Our approach incorporates an IBP frame strategy for low-delay B-frame coding, a spatio-temporal fusion model based on state-space models for bidirectional temporal prediction, and an entropy-aware skipping mechanism that selectively omits coding certain latents to reduce entropy coding times. In addition to our model contributions we also implement two inference-time strategies that enhance compression performance. Experimental evaluation shows that DCVC-MB compares favorably to existing NVCs and traditional codecs. The method demonstrates BD-rate reductions of up to $8.98\\%$ on average compared to prior neural video codecs, and improvements of up to $30.45\\%$ and $1.81\\%$ over the VTM-19.0-LDP and VTM-19.0-RA(Inter-GoP=16) benchmarks, respectively, contributing to advances in neural video compression.", "url": "https://wpnews.pro/news/dcvc-mb-neural-b-frame-video-compression-using-state-space-models", "canonical_source": "https://arxiv.org/abs/2607.14305", "published_at": "2026-07-17 04:00:00+00:00", "updated_at": "2026-07-17 04:07:54.292179+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "computer-vision", "ai-research"], "entities": ["DCVC-MB", "DCVC-Mamba", "VTM-19.0-LDP", "VTM-19.0-RA"], "alternates": {"html": "https://wpnews.pro/news/dcvc-mb-neural-b-frame-video-compression-using-state-space-models", "markdown": "https://wpnews.pro/news/dcvc-mb-neural-b-frame-video-compression-using-state-space-models.md", "text": "https://wpnews.pro/news/dcvc-mb-neural-b-frame-video-compression-using-state-space-models.txt", "jsonld": "https://wpnews.pro/news/dcvc-mb-neural-b-frame-video-compression-using-state-space-models.jsonld"}}
