First, the 3G mobile terminal 1 is connected to the Internet via the Internet connection service server 2 to access the program information site (step S208). By sending the program information to the 3G mobile terminal 1 via the Internet connection service server 2 (step S209), information about the program that can receive the distribution service is obtained. By referring to this information, the user selects the channel of the program he / she wants to watch. Then, a channel is converted into a telephone number by a phone to function (a function of making a one-push call directly from the Internet browsing screen). Make a multi-call call (step S21)
0). The call by this multi-call is input to the PBX 5 (step S211) and is distributed to an idle line.

Then, the incoming call information output corresponding to one call of the multi-call is input to the content distribution server 11. Further, extension transfer is performed to the 3G fixed terminal 6 in response to another call of the multi-call (step S21).
2). As a result, the call is received at the 3G fixed terminal 6. Content distribution server 11 to 3
A moving image output signal is sent to the G fixed terminal 6 (step S213), and a television signal is sent to the 3G portable terminal 1 via the 3G fixed terminal 6 as in the case of communication by a TV phone (step S214). ).

In this case, videophone communication according to the 3G-324M standard is performed between the 3G fixed terminal 6 and the 3G mobile terminal 1. At this time, since the encoded television program is input to the 3G fixed terminal 6, the encoded television program is distributed to the 3G mobile terminal 1. Next, the CM information distribution partial processing and service end processing will be described with reference to FIG. (CM Information Distribution Partial Processing) In the figure, the CM information distribution partial processing is performed as follows. When a call is made from the 3G mobile terminal 1 via the program information site, 3G
The mobile terminal 1 and the PBX 5 are connected. The PBX 5 informs the content distribution server 1 of the fact that a call has been made, its calling number, etc.
Notify 1.

Then, the content distribution server 11 inquires of the user information DB server 12 about the calling number (step S301). In response to this inquiry, the user attribute information is sent from the user information DB server 12 to the content distribution server 11 (step S
302). Then, a CM data request is sent from the content distribution server 11 to the CMDB server 13 based on this user attribute information (step S30).
3). In response to this request, the CMDB server 13
CM information is downloaded from the content distribution server 11 to the content distribution server 11 (step S304). This download may be performed in real time when the CM information is distributed, or the CM information may be transferred in fixed amounts. Which of these methods is adopted is determined by the processing capacity of the server, the communication line quality, and the like.

Next, the content distribution server 11 detects the CM information portion, that is, the CM frame, of the television signal (step S30).
5). When the CM information part is detected, the content distribution server 11 sends a television signal by an analog signal to the 3G fixed terminal 6 (step S306). As a result, the distribution switching from the television program to the CM information is performed only during the CM frame. The 3G fixed terminal 6 sends the television signal sent from the content distribution server 11 to the 3G mobile terminal 1 by videophone communication (step S307). (Detection of CM Frame) Here, a method of detecting a CM frame in the received and encoded television signal will be described.

In general, CM information is often stereo audio, whereas television programs are often monaural audio. Therefore, the CM start timing and the CM end timing, that is, the CM frame can be detected by detecting the change in the audio signal. And
If the CM information has a time length that is an integral multiple of a fixed time length (for example, 15 seconds), when the audio signal changes from a stereo signal to a monaural signal at a timing with the fixed time length as one unit, the CM end timing Can be detected. Therefore, the CM frame can be detected.

If an identification code (hereinafter referred to as a CM code) indicating how long the CM lasts is inserted in the CM information in advance, the CM start timing can be detected by the insertion of the CM code. , The timing at which the time designated by the CM code elapses, that is, the CM end timing can be detected. Therefore, the CM frame can be detected.

Furthermore, both voice signal conversion and CM code may be used. The CM start timing can be detected by the insertion of the CM code, and the CM end timing can be detected by detecting the change from the stereo sound to the monaural signal at the timing whose fixed time length is one unit. It should be noted that the CM information is always kept flowing (drifting state), and the CM is displayed only during the time corresponding to the CM frame.
Distribution control may be performed so as to switch to information. In this case, since simple control of switching the input source is sufficient, the system configuration can be simplified. In this case, there is no problem if such a contract is made with the CM sponsor side.

Further, if the time length of the CM information is set to be slightly shorter than the time length of the CM frame, there is a time margin, and thus the generated time can be used to switch the signal. it can. By doing so, it is possible to smoothly switch signals between the program part and the CM information part. (Service end processing) When the user disconnects the call, the service ends. Which C
A feedback process is required to inform the CM sponsor how much (how many times) the M information has been sent.

