It is not impossible to apply the broadcasting system to broadcast programs other than the above-mentioned karaoke programs. The type of broadcasting to which the present invention can be applied may be wired broadcasting or wireless broadcasting.
