Description

Method for editing record program in PVR {Method for editing record program in PVR}

The present invention relates to a method for editing a program recorded in a mass storage device, and more particularly, to a method for editing a program recorded in a storage medium of a device such as a personal video recorder (PVR).

In general, VCR (Video Cassette Recorder) using tape media has been mainstream as a device for recording analog broadcast signals. In recent years, however, a number of recording media have emerged in the era of digital broadcasting, which has advantages over analog broadcasting. Examples thereof include a digital VCR, a hard disc drive (HDD), a recording device using an optical disc, and the like. In particular, due to the recent rapid development of technology, HDD has increased to about tens of gigabytes (Giga bytes) whose recording capacity is comparable to that of tape media.

In addition, as the digital broadcasting starts in earnest and the spread of digital TV receivers spreads, DTV receivers having various additional functions have emerged in response to various user demands.

In addition, the PVR (Personal Video Recorder) function, which is one of the attention-added DTV add-ons, provides various playback functions using the above-described large capacity HDD. In other words, unlike the conventional analog VCR tape, the PVR digitally stores audio and video information, thereby guaranteeing an image quality without loss of information even when recording and playing indefinitely.

The functions of the PVR include functions similar to those of a conventional VCR, such as normal play, fast forward, slow forward, and fast reverse play of a broadcast program stored or buffered. ), Slow rewind, and the like.

In addition, another function of the PVR is a time shift function that allows a user to simultaneously store and play a broadcast program being watched. For example, if you receive a call while watching a current program, press the button for time shift (for example, pause button) on the remote controller to save the broadcast stream received thereafter. If the play button is pressed again after the phone call, the scene from the paused screen stored in the HDD can be viewed. In other words, storage and playback are simultaneously performed at regular time intervals.

The PVR function includes scheduled recording and instant recording. Unlike the conventional VCR method, the scheduled recording or instant recording function uses the built-in mass storage hard disk (HDD) of the device, so there is no inconvenience in inserting and removing a VCR tape. Rather than searching through it, random-access is possible.

FIG. 1 is an example of a general block diagram of a digital TV receiver having such a PVR function. The tuner 101 selects a high frequency (RF) signal of a specific channel from a signal transmitted from a broadcasting station and selects an intermediate frequency (IF) signal. After the conversion to the output to the demodulator 102, the demodulator 102 performs demodulation and digital processing for the IF signal of a particular channel and outputs it in the form of a transport stream (TS). The transport stream TS is output to the buffer 106 for display and to the PID filter 103 for storage in a storage medium 105 such as an HDD.

The TS stored in the buffer 106 is output to the A / V decoder 107. The A / V decoder 107 separates the audio and video streams from the transport stream in which the audio and video streams are multiplexed. The decoder performs decoding to output the speaker and the TV screen.

In addition, when recording a broadcast signal to the storage medium 105, the storage stream 105 is directly stored in the storage medium 105 through the PID filter 103 and the time stamp module 104 without decoding the transport stream. Subsequently, when the broadcast signal recorded in the storage medium 105 is reproduced, the transport stream stored in the storage medium 105 is transferred by the A / V decoder 107 through the time stamp module 104 and the buffer 106. The audio and video are decoded and output to the speaker and the TV screen, respectively.

The PID filter 103 filters the packet having the video PID and the audio PID corresponding to the program to be stored among the demodulated TPs using the PID information in the header area of the transport packet TP to the time stamp module 104. Output

The time stamp module 104 inserts a time stamp representing the time received in the filtered video and audio transport packet and records it in the storage medium 105. In addition, during playback, the time stamp module 104 transmits the playback TP to the A / V decoder 107 via the buffer 106 while maintaining the correct bit rate with reference to the time stamp of the TP played back from the storage medium 105. do. This is to prevent a decoding error due to overflow or underflow of the decoder buffer. At this time, the time stamp is removed from the playback TP and sent to the buffer 106. In other words, the time stamp is referred to only during playback.

