Abstract: A method of rate control of a display device includes receiving compressed stress data for a slice of a display, decompressing the compressed stress data to obtain reconstructed stress data for the slice, adding additional stress data to the reconstructed stress data to obtain updated stress data for the slice, encoding the updated stress data at a first precision level (pc) to generate first updated compressed stress data for the slice, in response to a size (bc) of the first updated compressed stress data for the slice of the display exceeding a size (bt) of a buffer, determining a second precision level (p) based on the first precision level (pc), a third precision level (ps) of the additional stress data, and a fourth precision level (pb) of the buffer, and encoding the updated stress data at the second precision level (p) to generate second updated compressed stress data.

Abstract: A system and method for compressing video data. When a triplet of data values corresponding to a pixel differs sufficiently little from a previous, reference triplet, the difference is encoded using one of several encoding functions selected according to which of several criteria of similarity between the current triplet and the reference triplet is met. When none of the available criteria of similarity is met, the triplet is instead encoded using differential pulse code modulation with non-uniform quantization.

Abstract: A system and method for transmitting compressed video. A transmitter receives uncompressed video data from a video source, and compresses it using one or more reference frames. A receiver receives the compressed video data and decodes it, using the same reference frames, to form display data. The reference frames are stored in compressed form in both the transmitter and the receiver. Each frame of display data becomes a reference frame for the decoding of a subsequent frame.

Abstract: A method of stress compensation in a display device includes retrieving, by a decoder, compressed stress data that is quantized by a quantization value, decoding, by the decoder, the compressed stress data to generate decoded data, generating a dither value based on the quantization value, and adding the dither value to the decoded data to compensate for quantization of the compressed stress data.

Abstract: A system and method for image testing is configured to apply at least one display property to a test image to generate a display modified test image and applying the at least one display property to a reference image to generate a display modified reference image. The system also applies a human eye model to the display modified test image to generate an eye modified test image and applies the human eye model to the display modified reference image to generate an eye modified reference image. The system may compare the eye modified test image with the eye modified reference image to determine human perceivable differences between the test image and the reference image.
