2. Description of the Related Art With the spread of video decks and the development of various types of video software, video tapes on which various video software are recorded are sold in large quantities and lent in large quantities by video rental companies. On the other hand, as the development of cable television and the development of satellite broadcasting are progressing, the expansion of television broadcasting channels is dramatically increasing. Such a situation has a significant effect on television commercials.

[0003] That is, television broadcasting is generally realized, with limited exceptions, by providing a program at the expense of a company which is the main entity of television commercials.

[0004] By the way, when the rental of video tapes becomes widespread, the time previously spent watching television broadcasts can be replaced by the time spent watching video software.
For companies that are program providers, the number of viewers of their TV commercials decreases, and their advertising effectiveness decreases.

[0005] In addition, the expansion of television broadcast channels inevitably and greatly lowers the audience rating of each program. Is greatly reduced, and the advertising effect is greatly reduced.

Accordingly, as a proposal for compensating for a decrease in the audience rating of television commercials due to the spread of rental of information recording media such as video tapes and the dramatic expansion of television broadcast channels, Japanese Utility Model Laid-Open No. 3-70474 has been proposed. There is a technique as described in Japanese Unexamined Patent Application Publication No. H11-163,873.

That is, according to this technique, a user performs desired recording in a free area of an information recording medium in which additional information as advertisement information is recorded in advance, and at the time of reproduction, the user continuously records the pre-recorded additional information. The information is reproduced.

[0008]

However, according to such a conventional method, the additional information (advertisement information) area and the user recording area are independent at the beginning, so that the additional information (advertisement information) is excluded during reproduction. Playback is easy, and the advertising effect is reduced. Also, because the advertising information is generally short and only played at the beginning,
There is a problem that the memory effect when used for an advertisement or the like is weak.

Accordingly, the present invention provides an additional information recording / reproducing apparatus and information recording medium which solves the above problem by adding various kinds of advertisement information to a desired recording area in accordance with the intention of the additional information (advertisement information). The purpose is to provide.

Before describing an embodiment of the present invention, a schematic operation of the disc player 10 shown in FIG. 7 will be described.

Generally, a DVD-format digital video disc includes video data encoded in the MPEG2 format and audio data or linear PCM encoded in the MPEG format or Dolby (registered trademark) digital format.
In addition to the audio data, sub-picture data for displaying subtitles and navigation data for controlling the playback order of the player are recorded. In the video data sector and the audio data sector, each data is interleaved and recorded at a ratio corresponding to the size of the entire data.

In FIG. 7, an analog video signal for recording and an external microphone input signal, for example, are respectively A / A signals.
The digital video signal and the external microphone input signal are converted into digital signals by the D converters 1V and 1A, and are then MPEG-encoded and compressed by the MPEG encoders 2V and 2A, respectively. Next, each stream of the compressed video data and external microphone input data is formatted into a DVD format (not shown) by a DVD DSP (Digital Signal Processor) 4 under the control of a microcomputer 3.

In this format, for example, one block is composed of 16 sectors, and video data and audio data are independently arranged in each block. Audio data is recorded in units of one block, and video data is recorded in units of a plurality of blocks. That is, no video data is arranged in the audio data block. Then, the audio data stream and the video data stream in such a format are modulated by the RF LSI 5 under the control of the microcomputer 3, converted into a formatted data stream, and recorded on the DVD video disk 6.

At the time of reproduction, information recorded on the DVD video disk 6 is read and demodulated by the RF / LSI 5, and then deformatted by the DVD / DSP 4. Next, an AV (audio / video) decoder 7
To restore video data and audio data, the video data is converted to an analog video signal by the video encoder 8, and the audio data is converted to D / A.
The external microphone input converted into an analog audio signal by the converter 9 is output as Lch and Rch.

Now, on the premise that the operation of the disc player 10 is described, an embodiment of the present invention will be described in detail. In the following description of the present embodiment,
