Abstract

A method and apparatus for tuning to a channel of a Moving Pictures Expert Group transport stream (MPEG-TS), for example used in an Internet Protocol Television (IPTV) network, are provided for optimising a channel change procedure. The method comprises the steps of receiving a MPEG transport stream at a first bit rate, the MPEG transport stream comprising a plurality of television channels. Program clock reference (PCR) values are identified in the received MPEG transport stream, and one or more of the program clock reference (PCR) values are adjusted. The MPEG transport stream, including the adjusted program clock reference values, are transmitted at a second bit rate, for example to a receiver device such as a set top box, thereby enabling the set top box to perform a channel change procedure more quickly.
