Abstract
A television Set-top box based content server consistent with certain embodiments of the present invention has a receiver that receives a transport stream containing data representing content in packets, wherein the packets are identified by packet identifiers (PIDs). A PID filter selects packets having a specified PID. A mapper maps packets having the specified PID to an Internet Protocol (IP) address. The mapper uses the PID as an index to a translation table and retrieves the IP address from the translation table. A packet converter converts the packets identified by the specified PID to an IP packet having the IP address. A router, such as a wireless ultra-wideband router, routes the IP packet to a recipient according to the IP address.
Claims24
A method of processing data packets, comprising:
- receiving a transport stream containing a packet of data identified by a program identifier (PID);
- mapping the PID to an Internet Protocol (IP) address;
- and
- converting the packet to an IP packet containing the data and having the IP address.
A content server, comprising:
- a receiver that receives a transport stream containing data representing content in packets, wherein the packets are identified by packet identifiers (PIDs);
- a PID filter that selects packets having a specified PID;
- a mapper that maps packets having the specified PID to an Internet Protocol (IP) address;
- and
- a packet converter that converts the packets identified by the specified PID to an IP packet having the IP address.
A television Set-top box based content server, comprising:
- a receiver that receives a transport stream containing data representing content in packets, wherein the packets are identified by packet identifiers (PIDs);
- a PID filter that selects packets having a specified PID, wherein the packet contains at least one of video and audio content;
- a mapper that maps packets having the specified PID to an Internet Protocol (IP) address, wherein the mapper uses the PID as an index to a translation table and retrieves the IP address from the translation table;
- a packet converter that converts the packets identified by the specified PID to an IP packet having the IP address;
- and
- a router that routes the IP packet to a recipient according to the IP address.
