1 is a block diagram showing the configuration of a video device capable of receiving external data according to the present invention.

2 is a diagram illustrating a first embodiment of a video device capable of receiving external data according to the present invention.

1 and 2, when an image device according to the present invention receives various data from a plurality of external devices, an embodiment of providing a screen for easily selecting specific data of user preference is provided. The explanation is as follows.

As shown in FIG. 1, the imaging apparatus 100 according to the present invention includes a USB connector 101, a memory slot connector 102, a USB host 103, a memory card controller 104, and an external device recognition unit 105. ), OSD unit 106, MPEG4 decoding unit 107, control unit 108, SDRAM 109, flash memory 110, PVR data transmission and reception unit 111, PVR controller 112, mixing unit 113 , MPEG decoding unit 114, and display module unit 115.

The video apparatus 100 may be, for example, a digital television (DTV), a personal video recorder (PVR), a digital video recorder (DVR), or the like.

In order to recognize an external device, the memory card controller 104, the USB host 103, and the external device recognition unit 105 are added.

However, the external device may be, for example, a universal serial bus (USB) device, a memory slot, or the like.

The controller 108 reads data recognized by the external device recognizing unit 105.

The controller 108 stores the read data in the SDRAM 109, and controls a user interface to be reproduced by the OSD (On Screen Display) 106. The MPEG4 decoding unit 107 controls the playback.

However, the SDRAM (Synchronous Dynamic Random Access Memory) 109 is just an example, and the present invention may be implemented using another storage unit.

Meanwhile, the MPEG4 decoding unit 107 decodes data compressed by the MPEG4 method and mainly decodes A / V data applied from an external device rather than a broadcast signal.

The mixing unit 113 mixes the image data applied from the MPEG4 decoding unit 107 and the OSD data applied from the OSD unit 106 and transmits the mixed data to the MPEG decoding unit 114. .

The MPEG decoding unit 114 decodes the data mixed by the mixing unit 113 again to make it possible to output through the display module unit 115.

However, the MPEG decoding unit 114 may be, for example, an MPEG2 decoder, and is mainly responsible for decoding a digital TV broadcast signal.

On the other hand, when the video device 100 performs a personal video recording (PVR) function, the PVR controller 112 controls the PVR data transmission / reception unit 111 to read previously stored data.

The PVR controller 112 again controls the MPEG decoding unit 114 so that the loaded data can be reproduced.

In particular, with reference to the present invention, it will be described in more detail as follows.

When a plurality of external devices are connected to the connectors 101 and 102 of the video device 100, the external device recognition unit 105 first determines whether any external device is connected to the video device 100. .

The external device may be, for example, a memory slot, a USB device, or the like, and may be another device capable of transmitting data.

In addition, although only one USB connector is illustrated in FIG. 1, the imaging apparatus 100 may have two or more USB connectors.

The controller 108 controls the memory card controller 104 and the USB host 103 to determine a specific display type to which files stored in a memory in each external device belong.

The display type includes, for example, a video display type (representative example, movie, etc.), a still image display type (representative example, pictures, etc.), a music display type, and the like.

The control unit 108 may determine the specific display type to which the files stored in the memory in each external device belong by using the extension name of each file.

For example, the extension name of a specific file may be avi. In the case of mpg, wmv, etc., the specific file is regarded as a video display type.

On the other hand, when the extension name of a specific file is mp3, wma, asf, or the like, the specific file is considered to be a music display type.

On the other hand, when the extension name of a specific file is jpg, bmp or the like, the specific file is considered to be a still image display type.

Accordingly, the controller 108 may check information on a display type of files that are currently connected to an external device and stored in a memory of each external device.

In addition, the controller 108 controls the OSD unit 106 by using the identified information to output a display screen as shown in FIG. 2.

That is, as shown in FIG. 2, an external device having a file corresponding to a specific display type and an external device not having a file corresponding to a specific display type are displayed differently.

In FIG. 2, the memory card and the USB 2 device have files of a video display type (typical example, Movie, etc.), a still image (typical example, Photo, etc.) display type, a music display type, and the like. The memory card and USB 2 device are shown.

On the other hand, the USB 1 device does not have any files of the video display type (typical example, Movie, etc.), the still image (typical example, Photo, etc.) display type, and the music display type. The USB 1 device is displayed.

Of course, the white and the gray are just examples, and if the external devices are separately displayed according to whether a file of a specific display type is stored, all of them belong to the scope of the present invention.

Furthermore, an external device that does not store a file of a specific display type may be displayed in gray letters and designed so that a user cannot select it.

Therefore, the user can check only the display screen shown in FIG. 2 without any special procedure and can quickly and easily check whether there are any display type files in which external device among a large number of external devices. have.

3 is a diagram illustrating an example of an internal data structure of a system download file according to the present invention.

Figure 4 is a more simplified view of an example of the internal data structure of the system download file according to the present invention.

FIG. 5 is a diagram illustrating a second embodiment of a video device capable of receiving external data according to the present invention.

Hereinafter, an embodiment in which the video device according to the present invention receives a system download file and newly drives the video device according to the transmitted file will be described with reference to FIGS. 3 to 5 (see FIG. 1). .

