Digital Television now at UQ
Digital Television is online and streaming 24 hours per day thanks to Information Technology Services.
The University’s Central Video Replay System (CVRS) was digitized as part of a system-wide upgrade in late 2012. CVRS is a system many academics will be familiar with that plays media (e.g. DVDs) from a central source, eliminating the need to keep (and repair!) players in each lecture theatre. The upgrade allowed AV to also introduce Digital TV to UQ.
The Technical Details:
- Enables Delivery of Live TV to a PC
- Delivers each channel as a separate multicast stream reducing bandwidth impact.
- Equipment supports multiple video streams - One “Vision² MPEG-2/Digital TV Live device” can support three DVB-T or DVB-S transmitters or six QAM transmitters providing support for up to six transport streams (reducing the amount of hardware needed to supply multiple channels)
- IPTV streaming requires an output of around 300Mbps constantly via multicast to make all of the free-to-air channels available to the entire UQ network.
DTV was introduced to UQ by the joint efforts of the Audio Visual and Network Design & Engineering teams within ITS. It enables all staff to stream Free-to-air television at UQ.
