Abstract
Methods and apparatus for processing and using TCP packets to communicate RTP packets are described. Head of line blocking is avoided by operating a TCP packet processing module to output RTP packet data to an application irrespective of whether or not a preceding TCP packet was received. Since output of packet data to an application using RTP packets is not delayed when there is a missing TCP packet, head of line blocking is avoided. RTP packet data is subjected to pattern matching in order to identify and process RTP packets in the case where RTP header information such as packet length information is missing due to the failure to receive a TCP packet. The methods are particularly well suited for the communication of audio and/or video by devices operating behind firewalls which block UDP or other types of packets other than TCP packets.
