The present invention relates to a video device, and more particularly, to a video device having an upgrade function of a data broadcasting application and a control method thereof.

Recently, with the rapid development of digital broadcasting, not only video and audio signals are transmitted from broadcasting stations, but also various data are transmitted together. Such data broadcasting standards include a multimedia home platform (MHP), an open cable application platform (OCA), an advanced common application platform (ACAP), and the like.

In particular, the MHP is a new class based on Java, a network language of Sun Microsystems, Inc., which uses a data language corresponding to the Internet Protocol (IP) of a personal computer (PC). Means the standard used to send and receive.

1 is a block diagram illustrating a video device having a storage and execution function of data broadcasting according to the prior art. Hereinafter, a signal flow for executing an application of data broadcasting in a conventional video apparatus will be described with reference to FIG. 1.

As an example, the data broadcasting based on the MHP standard will be described below.

The tuner unit 102 tunes to a specific frequency received from a broadcasting station or the like, selects and extracts a specific radio wave.

The MPEG (Moving Picture Experts Group) decoder unit 103 analyzes a broadcast stream of a specific radio wave received from the tuner unit 102, and transmits video and audio related data to the display unit 108, and transmits the MHP Application OC ( Object Carousel) data is transmitted to the OC processing unit 105, and service information (Service Information) is transmitted to the SI detection unit 104.

The OC processor 105 decodes the MHP Application OC data transmitted in an OC (Object Carousel) manner so that the MHP engine 106 can use it.

However, the term OC (Object Carousel) refers to the object carousel (Object Carousel) method of the DSM-CC of the data transmission standard using a network, and means a bidirectional service transmission method of domestic digital cable broadcasting. do.

The RAM 107 may temporarily store MHP Application data decoded through the OC processing unit 105.

The SI detection unit 104 parses the tuning data of each program and the EPG data through the service information (SI) transmitted from the MPEG decoder unit 103.

The MHP engine 106 actually executes MHP application data through the display unit 108, and a Java virtual machine is mounted. The MHP engine 106 receives MHP Application data temporarily stored in the RAM 107 and controls the MHP engine 106 to be output through the display unit 108.

2 is a flowchart (flow chart) showing a control method of a video device having a function of storing and executing data broadcasting according to the prior art. Referring to FIG. 2, the procedure of executing an application of data broadcasting in a conventional video apparatus will be described.

The data broadcast (including the MHP data broadcast) may be switched to a channel for receiving (S201).

The data broadcast is loaded into the video device (S202).

After the loading operation S202 is completed, an icon indicating whether an application for data broadcasting can be executed is displayed (S203).

Here, the application of the data broadcast includes data broadcast associated with a game, an advertisement, an order screen, and the like.

When the icon is clicked, the application of the data broadcast is executed (S204).

After execution of the application for data broadcasting (S204) is completed, switching to another channel may be made (S205).

At this time, the data broadcast application stored in the RAM of the video device is erased and the data broadcast application received through the other channel is loaded (S206).

However, the above-described conventional video apparatus for receiving and displaying data broadcasts has the following problems.

First, the application of data broadcasting (including MHP data broadcasting, etc.) is changed and transmitted from time to time, but in the past, it is only stored temporarily in RAM, and even if the user wants to execute a preferred data broadcasting application, the preferred data again. There is a problem that the user must wait until the broadcast application is transmitted and cannot freely desire it at a desired time.

Secondly, in order to execute a data broadcast (including MHP data broadcast) application, the time to be loaded into the RAM through the OC processing unit is considerably long, which is very uncomfortable for the user.

Third, whenever a new version of a specific data broadcast application is available, the user has to directly search for an upgraded version of the specific data broadcast application.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a video device having an upgrade function of a data broadcasting application capable of executing a user's preferred data broadcasting application at any time, and a user thereof. It is to provide a control method.

It provides a video device having an upgrade function of the data broadcast application, characterized in that it comprises a control unit to execute.

The data broadcast preferably includes data broadcast according to the Multimedia Home Platform (MHP) standard.

The control unit tunes the tuner to be switched to the channel to which the data broadcast is transmitted, compares the version information of the data broadcasting application received through the tuner with the version information of the application previously stored in the memory unit, When the data broadcasting application is the upgraded version, it is preferable to store the upgraded application in the memory unit and control the execution of the upgraded application.

Preferably, the video apparatus further includes a display unit configured to output a screen for checking whether the upgraded version of the application is output and executed.

The control unit may store a channel from which the data broadcasting application previously stored in the memory unit has been downloaded, and then tune the tuner unit to switch to the channel, or transmit an application having the same name as the data broadcasting application previously stored in the memory unit. It is more desirable to tune the tuner section to any channel until the channel is found.

