2. Description of the Related Art In recent years, the digitization of information has been rapidly progressing, and the field of image information recording is no exception. Conventionally, image recording has been performed by an analog recording method, but if the image is directly digitized, it will be a huge amount of information,
A recording medium with a large memory capacity was required to record this, but due to the development of image band compression technology and the improvement of information recording density, it has become possible to compactly record images digitally. .

Therefore, recently, when image data of a television program or the like is recorded and reproduced, in order to retrieve desired image information from the information recorded on the recording medium, the image data is actually reproduced and recorded. Check the contents, or search based on the value of the counter that shows the time from the beginning of the disc,
Alternatively, a technique has been used in which a program break is marked and a search is performed based on this.

[0004]

However, it is difficult to grasp the recorded contents by such a conventional method, and when a plurality of programs are mixed in one recording medium and recorded in random time series order, It is very difficult to search and find desired image data.

A character encoder, a searcher for searching for a predetermined time and a predetermined character string, a search information input device for inputting information for searching by the searcher, and a record information display device for displaying record information. It is composed of.

[0007]

According to the present invention, with the above-mentioned structure, at least one of the time information such as the month, day, and day of the week when the image was recorded and the stored character information are coded to form a predetermined area of the information recording medium together with the image information. Time information corresponding to the image recorded on the information recording medium during reproduction,
