HD490 AFD Software 1 Introduction 1.1 System Overview The EEG HD490 AFD Software is a flexible and versatile module running on the HD490 Closed Caption Encoder that encodes and recovers Active Format Descriptors (SMPTE 2016-1-2007). The HD490 can be used to statically insert any legal AFD code on each video field in HD VANC,...
HD490 encoder to your local network. 2. Use the front panel LCD screen and button pad to set the HD490 IP address and subnet mask. These must be valid settings for your network, or you will not be able to communicate with the encoder.
3.2 Settings on the Configuration Panel The web-based configuration page controls the input and output behav- ior of the HD490 AFD tool. You must press the Apply button before any configuration changes take effect. You can press the Revert button at any time to before pressing Apply to cancel the changes that have not gone into effect yet.
3.2.3 Data Continuity VANC This field sets the number of frames that the HD490 will continue out- putting an AFD code from an upstream VANC source if that source stops sending AFD data. This feature can be used to ensure that AFD data will be encoded on every frame at the output even if an upstream source is only encoded on same frames.
HD490 AFD Software This field sets the number of frames that the HD490 will continue out- putting an AFD code from an upstream XDS source without seeing any new upstream XDS packets. This feature is critical for use of the XDS recovery feature because XDS cannot be sent on every frame due to Line 21 bandwidth limitations.
A Appendix A A.1 Network Automation Protocol HD490 software modules can be remotely controlled over a network by connecting to TCP port 2300 on the encoder. The messages sent to this port from any automation server must follow the format given in this appendix.
