The present invention relates to a system and method for transmitting application data in digital broadcasting, and more particularly, to providing a data service that is updated in real time when a user uses an application of digital broadcasting through a set-top box. The present invention relates to an application data transmission system and method thereof in digital broadcasting, which are all possible in a unicasting environment.

In the past, when broadcasting was analog and the Internet was digital, the combination between broadcasting and the Internet was impossible. However, in the present time when broadcasting is digitized, new attempts are being made to combine broadcasting and the Internet by data broadcasting. In the era of analog broadcasting, data transmission was only limited text transmission, but in the digital broadcasting era, various services such as e-mail, EPG, TV banking, telephone service, internet search, etc. are provided through TV receivers as well as information services such as weather and news. ought. As such, data broadcasting is evolving while providing various new services according to the development of related applications.

1 is a view showing the configuration of a data broadcasting system according to the prior art. As shown, the data broadcasting system includes a broadcasting station 100 including a data server 101, a corusel server 102, an application server 103, a digital broadcasting server 104, and a multiplexer 105, and a set-top box ( SetTop Box) 110.

The Corusel server 102 takes over the data transmitted from the original data server 120 to the data server 101 and combines with the application to form an application format including the data. The application server 103 holds an application comprising data formed by the COURcell server 102 and sends the application to the multiplexer 105 along with the audio / video stream generated by the digital broadcast server 104. In this case, the application refers to an application program executed on the basis of a JVM (java virtual machine) in a digital broadcasting receiver. The application is transmitted from the broadcasting station, tuned at the request of the user, and then loaded into the digital broadcast receiver.

The core of the existing digital broadcasting service is the application running in the TV environment. However, as time goes by, platform operators' requirements are increasingly diverse and new applications are being developed and delivered to customers, which is significant in systems that must broadcast all of their growing applications in the current way, broadcasting / multicasting. In this situation, it is difficult to provide a smooth service by generating an overload within a limited network bandwidth because only a customer needs to use a specific application while transmitting all the applications that are not actually used by applying the aforementioned Courcell server method. This will happen. In order to solve the above problems, the present applicant has disclosed the invention of "Application Unicasting Transmission System and Method in Digital Broadcasting" on July 21, 2006 to Patent Application No. 10-2006-0068610. Filed.

By the way, the data used by the application in the digital broadcast was also delivered together with the application and updated data as a broadcast signal. On the contrary, even after improving the application to serve as a unicasting method as mentioned above, data which is updated frequently has been developed to directly access and import the data supply server. In this case, in case of broadcasting application, if the transmission method is changed to unicasting, the data is not updated.If the data is imported into unicasting, the external data server must be installed as a service zone accessible from all set-top boxes. There is a problem.
