Abstract
In the broadcast video environment, it may sometimes be necessary to switch between 12G-SDI, which is a 12 Gbps interface on a single link, and quad-link 3G-SDI, which uses four 3 Gbps physical links. A routing switcher is disclosed herein that routes 12G-SDI signals between input ports and output ports. However, the apparatus also has the capability to receive quad-link 3G-SDI signals at its input ports and internally convert from quad-link 3G-SDI to 12G-SDI. The apparatus also has the capability to internally convert a 12G-SDI signal into a quad-link 3G-SDI signal for output on its output ports. Additional processing, such as link healing and/or deskewing of incoming quad-link 3G-SDI signals may be performed.
