Is optional. For example, the clock 221 may be an RTC (Real Time Clock) provided outside the central processing unit 22.

  FIG. 3 shows a specific configuration example of the distributor terminal 3. The distributor terminal 3 includes a communication unit 31, a central processing unit 32, a storage unit 33, a data storage unit 34, a nonvolatile memory 35, a camera 36, a microphone 37, a display unit 38, and an operation unit 39. The communication unit 31 communicates with the streaming data distribution server 2 via the network 1. The storage unit 33 is a non-transitory storage medium, and the storage unit 33 stores a distributor terminal control program for controlling the distributor terminal 3.

  The data storage unit 34 can be configured by a VRAM. The nonvolatile memory 35 is, for example, an EEPROM (Electrically Erasable Programmable Read Only Memory), and stores identification information of the distributor terminal 3. The operation unit 39 is a touch panel arranged on the screen of the display unit 38 as an example. The operation unit 39 may be an operation button.

  The central processing unit 32 executes a distributor terminal control program. As a result, the central processing unit 32 has, as functional configurations, an operation detection unit 321, an operation signal transmission unit 322, an instruction signal reception unit 323, an on-screen display (OSD) control unit 324, a data compression unit 325, and data transmission control. Part 326.

  The operation detection unit 321 detects an operation by the operation unit 39. The operation signal transmission unit 322 transmits an operation signal in response to the operation by the operation unit 39 detected by the operation detection unit 321 to the streaming data distribution server 2 via the communication unit 31 and the network 1. When the distributor terminal 3 applies to the streaming data distribution server 2 as the distributor terminal 3 that distributes the streaming data, the operation signal transmission unit 322 transmits the information of the distributor terminal 3 stored in the nonvolatile memory 35.

  The instruction signal receiving unit 323 receives an instruction signal from the distributor terminal instruction unit 224 of the streaming data distribution server 2. The OSD control unit 324 superimposes on-screen information on the moving image output from the camera 36 in response to the instruction signal. On-screen information is characters, symbols or images. The OSD control unit 324 may superimpose on-screen information on the moving image according to the operation by the operation unit 39 detected by the operation detection unit 321.

  The moving image output from the camera 36 is supplied to the display unit 38 via the OSD control unit 324 and displayed. The data compression unit 325 compresses and encodes the moving image output from the camera 36 into a predetermined format while temporarily storing the moving image in the data storage unit 34. The data compression unit 325 can adopt an arbitrary compression format such as H.264 / MPEG-4 AVC, H.265 / HEVC, or the like, as a moving image compression format.

  The data transmission control unit 326 generates streaming data in which the information of the distributor terminal 3 stored in the nonvolatile memory 35 is added to the compressed moving image and the compressed audio output from the data compression unit 325, and the communication unit 31. To control the transmission to the streaming data distribution server 2.

  Here, the operation detection unit 321 to the data transmission control unit 326 are configured by software. However, the operation detection unit 321 to the data transmission control unit 326 may be configured by hardware such as a circuit, or may be a mixture of software and hardware. Is optional.

  The distributor terminal 3 may distribute streaming data including moving images and audio as actual data distributed to the viewer terminal 4, or may distribute streaming data including only moving images, or audio. Streaming data including only may be distributed. When the distributor terminal 3 distributes streaming data including only moving images, the microphone 37 can be omitted. When the distributor terminal 3 distributes streaming data including only audio, the camera 36 can be omitted.

  FIG. 4 shows a specific configuration example of the viewer terminal 4. The viewer terminal 4 includes a communication unit 41, a central processing unit 42, a storage unit 43, a data storage unit 44, a nonvolatile memory 45, a display unit 46, an operation unit 47, and a speaker 48. The communication unit 41 communicates with the streaming data distribution server 2 via the network 1. The storage unit 43 is a non-temporary storage medium, and the storage unit 43 stores a viewer terminal control program for controlling the viewer terminal 4.

  The data storage unit 44 can be configured by a VRAM. The nonvolatile memory 45 is, for example, an EEPROM, and stores identification information of the viewer terminal 4. The operation unit 47 is a touch panel arranged on the screen of the display unit 46 as an example. The operation unit 47 may be an operation button. The display unit 46 displays the distributed moving image, and the speaker 48 outputs the distributed sound.

  When the central processing unit 42 executes the viewer terminal control program, the central processing unit 42 has, as a functional configuration, an operation detection unit 421, an operation signal transmission unit 422, a data decompression unit 423, an on-screen display (OSD). A control unit 424 is provided.

