For broadcasters, IP has increasingly become a valid option which allows them cost effective choices and greater flexibility. Hence the trend has become that a growing number of broadcasters are choosing to move to IP.
Research however suggests, that at present, none of the broadcasters are operating in an all IP environment. Instead they are using a combination of SDI and IP equipment which is connected to an all IP network. Moreover, SDI/IP equipment can be used to connect the SDI equipment to the IP core network; however connecting this equipment to an IP network is expensive. Furthermore, it is also not necessary, since the equipment stays restricted within a studio or control room. Hence, the conversion of SDI signals to IP and back to SDI seems to be a futile effort.
Therefore a cost effective way to distribute signals between a baseband equipment is by using a baseband routing technology. Additionally, signal processing such as audio embedding onto SDI frame synchronization or SDI signals can be done on the baseband equipment instead of converting it to IP and processing and converting it back to baseband.
As a result, the most cost-effective distribution and routing system is expected to be compact SDI routers which are located within baseband islands. These routers do the job of MCR routers but they also offer a high level of redundancy which includes SDI processing capabilities. A connection of these baseband islands to the rest of IP network is then possible through an adaption equipment.
