1. A motion vector compression method, comprising:
obtaining an 18 bit temporal motion vector;
determining a compressed motion vector using a binary representation of at least one of the 18 bit temporal motion vector, a binary representation of the compressed motion vector comprising an exponent part or a mantissa part, wherein the exponent part comprises N bits, the mantissa part comprises M bits, and wherein N is a non-negative integer and M is a positive integer, wherein the representation of the compressed motion vector is 10 bits; and
performing a temporal motion vector prediction (TMVP) using the compressed motion vector.
