The present invention relates to a control method in a personal video recorder (PVR) system. In particular, the user can easily record and schedule a broadcast program anytime, anywhere using SMS of a mobile communication terminal. The present invention relates to a control method and system using SMS in a PVR system.

In general, the PVR system is broadcasted by different broadcasting stations simultaneously for up to 30 hours by applying a hard disk drive (HDD) to a TV or a set-top box (STB) as disclosed in Korean Patent Publication No. 2003-0065721 or 10-2004-0013760. It is designed to record even the most popular programs, and this system allows viewers to expand their viewing range. Recently, the PVR system is spreading in earnest, especially with the start of digital broadcasting. These PVRs have a time shift / recording function, and the recording function replaces the VCR recording. In general, the method of recording a broadcast on a PVR can be recorded directly or a scheduled recording like a general VCR. In the conventional PVR as described above, a reservation cannot be made when a user goes out to a remote place. In other words, if the user cannot directly operate the PVR, there is a problem that recording is not possible even if a desired program is not reserved in advance in the PVR. In order to solve the problem that the user cannot make a reservation in the PVR remotely, there is a reservation recording method through the Internet and a reservation recording method via a telephone. However, there is a problem in that the reservation method through the Internet must be located in an environment where a remote user can use the Internet. In addition, the reservation method through a phone can be similar to the ARS method, but in this case, the user calls until all settings are finished. Not only do you need to continue the call, but you also have the inconvenience of setting the title of the saved content as text.

Accordingly, it is an object of the present invention to provide a method and a system in which a user can easily control a PVR by using a short message service at a remote location without an internet or a telephone call.

The present invention for performing the above object is to use a short message service (SMS) at a remote location by a mobile communication terminal PVR is a process of receiving and interpreting a short message from the mobile communication terminal, and from the short message interpretation Comparing whether the user-set password matches the password set in the PVR, checking whether the password is the correct control command when the password is matched in the process, and executing the use control command when the correct command is in the process, the normal operation is performed. It consists of a process of checking the status, and transmitting the normal operation confirmation response message, and receives the SMS by the mobile communication terminal to the PVR to analyze and confirm the password and command according to the remote control. When the password for the remote control matches and corresponds to an appropriate command, the operation is executed and a response message according to the normal operation is transmitted.

DETAILED DESCRIPTION A detailed description of preferred embodiments of the present invention will now be described with reference to the accompanying drawings. First, in adding reference numerals to the elements of each drawing, it should be noted that the same reference numerals are used to refer to the same elements even though they are shown in different drawings.

1 is a PVR control system diagram using SMS of a mobile communication terminal of the present invention.

In FIG. 1, the mobile communication terminal 410 transmits an operation control signal of the PVR 600 to the telephone network 500 through the mobile communication network 300, and the exchange of the telephone network 500 transmits the PVR 600 to one subscriber. And make a call. When the normal call is formed by the call, the user receives an SMS sent to the PVR 600, and analyzes the password. When the call is confirmed to be a normal control signal, the program is controlled to record a program provided from the broadcasting station or the STB. When the normal operation is achieved, the PVR 600 generates a response signal according to the normal operation and transmits the response signal to the user mobile communication terminal 410 through the telephone network 500 and the mobile communication network 300.

2 is an internal system diagram of the PVR 600 of FIG. 1, except for the SMS transmission and reception unit 10 in FIG. 1, which is a system configuration already known or widely used in various places such as Korean Patent Application Publication No. 2003-0065721. .

When the telephone network 300 is connected through the line interface unit 1 and the mobile communication terminal 410 receives a call, it is detected by the ring detector unit 2 and inputted into the CPU 6 of the PVR 600. 6 recognizes that the call path for receiving the SMS has been formed, and enters the ready state for the entire operation of the PVR 600, the operation of the next PVR 600 according to the input command of the CPU (6) Under the control, the HDD 7 is recorded.

