1 is a block diagram showing a configuration of a preferred embodiment of a video system according to the present invention.

Referring to FIG. 1, an image system 100 according to the present invention includes a recording / reproducing apparatus 110, external resources 112, 114, 120, 130 and 140, and a repeater 150. Here, the external resources 112, 114, 120, 130 and 140 may be divided into a global resource 140 and local resources 112, 114, 120 and 130. The global resource 140 is a server located on a wide area network (WAN). The global resource 140 may provide the web disk service to the recording / playback device 110. The local resources 112, 114, 120 and 130 may include information communication devices 120 and 130 and memory devices such as a home server, a PC, a notebook computer, a mobile phone, a PDA, ), And a USB flash memory 114, which are connected to the recording / reproducing apparatus 110 through a serial bus interface. The recording and / or reproducing apparatus 110 and the external resources 112, 114, 120, 130 and 140 may be constituted of a plurality of recording and reproducing apparatuses 110 and 120, One home network can be formed. In addition, the local resources 120 and 130 may be the recording / reproducing apparatus 110. [

In addition, the image system 100 according to the present invention further includes a remote controller 111 capable of transmitting / receiving data to / from the recording / reproducing apparatus 110 remotely or wirelessly. The user can control the recording / reproducing apparatus 110 remotely or wirelessly via the remote controller 111. [

The recording / reproducing apparatus 110 encrypts the input initial authentication information to generate device authentication information, and transmits the generated device authentication information to the local resources 120 and 130 to request a connection. The recording / reproducing apparatus 110 can directly connect to the local resources 120 and 130 in a wired or wireless manner according to a standard protocol and can access the local resources 120 and 130 through the repeater 150. Here, the repeater 150 plays a role of relaying data transmission / reception between the recording / reproducing apparatus 110 and the local resources 120 and 130. The recording and / or reproducing apparatus 110 may be a standard protocol such as an IEEE802.11 communication system, an IEEE802.11n communication system, an IEEE802.11g communication system, an IEEE802.15.4 communication system, a WiFi communication system, an Ethernet communication system, a WCDMA communication system, Method or the like can be used.

The local resources 120 and 130 receive and decrypt the transmitted device authentication information. The local resources 120 and 130 receive authentication authentication information from the user and encrypt the input authentication authentication information to generate authentication information. Here, the local resources 120 and 130 may allocate a storage area or a memory area for storing video data by the recording / reproducing apparatus 110. That is, the local resources 120 and 130 can allocate a storage area for the DVR (Digital Video Recorder) to be used by the recording / playback apparatus 110. For example, the local resources 120 and 130 may set the shared directory in the storage area.

 The local resources 120 and 130 determine whether to connect the recording / playback apparatus 110 based on the authentication authentication information received from the decrypted apparatus authentication information. When the connection is approved, the local resources 120 and 130 record the storage area or the memory area allocated by the recording / playback apparatus 110 in order to store the video data in the memory of the local resources 120 and 130, Playback apparatuses 120 and 130 so that the recording / reproducing apparatuses 110 can mount them. Accordingly, since the image system 100 according to the present invention performs mutual authentication between the devices constituting the image system, unauthorized access can be prevented, and the authentication key used at the time of authentication is encrypted, Key leakage can be prevented, and mutual authentication can be performed in a secure manner.

The recording / reproducing apparatus 110 can mount a storage area provided by the local resources 120 and 130 through a protocol such as a network file system (NFS) or a common internet file system (CIFS). That is, in order to mount the storage area of the local resources 120 and 130, the recording / playback apparatus 110 may store the storage area of the storage area of another device connected through the network according to the type of the operating system (OS) Or a protocol that has been newly implemented can be used.

Here, the network file system (NFS) is a distributed file sharing system software for sharing a file or a file system on another computer connected to an information communication network such as a local area network (LAN) And the operating system (OS) are distributed to computers in different environments. A file system on another computer with Network File System (NFS) can be accessed as if it were a local file on your computer, so you do not have to manipulate files after you transfer files. It is also possible to use a file of another system without being aware of the storage location of the file. However, in connection with a system having a different code system, it is necessary to consider sign conversion and the like.

Common Internet File System (CIFS) is a protocol that allows programs to make requests to files or services on a remote computer over a network. A client program makes a request to a server program that is usually located on another computer, such as requesting access to a file on a server computer, or forwarding a message to a program. The server accepts the request and returns a response accordingly.

