Description

The present invention relates to a video information processing apparatus and a video information processing method, and more particularly, to a suspension process and a restart process during video playback.

In recent years, DVD (Digital Versatile Disk) recorders or HDDs (Hard Diss) have been used as devices for recording and reproducing video and audio processed in video devices such as televisions.
k Drive) Digital video information processing devices such as recorders have become widespread.
One of the functions of these digital video information processing apparatuses is a resume function.

The resume function is, for example, a video information processing apparatus such as an optical disc recording / reproducing apparatus.
This is a function for automatically starting playback from the previous playback stop point at the next playback after playback stop. Specifically, when the optical disc recording / playback apparatus receives a playback stop instruction from the user, the playback stop position on the optical disc is detected, and a pointer indicating the detected playback stop position is recorded as the next playback start point. By using this function, when a playback start instruction is received again after playback is stopped, it is possible to perform continuous playback from the position where playback was previously stopped by referring to the stored next playback start point. Is possible.

In relation to the resume function described above, Patent Document 1 discloses an optical disk playback device in which the resume function is enhanced by recording various information at the time of playback stop in the HDD. The optical disk playback apparatus disclosed in Patent Document 1 resumes a resume point that is a playback stop position, playback stop date and time information, and still image information at the time of playback stop for each optical disk that has been played back every time video playback is stopped. Are recorded in the HDD.

When the user performs reproduction using the resume function, a list of still images and reproduction stop dates and times of a predetermined number of resume points on the corresponding optical disk are displayed based on the resume information recorded in the HDD. When the user selects any resume point based on the still image of the resume point and the playback stop date and time, the playback of the video is started from the selected resume point. When a plurality of playback stops are performed on the same optical disc, the plurality of playback stop positions are used as resume points. For this reason, video reproduction can be started from any one of the plurality of resume points.

According to the above-described invention of Patent Document 1, a list of still images and playback stop dates / times of a predetermined number of resume points is displayed, so that the target resume point can be easily determined by referring to the still images and playback stop dates / times. You can find and select. Furthermore, since resume information is recorded for each optical disc, the same resume function can be used for any optical disc. Further, even when the optical disk is replaced once, the resume function can be used for the optical disk before replacement.

However, in the conventional video information processing apparatus represented by the optical disk recording / playback apparatus of Patent Document 1, a video information list (for example, a recorded program list) is provided even if there is a function for displaying a list of resume points to the user. Etc.) did not have a function to display the presence / absence of a resume point. For example, as shown in FIG. 6, in the recorded title list screen of the conventional video information processing apparatus, there are only “reproduced” and “unreproduced” as parameters indicating the reproduction state, and there are parameters indicating the resume state. There wasn't. Therefore, even if the program has already been played, it has not been possible to distinguish whether the program has been viewed to the end or whether playback has been paused (resume state).

Therefore, in order to check which recorded title is in the resumed state, the user has to perform operations such as playing recorded programs one by one or confirming detailed information of recorded programs on another screen. . In addition, for example, when a user tries to delete a recorded program that is in a resumed state, a warning message or the like is not displayed, so there is a possibility that a recorded program that is being viewed may be deleted. .

For this reason, the maintainability of data (recorded content) can be enhanced.

An embodiment of the present invention will be described below with reference to the drawings.
[Embodiment]
<1. About internal structure of HDD recorder>
Here, the main configuration of the electric circuit system of the HDD recorder 1 according to the first embodiment of the present invention will be described with reference to the block diagram of FIG.

As shown in the block diagram of FIG. 3, the HDD recorder 1 of the present invention includes at least a control unit 1.
1, memory 12, HDD 13, data input unit 14, encoder unit 15, decoder unit 16,
Data output unit 17, program storage unit 18, operation button group 21, and front panel 2
2 is included.

The control unit 11 is a central processing unit for performing overall control of video information processing (content recording or playback, etc.) by organically controlling the drive of each member of the HDD recorder 1.
The control unit 11 is a central part that controls each device (for example, the HDD 13), calculates data, processes, and the like.

