The broadcast signal processing system may include a broadcast signal receiver for storing a broadcast signal in an external storage device and reproducing contents stored in the external storage device and the storage device. Various external devices, for example, the broadcast signal receiver may be connected to a variety of external devices, for example, a computer, a printer, a mobile phone. When the broadcast signal receiver receives a broadcast signal transmitted by any one of the terrestrial wave, satellite, and cable, the broadcast signal receiver may process the received broadcast signal and display the processed broadcast signal on a screen. In addition, the broadcast signal receiver may receive and process a broadcast signal through an internet network and display the same on a screen. The initiating broadcast signal receiver may apply any one that can receive a broadcast signal or reproduce the received broadcast signal.

The broadcast signal processing system may not be provided with a storage device capable of recording / storing a broadcast signal inside the receiver, but may be connected to an external storage device via wired or wireless, or may be connected to a portable storage device through a port. Hereinafter, the storage device is a storage device capable of recording and reproducing a broadcast signal and broadcast content. A buffer for data processing and a storage device for loading a program into a processor are not included in the concept of the following storage device.

Such a storage device includes an optical recording medium capable of recording or reading data using light, a magnetic recording medium capable of recording or reading data using magnetic components, and a data recording or reading data using a semiconductor chip. It may be a nonvolatile memory. Each of the above-described storage media also includes various types of media.

In addition, the storage medium may include a CF card including a nonvolatile memory, a smart card, a portable memory stick, a multimedia card, a secure digital card, and a USB memory. In addition to the simple storage medium described above, the storage device may be a display type storage medium that can provide a broadcast signal to a user, such as a PMP, PDA, mobile phone, smart phone, or the like.

Broadcast signal receivers with internal storage devices are expensive and the built-in storage devices cannot be used for other purposes. Even if a storage device is provided therein, when the storage capacity is small such that many broadcast signals cannot be stored, the broadcast signal may be stored and reproduced using an external storage device. Alternatively, even if the broadcast signal receiver has an internal storage device, an external storage device may be used together with the internal storage device.

In order to clearly describe the present invention, in the following embodiments, a storage device directly connected to the storage device through an interface such as a storage device or an input / output port for storing broadcast signals therein is referred to as a local storage device. Examples of local storage devices include internal hard disks, universal serial bus (USB) memories, USB flash memories, and the like. On the other hand, a storage device connected remotely via a network is called a remote storage device. As a remote storage device, a home server capable of storing broadcast contents, a personal computer (PC), a notebook, or the like may be used.

1 illustrates a conceptual diagram of a broadcast signal processing system in which a broadcast signal receiver includes a remote storage device. In the example of FIG. 1, the first broadcast signal receiver 100 may communicate with a storage device 300 located remotely. In FIG. 1, the first broadcast signal receiver 100 illustrates a digital television.

The network device 200 may relay the first broadcast signal receiver 100 and the remote storage device 300 to communicate with each other. The storage device 300 may provide the stored broadcast content through the second broadcast signal receiver 400 and the network device 200. In the example of FIG. 1, a notebook is illustrated as the second broadcast signal receiver 400.

The broadcast signal receiver 100 may receive and process digital content stored in an external storage device using a network even if there is no storage device therein.

When the broadcast signal receiver 100 is a mobile device or there is a change in the external storage device 300, the broadcast signal receiver 100 may be connected to the external storage device 300 through the network device 200. Meanwhile, the broadcast signal receiver 100 may be directly connected to the local storage device through an interface such as an input / output port.

That is, the broadcast signal receiver 100 may be selectively or simultaneously connected to the local storage device and the remote storage device. For example, the USB flash memory as a local storage device may be directly connected to or disconnected from a broadcast signal receiver. In addition, the remote storage device may be connected or disconnected according to the network. Hereinafter, when the broadcast signal receiver is connected to a local storage device or a remote storage device to store and play broadcast content, an expression that the local storage device or the remote storage device is mounted on the broadcast signal receiver is used.

On the other hand, the power of the local storage device can be authorized from the broadcast signal receiver, but the remote storage device has a power supply separate from the broadcast signal receiver. Therefore, the two types of storage devices may be connected to or separated from the broadcast signal receiver, as the case may be. Accordingly, the broadcast signal receiver may store and reproduce a broadcast signal in a storage device according to an exemplary embodiment. When the broadcast signal receiver is connected to the storage device to store a content in the storage device 300 or play a stored content, the video recorder mode or the digital video recorder mode may be used. It is referred to as being performed. That is, the broadcast signal receiver may store and play content in a local storage device or a remote storage device, and perform a DVR function when connected to the storage device.

