Hereinafter, with reference to the accompanying drawings, it will be described in detail the present invention.

1 is a block diagram schematically illustrating a set top box according to an embodiment of the present invention.

Referring to FIG. 1, the set top box 100 according to the present invention includes a tuner 105, a demultiplexer 110, an audio processor 115, an image processor 120, an input unit 125, and transmission / reception of a signal. The unit 130, a memory 135, and a controller 140 are included.

In detail, the tuner 105 sets an arbitrary channel among a plurality of channels as an input channel, and receives a broadcast signal corresponding to the input channel from an external antenna 200 to provide it to the demultiplexer 110.

The demultiplexer 110 divides the broadcast signal received from the tuner 105 into an image signal and an audio signal and provides the same to the audio processor 115 and the image processor 120.

The audio processor 115 decodes and outputs an audio signal received from the demultiplexer 110, and the image processor 125 decodes and outputs an image signal received from the demultiplexer 110.

The audio signal and the video signal output from the audio processor 115 and the image processor 120 are respectively provided to the television 300 connected to the set top box 100. The television 300 displays an image corresponding to the video signal received from the set top box 100 and outputs an audio corresponding to the audio signal. In addition, the television 300 may receive a broadcast signal from an antenna connected to the television 300 without outputting the set top box, and output the video and audio corresponding to the broadcast signal, respectively.

Meanwhile, the input unit 125 generates an input signal according to a user's operation and provides the input signal to the controller 140. For example, the input unit 125 generates an input signal such as a channel change request for changing an input channel of the tuner 105 or a program execution request for executing a service program embedded in the set-top box 100. The input unit 125 may be a keypad provided integrally with the main body of the set top box 100, or may be a remote controller provided separately from the main body of the set top box 100.

The signal transceiver 130 is connected to the communication network 400 such as the Internet, and transmits and receives data with an external device connected to the communication network 400. Here, when the signal transmitting and receiving unit 130 is connected to the Internet, the set-top box 100 may provide an Internet service. In particular, the signal transceiver 130 is connected to the program service system 500 through the communication network 400 to receive data from the program service system 500.

Here, the program service system 500 includes an update server 510 and a download server 520. The update server 510 receives an update file for updating each program embedded in the set top box 100 from a service operation system (not shown) that provides each program. The update server 510 controls the download server 520 to provide the update file received from the service management system to the download server 520 and to provide the update file to the set top box 100. In addition, the update server 510 generates the program latest version information including the latest version information for each program and stores it in the download server 520.

The download server 520 stores the update file received from the update server 510 and stores the stored update file in the set top box 100 under the control of the update server 510. The program service system 500 illustrated in FIG. 1 is connected to one set top box 100, but the program service system 500 is connected to a plurality of set top boxes connected to the communication network 400 so as to provide an update file to each set top box. to provide.

The memory 135 stores data for driving the set top box 100 and programs driven in the set top box 100. Here, the program 100 driven in the set-top box 100 is a shell program driven as the main when the set-top box 100 is driven, and a service program provided by the set-top box 100, for example, a photo-related service. Programs, and movie programs that provide movie-related services.

The memory 135 stores an update file received from the signal transceiver 130, update list information indicating an update list corresponding to each program, and version information indicating version related information for each program. Here, the update list is generated for each program and is a list of update files corresponding to each program.

FIG. 2 is a diagram conceptually illustrating an example of version information stored in the memory illustrated in FIG. 1.

Referring to FIG. 2, the version information VF includes program name information F1, current version information F2, update version information F3, and meta file information F4.

Specifically, program name information F1 indicates the program name of each program.

The current version information F2 indicates the current version corresponding to each program, and the update version information F3 indicates the upgrade version corresponding to each program. The update version information F3 is generated when there is an update file downloaded by the set top box 100 at the previous booting and stored in the memory 135. That is, the update version information F3 is generated when the update is not made by using the downloaded update file.

