The present invention relates to a recording apparatus having an edit recording function and a control method thereof so as to understand and grasp.

Currently, television broadcasting is classified into general television broadcasting received through a general antenna and satellite television broadcasting received through a satellite antenna and cable television broadcasting received through a cable. There will also be a lot. Here, in the case of cable television broadcasting, dozens of channels are allocated to broadcast professional programs such as education, news, and sports for each channel.

As such various broadcast programs are broadcasted, there are many broadcasts that you want to watch, but you cannot watch them directly at the time of broadcasting. In general, you can reserve the broadcast program through a recording device and then play the recorded broadcast program to watch it later.

However, when there are many reserved recording programs, the capacity of the tape is insufficient so that all of the reserved broadcast programs cannot be recorded and some of them are not recorded.

Also, when there are many recorded recordings, it takes too much time to play all the recordings sequentially and view them, so you can quickly browse through the scenes you are interested in and skip through them without having to play them all in order. Occurs.

Meanwhile, in recent years, various data broadcasts such as subtitle broadcasts are performed together with broadcast programs, and thus, information on the broadcast program is transmitted through data broadcasts.

Data broadcasting refers to a broadcasting system that transmits various types of digitally encoded information that is not included in an audio signal or a video signal, and includes teletext, a video program system (VPS), a video programmed video recorder (VPV), and a Korean broadcasting program system (KBPS). ) Has been put to practical use.

In data broadcasting using a television signal, non-return to zero (NRZ) modulated information is multiplexed and transmitted in a vertical blanking interval (VBI) of a television.

On the other hand, by using a data broadcast such as setting a rating for the program, only viewers who have permission to view the rating can also be used for viewing purposes.

In addition, when recording a program, the contents of data broadcasting are identified to determine the exact time at which the correct program starts and the exact time at which the program ends. It can also be recorded.

However, in this way, when you play the entire program after the pre-recorded recording, you can play all the recorded content while only watching a specific scene. There is inconvenience,

Therefore, as a method for recording only a specific scene during recording as described above, a program such as sports relaying by KBPS in the registered patent publication No. 10-0211248 (published on April 30, 1999) "VSI's highlight recording processing system and processing method". Discussing the exact start position and end position to detect the output signal level of audio system and recording only when it is over a certain value It is.

However, in the case of such a method, the highlight portion in sports, such as a goal, can be recorded, but not only in the case of a general program, but also in the case of a program with a story, there is a problem in that the plot cannot be grasped.

The present invention was created to solve the above problems, and an object of the present invention is to transmit edit points and a plot of a broadcast program for caption editing when highlighting the broadcast program when transmitting a broadcast program. Extracts edit points and subtitle information from the broadcast signal received from the recording device, extracts the caption information inserted only at the edit points, and synthesizes and records them together to play the highlights of the corresponding broadcast program. The present invention provides a recording apparatus having an edit recording function and a control method thereof for understanding and understanding.

The recording apparatus having an edit recording function according to the present invention for realizing the above object comprises a recording unit which detects a broadcast signal input through a tuner and records a sound signal and a video signal processed by the audio processor and the image processor. An apparatus, comprising: a caption decoder for decoding caption information from a broadcast signal input through a tuner, a caption generator for generating subtitles according to the caption information decoded by the caption decoder, and tuned according to a reservation recording information The controller further comprises a control unit for determining the recording time according to the information input from the caption decoder among the broadcast signals, and outputting and synthesizing the caption generated by the caption generating unit to the image processing unit and controlling the recording unit according to the recording time. It is done.

In the present invention, the recording time point is characterized in that the recording start, pause, recording stop.

In addition, the caption information is characterized in that the plot and the scene description of the program.

In addition, the control method of the recording apparatus having an edit recording function according to the present invention, the step of extracting the identification code from the input broadcast signal when the edit recording mode is set, recording start, pause according to the extracted identification code And controlling recording stop, and generating captions according to caption information at the start of recording and synthesizing the video signal with the video signal.

In the present invention, the operation of the edit recording mode is characterized in that it is processed within the reservation recording time.

In the present invention, the broadcast signal may further include inserting identification symbols into edit points for editing and inserting caption information into the edit part.