  The operation detection unit 421 detects an operation by the operation unit 47. The operation signal transmission unit 422 transmits an operation signal in response to the operation by the operation unit 47 detected by the operation detection unit 421 to the streaming data distribution server 2 via the communication unit 41 and the network 1. When the viewer terminal 4 applies to the streaming data distribution server 2 as the viewer terminal 4 that receives the distribution of streaming data, the operation signal transmission unit 422 transmits information on the viewer terminal 4 stored in the nonvolatile memory 45. .

  The data decompression unit 423 decompresses the compressed moving image included in the streaming data distributed from the streaming data distribution server 2 while temporarily storing the compressed moving image in the data storage unit 44, and supplies the decompressed moving image to the OSD control unit 424. The data decompression unit 423 decompresses the compressed audio included in the streaming data while temporarily storing it in the data storage unit 44 and supplies the decompressed voice to the speaker 48. The data decompression unit 423 decompresses the compressed moving image and the compressed audio corresponding to the compression format in the data compression unit 325.

  The OSD control unit 424 may superimpose on-screen information on the moving image according to the operation by the operation unit 47 detected by the operation detection unit 421. The moving image output from the OSD control unit 424 is supplied to the display unit 46 and displayed.

  Here, the operation detection unit 421 to the OSD control unit 424 are configured by software. However, the operation detection unit 421 to the OSD control unit 424 may be configured by hardware such as a circuit, and the software and hardware may be mixed. Is optional.

  When the streaming data to be distributed includes only a moving image, the speaker 48 can be omitted. When the streaming data to be distributed includes only audio, the display unit 46 can be omitted.

  Next, taking a soccer game as an example of an event to be photographed, an explanation will be given of how a soccer game is filmed and distributed to the viewer terminal 4 using the streaming data distribution system shown in FIG. . Here, the distribution of moving images will be described as an example. For simplification, it is assumed that the distributor terminal 3 includes three distributor terminals 3a to 3c.

  As shown in FIG. 5, the distributor terminal 3a is located on the second floor of the main stand 100M of the stadium 100, and the distributor terminals 3b and 3c are located on the first floor of the back stand 100B. To do. Distributor terminal 3b is located approximately in the center of goals 103a and 103b, and distributor terminal 3c is located relatively close to goal 103b. The distributor terminals 3a to 3c shoot a game played at the pitch 102.

  FIG. 6 illustrates a first example of a selection method in which the distribution data selection determination unit 226 illustrated in FIG. 2 selects a moving image to be distributed to the viewer terminal 4 from moving images transmitted from the distributor terminals 3a to 3c. Is shown conceptually.

  As shown in FIG. 6A, the distributor recruitment control unit 222 distributes moving images to a plurality of distributor terminals 3 registered in advance during the recruitment period from time t1 to t2. Recruit terminal 3. As shown in FIG. 8, the distributor terminal instruction unit 224 instructs the distributor terminals 3 a to 3 c to display a distribution application button 381, for example, “Delivery request”. The instruction signal receiving unit 323 of the distributor terminal 3 receives an instruction from the distributor terminal instruction unit 224 and instructs the OSD control unit 324 to display the distribution application button 381 on the display unit 38.

  As shown in FIG. 6B, it is assumed that the distributor terminal 3b and the distributor terminal 3a have applied in this order during the recruitment period from time t1 to t2. The upward arrows shown in (b) of FIG. 6 and (b) of FIG. 7 to be described later conceptually indicate the timing when the distributor terminal 3 applied.

  Specifically, when the distributor having the distributor terminals 3 a and 3 b operates the distribution application button 381, the operation signal transmission unit 322 transmits an operation signal indicating that an application has been made to the streaming data distribution server 2. The operation signal includes identification information of the distributor terminal 3. The operation signal is input to the distribution data selection determination unit 226.

  In the first example, the distribution data selection determination unit 226 selects one distributor terminal 3 that distributes moving images by lottery with the distributor terminals 3a and 3b that have applied. Here, it is assumed that the distributor terminal 3a is selected as a result of the lottery and is determined to be the distributor terminal 3 that distributes the moving image.

  The selection data distribution unit 227 instructs the writing / reading control unit 225 to read out the moving image from the distributor terminal 3a among the moving images from the distributor terminals 3a to 3c stored in the data storage unit 24. As shown in FIG. 6C, the selected data distribution unit 227 distributes the moving image read from the data storage unit 24 from the distributor terminal 3a to the viewer terminal 4 only during the period from time t3 to t6. To do.

  In FIG. 6C and FIG. 7C described later, a hatched period indicates a period during which the viewer terminal 4 is distributed. The time for which the selected distributor terminal 3 distributes the moving image is a fixed time such as 1 minute or 2 minutes.

