Recordings & Results :
PSNC in cooperation with SURFnet prepared a demonstration presenting advanced streaming technologies required for transmission of ultra high-resolution multimedia streams. During the demonstration three scenarios were presented. The main one was transmission of 4K live stream at 60 frames per second (60p 4K) from studio arranged in Poznan to Amsterdam. In addition, the transmission of FullHD 3D live content was shown as well as FullHD H.323 videoconferencing system. Transmitted data streams required around 700 Mbit/s of network capacity in total. For the purpose of the demonstration a dedicated link was established. The link was based on the resources of the international HPDMnet organization which is dedicated for experiments related to the transmission of multimedia content. Whole 4K 3D equipment required to conduct the demonstration was provided by PSNC in scope of the VISIONAIR project, whose goal is to provide access to unique facilities offered by the project partners for the European scientific community. The main aim of the demonstration was to compare current and future forms of streaming and the presentation of 4K 60p technology, which has a chance to become a standard for television transmission due to ITU-R standards approved by the EBU (European Broadcasting Union).

Conclusions :
1. UHD technology was successfuly integrated in order to stream 4K 60p JPEG2000 compressed video from Poznan to Amsterdam. Several problems with synchronization, converters as well as SDI video modes incompatibility occured, however most of them were overcomed. Standards (ITU-R, EBU, SMPTE) weren't fully implemented by all devices. 2. People enjoyed both 4K and 3D HD visual experience – however 4K 60p was better because of higher resolution and frame rate. 3. The latency of the setup was acceptable for compressed streaming but might be difficult for videoconference or real time collaboration.
