IMA ADPCM
IMA ADPCM – The IMA has selected the 4:1 ADPCM audio compression scheme from Intel’s DVI as the preferred compressed audio date type for interactive media platforms. Intel had offered the algorithm as an open standard to the IMA. The algorithm compresses 16-bit audio data at up to 44.1 kHz sampling into 4-bit ADPCM words. Image – A two dimensional (usually) picture. The picture may be represented in digital form or mathematically as an image is a set of planes in two dimensions. The two dimensions are the resolution in X and Y (columns, lines). The origin (0, 0) of the image is sometimes its lower left corner. There are four basic types of images: black & white or color, mask or no mask, Z plane or no Z plane, IPR information or no IPR information.
