High-end 4K projection chipset, with 4K@60 Hz keystone correction and 4Kp120 decoding
Hi3751V811Y is a great fit for high-end 4K LCOS, DLP, or LCD smart projectors, and is packed with premium features:
• Full support for parallel audio and video standards, such as AVS3, Audio Vivid, HDR Vivid, and ChinaDRM
• Powerful encoding and decoding capabilities capable of 8Kp30/4Kp120 decoding with popular decoding protocols such as AVS3, H.265, and AV1
• Big-Little multi-core architecture and 64-bit 2 x Cortex-A73 + 2 x Cortex-A53 CPUs to support high-speed computing in diverse complex home scenarios
• Mali-G51 MP4 GPU capable of 4K UI and 3D rendering
• Large bandwidth to support higher memory capacity and smoother system operations
• Algorithms that improve the clarity, color, contrast, and smoothness, including the upgraded HiSilicon-developed PQ algorithm, AI PQ algorithm, and 4K@120 Hz MEMC
• 4K@60 Hz keystone correction algorithm that delivers quality similar to that provided by hardware-based keystone correction while reducing the cost of the device
