PGVV is apparently a video codec generated by a piece of software named Radius Studio. A search revealed that it might be "Radius VideoVision Telecast" and using "adaptive JPEG". The claim that it is JPEG should be right as some products claim they can convert losslessly to [[MJPEG-B]].
PGVV is apparently a video codec generated by either the Video Vision hardware grabber card, or with the Radius Studio software. All the brochures and reviews say that it is using an "adaptive JPEG", which can have variable bitrate. There are some lossless conversion utilities to MJPEG-B, thus it should be very similar to standard JPEG.

PGVV is apparently a video codec generated by either the Video Vision hardware grabber card, or with the Radius Studio software. All the brochures and reviews say that it is using an "adaptive JPEG", which can have variable bitrate. There are some lossless conversion utilities to MJPEG-B, thus it should be very similar to standard JPEG.