2 is a flowchart illustrating a storage device connection method of a broadcast signal receiver according to an embodiment of the present invention.

The broadcast signal receiver receives a DVR mode execution command signal from the user (S0). An example of receiving a DVR mode execution command from a user will be described together in the detailed description of FIG. 6.

When the broadcast signal receiver connects to the storage device, the broadcast signal receiver attempts to connect to either the local storage device or the remote storage device to be connected (S1). An attempt to connect to a local storage device or a remote storage device may be performed according to a user's selection through a user menu of a broadcast signal receiver, or a storage device to be connected to the broadcast signal receiver may be set in advance. Hereinafter, although the storage device to be connected is assumed to be a local storage device, the following description may be similarly applied to a remote storage device. In the following description, only one local storage device and one remote storage device are considered, but the following embodiments may be similarly applied even when a broadcast signal receiver is connected to a plurality of local and remote storage devices, respectively.

In step S1, a connection to the local storage device is attempted.

If the local storage device is mounted (S2 yes), DVR mode can be performed (S3).

If the local storage device is not mounted on the broadcast signal receiver (S2 yes), the broadcast signal receiver determines whether the remote storage device is mounted (S4). For example, when the local storage device is not mounted in the broadcast signal receiver, the broadcast signal receiver may determine whether the remote storage device is mounted and provide the result to the user through a selection menu.

If there is already mounted remote storage device according to the user's selection signal (S4 yes), DVR mode can be performed using the mounted remote storage device.

If there is no remote storage device currently mounted (S4 no), a control signal for applying power to the remote storage device connected through the network is transmitted (S5). The transmitted control signal may be a signal for powering on a remotely connected device such as, for example, wake on lan (WOL). WOL (wake on lan) can power on a device, such as a remote storage device or a host that includes a remote storage device. The control signal of the broadcast signal receiver may be transmitted to a network interface unit connected to the remote storage device. Therefore, even when the power of the remote storage device is turned off, if the power of the network interface connected to the remote storage device is on, the control unit transmits a control signal such as a WOL signal to the network interface to turn on the power of the remote storage device. Can be done. Hereinafter, a method of turning on the remote storage device is similar, and an example of a control signal for turning on the power will be described in detail with reference to FIG. 7.

If the remote storage device is powered on within a certain time, and the powered on remote storage device is mounted in the broadcast signal receiver (S7 yes). The broadcast signal receiver may perform a DVR mode using a remote storage device (S3).

If the remote storage device is not mounted for a certain time (S7 no), the remote storage device is reattempted to be mounted by the setting of the broadcast signal receiver or at the user's choice (S19). If not connected to the DVR informs the user that it can not be performed (S99). If the remote storage device is connected after retrying according to a predetermined number of times or a user selection, the remote storage device is connected to perform a function according to the DVR mode (S3).

3 is a flowchart illustrating another embodiment of a storage device connection method of a broadcast signal receiver. A method of connecting a storage device of a broadcast signal receiver will be described with reference to FIG. 3.

The broadcast signal receiver receives a DVR mode execution command signal from the user (S100). An example of receiving a DVR mode execution command from a user is illustrated in FIG. 6.

After the local storage device is connected to the broadcast signal receiver (S101), a user may receive a signal related to a storage device change (S102). The broadcast signal receiver may display a menu for changing a storage device to a user to perform a DVR mode and receive a menu related to storage device selection from the user.

If the user wants to change to the remote storage device (S102 yes), check whether there is a currently mounted remote storage device (S103). If there is a remote storage device currently mounted (S103 yes), the DVR mode function may be performed using the mounted remote storage device (S104).

If the remote storage device is not mounted (S103 no), a control signal for applying power of the remote storage device currently connected to the network is output (S105). As shown in the example of FIG. 2, a WOL signal may be transmitted. Accordingly, the broadcast signal receiver may turn on a device such as a remote storage device or a server including a remote storage device.

If the power of the remote storage device is not applied even though the control signal is transmitted (S106 no), the user may be notified of information indicating that the remote storage device is not available through the menu screen (S198). In this case, the user may take actions such as using a local storage device, searching for another available storage device, or not using a DVR mode using the storage device.

