VIDEO RECONSTRUCTION FOR USE IN A CONSOLE-BASED RADIO COMMUNICATION

by Hans Christopher Sowa

SYSTEM BACKGROUND:

  The system is a console-based conventional or trunked radio system with portable and mobile radios. Radios in the system are not capable of sending any video information, but can send their location with the voice as embedded information.

THE PROBLEM:

  We would like to send video information back to the console so the console operator could see radio user. This is not possible since the system does not have any available bandwidth on the air to send video information. All of the existing bandwidth on the air is used up sending voice and some embedded information.

existing stored video ofthe user to appropriately move the user's face on the console's CRT The existing video data base would have recordings of various expressions ofthe user, i.e. anger, surprise, etc. Real time processing would be used to match the audio clues, such as pitch, level, rate, to existing video/audio to determine how to construct facial movements of the user.

  The background for the video of the user is tilled in using the embedded location information sent with the voice. Knowing the location of the user, another video data base is accessed to determine the correct background. This large database would contain video of all outside locations and some com- mon inside locations within range ofthe system.

  Using this above method, real time video of t...
