SYSTEM AND METHOD FOR TRANSFERRING IMAGES AMONG SPECTRUM AGILE RADIO DEVICES WITHOUT RETRANSMITTING IMAGES
First Claim
1. A system for transferring images among spectrum agile radio devices, comprising:
- a reasoner module for generating frame settings which are used to ensure that no two adjacent image pixels are placed in an identical frame which is to be transmitted;
an image description module operatively coupled to the reasoner module for storing image description data;
a transmission characteristics module operatively coupled to the reasoner module for providing parameters and environment characteristics in which the spectrum agile radio is located; and
a data link module operatively coupled to the reasoner module for storing data representing relationships between at least one of image parameters, transmission protocol and data link settings.

Abstract
A system and method for transferring images among spectrum agile radio devices without the need to retransmit image data. The system and method of the invention encodes and transmits packets so as to permit the efficient recovery of image data that is lost during transmission without the need to retransmit the packets. Instead of encoding packets containing adjacent pixels and transmitting them line-by-line, the system and method of the present invention encodes and transmits packets containing pixels from non-adjacent areas of a frame. As a result, any losses that occur within an individual packet are distributed throughout the image rather than in a specific line or isolated region of the image. This permits the efficient recovery of image data that is lost during transmission without the need to retransmit the data.

14. A method for transferring images among spectrum agile radio devices, comprising:
-
forwarding image description data which is stored in an image description module to a reasoner module; forwarding parameters and environment characteristics in which the spectrum agile radio is located from a transmission characteristics module to the reasoner module; forwarding data representing relationships between at least one of image parameters, transmission protocol and data link settings in a data link module to the reasoner module; generating frame settings in the reasoner based on the descriptions of images, the parameters and environment characteristics and the stored data; and encoding images based on the frame settings to ensure that no two adjacent image pixels are placed in an identical frame. - View Dependent Claims (15, 16, 18, 19, 20, 21, 22, 23, 24, 25, 26)