If the remote storage device is powered on (S106 yes), an attempt is made to mount the remote storage device (S107). If the remote storage device is mounted on the broadcast signal receiver (S107 yes). The broadcast signal receiver may perform a DVR mode using a remote storage device (S104).

If the remote storage device is not mounted for a predetermined time (S105 no), the user is informed that the DVR mode cannot be performed using the remote storage device (S199).

4 is a flowchart illustrating still another embodiment of a method for connecting a storage device to a broadcast signal receiver. The broadcast signal receiver may not have a local storage device or may not be directly connected to the local storage device. Accordingly, the broadcast signal receiver may perform a DVR mode using a remote storage device according to the following example. Hereinafter, it is assumed that all of the remote storage apparatuses to which power is applied are mounted in the broadcast signal receiver.

Even when the broadcast signal receiver does not have a local storage device, the broadcast signal receiver may receive a DVR mode execution command signal from the user (S201).

If the broadcast signal receiver does not have a local storage device, it is determined whether there is a mounted remote storage device and the information is provided to the user (S202).

If there is a mounted remote storage device (S202 yes), and the user selects one remote storage device from the mounted remote storage devices (S203 yes), a DVR function is performed (S250). If there is no remote storage device mounted (S202 no), the user is notified that the DVR mode cannot be performed and the DVR mode is not performed (S299).

Although not currently mounted to the user, list information about a remote storage device connected through a network may be displayed (S204).

If receiving a signal for selecting a remote storage device to be connected to the user from the user transmits a control signal to turn on the selected remote storage device (S205).

If power is not applied to the remote storage device even though a control signal is transmitted to the remote storage device (S206 no), the user is notified that there is no remote storage device to be selected and the DVR mode is not performed (S299).

When the remote storage device is powered on according to the control signal transmitted in step S205 (S206 yes), the remote storage device is attempted to be mounted on the broadcast signal receiver (S207). If the remote storage device is powered on (S207 yes), the DVR mode is executed (S250). If the remote storage device is not mounted (S207 no), the DVR is notified. Do not perform (S299).

Hereinafter, an embodiment in which a broadcast signal processing system operates a connectable storage device will be described. The broadcast signal receiver may perform a DVR mode by connecting a local storage device and a remote storage device as shown in FIGS. 2 to 4. Therefore, even if the broadcast signal receiver does not have a storage device, the broadcast content may be stored and the broadcast content stored in the storage device may be read and reproduced from the storage device according to the embodiments of FIGS. 2 to 4.

Meanwhile, when both a local storage device and a remote storage device are connected, the broadcast signal receiver may play back and store broadcast content according to capacity.

The broadcast signal receiver may store the received broadcast content in both the connected local storage device and the remote storage device, or play back the content stored in the local storage device and the remote storage device.

The broadcast signal receiver may check the remaining storage capacity of the mounted storage device. If the remaining storage capacity of the local storage device is less than the reference value, the broadcast signal receiver may notify the user of insufficient capacity of the storage device in such a manner that the screen of the broadcast signal receiver expresses the fact in real time.

For example, if a broadcast signal receiver is storing content on a mounted local storage device and there is not enough space left on the local storage device, the user will display this to the user and save all or previously stored content on the mounted remote storage device. You can save the rest of the. In this case, the control signal is received from the user through the user menu, and whether or not to store it in another storage device may be selected by the control signal according to the user's selection. In this case, if the remote storage device is not mounted, the remote storage device may be powered on and mounted according to the embodiment of FIG. 3.

As another example, when the broadcast signal receiver is storing content in the mounted first remote storage device and the remaining capacity of the first remote storage device is insufficient, all of the content stored in the mounted local storage device or the second remote storage device is completely stored. Or you can save the remaining part. In this case, the broadcast signal receiver may store content stored in the first remote storage device as a local storage device when the local storage device is mounted according to the embodiment of FIG. 2. In addition, according to the embodiment of FIG. 3, the broadcast signal receiver may turn on the power of the second remote storage device that is not mounted and store the content stored in the first remote storage device in the second remote storage device.

5 is a block diagram illustrating an embodiment of a broadcast signal processing system including a broadcast signal receiver. An embodiment of a broadcast signal processing system according to the present invention will be described with reference to FIG. 5. The broadcast signal processing system of FIG. 5 may include a broadcast signal receiver 100 and a remote storage device 300. And a network device 200 that connects the broadcast signal receiver 100 and the remote storage device 300.