The memory 12 is a medium for temporarily storing various data held by the HDD recorder 1 and is configured by, for example, a writable RAM (Random Access Memory). Memory 1
2 has a role as a buffer memory for temporarily storing processing data when various kinds of information processing are performed by the control unit 11, instruction commands received from a user, and the like.

The HDD 13 is a magnetic storage medium for recording various data (video data, audio data, management data, etc.) held by the HDD recorder 1. The HDD 13 is physically divided into a plurality of areas (partitions), and it is more desirable to store the areas according to the type of data to be stored (video data, management data, etc.).

The data input unit 14 receives digital data (for example, from an external device such as a digital tuner).
This is an input interface for inputting (video information). For example, when analog data is input, analog video data and audio data can be converted into digital data and input using an A / D converter (Analog Digital Converter).

The encoder unit 15 is a processing circuit for compressing (encoding) video data using a moving image compression method such as MPEG2, and compressing audio data using a sound compression method such as Dolby AC-3 or LPCM. Note that the data to be compressed is, for example, video data and audio data input from the data input unit 14.

The decoder unit 16 is a processing circuit for decompressing (decoding) the video data and the audio data compressed by the encoder unit 15 and the like. The decompressed data is output to an external device using, for example, a data output unit 17 described later.

The data output unit 17 is an output interface for outputting video data and audio data to an external device such as a monitor. For example, if the output device has only an analog interface, a D / A converter (Digital Analog Converter)
) Can be used to convert digital video data and audio data into analog data for output.

The program storage unit 18 is a medium for storing program data for performing various types of processing (for example, video data input / output control, etc.) using the control unit 11, for example, a ROM (for example, a ROM that can only read information). Read Only Memory) is used.

The operation button group 21 is an input interface for the user to give various instructions to the HDD recorder 1 such as program recording and playback. The front panel 22 is a user interface for displaying various information of the HDD recorder 1 to the user.
<2. Resume status display process>
Here, the resume state display step in the recorded content of the HDD recorder 1 of the present invention will be described with reference to the flowchart of FIG. 1, the block diagram of FIG. 3, and the table of FIG.

As shown in FIG. 1, this process is started when the control unit 11 detects an instruction to display a list screen of recorded contents from the user (S10). The recording content list screen display instruction is issued, for example, when the user performs a recording information display operation using the operation button group 21.

Receiving the instruction to display the recorded content list, the control unit 11 acquires the playback history of the recorded content recorded in the HDD 13 (S20), and resumes recording (recorded before) from the acquired history to the recorded content. And a record indicating that the reproduction has been interrupted) (S30).

As a result of the determination processing in S30, when the control unit 11 determines that the recorded content is in the resume state, a display indicating that the content is in the resume state is performed on the output device (for example, a monitor) (for example, FIG. 4). ("Program C" shown in FIG. 4)), the process proceeds to S60 described later (S35). As a result of the determination process of S30, when it is determined that there is no resume recording in the recorded content, the control unit 11 again records the recorded content that has been reproduced from the history acquired in S20 (the previous reproduction has been performed). (S40) is determined (S40).
).

As a result of the determination processing in S40, when the control unit 11 determines that the state of the recorded content is the reproduced state, a display indicating that the content has been reproduced is performed on the output device (for example, a monitor) (for example, ("Program A" shown in FIG. 4), the process proceeds to S60 described later (S
45). As a result of the determination processing in S40, when it is determined that there is no recorded recording in the recorded content, a display indicating that the content is in an unplayed state is performed on the output device (for example, a monitor) (for example, as shown in FIG. 4). “Program B”), the process proceeds to S60 described later (S50).

The control unit 11 confirms whether or not the status display of all the recorded contents has been performed (S60), and if there is a recorded content that has not been displayed, the process proceeds to S20 described above, and the status display process of the remaining recorded contents is performed. . If the status of all recorded content has already been displayed, this process ends.

