    Introduction This manual covers the following products:  The MVN-XC440 openGear™ Broadcast Transcoder card  The ITV-XC440c standalone Broadcast Transcoder appliance Both products have the same set of features, and essentially the same user interface. Unless specifically indicated, all features and controls described in this manual apply to both products.

  • Page 12  Regardless of the Automatic/Manual mode, the operator always has the ability to instruct the unit to switch to the other transport stream. An IP Input receives a transport stream over UDP/IP or RTP/UDP/IP, on a given IP Address/UDP Port combination, with an optional Source IP address specification. For each IP Input, the unit allows an optional backup IP Address/UDP Port/Optional Source IP Address combination to be specified.
