4Kp60 STB chipset

Hi3798MV310 is a high-performance UHD 4Kp60 SoC for IPTV and OTT STBs. It packs a quad-core 64-bit Cortex-A53 processor, a multi-core 2D/3D acceleration engine, and a wide range of peripheral interfaces, such as USB 2.0 and SDIO 3.0.

The high-powered SoC offers cutting-edge audio and video features: H.265/AVS2 4K x 2K@P60 10-bit UHD video decoding, H.265/H.264 HD video encoding, HDR video decoding and display, and Dolby and DTS audio processing.

The SoC is engineered to help customers deploy UHD 4K services, that stand out by virtue of picture quality, stream compatibility, video playback, and overall system performance.

It can well to accommodate the growing demands for such value-added services as video communications, cloud gaming, and multi-screen interaction.
