Abstract: The present disclosure provides a magnetron sputtering apparatus, including a process chamber, a bias power supply assembly, and an excitation power supply assembly. The process chamber is provided with a base assembly and a bias guide assembly. A target is arranged at a top of the process chamber. The base assembly is arranged at a bottom of the process chamber and is configured to support a wafer carrier, drive the wafer carrier to move, and heat the wafer carrier. The bias guide assembly is arranged at the base assembly and configured to support the wafer carrier. The bias guide assembly is electrically in contact with the wafer carrier. The bias power supply assembly is electrically connected to the bias guide assembly and configured to apply a bias voltage to the wafer carrier through the bias guide assembly.

Abstract: A media type processing method and apparatus, a media playing method and an EPG subsystem in an IPTV system are provided. The processing method and the media playing method comprise: defining a media type set; an SMS subsystem mapping all media types supported by programs or channels into the media type set, and issuing to an EPG subsystem; mapping the media types supported by a terminal as the media type set; after the authentication is passed, the SMS subsystem returning the media type set supported by the terminal to the EPG subsystem; and after the EPG subsystem receives a media playing request from the terminal, judging whether the media type set supported by the terminal is matched with the media type set supported by the programs or channels, and if being matched, acquiring information about the playable physical program from a database and issuing to the terminal for playing.