  The distributor terminal instructing unit 224 instructs the distributor terminal 3 that has determined the distributor terminal 3 that distributes the moving image to display that the distributor terminal 3 that distributes the moving image has been selected. . Upon receiving the instruction, the OSD control unit 324 of the distributor terminal 3 causes the display unit 38 to display, for example, a mark 382 written as “distributing” instead of the distribution application button 381 as shown in FIG.

  Instead of displaying the mark 382, the color or brightness of the distribution application button 381 may be varied. It is only necessary that the distributor can recognize whether or not the distributor terminal 3 of the distributor is selected as the distributor terminal 3 that distributes the moving image.

  As shown in FIG. 6A, the distributor recruitment control unit 222 sets the recruitment period again at times t4 to t5 before the time t3 to t6 when the moving image from the distributor terminal 3a is distributed ends. Set and recruit distributor terminals 3 who want to distribute moving images. At this time, the distributor terminal instructing unit 224 instructs the distributor terminal 3a selected in the last lottery to make the distribution application button 381 inactive as shown in FIG. It is preferable that the detection unit 321 invalidates the operation of the distribution application button 381.

  In this way, a distributor having the distributor terminal 3a selected in the immediately preceding lottery can recognize that his distributor terminal 3a cannot apply as a distributor terminal 3 for distributing moving images. . Instead of making the distribution application button 381 inactive, the distribution application button 381 may be deleted. What is necessary is just to set suitably how long the distributor terminal 3 selected as the distributor terminal 3 that distributes the moving image should not be applied for (for how many lottery times).

  As shown in FIG. 6B, it is assumed that the distributor terminal 3c and the distributor terminal 3b have applied in this order during the recruitment period from time t4 to t5. The distribution data selection determining unit 226 determines one of the distributor terminals 3 that distributes moving images by lottery at the distributor terminals 3b and 3c that have applied. Here, it is assumed that the distributor terminal 3b is selected as a result of the lottery and is determined to be the distributor terminal 3 that distributes the moving image.

  As shown in FIG. 6C, the selected data distribution unit 227 distributes the moving image from the distributor terminal 3b read from the data storage unit 24 to the viewer terminal 4 after time t6.

  Here, at least the distributor terminal 3 selected in the previous lottery is excluded from the distributor terminals 3 that can be applied, but it is possible to apply regardless of whether or not it has been selected as a distributor terminal 3 that distributes moving images in the past. As an example, the distribution data selection determination unit 226 may draw lots at all the distributor terminals 3 that have applied. When the number of distributor terminals 3 is large, the possibility that the same distributor terminal 3 is continuously selected becomes low, so that there is almost no problem.

  FIG. 7 conceptually illustrates a second example of a selection method in which the distribution data selection determination unit 226 selects a moving image to be distributed to the viewer terminal 4.

  As shown in (a) of FIG. 7, the distributor recruitment control unit 222 is a distributor who wishes to distribute moving images to a plurality of distributor terminals 3 registered in advance during the recruitment period from time t1 to t2. Recruit terminal 3. As shown in FIG. 7B, it is assumed that the distributor terminal 3b and the distributor terminal 3a have applied in this order during the recruitment period from time t1 to t2.

  In the second example, the distribution data selection determining unit 226 determines the distributor terminal 3 that has applied for the earliest after time t1, which is the start time of the recruiting period, as the distributor terminal 3 that distributes moving images. Here, the distributor terminal 3b is selected. As shown in (c) of FIG. 7, the selection data distribution unit 227 distributes the moving image from the distributor terminal 3b read from the data storage unit 24 to the viewer terminal 4 only during the period from time t3 to t6. To do.

  As shown in (a) of FIG. 7, the distributor recruitment control unit 222 again sets the recruitment period at time t4 to t5 before the time t3 to t6 when the moving image from the distributor terminal 3b is distributed ends. Set and recruit distributor terminals 3 who want to distribute moving images. As shown in FIG. 7B, it is assumed that the distributor terminal 3c and the distributor terminal 3a have applied in this order during the recruitment period from time t4 to t5. The distribution data selection determination unit 226 determines the distributor terminal 3c that applied the earliest after time t4, which is the start time of the recruiting period, as the distributor terminal 3 that distributes the moving image.

  As shown in (c) of FIG. 7, the selection data distribution unit 227 distributes the moving image from the distributor terminal 3 c read from the data storage unit 24 to the viewer terminal 4 after time t6.

  Also in the second example, it is preferable to exclude at least the distributor terminal 3 selected in the previous lottery from the distributor terminals 3 that can be applied.

