2. Description of the Related Art Recently, a hard disk video recorder (hereinafter, also simply referred to as a recording / reproducing apparatus) equipped with a fixed disk drive (hereinafter, simply referred to as HDD) has come to be used. This type of recording / reproducing apparatus has the following features.

[0004] Since compressed and encoded information such as the MPEG-2 system is handled, writing and reading of the information is fast. Since an HDD (Hard Disc Drive) employs multiple heads, information can be read while writing information. Since the magnetic disk is built in the drive unit, it is not necessary to insert and remove a tape as in a video tape recorder. Since the information recording address is file-managed, the cueing of the information is quick. Since a series of information is handled as a data sequence in a packet unit, it is easy to connect information with information.

[0005] In addition, HD which does not assume media exchange
The D-video recorder is more useful as a temporary buffer than storing a number of recorded data inside the set for a long time. In the case of a videotape, we just had to overwrite the data we no longer needed without erasing it. In this regard, in the case of an HDD, since there is no beginning or end for a user like a tape, it is necessary to secure free space by deleting data for each file, instead of overwriting unnecessary data.

[0006]

According to a recording / reproducing apparatus such as a hard disk video recorder, a video tape recorder is used for recording / reproducing program information content in which advertisement information is inserted in the middle of an arbitrary broadcast program. For example, there is a request that the user wants to skip the commercial video and view only the program information.

However, in the conventional recording / reproducing apparatus, since a series of program information contents and advertisement information of a broadcast program are recorded in one file, the user must find the advertisement information while watching the program information contents. You must perform an operation that skips that part. In addition, when the advertisement information occupies a large amount of the HDD, there is a problem that a memory area for recording new program information content is reduced.

In view of the above, the present invention has been made to solve the above-mentioned conventional problems. In the case of recording and reproducing program information contents in which advertisement information is inserted in the middle of an arbitrary broadcast program, a program such as a movie is used. It is an object of the present invention to provide a recording / reproducing apparatus and a recording / reproducing method that allow information contents to be viewed seamlessly in a commercial cut state.

[0009]

According to the present invention, there is provided a recording / reproducing apparatus for recording / reproducing program information content in which advertisement information is inserted in the middle of an arbitrary broadcast program. A tuner device, a storage device having a predetermined recording capacity for recording and reproducing the program information content and the advertisement information received by the tuner device, and at least the program information content recorded in the storage device And / or a control device for controlling reading and writing of the storage device based on the operation information by the operation device, and
This control device is characterized in that at least when the program information content is selected by the operation information, the advertisement information is excluded and only the program information content is sequentially read from the storage device.

According to the recording / reproducing apparatus of the present invention, when recording / reproducing the program information content in which the advertisement information is inserted in the middle of an arbitrary broadcast program, when the arbitrary broadcast program is received by the tuner apparatus, , The program information content and the advertisement information are recorded in the storage device. When the operating means is operated so as to select the program information content and / or the advertising information recorded in the storage device, the control device controls the reading and writing of the storage device based on the operation information by the operating means. In the control device, at least when the program information content is selected, the advertisement information is excluded, and only the program information content is sequentially read from the storage device.

[0011] Therefore, since the program information content can be continuously reproduced, the program information content such as a movie can be viewed seamlessly in a commercial cut state. Also, if advertising information is selected, the program information content is excluded,
Only the advertisement information is sequentially read from the storage device. Therefore, since the advertisement information can be continuously reproduced, it is possible to verify a commercial video or the like in a state where the contents of program information such as a movie are cut.

Of course, when the program information content and the advertisement information are selected, the program information content in which the advertisement information is inserted in the middle of the broadcast program can be reproduced like a normal video tape.

A recording / reproducing method according to the present invention is a method for recording / reproducing program information content in which advertisement information is inserted in the middle of an arbitrary broadcast program. And advertising information,
Here, the separated program information contents and the advertisement information are recorded in a predetermined memory area, and the program information contents and / or the advertisement information are set to be selected at the time of reproducing the information. At least, the program information contents are selected. When set, only the program information content excluding the advertising information is sequentially read from the memory area.

According to the recording / reproducing method of the present invention, when recording / reproducing the program information content in which the advertisement information is inserted in the middle of an arbitrary broadcast program, the program information content can be continuously reproduced. And other program information can be viewed seamlessly in a commercial cut state.

When the advertisement information is selected, the contents of the program information are excluded, and only the advertisement information is sequentially read from this storage device. Therefore, since the advertisement information can be continuously reproduced, it is possible to verify a commercial video or the like in a state where the contents of program information such as a movie are cut.

The video encoder 21 performs the above-described encoding processing using a memory (not shown).

The video encoder 21 can fix or change the bit rate (information transfer rate) when generating the encoded video data. At the fixed bit rate, for example, code amounts are allocated to I, P, and B pictures, and the code amount allocated to each picture is made to match the actual generated code amount.
The quantization scale code is dynamically changed by feedback control.

On the other hand, at the variable bit rate, the operation control unit 50 controls the quantized scale code according to the visual characteristics so that the average value of the bit rate becomes a desired value. In other words, in a portion where deterioration is conspicuous visually, the quantization scale code is adjusted so as to be finely quantized, and the code amount is increased.In a portion where deterioration is not conspicuous, the code amount is adjusted by coarsely quantizing the code. Reduce. In this way, the bit rate is varied so that the average value is controlled to a desired bit rate. Therefore, with a variable bit rate, good image quality can be obtained even if the bit rate is low. In this example, 2, 4, 6 Mbit /
