In 2021 Czech TV refurbished their flagship OB van HD1. Much of the original technology of 2008 got exchanged, but the forever-young VSM control system by Lawo stayed. Due to its almost unlimited possibilities in terms of communication protocols, configuration versatility, high virtualization level Czech TV insisted that this core of this truck persists. Therefore, to adapt to the recent major changes in OB van, ELEKTRONIKA provided professional VSM commissioning to establish control connections to new Riedel MediorNet Micron UHD distributed router, multiviewer, processing and stagebox in one. Ember+ protocol is an open protocol pioneered by Lawo but now extensively used across the industry to allow for extensive parameter exchange among various systems in broadcast. Apart from MediorNet, VSM in HD1 integrates with Grass Valley Kahuna on multiple Tally colors and EVS video servers.
