VRSG Real-time Video Recording

Back to VRSG Dashboard Interface      

On the Record tab of the VRSG Dashboard you can record video of VRSG-generated scenes in either MPEG or AVI format:

• MPEG output (MPEG-2 or H.264/MPEG-4) can be recorded at nearly any resolution of your choice (set in the Preferences tab) at 30 or 60 Hz, and can be directed to local directory on your machine, or streamed to a network address using the User Datagram Protocol (UDP). The output supports the KLV encoding of UAV telemetry in a compliant subset of NATO standard STANAG 4096 to include EG 0601 KLV metadata, and MISB security metadata standard 0102.7.
  
  
• AVI output can be recorded at 640 x 480 resolution or 720 x 480 at 30 Hz to a directory on your machine. This uncompressed AVI video option yields the highest possible quality recording and is useful for cases in which video authoring is your primary objective.

Using VRSG's recording feature, MetaVR has made several real-time recordings of scenarios rendered in VRSG. The scenarios feature 3D databases built by MetaVR and entities from MetaVR's 3D content libraries.

Tactical exploitation systems can use the streaming MPEG feed to visualize sensor payload imagery in real time and extract the UAV metadata. On the Record tab are options to record UAV KLV metadata multiplexed into an MPEG2 transport stream. When one of the two UAV telemetry encoding options is selected, VRSG generates an MPEG-2 or H.264 transport stream with two embedded streams: one for video and another for the selected KLV metadata. The GV 3.0 viewer and metadata editor, a GOTS tool, is one system that can play the MPEG stream and decode the KLV metadata. To simply view the recorded video (without decoded metadata), you can use MPEG players such as QuickTime or VLC.

Some networked environments do not have the bandwidth to handle VRSG's streaming MPEG directly. In such a case, a site can set up a UAV regeneration station to capture the streaming MPEG of the VRSG-simulated UAV camera payload video in the form of data packets. The packets are then regenerated as video, and streamed to another device on a local network, such as a ROVER. This regeneration station is a computer with another VRSG license that can receive UAV Master messages over a long-haul network from a remotely located UAV operator. The local receiving device can be a ROVER device or any device that can play back video from an ISR video feed.
