Method and device for image and video transmission over low-bandwidth and high-latency transmission channels

A method for transmission of images and/or video over bandwidth limited transmission channels having varying available bandwidth, the method comprising the use of a classification algorithm for

• decomposing the images and/or video to be transmitted into multiple spatial areas, each area having a specific image type;
• detecting the image type of each of those areas
• separately selecting for each of those areas an image and/or video encoding algorithm having a compression ratio;
• wherein said classification algorithm prioritizes each of said areas, said classification algorithm increasing the compression ratio of the image and/or video encoding algorithm dedicated to spatial areas having lower priority in case of decreasing bandwidth.

A method for transmission of images and/or video over a transmission channel from a server to a client, the method comprising the steps of

• decomposing the images and/or video to be transmitted into multiple spatial areas, each area having a specific image type;
• detecting the image type of each of those areas;
• separately selecting for each of those areas an image and/or video encoding algorithm using a code for encoding said images and/or video of said area;
• wherein said client is a reconfigurable device, said method further comprising the step of reconfiguring said reconfigurable device for decoding said images and/or video of said areas.
