(54)	System and method for using pattern vectors for video and image coding and decoding

(57) A method for use in a decoder, the method comprising:
receiving, in a bitstream, a bit vector, for which bit vector a respective position is associated with a corresponding transform coefficient according to an ordered scan of a block of transform coefficients, wherein the respective position in the bit vector has a 1 to indicate a non-zero transform coefficient in a corresponding position in the ordered scan and a 0 to indicate a zero transform coefficient in a corresponding position in the ordered scan; and
identifying, based on the bit vector, at least one non-zero transform coefficient.
