Video Encoding Subset Strategy for Power-Constrained Surveillance

The video encoding process is segmented into two distinct phases: a first phase where a subset of frames is encoded at full quality during capture, and a second phase where remaining frames are encoded later using stored data. This segmentation allows the system to manage energy consumption by performing intensive encoding operations only when necessary, rather than continuously encoding all frames at full quality.

The system performs preliminary actions by storing raw or partially processed video frames in memory during the capture phase, rather than encoding them immediately. This preliminary storage allows the encoding operation to be deferred to a later time when energy resources may be more available, reducing immediate energy consumption while preserving the ability to complete full encoding later.

The encoding process is divided into segments where only a subset of frames requires high-quality encoding during the capture phase, while other frames are encoded later. This segmentation reduces the instantaneous bitrate and power consumption during capture, as the system only processes a portion of frames at full quality rather than all frames continuously.

The system extracts the encoding operation from the continuous capture process. By separating the encoding function from the real-time capture flow, the system can perform encoding selectively on a subset of frames during capture, while deferring encoding of remaining frames to a later batch processing stage, thereby reducing instantaneous power and bitrate requirements.

The video processing workflow is segmented into distinct stages: a first stage where a subset of frames is encoded during capture, and a second stage where remaining frames are encoded using stored data. This segmentation improves processing efficiency by allowing the system to manage resource allocation across different time periods, performing intensive processing operations when resources are available rather than depleting them continuously.

The system performs preliminary storage of video frames in memory during the capture phase, preparing data for later encoding operations. This preliminary action allows the system to defer resource-intensive encoding operations to a later time, improving immediate processing efficiency while ensuring that all frames will ultimately be encoded for complete video output.