Through the above processing, for example, a recorded content list screen as shown in FIG. 4 is created and displayed on an output device (such as a monitor). In the present embodiment, the rightmost column of the recorded content list is a column representing the playback state. Program A is “reproduced”, program B is “unreproduced”, and program C is “resume”.

In the above embodiment, only the playback state of the recorded content list is displayed. For example, as shown in FIG. 5, a parameter indicating the degree to which the recorded content has been played is displayed on the list display screen. May be. In the example of FIG. 5, the playback rate of program A that is “played” is 100%, the playback rate of program B that is “not played” is 0%, and the playback rate of program C that is “resume” is 40%. It is shown that.

Note that it is not always necessary to play 100% of the content in order to be in the “played” state. If the content is played over a certain percentage (for example, 80%), the “resume state” is displayed even if the playback is interrupted. The processing may be performed so that it is determined that “replayed” instead of “”.

Also, in this embodiment, when a recorded content list display command is received from the user, the recorded content list is created by performing the status confirmation processing of each content, but before receiving the instruction from the user A list of recorded contents may be created in advance and stored in the memory 2 or the HDD 3 (for example, immediately after the recording process or the reproduction interruption process is performed).

In this embodiment, the status of the recorded content is “resume status”, “played”,
Although only three “unreproduced” are illustrated, the present invention provides the same effect even if there is a state of the recorded content other than this.

Further, in the present embodiment, the processing in the recorded content list display screen has been described. However, in a list display screen other than the recorded content list screen (for example, an edit target content list screen displayed when editing content) Needless to say, even if the resume state is displayed in the same manner as described above, the same effect can be obtained.
<3. Processing steps when deleting content on the recorded content list screen>
Here, the processing steps when content deletion is instructed on the recorded content list screen in the HDD recorder 1 of the present invention will be described with reference to the flowchart of FIG. 2, the block diagram of FIG. 3, and the table of FIG. To do.

As shown in FIG. 2, this process is started when the control unit 11 detects the deletion of the recorded content from the user (S100). The instruction to delete the recorded content is issued, for example, when the user performs an operation to delete the recorded content using the operation button group 21.

Upon receiving the instruction to delete the recorded content, the control unit 11 acquires a playback history of the recorded content to be deleted from the recorded content recorded in the HDD 13 (S110), and resumes the recorded content from the acquired history. It is determined whether there is a record indicating a state (a state in which playback has been performed before and playback has been interrupted) (S120).

As a result of the determination processing in S120, when the control unit 11 determines that the state of the recorded content is the resume state, for example, a message indicating that the content is in the resume state is displayed on an output device (for example, a monitor). Etc., a warning is given to the user (S130). Note that the continuation processing (deletion processing, etc.) when it is determined that the resume state is not in effect is the same as that in the prior art, and thus description thereof is omitted here.

In the above embodiment, the recorded content deletion process has been described with an example. However, in addition to the deletion process, a process for changing the content of the recorded content (for example, an editing process for extracting and combining a part of video) ), It is more preferable to display a warning message to the user by the same processing method as described above.
<4. Various features of the present invention>
According to this embodiment,
When a screen displaying a list of recorded contents recorded in the HDD 13 of the HDD recorder 1 confirms the playback history of each recorded content, confirms whether there is a recorded content in a resumed state, and there is a corresponding content In the list screen display process,
Display resume status.

As a result, the user can confirm at a glance which recorded content is in the resumed state. As in the prior art, there is a feature that convenience for the user is improved because it is possible to save the trouble of playing back each content and confirming detailed information of each content.

According to this embodiment,
When a process for changing the contents (deletion or editing, etc.) of the recorded content in the resume state is instructed, a warning message or the like is displayed using an external device or the like to notify the user.

As a result, for example, it is possible to prevent erroneous operations such as the user erasing past recorded content (resume content) that has not been viewed, and to improve data integrity.
