There are many different types of converters that can be used differently within a television studio.
SDI-to-HDMI converters, for example, are necessary if you wish to send any SDI signal to the studio or direction monitors.
Then there are Audio-to-SDI converters, which allow you to embed the audio signal to the video one.
SDI distributors can provide you with up to 8 identical outputs from just a single input,
without having to get a very expensive matrix for that.
SDI-to-Fiber converters allow you to send SDI signals to greater distances than those supported by the SDI itself.
There are also converters which allow you to edit the video format: when, for example,
all the signals in the studio are in HD but the transmission system is in SD.
