Internet protocol address to packet identifier mapping
First Claim
Patent Images
1. A method comprising:
- receiving information assigning an Internet protocol address to a first transport stream packet identifier, comprising;
receiving service identification information mapping a broadcast service component to a first transport stream identifier; and
receiving at least one announcement message mapping at least one Internet protocol address to a broadcast service component;
receiving a transport stream packet containing a second transport stream packet identifier;
determining by a demultiplexer whether the second transport stream packet identifier corresponds to the Internet protocol address; and
further processing the transport stream packet when the second transport packet identifier corresponds to the Internet protocol address.

Abstract
A digital video broadcast (DVB) receiver and methods are provided for processing Internet data. The DVB receiver receives at least one announcement message mapping an Internet protocol address to a transport stream packet identifier. Using the information, the DVB receiver may configure a demultiplexer to filter service components according to an Internet protocol address.

17. An apparatus comprising:
-
a demultiplexer configured to identify transport stream packet identifiers by receiving service identification information mapping a broadcast service component to a first transport stream identifier and receiving at least one announcement message mapping at least one Internet protocol address to a broadcast service component; a memory configured to contain an Internet protocol address and a corresponding transport stream packet identifier; and a processor programmed with computer-executable instructions to perform; receiving the identification of an Internet protocol address; retrieving from the memory the transport stream packet identifier corresponding to the Internet protocol address; and causing the demultiplexer to identify transport stream packets containing payloads addressed to the Internet protocol address. - View Dependent Claims (18)
