Participation in ongoing industrial projects and activities, for Laud Media AS (also one of the main shareholders):

• R&D in Ultra High Definition (UHD) TV/Video for use in numerous applications.
• R&D in HDCP (content protection) decoding and re-encoding for routing and distribution.
• R&D in proprietary protocols with error handling for embedded products control and firmware upload.
• Training and supervision of new R&D engineers in mentioned and related areas

A selection of my previous Research and Development activities:

For Lynghaug Electronic Design and Laud Electronic Design (from 1997):

• Development of cost-optimized routing-switchers with distribution possibilities for broadcast quality analogue- and digital audio, as well as analogue- and serial digital video (SDI).
• Development of firmware for microcontroller-based control-panels for the routing-switcher systems.
• Development of ADC- and DAC solutions for broadcast quality video, with built-in Gen-locked framestore.
• Development of modular video routing-switch systems with distribution possibilities for HD-SDI (SMPTE 292M) and 3GHD-SDI (SMPTE 424M) with bitrates of up to 3Gbit/s. Up to 256 inputs and 256 outputs.
• Development of modular distribution system for HDMI video with Full-HD and 4K resolutions, for TV-stores and similar applications.

For Ericsson (1996-1997):

• Development of analogue telephone-line interfaces for data modems.
• Development of development-kit (DK) for microcontroller ASIC.

For Sandar Electronics (1992-1996):

• Development of modular video routing-switch systems with distribution possibilities, for wideband analogue video in professional broadcast quality.
• Development of modular signal-switch systems with distribution possibilities for digital signals of 2Mbit/s, 8Mbit/s, 34Mbit/s, 140Mbit/s og 155Mbit/s telecom rates.
• Development of modular video routing-switch systems with distribution possibilities for serial digital video (SDI) according to ITU-R BT:656 and SMPTE 259M with bit-rates of up to 270Mbit/s.

For Tandberg Cryptovison (1990-1992):

• Development of PAL analogue video modulator- and demodulator-solutions for pay-TV set-top-boxes.
• Specification of digital filter and slicing solution for digtial data over analogue video-lines, for implementation in VLSI ASIC for new generation set-top-boxes.
