Method of controlling encoding of display data

A system comprising:

• a non-transitory memory storing instructions;
• and
• one or more hardware processors coupled to the non-transitory memory and configured to execute the instructions from the non-transitory memory to cause the system to perform operations comprising:
• performing at least a part of a first predetermined transform algorithm of a plurality of different transform algorithms on at least a first part of a first frame of display data;
• analyzing a light level of the first frame of display data to determine whether a different transform algorithm of the plurality of different transform algorithms 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 of the plurality of different transform algorithms would be more suitable for encoding, encoding the second part of the first frame of the display data using the different transform algorithm to generate an encoded first frame;
• and
• if it is determined that a different transform algorithm of the plurality of different transform algorithms would not be more suitable for encoding, encoding the second part of the first frame of the display data using the first predetermined transform algorithm to generate the encoded first frame.
