    4 REMOTE VIDEO WALL This chapter gives a quick introduction on how to use the Remote Video Wall feature of the VB7880 Advanced Content Extractor. 4.1 Introduction to the Remote Video Wall The VB7880 Advanced Content Extractor gives the opportunity to monitor the content of up to 64 multicast services or live OTT channel profiles spread across four web browser windows.

  • Page 19: Accessing The Remote Video Wall

    In addition the VB7880 Advanced Content Extractor can also be integrated with the VideoBRIDGE Controller enabling Network diagrams and alarm lists right next to crisp mosaics decoded from the selected streams. When VBC integration is available, any streams for which the VideoBRIDGE Controller has active alarms will be shown with a colored border in the RVW.

  • Page 20: Alarm View

    This widget makes it possible to display a list of active alarms, either from the VideoBRIDGE Controller or the VB7880 itself. The alarm source is can be configured for each widget instance. If VBC integration is disabled, the alarm source is ignored and the local alarms are always displayed.

  • Page 21: Image Viewer

    This widget displays a loudness graph for an audio channel of a multicast stream monitored on the VB7880 Advanced Content Extractor. Real-time audio analysis needs to be enabled for the stream for the data to be available. Up to two minutes of loudness data is displayed in the graph.
