Description of the Related Art While watching a television broadcast, sometimes it is necessary to temporarily suspend the viewing of the television broadcast due to a telephone call, a visitor, or the like. If the contents broadcast during this period are not known, in the case of news broadcasting or the like, the meaning of watching a television broadcast will be lost. In the case of a drama or a movie, the interest is lost.

For this reason, conventional television broadcast receivers include:
Some had a playback function. The conventional television recorder includes a recording device for temporarily recording a television broadcast, and a reproducing device for reproducing the contents of the television broadcast recorded on the recording device in a fast-forward or frame-by-frame manner.

[0004] When the user tries to temporarily stop watching the television broadcast, the user operates the recording switch to start recording the television broadcast, and after completing the operation, operates the playback switch to delete the recorded content. They were played back in fast-forward or frame-by-frame and connected to the current broadcast. Also,

In the above-described conventional television recorder, a memory such as a DRAM is used as the recorder. Television broadcasts include image information in addition to audio information, so even if such information is compressed and recorded, the amount of information is enormous. Therefore, a large-capacity memory is required to perform long-time recording.

However, since a memory such as a DRAM is expensive, there is a first problem that, as a practical range in terms of cost, recording can be performed for at most about 30 seconds. For example, he was planning to watch a television program starting at 19:00, but was unable to view it at 19:10, which was 10 minutes late. In addition, there is a second problem that the reproduction of the recorded contents is performed in a frame-by-frame or fast-forward manner, so that the reproduction may be difficult to see.

Further, only one program can be recorded. For this reason, for example, if a broadcast on another broadcast station is started before the reproduction catches up with the current broadcast, a third problem is that a program on the other broadcast station is missed. There was a point. Regarding the third problem,
The conventional method of broadcasting the same program with a time difference between a plurality of channels can be dealt with. However, in this conventional method,
Since a plurality of channels are used, a fourth problem occurs in that there is much waste and the broadcast cost increases.

Another object of the present invention is to provide a television recorder capable of increasing the recording capacity and reproducing at a normal speed by using an inexpensive and large-capacity recording medium for recording and reproducing by a recording head and a reproducing head, respectively. .

For example, in the above example, if the recording switch is operated, the recording is started, and after the operation is completed, that is, when the reproduction switch is operated at 19:10, the television program is delayed by 10 minutes. It is designed to be fully viewable. The time difference can be freely determined according to the manner of the recording medium. In addition to this, the invention according to claim 1 has been proposed in view of the fifth problem described above. The purpose of the invention is to provide a recording head and a reproduction head separately so that recording can be performed. Can be played at the same time. Thus, a time difference is created by sequentially playing back from a previously recorded one, so that a currently broadcast television program can be freely viewed with a time delay. (Claim 2) The invention according to claim 2 is the above-described claim 1.
In addition to the object of the invention described above, it is proposed in view of the third and fourth problems.
