Abstract

A digital information recording apparatus includes a recording circuit for recording information of a retention period included in the digital information and indicating a period for permitting the digital information to be held in the recording medium, starting with a time at which the digital information is recorded on the recording medium; and information of a playback permission period included in the digital information and indicating a period for permitting the digital information to be played back starting with a time at which the information is reproduced initially following recording of the digital information on the recording medium, permitting temporary recording or copying for the information permitted for “copy never” or “copy one generation.”

Claims

1. A recording and reproducing apparatus, comprising:

a receiver which receives audio/video information and a control information related to the audio/video information, the control information including a first period for retaining the audio/video information on a recording medium and a second period for enabling reproduction of the audio/video information recorded on the recording medium after the audio/video information is initially accessed for reproduction from the recording medium;

a recorder which records audio/video information received by the receiver to the recording medium; and

a reproducer which reproduces audio/video information recorded by the recorder from the recording medium,

wherein the reproducer enables reproduction of the audio/video information from the recording medium in a case where an elapsed time from the recording of the audio/video information is within the first period and an elapsed time from the initial access of the audio/video information is within the second period, and disables reproduction of the audio/video information from the recording medium in a case where an elapsed time from the recording of the audio/video information is out of the first period even if the audio/video information is initially accessed for reproduction at a timing when a remaining time of the first period is less than the second period and an elapsed time from the initial access of the audio/video information is within the second period.

2. The recording and reproducing apparatus according to claim 1, wherein the first period is longer than the second period.

3. A recording and reproducing method for recording audio/video information to a recording medium and reproducing the audio/video information from the recording medium, the method comprising steps of:

receiving the audio/video information and a control information related to the audio/video information, the control information including a first period for retaining the audio/video information on the recording medium and a second period for enabling reproduction of the audio/video information recorded on the recording medium after the audio/video information is initially accessed for reproduction from the recording medium;

recording received audio/video information to the recording medium; and

reproducing recorded audio/video information from the recording medium,

wherein reproduction of the recorded audio/video information is enabled in a case where an elapsed time from the recording of the audio/video information is within the first period and an elapsed time from the initial access of the audio/video information is within the second period, and reproduction of the recorded audio/video information is disabled in a case where an elapsed time from the recording of the audio/video information is out of the first period even if the audio/video information is initially accessed for reproduction at a timing when a remaining time of the first period is less than the second period and an elapsed time from the initial access of the audio/video information is within the second period.

4. The recording and reproducing method according to claim 3, wherein the first period is longer than the second period.

5. A recording and reproducing apparatus, comprising:

a receiver which receives audio/video information;

a recorder which records audio/video information received by the receiver to the recording medium; and

a reproducer which reproduces audio/video information recorded by the recorder from the recording medium according to a control information related to the audio/video information, the control information including a first period for retaining the audio/video information on a recording medium and a second period for enabling reproduction of the audio/video information recorded on the recording medium after the audio/video information is initially accessed for reproduction from the recording medium,

wherein the reproducer enables reproduction of the audio/video information from the recording medium in a case where an elapsed time from the recording of the audio/video information is within the first period and an elapsed time from the initial access of the audio/video information is within the second period, and disables reproduction of the audio/video information from the recording medium in a case where an elapsed time from the recording of the audio/video information is out of the first period even if the audio/video information is initially accessed for reproduction at a timing when a remaining time of the first period is less than the second period and an elapsed time from the initial access of the audio/video information is within the second period.

6. The recording and reproducing apparatus according to claim 5, wherein the first period is longer than the second period.

7. A recording and reproducing method for recording audio/video information to a recording medium and reproducing the audio/video information from the recording medium, the method comprising steps of:

receiving the audio/video information;

recording received audio/video information to the recording medium; and

reproducing recorded audio/video information from the recording medium according to a control information related to the audio/video information, the control information including a first period for retaining the audio/video information on a recording medium and a second period for enabling reproduction of the audio/video information recorded on the recording medium after the audio/video information is initially accessed for reproduction from the recording medium,

wherein reproduction of the recorded audio/video information is enabled in a case where an elapsed time from the recording of the audio/video information is within the first period and an elapsed time from the initial access of the audio/video information is within the second period, and reproduction of the recorded audio/video information is disabled in a case where an elapsed time from the recording of the audio/video information is out of the first period even if the audio/video information is initially accessed for reproduction at a timing when a remaining time of the first period is less than the second period and an elapsed time from the initial access of the audio/video information is within the second period.

8. The recording and reproducing method according to claim 7, wherein the first period is longer than the second period.
