DVD Title Saving Method {Automatically DVD Title Setting Method}

The present invention relates to a method of automatically storing a title of a DVD on an HDD.

Background Art A video recording / reproducing apparatus capable of recording a broadcast signal on a recording medium or reproducing a recorded broadcast signal has been expanded in accordance with advances in digitalization and compression technology of broadcast signals. These video recording / playback devices are being developed to support the use of various video sources, such as satellite broadcast signals, cable broadcasts, and network broadcasts over the Internet. It has reached the stage of storing data on the optical media medium or playing back the stored data. Such an optical media medium has almost no deterioration in image quality due to usage period, and is rapidly replacing conventional analog image recording media because it can store high quality images and multi-channel audio data (eg, 5.1 channels). As such, an optical media medium such as a DVD title that stores image data and audio data can generally store data of several hundred Mbytes to several Gbytes. By employing a hard disk drive, which is a device, many functions are used to easily store or read a large amount of data. The video recording / reproducing apparatus has a function of reproducing A / V signals and is configured to perform independent functions. A typical example of a DVD / HDD video recording / playback apparatus is a combination of a DVD ROM for playing data recorded on a disk and a hard disk drive for recording and playing data (hereinafter referred to as "HDD") in one case. It is composed. At this time, the DVD ROM and the HDD each have an interface capable of transmitting and receiving data while performing independent functions. In general, a DVD ROM plays back respective data recorded on an optical disc recording medium such as a DVD, an audio CD, a video CD, and an MP3 CD.

The DVD / HDD video recording / reproducing apparatus may receive a broadcast signal from the outside to record data on the HDD or output the data to the HDD, or may record data reproduced from the DVD ROM to the HDD.

As described above, when recording a signal reproduced from a DVD ROM or an external signal to the HDD, a user may record a plurality of programs on the HDD using a large capacity HDD. In addition, the present invention provides a method of providing information of an I-frame that captures and displays an initial screen so that programs of a plurality of recorded video signals can be compared with each other, and a method of viewing and determining a title in a program list. have. In order to use the method of viewing and determining the program list, the title name should be recorded when recording the data. However, when recording externally input video information, if the user does not receive additional title information, the user directly selects the title. It should be recorded. That is, a sub screen for recording a title should be displayed and titles should be input for each image information using a remote controller or other input device. In addition, when recording a video signal to the HDD, an MPEG file for recording video information and a user data file for recording information about the file are created. The user data includes the file recording date, start time, end time, and file. Length, video information title, and the like. In particular, since the recording title name is programmed to display only a specific character of "PROGRAM" at the time of completion of recording or to input only "Number" which means a simple arrangement, the title name is as described above. It is inconvenient that the user must input directly.

The present invention is to solve the above problems, when copying a DVD program to the HDD to automatically pick up the title name of the DVD and to record in the user data area of the HDD so as to replace the recording title name will be.

Further, the recording step preferably records in the long-term recording area of the hard disk drive.

In the calling step, information on the DVD title name is fetched from the disc information file (F0) area of the DVD.

More preferably, the storing step includes a first storing step of storing the picked-up DVD title name in the user data area and a second storing step of storing the user data in the HDD.

The second storing step is operated to store the user data in the root directory area of the HDD.

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

1 is a block diagram schematically showing a DVD / HDD combo system having a DVD player and a hard disk drive.

The illustrated DVD player includes a switching unit 10, an MPEG encoder unit 20, a hard disk drive (HDD) 30, a flash ROM 40, a control unit 50, and a RAM ( 60, a light receiving unit 70, a digital signal processing unit 80, and an optical media player 90.

The switching unit 10 receives various image data / audio data sources from the outside or outputs the image data sources output from the decoder unit 80 to the outside (for example, a monitor screen). The switching unit 10 receives an external signal such as a component and a composite from a broadcast signal and a video (not shown), and receives the external signal from a broadcast signal and a function block in the video recording / reproducing apparatus. Connect optionally. For example, when an external signal applied from an external device such as a video is a component or a composite signal, the external signal is applied to the MPEG encoder unit 20.

The MPEG encoder unit 20 is composed of a video decoder 21, an audio ADC 22 and the MPEG encoder 23, and after analog-to-digital conversion of the analog form of the image data source applied from the switching unit 10, It is compressed in MPEG format (eg MPEG-2 format). In general, image data in MPEG format has a compressed form in order to reduce the amount of space stored when stored in a storage medium such as a hard disk drive (HDD) 30.

The hard disk drive (HDD) 30 is configured to store or read image data / audio data having an MPEG format in a data recording area in the form of a file. The physical data structure of the HDD will be described in detail with reference to FIG.

The HDD 200 includes a boot recording area 210, a FAT area 220, a data recording area 230, and a root directory area 240.

The boot recording area 210 is an area in which information on the physical structure of the HDD 200 is recorded, such as information on a drive partiton.

The FAT (File Allocation Table) area 220 is an area in which status information on which cluster of the data recording area 230 is recorded is recorded. Here, the cluster is a recording unit consisting of at least two sectors, and the large-capacity recording target data is divided and recorded in a plurality of clusters. However, even if a file is divided into several clusters, these clusters do not always have to be contiguous, and they can be scattered around the hard disk. In this case, the locations of several clusters associated with one file are managed in a file allocation table (FAT).

The data recording area 230 is an area in which data to be recorded is substantially recorded, and is divided into a long-term recording area A and an unrecorded area B. FIG.

