Patent ID: 8451904

Claim:
A method comprising: receiving media data with a coding device, wherein the media data comprises one or more of audio, video or image; and performing a 8-point discrete cosine transform (DCT) with an 8-point DCT hardware unit of the coding device to transform the received media data from a spatial domain to a frequency domain, wherein the 8-point DCT hardware unit includes: an even portion comprising first and second internal factors (A, B) that are related to a first scaled factor (μ) in accordance with a first relationship, wherein the first relationship is defined such that the first scaled factor equals a square root of a sum of a square of the first internal factor plus a square of the second internal factor; and an odd portion comprising third, fourth, fifth and sixth internal factors (G, D, E, Z) that are related to a second scaled factor (η) in accordance with a second relationship, wherein the second relationship is defined such that the second scaled factor equals a square root of a sum of a square of the third internal factor plus a square of the fourth internal factor, and wherein the second relationship also is defined such that the second scaled factor equals a square root of a sum of a square of the fifth internal factor plus a square of the sixth internal factor.
