The present invention relates to a method for pre-deleting a title recorded in a digital video recorder such as a DVD or DivX. More particularly, the present invention relates to a method for reproducing a title recorded while watching through a digital TV. If a reservation time is set for the recording title, the present invention relates to a method for reserving a recording title to automatically delete the recording title when the time comes.

Typically, digital TV broadcasts transmit programs compressed and multiplexed by the MPEG standard to provide clear and vivid sound. Among the MPEG standards, MPEG-2 is an international standard for transmitting video and various data for next generation television broadcasting and satellite broadcasting. MPEG-2 specifies that packets for video, sound, and other additional service information are packetized into bit streams, which include a program stream and a transport stream. In the multimedia communication using MPEG-2, the sender loads a lot of information in a transport stream and parses it into a transport stream including a lot of information at the receiver to extract and decode the information. Use it. The transport stream includes not only a broadcast program for digital TV broadcasting but also an electronic program guide (EPG), which is program guide information for each channel and time zone. Therefore, the transport stream transmitted occupies a large capacity.

However, when a user records a desired broadcast video while watching a digital TV, the user inputs a recording command by operating a remote controller or the like, so that the transport stream for the broadcast video of the channel to be recorded is a hard disk (HDD). To a storage medium such as At this time, if the capacity of broadcasting video per program recorded is more than 400 megabytes, up to 10 programs are available if the hard disk has 4 gigabytes (GB), and if the hard disk is 8 gigabytes (GB) the maximum. There is a limit of capacity that can only record more than 20 programs.

In addition, when a title is already recorded on the hard disk and its capacity is full, there is a problem that it is not easy to record immediately when there is a broadcast program to be suddenly recorded. Therefore, in order to secure an extra free space on the hard disk, the user has to check the broadcasting programs and titles stored in the hard disk one by one, and delete the material which is considered unnecessary.

In order to solve the above problems, the present invention, after playing a title recorded while watching on a digital TV, if the user has set a deletion time for the recording title to automatically delete the recording title when the time comes It is an object of the present invention to provide a method for reservation deletion of a recorded title.

According to an aspect of the present invention, there is provided a method for reserving a reserved title, comprising: a first step of reserving a title to be deleted and a deletion time from among a plurality of recorded titles; And a second step of deleting the title to be deleted when the deletion time set by counting a system time is reached.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings.

In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a configuration diagram schematically showing an internal configuration of a digital video recorder to which a method for reserving a reserved title is applied according to an embodiment of the present invention.

The digital image recorder 100 to which the present invention is applied includes a tuner 110, a demultiplexer 120, an audio buffer 130, an audio decoder 132, and a video. Buffer 140, Video Decoder 142, Data Buffer 150, Record & Play Unit 160, Controller 170 , A memory 172, a storage 180, a key input processor 190, a remote controller 192, and the like.

Here, the tuner 110 is for receiving a digital broadcast signal by tuning a specific broadcast channel according to a channel tuning command from the controller 170, and the demux 120 is a digital broadcast signal received through the tuner 110. To parse MPEG transport streams into video, audio and data signals.

In addition, the audio buffer 130 is for buffering and temporarily storing the audio signal parsed by the demux 120, and the audio decoder 132 decodes the audio signal through the audio buffer 130 to enable playback output. To restore the audio signal. In addition, the video buffer 140 is for buffering and temporarily storing the video signal parsed by the demux 120, and the video decoder 142 decodes the video signal through the video buffer 140 to enable playback output. The data buffer 150 is for buffering and temporarily storing the data signal parsed by the demux 120.

Meanwhile, the recording / reproducing unit 160 converts data input from the outside into data suitable for recording under the control of the control unit 170, and records the data on a recording medium such as a DVD, a video tape, a hard disk (HDD), or the like. A series of data recording and reproducing operations for reading and playing back data recorded on a recording medium is performed.

The controller 170 tunes the channel selected by the remote controller 192 through the tuner 110 and controls to record or display a broadcast image corresponding to the tuned channel. In addition, the controller 170 stores the deletion reservation data including the deletion time input by the user through the remote controller 192 in the storage medium, counts the system time, and automatically deletes the title of the deletion target when the deletion time is reached. To control the operation.

