  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where the load of a server increases with the content of data broadcasting, the load of a server can be reduced by operation from the broadcast side.

  An embodiment of the present invention will be described.

  FIG. 1 is a diagram for explaining an embodiment of the present invention. In FIG. 1, 1 is a broadcasting station, 2 is a content server, and 3 is a television receiver that can be connected to the content server 2 (for example, a mobile phone capable of receiving 1 segment).

  The broadcasting station 1 is a broadcasting station that broadcasts data broadcasting contents of data broadcasting, and the data broadcasting contents are broadcasting contents in which the URL of the server 2 is described at the link destination. The broadcasting station 1 monitors the access status of the server 2 for each content.

  The server 2 stores the communication content linked to the URL described in the data broadcast content broadcast from the broadcast station 1, and the television receiver 3 that has been accessed to acquire the communication content is notified of the content. Communication content is transmitted.

  The television receiver 3 has a function of receiving a data broadcast and a communication function, and accesses the server 2 to acquire communication content related to the content broadcast from the broadcast station 1.

  The operation between the above three parties will be described.

  The broadcast station 1 broadcasts the data broadcast content in which the URL of the communication content of the server 2 is described at the link destination by data broadcasting (Step 1). The broadcast station 1 monitors the access status of the server 2 (Step 2).

  The television receiver 3 receives the data broadcast, and accesses to acquire the linked communication content based on the URL of the data broadcast content (Step 3).

  The server 2 transmits the communication content to the receiver 3 that has accessed (Step 4).

  When a certain load or more is detected on the server 2 (Step 5), the broadcasting station 1 broadcasts part or all of the communication content linked to the data broadcasting content by data broadcasting. (Step 6). In the receiver 3, the communication content is acquired not from the server 2 but from the data broadcast (Step 7).

  As a result, the number of accesses from the television receiver 3 to the server 2 is reduced, and the load on the server 2 is reduced.

  Specific Example 1 in the above-described embodiment will be described.

  In the first embodiment, when the load on the server 2 is detected, a case will be described in which the content of the link is included in the data broadcast content and the content is transmitted by data broadcast.

  2 is a block diagram of the broadcasting station 1 in the first embodiment, FIG. 3 is a block diagram of the server 2 in the first embodiment, and FIG. 4 is a block diagram of the receiver 3 in the first embodiment.

  As shown in FIG. 2, the broadcast station 1 includes a broadcast content storage unit 11, a data broadcast transmission unit 12, and a server load monitoring unit 13.

  The broadcast content storage unit 11 stores broadcast content broadcast by data broadcasting. The data broadcasting content stores two types of data broadcasting content for normal broadcasting and data broadcasting content broadcast when a load on the server 2 is detected.

  FIG. 5 shows data broadcast contents for normal broadcasting, and FIG. 6 shows data broadcast contents transmitted when server load is detected.

  In the data broadcasting content for normal broadcasting shown in FIG. 5, URLs of economic information and popular idol content are described, and by accessing the server 2 using these URLs, the economic information and popular idol content. Is acquired. On the other hand, in the data broadcast content transmitted at the time of detecting the server load shown in FIG. 6, the economic information remains unchanged, but the content is changed so as to acquire the popular idol content from the broadcast. That is, the data broadcast content shown in FIG. 6 is a data broadcast content that is transmitted when the load on the server 2 increases to acquire popular idle content. In the data broadcasting content shown in FIG. 6, the module number 0004 indicates that the popular idle content is stored, and the module number 0004 is not shown in the figure. Broadcast on broadcast.

  The data broadcast sending unit 12 broadcasts the data broadcast content stored in the broadcast content storage unit 11.

  The server load monitoring unit 13 monitors the access load status of the server 2. Specifically, when the number of accesses for a predetermined time notified from the server 2 reaches a predetermined number, the load on the server 2 is detected. The number of accesses is counted for each linked content.

  The server 2 includes a communication content storage unit 21, a communication content transmission unit 22, and a server load notification unit 23.

  The communication content storage unit 21 stores communication content to be provided to the television receiver that has been accessed based on the broadcast content of the data broadcast broadcast from the broadcast station 1.