Here, the time stamp is added to the TP to be recorded on the storage medium 105 so as to make the reproduction speed at the time of future reproduction the same as at the initial transmission.

At this time, when the user performs the scheduled recording or instant recording in the digital TV receiver having the PVR function as shown in FIG. For example, assuming that the recording was performed from 9:50 to 10:50, the one-hour amount of data may include advertisements, and may include portions of other programs not desired by the user. Also, the part of the recorded program that the user really wants may be part of it.

In addition, the reserved recording function may be recorded differently from the user's intention when the program is transmitted out of time specified by the broadcasting station. That is, the first part or the end part of the program may not be partially recorded.

Such recorded contents may include contents that the user does not want. Then, the user has a desire to store only the desired part of the recorded content.

In addition, the capacity of the HDD is limited, but if all the contents that the user does not want are stored in the HDD, it causes unnecessary waste of the HDD. Therefore, in order to save the recording space (that is, the disk capacity) of the HDD, the user may want to delete the remaining part while leaving only a part of the already recorded part.

These features are not available in existing PVR products.

An object of the present invention is to provide a recording program editing method in a PVR that selectively re-records only a part of the data recorded on the HDD of the PVR through editing.

Another object of the present invention is to provide a method for editing a recorded program in a PVR, which allows a user to set a plurality of editing sections while reproducing a program recorded on the HDD, and then to re-record it as one file.

According to an aspect of the present invention, there is provided a method for editing a recorded program in a PVR, by designating at least one start and end point of an edit section by using an edit key of a remote controller during playback of a program recorded on a storage medium. Setting more than one editing section, and if more than one editing section is set in this step, newly designate a starting point within the first editing section to be made into one editing section, and specify a new ending point within the last editing section. Setting the starting point to the new one editing section from the actual starting position of the newly designated editing section to the actual ending position of the newly designated editing section, setting at least one or more editing sections in the above steps, If you select the end of the currently playing program, Asking whether or not to reflect the information in the user menu, form, including the step of performing a recording operation according to the user's selection is characterized in that formed.

The method may further include selectively removing the set editing section from the editing target by using a remote controller key indicating 'excluding editing' when at least one editing section is set in the above steps.

When at least a plurality of edit sections are set in the above steps, the two adjacent edit sections are automatically reset to one edit section when the difference between the end point and the start point of the two adjacent edit sections is less than a predetermined time. Characterized in that.

In the re-recording step, when a user selects a menu item for reconfiguring individual edit sections into independent programs, each edit section is reconfigured into a program file and stored in the storage medium.

In the re-recording step, when the user selects a menu item for reconfiguring the plurality of edit sections into one program, the re-recording step may reconfigure the plurality of edit sections selected by the user into one program file and store the same in a storage medium.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

Hereinafter, with reference to the accompanying drawings illustrating the configuration and operation of the embodiment of the present invention, the configuration and operation of the present invention shown in the drawings and described by it will be described as at least one embodiment, By the technical spirit of the present invention described above and its core configuration and operation is not limited.

In the present invention, a method of reproducing data recorded on a storage medium of a PVR (hereinafter referred to as HDD) while specifying only a part of the data and selectively re-recording on the HDD only for a specified section is called an editing function. Here, the use of the term may be applied to a wider variety of applications and will not be limited to the examples given above.

In the present invention, a progress bar is displayed on a part of the bottom of the screen as shown in FIG. 2 when playing a recorded program stored in the HDD.

The progress bar indicates the location 100 currently viewed by the user among the entire recorded programs. In FIG. 2, totalDuration is the total playback time of the recorded program, and currentTime represents the time for the location currently viewed by the user. These values may be placed around the top, bottom, left, and right of the progress bar to help the user understand.

And, if the user wants to edit and store them separately on the HDD during playback of the recording program, the section is designated using a special remote control key for 'editing'. Here, the start and end of the editing section may be toggled using the same key of the remote controller, or may be assigned by using different keys.

3 shows a display state of a progress bar when a user designates two editing sections during playback of a recorded program.

