`represents the color image, a
`compression engine that compresses the
`color source image data to compressed
`image data, a means for encapsulating
`the compressed image data, and a means
`for transmitting the encapsulated data.
`The compression engine includes means
`for storing two quantization tables. The
`first quantization table is used to
`quantize the image data transformed
`using the discrete cosine transform
`(DCT). The second quantization table is
`encapsulated with the encoded
`quantized image data for use in
`decompressing the image. The second
`quantization table is related to the first
`quantization table in the manner
`described above. Whenusedto transmit