In order to achieve the above object, the present invention provides a method of controlling a video device that can receive and display data broadcast, comprising: storing a stream of a data broadcast application in a semi-permanent memory unit; Inputting a command to execute the stored data broadcasting application; determining whether an upgraded version of the application is transmitted through data broadcasting if the command is input; and If it is determined that the upgraded version of the application is transmitted through data broadcasting, receiving and executing the upgraded version of the application is executed, and the data broadcasting application has an upgrade function. It provides a control method of the device.

The data broadcast preferably includes data broadcast according to the Multimedia Home Platform (MHP) standard.

When the command is input, the step of determining whether the upgraded version of the application than the stored data broadcast application is transmitted to the data broadcast, tuning the tuner unit to switch to the channel to which the data broadcast is transmitted; Comparing the version information included in the stream of the data broadcasting application received through the tuner unit with the version information included in the stream of the application pre-stored in the memory unit, and the version of the prestored stream. If the information is a higher version, it is preferable to further comprise the step of determining that the upgraded version of the application is being transmitted through the data broadcast.

The control method of the imaging apparatus may further include displaying a screen for confirming whether or not to receive and execute the upgraded version of the application when the upgraded version of the application is transmitted through the data broadcast. It is preferable to be made.

Tuning the tuner unit to switch to a channel to which data broadcasting is transmitted may include storing a channel from which the data broadcast application previously stored in the memory unit has been downloaded, and then tuning the tuner unit to switch to the channel, or tuning to the memory unit. It is preferable to tune the tuner to an arbitrary channel until a channel through which an application of the same name as the stored data broadcasting application is transmitted is found.

Therefore, according to the present invention, even if the stream of broadcasted data is changed, the user's preferred data broadcasting application can be executed at any time, and when it is executed again, the loading time can be reduced, thereby significantly reducing the waiting time of the user. In addition, the pre-stored application is automatically upgraded, so that the user can always access the latest application.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

3 is a block diagram illustrating a video device having an upgrade function of a data broadcasting application according to the present invention. Referring to FIG. 3, a process of storing, upgrading, and executing a data broadcasting application in a component of a video device according to the present invention will be described below.

However, for the sake of easier understanding, "an embodiment in which a specific data broadcasting application is stored in a semi-permanent memory unit of a video device and then executed quickly (first embodiment)" and "prestored specific data" The embodiments in which the broadcast application is automatically upgraded (second embodiment) will be divided and described. Of course, the above embodiments may be implemented independently, or in combination, may be implemented in one technical spirit.

First embodiment

As shown in FIG. 3, the main components of the present invention are illustrated, and the basic components for receiving and displaying general video and audio broadcast signals are omitted. However, even though the illustration and detailed description of the basic components are omitted, those skilled in the art can understand the video device having the upgrade function of the data broadcasting application of the present invention through FIG.

In addition, although MHP (Multimedia Home Platform) data broadcasting is described by way of example, those skilled in the art will appreciate that it can be applied to other data broadcasting.

The imaging device 301 is a device in which the present invention is implemented and includes components to be described later. However, the video device 301 is not particularly limited. For example, the video device 301 may be a PDP television, an LCD television, or the like, and preferably, a digital receiver capable of receiving and displaying data broadcasts. It could be a television.

The data broadcast signal is decoded for use by the MHP engine 306 in the OC processing unit 305 and downloaded to the RAM 307. The MHP engine 306 outputs the data broadcast signal through the display unit 308.

In this case, a data broadcast signal temporarily downloaded to the RAM 307, that is, a signal for determining whether to store MHP application data in the memory unit 311 is input through the input unit 309.

The input unit 309 may be, for example, a remote controller or a local key attached to the video device 301.

When a signal determined to be stored is input through the input unit 309, the controller 310 may store MHP application data temporarily stored in the RAM 307 in the memory unit 311.

However, the memory unit 311 is not particularly limited, but is preferably a medium that can be semi-permanently stored, such as a personal video recorder (PVR), a universal serial bus (USB) memory, and the like. Of course, as in the prior art, a temporarily downloadable RAM may not be the memory part of the present invention.

The controller 310 receives an application information table (AIT) table from the SI detector 304 even before MHP application data is output, and refers to the AIT table and downloads the MHP application downloaded to the RAM 307. The type of data may be determined to determine whether to store the data in the memory unit 311.

However, the AIT table means information on the MHP Application extracted through the SI detector 304. For example, information related to content such as a game or advertisement, or information for determining whether the application is a channel bound application or a channel unbound application that is independent of the broadcast program. .

When a signal for executing MHP application data stored in the memory unit 311 is input through the input unit 309, the controller 310 extracts MHP application data stored in the memory unit 311. Control to be output through the display unit 308.

