Next, the recording reservation processing in the recording reservation apparatus having the above configuration will be described.

FIG. 6 is a flowchart showing a recording reservation setting process of the recording reservation device in FIG.

For example, when a desired program to be recorded is designated via the input interface 8 according to the program information displayed on the picture tube (monitor) 4, the setting information of the recording reservation is set according to the program information of the program designated for recording. The data is stored in the data memory 12 (step S1).

Then, following the setting of the recording reservation, the remaining storage time of an image storage area such as a video tape or an optical disk (not shown) and the recording time from the recording start time to the recording end time set as the recording reservation are set. Are compared (step S2), and when it is determined that the recording storage area is insufficient (step S3), the recording mode included in the recording reservation information is switched to the compression recording mode (step S4), and the longer recording mode is set. A time image storage area is secured.

Here, when the mode is switched to the compression recording mode, a message for notifying the user of the switching is displayed, and the user can select to continue or cancel the setting of the recording reservation.

Further, when the mode is switched to the compression recording mode, the remaining storage time of the image storage area is compared again with the set recording reservation time (step S).

Even when the mode is switched to the compression recording mode, if it is determined that the image storage area is insufficient (step S6), a message is displayed to inform the user of the fact, and the recording reservation is made as it is. Confirmation of whether to continue setting or cancel setting (step S7)
Is prompted.

Here, when an instruction to cancel the setting of the recording reservation is given, the setting data of the recording reservation stored in the recording reservation data memory 12 is erased, and the reservation of the recording is released (step S8).

Next, a recording reservation changing process in the recording reservation apparatus having the above configuration will be described.

FIG. 7 is a flowchart showing a process for changing the recording reservation of the recording reservation device in FIG.

When a recording reservation is set and stored in advance in the recording reservation data memory 12, the program information extraction unit 6 uses the program information extraction unit 6 to set the program of the corresponding channel immediately before the set recording start time based on the recording reservation information. Information 21 and 2
2 is extracted, and the contents of the program information for which the program change information 29 is set are compared with the recording reservation information (step S21).

When it is determined that there is a change in the program set as the recording reservation (step S22), the reservation setting contents of the recording reservation information stored in the recording reservation data memory 12 indicate that the program change information 29 The setting is changed according to the set program information 22 (step S23).

Then, with the change of the recording reservation setting, the remaining storage time of an image storage area such as a video tape or an optical disk (not shown) and the recording start time to the recording end time changed as the recording reservation are changed. The recording time is compared (step S24), and when it is determined that the recording storage area is insufficient (step S25), the recording mode included in the recording reservation information is switched to the compressed recording mode (step S26). A longer image storage area is secured.

Further, when the mode is switched to the compression recording mode, the remaining storage time of the image storage area is compared again with the set recording reservation time (step S).
27).

Even when the mode is switched to the compression recording mode, if it is determined that the image storage area is not enough (step S28), a message for notifying the user of this is displayed, and the recording reservation is made as it is. Confirmation of whether to continue setting or cancel setting (step S2
9) is prompted.

Here, when an instruction to cancel the recording reservation setting is issued, the recording reservation setting data stored in the recording reservation data memory 12 is erased, and the recording reservation is released (step S30).

Therefore, according to the recording reservation apparatus having the above configuration, the program information 21 and 22 (channel number 23, broadcast number) are stored in the empty area 42 of the vertical blanking period 41 of each channel in the broadcast signal transmitted from the broadcast station. Date 2
4, broadcast start time 27, broadcast end time 28, program change information 29, program title 30, etc.), and extract and use the program information 21 and 22 from the received broadcast signal. Since the change of the program contents can be recognized in real time, for example, when the program contents change, the setting contents of the recording reservation stored in the recording reservation data memory 12 are recognized as the change. In accordance with the program information, the change can be automatically set without the user's intervention, so that only the program desired by the user can be reliably recorded without wasting unnecessary image storage areas.

