Ryerson University leads development of global campus HD IP broadcast network

Toronto’s Ryerson University is pioneering the development of a CNN-style network for universities around the world using high-definition (HD) video streaming technology broadcast over IP networks.
Led by Ryerson’s Richard Grunberg, Director of Photography, Head of Video, and Assistant Professor in the School of Radio and Television Arts, the project represents the first truly collaborative international student perspective of worldwide events and creative endeavours. Prof. Grunberg initiated the research looking into the feasibility of using high-end HD video streaming technology to support the transmittal of broadcast quality content over IP networks, instead of costly satellite.
“With the aim of building a cost-effective ‘CNN’ of the university world, we hope to connect university channels and digital signage systems around the globe, to build a Canada-wide cable TV and trans-media platform, and to connect related researchers everywhere,” said Prof. Grunberg.
Using a new Ryerson broadcast adaptation of technology developed by Montreal-based HAIVISION, Prof. Grunberg recently carried out the first intercontinental tests between Ryerson and the Auckland University of Technology. Along ORION, CANARIE, KAREN (New Zealand’s research and education network) and standard high-speed internet connections, full 1080 HD content was transmitted both ways, with audio, IFB and Intercom, imperceptible delay, and all in one box with no image or sound breakup.
In the next few months, Prof. Grunberg will be busy presenting the Global Campus Network and associated technology at the upcoming Society of Motion Picture Engineers conference, the National Association of Broadcasters convention, and at a lecture at the Broadcast Educators Association meeting.
The Ryerson and New Zealand research collaboration follows earlier research and testing of ultra-high definition IP broadcast technologies over ORION, involving HAIVISION low-latency IP video gear, linking Ryerson, Sudbury’s Laurentian University and TFO, Ontario’s French-language educational broadcaster. The testing was profiled in a previous edition of the ORION newsletter (www.orion.on.ca/newsletter/may10/hdtest.html).
TFO is looking at using IP video and advanced networks to transmit broad production and broadcast interviews and other content. ORION has continued to collaborate with TFO and provided access to the network at ORION’s advanced network facilities over several days in December to facilitate ongoing testing of IP-based high-definition video.
