ND Processing Engine

Signal Orchestration Glue for NDI


ND Processing Engine is modular infrastructure to facilitate migration of SDI to NDI workflows, and to enable a new generation of NDI based facility.  It aims to replace racks full of traditional SDI glue modules, commonly used for tasks such as scaling, bug insertion, audio embedding, de-embedding and mixing, plus other video and audio processing including unlimited flexible multiviewers and a fully integrated vision mixer, an AI Mix automated Video Follows Audio Controller, and a Virtual Camera Crew for deriving PTZ regions of interest in a locked off UHD shot. To complete your production workflow, ND Processing Engine also offers 4, 8 and 16 Channel Intercom modules, compatible with NDI, DANTE, and AES67 devices, plus analog audio via PCI/USB audio interfaces.


It can also be used to bridge between other IP video formats, with modules to perform tasks including AES67, RTP H.264/AAC Video/Audio stream conversion to NDI and NDI restreaming as various IP Stream formats including as transport streams.

ND Processing Engine also includes SRT transmit and receive modules to enable reliable transport of MPEG Transport Streams across continents between Processing Engine systems.


More details of the Processing Engine and all its modules are available in this white paper.


As part of a migration program from SDI to IP Video, ND Processing Engine can massively reduce costs, and rack space by replacing massive amounts of dedicated video hardware with generic COTS computing systems. A fast dual CPU Xeon or i9 computer can do the work of an entire floor to ceiling rack of traditional processing modules, all configured in a web browser from a generic pool of CPU resources. The entire signal chain can be reconfigured in seconds - using the same hardware to perform a completely different set of functions, in a different configuration.


The ND Processing Engine includes an AES67 to NDI Gateway to instantly re-wrap all your AES67 audio sources as native NDI Sources, and a complementary module to stream back to AES67 devices which support traceable clocks.  It also includes Sienna NDI WebLink to provide web browser based viewing of any NDI sources on your network - even from iPhone or iPad.


Sienna ND Processing Engine comes with a standard set of processing modules, with more specialist modules available in the PLUS add-on option.  Custom module development is also available to maximise efficiency of your workflow, and to explore even more technical capabilities of this amazing platform.
