Processing

The established Socionext video processing devices (MB86M21, MB86M22, MB86M23) convert between Full HD (1920dots x 1080lines) H.264 video data and MPEG-2 video data within a 1.2W power budget for a H.264 translation. Also audio transcoding between various formats is supported. Due to their compact size, they can be used in a wide range of products, including mobile products such as smartphones and tablet PCs, as well as home digital broadcast recording equipment, such as TVs, hard disk PVRs, and PCs. See functional diagram and feature overview for MB86M2x below.
