Abstract: A remote controller applied to a display device includes a wireless communication element, a voice receiving and transmitting element and a control unit. The wireless communication element is utilized for performing a wireless communication with a set-up box of the display device. The control unit is coupled to the wireless communication element and the voice receiving and transmitting element, and is utilized for controlling a voice communication between the wireless communication element and the set-up box. When the remote controller does not need to have the voice communication and any other communication with the set-up box, the control unit disables the wireless communication element to make the wireless communication element be unable to receive and process any information from the set-up box.

Abstract: The present invention provides a TV box, where the TV box is connected to a display via lined connection or wireless connection, and the TV box includes a control unit, a network interface circuit and an output unit. The control unit connects to a first external server and an audio/video source via the network interface circuit, the control unit obtains a channel list from the first external server, and obtain audio/video information from the audio/video source by referring to a user inputted command and the channel list, where contents of the channel list is allowed to be edited by a user, and the control unit transmits the audio/video information to the display via the output unit.

Abstract: A multiparty communication management method employs an initiative computer device to initiate a multiparty communication for connecting to plural receiving communication devices. Next, any receiving communication devices is employed to call an initiative communication device via the user interface or DTMF, whereby the initiative communication device is joined the multiparty lines communication. Finally, the initiative computer device can directly control the voice signals of any of receiving communication devices. By aforementioned method, conferees of the multiparty communication can request the initiator to manage the communication instead of redundant commands required in the art, thereby providing a multiparty communication management method with higher operation rate and greater convenience.
