When the private range management unit 25 receives the private range registration and release command from the command input and analysis unit 24, the private range management unit 25 registers and releases the private range terminal according to the received command.

In addition, when the private range management unit 25 receives a private range registration and release request from the device devices (terminals) through the network input / output unit 30, the device devices (terminals) register with the private range. And determining whether the device has been released, and registering and releasing the corresponding device devices (terminals) in the private use range, or notifying the corresponding device devices (terminals) of the registration and release impossible message.

In addition, when the private use range management unit 25 requests a determination as to whether or not the device device (terminal) is registered in the private use range from the reservation recording management unit 26 and the copy processing unit 27, the corresponding device device (terminal) is stored in private. It determines whether it is registered in the use range, and transmits the private use range registration information of the device device (terminal) to the reservation recording management unit 26 and the copy processing unit 27.

Here, the private use range means a copying range for private use that can be copied and distributed in the home and a similar range without the purpose of personal profit for the received broadcast program.

If the reserved recording management unit 26 receives the broadcast program reserved recording command from the command input and analysis unit 24 and the received command is a command to record a broadcast program in the broadcast program receiving apparatus 20, the corresponding broadcast program is The broadcast program protection signal recognizing unit 28 transmits a command (hereinafter, referred to as a 'first recording command') to record the broadcast program at the broadcast time.

In addition, if the received command is a command to record a broadcast program to an external device device (terminal), the reservation recording management unit 26 determines whether to register the private range of the corresponding device device (terminal). Command to record the broadcast program by the broadcast program protection signal recognizing unit 28 when the corresponding device device (terminal) is registered in the private use range (hereinafter referred to as 'second recording command'). If the device device (terminal) is not registered in the private coverage, the program protection signal recognition unit 28 informs that the device device (terminal) is not registered in the private coverage. Scope not registered information).

When the copy processing unit 27 receives the broadcast program copy request command from the command input and analysis unit 24, the copy processing unit 27 requests the broadcast program storage unit 29 to confirm whether the copy target broadcast program is stored (recorded), and broadcasts the broadcast. If the copy target broadcast program is not stored (recorded) in the program storage unit 29, a copy impossible message is output through the network input / output unit 30 (or the display unit 23), and the broadcast program storage unit 29 If the copy target broadcast program is stored (recorded), the private coverage manager 25 requests a determination as to whether to register the private coverage of the device device (copy target terminal) to which the broadcast program is to be copied.

Here, if the device apparatus (copy target terminal) to which the broadcast program is to be copied is registered in the private use range, the copy processing unit 27 transmits the copy target broadcast program to the broadcast device protection signal recognition unit 28 as the corresponding device device (copy). If a device device (copy target terminal) for copying a broadcast program is not registered in the private coverage, the broadcast protection signal recognition unit 28 sends a command (copy command) to copy to the target terminal).

3 is a diagram illustrating an embodiment of a private coverage registration and release process according to the present invention, and illustrates the operation of the private coverage manager 25 of FIG. 2.

In FIG. 3, it is assumed that the maximum private coverage is 20 (301), and that 10 device devices (terminals) are registered in the private coverage (302).

In this case, the maximum private use range may be changed by a user's command.

Here, the registration resist field 303 indicates whether to register. For example, if 0 is displayed in the registration resist field 303, it is not registered. If it is 1, it is registered.

In this case, the registration resist field 303 may be registered (for example, indicated by 1) or released (for example, indicated by 0) by a command input through the command input and analysis unit 24 of FIG. 2. .

The terminal ID field 304 indicates whether registration is possible. For example, if information is not registered in the terminal ID field 304 (that is, displayed as 0), the device ID (304) can be registered in the terminal ID field 304, and the terminal ID field 304 If the terminal ID is displayed in the terminal ID field 304, the device apparatus (terminal) cannot be registered.

In this case, the terminal ID field 304 may be registered or released by a private range registration and release request input through the network input / output unit 30 of FIG. 2.

