As described above, in the conventional digital broadcasting, not only the digital broadcast service provider provides simultaneous broadcast information to the viewer, but also the viewer sends the digital broadcast service to the digital broadcast service provider side, for example, in the public domain. Line 300
It is also possible to transmit information on the viewer side using a wired medium such as the above, and it is possible to realize bidirectionality between the provider of the digital broadcasting service and the viewer for information transfer.

In such digital broadcasting, data broadcasting in which data is multiplexed and transmitted to video and audio main program information is possible.
The main type is independent data broadcasting that does not require synchronization with audio main program information, and is data broadcasting linked to the video / audio main program information, that is, data broadcasting synchronized with the video / audio main program information. At present, there is no link-type data broadcasting that performs this.

[0008]

The conventional digital broadcasting service is as described above, and in a situation where linked data broadcasting is to be implemented, a broadcasting company including a digital broadcasting service provider is provided. Therefore, it is important to ensure that data broadcasting content tests and interactive service demonstration tests are performed before actual broadcasting. In particular, verification of whether data broadcasting linked to the main program, for example, a program content such as a CM and data content of merchandise information, which is the content of the CM, will be linked to provide a broadcasting service must be paid for in the advertising fee. This is important for broadcasters who rely on much of their revenue.

The need for the above-described verification of the digital broadcasting service for performing data broadcasting linked to the main program is apparent from the following. In other words, in response to the digital broadcasting service that is to be implemented in the near future, each manufacturer has developed a digital broadcasting tuner device corresponding to the digital broadcasting service and a receiver such as a television receiver incorporating the digital broadcasting tuner device. Is currently in the process of, or has almost completed its development. However, for data broadcasting linked to the main program, since the H / W and S / W configurations of the data processing system are different for each manufacturer, for example, the data amount of the main program and the data broadcasting is reduced. If the size is large, the receiving devices of all manufacturers may not be able to correctly interpret the program content such as the CM and the data content of the product information that is the content of the CM due to differences in the data processing method and the memory capacity of each manufacturer. At present, it is not always possible to guarantee the linked broadcasting service to the viewer. For this reason, an environment is desired in which a creator of a program content such as a CM can confirm in advance a preview in a format to be actually broadcast in a state of simulating an actual broadcast. There is a problem that a simple environment is not currently provided.

It is an object of the present invention to provide a data broadcasting test system which realizes an environment in which a preview in an actually broadcast format can be confirmed in advance for an interlocked data broadcasting.
