Abstract
A recorder provides to a recorder/player via a high-speed bus content-related information such as a digital audio signal as information, a content ID being identification information on the digital audio signal and a standard playing time of the digital audio signal. The recorder/player has a controller which stores the content ID into a copy-history information management memory when the same content ID is not existent in the memory. The content ID is held for a period measured by a timer. For this period, the recording function of the recorder/player is limited so that the same digital audio signal cannot be copied at a high speed.
Claims26
A method for limited recording of an information signal, comprising the steps of:
- setting a time;
- recording a time-series signal;
- measuring an elapsed time from start of the recording step;
- comparing the measured elapsed time and the set time with each other;
- and
- limiting the recording step, after completion of the recording, if the comparison result shows that the present time is between the start of the recording step and the set time.
A method for limited recording of an information signal, comprising the steps of:
- setting a time;
- reproducing a time-series signal for a standard playing time;
- recording the time-series signal;
- measuring an elapsed time from start of the recording step;
- comparing the measured time and the set time with each other;
- and
- limiting the recording step, after completion of the recording, if the comparison result shows that the present time is between the start of the recording step and the set time.
A system for controlled recording of an information signal, composed of an information signal output device to provide as an information signal a time-series signal whose information content varies with time, for a time shorter than a standard playing time, and an information signal recording apparatus to record the information signal from the information signal output device, the information signal recording apparatus comprising:
- means for measuring an elapsed time from start of the recording;
- and
- a controlling means for comparing a preset time and the measured elapsed time with each other, and limiting the recording, after the information signal has been recorded, if the comparison result shows that the measured elapsed time is shorter than the preset time.
An information signal recording apparatus adapted to receive and record a time-series signal for a time shorter than a standard playing time of the time-series signal, the apparatus comprising:
- means for measuring an elapsed time from start of recording the time-series signal;
- and
- means for limiting re-recording of the time-series signal, after the time-series signal has been recorded and for a predetermined elapsed time measured by the time measuring means.
A recording apparatus comprising:
- means for receiving an information signal and a time information on the information signal;
- means for recording the information signal;
- means for measuring an elapsed time from start of the recording by the recording means;
- and
- means for comparing an elapsed time from start of the recording, set based on the received time information, and the measured elapsed time with each other, and disabling the recording means form recording the same information signal if the measured elapsed time is shorter than the set elapsed time from start of the recording.
A method for limited recording of an information signal, comprising the steps of:
- receiving an information signal and a time information on the information signal;
- recording the information signal into a recording medium;
- measuring an elapsed time from start of the information signal recording;
- and
- comparing an elapsed time from start of the recording, set based on the time information, and the measured elapsed time with each other, and disabling re-recording of the same information signal into the recording medium if the measured elapsed time is shorter than the set elapsed time from start of the recording.
A method for limited recording of an information signal, comprising the steps of:
- reproducing an information signal from a first recording medium;
- recording the reproduced information signal into a second recording medium;
- setting time information based on the reproduced information signal;
- measuring an elapsed time from start of the recording based on the recording step;
- and
- comparing the measured elapsed time and the set time information with each other, and disabling the recording, after the information signal has been recorded, if the measured elapsed time is shorter than the set time information.
