Studio to Transmitter Digital Link


STL (Studio to Transmitter video links) are Point-to-Point microwave links to transport digital TV Programs (in ASI or IP formats).
The links operate in the frequency bands from 2 to 30 GHz and can be used at line-of-sight distances of up to 50 miles (80 Kilometers), depending on options such as frequency band, output power, modulation format and antenna size.
The STL can transport from one to four ASI streams or its equivalent in IP format. Each ASI stream transports from one to six video programs simultaneously, SD or HD.
An optional ENCODER is used to generate ASI streams by multiplexing video from the Studio, which can be provided in SDI or HDMI format. The output of the link is ASI or IP to be fed directly to the TV transmitter.
