Hi3531 Codec Processor

Description :

The Hi3531 is a professional high-performance SoC designed for multi-channel D1 and HD DVR and NVR. With the embedded high-performance dual-core A9 processor, H264 codec engine (supporting a maximum of 5-channel 1080p real-time codec complying with multiple protocols), and dedicated TOE network acceleration module, the Hi3531 meets the rising demand for HD and network applications. The Hi3531 also provides outstanding video pre-processing and post-processing features, various codec algorithms, and multi-channel HD output capability. These features guarantee users a high-quality image experience. In addition, the Hi3531 supports multiple integrated peripheral interfaces to meet customer requirements for functionality, features, and image quality, while reducing the cost. By
using the dedicated video cascade technology, Hi3531s and Hi3532s can be cascaded to provide superior encoding and decoding capabilities.
