Video coding device and method

A video coding device comprising:

• a processor;
• a memory storing non-transitory computer-readable instructions that, when executed by the processor, control the processor to:
• determine a current bit rate of a time-varying bit rate of a communication channel between a destination device and the video coding device;
• generate a current reconstructed frame and an encoded bitstream at least in part via inter-frame coding of a current input video frame of a sequence of input video frames using a previously-generated reconstructed frame generated at least in part via inter-frame coding of a previous input video frame of the sequence of input video frames, the current reconstructed frame being a compressed version of the current input video frame;
• when both (i) a subsequent bit rate of the communication channel, determined after said inter-frame coding of the current input video frame of the sequence of input video frames, is less than a threshold value and (ii) the current bit rate exceeds the threshold value:
• (a) downscale the current reconstructed frame to yield a downscaled reconstructed frame;
• and (b) append the encoded bitstream with a bit sequence representing the downscaled reconstructed frame.
