Abstract
A recording control system for preventing undesirable copy of information reproduced from a video tape onto another tape. The system includes a unit for receiving audio and video information signals from a video tape reproducing apparatus, a circuit for receiving an identification code from the video tape reproducing apparatus, a circuit for receiving timing signals from the video tape reproducing apparatus, a circuit for decoding the received identification code with reference to the received timing signals to generate recording control signals, a unit for recording the received audio and video information signals onto a video tape, and a circuit for controlling an operation of the recording unit in response to the recording control signals.
Claims9
A recording control system for preventing undesirable copy of a recorded tape, comprising:
- a) means for receiving audio and video information signals from a video tape reproducing apparatus, said audio and video signals being sent to said recording control system by means of a plurality of transmission lines;
- b) means for receiving an identification code from said video tape reproducing apparatus, said identification code being sent to said recording control system along a first one of said plurality of transmission lines;
- c) means for receiving timing signals from said video tape reproducing apparatus, said timing signals being sent to said recording control system along a second one of said plurality of transmission lines;
- d) means for decoding said received identification code with reference to said received timing signals to generate recording control signals;
- e) means for recording said received audio and video information signals onto a video tape;
- and
- f) means for controlling an operation of said recording means in response to said recording control signals.
A recording control system for preventing undesirable copy of a recorded tape, comprising:
- 1) means for receiving audio and video information signals from a video tape reproducing apparatus;
- 2) means for receiving a pair of identification codes transmitted from said video tape reproducing apparatus by way of a pair of transmitting lines respectively;
- 3) means for generating recording control signals with reference to said received pair of identification codes, wherein both of said identification codes are used together to generate said recording control signals;
- 4) means for recording said received audio and video information signals onto a video tape;
- and
- 5) means for controlling an operation of said recording means in response to said recording control signals.