However, the system download file used in the present specification means software that is directly or indirectly related to system driving of the video apparatus, upgraded software, or equivalent software.

In the present invention, as shown in Fig. 3, the system download file includes information defining a name of the file, information identifying whether the file is a system download file, and a version number of the system download file. We want to insert information that we define.

For example, in a data structure constituting an arbitrary file, when the value of a specific position is "0xFFFF", the control unit 108 or the like of the video apparatus 100 indicates that the arbitrary file is a system download file. I think that. Of course, the numerical value is only one example, it is also possible to design a different number of bytes.

On the other hand, in the data structure constituting an arbitrary file, when the value of a specific position is not "0xFFFF", the control unit 108 or the like of the video apparatus 100 indicates that the arbitrary file is a system download file. You can judge that it is not. For example, movie files, music files, picture files, and the like.

That is, as shown in FIG. 4, it is a feature of the present invention to define and insert a file name, information identifying whether a system download file, a version number, and the like are inserted in a header portion of a specific file.

The version number can be used to display the version number of the system download file. Therefore, by using the version number, even if the file name is the same and the system download file is not downloaded, only the latest version of the file is downloaded. There is a real benefit to download.

The controller 108 may control the OSD unit 106 to display information on the system download file received through the USB connector 101 as shown in FIG. 5.

Receiving a system download file via a USB connector rather than a PC is also a feature of the present invention.

Further, the controller 108 stores the specific file determined as a system download file, in the flash memory 110, the SDRAM 109, or the like.

The controller 108 automatically reboots the video device 100 and controls the video device system 100 to operate according to the stored specific file.

Therefore, when using the file having the data structure shown in Figure 3 or 4, and receiving the file through the USB connector 101, there is an excellent effect in terms of time and convenience compared to the conventional.

This is because, in order to insert a system download file into a video device, a file previously stored in a PC through an RS-232C cable is transferred to the video device, which requires a lot of time and requires a PC to be driven. to be.

In addition, when using the RS-232C cable, due to the processing speed of the UART (Universal Asyncronous Receiver Transmitter) device according to the flash memory capacity, there was a problem that the time is further delayed.

According to the sequential description as follows.

However, in the above description of FIGS. 1 and 2, since the operation of the video apparatus has been sufficiently described, a detailed description thereof will be omitted.

The imaging apparatus according to the present invention preferentially searches whether the external apparatus is connected to the imaging apparatus (S601).

It is determined whether there is an external device connected to the video device (S602).

As a result of the determination (S602), when there is an external device connected to the video device, the specific type of the external device is checked and stored in the memory (S603).

For example, the video device may be a USB device, a memory card, or the like.

The type of the file stored in the external device connected to the video device is determined (S604).

The extension name of the file is used to determine whether the file is a video display type (S605).

However, a video display type file may have an extension name such as avi, mpg, wmv, or the like.

As a result of the determination (S605), when the specific file is a video display type file, as shown in FIG. 2, an external device storing the specific file is displayed in white in a movie list, so that the user Design to be selectable (S606).

On the other hand, when the determination result (S605), if the specific file is not a video display type file, it is determined whether the file is a music display type (S607).

However, the file of the music display type may have an extension name such as mp3, wma, asf, or the like.

As a result of the determination (S607), when the specific file is a file of a music display type, as shown in FIG. 2, an external device storing the specific file is displayed in white in a music list, so that the user It is designed to be selectable (S608).

On the other hand, when the determination result (S607), the specific file is not a file of the music display type, it is determined whether the file is a still image display type (S609).

However, a file of the still image display type may use jpg, bmp, or the like as an extension name.

As a result of the determination (S609), when the specific file is a still image display type, as shown in FIG. 2, an external device storing the specific file is displayed in white in the photo list, and the user selects it. It is designed to be possible (S610).

Meanwhile, as a result of the determination (S609), when the specific file is not a file of the still image display type, as shown in FIG. 2, all the external devices are displayed in gray, so that the user cannot design the selected file (S611). .

Of course, the steps S605, S607, S607 can be implemented even if the order is changed to each other.

Hereinafter, an embodiment in which the video device according to the present invention receives a system download file and newly drives the video device according to the transmitted file will be described with reference to FIG. 7 in order of time. .

The video device according to the present invention reads a specific file from an external device (S701).

It is determined whether the extension name of the read specific file is 'glf' (S702).

In general, the system download file is considered to use 'glf' as the extension name.

As a result of the determination (S702), if the extension name is not 'glf', it is not a system download file, so that the movie file, the music file, and the photo file are normally played (S703).

On the other hand, in the determination result (S702), when the extension name is 'glf', it is determined whether the specific file is a system download file by using information identifying whether the file is a system download file included in the specific file. (S704).

Although FIG. 7 illustrates both S702 and S704, the present invention may be implemented by only S704.

However, when both the step S702 and the step S704 are executed, double checking whether the file is a system download file has the advantage of lowering the possibility of error.

As a result of the determination (S704), if the specific file is not a system download file, the movie file, the music file, and the photo file are normally played (S703).

On the other hand, if the determination result (S704), the specific file is a system download file, it is stored in a flash memory or the like (S705).

After the automatic reboot, the video device is controlled to be driven according to the stored system download file (S706).
