Enhanced method for controlling network devices in a very low power consumption state

摘要

The present invention relates to a method for controlling network devices in a low power consumption state, comprising the steps of: generating a network packet to be transmitted over a network to the network devices, the network packet containing at least a data portion, wherein said data portion comprises a preamble portion, and a sequence of n identical hardware multicast or broadcast address portions. The invention also relates to a method for controlling network devices in a very low power consumption state, comprising the steps of: generating a network packet to be transmitted over a network to the network devices, the network packet containing at least a data portion, wherein said data portion comprises a preamble portion, a sequence of n identical hardware unicast address portions, a password portion and a network and/or device address portion.

1. A method for controlling a media output device, the method comprising:
generating, by circuitry, a network packet including a data portion, the data portion including
a sequence of n identical hardware multicast or broadcast address portions that follows a preamble portion, each of the n identical hardware multicast or broadcast address portions is the network address of the media output device,a password portion that follows the sequence of n identical hardware multicast or broadcast address portions,an origin address portion that follows the password portion and that includes a network address of the circuitry, anda control tag portion; transmitting, by the circuitry, the network packet to the media output device over a local area network (LAN) that is separate from an audio/video data channel to the media output device; receiving, by the media output device, the network packet; comparing, by the media output device, the password portion and the origin address portion of the network address packet with predetermined values stored in the media output device; and performing, by the media output device when the password portion and the origin address portion of the network packet match the predetermined values, one or more functions in response to a control tag in the control tag portion of the network packet.