The two edit sections shown in FIG. 3 record the start and end points with two values, editedStartTime and editedEndTime. Here, editedStartTime 11 represents the start time of the first edit section, and editedEndTime 12 represents the end time of the first edit section. In addition, editedStartTime 21 indicates the start time of the second edit section and editedEndTime 22 indicates the end time of the second edit section.

The start and end points may be designated by the user using the above-described remote control key during an operation such as fast forwarding, rewinding or slow playback.

In this case, the two editing sections set in FIG. 3 may be combined into one as shown in FIG. 4.

That is, when selecting the 'editing start' in the first edit section and 'editing end' in the second edit section using the remote control, etc., three edit sections are set, but the three edit sections are one due to overlapping parts. It is regarded as the editing section of.

Therefore, the three editing sections set as shown in FIG. 4 are shown to the user as one editing section as shown in FIG. 5. That is, in FIG. 5, editedStartTime 11 represents the start time of the edited periods merged into one, and editedEndTime 22 represents the end time of the edited periods merged into one.

In addition, one of the two editing sections set in FIG. 3 may be excluded from the editing target by using a remote control key indicating 'excluding editing'. Here, if the user sets two editing sections, one or two editing sections may be excluded from the editing target. This may vary depending on the number of editing sections set by the user.

As shown in FIG. 6, when the difference between the end point and the start point of two adjacent editing sections is less than a predetermined time (for example, 2 seconds), two adjacent editing sections are regarded as one editing section.

That is, in FIG. 6, since the end point of the first edit section and the start point of the second edit section are very close to each other, the two edit sections are merged into one. As a result, the edit section is automatically reset from the editedStartTime (11) point to the editedEndTime (22) point.

If the user decides to end the playback of the recorded program after designating the editing section in the above-described manner, the digital TV receiver having the PVR function uses the OSD (On Screen Display) processing to reflect the edits to the user or not. Ask in conversation.

For example, the user may be asked whether to reconfigure individual edit sections into independent program files and store them in the HDD, or to recombine and store them in one program file.

Here, the dialogue format, the OSD font, the OSD menu item, the OSD display form, etc. may be changed by the designer, and thus the present invention will not be limited to the examples described above.

7 illustrates an example of an interactive OSD menu shown to a user. In Fig. 7, when the user selects independent editing from the menu item, the individual editing sections are re-recorded on the HDD as one independent recording program file. For example, in a song program, each singer's song can be designated as an editing section, and an independent program file for each singer can be used to re-record.

In addition, when the user selects integrating editing in the menu item, at least two individual editing sections are made into one program file and re-recorded into one recorded program. For example, when the start and end time of the program specified in the scheduled recording may be different, the start and end time can be specified with sufficient time, and the merge edit function can be used to delete unnecessary advertisements at the beginning and end. have. Also, the coalescing editing function can be used when an advertisement or the like is inserted in the middle of a program and a program is deleted from the advertisement. If the user selects no editing in the menu item, the contents of the specified editing section are ignored and the original recording program is maintained. In addition, if the user selects cancel in the menu item, the user can continue to watch the recorded program and readjust the editing section without stopping the playback of the recorded program.

Here, when an independent mailbox or a merge mailbox is selected from the menu item and the user-edited editing section is re-recorded on the HDD, the existing program being played is deleted from the HDD, and only the contents of the editing section are recorded on the HDD.

As described above, according to the method of editing a recorded program in a PVR according to the present invention, the user may set at least one or more editing sections while playing a program recorded on the HDD, and then combine the plurality or more editing sections into one or more. In addition, the user-designated editing section can be easily recognized in the form of a progress bar, thereby providing the user with an easy editing function of the recorded program, as well as a part that is unnecessary to the user. Can be deleted. In addition, by specifying the option of re-recording as an independent program or re-recording of individual editing sections to a single program for a plurality of designated editing sections, not only user convenience but limited storage capacity are provided. Effective use of the capacity of the device (HDD) can be achieved.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