In addition, the recording / reproducing apparatus 110 calculates error confirmation information on the storage areas of the mounted local resources 120 and 130, and stores the mounted local resources 120 and 130 on the basis of the error confirmation information and the stored error confirmation information, 130 in the storage area. When the storage area of the local resources 120 and 130 is first mounted or the video data or the like is recorded in the storage areas of the local resources 120 and 130, the recording / reproducing apparatus 110 calculates and stores error confirmation information . When the storage area of the local resources 120 and 130 is mounted, the recording / reproducing apparatus 110 calculates error check information and compares the error check information with the stored error check information. If the calculated error check information does not match the stored error check information, the recording / reproducing apparatus 110 outputs a message about the error and can remove the errored file. The recording / playback apparatus 110 may start the DVR service by using the storage area of the mounted local resources 120 and 130 as a repository.

For example, the recording / reproducing apparatus 110 calculates error check information by CRC calculation on the DVR data size. In this case, the recording / reproducing apparatus 110 can check whether the CRC calculated is consistent with the stored CRC, and whether the data or the file stored in the storage area of the mounted local resources 120 and 130 is transformed or not. Accordingly, the image system 100 according to the present invention checks whether the image data stored in the device storing the image data is arbitrarily deformed and removes the arbitrary deformed image, thereby preventing malfunction and malfunction of the recording / reproducing apparatus 110 .

In addition, the recording / reproducing apparatus 110 modifies the mode of the data or the file stored in the storage area of the mounted local resources 120 and 130. Here, the mode of the file includes a read mode, a hidden mode, a read / hide mode, and a write mode. Here, read mode is a mode in which a file is read only and can not be read and modified. Hidden mode is a mode in which a file is hidden so that it is not displayed on a program displaying a file system such as a window explorer. A read mode and a hidden mode are simultaneously applied, and a write mode means a mode in which a file can be modified. Accordingly, the image system 100 according to the present invention changes the file attributes of the image data stored in the storage areas of the local resources 120 and 130 to the hidden or read-only attributes to prevent unauthorized users from accessing and random access And can prevent arbitrary modifications.

2 is a block diagram showing a configuration of a preferred embodiment of a recording / reproducing apparatus according to the present invention.

2, the recording / reproducing apparatus 200 includes a receiving unit 201, a demodulating unit 202, a demultiplexing unit 203, a decoding unit 204, a display unit 205, a control unit 206, A playback control unit 207, a device interface unit 208, a user interface unit 209, a format converter 210 and a remote signal receiving unit 211.

3 is a diagram showing a preferred embodiment of the apparatus interface portion.

Referring to FIG. 3, the device interface unit 208 transmits and receives data to and from the external resource 250. The device interface unit 208 for this purpose includes a serial bus interface unit 310 and a communication interface unit 320.

The serial bus interface unit 310 is connected to a local resource 301 to which external storage media 112 and 114 connected by a serial bus interface belongs and interfaces data transmission / reception with the connected local resources 301. Here, the serial bus interface unit 310 may be implemented on a USB (Universal Serial Bus) or IEEE 1394 basis. When connected to the serial bus interface unit 310, the local resource 301 provides a storage area to the recording / reproducing apparatus 200. Then, the recording / reproducing apparatus 200 can perform the DVR function based on the storage area provided by the local resource 301. [ In particular, when the recording / reproducing apparatus 200 does not have an internal storage area, the user can easily use the DVR function of the recording / reproducing apparatus 200 by attaching the local resource 301 to the recording / reproducing apparatus 200 .

When the local resource 301 is connected to the recording / reproducing apparatus 200 and provides the recording area to the recording / reproducing apparatus 200, the recording / reproducing apparatus 200 activates the DVR mode, And stores the image data in one storage area 200. Here, the DVR mode may be activated automatically or may be activated by a user's selection. When the DVR mode is activated, the functions related to the DVR, for example, time shift function can be performed. If the DVR mode is disabled, the function related to the DVR is not performed. For example, when the DVR mode is deactivated, even if the DVR-related execution menu items are selected, the corresponding function is not performed. Even if a DVR-related command is inputted through an input device such as the remote controller 111, the corresponding function is not performed.

The communication interface unit 320 interfaces data transmission / reception with the local resource 302 and the global resource 303. Here, the local resource 302 refers to a digital device equipped with a recording / playback apparatus and a storage medium located on a local area network (LAN), and the global resource 303 is a server located on a wide area network (WAN) it means.

