Researchers have developed UniGVC, a novel unified generative video codec that supports both high-quality, random-access decoding and low-delay streaming from a single bitstream. UniGVC-BI utilizes a bidirectional diffusion transformer with dense attention for quality-oriented playback, achieving state-of-the-art rate-distortion-perception trade-offs at extremely low bitrates. For real-time streaming, UniGVC-AR employs an autoregressive diffusion transformer with windowed attention, enabling significantly faster decoding speeds while maintaining competitive reconstruction quality.
