Methods and apparatuses for fault recovery of video data

A method, comprising:

• receiving, from a first camera from a plurality of cameras and at a second camera from the plurality of cameras, a first parity data generated by the first camera based on first video data captured by the first camera, the first video data stored (1) as part of a first data stripe from a plurality of data stripes that is associated with the plurality of cameras and (2) in a first data storage medium operatively coupled to the first camera;
• modifying, at the second camera, the first parity data to generate a second parity data based on the first parity data and second video data captured by the second camera, the second video data stored (1) as part of the first data stripe and (2) in a second data storage medium operatively coupled to the second camera and not directly accessible by the first camera;
• and
• sending, from the second camera and to a third camera from the plurality of cameras, the second parity data to cause the third camera to generate a third parity data based on the second parity data and third video data captured by the third camera, the third parity data stored (1) as part of the first data stripe and (2) in a third data storage medium operatively coupled to the third camera and not directly accessible by the first camera and the second camera, the third video data stored in the third data storage medium as part of a second data stripe from the plurality of data stripes and not as part of the first data stripe.

An apparatus, comprising:

• a memory;
• and
• a processor operatively coupled to the memory, the processor configured to:
• receive, from a first sensor from a plurality of sensors and at a second sensor from the plurality of sensors, a first parity data generated by the first sensor based on first sensor data captured by the first sensor, the first sensor data stored (1) as part of a first data stripe from a plurality of data stripes that is associated with the plurality of sensors and (2) in a first data storage medium operatively coupled to the first sensor;
• modify, at the second sensor, the first parity data to generate a second parity data based on the first parity data and second sensor data captured by the second sensor, the second sensor data stored (1) as part of the first data stripe and (2) in a second data storage medium operatively coupled to the second sensor;
• send, by the second sensor and to a third sensor from the plurality of sensors, the second parity data to cause the third sensor to generate a third parity data based on the second parity data and third sensor data captured by the third sensor, the third parity data stored (1) as part of the first data stripe and (2) in a third data storage medium operatively coupled to the third sensor, the third sensor data stored in the third data storage medium as part of a second data stripe from the plurality of data stripes and not as part of the first data stripe;
• receive an indication that the second sensor data has become inaccessible;
• request the third parity data in response to detecting that the second sensor data has become inaccessible;
• and
• receive the second sensor data in response to a request and based on the third parity data.
