一、Hi2318/Hi2318M Chip is introduced

Hi2318 is a high-performance, highly integrated media playback chip integrated with 32-bit embedded MCU, built-in 256Mb capacity DDRI, with TV as the display terminal.

The Hi2318 integrates a high-performance hardware JPEG decoder capable of handling JPEG images up to 64M pixels.

Hi2318 internal integration of high performance video decoding engine, can support MPEG/1/2/4, H.264,AVS,AVS+ series of video format decoding.

Hi2318 built-in hardware audio decoding engine, can support MP3, WMA and other audio format decoding.

The Hi2318 supports the USB2.0 OTG interface and can be used as a device to connect to a PC or as a master controller to read USB flash disks.

The Hi2318 has built-in DTMB demodulation and is highly integrated.
