FIG. 8 shows a flowchart of the data reception unit 210 of the data distribution acquisition device 200 when the digital display data a is received from the data distribution transmission device 100.
When the data distribution acquisition device 200 starts operation, in step S1, it is determined whether or not the data receiving unit 210 has received the digital display data a. If NO, the process returns to the beginning, repeats this operation, and waits for reception of digital display data. If YES, the digital display data a is stored in the received data holding memory 260. Next, in step S3, it is determined whether reception is completed. If reception is not completed, the process returns to step S1 and continues reception. When the reception is completed, the process proceeds to step S4, data analysis processing is performed, this flow is terminated, and the process returns to step S1. The data analysis process will be described in detail with reference to FIG.

FIG. 9 shows a flowchart of the data analysis processing unit 230.
When the data analysis processing unit 230 receives the data analysis instruction b in step S4, the attribute of the digital display data is determined in step S11. The attribute determination of the digital display data will be described in detail with reference to FIG. In step S12, it is determined whether or not digital display data is to be displayed as a result of the attribute determination. When it is determined that the attribute determination result is displayed (YES), the process proceeds to step S13, and the video data composition processing unit 340 is reset. This reset process will be described later with reference to FIG. Next, in step S14, the display area of the broadcast video data d is taken out, and the XY coordinates of the head position and the XY coordinates of the end position are set as shown in FIG. For example, the entire display screen is set as follows.

Disp_sx ← TVSX.POS * Panel_W / TVSX.MAX
Disp_sy ← TVSY.POS * Panel_H / TVSY.MAX
Disp_ex ← TVEX.POS * Panel_W / TVEX.MAX
Disp_ey ← TVEY.POS * Panel_H / TVEY.MAX
Next, in step S15, 1 is entered in the counter k of the data analysis processing unit 230, and it is determined in the next step S16 whether or not it is the kth display content f. If it is k-th data, the process proceeds to step S17, and in order to set information of the k-th display content f, processing for setting a display area and processing for setting the address of the k-th display content f are performed.

The process for setting the display area is, for example, as follows.
DATA_sx [k] ← CSXk.POS * Panel_W / CSXk.MAX
DATA_sy [k] ← CSYk.POS * Panel_H / CSYk.MAX
DATA_ex [k] ← CEXk.POS * Panel_W / CEXk.MAX
DATA_ey [k] ← CEYk.POS * Panel_H / CSEk.MAX
The process of setting the address and display time of the kth display content f is, for example, as follows.
DATA_adrs [k] ← Address of the searched kth display content f
Time [k] ← Display time of the searched k-th display content f

  The next step S18 instructs the data expansion process for the kth display content f. That is, the number of display contents to be displayed is set to k (DATA_count ← k). In step S19, the counter k is incremented by one (that is, (k = k + 1)). Then, it returns to step S16 and repeats the flow of steps S16-19.

If it is determined in step S12 that the digital display data a is not displayed (NO), the process proceeds to step S20. In step S20, the video data composition processing unit 240 is reset. This reset process is the same as step S13, and will be described later with reference to FIG. Next, in step S21, processing for setting the entire screen area of the display device as the display area of the broadcast video data d is performed. That is, it is as follows.
Disp_sx ← 0 Disp_sy ← 0
Disp_ex ← Panel_W-1 Disp_ey ← Panel_H-1
Disp_W ← Panel_W Disp_H ← Panel_H
Next, in step S22, processing for not displaying the digital display data a is performed. In step S23, display processing of the display device 250 is performed, and this flow ends. The display process of the display device 250 in step S23 will be described with reference to FIG.
In step S16, when there is no kth data, the process proceeds to step S23.

FIG. 10 is a flowchart for explaining in detail the data attribute determination in step S <b> 11, and shows a flowchart executed in the data analysis processing unit 230.
First, in the first step S31, the attribute of the data distribution acquisition device 200 is stored in the memory A of the display device attribute storage unit 231. In other words, (1) area name information, (2) installation location information, (3) industry information, (4) user information (note that guidance information, contact information and caution information are content information, and time information is separate. Therefore, the data distribution acquisition apparatus 200 selects and stores attribute information for selecting display content to be displayed. Alternatively, attribute information may be input from a personal computer and stored.

  In step S32, the head attribute data (attribute shown in FIG. 5B) included in the digital display data a is stored in the memory B of the data analysis processing unit 230. In step S33, the memory A and the memory B are ANDed. Next, in step S34, it is determined whether or not the result of step S33 is 0. If not, the digital display data a needs to be displayed on the data distribution acquisition device 200 in step S35. However, when it is 0, since it is not displayed by the data distribution acquisition device 200 in step S36, this flow is ended.

