SYSTEMS AND METHODS FOR PARTITIONING A VIDEO FEED TO SEGMENT LIVE PLAYER ACTIVITY
A process to partition a video feed to segment live player activity includes receiving, on a first recurring basis, a transmission of a central video feed from a first camera. The central video feed is calibrated against a spatial region represented in at least two dimensions that is encompassed by the central video feed. The process includes receiving, on a second recurring basis, a respective time-stamped position information from each tracking device in a plurality of tracking devices. Each tracking device is worn by a corresponding subject on the spatial region and transmits positional information that describes a time-stamped position of the corresponding subject in the spatial region. The process uses the received information and the calibration to define a first sub-view of the central video feed associated with a first subject. The first sub-view comprises a corresponding sub-frame associated with the first subject.

obtain position information; and
a processor coupled to the communication interface and configured to:
determine, based at least on the obtained position information, a subset of each sequential frame associated with a first subject;
use the determined subset of each sequential frame associated with position information of the first subject to define a first sub-view of the central video feed, the first sub-view comprising for each of a plurality of frames comprising the central video feed a corresponding sub-frame associated with the first subject; and
cause the first sub-view to be communicated to a device configured to display the first sub-view.

the first sub-view is one of portrait orientation or landscape orientation, and
the central video feed is the other one of portrait orientation or landscape orientation.
11 . The system of claim 1 , wherein the first sub-view tracks the first subject as the first subject moves through a spatial region including by obtaining corresponding positional information.
12 . The system of claim 1 , wherein the first subject is selected by a user at a remote device.
13 . The system of claim 1 , wherein the first subject is selected automatically based at least in part on being within a threshold distance to a ball or other subject.
14 . The system of claim 1 , wherein the first sub-view is communicated independently from the central video feed.
15 . The system of claim 1 , wherein the first sub-view includes information related to an identity of the first subject, the identity is displayable, and the identity is selectable within the first sub-view for display.
16 . The system of claim 1 , wherein the processor is further configured to use the obtained position information and a calibration of the central video feed to define a second sub-view of the central video feed, wherein the second sub-view is associated with a second subject in at least one of: a same competition, a different concurrent live competition, or a historical competition.
17 . The system of claim 1 , wherein each subject in the first subject has a plurality of sensors configured to collect sensor data and the processor is further configured to:
identify a geometric center or other point or range of points based at least in part on the collected sensor data and collective tracking information for first subject; and
define the first sub-view based at least in part on the identified geometric center or other point or range of points.
