Compressed digital signal data selecting method for communication network, involves determining level of spatial granularity based on area interest and structure of data organization in signal to select data for each level

摘要

The method involves determining a level of spatial granularity based on an area of interest and a structure of data organization in a compressed data signal. The layer is determined based on a set of data necessary to satisfy a data transfer request and data received by a communication device e.g. client earlier. Data for each level of granularity is selected based on the area of interest and data organization structure. An Independent claim is also included for a device for data selection of a compressed digital signal.
