DEVICES AND METHODS FOR VIDEO ENCODING AND DECODING WITH RETENTION OF INFORMATION RELATED TO PPG Russian patent published in 2017 - IPC H04N19/167 H04N19/186 

FIELD: physics.

SUBSTANCE: video coding device (10) comprises the first encoder (20) to encode input video data (100) in accordance with the first coding scheme and the first coded video data output (120) with quality lower, than the input video data, and the second encoder (30) to encode input video data (100) in accordance with the second coding scheme which preserves data related to PPG, and the second encoded video data output (130).

EFFECT: preservation of significant PPG information after encoding without requiring large amounts of additional data.
