Haivision – Makito X4 Video Decoder


The Haivision Makito X4 Decoder is a versatile real-time HEVC/H.265 and AVC/H.264 video decoder. Capable of decoding live video SRT, UDP and RTP streams at very low latency, the Makito X4 Decoder is ideal for live broadcast, bi-directional interviews, remote production, sports coverage, and real-time monitoring.

Support for metadata and slice-based encoding makes it an ideal solution for mission-critical video applications.


4K UHD or 4 x HD

Video Decoder for live low latency, broadcast quality streaming

The Makito X4 Decoder can receive up to four different 1080p50/60 HD streams, or a single 2160p50/60 4K UHD stream over IP – along with 16 channels of digital stereo audio per decode. Streams encoded with either 8- or 10-bit pixel depths and 4:2:0 or 4:2:2 chroma subsampling can be decoded and output as 12G SDI video for 4K content or HD video with up to four 3G-SDI outputs.

The Makito X4 Decoder can decode and output HDR video, with PQ or HLG transfer functions. For mission-critical video applications where low latency is critical, the Makito X4 Decoder can also be used to decode slice-based encoded video. It can be used to decode low-latency video streams from any Makito encoder including the Makito X4 Encoder and the Makito X1 Rugged.

The perfect companion to the Makito X4 Encoder, the Makito X4 Decoder leverages AVIWEST’s Makito X heritage for proven reliability, quality and innovation. Compatible with a variety of AVIWEST products and able to fit in the same chassis as other Makito X and X4 products, the Makito X4 Decoder provides a seamless end-to-end 4K over IP workflow at ultra-low latency. For mission-critical applications, slice-based encoding and decoding can significantly reduce latency even further.


Ensure seamless live production by maintaining synchronization when switching between multiple video and audio sources. AVIWEST Stream Sync makes it easy to receive live video and audio streams from a remote venue while maintaining sync for immediate use in live production workflows. Makito X4 Decoders with Stream Sync help provide a cost-effective alternative to deploying large teams of personnel and resources to remote event locations.


Available as an appliance or blade, the Makito X4 Encoder and Decoder pack lots of power into a small form factor. Makito X4 Decoder blades offer the highest channel density available at a low cost per channel with 84 HD or 21 4K UHD SDI video outputs in a single 4RU rack chassis.


The Makito X4 Decoder is compatible with the AVIWEST EMS (Element Management System), a web-based solution for centrally managing AVIWEST Makito X, X1 Rugged, and X4 Series of video encoders and decoders.

Providing a significant boost in operational efficiency, AVIWEST EMS allows you to monitor device statuses, assign tags to group and filter based on a device’s function or location, as well as performing upgrades to individual devices or batch upgrades to multiple devices across different locations.


Secure Reliable Transport

With native support for the SRT protocol, the Makito X4 Video Encoder and Decoder are designed for live low latency streaming over the public internet and private networks to provide broadcasters with a secure, flexible, and cost-effective alternative to satellite and dedicated fiber.

AVIWEST-developed, SRT provides end-to-end security, resiliency and dynamic endpoint adjustment based on real-time network conditions to deliver the best video quality at all times.
