Livestream from Brussels, the capital of Europe

Live recording of a panel discussion and transfer of the mixed image signal into three parallel livestreams in German, English and French – realized by BMK.TV


The day before the event we started our way with over 2.0 m² technology towards the capital of Europe. We had with us: four complete HD camera units with HKB and tripods, image and sound mixing technology, image generator for titles and texting bands, intercom, Tally, live stream encoders, SSD recording technology, and countless boxes of accessories, cables, adapters and backups.


Before the event we had to set cameras, audio and video mixing technology and to lay countless meters of cable. For the recording were used four HD cameras, all the cameramen were connected via intercom with video directing and Tally red light served the moderator as orientation which camera is currently active.

In the picture directing were all the individual camera signals mixed and played out as a PGM signal. The picture and title generator provided the integration of pictures and bands with names and titles of speakers.

A specialty of this event was that German, English and French were spoken on stage and were simultaneously translated to the guests by three interpreters. From the house PA system we got the spoken word as a main sound and then additional three audio channels with the respective translations. Using the digital mixer, the original signal was mixed together with the three translations and also with the signal program (PGM), then it was sent through 3 stream encoders for the German, English and French live streaming.

The HTML code for the live stream player was released at the day of the conference on the website of the customer – whose name cannot be unfortunately mentioned here because of contractual reasons, and after final internal test of the video and audio transmission was the code shortly before the start of the event released to the public. Few weeks before the event we ran tests together with the IT and internet department whether our live stream player is compatible with the customer CMS (turned out to be successful).

As the customer wanted to make the event afterwards accessible to the general public, all individual camera signals and the program signal in HD were recorded and all this was – together with the detailed statistics of the live stream – given immediately after the end of the event to the customer.
