PID FILTER BASED NETWORK ROUTING

摘要

A television Set-top box based content server (104) consistent with certain embodiments of the present invention has a receiver (116, 120) that receives a transport stream containing data representing content in packets, wherein the packets are identified by packet identifiers (PIDs). A PID filter (124) selects packets having a specified PID. A mapper (150) maps packets having the specified PID to an Internet Protocol (IP) address. The mapper uses the PID as an index to a translation table (204) and retrieves the IP address from the translation table (204). A packet converter converts the packets identified by the specified PID to an IP packet having the IP address. A router (160), such as a wireless ultra- wideband router, routes the IP packet to a recipient according to the IP address.
