Avatars in sign language - the next big thing? European research project "EASIER

What is the goal of the research project and where does it lead to? People who are completely deaf from birth communicate primarily through sign language. For them reading and writing is often difficult - it is like a foreign language. In the project "EASIER" a fully automated translation and communication tool will be developed, which enables deaf and hearing people to communicate and interact in sign language without barriers. The tool thus becomes an accessible link between companies/organizations and deaf people, e.g. at the point of contact on company websites. For example, the tool's workflow translates a video request in sign language into text form so that the text response from hearing people is again automatically translated and transmitted via avatar into sign language. In doing so, the research analyzes and considers the emotions and gender aspects in the language technology of seven sign languages and six spoken languages. The research project has a project duration from 2021 to 2023.

Speakers: Robin Ribback (Head of Innovation at SWISS TXT) will present the research project together with Michaela Nachtrab (Head of Department Business Development Accessibility) and Luca Marra (Project Manager Innovation Projects Accessibility).

For several years, SWISS TXT, the subsidiary and multimedia competence center of SRG SSR (Swiss Broadcasting Corporation), has been involved in national and European research and development projects in the areas of its core competencies "Digital Media Operation (DMO)" and "Accessibility". These are projects with a duration of 2 to 5 years. SWISS TXT concentrates on applied research.


NetBox - an open source software for managing and documenting infrastructure in IT and broadcast?

Infrastructure in the broadcast sector is becoming IT - or already is. This means having to manage a lot of cables, patch panels, racks, devices and IP addresses. NetBox is a powerful alternative to the huge Excel lists or plan PDF files that are currently often used. The software is open source and made for managing systems in data centers. Therefore it is also very interesting for the infrastructure of a radio station as a tool for documentation. With NetBox, IP networks and network structures can be mapped logically. Technical locations and racks can be modeled and devices can be created with all their connections. Cable paths can be traced across patches.

Currently, NetBox is mainly used in the IT and data center context. As a central data basis, processes can be simplified and errors avoided with simple web access and rights management. How the approaches and methods can be transferred to the broadcast area and how existing documentation can be adopted will be the topic of the presentation.

Alexander Votteler has introduced RelAix NetBox at the Aachen Internet provider and will report on the system and his experiences.


HDBaseT - Robust high-speed connectivity over low-cost infrastructure

Arno Distel, Valens

Moderation: Prof. Hans-Peter Schade, Klaus Sandig, FKTG

HDBaseT is a global standard for the joint transmission of uncompressed UHD video and audio, Ethernet, USB, control signals and power over a single cable even over longer distances. It is used in many application areas such as Professional AV, Automotive, Medical, Industrial.

After an introductory overview of HDBaseT, the presentation will show the technical tricks needed to solve the requirements and bring up typical use cases of HDBaseT. In addition, comparisons to IP-based transmission methods will be explained and how the various standards can complement each other.


Troubleshooting SMPTE ST 2110 Networks

Ralf Herrmann, Telestream LLC

Moderation: Prof. Hans-Peter Schade, Jürgen Burghardt, FKTG

SMPTE ST 2110 allows to manage uncompressed video, audio and data streams in real-time within IT networks and offers much higher flexibility as well as better scalability compared to classical SDI networks. However, the principles from IT technology that are applied to SMPTE ST 2110 signal transmission lead to a much higher complexity and multilayer. This in turn makes troubleshooting more difficult. In order to be able to narrow down errors purposefully, one should understand the processes involved in the transmission of media via the IT network. In addition, SMPTE ST 2110 network operators should develop appropriate strategies to quickly locate problems that occur within the media network. Real-time SMPTE ST 2110 measurement devices can simplify and accelerate fault analysis. In addition, monitoring systems can be used to monitor compliance with service level agreements (SLAs) and proactively report the occurrence of potential faults so that they can be resolved in a timely manner.

In the presentation, the basic concepts of ST 2110 will be explained and possibilities for monitoring as well as measuring media streams or the PTP (Precision Time Protocol) reference in the IP video network will be shown.


Applications of the SRT protocol

Lucas Gödel, Media Mobil GmbH

The application of the Secure Reliable Transport Protocol during the state elections in Saxony-Anhalt 2021

The Secure Reliable Transport Protocol (SRT) is a video streaming method based on the User Datagram Protocol (UDP), which enables low-latency image transmission over the public Internet. Its reliable error correction based on ARQ and FEC results in its low latency. For example, the transmission method was used in the state elections to replace the previous RNS lines. The operating system does not play a role in this case. Moreover, a stream using this method does not require additional hardware encoders or decoders. Also, no extensive informational knowledge is required. For these reasons, the experiment can even be carried out in one's own four walls at a later date with little effort. Finally, any open questions regarding the content of the webinar will be discussed.
