Method and system for delivery of coded information streams, related network and computer program product therefor

摘要

A method of controlling operation of a network wherein at least one coded information stream (I') is delivered to at least one user via at least one link (20, 40) exposed to variable operating conditions, the method including the steps of: monitoring the operating conditions of the at least one link (20, 40), and selectively transcoding the at least one coded information stream (I') by selectively varying at least one transcoding parameter (Q) as a function of the operating conditions monitored. The monitoring operating conditions of the at least one link includes evaluating a set of cost functions (QUANTIZATION_COST, MOTION_COST, DETAILS_COST) related to an available bit rate (R) and to complexity of said coded information stream (I') and €ƒ€ƒ
