<p>Provided are apparatuses and methods for transmitting and receiving timing information corresponding to updating parameters in an Electronic Service Guide (ESG) fragment. The parameters may be associated with a session of a program or service corresponding to the ESG fragment. In one example, the parameters may be updated and a timing information such as an RTP timestamp may be provided for indicating a time when the parameters may be loaded or implemented. In this example, when the RTP timestamp is greater than or equal to a timestamp of a data packet in a data stream, the time for the parameter change may have been achieved. At this time, the new or updated parameters may be loaded at a receiver.</p> |
