1.3 Operating Environment
CLEARcut Studio software runs on the same computer as the NMX Digital Service Manager
Server. NMX manages the encoders. You can hook up multiple encoders to the CLEARcut
workstation via a network switch. If resources are available, CLEARcut records multiple clips
in parallel.
CLEARcut Studio communicates with the encoder using the SCTE104 and SCTE-35
protocols, which are used by digital program insertion (DPI) messages. The MPEG output
from the encoder is sent to the CLEARcut workstation over a multicast IP address.
CLEARcut Storage Encoding Solution supports one VTR, VDR, or DVD player at a time.
CLEARcut allows the creation of a metadata package through the CLEARcut MetaData Editor.
A graphical user interface guides you through the process of creating the related asset
packages as defined in either CableLabs Video-on-Demand (VOD) Metadata Content
Specification 1.0 and 1.1 or Microsoft IPTV VOD Metadata Specification 1.1.
