I am working on several solutions for professional DVB/MPEG systems (linear broadcasting) and narrowcasting. Transport stream analyzers, monitoring and mosaic systems are used in professional services, NOC and digital headends. Narrowcasting as part of a broadcast equipment, containing a professional rss playout system and also an infotv system for MSE. Including UDP/RTP streaming, (de)multiplexing, video encoding, decoding, video overlay, crawlers, logo insertion, etc. We use Dektec (DTAPI), Mainconcept for encoding/ decoding, Magewell for SDI or HDMI inputs and Medialooks for video image overlays, runs 24x7, stable as a rock!

As software architect/engineer and owner of Dualz Software BV, I developed SAM/SMART, a product for analyzing, visualization and monitoring service broadcasts (audio, video, data) in the DVB linear broadcast domain. This product in a 24x7, distributed environment, reports alarms and interfaces with external devices, using standard interfaces like SNMP, and dedicated interfaces. Indepth analysis can be done on transport streams. The multiviewer shows picture, vumeters, alarm indication panels, clocks, EPG info, etc. Also transcoding and streaming video are implemented. Related topics: DVB, MPEG2, MPEG4, H.264, DVB-S/S2, DVB-T/T2, ASI, ISDB-T, ATSC, ECM, ETSI TR290, Multiviewer, mosaic, CA, PSI/SI, loudness, OTT, SNMP, streaming video, Dektec, DTAPI, ... The multiviewer can be encoded and sent via live streaming over the internet in UDP, RTMP, RTSP or whatever appropriate protocol. Programming languages and tooling: C++, C#, Delphi, SOAP, Microsoft Visual Studio, DirectShow, Windows SDK, Microsoft Media Foundation Other tooling: SVN, tortoise, TRAC 'SAM' or 'SMART' was initially developed together with Impeq Technologies. In september 2014, Axon Digital Design bought non-exclusive development rights of the SAM product, and since then the product is also available as "SMART DVB", marketized bij Axon in the professional TV broadcasting area, In March 2019, Dualz Solutions became owner of the complete SMART product. SAM is the software-only (lite version), SMART the broadcast industry solution, including hardware and SLA services. See also our company site: www.dualz.com

As a software developer, I was responsible for the video layer, bringing hundreds of RTSP camera feeds to the edge system, and feeding them to the NVIDIA AI core for object detection. Using GStreamer, Deepstream and internal pipelines,build in python and C/C++. I created GStreamer plugins in C/C++, test cases, CI/CD, unit testing, system testing. Technology AWS KVS, signaling channels, webRTC, HLS streaming, and more.
