Broadcasting video and audio has rapidly developed from the send-and-forget type transmission to the full duplex OTT and VOD models in recent years. The inherent bi-directional capabilities of IP networks have provided viewers with a whole load of new interactive viewing possibilities.
Synchronizing became extremely important with the growth of AC power systems, which ended up being used to synchronize all sorts of equipment, from Radar to television.
The features we love about OTT services – such as combined linear and on-demand content, multi-device viewing mobility, tailored viewing experiences, and in some cases better resolutions – are driving the general rapid uptake of OTT services.
In this second instalment of our extended article looking into the practical applications of SDI and IP we look at how SDI is naturally plug-and-play and works with well-defined formats whereas IP is dynamic and more versatile but requires greater thought in making it work reliably.
