![]() The "session" information is in the framing, the image information is in the payload. This allows for the separation of a "session" (consisting of a sending station sending one or more images) from the minimal content required for a single image. Framing is independent of the specification. It can be used in any packet protocol or digital mode. The PDP spec merely defines the packet payload for transmission of a single image. Some unique features enabled by PDP are given in this page. ![]() This allows images to be restored using compressed sensing techniques regardless of packet loss. Unlike other packetized transmission formats, the pixels contained in a packet are selected in a pseudorandom, yet deterministic, way. An image is then transmitted as the collection of datagrams. ![]() PDP is a specification for the payloads of data packets such that each packet contains all the information needed to reconstruct a single image.
