Abstract

Dynamically transforming transfer parameters for a media object to allow efficient transmission of the object from a first system to a second system. The transformer may receive transfer feedback and is configured such that it dynamically modifies system constraints or object formatting to overcome system limitations which may slow the transfer. The invention may be integrated into an internet service provider'"'"'s (ISP) system structure and used to dynamically determine the transfer parameters between the ISP and the end-user. After the ISP accesses a requested internet site and its web site server, a media object from the web site is transferred to the ISP. The ISP transfers the information to the end-user and, during the transfer, receives system feedback regarding bandwidth availability, performance, information latency, and other items of interest. Using this feedback, transfer parameters are automatically selected to increase efficiency of system resources for subsequent media transfers. Transfer parameters may alternatively be anchored by the ISP or the end-user to prevent dynamic modification.
