APPARATUS AND METHODS FOR CONTEXT BASED VIDEO DATA COMPRESSION
First Claim
Patent Images
1. A method of context based video acquisition by an autonomous mobile camera apparatus, the method comprising:
- acquiring video of a visual scene at a first data rate using the mobile camera apparatus;
producing lower rate video from the video, the lower rate video characterized by a lower data rate compared to the first data rate;
transmitting the lower data rate video via a wireless communications interface;
detecting an indication of interest associated with the video scene; and
in response to detection of the indication, storing the video at the camera apparatus at the first data rate.

Abstract
In some implementations, a camera may be disposed on an autonomous aerial platform. A user may operate a smart wearable device adapted to configured, and/or operate video data acquisition by the camera. The camera may be configured to produce a time stamp, and/or a video snippet based on receipt of an indication of interest from the user. The aerial platform may comprise a controller configured to navigate a target trajectory space. In some implementation, a data acquisition system may enable the user to obtain video footage of the user performing an action from the platform circling around the user.

5. A mobile camera apparatus, comprising:
-
a camera sensor configured to provide video at a full data rate; a circular memory buffer configured to store a portion of the video at the full data rate, the portion characterized by a first duration; a nonvolatile storage configured to store video at a reduced data rate for a second duration, the second duration being greater than the first duration; a communications interface configured to detect indications of interest associated with the video being acquired; and a processing component configured to produce and store video snippets in response the detected indications of interest by, based on an individual indication of interest; produce a video snippet, the video snippet characterized by the full resolution, the video snippet production comprising transferring the portion of video at the full resolution from the buffer to the nonvolatile storage; and store a time tag in a table in the nonvolatile storage, the tag associated with the video snippet; wherein; the nonvolatile storage is configured to store video at the full data rate for a third duration, the third duration being greater than the first duration and smaller than the second duration; and producing the video snippets enables the mobile camera apparatus to obtain video at the full resolution over a time period of at least the second duration. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A mobile video acquisition apparatus, comprising:
-
a camera component to provide video of a user; a nonvolatile storage capable to store the video for a first duration; a communications interface configured to detect an indication of interest of a plurality of indication of interest associated with the video being provided; and a logic configured to produce times stamps in response to detected indications of interest by, based on an individual indication of interest, produce a time stamp; wherein; the individual indication of interest is produced by a user wearable device based on an action of the user, the wearable device disposed remote from the video acquisition apparatus and in data communication with the video acquisition apparatus; the individual time stamp enables automatic access to a respective video snippet of the video stored on the nonvolatile storage corresponding to the individual indication of interest; the respective snippet being of a snippet duration; and a combined duration of snippet durations for video snippets corresponding to the detected indications of interest is smaller than the first duration. - View Dependent Claims (19, 20)