  In the second example, the distributor terminal instruction unit 224 may instruct the distributor terminal 3 to display a countdown on the display unit 38 in order to notify the distributor of the start of the recruitment period. In the second example, the recruitment period may be shorter than the application period in the first example.

  In the example shown in FIGS. 6 and 7, the recruitment periods are set discretely, but the recruitment periods may be set continuously. When the distributor terminal 3 that distributes the moving image is recruited and one distributor terminal 3 is selected, the moving image from the selected distributor terminal 3 may be distributed to the viewer terminal 4 as soon as possible.

The distribution data selection determination unit 226 may select the distributor terminal 3 based on the user attribute included in the distributor identification information. When there are a premium member and a regular member as a distributor category, the distribution data selection determination unit 226 may increase the frequency with which the distributor terminal 3 of the premium member is selected. The distribution data selection determination unit 226 may vary the frequency with which the distributor terminal 3 is selected depending on the length of the member registration period of each distributor. Typically, the longer the member registration period, the higher the frequency of selection. However, the frequency with which a new member is selected may be particularly increased.

  The streaming data distribution server 2 may charge the distributor terminal 3 and vary the frequency with which the distributor terminal 3 is selected according to the amount paid by the distributor terminal 3. When the viewer terminal 4 is registered corresponding to each distributor terminal 3, the frequency with which the distributor terminal 3 is selected may be varied depending on the number of registered viewer terminals 4. The viewer terminal 4 selects the distributor terminal 3 to be distributed and pays the streaming data distribution server 2, and the streaming data distribution server 2 responds to the amount for each distributor terminal 3 paid by the viewer terminal 4. The frequency with which the distributor terminal 3 is selected may be varied.

  The distribution data selection determining unit 226 may be configured to select the first example shown in FIG. 6 and the second example shown in FIG. When there is a period during which no distributor terminal 3 applies, any one of the distributor terminals 3 registered in the distributor terminal information holding unit 223 may be arbitrarily selected and the distributor terminals 3 may be switched in order.

  FIG. 11 shows an example in which moving images transmitted from the distributor terminals 3a to 3c are selected and distributed with the progress of time. In FIG. 11, the streaming data distribution server 2 distributes the streaming data SD3a generated by the distributor terminal 3a to the viewer terminal 4 until time t11. Each rectangle in the streaming data SD3a to SD3c represents one frame of a moving image to be transmitted.

  Assume that the distributor terminal 3b closer to the pitch 102 has applied for and selected the lottery before time t11. The streaming data distribution server 2 distributes the streaming data SD3b generated by the distributor terminal 3b to the viewer terminal 4 during the period of time t11 to t12. Assume that the distributor terminal 3c closer to the goal 103b is applied for and selected for the lottery within the period from time t11 to t12. The streaming data distribution server 2 distributes the streaming data SD3c generated by the distributor terminal 3c to the viewer terminal 4 after time t12.

  According to the streaming data distribution server 2 and the streaming data distribution method of the present embodiment described above, each distributor thinks that his / her distributor terminal 3 should take an important scene and distribute it to the viewer terminal 4. Apply to the distributor terminal 3 that distributes streaming data at the timing. Therefore, according to the streaming data distribution server 2 and the streaming data distribution method of the present embodiment, a moving image obtained by photographing an important scene for photographing an event to be photographed can be automatically obtained without an operator operating the switcher. Can be selected and distributed.

  In addition, according to the streaming data distribution server 2 and the streaming data distribution method of the present embodiment, the distributor is given editing authority for moving images taken by a plurality of distributor terminals 3, so content that is more attractive than expected is provided. It may be created.

  Next, modified examples of the streaming data distribution server 2 and the distributor terminal 3 will be described. The distributor terminal 3 may include a plurality of cameras 36 and may be configured to transmit a plurality of moving images captured by the plurality of cameras 36 to the streaming data distribution server 2.

  FIG. 12 shows a configuration example of the distributor terminal 3 including a plurality of cameras 36. The distributor terminal 3 shown in FIG. 12 includes a main camera 36M and a sub camera 36S. For example, the main camera 36M is an external camera that can capture a high-resolution moving image, and the sub camera 36S is a built-in camera that captures a lower-resolution moving image than the main camera 36M. In FIG. 12, the illustration of the microphone 37 is omitted.

  In FIG. 12, the data compression unit 325 generates a compressed moving image by compressing the main moving image from the main camera 36M and the sub moving image from the sub camera 36S. The data transmission control unit 326 controls to transmit the streaming data including the main compressed moving image and the streaming data including the sub compressed moving image to the streaming data distribution server 2.

  The central processing unit 32 includes a camera selection unit 327 as a functional configuration.
