scope:

The general guideline for transmitting large screen digital imagery (LSDI) programmes has been specified in [ITU-T J.601], and the network service operator's requirements for real-time transmission of expanded hierarchy of large screen digital imagery (exLSDI) signals under parallel processing functionality have been specified in [ITU-T J.602].

This Recommendation specifies the function components of a real-time transmission system for exLSDI signals compliant with [ITU-T J.601] and [ITU-T J.602] using spatial image segmentation for parallel processing. This system comprises of multiple video codec function units of any coding standards. The system also enables flexible adaptation to any image resolution available as an expanded hierarchy of LSDI.
