摘要： A time lapse VTR carrying out field extraction recording includes a gate for extracting intermittently a supplied video signal at a ratio of one field to every three fields, a switching circuit for designating selectively a tape running speed of either 1/9 or 1/12 the tape running speed of a SP mode in the VHS system, and a servo control circuit for driving a capstan motor to run a magnetic tape at the designated tape running speed. The video signal extracted intermittently by the gate circuit is recorded at an azimuth angle differing from each field by a plurality of video heads on a magnetic head running at the designated tape running speed. As a result, the reproduction compatibility of a magnetic tape having field extraction recorded by a time lapse VTR with an EP mode of a conventional VTR of the VHS system is ensured.

摘要： A video tape recorder includes a microcomputer, an input terminal and a decoder. Its mode of operation can be determined by selectably applying one of a set of different voltages at the input terminal thereby causing the decoder to transmit an appropriate signal to the microcomputer. If a preselected voltage such as the ground voltage is applied at the input terminal, the decoder outputs a reset signal to thereby reset the microcomputer without the need for a dedicated reset switch.
