The multiple component transformations are then applied to each component collection independently. Optionally, the frames can be grouped into one or more component collections. After the multiple component transformation has been applied, the transformed frames are encoded using the process described in JPEG 2000 Part 1.
If the object allows multi-frame images in the pixel data field, then, for these JPEG 2000 Part 2 Transfer Syntaxes, the frames in the object are first processed using the multi-component transformation. The only wavelet transformations that are allowed to be used as multiple component transformations are the reversible 5-3 wavelet transformation and the irreversible 9-7 wavelet transformation, as defined in Annex F of JPEG 2000 Part 1 ( ). The arbitrary wavelet transformations, as defined in Annex H of JPEG 2000 Part 2 ( ) are not allowed for these two Transfer Syntaxes.
Additional features and extensions that may be defined in other Annexes of JPEG 2000 Part 2 shall not be included in the compressed bitstream. Only the multiple component transformation extensions defined in Annex J of JPEG 2000 Part 2 ( ) are permitted for these two Transfer Syntaxes.