The management information field 305 represents information of the device apparatus (terminal). For example, if PC01 is displayed in the management information, it indicates a first PC (Personal Computer) within the private use range, if PC02 is displayed, it represents a second PC within the private use range, and if PMP01 is displayed, it is within the private use range. 1 Indicates PMP (Portable Multimedia Player).

On the other hand, when a private range registration command is input through the command input and analysis unit 24, the private range management unit 25 registers the private range according to the command. For example, when a private range registration command for 10 device devices (terminals) is input through the command input and analysis unit 24, the private range management unit 25 fills 10 fields of the registration register field 303. By displaying 1, private application ranges for 10 device apparatuses (terminals) are registered.

When the private range release command is input through the command input and analysis unit 24, the private range management unit 25 releases the private range according to the corresponding command. For example, when a private range release command for five device devices (terminals) is input through the command input and analysis unit 24, the private range management unit 25 opens five spaces among the registered registration fields 303. By displaying 0, the private coverage for the five device devices (terminals) is released.

On the other hand, if a private coverage registration is requested from a device device (terminal), the private coverage management unit 25 registers the registration device field 303 and the terminal ID field 304 to register the device device (terminal) in the private coverage. ).

In this case, when the registration (for example, indicated by 1 in the registration resist field 303) is displayed in the registration resist field 303 and the information is not registered in the corresponding terminal ID field 304 (for example, the terminal). When the ID field 304 is displayed as 0), the private use range management unit 25 registers the ID of the device device (terminal) in the terminal ID field 304 to privately use the device device (terminal). Register to the scope.

On the other hand, all of the registered resist fields 303 are not registered (for example, all of the registered resist fields 303 are marked as 0), or all registered resist fields 303 (for example, registered registries) for which the private coverage is registered. All terminal ID fields 304 corresponding to field 303 indicated as 1 are already registered (eg, other terminal IDs are displayed in the terminal ID field 304) (ie, all terminal IDs). When another device device (terminal) is already registered in the field 304, the private use area management unit 25 determines that the device device (terminal) cannot be registered in the private use range and transmits an unregisterable message to the network I / O. It transfers to the said device apparatus (terminal) through the part 30.

On the other hand, if a private coverage is requested from a device device (terminal) registered in the private coverage, the private coverage manager 25 deletes the ID of the device device (terminal) from the terminal ID field 304 ( For example, the ID of the device device (terminal) registered in the terminal ID field 304 is displayed as 0).

4 shows an example of device devices (terminals) registered in the private coverage according to the present invention.

Here, the range in which the broadcast program can be copied, distributed, and accessed, that is, the private use range, may be a home (ie, home) 401.

The broadcast receiving apparatus 402 for receiving a broadcast program in the home 401 includes a set top box (STB), a sling box, a personal video recorder (PVR), and a digital television (DTV). Television) and the like, and can output a broadcast program received through the display device 403 in real time.

Through the broadcast program receiving device 402, device devices (terminals) within a private use range may be registered and released, and a private use range may be set through a user input (command).

As shown in FIG. 4, device devices (terminals) capable of copying, distributing, and accessing a broadcast program received by the broadcast receiving apparatus 402 in the home 401 include a PMP and a personal digital assistant (PDA). Assistants), portable devices 404 such as laptops, and the like, personal devices 405 that can be used in homes 401 such as PCs, and remotely accessible playback devices 406 registered in private applications such as sling boxes. ), Etc.

On the other hand, since the portal site 407 or the like connected to the external network is outside the private coverage, it is not possible to copy, distribute, and access the broadcast program received through the broadcast program receiving device 402.

5 is a flowchart illustrating a broadcast recording method for process use of a broadcast program according to the present invention.

First, when the broadcast receiving device receives the reserved recording command (501), the received command is analyzed to determine whether to record the broadcast program in the broadcast receiving device or to the external device device (terminal). (502).

At this time, if the determination result 502, a command to record a broadcast program in the broadcast program receiving apparatus, the broadcast program receiving apparatus records (stores) the broadcast program (503).

