SMPTE Working Group H19.16 has proposed SMPTE Standard H19.161 defining the file format for the exchange of digital motion-picture information on a variety of media between computer-based systems. This flexible file format describes pixelbased (raster) images with attributes defined in the binary file descriptor, which identifies: generic file information, image information, data format, and image orientation information, motion-picture and television industry, specific information, user defined information. The draught assumes nonrealtime application, with formats for real-time to be considered as the developing technology permits.
