1 is a configuration diagram of a heterogeneous application execution system according to an embodiment of the present invention. Referring to FIG. 1, a heterogeneous application execution system 1 may include a broadcast transmission system 110 and a device 120. The broadcast transmission system 110 and the device 120 shown in FIG. 1 illustratively show the components that can be controlled by the heterogeneous application execution system 1. In FIG.

Each component of the heterogeneous application execution system 1 of FIG. 1 is generally connected via a network. For example, as shown in FIG. 1, the device 120 may be coupled to the broadcast transmission system 110 via a network.

A network refers to a connection structure in which information can be exchanged between nodes such as terminals and servers. An example of such a network is Wi-Fi, Bluetooth, Internet, LAN Network, wireless LAN, WAN, PAN, 3G, 4G, LTE, and the like.

The broadcast transmission system 110 can generate a TS stream including a first application and a second application of different standards through one channel and transmit the generated TS to the device 120. [ At this time, the first application may be an application of the ACAP (Adapted Common Application Platform) standard, and the second application may be an application of the Open IPTV Forum (OIPF) standard.

The device 120 may receive a stream including a first application and a second application of different specifications from the broadcast transmission system 110 via one channel. At this time, the device 120 may be an ACAP standard-based device 120.

The device 120 may analyze the AIT (Application Information Table) information of the received first application and the second application, and may read the predetermined field value in the AIT information. The AIT information may include, for example, a specification of the application and predetermined field values. For example, the device 120 may analyze a first application of the ACAP standard as an application of the same specification as the device 120, analyze the second application of the OIPF specification as an application of a heterogeneous specification, .

The first application of the ACAP standard is generated on the basis of the Java language and can be executed on a broadcasting platform supporting terrestrial TV broadcasting. The second application of the OIPF standard is generated on the basis of an HTML language, Platform. Therefore, the device 120 of the ACAP standard can execute the first application of the ACAP standard, but can not execute the second application of the OIPF standard. Therefore, the second application of the OIPF standard must be recognized and then virtualized and executed.

The device 120 may determine whether a virtualization manager is present in the device 120 and select one of the first application and the second application to execute based on the predetermined field value. At this time, the predetermined field value may be 0xFF. For example, if the virtualization manager is present in the device 120 and the predefined field value in the AIT information of the second application is 0xFF, then the device 120 may send a second application, which is an application of a heterogeneous specification, And can be executed by virtualization. If the virtualization manager does not exist in the device 120 or if the preset field value in the AIT information of the second application is not 0xFF, 1 applications.

2 is a configuration diagram of a device according to an embodiment of the present invention. Referring to FIG. 2, the device 120 may include a receiving unit 210, an analyzing unit 220, a reading unit 230, a determining unit 240, and an executing unit 250.

The receiving unit 210 may receive a stream including a first application and a second application of different specifications from the broadcast transmission system 110 through one channel. The stream may comprise, for example, a first application of the Advanced Coomon Application Platform (ACAP) specification and a second application of the Open IPTV Forum (OIPF) specification. At this time, the stream may include AIT (Application Information Table) information corresponding to each application.

The analyzer 220 may analyze the AIT (Application Information Table) information of the received first application and the second application. The AIT information may include, for example, application specifications and predetermined field values. For example, the analyzer 220 can grasp the specifications of the first application and the second application through the analysis of the AIT information of the first application and the second application. The analyzer 220 can determine from the received stream that a first application of the ACAP (Advanced Common Application Platform) standard and a second application of the OIPF (Open IPTV Forum) standard are included, Can recognize that the first application is an application having the same standard as the device 120 based on the ACAP standard, recognizes the second application of the OIPF standard as a virtualization target application, and can recognize that the second application should be virtualized and executed have. For example, the analysis unit 220 may analyze the AIT information of the first application and the second application to analyze a predetermined field value in the AIT.

The reading unit 230 can read the predetermined field value in the AIT information. For example, the read unit 230 may read a predetermined field value for a second application whose application specification is 'OIPF'. At this time, the predetermined field value may be, for example, 0xFF.

The determination unit 240 may determine whether a virtualization manager exists in the device 120. [ For example, when the virtualization manager exists in the device 120, the determination unit 240 may determine that the device 120 is a device capable of supporting the virtualization service. For example, if the virtualization manager does not exist in the device 120, the determination unit 240 may determine that the device 120 is a device that can not support the virtualization service.

The execution unit 250 can select and execute one of the first application and the second application. For example, the execution unit 250 can select one of the first application and the second application and execute the virtual application based on whether the virtualization manager exists in the device 110 or not. If the determination unit 240 determines that a virtualization manager exists in the device 120, the execution unit 250 may virtualize the second application and execute the virtualization manager. Alternatively, if the determination unit 240 determines that the virtualization manager does not exist in the device 120, the execution unit 250 may execute the first application.

For example, the execution unit 250 may execute one of the first application and the second application based on the predetermined field value. The execution unit 250 may virtualize the second application and execute the second application if the field value preset to the second application as the virtualization target application is 0xFF. At this time, if the field value preset in the second application as the virtualization target application is not 0xFF, the execution unit 250 can execute the first application having the same standard as the standard supported by the device 120. [

When executed by a computing device, the device 120 receives a stream comprising a first application and a second application of different specifications over a channel from the broadcast transmission system 110, Analyzes application information table (AIT) information of the application and the second application, reads predetermined field values in the AIT, and selects one of the first application and the second application to be executed based on the predetermined field value A computer program containing a sequence of instructions can be provided.
