摘要： The record mode setting apparatus comprises a VPS setting switch (41), a VPS decoder (3), a code latch circuit (7), a VPS control circuit (26) and a code memory (27). When the VPS setting switch (41) is turned on while a recording means (16) is ready for recording, the VPS decoder (3) detects a VPS code out of a video signal and the VPS code is stored in the code memory (27). Thereafter, the VPS code detected by the VPS decoder (3) is applied to the code latch circuit (7). The VPS control circuit (26) compares the VPS code of the code latch circuit (7) with the VPS code stored in the code memory (27) and stops the recording means (16) when both do not coincide with each other.
