In this demo by Qualcomm AI Research, we showcase the world’s first neural inter-frame HD video decoder that runs at 30 frames per second on a mobile device. Inter-frame decoding is more complex but provides more bit-rate savings since it uses a reference frame, which is usually the previous decoded frame, to facilitate the coding process. We overcame the challenges of running an inter-frame neural decoder on a mobile device by introducing a novel efficient architecture, using AIMET for quantization-aware training, and running entropy encoding in parallel. Neural codecs offer a lot of potential to address the growing demand to compress data so stay tuned for more advancements coming from Qualcomm AI Research.
