VITEC introduces MGW Ace, the world's first HEVC / H.264 hardware encoder in a professional grade compact streaming appliance. MGW Ace's advanced HEVC compression enables users to stream broadcast quality HD/SD video with up to 50% bandwidth savings compared to today's H.264 standards.

Designed to support a diverse set of video streaming applications – MGW Ace features a wide range of inputs including HD-SDI, SDI, HDMI, DVI and Composite, user-intuitive web management software with full control of all H.265 compression settings. A secondary hardware based MPEG4-H.264 chip offers the ability to stream H.264 video in parallel to the network-efficient HEVC to support legacy systems.

MGW Ace boasts an all-hardware compression chip for real time encoding with advanced audio and metadata handling – all packaged in a portable device with low power consumption. MGW Ace makes it possible to take next generation HEVC encoding from the server rooms into the field for professional and industrial applications with easy integration to transport cases, TV trucks, military vehicles and aircraft.
