Joint Screening Not Only for the Disabled

Prague, 13 October 2017 The CESNET Association has participated in a special joint screening of a film directed by Jan Svěrák entitled Po strništi bos (Barefoot) in the Prague cinema Aero, in Hradec Králové’s Bio Central, and in the University Cinema Scala in Brno. The screening was intended for both disabled and regular viewers.

Although the technology for viewing closed captions and descriptive audio tracks has only been installed in a few select cinemas in the Czech Republic, a special release print of the film was produced with captions and a descriptive audio track embedded directly in the video. This allows for the film to be projected anywhere, even if the required technology is not available. The first screening took place on 4 October in the Aero cinema, where it was presented by Petr Vítek, founder of the project, Luboš Krapka, Director of the Mathilda Foundation, and Jan Svěrák, director and producer of the film.

The presentation was interpreted into sign language and simultaneously transcribed onto the screen, as viewers with visual and hearing impairment were among the invited. In addition, the entire introduction was live-streamed into the University Cinema Scala in Brno and Bio Central in Hradec Králové. The live-streaming was fully implemented by the CESNET Association.

Live-streaming of the presentation and the subsequent discussion required the recording of the speakers and the sign language interpreter, as well as simultaneous transcription onto the screen, which was relatively challenging due to space constraints. The recorded video and audio were transmitted using UltraGrid multimedia transmission software developed by CESNET. The software makes it possible to adjust the quality of video and other parameters based on the transmission path between the sites.

A total of 400 viewers attended the joint screening in the three cinemas, and around CZK 21,000 was collected in voluntary admissions. The entire collected amount was passed onto the Mathilda Foundation for further projects for disabled viewers.
