Video compression at extremely low bit rates

Traditional video compression standards include AVC, HEVC, VVC, and AVS. These algorithms may result in ringing and blocking artifacts at extremely low bit rates, which can seriously affect video transmission quality. To address these issues, we propose a novel video compression method that combines super-resolution technology with traditional compression standards. In the encoder, we first down-sample the high-resolution input video and then use the HEVC algorithm to encode the low-resolution video into a bitstream. In the decoder, the HEVC algorithm decodes the received bitstream and inputs it into a super-resolution network to reconstruct the original high-resolution video. On the one hand, transmitting low-resolution video can reduce the required bandwidth, effectively mitigating the impact of ringing and blocking artifacts at extremely low bit rates. On the other hand, super-resolution technology can filter out ringing and blocking artifacts during the process of restoring high-resolution video. The experimental results show that our proposed method can achieve a better PSNR performance than the traditional HEVC algorithm on the standard HEVC Dataset.