The long-term recording area A is a nonvolatile recording area in which data to be recorded (for example, an A / V signal) is filed for a long time according to a recording command from a user. The file of data to be recorded for a long time can be edited according to the user's preference.

The unrecorded area B refers to an area in which no data is recorded, and a temporary recording area B1 is adaptively allocated for a time delay viewing function (hereinafter referred to as a "time shift function"), and is temporarily recorded. The remaining area except the area B1 remains as the empty recording area B2.

In detail, the temporary recording area B1 is a volatile recording area for temporarily recording a program currently being viewed for the time shift function, and temporarily receives a program received from the outside by a first in first out (FIFO) method. This is a recordable area.

The temporary recording area B1 is allocated to a part of the unrecorded area B so that the received program can be temporarily recorded for an "one hour" amount. When the selected buffer time is "Auto", the temporary recording area B1 is The entire recording area B is allocated to temporarily record a program received by the capacity of the unrecorded area B. If the selected buffer time is "Off", the temporary recording area B1 is received by not being allocated at all. The program is not temporarily recorded.

When the currently playing program is being temporarily recorded in the allocated temporary recording area B1, the position information of the initial cluster where the playing program is temporarily recorded, that is, the recording start position of the temporary recording area B1 is the root directory area. Is recorded at 240.

Further, when a long-term recording command is applied to a program temporarily recorded in the temporary recording area B1, the program is long-term recorded in the area in which no data is recorded in the long-term recording area A.

The root directory area 240 is an area in which attribute information, location information, and the like of long term recorded and temporarily recorded data are recorded in the data recording area 230. The attribute information of the file generated by the control unit 50 includes a file name or title name of the recording target data, a file capacity, a recorded date / time, etc., and the position information indicates the recording start address and the recording end address of the recording target data. Include. Here, the status information of the FAT area 220, the attribute information and the location information of the root directory area 240 are updated whenever an editing operation such as writing or deleting a file is performed.

The flash ROM 40 stores an operating system and an application program for operating a DVD player, and stores image data / audio data stored in the form of a file in a hard disk drive (HDD) 30. Additional information (icon, title name, recording time, file size, etc.) is displayed on the screen through a GUI (Graphic User Interface) type menu and stored in the hard disk drive (HDD) 30 through the displayed menu. An application program for editing and displaying image data / audio data is provided.

The controller 50 stores the MPEG data output from the MPEG encoder unit 20 to a hard disk drive (HDD) 30 or digitally reads the image data / audio data stored in the hard disk drive (HDD) 30. It is applied to the signal processor 80. When the DVD is played back, the control section 50 reads the information on the DVD title from the information in the disc information file area and records the information in the root directory area of the HDD 30. In addition, the controller 50 executes an application program stored in the flash ROM 40 to display icons and title names corresponding to the image data stored in the form of a file in the hard disk drive (HDD) 30 on the screen. Flash ROM 40 reads and displays the relevant GUI screen for display.

The memory (RAM) 60 loads the control unit 50 when editing the file stored in the hard disk drive (HDD) 30. That is, instead of directly editing a file stored in the hard disk drive (HDD) 30, the memory is edited in the memory (RAM) 60 and then stored again in the hard disk drive (HDD) 30.

The light receiving unit 70 is a remote control device (not shown) for controlling the video recording / playback apparatus (for example, channel switching, volume control, image quality control, etc.) or a setting key (not shown) provided in the video recording / playback apparatus. Receives a generated control signal (not shown) and applies it to the controller 50.

The digital signal processing unit 80 receives the MPEG format image data stored in the hard disk drive (HDD) 30 via the control unit 50, decodes it, and converts the image data into a video format (for example, NTSC / PAL). The converted signal can be reproduced in an image display apparatus such as a television.

The DVD player 90 reads out image data and audio data from the DVD disk and applies the same to the controller 50. Image data and audio data applied to the controller 50 are stored in the hard disk drive (HDD) 30 or applied to the digital signal processor 80 and reproduced.

The above-mentioned DVD disc has a capacity of about 4.7 Gbits and can record one movie on a single disc. In particular, the disc information file area includes information related to the disc.

FIG. 2 shows a general data structure of a DVD disc. As shown in the drawing, a DVD disc generally has a read in area A, a system area B, a volume managment area C, and so on. ), A file area (C) consisting of a plurality of files (F0 to F99), and a read out area (E). At this time, files 1 (F1) to 99 (F99) of the file area D substantially store a movie, a music video, or the like. The file 0 (F0) of the DVD disc is also called a disc information file, and contains various reference information about the data contained in the files 1 (F1) to 99 (F99) of the DVD disc. In particular, the disc information file F0 area stores the positional information of the image data corresponding to the I-frame and the DVD title information among the image data recorded in the files 1 (F1) to (99). Therefore, the disk scan can be performed using the positional information of the image data corresponding to the I-frame contained in the disk information file F0.

Such data is transmitted by the optical pickup device (not shown in the drawing) of the DVD to read the TOC (Table Of Contents) information of the DVD disc and the information of the disc information file (F0) area to the decoder unit 80 for decoding. The control part 50 which received the information of the disk information file area | region F0 stores the information of the disk information file area | region F0 in the internal memory (not shown in figure). At this time, the information in the disc information file F0 area includes information on the DVD title as described above, so that it can be read.