The broadcast signal receiver 100 includes a receiver 101, a demodulator 102, a decoder 103, a display 104, a first controller 105, a second controller 106, a graphics processor 107, The interface unit 108 may include a local storage device 109 and a control signal communication unit 110. The interface unit 108 may communicate with the wired / wireless network device 200 and may be connected to the remote storage device 300 through the network device 200. The control signal communication unit 110 may receive a signal from the user according to a user control device, for example, a remote controller 112, and output the received signal to the controller. A user menu for connecting a storage device through the remote controller 112 is illustrated with reference to FIG. 6.

In FIG. 5, for convenience of description, an example in which the first control unit 105 and the second control unit 106 are separately provided in the control unit (indicated by a dotted line) is described, but may be implemented as one system chip. In addition, at least one of the first control unit 105 and the second control unit 106 of the control unit may perform a function illustrated in hardware, firmware, middleware, software, or a combination thereof.

In addition, although the example of FIG. 5 discloses an example in which the local storage device 109 is directly connected to the interface unit 108 including an input / output port, the local storage device may be a storage device mounted inside the broadcast signal receiver 100. have.

The receiver 101 may be a tuner that receives a broadcast signal of a specific frequency through at least one of the terrestrial wave, satellite, cable, and the Internet. The receiver 101 may be provided for each broadcast source, for example, terrestrial wave, cable, satellite, or personal broadcast, or may be an integrated tuner. In addition, when the receiver 101 is a terrestrial broadcast tuner, at least one digital tuner and an analog tuner may be provided, respectively, or may be a digital / analog tuner.

In addition, the receiver 101 may receive an IP (internet protocol) stream transmitted through wired or wireless communication. When receiving the IP stream, the receiving unit 101 may process a transmission / reception packet according to an IP protocol for setting source and destination information on the received IP packet and the packet transmitted by the receiver. The receiver 101 may output a video / audio / data stream included in an IP packet received according to the IP protocol, and generate and output a transport stream to be transmitted to the network as an IP packet according to the IP protocol. . The receiver 101 is a component that receives an externally input video signal. For example, the receiver 101 may receive a video / audio signal input of an IEEE 1394 format or a stream such as HDMI from an external source.

The demodulator 102 demodulates the input broadcast signal in the inverse of the modulation scheme. The demodulator 102 demodulates a broadcast signal and outputs a broadcast stream. When the receiver 101 receives a stream format signal, for example, when receiving the IP stream, the IP stream bypasses the demodulator 102 and is output to the decoder 103.

The decoding unit 103 includes an audio decoder and a video decoder, and after decoding the broadcast stream output from the demodulator 102 or the stream reproduced through the second control unit 106 with each decoding algorithm, the display unit 104. ) In this case, a demultiplexer (not shown) may be further included between the demodulator 102 and the decoder 103 to separate each stream according to a corresponding identifier. The demultiplexer may divide a broadcast signal into an audio element stream (ES) and a video element stream (ES) and output the broadcast signal to each decoder of the decoding unit 103. In addition, when a plurality of programs are multiplexed on one channel, only a broadcast signal of a program selected by a user may be selected and divided into a video element stream and an audio element stream. If the demodulated broadcast signal includes a data stream or a system information stream, it is also separated from the demultiplexer and delivered to the corresponding decoding block (not shown).

The graphic processor 107 may process a graphic to be displayed so that the display unit 104 may display a menu screen on the video image displayed by the display unit 104 and control the graphic to be displayed together with the display unit 104.

The interface unit 108 may interface with the remote storage device 300 through a wired or wireless network. Examples of the interface unit 108 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. The interface unit 108 may output a control signal for turning on power to the remote storage device. For example, the interface unit 108 may transmit a WOL signal to a network interface unit to which the remote storage device 200 communicates to turn on the power of the remote storage device.

The second control unit 106 reproduces the content stored in the storage device 300 by the broadcast signal receiver 100 through the interface 108 or transmits the broadcast signal processed by the broadcast signal receiver 100 to the storage device 300. Can be controlled to save.

In addition, the second controller 106 may read content stored in the external storage device 300 and output the read content to the decoding unit 103 according to a user's request for playback. Content stored in the storage device 300 may be in the form of a compression-encoded stream. In this case, the decoding unit 103 decodes the compressed and encoded stream by each decoding algorithm and outputs the decoded stream to the display unit 104.

