This paper explores the configuration space of Low Complexity Enhancement Video Coding (LCEVC) for 4K SDR content and the VVC reference software VTM as base layer codec. The configuration space is spanned using a sweep over multiple values for the base layer QP and the LCEVC parameters sublayer 2 st…
Most frame-based learned video codecs can be interpreted as recurrent neural networks (RNNs) propagating reference information along the temporal dimension. This work revisits the limitations of the current approaches from an RNN perspective. The output-recurrence methods, which propagate decoded fr…
This paper presents an extension and global optimization of a bit-allocation strategy for use in a low delay subband ADPCM-based audio coding scheme. The framework employed for the assignment of bits to subband quantizers is based on a subband level estimation of the signals used for the prediction…