In the above-described embodiment, the recognition judgment of the program change information 29 accompanying the extraction of the program information 21 and 22 from the received broadcast signal is performed at regular time intervals and immediately before the start of the scheduled recording. However, by performing the same program change recognition processing immediately before the end of recording, it is possible to prevent interruption of recording when the broadcast time of the recorded program is suddenly extended, for example. Become like

The program information data memory 11, the recording reservation data memory 12, and the image storage area in the above embodiment are either a RAM using a semiconductor memory or a DVD (digital video disk) -RAM using an optical disk. And a ROM (CD-RO) storing the program information 21 and 22 in advance.
M etc.) and may be used in combination with the RAM.

Next, various types of information (recording / reproduction) (search / display) (reservation setting) when the program information 21, 22 and the recording reservation information and the recorded image information are recorded using a DVD-RAM. (Edit) will be described.

(Recording / Reproduction) FIG. 8 is a diagram showing an allocation state of an information recording area in a DVD-RAM.

In the DVD-RAM 51, a program and index information recording area 51a is allocated on the inner peripheral side thereof.
Also, a moving image recording area 51b is allocated on the outer peripheral side.

Program and index information recording area 51a
The program information 21 and 22 extracted via the program information extracting unit 6 in the recording reservation device are recorded, and the recording reservation information, the index information after recording, and the like are recorded in the recording information.

In the moving image recording area 51b, a moving image accompanying recording of a program according to the recording reservation information is recorded.

FIG. 9 is a diagram showing an example of the program and index information recorded in the index information recording area of the DVD-RAM.

The index information includes the program information 2 stored in the index information recording area 51a.
The “program title”, “type”, “recording date and time”, “recording start position”, “recording time” and the like are recorded for each recorded program based on the recording reservation information.

That is, in order to search for what kind of moving image is recorded in the DVD-RAM 51, as shown in FIG. 9, “program title”, “type ( Index information that records “sports, drama, etc.”, “recording date / time”, “recording start position”, “recording time”, etc. is useful.

FIG. 10 is a flowchart showing an index information recording process accompanying the recording of a broadcast program on the DVD-RAM.

That is, when recording of a broadcast program is started according to the recording reservation information stored in the program and index information recording area 51a of the DVD-RAM 51, the program and the program stored in the index information recording area 51a are started. "Program title" and "Type (sports, drama, etc.)" to be recorded based on information 21 and 22
Is read and recorded as index information (step A1).

At the same time, a moving image of a program accompanying the recording is recorded in the moving image recording area 51b (step A2).

Then, as the image is recorded in the moving image recording area 51b, the “recording date and time”, “recording start position” and “recording time” are further recorded as index information in the program and index information recording area 51a. (Step A3).

Conventionally, the index information is recorded automatically from the internal clock for the recording time and the recording date and time. However, the title, performer, and the like must be manually input in characters. It took a long time to input and was a very cumbersome task.

According to this, the distributed program information 21,
The program title, performers, synopsis, and the like can be read out based on No. 22 and recorded as recording index information without manual intervention, so that it is very efficient.

On the other hand, when reproducing and using the index information recorded on the DVD-RAM 51, for example,
When the D-RAM 51 is inserted into the recording / reproducing device, the program and the "program title" recorded in the index information recording area 51a are searched and output to an image output device such as a TV to easily record the recorded program. Can be understood. Further, a desired “program title” can be selected using input means such as a remote controller, and a recorded program can be reproduced from the “recording start position” of the corresponding index information.

Therefore, not only can a desired recorded program be easily selected and played back, but also by searching for information contents recorded as other index information, for example, whether a desired performer is recorded on this disc. , Etc., can be performed.

Further, by linking with the program information 21 and 22,
By attaching a recorded mark to the list of program information to be displayed, or by changing the color and outputting an image, it is possible to easily determine whether or not the program has been recorded.

(Search / Display) FIG. 11 shows the DVD-RA
FIG. 3 is a block diagram mainly showing a configuration related to search and display of record information for M.

The program information 21 distributed from the broadcast station,
When the DVD 22 is recorded on the DVD-RAM 51, various display formats can be selected when displaying a list of TV programs on a monitor.

The most basic display method is to display broadcast programs of all genres in a matrix by taking a broadcast channel on the horizontal axis and a broadcast time on the vertical axis, like a TV program column of a newspaper or the like. .

On the other hand, in the following, an embodiment will be described in which the user can easily find a program he / she wants to view by displaying by genre rather than displaying a list of all broadcast programs.

FIG. 12 is a diagram showing a state of displaying a list of broadcast programs by genre-based display.

