SMPTE RDD 22 – Film Transfer – 2048×1556 Image Container and Signal Interface

The intended application of this RDD is for the transfer of full frame film images to electronic media.

This RDD defines an image pixel array and interface container to transport a maximum pixel array of2048 x 1556, over a real time serial digital interface of 1650 lines. The source image is a 4:4:4 image,transported by a dual link interface.The 2048 x 1556 source image is mapped into 2 serial Interfacecontainers, 2 x 1536 x 778 pixels (dual channel) per link. The Y/G image samples are interleaved between theY and C channels of link A. The Red image samples are interleaved between the Y and C channels of link B.The Blue samples are interleaved between the C channels of link A and the Y channel of link B

This RDD serial interface data structure, sampling frequencies, and synchronizing signals have a lot incommon to other SMPTE defined HDTV Serial interfaces. These commonalities should allow for the use ofHDTV distribution equipment currently in use to transport these images. Because of the mapping format,processing and storage of the serial interface data will be required to display the 2048 x 1556 images.
