BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a set-top box for downloading and applying an application program including an operating system, and more particularly, to a method for controlling rebooting when downloading an operating system of a set-top box. It is about.

Typically, set-top boxes download and apply applications, including operating systems, remotely to limit internal memory and to manage and control efficiency. The presence and presence of a download program from a server located remotely in a set-top box is determined by the DSM-CC (digital storage media-command) using the service provider's own protocol or standardized to ISO-IEC 13818-6, depending on the application. and control) use the download method. In addition, whether the target to be downloaded is an operating system or an application may be classified by the name of the file to be downloaded.

When the application program is downloaded, the set top box may normally execute the newly downloaded application without rebooting. However, in the case of the operating system that is the basis for operating the system, the newly downloaded operating system can be normally executed only after rebooting the set-top box.

Referring to FIG. 1, which shows a schematic configuration diagram of a set top box, the set top box 100 includes a CPU 102, a network interface unit 104, a graphic controller 106, a web browser 108, It is composed of a TV interface unit 110, a memory 112, a wireless interface unit 114. The CPU 102 controls the overall operation of the set top box 100. The network interface unit 104 communicates with the headend 120 through a wired network, a wireless network, a satellite, and transmits and receives data for service through an analog / digital broadcasting network, a VOD server, and an Internet network. The headend 120 is connected to an analog / digital broadcasting network, a VOD server, an internet network, and the like, so that various services from the analog / digital broadcasting network, a VOD server, and an internet network are provided through signaling with the set-top box 100. The graphic control unit 106 is used when displaying a menu or the like on the TV 122 or displaying the web browser 108 on the TV 122. The web browser 108 is a software module for providing a high speed internet service through the TV 122. The TV interface unit 110 is connected to the TV 122 and is connected between the TV 122 and the set-top box 100 so that a broadcast screen, an Internet screen, or a graphic screen is displayed on the TV 122 under the control of the CPU 102. Interface. The memory 112 stores not only the downloaded application program, the operating system, but also the data generated when the CPU 102 executes the program. The wireless interface unit 114 interfaces between the wireless keyboard 116 and the remote controller 118 and the CPU 102 to provide the CPU 102 with data input from the wireless keyboard 116 and the remote controller 118.

A conventional operating system and application downloading method will now be described with reference to FIG. In step 200, the CPU 102 searches whether the application program is downloaded through the network interface 104. In this case, when the application program is downloaded, the CPU 102 proceeds to step 202 to download the application program, and proceeds to step 204 to perform the downloaded application program.

If the application program is not downloaded in step 200, the CPU 102 proceeds to step 206 to search whether the operating system is downloaded. When the operating system is downloaded, the CPU 102 proceeds to step 208 and after downloading the operating system, proceeds to step 210. In step 210, the CPU 102 reboots the set-top box 100 to drive the set-top box 100 using the downloaded operating system.

As described above, when the operating system is downloaded, the set-top box is rebooted. When such a reboot is performed when the user is provided with the service through the set-top box, there is a difficulty in stopping the service.

Accordingly, in the related art, the downloading of the operating system is performed at a dawn time when the user is determined not to use the set-top box, but there may be a user who uses the set-top box even in this time zone. In this case, service interruption may occur due to the reboot by downloading the operating system.

As described above, in the conventional set-top box, there is a problem in that service interruption occurs due to the reboot due to the download of the operating system.

Accordingly, an object of the present invention is to provide a reboot control method by downloading an operating system of a set-top box by controlling the download of the operating system in accordance with the provision of a service, so that the service is not interrupted by the reboot due to the download of the operating system.

2 is a flowchart of a download method of a conventional operating system;

3 is a flowchart of a download method of an operating system according to a first preferred embodiment of the present invention;

4 is a flowchart of a download method of an operating system according to a second preferred embodiment of the present invention.

The present invention for achieving the above object comprises the step of searching whether the set-top box is in use when downloading the operating system, and if the set-top box is in use does not perform a reboot according to the download of the operating system It is done.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. While many specific details are set forth in the following description and in the accompanying drawings, to provide a more general understanding of the invention, these specific details are illustrated for the purpose of illustrating the invention and are not meant to limit the invention thereto. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

In the first preferred embodiment of the present invention, if the need for downloading of the operating system is detected in the set-top box, it is determined whether the service is provided through the set-top box, and when the service is being provided, the download of the operating system is suspended and the system is rebooted due to the downloading of the operating system. Prevent in advance.

The first embodiment will be described in detail with reference to FIG. 3 showing a flow chart according to the first preferred embodiment of the present invention and FIG. 1 showing a schematic configuration diagram of the set-top box.

In step 300 of FIG. 3, the CPU 102 detects whether the operating system needs to be downloaded. This provides the set top box 100 with the version of the operating system to be downloaded to the operating system to be downloaded when a predetermined time is established by the remote server, and the set top box 100 is based on the version of the operating system to be downloaded. By comparing the versions of the stored operating system, it is determined that the operating system should be downloaded if both versions are different. In this way, if the CPU 102 detects the necessity of downloading the operating system, the CPU 102 proceeds to step 304 to search whether the user is provided with a service such as a VOD through the set-top box 100. Here, whether the service is provided through the set top box 100 may be determined by whether the set top box 100 provides a video signal to the TV 122. If the user is provided with the service through the set-top box 100, the CPU 102 proceeds to step 306 to continue providing the service to the user while the download of the operating system is suspended. The suspended operating system can be downloaded at the time of download of the next operating system. If the user is not provided with the service through the set-top box 100 in step 304, the CPU 102 proceeds to step 308 to download the operating system and store the operating system in the memory 112. Thereafter, the CPU 102 proceeds to step 310 and performs a reboot to drive the set-top box 100 using the downloaded operating system.

In the second preferred embodiment of the present invention, if the necessity of downloading the operating system is detected in the set-top box, it is determined that the service is provided after the downloading of the operating system. If not, reboot the set-top box and run the downloaded operating system.

The second embodiment will be described in detail with reference to FIG. 4 showing a flow chart according to the second preferred embodiment of the present invention and FIG. 1 showing a schematic configuration diagram of the set top box.