Second Embodiment

On the other hand, the embodiment will be described in detail with respect to the video device for automatically upgrading the version of the pre-stored data broadcasting application.

The command to display a list of pre-stored data broadcasting applications may be input through the input unit 309. In some cases, the number of data broadcasting applications stored in the memory unit 311 may be singular or plural.

4A is a diagram illustrating an example of a display screen of an imaging apparatus according to the present invention. For example, when a command to display a list of pre-stored data broadcasting applications is input through the input unit 309, under the control of the controller 310, the display unit 308 is as shown in FIG. 4A. Similarly, a list of previously stored data broadcasting applications is displayed. After checking the displayed screen, the user can select a specific data broadcasting application to be executed.

When a command to execute a specific data broadcast application is input again through the input unit 309, the controller 310 may transmit an upgraded version of the application to data broadcast than the specific data broadcast application stored in the memory unit 311. It is determined whether it is currently being sent.

As a result of the determination of the controller 310, if the upgraded version of the application is currently transmitted through the data broadcast, the controller 310 controls the display unit 308, as shown in FIG. After upgrading the application you want to run, you can print a message to confirm whether you want to run it. This is a technical feature that considers both the user's preference for the latest version and the user's desire to run the previous version immediately.

If the user who checks the displayed screen inputs a command for upgrading a specific application through the input unit 309, the controller 310 may input the upgraded specific application that is currently being sent to the memory unit 311. After the storage process is completed, the upgraded specific application is executed. For example, it may be output through the display unit 308.

However, the control unit 310 will be described in more detail with respect to the method of checking whether the upgraded specific application is transmitted to the data broadcast as follows.

The control unit 310 separately stores a channel that has previously downloaded a data broadcasting application stored in the memory unit 311, and when a command for executing a previously stored specific application is input through the input unit 309, the tuner unit 302 can be controlled to allow automatic tuning to the memorized channel. This generally takes into account that the same application can continue to be broadcast on the same channel.

Alternatively, the controller 310 controls the tuner 302 to tune to an arbitrary channel until a channel through which an application having the same name as the specific data broadcast application previously stored in the memory 311 is transmitted is found. You can. For example, when the name of a specific data broadcasting application pre-stored in the memory unit 311 is "Tetris", and a search is made for a channel on which an application named "Tetris" is transmitted, the control unit 310 is configured as the tuner unit. 302 is controlled to tune to the channel on which the application named "Tetris" is sent.

The controller 310, which searches for a channel through which an application having the same name as that of the previously stored application is transmitted, compares version information and determines whether to download the application transmitted from the searched channel.

Since the stream of the application pre-stored in the memory unit 311 includes version information, and the version information is also included in the stream of the application transmitted from the searched channel, the controller 310 The version information is compared and when the version information included in the stream of the application transmitted from the searched channel is the latest version, the transmitted application is stored in the memory unit 311.

The display unit 308 may execute the newly stored latest version of the application.

However, the application of the data broadcast herein refers to data broadcast associated with a game, advertisement, order screen, and the like.

When the icon is clicked, the application of the data broadcast is executed (S504).

In operation S505, it is determined whether the application is stored in the memory unit 311. Of course, the determination may be made after the application is executed, or even before the application is executed, the determination may be made by referring to the AIT table.

If it is determined in operation S505 that it is determined not to store in the memory unit 311, when switching to another channel, the application of the data broadcast stored in the RAM 307 is erased and the data broadcast of the other channel is deleted. The application may be uploaded (S507).

On the other hand, when it is determined in operation S505 that the storage unit 311 is determined to store the data broadcast application stored in the RAM 307, the storage unit 311 may store the application unit in operation S506. . Then, the step S507 can be executed.

However, the memory unit 311 is not particularly limited, but is preferably a medium that can be semi-permanently stored, such as a personal video recorder (PVR), a universal serial bus (USB) memory, and the like. Of course, as in the prior art, a temporarily downloadable RAM may not be the memory part of the present invention.

It is determined whether the upgraded version of the selected specific data broadcasting application is transmitted through data broadcasting (S603).

As a result of the determination (S603), if the upgraded version of the selected specific data broadcasting application is not transmitted, the existing application previously stored in the memory unit is executed (S606).

As a result of the determination (S603), if the upgraded version of the selected specific data broadcasting application is transmitted, the upgraded version of the application is downloaded (S604). Of course, before the download, as shown in Figure 4b, it is also possible to display a screen to confirm whether to download the upgraded version of the application.

When the download step (S604) is finished, the downloaded upgrade version of the application is executed (S605).

The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.

And, the above-mentioned numerical value is a preferred embodiment or merely an example, the scope of the present invention is not limited to the numerical values, and as can be seen in the appended claims, Modifications are possible by those skilled in the art and such modifications are within the scope of the present invention.
