  • 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.

  • Page 57 The possible indicator status values are: • OK: The transcoder session is operating normally (it has a valid input and is transcoding that input). • Waiting for Input: The transcoder session is configured and enabled, but it has no input. This can be because it has no connection to an input port, or because the port has no programs, or because the selected program is not available in the connected port.

  • Page 58: Connections

    The Connections configuration tab is depicted below. The message “No Connections” will be displayed if there are no configured input/output connections in the BBG-1090-TRX-MPEG. As indicated in the figure, the Connections configuration area is divided into two parts: a source selection, and a destination selection.

  • Page 59: Source Selection

    Source Selection The Source Selection area is available in the Connections tab, as well as in the Transcoder, ASI Outputs and IP Outputs tabs. This allows a connection to a given output to be established as part of the configuration actions for the output. The operation is the same regardless of the location of the control.
  • Page 60 In some situations, it may be desirable to identify the IP streams by their address/port combinations rather than using a name. This mode can be enabled by selecting Stream Addresses in the Stream Display control, as depicted below. This operation does not affect the user-defined names.

    o Auto-Select: This option is useful when the transport is not yet present, and the program numbers are unknown. If this option is selected, the BBG-1090-TRX- MPEG will select the first program found in the transport. When operating in an SPTS environment, it is sufficient to use this option for all connections.