  The communication content sending unit 22 transmits the communication content to the receiver 3 that has accessed the server 2 based on the broadcast content of the data broadcast broadcast from the broadcast station 1.

  The server load notification unit 23 notifies the broadcast station 1 of the access load status of the server 2. Specifically, based on the data broadcast content broadcast from the broadcast station 1, the number of accesses made to the server 2 in a predetermined time is counted, and this is notified to the broadcast station 1. The number of accesses is counted and notified for each content.

  The television receiver 3 includes a receiving unit 31 that receives data broadcasting, and a communication content acquisition unit 32 that accesses the server 2 and acquires communication content.

  Next, a specific operation will be described.

  First, the data broadcast sending unit 12 sends the data broadcast content for normal broadcast shown in FIG.

  The television receiver 3 receives the broadcast data broadcast content, and accesses the URL of the link destination described in the broadcast content according to the user's instruction.

  The server 2 transmits the content to the TV receiver 3 that has accessed, while counting the number of accesses for each content and notifies the broadcasting station 3 of the count. Here, assuming that the number of accesses for acquiring popular idol content has increased, the server load monitoring unit 13 of the broadcasting station 3 has reached the point when the number of accesses for acquiring popular idol content reaches a predetermined number within a certain time. The server 2 is detected to be loaded. Then, the result is notified to the data broadcast transmission unit 12. Then, the data broadcast transmission unit 12 transmits the data broadcast content for server load detection shown in FIG. 6 instead of the data broadcast content for normal broadcast.

  The television receiver 3 receives the data broadcast content when the server load is detected, and thereafter, the popular idle content is acquired by the module with the module number 0004 to be broadcast.

  Thereafter, there is no access to the server 2 for acquiring popular idle content, and the load on the server 2 is reduced.

  A second embodiment will be described.

  In the second embodiment, when the television receiver 3 has already transitioned to communication and it is detected that a load is applied to the server 2, a part of the communication content is put on the private area of the event message and transmitted. An example will be described.

  The difference from the first embodiment is that the broadcasting station 1 includes a communication content storage unit 14 and an event message transmission unit 15 as shown in FIG.

  The communication content storage unit 14 stores content similar to the communication content stored in the communication content storage unit 21 of the server 2.

  When the server load monitoring unit 13 detects that the server 2 is under load, the event message sending unit 15 reads the content causing the load on the server 2 from the communication content storage unit, and stores the private event message. Send it on the area.

  Further, the data broadcasting content as shown in FIG. 8 is stored in the communication content sending unit 22 of the server 2. This data broadcast content is content that is sent to the television receiver 3 that has accessed the server 2, monitors the reception of the event message, and if an event message is received, it is stored in the private area of the event message. A process is described in which the described content is acquired and displayed, and when no event message is received, the content is acquired by accessing the linked server 2.

  In the data broadcasting content as shown in FIG. 8, today's news content acquisition processing corresponds to this, and when no event message is received, that is, the number of accesses to today's news content is small, and the event message. Is not sent, the URL (http: //www.hogehoge/info.btb) described in the data broadcast content is accessed to obtain the content of today's news.

  On the other hand, if the number of accesses to today's news content is large and the load on the server 2 is increasing, an event message with a content ID of “NEWS” is transmitted. The receiver 2 acquires the content (content of today's news) described in the private area of the event message whose content ID is “NEWS”.

  According to such a configuration, even a receiver that has already transitioned to communication can perform an operation of reducing the load on the server 2 as in the first embodiment.

  In the above-described embodiment, the example in which the content causing the load on the server 2 is described and transmitted in the private area of the event message has been described. However, a module may be used instead of the event message.

  An example of data broadcasting content when using a module is shown in FIG.

  In the data broadcasting content as shown in FIG. 9, the acquisition processing of today's news content corresponds to this, and when the module is not received, that is, the number of accesses of today's news content is small, and the module sends out. If not, the URL (http: //www.hogehoge/info.btb) described in the data broadcasting content is accessed to obtain the content of today's news.

  On the other hand, when the number of accesses to today's news content is large and the load on the server 2 is increasing, the module with the module number “40/1000 /” is updated. The receiver 2 acquires content (content of today's news) from the binary table “40/1000 / info.btb”.
