Hantro G1 Block Diagram

Hantro G1 multi-format hardware decoder brings an unprecedented level of format and resolution support to enable all kinds of video applications. It is also the first hardware decoder in the market to support Google’s VP8 video format for WebM and WebRTC applications, significantly extending the video playback time of Internet-connected and HTML5-enabled battery operated devices.

Intended for chips powering multimedia devices (smart phones, features phones, portable media players, tablets/netbooks, DVD/Blu-ray players, STB, car infotainment, etc.), Hantro G1 is built on silicon-proven designs deployed in hundreds of millions of chips worldwide, providing semiconductor manufacturers with a minimal risk solution for integrating high performance video capability into their chips.

Hantro G1 decoder design is exceptionally fast, requiring around 100MHz clock frequency to decode 1080p video at 30 fps, and can achieve 60fps decode for 1080p video in real life conditions. We also provide a multi-core version of Hantro G1 allowing 4K x 2K @ 30/60 frames per second.

Hantro G1 supports unlimited multi-format, multi-channel decoding, enabling simultaneous playback of up to ten SD streams. It uses unique pre-fetching and buffering mechanisms to enable smooth operation with low-end SDRAMs, realizing significant savings in power and overall chip design and manufacturing costs.


Hantro G1 is market’s lowest power video decoding solution consuming less than 30 mW for full HD video decoding, and just around 5 mW for SD video decoding.