The communication interface unit 320 may include an Ethernet module, a Bluetooth module, a short-range wireless Internet module, a portable Internet module, a home PNA module, an IEEE1394 module, a PLC module, a home RF module, and an IrDA module. However, the interface of the communication interface unit 320 is not limited thereto. For example, the communication interface unit 320 may comprise an Ethernet module (LAD Card), and may interface with the local resource 302 and the global resource 303 via wired connection. As another example, the communication interface unit 320 may be a short-range wireless Internet module (wireless LAN card) and may interfere with data transmission / reception between the local resource 302 and the global resource 303 wirelessly. When the communication interface unit 320 is configured as a local wireless Internet module (wireless LAN card), the local resource 302 and the global resource 303 can be connected through the relay 150. [

 As another example, the device interface unit 208 may include a USB interface and a USB dongle to communicate with the local resource 302 and the global resource 303 through a USB dongle.

When the local resource 302 approves the connection request for the connection to the recording / playback apparatus 200 and provides the storage area to the recording / playback apparatus 200 so that the recording / playback apparatus 200 can access the DVR mode And stores the image data in the storage area provided by the local resource 302. [ Here, the DVR mode may be activated automatically or may be activated by a user's selection. When the DVR mode is activated, the functions related to the DVR, for example, time shift function can be performed. If the DVR mode is disabled, the function related to the DVR is not performed. For example, when the DVR mode is deactivated, even if the DVR-related execution menu items are selected, the corresponding function is not performed. Even if a DVR-related command is inputted through an input device such as the remote controller 111, the corresponding function is not performed.

In the recording / reproducing apparatus 200, the receiving unit 201 may include one or more tuners, and receive content from at least one of terrestrial, satellite, and cable through a tuner. The tuner may be provided for each of a broadcast source, for example, a terrestrial wave, a cable, and a satellite, or may be an integrated tuner. If the tuner is a terrestrial broadcast tuner, it may include at least one digital tuner and an analog tuner, or may be a digital / analog integrated tuner. The tuner tunes a broadcast signal of a channel selected by a user among terrestrial broadcast contents transmitted through an antenna, that is, a broadcast signal, and outputs the tuned signal to the demodulator 202. The demodulator demodulates the inputted broadcast signal in the reverse of the modulation scheme.

The receiving unit 201 may receive the content through the Internet network. Also, the receiving unit 201 may include one or more external input / output terminals, and may receive contents from an external device through an external input / output terminal. The external input / output terminal may be, for example, an AV terminal, a component terminal, an RGB terminal, a DVI (Digital Visual Interface) terminal, or an HDMI (High-Definition Multimedia Interface) terminal. An external device such as a DVD player, a digital TV, a satellite set-top box, a cable set-top box, or a PC can be connected to the AV terminal, the VCR, and the analog TV.

The format converter 210 directly outputs or downconverts the high-definition content received from the external device to the demultiplexing unit 203 and outputs the down-converted content to the storage / reproduction control unit 207. That is, when the display is selected, the resolution of the external high-definition content is directly output to the demultiplexer 203 without being down-converted. When the recording is selected, the resolution of the external high-definition content is down- do. There are various methods for downconverting the high-definition content in the format converter 210. [ Also, the resolution of the down-converted content may be changed according to the down-conversion method, and in the present invention, down-conversion is performed to the 480i (i is interlaced) CCIR656 format. If the content inputted from an external device is an analog format, the format converter 210 outputs the digital content to the demultiplexing unit 203 or the storage / reproduction control unit 207.

The broadcast signal demodulated in the demodulator 202 is in the form of a transport stream and is output to the demultiplexer 203. The demultiplexer 203 demultiplexes the broadcast signal and outputs the demultiplexed signal to the decoder 204. [ The demultiplexer 203 separates the broadcast signal into an audio elementary stream ES and a video elementary stream ES and outputs them to respective decoders of the decoding unit 204. [ In a case where a plurality of programs are multiplexed on one channel, only the broadcast signal of the program selected by the user can be selected and divided into the video element stream and the audio element stream. If the demodulated broadcast signal includes a data stream or a system information stream, the demodulated broadcast signal is also demultiplexed by the demultiplexer 203 and transmitted to the corresponding block. Since this portion is not a feature of the present invention, detailed description will be omitted.

The decoding unit 204 includes an audio decoder and a video decoder and decodes the broadcasting signal output from the demultiplexing unit 203 or the broadcasting signal reproduced through the storage / reproduction control unit 207 using respective decoding algorithms And outputs it to the display unit 205.

