Abstract

An audio and/or video generation apparatus which is arranged in operation to generate audio and/or video signals representative of an audio and/or video source, the audio and/or video generation apparatus comprising a recording unit which records the audio and/or video signals on a recording medium, wherein the audio and/or video generation apparatus is arranged to receive metadata associated with the audio and/or video signals generated by a data processor, the recording unit records the metadata on the recording medium with the audio and/or video signals. The data processor receives signals representative of the time codes of the recorded audio/video signals, and the metadata includes time code data representative of the in and out points of a take of the audio/video signals generated by the data processor. The metadata also includes unique identification code for identifying the audio/video signals. The unique identification code is a UMID or the like.

Claims

1. A video camera comprising:

a lens;

circuitry configured to

record a video signal corresponding to a field of view of the lens on a recording medium,

generate metadata, the metadata including at least an indication of a resolution of the video signal, an image stamp and a marker generated during a recording process of the video signal for specifying a scene in the video signal, the metadata is recorded in association with the video signal; and

an interface configured to provide bi-directional wireless communication between the circuitry and a portable device and connectable to the portable device such that, when connected to the portable device, the interface is configured to communicate the image stamp to the portable device for display, and the interface is configured to receive data based on an input to the portable device, wherein

at least part of the metadata, which is recorded in association with the video signal, is generated based on the input to the portable device.

2. The video camera according to claim 1, wherein the image stamp is a representation of at least a part of the video signal.

3. The video camera according to claim 2, wherein the marker includes a good shot marker.

4. The video camera according to claim 1, wherein the circuitry is further configured to perform compression encoding processing in order to produce the image stamp.

5. The video camera according to claim 1, wherein the data includes pre-planned production information.

6. The video camera according to claim 1, wherein the image stamp is generated with the marker.

7. The video camera according to claim 1, wherein more than one image stamp associated with the generated video signal is communicated to the portable device for display.

8. The video camera according to claim 1, wherein the interface is configured to communicate using an infra-red signal.

9. The video camera according to claim 1, wherein the portable device is configured to display a graphical user interface for the input.

10. The video camera according to claim 1, wherein at least part of the metadata is generated based on a sensor.

11. A method for generating metadata, comprising:

recording, by circuitry of a video camera, a video signal corresponding to a field of view of a lens on a recording medium,

generating the metadata, the metadata including at least an indication of a resolution of the video signal, an image stamp and a marker generated during a recording process of the video signal for specifying a scene in the video signal, the metadata is recorded in association with the video signal; and

when an interface that is configured to provide bi-directional wireless communication between the circuitry and a portable device and connectable to the portable device is connected to the portable device,

providing, by the circuitry via the interface, the image stamp to the portable device for display, and

receiving, by the circuitry via the interface, data based on an input to the portable device, wherein

at least part of the metadata, which is recorded in association with the video signal, is generated based on the input to the portable device.

12. The method according to claim 11, wherein the image stamp is a representation of at least a part of the video signal.

13. The method according to claim 12, wherein the marker includes a good shot marker.

14. The method according to claim 11, further comprising:

performing, by the circuitry, compression encoding processing in order to produce the image stamp.

15. The method according to claim 11, wherein the data includes pre-planned production information.

16. The method according to claim 11, wherein the image stamp is generated with the marker.

17. The method according to claim 11, wherein more than one image stamp associated with the generated video signal is communicated to the portable device for display.

18. The method according to claim 11, wherein the interface is configured to communicate using an infra-red signal.

19. The method according to claim 11, wherein the portable device is configured to display a graphical user interface for the input.

20. The method according to claim 11, wherein at least part of the metadata is generated based on a sensor.

21. A system comprising:

a portable device; and

a video camera, including

a lens;

circuitry configured to

record a video signal corresponding to a field of view of the lens on a recording medium,

generate metadata, the metadata including at least an indication of a resolution of the video signal, an image stamp and a marker generated during a recording process of the video signal for specifying a scene in the video signal, the metadata is recorded in association with the video signal; and

an interface configured to provide bi-directional wireless communication between the circuitry and the portable device and connectable to the portable device such that, when connected to the portable device, the interface is configured to communicate the image stamp to the portable device for display, and the interface is configured to receive data based on an input to the portable device, wherein

at least part of the metadata, which is recorded in association with the video signal, is generated based on the input to the portable device.