The second control unit 106 may encrypt and output broadcast content input to the receiving unit 101 and output to the storage device 300. The second controller 106 can read the encrypted broadcast signal from the storage device 300 and decrypt the broadcast signal.

The first controller 105 may control operations of the illustrated components (receiver, demodulator, decoder, display, graphics processor, second controller, interface), and the like. Then, the menu for receiving the user's control command can be displayed, and the user can be driven with an application for displaying various information or menus of the broadcast signal processing system.

For example, when the local storage device 109 or the remote storage device 200 is mounted, the first control unit 105 may include the local storage device 109 and the remote storage device 200. You can read content stored in the mounted storage device. When the local storage device 109 or the remote storage device 200 is mounted, the first control unit 105 stores the broadcast content received by the storage device control unit 106 from the reception unit 101 in the local storage device 109. And store in a mounted storage device of the remote storage device 200.

Also, as illustrated in FIGS. 2 to 4, the first controller 105 can determine whether the local storage device 109 and the remote storage device 300 are mounted according to whether the local storage device 109 and the remote storage device 300 are mounted. The first control unit 105 may control the interface unit 108 to output the WOL signal to the network interface unit (not shown) of the remote storage device 300. Can be. Therefore, even if the power of the remote storage device 300 is turned off, the broadcast signal receiver 100 turns on the power of the remote storage device 300 to store broadcast content in the remote storage device 300 or the remote storage device 300. The broadcast content stored in can be played.

In addition, the first controller 105 checks the remaining storage capacity of the local storage device 109 and the remote storage device 300, and displays the information on the user through the display 104 or the graphic processor 107. It can be displayed on the part 104. In addition, when the remaining storage capacity is insufficient in the local storage device 109, the first controller 105 may transfer the content stored in the local storage device 109 to the remote storage device 300 and store the same. In this case, when the remaining storage capacity of the local storage device 100 is insufficient, the first controller 105 stores the data locally on another local storage device (not shown) or a remote storage device 300 through the display unit 104. A menu indicating whether to transfer and store the content stored in the device 100 may be displayed. And it can receive and process the user's control signal for it. And even if the remaining storage capacity of the remote storage device 300 is insufficient, the first control unit 105 can display the content stored in the remote storage device 300 in the second remote storage device (not shown) or the local storage device 109. You can move it to and save it. Accordingly, the first control unit 105 may move and store contents stored in the local storage device 109 and the remote storage device 300 and other directly or remotely mounted storage devices.

If the first controller 105 is to move content from the local storage device 100 or the second remote storage device (not shown) to the remote storage device 300, the remote storage device 300 is powered off. 2 to 4, the remote storage device 300 may be turned on.

The display unit 104 may display broadcast content received from the receiver 101, content stored in the local storage device 109, or the remote storage device 300. According to a control command of the first controller 105, a menu for displaying information related to whether the storage device is mounted and the remaining capacity according to the embodiments of FIGS. 2 to 4 may be displayed and operated under user control. .

Hereinafter, when the broadcast signal receiver 100 is connected to the local storage device 109 and the remote storage device 300 to store a content in the storage device 300 or perform a function of playing the stored content, the video record is performed. A video recorder mode or a digital video recorder mode is referred to as being performed. That is, even when the local storage device 109 is not mounted, the broadcast signal receiver 100 may be connected to the remote storage device 300 to perform a DVR function. Alternatively, even if the remaining storage capacity of the local storage device 109 is not enough, the content may be moved to the remote storage device 300 to perform a DVR mode. An example of mounting to the local storage device 109 and the remote storage device 300 may be performed according to the embodiment of FIGS. 2 to 4.

When the DVR mode is performed in the broadcast signal receiver 100, content may be stored or played using the mounted storage devices 109 and 300 as described above. When the DVR mode is performed, the broadcast signal receiver 100 may perform functions of various playback devices using the mounted storage devices 109 and 300. For example, the broadcast signal receiver 100 may perform a function such as play, fast forward, backward, and slow play on content stored in the remote storage device 300. In addition, the broadcast signal receiver 100 may store content according to various functions. For example, there is a function called time shift. This function stores the content for a temporary time by the broadcast signal receiver 100 in the remote storage device 300, and then reproduces the stored content. Since the contents stored in the remote storage device 300 are temporarily stored, the contents stored in the remote storage device 300 may be transmitted from the remote storage device 300 to the broadcast signal receiver 100 and reproduced when they are reproduced, and deleted from the remote storage device 300. Therefore, the broadcast signal receiver 100 may play the content at a predetermined time interval with respect to the time when the remote storage device 300 receives the received broadcast content using the time shift function.