On the other hand, if the determination result 502, a command not to record a broadcast program in the broadcast program receiving apparatus (that is, a command to record a broadcast program to the external device device (terminal)), the broadcast program receiving apparatus records the broadcast program and It is checked whether the device device (recording target terminal) to be registered is registered in the private coverage (504).

For example, the broadcast program receiving apparatus may check whether a device device (a recording target terminal) for recording a broadcast program is registered in a private coverage range with reference to the table as shown in FIG. 3.

As a result of the check 504, if a device device (recording target terminal) for recording a broadcast program is registered in the private use range, the broadcast program receiving apparatus delivers the broadcast program to the corresponding device device (recording target terminal), and The device device (terminal) enables the recording (storage) of the broadcast program (505).

On the other hand, if the check result 504, the device device (recording target terminal) to record the broadcast program is not registered in the private coverage range, the broadcast program receiving apparatus checks whether the protection signal of the broadcast program exists (506) ).

As a result of the check 506, if the protection signal of the broadcast program does not exist, the broadcast program receiving device transmits the broadcast program to the corresponding device device (recording target terminal), so that the device device (terminal) records the broadcast program ( Store) (505).

On the other hand, if there is a protection signal of the broadcast program as a result of the check 506, the broadcast program receiving apparatus transmits a record impossible message indicating that the broadcast program cannot be recorded to the device device (or display unit) (507).

Thereafter, the broadcast program receiving apparatus displays the recording result through the display unit (or the corresponding device apparatus) (508). That is, when the broadcast program is successfully recorded (refer to steps 503 and 505), the broadcast receiving device displays recording completion information. If the broadcast program is not recorded (see step 507), the recording is not completed. Display the information.

6 is a flowchart illustrating a broadcast program copying method for process use of a broadcast program according to the present invention.

First, when the broadcast program receiving apparatus receives the broadcast program copy request command (601), it is analyzed whether the copy request broadcast program is recorded (stored) by itself by analyzing the received command (602).

As a result of the check 602, if the broadcast program requested to be copied is not recorded (stored), the broadcast program receiving apparatus cannot copy the broadcast program to the device device (or display unit) to which the broadcast program is to be copied. Forward the message (603).

On the other hand, if the check result 602, the broadcast request broadcast program is recorded (stored), the broadcast program receiving apparatus checks whether the device device (copy target terminal) to copy the broadcast program is registered in the private coverage (604).

For example, the broadcast program receiving apparatus may check whether a device device (copy target terminal) to which a broadcast program is to be copied is registered in a private range by referring to a table as shown in FIG. 3.

As a result of the check 604, if the device device (copy target terminal) to which the program is to be copied is registered in the private use range, the broadcast program receiving apparatus is directed to the device device (copy target terminal) to which the program is to be copied. The broadcast program is delivered to allow the device apparatus (copy target terminal) to copy the broadcast program (605).

Here, the broadcast program receiving apparatus includes a broadcast signal (for example, copy permission count = 0) indicating that further copy is prohibited in the broadcast program and transmits it to the corresponding device device (copy target terminal).

On the other hand, if the confirmation result 604, the device device (copy target terminal) to copy the broadcast program is not registered in the private coverage range, the broadcast program receiving apparatus checks whether the protection signal of the broadcast program exists (606) ).

As a result of the check 606, if the protection signal of the broadcast program does not exist, the broadcast program receiving device transmits the broadcast program to the corresponding device device (copy target terminal), so that the device device (terminal) can copy the broadcast program. (605).

On the other hand, if the check result 606, the protection signal of the broadcast program exists, the broadcast program receiving apparatus transmits a copy impossible message indicating that the broadcast program cannot be copied to the corresponding device device (or display unit) (603).

Thereafter, the broadcast reception device displays the copy result via the display unit (or the corresponding device device) (607). That is, the broadcast reception device displays copy completion information if the broadcast program has been successfully copied (see step 605), and displays copy incomplete information if the broadcast program has not been copied (see step 603). .
