TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus and a method for processing recorded data of a television broadcast program.
[0002]
[Prior art]
A video data recording / reproducing apparatus using a large-capacity random-access optical disk as a storage medium instead of a conventional VTR is provided for home use, and an environment is being prepared in which even a general user can continuously perform a large amount of recording. is there. In addition, convenient ways of connecting these new devices to a home network and cooperating with each other have been introduced. In an environment in which a large amount of video can be arbitrarily recorded without being aware of the recording time, even if recording is performed simply, if the recorded content is played back later, a large amount of recorded video Finding the image you want to watch from inside requires a great deal of effort.
[0003]
Conventionally, in order to reserve a television broadcast program, for example, a recording reservation operation is performed with a remote control while watching an operation screen displayed on a television screen. As a recording reservation operation instruction by the remote controller, input operations such as start and end of a recording time, a day of the week, and a channel number are performed. At the time of this recording reservation, the file name for managing the data to be recorded has been input by the user every time the file name is easy to identify. Although this function of recording reservation is convenient, it is necessary to input such items one by one, so that it is troublesome and difficult for the user to use. The situation is easy to get the impression that.
[0004]
On the other hand, if the user does not enter a file name, a file name of a character string having almost no meaning is automatically assigned, and the recorded data is stored in the file. As a result, since it is extremely difficult to search for a file name that is automatically given and has little meaning, searching for desired recording data from a large amount of recording data requires a great effort. Therefore, from the general user, there is a device with a mechanism that allows the user to easily find the recorded broadcast program that the user wants to re-watch with a simple operation from a large amount of recorded data with a simple operation. It is strongly desired.
[0005]
[Problems to be solved by the invention]
Conventional TV broadcast program recording data processing devices, when recording a TV broadcast program by specifying the time, day of the week, channel number, etc., the file name of the recorded data, unless the user inputs each time, arbitrary The file name will be assigned automatically. Therefore, when a large amount of recording is performed, it is necessary for the user to search for desired recording data. Further, since the recorded data is not organized, it is difficult to distinguish between necessary data and unnecessary data in the recorded data, and there is a problem that the storage medium cannot be used efficiently.
[0006]
The present invention has been made in view of the above-described problems of the conventional technology, and has as its object to assign an easily identifiable file name to recorded data having substantially the same contents, and So that they can be easily searched. In addition, they can be stored in the same folder in the order in which they were stored, making it easy to organize recorded data, making it easy to determine whether or not recorded data is necessary, and enabling efficient use of large-capacity storage media. It is an object of the present invention to provide a recorded data processing device and a recorded data processing method.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a recorded data processing device of the present invention includes:
Recorded data previously stored in a recorded file with a specific file name,
Recording data comparison means for comparing the newly recorded recording data with recording data stored in a recording file with a specific file name in the past,
When almost the same recorded data is detected by the recorded data comparing means, the header of the file name for managing the newly recorded data is set to the same as the previously recorded file having the specific file name, and the file name is changed. File / folder management means for automatically assigning files / folders.
[0008]
Further, the recorded data processing method of the present invention compares recorded data obtained by newly recording with previously recorded data stored in a recorded file having a specific file name, and substantially similar recorded data is detected. When a file is recorded, the header part of the file name that manages the newly recorded recording data is the same as the recorded file with a specific file name in the past, and the file name with date or version information is automatically assigned. It was made.
[0009]
Further, it is effective that the recording data comparison means is configured to compare and record only recording data within a predetermined time after starting a new recording or within a predetermined range within the recording time. It is.
[0010]
Further, the file / folder management means may add a specific file name in the past to a header part of a file name for managing newly recorded recording data when substantially the same recording data is detected by the recording data comparing means. It is preferable that a file name to which date or version information is added afterward be automatically assigned in the same manner as a recorded file.
[0011]
Further, it is preferable that the storage location of the file of the newly recorded video data is arranged and managed in the same folder as the previously recorded video file having the specific file name in the order of storage.
[0012]
Further, the file / folder management means may be configured to specify a file name and a file storage location of the recorded data based on electronic program guide (EPG) data in the case of recorded data of a terrestrial digital broadcast program. it can.
[0013]
In addition, the same recorded portion in a plurality of associated recorded files can be used as an icon of a folder that stores the associated plurality of files.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described based on examples with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a recording data processing device according to the present invention. This embodiment will be described assuming both a recording data processing device that supports EPG (Electronic Program Guide) and a recording data processing device that does not support EPG in the case of terrestrial digital broadcasting. In the case of a recording data processing device that supports EPG, it is possible to accurately specify a file name and a file storage location for managing recording data on a broadcast program basis using the EPG data. Conversely, in the case of a recording data processing device that does not support EPG, the manufacturing cost can be reduced.
