System and method for dynamically adjusting a recording bitrate to accommodate a writing speed of a storage device

A control system for controlling a data buffer with a buffer size to store data, configured to:

• store data at a selected storage bitrate into the data buffer;
• write the stored data from the data buffer into a storage device attached to the data buffer with a predetermined writing speed;
• monitor a data amount of the stored data in the data buffer;
• monitor a trend of change in the data amount;
• determine whether the data amount has reached a first ascending threshold, the first ascending threshold being below the buffer size of the data buffer;
• and
• in response to the data amount having reached the first ascending threshold and the trend of change in the data amount being an ascending change, reduce the storage bitrate in the data buffer.

An unmanned aerial vehicle, comprising,

• a vehicle body;
• a data buffer with a buffer size configured to store data and write the stored data into a storage device;
• and
• a control system, configured to:
• monitor a data amount of the stored data in the data buffer;
• monitor a trend of change in the data amount;
• determine whether the data amount has reached a first ascending threshold, the first ascending threshold being below a buffer size of the data buffer;
• and
• in response to the data amount having reached the first ascending threshold and the trend of change in the data amount being an ascending change, reduce the storage bitrate in the data buffer.
