| The VRC-100 VANC Receiver Card provides a simple and highly configurable way of monitoring the VANC data in a SMPTE 292M signal. Information about the VANC content is displayed over the video that contains it. The user has complete control over the data that is decoded and how it is displayed. The card is capable of eight screen overlay layouts controllable by GPI (switches) or the overlays may be switched automatically on a timed basis. The card detects the presence of the data, whether it is correctly coded and can display the details of the data in readable form. Alarms in the user interface are triggered if data is not correct or not present . Alarms may be displayed as part of the overlay or may be tied to GPIOs.
The VRC-100 can monitor the following VANC data types:
Captioning, CEA-708 including embedded CEA-608
Active Format Description (AFD), SMPTE 2016
Audio Metadata, SMPTE 2020 method A & B
Time-code SMPTE 12M-2
Text Tags, video source identifiers
Redistribution Control (broadcast) Flag, SMPTE RP207
Detection of generic data based on DID and SDID
A map showing the contents of the VANC space
The concept of the VRC-100 is your data your way. Watch your video and overlay as much information about the VANC as you wish to see. Perhaps you want just presence indicators to cover as little video real estate as possible but, at the flip of a switch, you can drill down to all the details of the caption data. In a post production environment you can see your video with time-code and check that the data you are adding is present and correct. On ingest, you can see a map of all the data in the VANC and then drill down to see if it is coded correctly.
The VRC-100 offers a complete user interface through DashboardT, the free Java-based application that provides a common control and monitoring interface for multiple openGear frames and cards. The interface allows the construction of up to eight screen layouts containing the data display components from a large library of choices. A typical VANC data type will have a presence indicator, a short form decoded description and a detailed description allowing maximum flexibility in creation of overlay screens. To simplify workflow the VRC-100 automatically adapts to the incoming HD video. Your layouts are stored in flash on the card and may be selected using GPI (switch) inputs, through the Dashboard interface or cycled in timed fashion. Loss of data or data content problems can be monitored on screen, in Dashboard or tied to GPIOs for external signaling.
Eight screen overlay layouts of VANC data contained within a SMPTE 292 signal:
Closed-captions
Audio Metadata
AFD
Time-code
Broadcast Flag
Triggers
User-defined Data
The VRC-100 helps solve challenges such as:
Closed-caption compliance monitoring
Monitoring VANC data at ingest
Confidence checking data insertion
Trigger and text tag verification
