Abstract

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.

Claims

1. A record mode setting apparatus for use in a video tape recorder, said video tape recorder including a tuner for detecting from a broadcasting signal a video signal which may include a VPS code indicating at least scheduled starting time of a program, recording means for recording the video signal detected by said tuner, and recording switch means for setting said recording means to be ready for operating, said record mode setting apparatus comprising:

VPS code deriving means for deriving the VPS code from a video signal detected by said tuner;

VPS setting switch means for setting a recording based on a VPS;

storing means responsive to operation of said VPS setting switch means for storing the VPS code derived from said VPS code deriving means; and

VPS control means for comparing the VPS code derived from said VPS code deriving means with an output from said storing means and being responsive to the result of the comparison for generating a control signal for controlling operation of said recording means which is ready for operating by operation of said record switch.

2. A record mode setting apparatus in accordance with claim 1, further comprising VPS mode setting means for detecting that both said record switch means and said VPS setting switch means are operated and making said VPS control means ready for operating.

3. A record mode setting apparatus in accordance with of claim 1, further comprising an inverting switch means and VPS mode switching means,

said VPS mode switching means preventing said control signal from being supplied from said VPS control means to said recording means in response to operation of said inverting switch.

4. A record mode setting apparatus in accordance with of claim 2, further comprising an inverting switch means and VPS mode switching means,

said VPS mode switching means preventing said control signal from being supplied from said VPS control means to said recording means in response to operation of said inverting switch.

5. A record mode setting apparatus for use in a video tape recorder, said video tape recorder including a tuner for detecting from a broadcasting signal a video signal which may include a VPS code indicating at least scheduled starting time of a program, a recording means for recording the video signal detected by said signal, a timer record switch means for setting said recording means to be ready for operating and setting the recording time period, and a timer means for determining the recording time period set by said timer record switch means and generating a signal for stopping recording by said recording means after a lapse of said recording time period, said record mode setting apparatus comprising:

VPS code deriving means for deriving the VPS code from the video signal detected by said tuner;

storing means responsive to operation of said timer record switch means for storing the VPS code derived from said VPS code deriving means;

VPS control means for comparing the VPS code derived from said VPS code deriving means with an output from said storing means and being responsive to the result of comparison for generating a control signal for controlling operation of said recording means which is ready for operating by operation of said timer record switch; and

VPS mode switching means for applying a control signal from said VPS control means to said recording means, said control signal overriding an output from said timer means.
