Overview
External Router
Masterpiece has the mechanism to expand the number of sources coming into the mainframe
using an external router. This is primarily due to a system setup running in UHD. Using this new
feature, the number of sources to be used with the Masterpiece, are expandable up to the size
of the upstream router.
Masterpiece Intelligent Tie Line Concept
Masterpiece deploys an intelligent “Tie Line” approach, the desired external router outputs
(destinations) are connected to Masterpiece inputs. These inputs on the Masterpiece and
destinations from the Router are treated as “Tie Lines”. Each Tie Line acts as a floating video bus
between the router and Masterpiece, they are intelligently assigned and used as required.
Source selection on any Bus is transparent to the operator, regardless form where the Xpt is
being made, i.e. in the external router, or in the Masterpiece itself.
The Masterpiece software knows what physical inputs / Tie Lines are allocated and what are
not being used on a bus. Masterpiece then assigns the Physical input /Tie Line to the desired
Bus upon a source selection. Masterpiece updates the upstream router's destination /Tie Line
with the selected source.
Source selection on any Bus is transparent to the operator. Once setup, the operator sets the
desired router source by selecting the appropriate router XPT on the required bus. The
selection on the external router and the Tie Line path into the Masterpiece is automated.