That is, the HDD 7 under the control of the CPU 6 stores the broadcast data and the response message to be recorded, and the HDD 7 stores the broadcast data under the control of the CPU 6, but stores other data. It can also be a VCR player, a DVD player or a CD player.

For remote control of the PVR 600 of the present invention, the SMS inputted through the line interface unit 1 is received and interpreted through the SMS transmission and reception unit 10 to confirm whether the specified password matches and is a correct control signal. If there is no abnormality, the CPU 6 sees the user's normal command and executes each operation of the corresponding PVR 600. That is, a program received from the broadcasting station or STB at the recording date and time is encoded by the MPEG encoder 9 and the HDD 7 ) And the broadcast data stored in the HDD (7) is output to the screen through the MPEG decoder (8).

In the same manner as described above, the reservation time is set and recorded in the memory unit 5 by SMS, and reservation recording is also possible under the control of the CPU 6. If the corresponding operation is normally executed, the CPU 6 generates a normal operation response signal from the HDD 7 and converts it into an SMS through the SMS transmission / reception unit 10, thereby providing the line interface unit 1, the telephone network 500, and the mobile communication network 300. ) Is transmitted to the user of the mobile communication terminal 410 in the remote place. The user recognizes the presence of an abnormal operation in the remote place of the PVR (600).

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1A through 4A to 4E.

There may be a program that the user of the mobile communication terminal 410 wants to watch through TV or satellite broadcasting at a present time or at a predetermined time while going out of the house. At this time, the user makes a call to his home through a mobile phone and sends a short message for recording or reservation recording through the mobile communication network 300 and the telephone network 500 as shown in FIG. In this case, since the PVR 600 may also be a subscriber in the telephone network 500, the CPU 6 forms a call line by a ring signal detected by the ring detector 2 through the line interface unit 1 and a short message is generated. Notifies the PVR 600 operating program that it has received. That is, the CPU 6 receives the short message in the process 301 of FIG. 3 through the SMS transmission / reception unit 10. The short message received in the section 301 is composed of a user command, channel number, recording time, title, and password fields as shown in FIG. 4A. Each field is separated by a space and the title field can be separated by quotation marks. The user may request a command such as recording reservation, recording reservation cancellation, recording start, recording stop, recording reservation list, storage content list, free storage space confirmation, and storage content deletion through a user command. 4D shows an example of a user command. When the short message received in step 301 is interpreted in step 302, first, the user's password is checked through the password field and the CPU 6 of the PVR 600 matches the password set in the memory 5. If the password does not match, the CPU 6 sends an 'error message' (FIG. 4C) as shown in FIG. 4E (FIG. 4C) in the memory 5 to the SMS transmission / reception unit 10 and the line interface unit 1 in step 315. Through the mobile communication terminal 410 of the user. However, if the password matches in step 305, the CPU 6 checks in step 307 whether the user command in the user command field is a correct command. In this case, if the user command is not a correct command, as shown in the example of FIG. 4E, an error message of 'wrong command' (FIG. 4C) is transmitted to the user. If the user command is a correct command in step 307, the operating program operated by the CPU 6 of the PVR 600 executes the user command in step 309. For example, in the case of reserved recording, counting is started while the reserved time is set, and in real time recording, the CPU 6 controls the HDD 7 to receive a program received through a broadcasting station or STB through the MPEG encoder 9. The code is recorded on the HDD 7. As described above, when the CPU 6 confirms that the user command is normally executed in the PVR 600 as described above, the response message is sent to the user's mobile communication terminal 410 in step 313 as shown in FIG. 4B. It reads from HDD (7) and sends it through SMS transmission and reception unit (10). As described above, the user may remotely issue a control command to the PVR 600 using the short message service, and the response to the control command may be confirmed through the short message service. The control method of the PVR 600 using the short message service is a useful method that can be applied to most home appliances as well as the PVR 600.

By controlling the PVR through the short message service of the mobile phone as described above, the user can simply record and schedule the broadcast program anytime, anywhere, and the control method using the short message service is not only a PVR but also other home appliances. There are also useful benefits that can be applied to products.