This service end processing is performed as follows. First, when the call is disconnected by the 3G mobile terminal 1, a disconnection signal is sent to the PBX 5 (step S30).
8). Then, the PBX 5 sends a disconnection signal to the 3G fixed terminal 6 to notify that the call has been disconnected (step S309). At the same time, the PBX 5 also notifies the content distribution server 11 of the disconnection information (step S31).
0). As a result, the 3G fixed terminal 6 enters a state of waiting for the next call (a state in which the call can be accepted).

Upon receiving the disconnection information, the content distribution server 11 sends the log information about the distributed CM information to the user information DB server 12 (step S311). This log information is registered in the user information database 120 by the user information DB server 12. When the registration in the user information database 120 is completed, the user information DB server 12 sends a service end signal to the content distribution server 11 (step S312). As a result, the content distribution server 11 is in a state of waiting for the next call.

Note that the billing process is performed as the service ends. However, it is desirable that only the communication fee is charged to the user of the 3G mobile terminal 1, and the viewing fee of the television program itself is not charged. In this case, C
The sponsor of the M information will pay the costs associated with the distribution of the television program itself. The operation of the 3G mobile terminal 1 in FIG. 1 will be described with reference to FIGS. 5 and 6.

FIG. 5 is a flowchart showing the pre-registration process of user attributes in the 3G mobile terminal. In the figure, first, by operating the 3G mobile terminal,

By accessing this site, user attributes can be registered in the user information database 120 from the 3G mobile terminal (step S40).
2). By registering this user attribute, the user is permitted to use the service of this system, that is, the television program distribution service (step S403).

On the other hand, FIG. 6 is a flowchart showing a navigation process for content distribution in the 3G mobile terminal. In the figure, first, the program information site is accessed by operating the 3G mobile terminal (step S501). By accessing this site, the program information can be browsed on the 3G mobile terminal (step S502). This acquired program information is
Since it is displayed on the screen of the 3G mobile terminal, the user can select the channel he / she desires to view by checking the displayed content (step S503).

When the channel you want to watch is decided, ph
The one-to function is used to make a call and connect to the line (step S504). When this call is made, the PBX allocates the call to an empty line as described above,
The television program is distributed from the content distribution server to the 3G mobile terminal (step S505). The operation of the content distribution server 11 in FIG. 1 will be described with reference to FIG. This figure is a flowchart showing the control procedure of the content distribution server. In the figure, when a user makes a call, the user attribute information corresponding to the calling number is acquired (step S601). The CM information corresponding to the acquired user attribute is acquired from the DB (step S602).

Next, C included in the television program
The M frame is detected (step S603). When the CM frame included in the television program is detected, C is displayed in that part.
CM information is inserted by overwriting M (step S
604). The above CM frame detection and CM information insertion are

5 → S602 ...). When the call is disconnected, the CM distribution log information is stored in the user information database (steps S605 → S606). (First Modification) As a modification of this system, a system configuration that does not use PBX can be considered. In this case,
3G fixed terminal 6 and ISDN network 4
The system configuration is directly connected to. PB like this
If X is not used, the service specifically transits as follows. 1. The user uses the 3G mobile terminal 1 to access the program information site and performs user registration. This user registration is performed only at the first viewing. 2. Also, the user accesses the program information site using the 3G mobile terminal 1 and selects the program to be viewed. in this case,
Inquire from the program information site whether there is a free line to watch the selected program. 3. The free line can be determined by whether or not an image output signal is input to the content distribution server 11. Whether or not an image output signal is input to the content distribution server 11 can be determined from the 3G fixed terminal 6. 4. If there is a free line, we will guide you from the program information site. Guides available 3G fixed terminals with AVTO function. Regarding the 3G fixed terminal which has been once guided, it is assumed that the 3G fixed terminal is not guided to other users for a fixed time (for example, one minute). 5. A user uses a 3G mobile terminal to make a videophone communication call to an available 3G fixed terminal. 6. If an incoming call arrives within a certain time (for example, 1 minute) after the guide of the program information site is received, it is determined that the incoming call is from the user who has just been guided, and the TV in which the CM content matching the user attribute is inserted. Deliver John's program. (Second Modification) As another modification, 3G is further added.
A system configuration that does not use fixed terminals is conceivable. In this case, an ISDN interface board is provided in the content distribution server. When the 3G fixed terminal is not used, the television program is directly sent from the content distribution server 11 to the ISDN network 4 as shown in FIG. By configuring the system in this way, it is not necessary to provide a 3G fixed terminal. (User Attribute) Here, the content of the user attribute will be described.
