1. A method of video coding, comprising: transforming, with a video coding apparatus, a first block of residual pixel values of pictures by an integer transform function; generating, with the video coding apparatus, a corresponding second block of transform coefficients, wherein the integer transform function includes a vector set of eight vectors, said vector set is defined as: 0 ⁢ : [ 13 13 13 13 13 13 13 ⁢ 13 ] * n 1 ⁢ : [ 19 15 9 3 - 3 - 9 - 15 - 19 ] * n 2 ⁢ : [ 17 7 - 7 - 17 - 17 - 7 7 ⁢ 17 ] * n 3 ⁢ : [ 9 3 - 19 - 15 15 19 - 3 ⁢ - 9 ] * n 4 ⁢ : [ 13 - 13 - 13 13 13 - 13 - 13 ⁢ 13 ] * n 5 ⁢ : [ 15 - 19 - 3 9 - 9 3 19 - 15 ] * n 6 ⁢ : [ 7 - 17 17 - 7 - 7 17 - 17 ⁢ 7 ] * n 7 ⁢ : [ 3 - 9 15 - 19 19 - 15 9 ⁢ - 3 ] * n or 0 ⁢ : [ 169 169 169 169 169 169 169 169 ] * m 1 ⁢ : [ 247 195 117 39 - 39 - 117 - 195 - 247 ] * m 2 ⁢ : [ 221 91 - 91 - 221 - 221 - 91 91 221 ] * m 3 ⁢ : [ 183 - 59 - 243 - 135 135 243 59 - 183 ] * m 4 ⁢ : [ 169 - 169 - 169 169 169 - 169 - 169 169 ] * m 5 ⁢ : [ 135 - 243 59 183 - 183 - 59 243 - 135 ] * m 6 ⁢ : [ 91 - 221 221 - 91 - 91 221 - 221 91 ] * m 7 ⁢ : [ 39 - 117 195 - 247 247 - 195 117 - 39 ] * m where m and n are non-zero integer numbers.
