When the recording start SMS is received, the control unit 102 records the viewing history in response to the viewing history recording start SMS having the first TID and stores it in the memory 104 (step S202). Store statistics for every event that a customer changes channel during the service and watches for at least 10 seconds.

In step S203, the control unit 102 determines whether the viewing history record has exceeded 48 hours.

As a result of the determination in step S203, when the viewing history record does not exceed 48 hours, the processing routine returns to step S202. On the contrary, if the viewing history record exceeds 48 hours, the controller 102 deletes the oldest record stored in the memory 104 (step S204).

In step S205, the control unit 102 determines whether the viewing history recording end SMS having the second TID as shown in [Table 2] has been received from the digital broadcasting server 100.

As a result of the determination in step S205, when the viewing history recording end SMS having the second TID is received, the control unit 102 stops recording the viewing history and returns previously recorded viewing history information from the memory 104. It deletes (step S206).

In step S207, the control unit 102 determines whether the viewing history transmission SMS having the third TID as shown in [Table 3] has been received from the digital broadcasting server 100.

The broadcaster server 100 transmits the following SMS at a specific time, for example, at 1 am.

TABLE 3

division Contents Remarks TID OOOOO message Type 1 (see below) 2.5G or higher transmission Type 2 (see below) 2G or higher transmission

There are two types of message bodies: return URL and network information.

<Type 1>

<Type 2>

When receiving the three types of SMS, the DMB terminal 101 should observe the following. First, when receiving an SMS, the related content should not be displayed on the DMB terminal 101, and an SMS incoming alarm should not appear. Second, even if a voice call is received or an SMS is received in a data call state, the existing call should not be affected. In particular, when receiving the viewing history transmission SMS having the third TID, when Network Info = 2.5G Only is included, that is, when receiving the type 1 SMS, DMB terminal 101 is 2.5 Only when the G network is tuned, the reverse data call connection should be attempted using the return URL. In the state of tuning to the 2G network, only the recognition message for this SMS reception is sent to the network, and the reverse data call connection is not attempted. . As another example, when Network Info = 2G Included is included, that is, when a type 2 SMS is received, the DMB terminal 101 is tuned to the 2.5G network in the 2.5G network and to the 2G network. In 2G network, each user should try data call connection using return URL. Other SMS operation procedures follow the existing SMS operation procedures of IS-95.

When the DMB terminal 101 receives the SMS of the specific TID, the viewing history information format is used to perform the function of transmitting the stored viewing history information to the designated broadcasting server. The DMB terminal should be able to store two days of statistical data in a file. However, save files are stored on a daily basis. The file name is "Today's Date_Smart Card ID". The file transferred from 02:00 on January 1, 04 to 02 on January 2, 04 will be named “20040102_Smart Card ID”. One-day statistical data means data from 02:00 yesterday to 02:00 today. History information viewed over 02:00 is divided into 2 days based on 02:00 and separately managed. In this case, even if you watch 10 seconds or less, it is stored.

As a result of the determination in step S207, when the viewing history transmission SMS having the third TID is received, the uploading unit 106 stores the viewing history stored and recorded in the memory 104 under the control of the control unit 102, and the digital broadcasting company. Upload to server 100 (step S208). If there is no history information watched for the two days, the upload unit 106 fills in all binary numbers with '1' for one event and uploads it to the digital broadcasting server 100.

When receiving the specific TID SMS, that is, the third TID shown in [Table 3], the DMB terminal 101 uploads the viewing history information stored from 02:00 yesterday to 02:00 today. The viewing history transmission method uses the http protocol and the server address will be announced later. If there is no history information watched from 02:00 yesterday to 02:00 today, the DMB terminal 101 fills the binary with '1' for one event and uploads it to the server. For example, since one inventory is 14 bytes, the 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFF value is uploaded to the broadcast server 100. Delete the transmitted file after transferring the data. Also, even if the saved file cannot be transferred, the data of two days ago is automatically deleted. [Table 4] below shows the record contents and format stored for each event.