That is, as shown in FIG. 12, for each genre such as movie, sports, drama, music, animation, cooking, news / weather forecast, etc., only programs of that genre are selected and the broadcast time and broadcast channel are selected. It is displayed as a matrix. By displaying a list by genre as shown in the figure, a user can easily search for a desired broadcast program from programs of a genre to be viewed.

FIG. 13 is a diagram showing a state of displaying a list of broadcast programs in a hierarchical display for each genre.

That is, hierarchical display can also be performed for display by genre, and a more detailed list display can be performed for upper, middle, and lower genres.

For example, in the case of a drama genre, FIG.
As shown in (1), it is also possible to make settings for broadcast time such as 1-hour drama and 2-hour drama as the middle genre, and for types such as trendy drama and historical drama as the lower genre.

[0097] In the case of sports, display by type such as baseball, sumo, soccer, etc. is also prepared as a lower menu. The lower menu is displayed in detail by, for example, selecting a large genre and then specifying the lower menu by the user.

These genre-based displays are performed by providing a flag specifying a genre in the program information 21 and 22 before distributing the program information 21 and 22 from the broadcast station 55, The user who receives or obtains the program guide (information 21 and 22) retrieves the information in the recording reservation device 50 as a genre-specific flag by the retrieval means 53 provided in the device, thereby displaying the program list. It is possible to select a program of only a necessary genre.

Then, only the necessary genre selected by the search means 53 is created by the creation means 54 as a matrix of the broadcast time and the broadcast channel, and is displayed on the monitor 4 in a list. Further, the above-described upper, middle, and lower genre classification can be achieved by linking to a flag indicating a higher genre and attaching a middle or lower flag.

A specific method from the search to the display is realized by, for example, a recording reservation device 50 as shown in FIG.

In the recording reservation device 50 shown in FIG. 11, detailed data of a program table (program information 21 and 22) is transmitted in an online distribution system (a radio wave is transmitted from a broadcasting station by communication, a bidirectional use of the Internet and CATV). In this case, the distribution is performed by an offline distribution method (CD-ROM, DVD-ROM, DVD-RAM).
Etc.).

For example, as shown in FIG.
The program guide data (program information 21 and 22) delivered by the broadcast signal from the TV 5 is recorded on, for example, a DVD-RAM 51 as a storage unit via a receiving unit 52 provided in the recording reservation device 50. Will be saved.

The program table data (program information 21, 22)
Contains an enormous amount of data including moving images and still images, and a storage means having a large storage capacity and a rewritable DVD-RAM 51 is desirable. Or other storage device.

The data stored in the DVD-RAM 51 is provided with a flag corresponding to the type of the program in advance as described above. The user inputs a genre to be specified using an input device 8 such as a remote controller, a keyboard, and a mouse in order to create a program list for each genre as necessary. The genre information input from the input device 4 is input to the flag search means 53, and flag search processing is started.

The flag search means 53 searches the DVD-RAM 51 for program information to which flag information corresponding to the input genre information is added, based on the input genre information, and temporarily searches the DVD-RAM 51 for necessary program information. It is stored in another storage area inside.

When all the necessary program information has been searched, the program for each genre selected according to the information read from the DVD-RAM 51 by the list creating means 54 for creating a program list. Then, it is created as a list according to genre as shown in FIG.

Further, in this embodiment, the following search can be performed in addition to the above-described search by genre.

For example, when it is desired to search by the name of a performer of a music program or drama, a keyword search of the performer is possible. In the case of a search by genre, a genre can be specified to some extent. Therefore, a flag corresponding to the genre is added to the program information 22 in advance, and based on this flag data,
Although the search can be performed by the flag search means 53, in the case of a keyword search, it is not realistic to add the flag information in advance because, for example, the number of performers to be searched becomes enormous. Therefore, a configuration is adopted in which performer names, such as artist names, group names, and actor names, included in the program information are searched from all information as a full-text search.

As data to be distributed, the following data can be included in addition to the data for displaying the program information in various formats as described above.

In particular, a menu other than the program guide display for displaying program information can be prepared so that data other than the distributed program information can be displayed or searched.

As the display data other than the program information, various kinds of information such as best 10 information can be adopted. For example,
