The above-mentioned publications disclose various techniques used for digital broadcasting, but all of the techniques disclosed in the above-mentioned publications are subscriber responses directed from a subscriber to a broadcasting station via a cable television station. The technical field is completely different from the present invention relating to the processing of data in a cable television station.

[0010] Further, conventionally, there is a telegong as a method of totaling reply results from subscribers related to broadcast programs. Telegong is a service that aggregates and notifies the number of telephone calls from viewers in conjunction with broadcasting. It is a method of associating telephone numbers with the answer options for questions and totaling the number of calls. The aggregated data is updated about every 5 seconds, and you can check the aggregated results on your PC at the broadcasting station. Since the totaled result is notified in real time, this result can be reflected in the program.

This telegon technology is also completely different in technical field from the present invention relating to processing in the cable television station of subscriber response data sent from the subscriber to the broadcasting station via the cable television station.

[0012]

As described above, in the interactive digital broadcast program using the cable television, since various services are provided, the subscriber response data has different data attributes for each program. There are the following drawbacks in providing interactive digital broadcast programs using cable television.

The first drawback is that in a program that instantly generates a large number of calls, when response data is transmitted between stations (between cable television stations and broadcasting stations) for each call, a large amount of data flows through the inter-station network. , Concentrate on one broadcasting station all at once.

The second drawback is that the throughput of the server of the broadcasting station exceeds the throughput of the server, depending on the attribute of the data.

An object of the present invention is to eliminate the above-mentioned first and second drawbacks and to respond to upstream subscriber response data of a two-way digital broadcasting service in a cable television in a cable television station according to the attribute of the data. It is intended to reduce the amount of response data flowing through the network between stations (between the cable television station and the broadcasting station) by processing and to reduce the load of the server installed in the broadcasting station.

[0016]

SUMMARY OF THE INVENTION According to the present invention, an attribute of upstream subscriber response data is analyzed in a broadcasting station prior to broadcasting, and a cable television station is equipped with a data processing device to perform some of the functions of the broadcasting station. Subscriber response by having a certain data processing function, notify the attribute of response data from the broadcasting station to the cable TV station in advance, and process (eg, aggregate), sort, classify, and organize the subscriber response data based on this attribute. It aggregates data.

That is, according to the present invention, the cable television station is provided with the data processing device, and not only the data is simply aggregated, but also the subscriber response data is processed, selected, classified and organized according to the attribute of the subscriber response data. By aggregating, the processing according to the attribute of the subscriber response data of the broadcast program is performed.

As described above, in the present invention, by introducing the data processing device in the cable television station, the subscriber response data is aggregated, and the amount of traffic flowing between the stations (between the cable television station and the broadcasting station) is significantly reduced. The congestion of the inter-station network can be avoided and the load on the server of the broadcasting station can be reduced. In addition, it enables local cable TV operators to add their own interactive data to interactive digital broadcasting services and collect data on local viewers.
