4K Ultra HD Blu-ray Disc Player, HDR, 3D, High-Res Audio, Wi-Fi, GA/Alexa control, silver. The Ultra HD Blu-ray Player UB424, equipped with the latest HCX processor, delivers an authentic cinematic experience in stunning 4K HDR picture quality on your TV. The HCX processor enhances dynamic images even on TVs without HDR when playing Ultra HD Blu-ray Discs. Its chrominance and color gradation processes have been finely tuned by the Panasonic Hollywood Laboratory. The selection of ultra-high-definition HDR content is continually expanding. The UB424 from Panasonic is future-proof with multi-HDR support. In addition to Hybrid Log Gamma for UHD television and the static HDR10 format, the player also supports HDR10+. This next-generation dynamic HDR standard optimizes the presentation of each individual scene through dynamic tone mapping, producing high-contrast images in unparalleled quality. Conventional HDR-compatible TVs use tone mapping to display HDR content with static metadata. However, depending on the TV manufacturer/model, this can lead to color gradations and details being unrepresentable, especially in darker image areas. The new Panasonic HDR Optimizer enhances tone mapping and distributes brightness within the displayable range, ensuring that even HDR10-standard content is optimized for playback. The technologies employed for Panasonic's unique 4K High-Precision Chroma Processing come directly from the Panasonic Hollywood Laboratory, the foundation for Panasonic's Blu-ray Disc research and development. Thanks to the high-performance processor, original 4K signals (4:2:0) are interpolated into an even more detailed signal output (4:4:4) through a multi-tap chroma process, resulting in greater depth and naturalness.