The meta file information F4 is generated corresponding to the update version information F3 and indicates the address of a file storing the update list information generated corresponding to each program. That is, the meta file information F4 stores link information corresponding to update list information of each program.

When an update is made using the stored update file, the update version information F3 and the meta file information F4 are deleted, and the current version information F2 is updated with the update version information F3.

Referring back to FIG. 1, the memory 135 stores a file immediately before the update of each program, that is, a backup file, so that the update history corresponding to each program can be recognized.

The controller 140 generates a control signal for controlling the tuner 105, the voice processor 115, the image processor 120, and the memory 135 in response to the input signal received from the input unit 125, and generates the generated control signal. Provide a signal to the component. That is, when an input signal for changing a channel is received from the input unit 125, the controller 140 changes the current input channel into a channel corresponding to the input signal.

In particular, the controller 140 stores the update file received by the signal transceiver 130 in the memory 135 and updates the corresponding program using the update file. The controller 140 generates update list information of a program corresponding to the update file, stores the update list information in the memory 135, and stores the backup file in the memory 135 separately from other files. If an error occurs in the upgraded version of each program, the controller 140 returns the program to the previous version using the backup file.

In this way, the set-top box 100 may improve the quality of service since an error occurs in the upgraded version of the program or the program may be returned to the previous version at the request of the user.

3 is a flowchart illustrating a process of updating a program in a set-top box according to an embodiment of the present invention.

1 and 3, first, when the power of the set-top box 100 is turned on, the controller 140 drives a shell program and requests the update server 510 for the latest program version information. The signal transceiver 130 receives the program latest version information from the update server 510 through the communication network 400, and the controller 140 stores the received program latest version information in the memory 135 (step S610). .

Subsequently, the controller 140 determines whether there is update version information of the shell program by referring to the update version information F3 stored in the memory 135 (step S620).

In step S620, if the update version information corresponding to the shell program does not exist, the controller 140 extracts the latest version information of the shell program from the program latest version information, and the shell program from the version information VF (FIG. 2). After extracting the current version information, it is compared whether the current version of the shell program is the same as the latest version of the shell program (step S630).

In operation S630, if the current version of the shell program is different from the latest version, the controller 140 requests the update server 510 to update the file corresponding to the shell program through the signal transceiver 130. The signal transceiver 130 downloads the update file from the download server 520 through the communication network 400 (step S650).

Subsequently, the controller 140 determines whether to immediately execute an update of the shell program according to the downloaded update file or at the next boot (step S650).

In step S650, if the downloaded update file is an emergency file such as a patch file correcting a bug of a shell program or a file unrelated to execution of the shell program, for example, an image file and a resource file, the control unit 140 downloads the downloaded update. The update of the shell program is executed using the file (step S660).

On the other hand, if there is update version information of the shell program in step S620, the controller 140 executes an update of the shell program using the update file of the shell program stored in the memory 140 (step S660). In detail, the controller 140 extracts update list information of the shell program by referring to meta file information corresponding to the shell program from the version information VF (see FIG. 2). Subsequently, the controller 140 extracts the update file of the shell program stored in the memory 135 by referring to the update list information of the shell program and executes the update using the extracted update file. Here, the update file of the shell program stored in the memory 135 is an update file downloaded by the set top box 100 at the time of previous booting.

Following step S660, the controller 140 determines whether to reboot the set-top box 100 according to the type of update file of the shell program (step S670).

In step S660, if the update file is an emergency file or a file related to execution of a shell program, for example, an executable file or a dynamic linking library (DLL) file, the controller 140 reboots the set-top box 100 (step S680). Here, the emergency file is the file downloaded in step S640, and the execution-related file is the file downloaded from the previous boot.

On the other hand, in step S650, if the downloaded update file is an execution related file, the controller 140 stores the downloaded update file in the memory 135 and updates the update list corresponding to the shell program (step S690).

