Allegro DVT’s AL-E120 is a real-time, true multi-format hardware encoder IP supporting H.264/AVC, H.265/HEVC (SHVC), VP9 video codecs and JPEG still image standard. The AL-E120 encoder IP brings support for HEVC scalable extension (SHVC) and video quality improvement by 15% on average compared to Allegro DVT’s previous generation encoding IP. It also features a unique architecture, scalable from HD to up to 8K resolution.
