Systems and methods of encoding display data include performing a part of a first predetermined transform algorithm on at least a first part of a first frame of display data, and analyzing a light level to determine whether a different transform algorithm would be more suitable for encoding a second part of the first frame of the display data. If it is determined that a different transform algorithm would be more suitable for encoding, the second part of the first frame of the display data is encoded using the different transform algorithm to generate an encoded first frame. If it is determined that a different transform algorithm would not be more suitable for encoding, the second part of the first frame of the display data is encoded using the first predetermined transform algorithm to generate the encoded first frame.

Method of controlling encoding of display data

Methods and systems for encoding display data by performing at least a part of a first predetermined transform algorithm on at least a first part of a first frame of display data to generate a first set of transform coefficients, and analysing information relating to at least the first set of transform coefficients to determine whether a different transform algorithm would be more suitable for encoding a second part of the first frame and/or a subsequent frame of the display data. If a different transform algorithm would be more suitable for encoding, the second part of the first frame and/or subsequent frame is encoded using the different transform algorithm to generate an encoded first frame and/or subsequent frame. If a different transform algorithm would not be more suitable, the second part of the first frame and/or subsequent frame of the display data is encoded using the first predetermined transform algorithm.