When the broadcast program is transmitted, the present invention is made by inserting identifiers into edit points for editing highlights and inserting caption information into the edited portions, and extracting the identifiers from the caption decoder to record only at the edit points. Subtitles are generated and recorded through the inserted caption information, so that the main part of the broadcast program can be simply played through the highlight portion and subtitle information of the broadcast program for playback.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this embodiment is not intended to limit the scope of the present invention, but is presented by way of example only.

1 is a block diagram schematically showing a recording apparatus having an edit recording function according to the present invention.

As shown here, a general recording is made of a recording unit 40 which detects a broadcast signal input through the tuner 10 and records sound signals and video signals processed by the audio processor 20 and the image processor 30. In the apparatus, a caption decoder 50 for decoding caption information from a broadcast signal input through the tuner 10 and a caption generator 70 for generating a caption according to the caption information decoded by the caption decoder 50. And the timing of recording according to the information input from the caption decoder 50 among the broadcast signals input by tuning according to the reservation recording information, and outputting the caption generated by the caption generator 70 to the image processor 30. And a control unit 60 for synthesizing and controlling the recording unit 40 to record according to the recording time point.

At this time, the edit points for the highlight part are determined by experts who have watched the corresponding program at the broadcasting station in advance, and the caption contents describing the scene of the edited part or the plot are determined. An identification symbol for controlling is inserted and caption information is inserted into the edited portion so that the caption contents can be extracted from the edited portion.

In addition, when the controller 60 determines the recording time through the identification symbol, the recording start for the recording of the highlight portion, the pause for the pause in the non-highlight portion, and the identification for stopping the recording when the recording ends. Use the symbol to determine the recording time.

Therefore, the identification code transmitted along with the broadcast signal is separated and extracted from the caption decoder 50, and then the recording unit 40 is controlled to record only the edited point where the highlight is edited, and then input and synthesize the recorded subtitle with the video signal for editing. The video alone makes it possible to understand the entire plot and scene of the program.

Specifically, this will be described with reference to a flowchart for describing a control method of a recording apparatus having an edit recording function according to the present invention shown in FIG. 2.

First, the editing points for the highlight portion are determined by experts who have previously watched the corresponding program at the broadcasting station in the broadcast signal, and the caption contents describing the scene of the edited portion or the story line are determined. The process of inserting the identification symbol for controlling and inserting the caption information into the caption contents should be preceded.

In addition, the present invention is a case of the reservation recording is made within the entire reservation recording start time and the reservation recording end time that the broadcast program is broadcasted (S12) (S26) (S34).

Therefore, it is determined whether the reservation recording has started (S12). When the reservation recording time is reached and the reservation recording is made, the reservation recording mode is determined to determine whether the recording mode is the edit recording mode (S14).

In this general recording mode, the entire broadcast program received from the scheduled recording start time to the scheduled recording end time is recorded (S32) (S34).

However, in the edit recording mode, the identifiers inserted into the edit points for editing are extracted from the input broadcast signal (S16).

Thus, in the case of recording start, caption information is extracted to generate captions, and video recording is synthesized together with the generated captions to start recording (S18).

When the pause signal is input while the recording is started as described above, the recording is paused (S28) (S30).

At this time, the broadcast program continues, but the recording is not performed, so that the part not highlighted and edited is not recorded.

As the above operation is repeated, recording is performed in the highlight edited section and paused in the non-highlighted edited section so that the recording is not recorded. When the broadcast program is edited and recorded, the stop signal for stopping recording is input. If so, the recording is stopped (S28) (S36).

In addition, recording is stopped even when the scheduled recording time ends (S26) (S34) (S36).

The edited recording is highlighted and edited so that the entire program's plot and important scenes can be watched with subtitles in a short time.

As described above, when the broadcast program is transmitted, the edit points and subtitles in the broadcast signal received from the recording apparatus are transmitted when the broadcast program receives the edit points for editing the highlight of the broadcast program and the plot of the broadcast program. By extracting the information and extracting the caption information inserted only in the edit points, and synthesizing and recording with the video, only the highlights of the corresponding broadcast program are reproduced, so that the entire program can be understood and grasped in a short time.

In addition, the present invention has the advantage of reducing the waste of the tape for recording the unnecessary part by recording only the highlight portion is recorded by the entire program.

In addition, the present invention can reduce the amount of tape by recording only the highlight portion, there is an advantage that the burden on the remaining amount of the tape can be reduced even when pre-recorded many broadcast programs.