Here, when the deletion reservation data is stored in the storage medium, the controller 170 stores the deletion reservation data in association with the disc ID when the storage medium is a removable disk such as a CD or a DVD, and navigates when the storage medium is an optical disc. It is recorded in the area and stored in the file system in the case of a hard disk (HDD).

The memory 172 stores a channel tuned by a key input or a deletion reservation data for a title set and specified by a user, and the storage 180 records and stores various programs of digital video and audio data. For example, a DVD or a hard disk may be used.

Although not shown in FIG. 1, a network connection unit for connecting to the Internet may be provided, and a title image of a DivX file may be downloaded from the Internet and stored in a storage medium through a network connection unit connected to the Internet.

Next, an operation of the digital image recorder 100 having the above-described configuration will be described with reference to FIG. 2.

2 is a flowchart illustrating a method for reserving a reserved title of a recorded title according to an embodiment of the present invention.

First, in the digital image recorder 100, the controller 170 parses a digital broadcast signal of a broadcast channel tuned through the tuner 110 into a video, audio, and data signal of an MPEG transport stream through the demux 120. Recording is done on DVD or hard disk (HDD). In addition, when a user wants to watch a title stored in the storage 180 such as a hard disk (HDD) at a desired time, the user performs a key input related to the playback, and the controller 170 stores the storage 180 in the storage 180. The title is played back through the recording / reproducing unit 160.

On the other hand, when the user does not know whether to play or watch again in the future for the title recorded in the storage 180 and played back once, the user sets the reservation deletion function according to the present invention.

Therefore, the user performs a key input related to the reservation deletion setting through the remote controller 192 or the like to set the reservation deletion function (S202).

The controller 170 reads a list of a plurality of titles in the form of files stored in the storage 180 and outputs them on the screen as shown in FIG. (S204).

The user selects a list of titles to be deleted from the plurality of title lists because they have already been played and watched, for example, the "Sung Yi Yi 7 times" list as shown in FIG. 3 (a) by the remote controller 192 (S206).

When the title list to be deleted is selected, the controller 170 displays a screen for inputting a deletion time as shown in FIGS. 3B and 3C to inquire when to delete the title to be deleted ( S208). Here, the deletion time includes a date, a day of the week, and a corresponding time.

The user inputs reserved deletion data on a date and time desired to be deleted for the corresponding deletion target title through the remote controller 192 (S210). Here, the controller 170 provides a plurality of date tables in the form of a calendar as shown in (b) and (c) of FIG. 3 so that the user selects and inputs a deletion time, and the user can perform the deletion. If a date, " 18 days " is selected, a number of time zones can be provided to allow selection of the corresponding deletion time, for example, "20:00.

When the reservation deletion data is input through the key input processing unit 190, the controller 170 stores the reservation deletion data for the input deletion date, the day of the week, the deletion time, and the like, together with the title list of the deletion target in the memory 172. (S212). In this case, the controller 170 stores the reserved deletion data in the navigation area when the storage medium is an optical disc, and stores the reserved deletion data in the file system area when the hard disk HDD is based on an operating system (OS).

Subsequently, the controller 170 counts the system time to determine whether the deletion time set by the user is reached (S214).

When the deletion time set by the reservation is reached, the controller 170 deletes the data for the title to be deleted from the plurality of titles stored in the storage 180 based on the title list corresponding to the deletion time (S216). . Here, in the case of the removable optical disc, when the optical disc is inserted into the device, the controller 170 checks the ID of the optical disc and deletes the corresponding title on the optical disc based on the deletion reservation data of the memory 172 associated with the ID, The title is deleted based on the deletion reservation data in the navigation area of the optical disc.

Therefore, the user does not have to perform a process of checking and deleting titles stored in the storage 180 such as a hard disk (HDD).

As described above, according to the present invention, after playing a title recorded while watching on a digital TV, if the user sets a deletion time for the recording title, the recording title is automatically deleted at the corresponding time. The reservation deletion method of the recording title can be realized.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.

The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, there is no need to perform the cumbersome process of deleting a program or title stored in the hard disk in order to secure extra storage space on the hard disk. There is an effect of improving the convenience in management.
