Abstract

An in-vehicle recording/reproduction device (121) records in a recording device a program which the user starts watching, and reads and reproduces the data when watching is permitted, such as, for example, when a vehicle is stopped. The in-vehicle recording/reproduction device (121) transmits recording information about recording, such as a program, a time, and the like, to an in-home recording/reproduction device (303). The in-home recording/reproduction device (303) records the same program as that recorded by the in-vehicle recording/reproduction device (121) based on the recording information. The in-vehicle recording/reproduction device (121) transmits to the in-home recording/reproduction device (303) reproduction information indicating which scene was last reproduced in the in-vehicle recording/reproduction device (121). The in-home recording/reproduction device (303) performs reproduction based on the reproduction information. Thereby, it is possible to watch the rest of the program which was watched in the vehicle, at home without missing a scene.

Claims

1. A recording/reproduction system comprising an in-vehicle recording/reproduction device and a recording/reproduction device which receive the same signal and can communicate with each other, wherein

the in-vehicle recording/reproduction device is provided in a vehicle,

the recording/reproduction device is provided outside the vehicle,

the in-vehicle recording/reproduction device comprises:

a first recording device into which data can be recorded and from which the recorded data can be read out;

a reproducing section operable to read and reproduce the data recorded in the first recording device;

a recording information transmitting section operable to, when starting recording the data in the in-vehicle recording/reproduction device, transmit recording/reproduction device recording information about the data which the in-vehicle recording/reproduction device started recording; and

a reproduction information transmitting section operable to transmit to the recording/reproduction device reproduction information indicating a time point where reproduction was stopped,

the recording/reproduction device comprises;

a second recording device of recording the same data as the data recorded in the in-vehicle recording/reproduction device based on the recording information transmitted from the in-vehicle recording/reproduction device; and

a reproduction starting section operable to start reproduction from the position where reproduction was stopped in the in-vehicle recording/reproduction device based on the reproduction information from the in-vehicle recording/reproduction device.

2. The recording/reproduction system according to claim 1, wherein the in-vehicle recording/reproduction device further comprises an unrecorded data transmitting section operable to recognize a recording start position in the recording/reproduction device, and transmit to the recording/reproduction device data which has not been reproduced in the in-vehicle recording/reproduction device and has not been recorded in the recording/reproduction device.

3. The recording/reproduction system according to claim 1, wherein the in-vehicle recording/reproduction device further comprising a data transmitting section operable to, after the recording information is transmitted, transmit to the recording/reproduction device data which is recorded for a predetermined time from start of recording, and

the recording/reproduction device further comprising a data receiving/recording section operable to record the data transmitted from the data transmitting section so that the data is continuously linked to the data which has already been recorded in the recording/reproduction device.

4. An in-vehicle recording/reproduction device which is installed in a vehicle and records and reproduces data based on an input signal, comprising:

a recording device into which the data can be recorded and from which the recorded data can be read out;

a reproducing section operable to read and reproduce the data recorded in the recording device;

a recording information transmitting means of section operable to, when starting recording the data in the in-vehicle recording/reproduction device, transmit to an external recording/reproduction device recording information about the data which the in-vehicle recording/reproduction device started recording; and

a reproduction information transmitting section operable to transmit to the recording/reproduction device reproduction information indicating a position where reproduction was stopped.

5. The in-vehicle recording/reproduction device according to claim 4, wherein the reproduction information transmitting section transmits the reproduction information before the vehicle is powered OFF.

6. The in-vehicle recording/reproduction device according to claim 4, wherein the reproduction information transmitting section transmits the reproduction information every time reproduction is stopped.

7. The in-vehicle recording/reproduction device according to claim 4, further comprising an unrecorded data transmitting section operable to recognize a recording start position in the recording/reproduction device, and transmitting to the recording/reproduction device data which has not been reproduced in the in-vehicle recording/reproduction device and has not been recorded in the recording/reproduction device.

8. The in-vehicle recording/reproduction device according to claim 4, further comprising a specialized button for activating at least one of the recording information transmitting section, the reproduction information transmitting section, and the unrecorded data transmitting section.

9. The in-vehicle recording/reproduction device according to claim 4, wherein a specialized menu for activating at least one of the recording information transmitting section, the reproduction information transmitting section, and the unrecorded data transmitting section, is displayed on an operation screen for operating the in-vehicle recording/reproduction device.

10. A recording/reproduction device which can communicate with an in-vehicle recording/reproduction device installed in a vehicle and records and reproduces data based on an input signal,

15. The recording/reproduction device according to claim 10, further comprising a data receiving/recording section operable to receive and record data before a recording start position of the recording/reproduction device from the in-vehicle recording/reproduction device so that the data is continuously linked to the data which has already been recorded in the recording/reproduction device.

16. In a system comprising an in-vehicle recording/reproduction device and a recording/reproduction device which receive the same signal and can communicate with each other, a recording/reproduction method for reproducing in the recording/reproduction device the rest of data which was reproduced in the in-vehicle recording/reproduction device, the method comprising the steps of:

causing the in-vehicle recording/reproduction device to, when the in-vehicle recording/reproduction device starts recording the data, transmit to the recording/reproduction device recording information for causing the recording/reproduction device to record the same data;

causing the recording/reproduction device to start recording the same data as the data recorded in the in-vehicle recording/reproduction device in accordance with the recording information from the in-vehicle recording/reproduction device;
