  • Page 17: Searching For Streams

    4.2 Searching for streams For an ever-increasing number of flows through a unit searching for information gets critical. In the DMG applications this has been put into the system from the very start. On top of the input application pane there is a search field which enables the operator to search and filter the list view in order to find the correct sources.

    9.1 SDI - Configuration application The SDI Configuration application essentially determines the flow direction of the ports. This configurability is available for the pure SDI products only. The alternative modes are: Input The plug is an input type Passthrough This option is valid for even numbered ports where the previous port (n-1) is an input port.

  • Page 50: Sdi - Input / Output Flow Configuration

    9.2 SDI - Input / Output flow configuration Once the port mode has been defined then the streams can be configured. Once the input ports are enabled the Thumbnail view will display the detected input and the status on the right-hand side of the main list view will present basic input analysis info. Enable Enable the input stream analysis.

  • Page 51: Ip-Gateway Setup With Sdi->Ip Flows

    9.3 IP-Gateway setup with SDI->IP flows Once the SDI input is configured correctly the SDI feeds can be mapped out of the unit as IP flows. To do this, go to the respective IP output location and select the RTP type sources. The ports configured as inputs will then be listed as valid sources. Please refer to the IP output application description for a more detailed explanation on how to do this.

  • Page 52: Expected Format

    Once selected the service will be routed from the input card to the SDI where the IP->SDI conversion will take place. Note the bitrate display in the flow view. In this example the SDI is taken from port 1 slot 14, sent out on the IP card in slot 4 port D1, returned back to slot 4/D2 then sent back to the SDI card in slot 14 out on port 5….

    9.5 SDI TICO UHD (2022-6) The TICO UHD encoder/Decoder is a unidirectional card. I.e. the flow direction is defined by the software image loaded to the card. Hence the flow direction we find in the SDI product has not meaning here. The UHD encoder encapsulates the SDI inti IP according to 2022-6.

  • Page 57: Tico Hd Encoder (2110)

    9.6 TICO HD Encoder (2110) The TICO HD encoder is quite different from the UHD by the fact that the HD signal is encapsulated into IP according to SMPTE 2110. This means each part of the SDI (the essences) is encapsulated into separate IP flows. This makes the configuration process of the IP flows different from the 2022-6 case.
