1. A method comprising:
obtaining a video stream;
decoding a value from the video stream; and
decoding the video stream via circuitry which uses the value to decode the video stream, the value being a numeric encoding of an encoding level to which the video stream conforms,
wherein the encoding level is represented in a form majorNum.minorNum, and the value is a sum of majorNum multiplied by a first constant added to the minorNum multiplied by a second constant.
