Abstract

Abstract A method for controlling a double-deck VCR during a tape duplication operation includes the steps of sensing the recording speed of a tape in an A deck, determining if an input signal for establishing a recording speed to be used by a B deck during the copying operations is provided, and transmitting the established recording speed to the B deck. When an input for establishing the recording speed is not provided, the recording speed of the tape in the A deck is selected as the established recording speed and is transmitted to the B deck. The sensing step includes the step of displaying using OSD (on-screen-display) characters displayed on a display device, the recording speed of the tape in the A deck. The determining step includes to step of displaying the established recording speed using corresponding OSD (on-screen-display) characters on the display device. Thus, the method according to present invention prevents an undesirable influence on the quality of the tape copy produced in the B deck due to the difference between the playback speed and the recording speed during copying operations performed by the double-deck VCR.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 148 words
A method for establishing the copying speed of a double-deck VCR including a microcomputer for controlling the driving of servos of an A deck and a B deck and an on-screen display means for displaying characters, said method comprising the steps of: sensing a playback speed in said A deck and intermittently displaying said playback speed as corresponding OSD characters on said display means; checking for an input signal for establishing a recording speed in said B deck within a predetermined time, when the input for establishing said recording speed is provided during said predetermined time, displaying the established recording speed in said B deck by said OSD characters; transmitting the established speed data to said B deck; and when no input for establishing said recording speed data is provided, transmitting the same recording speed data as said playback speed in said A deck to said B deck.
Claim 2
Independent Claim 148 words
A method for establishing the copying speed of a double-deck VCR including a microcomputer for controlling the driving of servos of an A deck and a B deck and an on-screen display means for displaying characters, said method comprising the steps of: sensing a playback speed in said A deck and intermittently displaying said playback speed as corresponding OSD characters on said display means; checking for an input signal for establishing a recording speed in said B deck within a predetermined time, when the input for establishing said recording speed is provided during said predetermined time, displaying the established recording speed in said B deck by said OSD characters; transmitting the established speed data to said B deck; and when no input for establishing said recording speed data is provided, transmitting the same recording speed data as said playback speed in said A deck to said B deck.
Claim 3
Independent Claim 192 words
A method for controlling the double-deck VCR including first and second tape decks and first and second servos, respectively, said first tape deck coupled to a means of displaying OSD characters and said first and second tape decks being connected to a microprocessor operated in response to signals received from one of a keyboard and a means for remote control, said method comprising the steps of: sensing a playback speed of said first tape deck and intermittently displaying said playback speed as corresponding first OSD characters on said means for displaying OSD characters; checking for an input signal from said one of the keyboard and the means for remote control corresponding to an established recording speed for said second tape deck; when said input signal is provided: displaying the established recording speed as second OSD characters on said means for displaying OSD characters; and transmitting data corresponding to said established sped to said second tape deck after a first predetermined time period has elapsed; and when no said input signal is provided, transmitting data corresponding to said playback speed to said second tape deck after a second predetermined time period has elapsed.
Claim 4
Independent Claim 192 words
A method for controlling the double-deck VCR including first and second tape decks and first and second servos, respectively, said first tape deck coupled to a means of displaying OSD characters and said first and second tape decks being connected to a microprocessor operated in response to signals received from one of a keyboard and a means for remote control, said method comprising the steps of: sensing a playback speed of said first tape deck and intermittently displaying said playback speed as corresponding first OSD characters on said means for displaying OSD characters; checking for an input signal from said one of the keyboard and the means for remote control corresponding to an established recording speed for said second tape deck; when said input signal is provided: displaying the established recording speed as second OSD characters on said means for displaying OSD characters; and transmitting data corresponding to said established sped to said second tape deck after a first predetermined time period has elapsed; and when no said input signal is provided, transmitting data corresponding to said playback speed to said second tape deck after a second predetermined time period has elapsed.