FIG. 11 is a flowchart for explaining in detail the reset processing of the video data composition processing unit 240 in steps S13 and S20.
Step S41 is a process of stopping the display of the display device 250. Step S42 is a process of clearing the broadcast video memory 223 and the data development memory 269 shown in FIG. Step S43 is a process of deleting the data expansion expanded in the data expansion processing units 261 to 26n by the count number of data. Next, step S44 is a process for setting the data count to 0, and then this flow is terminated.

FIG. 12 is a flowchart illustrating in detail the display process in step S23 described in FIG.
First, in step S51, the current time is set in Stime of the display device 250. In step S52, video data composition processing is performed. This video data synthesizing process will be described later with reference to FIG. In the next step S53, the current time is set to Ctime. In step S54, the counter is initialized. That is, the counter k is set to 1 and the counter dk is set to 0. In the next step S55, it is determined whether or not the counter k is larger than the DATA counter. If larger (YES), the process proceeds to step S56, and if smaller (NO), the process proceeds to step S61.

In step S56, it is determined whether the counter dk is zero. If it is not 0 (NO), there is display data, and the process returns to step S53. When the counter dk is 0 (YES), since there is no display data, the video data composition processing unit 240 is reset in step S57. The reset processing of the video data composition processing unit 240 is as described with reference to FIG. In the next step S58, processing for returning to the display of only the broadcast video is performed. That is, the following processing is performed.
Disp_sx ← 0
Disp_sy ← 0
Disp_ex ← Panel_W-1
Disp_ey ← Panel_H-1
Disp_W ← Panel_W
Disp_H ← Panel_H
In step S59, the digital display data a is not displayed. Next, in step S60, video data composition processing is performed. This video data synthesizing process will be described later with reference to FIG.

If it is determined as NO in step S55, the process proceeds to step S61, and it is determined whether or not the display time has ended. That is, the process of Ctune-Stime> = Time [k] is performed. If the display time has ended, the data expansion processing task k is ended in step S62, the next data is checked in the next step S64, the counter k is incremented by k + 1, and the process returns to step S55. In step S61, if the display time has not expired, in step S63, the display data count is processed as dk = dk + 1, and the process proceeds to step S64. In this way, k tasks expanded in the data expansion memory 269 are processed.

FIG. 13 shows a detailed flowchart of the video data composition processing in steps S52 and S60 in FIG.
In step S71, the broadcast video memory 223 is cleared. In step S72, the data development memory 269 is cleared. In step S73, the broadcast video data is expanded. This step S73 will be described later with reference to FIG. In step S74, the counter is initialized. That is, k ← 1 is performed. Next, in step S75, it is determined whether the counter k is larger than the data counter. If it is smaller (NO), this flow ends. However, if it is larger (YES), a data k expansion processing task is performed in step S76. Step S76 will be described later with reference to FIG. In step S77, the next data is checked. That is, k = k + 1 is performed, and the process returns to step S75. As a result, all tasks are expanded.

  FIG. 14 shows a detailed flowchart of the broadcast video data expansion process performed in step S73 of FIG. First, in step S81, the tuner 221 is initialized and reception is started. In step S82, the decoder 222 is initialized and digitization is started. In step S83, the scaler 241 is initialized. As a result, (1) broadcast video data is set to be reduced or enlarged to (Disp_sx, Disp_sy) and (Disp_ex, Disp_ey) on the screen. (2) The task of the data development memory 269 is set to be synthesized and displayed.

  FIG. 15 shows a detailed flowchart of the data k expansion processing task in step S76 of FIG. First, in step S91, a process of reading a task storing the kth data in the data expansion processing units 261 to 26n is performed. In the next step S92, the read data is expanded to the positions (Disp_sx [k], Disp_sy [k]), (Disp_ex [k], Disp_ey [k]) on the data expansion memory 269. In the next step S93, it is determined whether the data is a moving image. If it is not a moving image (NO), this flow ends. In the case of a moving image (YES), the process proceeds to step S94, and it is determined whether the moving image has ended. If finished, this flow is finished. If not completed, in step S95, the next frame is developed at the positions (Disp_sx [k], Disp_sy [k]) and (Disp_ex [k], Disp_ey [k]) in the data display memory. Then, in step S96, switching to the next task is performed, and the process returns to step S94. Thereby, k tasks are displayed.