On the other hand, if at least one of the DVR mode and the DVR mode is set and the DVR mode is active and the DVR mode is set to the DVR mode via the device interface 208 of the DVR 200 , And the storage / reproduction control section 207 receives the demodulated signal from the demodulation section 202. [

The storage / reproduction control unit 207 transmits a signal output from the demodulation unit 202, a signal output from the demultiplexing unit 203, and a signal output from the format converter 211 to an external resource 250 in a storage area. At this time, if the recording is instantly performed, it is stored in the semi-permanent storage area of the storage medium among the storage areas provided by the external resource 250, and in the time shift mode, it is stored in the time shift storage area of the storage medium among the storage areas provided by the external resource 250 As an embodiment.

The storage / reproduction control unit 207 may read the broadcast signal stored in the storage area provided by the external resource 250 according to the user's reproduction request, and output the read broadcast signal to the demultiplexing unit 203 or the decoding unit 204 . The broadcast signal stored in the storage area provided by the external resource 250 may be in the form of a transport stream compression-encoded at the transmission side. In this case, the decoding unit 204 decodes the compression-encoded transport stream with each decoding algorithm, and outputs the decoded transport stream to the display unit 205.

The storage / reproduction control unit 207 may encode and output a broadcast signal output to a storage area provided by the external resource 250. In this case, the storage / reproduction control unit 207 must be able to decrypt the broadcast signal that is encrypted and reproduced in the storage area provided by the external resource 250. Here, the encryption / decryption operation may consist of software, hardware, firmware, middleware, or a combination of at least two of such.

The recording / reproducing apparatus 200 according to the present invention may include a receiving unit 201 and a demodulating unit 202 to serve as a broadcasting receiver. In another embodiment, the recording / 200 may be implemented as a device that receives a demodulated broadcast signal from a broadcast receiver and records and reproduces the demodulated broadcast signal. Also, the recording / reproducing apparatus 200 may be a digital TV, a DVR ready digital TV, and an IPTV.

The remote signal receiving unit 211 transmits / receives a control signal for controlling the remote controller 111 and the recording / reproducing apparatus 200. The control unit 209 controls the recording / reproducing apparatus 200 based on the control signal received by the remote signal receiving unit 211. Further, the control unit 209 calculates a control signal to request the user for specific information or command, and outputs the calculated control signal to the remote signal receiving unit 211. Then, the remote signal receiving unit 211 transmits the control signal output from the control unit 209 to the remote controller 111. The remote controller 111 receives the signal transmitted from the remote signal receiver 211 and displays a message related to the command or information specific to the user on the basis of the received control signal.

Here, the operations of the control unit 206 and the storage / playback control unit 207 may be any one of hardware, firmware, middleware, and software, or may be a combination of at least two of them. In addition, the control unit 206 may serve as the storage / reproduction control unit 207, and in this case, the storage / reproduction control unit 207 may be omitted. The control unit 206 and the storage / reproduction control unit 207 may be implemented as one integrated module 210 using hardware and firmware.

4 is a diagram showing a menu screen for receiving access information and authentication information for a global resource.

Referring to FIG. 4, the storage / reproduction control unit 207 requests the user for access information and authentication information for the global resource 303 through the menu screen 400. Herein, the connection information means information on an address for connection to the global resource 303. The user can input any one of an IP address, a DNS (domain name system) name and a URL (uniform resource locator) into the input box 410 as access information for the global resource 303 through the menu screen 400 . Also, the user can input the IP address and the port number into the input box 410 together with the access information to the global resource 303.

The authentication information means information required to log in to the global resource 303. The user can input a user ID and a password into the input box 420 and the input box 430 as authentication information for the global resource 300 through the menu screen 400. [

When the connection information and the authentication information are input from the user, the storage / reproduction control unit 207 checks the state of the global resource 303 based on the input connection information and authentication information. Here, the storage / reproduction control unit 207 checks the state of the global resource based on at least one of a response status, a connection status, a communication speed, and a storage area capacity. That is, the storage / playback control unit 307 checks whether the global resource 303 responds or not by performing a ping test while changing the size of the transmission packet to the global resource 303, , It is determined that the communication with the global resource 303 is in a normal state, and when the rate is not suitable for storing the broadcast content, it is judged to be in an abnormal state. Here, the communication speed may be set according to the speed at which the speed recording / playback apparatus for storing the broadcast content receives the broadcast content from the broadcast station. For example, in the case of a broadcast service conforming to the Advanced Television Systems Committee (ATSC) It is preferable to set the rate for storing the data to 19.3 Mbps.

