The invention discloses a method for transferring parameters of an internet protocol television (IPTV) service. The method comprises the following steps: obtaining parameters of the IPTV service and carrying out TV service operation according to the parameters. The invention also discloses a mobile IPTV user terminal, a time shift TV service control function and a metadata function. Since the session message carries the service parameters, for example, whether to support user control function, for a multicast service, if the network side doesn't support the user control function or doesn't allow the user to execute the user control function operation, the user control function operation is prohibited locally according to the obtained service parameters, thereby avoiding the unnecessary attempt. Therefore, the IPTV user equipment (UE) can prompt the user whether the current visit service support the user control via the interface.
