IQOYA X/LINK range user manual Schematic diagram of IQOYA X/LINK-AES67 4.1.4 Audio inputs and outputs The audio inputs receive the audio signals to be encoded. They can be analog, or AES/3, or LAN audio (RAVENNA or AES67 or Livewire). Each source can be encoded several times at different formats, and streamed to several destinations. Audio samples decoded by X/LINK are played to the selected audio output.
Page 21: Ip Services
IQOYA X/LINK range user manual 4.1.6 IP services IP services are the way programs are streamed over the IP network. An IP service can include one audio program, or several multiplexed audio programs (case of MPEG-TS MPTS encapsulation). When IQOYA streams, an IP service can be sent to one IP destination (unicast or multicast), or several IP destinations (multi-unicast or multi-multicast).

Page 148: Appendix E: Available Fec's For Raw Rtp Streaming (No Ts Encapsulation)
IQOYA X/LINK range user manual 14. APPENDIX E: AVAILABLE FEC’ FOR RAW RTP STREAMING ( ENCAPSULATION FEC (Forward Error Correction) is a mechanism which consists in sending redundant information (redundant frames) to the decoder so that it can compensate packet transmission errors on unreliable networks. An FEC can be selected when defining the parameters of the stream to be generated (Send page) and/or to be received (Receive page).
Page 149 IQOYA X/LINK range user manual ● When in-band audio format signaling is disabled, it is possible to define the destination address and port of the FEC stream.
Page 150: Appendix F: Redundant Dual Streaming
IQOYA X/LINK range user manual 15. APPENDIX F: REDUNDANT DUAL STREAMING Spatial diversity IQOYA X/LINK can be configured to send the same AoIP stream on two distinct networks, typically through Eth0 and Eth1 interfaces. On the decoding side, IQOYA automatically synchronizes both received streams. Using separate network paths ensures that potential network failures are statistically uncorrelated, enabling the reconstruction of a unique unperturbed stream.
Page 151 IQOYA X/LINK range user manual ● When in-band audio format signaling is enabled, FEC stream is sent to the same IP address as the primary stream, and on UDP port + 2. ● When in-band audio format signaling is disabled, it is possible to define the destination address and port of the FEC stream.
Page 152: Appendix G: Mpeg-Ts Auxiliary Data
In raw mode, the packet only includes data coming from a serial port or from UDP (text, characters, commans). In Digigram mode, the packet can contain data coming from a serial port or from UDP (text, characters, commans), as well as triggers coming from physical or virtual GPI’s.
Page 153 IQOYA X/LINK range user manual 16. APPENDIX H: Modifying Maximum_Bitrate_Descriptor and ES_Rate_flag via the configuration file Since version 3.12, the MPEG-TS streams generated by IQOYA by default contain the descriptor “Maximum_Bitrate_Descriptor” in the PMT, and the ﬂag “ES_Rate_ﬂag'' in the PES. These ﬁelds are by default not present in the generated HLS streams.