The storage / playback control unit 207 may attempt to access the global resource 303 to check whether the authentication information input by the user is erroneous or the capacity of the storage area provided by the global resource 300. [ The storage / reproduction control unit 207 can determine that the state of the global resource 303 is in an abnormal state when the user should not log in to the global resource 303 due to an error of the authentication information input by the user. When the login is made to the global resource 303, the storage / reproduction control unit 207 checks the capacity of the storage area provided by the global resource 303, and if the size of the storage area provided by the global resource 303 is If it is smaller than the preset request value, the state of the global resource 303 can be determined as an abnormal state. Here, the preset request value may be determined according to the size of the broadcast content for recording, and may be modified by the user.

When the state of the global resource 303 is abnormal, the storage / reproduction control unit 207 causes the user interface unit 209 to output to the user a message informing the fact that the global resource 303 is in an abnormal state . Here, the message may include a statement as to why it is determined to be in an abnormal state. That is, if the authentication information is an error, the message may include a phrase that the user ID is erroneously input.

In addition, when the state of the global resource 303 is abnormal, the storage / reproduction control unit 207 may output a message requesting the user to re-enter the access information and the authentication information of the global resource 303 .

The storage / reproduction control unit 207 can access the global resource 303 through FTP (File Transfer Protocol) or HTTP (hypertext transfer protocol). When the storage / reproduction control unit 207 uses FTP to access the global resource 303, the global resource 303 may be a server that provides an FTP service. The storage / playback control unit 207 can store the broadcast content through commands such as get, put, and ls provided by the FTP, download the broadcast content, and store the capacity of the storage area provided by the global resource 303 A list of stored broadcast contents can be confirmed.

When the storage / playback control unit 207 uses HTTP to access the global resource 303, the global resource 303 may be a server that provides a Web disk service. The storage / reproduction control unit 207 can store the broadcast content through the command provided by the global resource 303 and download the broadcast content. The storage / reproduction control unit 207 stores the capacity of the storage area provided by the global resource 303, Can be confirmed. In this case, the command provided by the global resource 303 can be determined in advance between the receiver company and the web disk provider, and when the recording / playback apparatus according to the present invention accesses the global resource 303 for the first time It is possible to download information on the command provided by the global resource 303 or a program for using the command provided by the global resource 303 from the global resource 303 and use it. A program for using the command to be provided also can be produced as an ActiveX (ActiveX) and distributed to a recording / playback apparatus.

The storage / reproduction control unit 207 can store the broadcast content by mounting a storage area provided by the external resource 302. [ For example, the storage / reproduction control unit 207 can set a memory area or a storage area to be mounted as a shared directory through which the recording / reproducing apparatus 110 can access and read / write through CIFS (Common Internet File System). As another example, the storage / reproduction control unit 207 can set a memory area or a storage area to be mounted as a directory through which the recording / reproducing apparatus can access and read / write through the network file system (NFS).

When the capacity of the storage area provided by the local resources 301 and 302 is insufficient while the broadcast contents are stored in the storage area provided by the local resources 301 and 302, the storage / ), Switches from the storage area provided by the local resources (301, 302) to the storage area provided by the global resource (303), and continuously stores the broadcast content in the storage area provided by the global resource (303) . In general, the local resource 301 has a storage capacity of 8 GB or less with a USB memory or the like. In addition, 12 GB is generally required to store 90 minutes of broadcast content. Therefore, when the storage / reproduction control unit 207 records 90 minutes of broadcast content on the local resource 301, it may happen that the storage capacity of the local resource 301 is insufficient. At this time, the storage / reproduction control unit 207 accesses the global resource 301 based on the previously set access information and authentication information, and stores the remaining portion of the broadcast content being recorded in the storage area provided by the global resource 301, The recording / reproducing apparatus according to the present invention is capable of stably completing recording.

In addition, even when a user has the local resource 301 recorded only a part of the broadcast content and moves to another place, the user attaches the local resource 301 held in the recorded / Can be reproduced by using the contents stored in the local resource 301 and the rest can be reproduced and watched by the contents stored in the global resource 303. Therefore, even if only a part of the broadcast contents is recorded in the local resource 301, The whole can be conveniently reproduced.
