Abstract: A system and method for transmitting video. Each frame of video is divided into a number of regions, that are transmitted in order beginning with a region of most importance. The region of most importance may be different from one frame to the next. When the video is transmitted over a channel with limited channel capacity, so that some frames are not transmitted completely, the region of most importance in a current frame may be selected to be the first region not transmitted in the previous frame. The system and method may be useful for the transmission of video data over a wireless link having variable or limited channel capacity.

Abstract: A method of stress compensation in a display device includes accumulating a brightness value of images displayed by the display device, encoding the accumulated brightness value to preserve a protected portion of the accumulated brightness value, compressing the accumulated brightness value, storing the compressed accumulated brightness value in a memory, retrieving and decompressing the compressed accumulated brightness value to generate a decompressed value, and decoding the decompressed value based on the protected portion to generate a decoded value corresponding to the accumulated brightness value, the decoded value having lower compression noise than the decompressed value.

Abstract: A system and method for operating a display. In some embodiments, the method includes: permuting elements of a stress profile for a slice of the display, with a first permutation, to form a permuted stress profile; compressing the permuted stress profile to form a compressed permuted stress profile; decompressing the compressed stress profile to form a decompressed permuted stress profile; and permuting elements of the decompressed permuted stress profile, with a second permutation, to form a decompressed stress profile, the second permutation being an inverse of the first permutation.

Abstract: A method of stress compensation in a display includes converting a stress profile for a slice of the display from a first format to a second format based on a conversion ratio; transforming the converted stress profile for the slice of the display, with a first transformation, to form a compressed transformed stress profile; decompressing the compressed transformed stress profile to form a decompressed transformed stress profile; and transforming the decompressed transformed stress profile, with a second transformation, to form a decompressed stress profile, the second transformation being an inverse of the first transformation.

Abstract: A system and method for operating a display. In some embodiments, the method includes: retrieving from a memory a first encoded stress profile and a first set of symbol statistics; processing, by a first decoder, the first encoded stress profile with the first set of symbol statistics, to form: a first decoded stress profile, and a second set of symbol statistics; augmenting the first decoded stress profile to form a second stress profile; processing, by an encoder, the second stress profile with the second set of symbol statistics to form a second encoded stress profile; and saving, in the memory, the second encoded stress profile.