Following step S680 and step S690, the controller 140 updates the current version information, the update version information, and the meta file information corresponding to the shell program, and backs up the file before the update of the shell program (step S690). In detail, when the shell program is updated using the update file stored in the memory, the controller 140 updates the current version corresponding to the shell program with the update version, and deletes the update version information and the meta file information. On the contrary, when the downloaded update file is stored in the memory without executing the update of the shell program, the controller 140 stores the latest version information of the shell program as update version information corresponding to the shell program and updates the meta file. do.

When the current version of the shell program is the same as the latest version in step S630 and after step S710, the controller 140 executes the selected service program according to the user's operation (step S720).

4 is a flowchart illustrating a process of executing a service program shown in FIG. 2.

1 and 4, first, the controller 140 determines whether there is update version information corresponding to a currently executed service program by referring to update version information F3 stored in the memory 135 (step S721). ).

In step S721, if there is no update version information corresponding to the service program, the control unit 140 extracts the latest version information of the service program from the program latest version information, and from the version information VF (FIG. 2) After the current version information is extracted, it is compared whether the current version of the service program is the same as the latest version of the service program (step S722).

In operation S722, if the current version of the service program is different from the latest version, the controller 140 requests the update server 510 to update the file corresponding to the service program through the signal transceiver 130. The signal transceiver 130 downloads an update file corresponding to the service program from the download server 520 through the communication network 400 (step S723).

Subsequently, the controller 140 determines whether to immediately update the service program according to the downloaded update file or execute the update the next time the service program is executed (step S724).

In step S724, if the downloaded update file is a file unrelated to the execution of the service program, for example, an image file and a resource file, the control unit 140 executes the update of the service program using the downloaded update file (step S725). .

On the other hand, if there is update version information of the service program in step S721, the control unit 140 executes the update of the service program by using the update file of the service program previously stored in the memory 135 (step S725). Specifically, the controller 140 extracts update list information of the service program by referring to meta file information corresponding to the service program from the version information VF (see FIG. 2). Subsequently, the controller 140 extracts the update file of the service program stored in the memory 135 by referring to the update list information of the service program and executes the update using the extracted update file. Here, the update file of the service program stored in the memory 135 is an update file downloaded when the service program was previously executed.

In step S724, if the downloaded update file is an execution related file, the control unit 140 stores the downloaded update file in the memory 135, and updates the update list corresponding to the service program (step S726).

Following step S725 and step S726, the controller 140 updates the current version information, the update version information, and the meta file information corresponding to the service program, and backs up the file before the update of the service program (step S727). In detail, when the service program is updated using the update file stored in the memory, the controller 140 updates the current version corresponding to the service program to the update version, and deletes the update version information and the meta file information. On the contrary, in the case where the downloaded update file is stored in the memory without executing the update of the service program, the controller 140 stores the latest version information of the service program as update version information corresponding to the service program, and the meta file information. Update the.

Subsequently, the controller 140 executes the service program and outputs an image and an audio corresponding to the service program (step S728).

As such, the set top box 100 executes an update of the corresponding service program while the service program is executed. Also, if the update file is a file that requires a service program restart. The set-top box stores the update file and then executes the update of the service program the next time the service program is executed. Accordingly, the set top box 100 may shorten the time required for updating the service program.

In addition, the set-top box 100 separates the update of the shell program and the update of the service program, and executes only the update of the shell program at boot time, thereby preventing the boot time from being extended due to the update. Accordingly, the set top box 100 may improve the quality of service.

According to the present invention described above, the set-top box separates the update of the shell program and the update of the service program, and executes only the update of the shell program at boot time, thereby preventing the boot time from being extended due to the update. In addition, when updating a shell program, the set-top box can minimize the reboot due to the update file is divided into a file that requires a reboot and a file that does not require a reboot. Accordingly, the set top box can improve the quality of service.

In addition, when the service program is running, the update of the corresponding service program is executed, and the update file is a file requiring restart of the service program. The set-top box stores the update file and then executes the update of the service program the next time the service program is executed. Accordingly, the set top box can shorten the time required for updating the service program, thereby improving the quality of service.