[0015]
In the EPG, for example, a list of broadcast programs is displayed in a matrix in which two parameters of channel and time are used as parameters, a horizontal axis is a channel, and a vertical axis is time. The EPG includes information such as a channel number, a program name, a broadcast start time, and an end time. That is, by referring to the EPG, it is possible to know which program is being broadcast on which channel and in which time zone, and it is possible to cope with a sudden program schedule change. Therefore, the use of the EPG data is extremely convenient for setting the recording program reservation and storing and organizing the recording data.
[0016]
As shown in FIG. 1, the recording data processing apparatus includes a receiving unit 1, a recording unit 2, a control unit 3, a display part 4, a recording reservation table 5, a recording data processing unit 6, a recording data comparing unit 7, a file / folder. A management unit 8, an operation unit 9, and a menu operation unit 10 are provided.
[0017]
In the case of a recording data processing device supporting EPG, the receiving unit 1 receives video, audio, and EPG data. In the case of a recording data processing apparatus that does not support EPG, the receiving unit 1 receives only video and audio. The recording unit 2 includes, for example, a large-capacity storage medium such as an HDD or a DVD, and stores encoded video and audio data. The control unit 3 controls the entire recording data processing device. The display unit 4 displays the composited data, that is, the video and the EPG received by the receiving unit 1. The operation unit 9 receives an instruction from a user such as a channel name, recording, reproduction, or a file name for managing recorded data. The menu operation unit 10 reflects an instruction (selection of a cursor or the like) from the operation unit 9 on various menu screens displayed on the display unit 4. That is, the instruction input from the operation unit 9 is received in correspondence with the instruction from the operation unit 9 and the various menu screens displayed on the display unit 4.
[0018]
In FIG. 1, when an instruction to view a broadcast program is issued from the operation unit 9, the instruction to view is output to the recording unit 2 via the viewing / recording reservation table 5. The recording unit 2 outputs a television signal to the display unit 4 via the control unit 3 in response to the viewing instruction. Thus, a desired channel image is displayed on the display unit 4 in response to the viewing instruction.
[0019]
In FIG. 1, for example, when an instruction to reproduce predetermined content having a clear file name is issued through the operation unit 9, the control unit 3 is managed by the file / folder management unit 8 in response to the instruction. A search is made for a recording file having a specific file name corresponding to the target content, and the recording data (video and audio) stored in the recording file is read out, decoded, and the target content is displayed on the display unit 4. Is displayed.
[0020]
Further, when the target channel is selected and the recording is instructed via the operation unit 9, the control unit 3 records the encoded video and audio data corresponding to the target channel in response to the instruction. Record in Part 2. Thereby, a target broadcast program can be recorded. With this series of recording operations, a file name such as a program name and date is automatically assigned with reference to the EPG data in the case of a recording data processing device that supports EPG. If there is recording data of a similar broadcast program in the past, the storage location of the file is also stored in the same folder in the storage order.
[0021]
On the other hand, in the case of a recording data processing device that does not support the EPG, as shown in FIG. 2, the recording data comparison unit 7 compares newly recorded recording data with recording data already recorded and stored. As a method of comparing recorded data, it is possible to compare all recorded contents and confirm the similarity of the recorded contents, but since this method takes time, a certain amount of time is required after a new recording is started. By setting only the comparison within the time (for example, 5 seconds or more and 30 seconds or less), the time required for the processing is considerably reduced. The reason why the comparison is made only within a certain period of time after the start of the recording is to take advantage of the fact that fixed opening image data is often included at the beginning of the content.
[0022]
As a result of the comparison by the recorded data comparison unit 7, for example, substantially the same image as (B) part of the recorded data in FIG. 2 and (D) part of the image in the newly recorded data When the data is confirmed, (C) as shown in the newly recorded / saved file, the file name header portion is made the same, and thereafter a file name with date or version information is automatically assigned. . The storage location of the file is also stored in the same folder in the storage order, as shown by the folder (E). As described above, there is a recorded file having a specific file name in the past, and the similarity of the image content between the recorded data stored in the specific file and the newly recorded data is recognized. In this case, the same file name as the file name of the recorded data already recorded and stored is automatically assigned and managed.
[0023]
As shown by the (F) icon in FIG. 2, by using the same image portion in the file associated as described above and using it as an icon of a folder in which those files are stored, Further, it becomes possible for the user to intuitively and easily identify the contents of the image data.
[0024]
【The invention's effect】
Since the present invention is configured as described above, the file name of the recorded data can be intuitively determined, and the user can easily search for the desired recorded data. In addition, related recording data is automatically assigned the same file name in the header of the file, and is automatically stored in the same folder in the order in which it is stored, so that recording data can be organized without bothering the user. Is performed. This makes it easy to determine the necessity / unnecessity of the recorded data, and enables efficient use of a large-capacity storage medium.
