Next, the data transfer rate determination processing in the video transmission / reception system of the present embodiment will be specifically described with reference to FIGS.

  FIG. 2 is a flowchart showing data transfer rate determination processing according to this embodiment.

<S500>
When the user operates the portable terminal 10 to execute the data transfer rate determination process in order to determine the optimal location of the STB 30 (S500), the server processing unit 102 of the CPU 100 exchanges data with the receiving device 20 Is executed, a process for setting the mobile terminal 10 to the web server state is executed. As a result, the receiving device 20 can perform data transmission / reception with the mobile terminal 10 by executing a process of accessing the web server of the mobile terminal 10 with a web browser. Then, the CPU 100 displays an address for accessing the web server of the mobile terminal 10 on the display unit 120. FIG. 3 is an example of a screen display on the display unit 120 at this time.

As a result, data can be transmitted and received by wireless connection between the receiving device 20 and the mobile terminal 10.

<S510>
Next, the data transmission / reception unit 110 of the mobile terminal 10 transfers a transfer rate determination data file for determining the data transfer rate to the data transmission / reception unit 210 of the reception device 20. The data transmitting / receiving unit 110 outputs to the transfer rate determining unit 101 the reception status in the receiving device 20 of the transfer rate determining data file transmitted here. The transfer rate determination unit 101 acquires the data transfer rate between the mobile terminal 10 and the reception device 20 based on the reception amount in the unit time of the transfer rate determination data file in the reception device 20 (S510). The acquisition of the data transfer rate mentioned here is an example, and another method may be adopted as a method for determining the data transfer rate.

<S520>
Next, the transfer rate determination unit 101 determines whether or not the acquired data transfer rate is equal to or higher than a predetermined threshold (S520). The threshold value here is determined in advance based on a transfer speed that does not cause a problem due to lack of video data when the receiving device 20 reproduces the video based on the video data received from the STB 30.

<S530, S600>
If the acquired data transfer rate is equal to or greater than the threshold (Y in S520), the transfer rate determination unit 101 causes the display unit 120 to display information indicating that the data transfer rate has been secured (S530). Then, the data transfer rate determination process ends (S600). The control of the display unit 120 may be executed by the CPU 100. FIG. 4 is an example of a screen display on the display unit 120 of the portable terminal 10 in the process of S530.

<S531, S600>
On the other hand, when the acquired data transfer rate is less than the threshold (N in S520), the transfer rate determination unit 101 causes the display unit 120 to display information indicating that the data transfer rate cannot be ensured. Then, the data transfer rate determination process ends (S600).

  As a result of the above data transfer rate determination process, the display unit 120 displays whether the data transfer rate is secured or not, and the user determines the position where the STB 30 is to be placed based on this display. It will be.

The transfer rate determination unit 101 compares the measured data transfer rate with a plurality of predetermined thresholds to determine whether the data transfer rate between the mobile terminal 10 and the receiving device 20 is equal to or higher than a predetermined rate. Can be determined step by step.

<(2) Specific Example of Data Transfer Rate Determination Process>
Next, the data transfer rate determination processing in the video transmission / reception system of this embodiment will be specifically described with reference to FIGS. Compared with the data transfer rate determination process (see FIG. 2) of the first embodiment, the process of S520, S530, and S531 is different from the process of S521, S522, and S540 to S542 in the data transfer rate determination process of the present embodiment. It differs in that it has been changed.

<S521>
After the processing of S510, the transfer rate determination unit 101 determines whether the acquired data transfer rate is equal to or higher than a predetermined threshold 1 (S521). The threshold value 1 here is not caused by a shortage of video data when a video is reproduced based on high-quality video data received by the receiving device 20 from the STB 30 and having a relatively large amount of data per unit time. It is determined in advance based on such a transfer rate.

<S522>
After the process of S521, the transfer rate determination unit 101 determines whether the acquired data transfer rate is equal to or greater than a predetermined threshold 2 (S522). The threshold value 2 here does not cause a problem due to lack of video data when the video is reproduced based on low-quality video data received by the receiving device 20 from the STB 30 with a relatively small amount of data per unit time. It is determined in advance based on such a transfer rate.

<S540, S600>
When the acquired data transfer rate is a value equal to or greater than the threshold value 1 (Y in S521), the transfer rate determination unit 101 displays information indicating that a data transfer rate at which a high-quality moving image can be reproduced is ensured. (S540). Then, the data transfer rate determination process ends (S600).

<S541, S600>
When the acquired data transfer rate is a value equal to or greater than the threshold value 2 (Y in S522), the transfer rate determination unit 101 displays information indicating that a data transfer rate at which a low-quality moving image can be reproduced is secured. (S541). Then, the data transfer rate determination process ends (S600). FIG. 6 is an example of a screen display on the display unit 120 of the portable terminal 10 in the process of S541.

<S542, S600>
On the other hand, when the acquired data transfer rate is a value less than the threshold 2 (N in S522), the transfer rate determination unit 101 causes the display unit 120 to display information indicating that the data transfer rate cannot be ensured. Then, the data transfer rate determination process ends (S600).

<3. Embodiment 3>

It should be noted that various generally known methods can be adopted as the method for obtaining the decoding rate.

<S523>
Next, the decoding rate determination unit 250 determines whether or not the acquired decoding rate is equal to or greater than a predetermined threshold (S523). The threshold here is determined in advance based on a decoding rate that does not cause a problem due to lack of video data when the video is played back based on the video data received by the receiving device 20 from the STB 30.

<S550, S601>
If the acquired decoding rate is equal to or greater than the threshold value (Y in S523), the CPU 100 causes the display unit 120 to display information indicating that the video can be displayed smoothly if the STB 30 is placed at the determination time. (S550). Then, the decoding rate determination process ends (S601).

The threshold value 2 here does not cause a problem due to lack of video data when the video is reproduced based on low-quality video data received by the receiving device 20 from the STB 30 with a relatively small amount of data per unit time. It is determined in advance based on such a decoding rate.

<S560, S601>
When the acquired data transfer rate is a value equal to or greater than the threshold 1 (Y in S524), the decoding rate determination unit 250 displays information indicating that a high-quality moving image can be displayed smoothly on the display unit 120 (S560). . Then, the data transfer rate determination process ends (S601).

<S561, S601>
