In particular, the present invention relates to dynamic class loading that enables unlimited (quantity) application execution in a set-top box (STB) through real-time management of applications in the service platform. (Dynamic Class Loading: DCL) Technology-based interactive service platform and its service method. In addition, the Launcher pre-loaded in the STB manages the application based on the DCL, and the interactive service platform and the service method based on the DCL technology enable the free interaction and control between the applications in the service platform. It is about.

TV broadcasting provides programs to unspecified many people in one direction due to the nature of the mass media, and viewers can select and watch the desired programs from the numerous programs through channel search. This is being planned and provided.

In order to circumvent this broadcasting operation, a set-top box (STB) receiving broadcast information in recent years, a digital video storage device (DVR) storing and reproducing the information on a hard disk, and an IP that transmits video information to a remote terminal through IP communication are provided. By constructing streamer devices, methods for recording broadcast information and watching at a desired time have been proposed.

In addition, Internet Protocol Television (IPTV) is a digital convergence type in which broadcasting and communication are combined, and in addition to receiving broadcast signals transmitted from a program provider (PP) or terrestrial, cable, and satellite. It is a television receiver (TV) connected to an IP set-top box (STB) and provides Internet Contents On Demand (ICOD) services such as TV Internet contents and video contents (T-VOD) through an IP network. These IPTV services are called IPTV in the US, ADSL TV in Europe, and broadband broadcasting in Japan.

The IPTV service is an IP STB service through a broadband high-speed internet network. A TV connected to the terminal receives Internet multimedia content including audio, video, and packet data, and uses a TV service interactively by using a bidirectional communication channel as a return path concept.

As such, the STB is an interface device between the TV and the network. The STB is a platform for transmitting channels and two-way services transmitted through a network through an IP cable, satellite, and terrestrial wave. The STB maintains three states: boot, standby, and operational. The boot state is a state in which the STB loads components necessary to show a service and initializes resources in the STB. The standby state is a state in which the user does not use the service, and the operating state is a state in which the user uses the service.

However, STB has evolved to enable bi-directional service by securing a return path even for one-way reception. However, since STB memory cannot be expanded indefinitely due to the static allocation structure, various applications reside in STB memory due to the limitation of physical memory, thereby providing more diversified application services. It is difficult and can only service a limited application to the user.