When the broadcast signal receiver 100 immediately records broadcast content to the remote storage device 300, the broadcast content may be stored in the semi-permanent storage area in the remote storage device 300. The illustrated DVR mode may operate similarly for local storage 109.

6 illustrates a menu screen for providing information to a user when a broadcast signal receiver performs a video recorder function using a mounted storage device. The broadcast signal receiver may perform a DVR mode using the mounted storage device.

FIG. 6 illustrates a menu screen displayed when a broadcast signal receiver receives a DVR mode execution command from a user when connection of a storage device is possible. The user instructs the broadcast signal receiver to perform the DVR mode on the menu screen using a user control device such as a remote controller (S0 in FIG. 2, S100 in FIG. 3, and S201 in FIG. 4). Then, the broadcast signal receiver may perform DVR mode according to the flowcharts illustrated in FIGS. 2 to 4, that is, when the local / remote storage device is mounted as illustrated in the flowcharts of FIGS. 2 to 4. The same activatable menu can be presented to the user.

That is, the graphic processor of the broadcast signal receiver may display a menu for inquiring the user about whether to perform the DVR mode according to the screen illustrated in FIG. 6. If the user wants to perform the DVR mode as shown in FIG. 6, the user may select a yes key and perform a DVR function of storing content in a storage device or playing back stored content.

If the user selects the no key, the broadcast signal receiver terminates the connection with the mounted storage device, maintains only the communication connection with the storage device until the user performs DVR mode again, and reads a content file from the storage device, Do not save.

Alternatively, when the broadcast signal processing system can perform the DVR mode, the broadcast signal receiver may store the received broadcast content using a connected storage device, or read and store the content stored in the storage device to reproduce and output the content in the broadcast signal receiver.

7 illustrates a conceptual diagram of transmitting a control signal for controlling power application to a remote storage device. FIG. 7 is a diagram conceptually illustrating the drawing of FIG. 5. FIG. 7 includes a first control unit 105 and an interface unit 108 of the broadcast signal receiver 100, a network interface unit 301 and a storage unit 303 of a remote storage device. The remote storage device may further include a control unit (referred to as a remote storage device control unit in FIG. 7) 305 for controlling the remote storage device in the case of a home server or a computer.

When the remote storage device is powered off, that is, even when power is not applied to the storage unit 303 and the remote storage device controller 305, the network interface unit 301 is powered on by a separate power source. There may be a case. In order for the broadcast signal receiver to mount the remote storage device to perform the DVR mode, the first control unit 105 of the broadcast signal receiver outputs a signal to the interface unit 108 to apply power to the remote storage device.

The interface unit 108 outputs a control signal for applying power to the storage unit 303 of the remote storage device and the remote storage device controller 305 managing the device according to the signal output from the first controller 105. do. For example, the interface unit 108 may generate and output a signal called a magic packet. This signal is generated by appending the network MAC address of the remote storage device of 6 bytes to the 6 bytes of FF FF FF FF FF FF. That is, when the remote storage device is a host such as a home server or a PC, the interface unit 108 outputs a WOL signal including an Ethernet address of the remote host and 6 bytes of FF FF FF FF FF FF to the remote host. When the network interface unit 301 of the remote host receives the WOL signal, the network interface unit 301 turns on the power to the remote storage controller 305, and the power may be applied to the storage unit 303 controlled by the remote storage controller 305. have. Accordingly, the broadcast signal receiver may store or play content by using a remote storage device in addition to the local storage device, and apply power to the remote storage device even when the local storage device or the second remote storage device lacks the remaining storage capacity. Mode can be performed.

In addition, the broadcast signal receiver may access the remote storage device in a short time to perform the DVR mode. When the DVR mode is executed, the menu for the DVR mode may be activated or generated. The broadcast content may be stored in the remote storage device or the stored content may be displayed through a menu for the activated DVR mode.

Therefore, even a broadcast signal receiver without a storage function can conveniently store and reproduce broadcast signals, and can use a remote storage device.
