Abstract

A method for controlling video in a system includes receiving wirelessly at a stationary base station a low quality video from a mobile device, the mobile device configured to record both the low quality video and a high quality video of a same video stream, to store each of the low quality video and the high quality video, and to wirelessly transmit only the low quality video. The method includes analyzing the low quality video at the stationary base station and, based on the analysis, transmitting a signal to the mobile device to delete the low quality video and the high quality video from the mobile device, to allow overwrite of the low quality video and the high quality video from the mobile device, or to request transmission of the high quality video from the mobile device.

Claims

1. A method for controlling video in a system, comprising:

receiving wirelessly at a stationary base station a low quality video from a mobile device, the mobile device configured to record both the low quality video and a high quality video of a same video stream, to store each of the low quality video and the high quality video, and to wirelessly transmit only the low quality video;

analyzing the low quality video at the stationary base station; and

based on the analysis, transmitting a signal to the mobile device to delete the low quality video and the high quality video from the mobile device, to allow overwrite of the low quality video and the high quality video from the mobile device, or to request transmission of the high quality video from the mobile device.

2. The method of claim 1, wherein analyzing the low quality video includes determining whether the low quality video meets a transmission condition, and requesting the transmission of the high quality video from the mobile device based on determining that the video meets the transmission condition.

3. The method of claim 1, wherein analyzing the low quality video includes displaying on a visual display device the low quality video, and wherein a human user analyzes the low quality video displayed on the visual display device.

4. The method of claim 1, wherein analyzing the low quality video includes automatically analyzing digital data corresponding to the low quality video by a video analysis device.

5. The method of claim 1, wherein analyzing the low quality video includes determining whether the low quality video meets a overwrite condition;

and

transmitting a signal to the mobile device to indicate that the low quality video and the high quality video may be overwritten based on determining that the low quality video meets the overwrite condition.

6. The method of claim 1, wherein the low quality video is at least one of a low resolution video and a video having a low frame rate, and the high quality video is at least one of a high resolution video and a video having a high frame rate.

7. A method of controlling video in a system, comprising:

capturing video with a camera of a mobile video system;

generating a low quality video and a high quality video based on the captured video;

storing the low quality video and the high quality video in storage;

transmitting only the low quality video to a base station based on detecting a receiver of the base station within range of the mobile video system; and

allowing delete or overwrite of both the high quality video and the low quality video from the storage based on receiving from the base station a signal indicating that the low quality video is not necessary.

8. The method of claim 7, wherein the low quality video is at least one of a low resolution video and a video having a low frame rate, and the high quality video is at least one of a high resolution video and a video having a high frame rate.

9. The method of claim 7, wherein the low quality video and the high quality video are generated continuously while the camera is on.

10. The method of claim 7, further comprising:

receiving a time selection indicating a time in the video stream; and

transmitting only a portion of the low quality video stream within a predetermined time interval of the time selection.

11. The method of claim 7, further comprising:

transmitting a second low quality video to the base station; and

transmitting to the base station a second high quality video corresponding to the second low quality video based on receiving from the base station a request for the second high quality video based on an analysis of the second low quality video by the base station.

12. A video transmission system, comprising:

a vehicle having a mobile video system, comprising;

a camera configured to capture video images;

an encoder configured to generate a high quality video and a low quality video of captured video images;

storage that stores the high quality video and the low quality video;

a transmitter that transmits only the low quality video to a base station; and

a controller that controls the storage to delete each of the low quality video and the high quality video from storage based on receiving a signal from the base station that the low quality video is not necessary based on an analysis of only the low quality video.

13. The video transmission system of claim 12, wherein the transmitter is configured to transmit a second low quality video to the base station;

and

the controller is configured to control the transmitter to transmit a second high quality video to the base station based on receiving a request from the base station for the second high quality video based on analysis of the second low quality video.

14. The video transmission system of claim 12, wherein the low quality video is at least one of a low resolution video and a video having a low frame rate, and the high quality video is at least one of a high resolution video and a video having a high frame rate.

15. The video transmission system of claim 12, wherein further comprising a user input to generate a time indication signal, and

the controller controls the transmitter to transmit only a portion of the low quality video within a predetermined time interval of the time indicated by the time indication signal.

16. The video transmission system of claim 12, wherein the base station comprises a video playback unit to generate a visual display of the low quality video and a user input device to generate the signal that the low quality video is not necessary based on analysis of the low quality video by a user.

17. The video transmission system of claim 12, wherein the base station comprises a video analysis unit to analyze digital data of the low quality to generate the signal that the low quality video is not necessary based on analysis of the digital data of low quality video by a processor.
