Sky Deutschland presenter Katharina Kleinfeldt at work at the SG Flensburg-Handewitt versus Frisch Auf G ppingen handball competition on 6 December 2020, live streamed using a dedicated 5G network from Telef nica O2

Sky Deutschland recently live streamed a handball match end-to-end over a dedicated 5G network provided by Telef nica O2 using LiveU's LU-Smart transmission app.

The live production took place on 6 December at the Flens-Arena in Flensburg, Germany, for a match between SG Flensburg-Handewitt and Frisch Auf G ppingen.

Telef nica O2 installed a dedicated 5G network to live stream the first league handball game, with a local 150MB (upload) 5G network on site for Sky Deutschland's end-to-end use case.

Supported by netorium, LiveU's long-standing partner in Germany, Sky Deutschland was able to capture the live action on the handball court and simultaneously transmit the live feed. Using Telef nica's high-performing 5G network on the production site, the video data was transmitted with maximum speed and bitrates.

LiveU's IP video technology delivered the live video content, enabling fans at home to watch the entire game in high quality with close-to-zero delay on Sky's online platform, skysport.de.

Uncovering potential

Alessandro Reitano, Sky Deutschland senior vice president for sports production and chairman of SVG Europe, tells SVG Europe: Our joint co-operation with Telef nica O2 has given us the opportunity to implement Europe's first end-to-end 5G production. We wanted to show the potential that is possible with the new mobile phone standard and decided, next to our classic' TV production, to produce the game with 12 5G smartphones.

This meant we could produce a completely different feed compared to usual, in order to make 5G a more tangible proposition for the viewer and also to enable us to perform a technical stress test to see to what extent 5G can already be used in the broadcast environment.

The 5G expansion of telcos in Germany is clearly progressing, so we see ourselves in a good geographical environment to be able to further take advantage of 5G opportunities going forward

Adds Reitano: We have had a good partnership with O2 for a long time and both companies stand for innovation. In this respect, we came up with the joint idea to create a real innovation with a first 5G transmission at the beginning of the year.

The first 5G multi-cam sports broadcast produced by Sky Deutschland was powered by technical partner for the project LiveU, which contributed its advanced IP video technology in form of the LU-Smart app. Sky Deutschland deployed several smartphones equipped with LiveU's proprietary software for real-time encoding and upstreaming to cover multiple camera angles.

A local 5G antenna and base station fed the signals from the smartphones via radio relay into the O2 media gateway, from where the 5G stream was delivered to the local OB truck.

The live feeds for the handball match were received via physical LiveU servers located in Sky's mobile control room outside the arena

The live feeds were received via physical LiveU servers located in Sky's mobile control room outside the arena. With each server providing four SDI output channels, the camera feeds could be fed into a hardware mixer and cut on the production site. The streams were then converted to HD-SDI with the help of Live-U.

LiveU's IFB feature (Audio Connect) served as the audio backbone for smooth, two-way communication between the control room and the field.

Reitano comments: For the implementation of the real-time graphics we used the Singular graphics platform for the first time for a live sports broadcast. To create graphics templates in such a flexible way was a big win for us.

The Sky Deutschland video stream confirmed the effectiveness of LiveU Reliable Transport (LRT) technology under real-life conditions, drawing on the insights gained by LiveU in pan-European 5G research projects.

Challenges and 5G future

There were a lot of challenges in creating such an advanced broadcast, Reitano explains: From a technical point of view, many questions had to be answered, such as what the dedicated 5G network set up should look like on site, what performance we could expect, how could network availability be ensured, and what special requirements had to be taken into account for end-to-end live transmissions, in terms of disaster recovery measures?

In addition, the smartphone devices - which run on 1080p - had to be brought together in our 1080i broadcast environment, he goes on. In terms of content, it was important to make the topic of 5G a tangible experience for customers and viewers and to make it accessible to them. The right storytelling was therefore key.

Said Alessandro Reitano, Sky Deutschland senior vice president for sports production and chairman of SVG Europe: We wanted to show the potential that is possible with the new mobile phone standard and decided, next to our classic' TV production, to produce the game with 12 5G smartphones.

5G definitely has a future within sports broadcasting, says Reitano. The changing viewing behaviour of our customers is more than a trend, and vertical content in particular is perceived more natively by smartphone users. The use of our content via mobile devices is subject to constant growth and has been manifesting itself for a long time. In this respect, we see productions like this as the next logical step to further enhance our product for our customers.

Yet, he adds: Conventional transmission will not replace this new type of production. It is ra
