Sleeping device(s) may be changed from a sleeping state to an awake state using a multicast packet that sent to a multicast address of a multicast wake-up group. The packet may include an identifier for one or more particular device(s) in the multicast group, which, when received by the device(s), causes the device(s) to wake up.

A mobile terminal for performing operations with respect to broadcast content includes a controller capable of operating a client application. The client application can perform operations including operating in a recording mode. In the recording mode, the client application can record content for a selected channel, and store the recorded channel in a database. In response to changing channels from the selected channel to another channel, the client application can initiate a recording timeout for the selected channel. The client application can reset the recording timeout for the selected channel for each subsequent instance of changing channels back to the selected channel. If the recording timeout expires before being reset for a subsequent instance of changing channels back to the selected channel, however, the client application can cease recording content for the selected channel.

The number of power-gating transistors on an integrated circuit used for power reduction in a sleep mode is controlled during a wake state to adjust the current flow and hence voltage drop across the power-gating transistors as a function of aging of these transistors and/or a function of temperature of the integrated circuit. In this way, the supply voltage to the integrated circuit may be better tailored to minimize current leakage when the integrated circuit is young or operating at low temperatures.

When chip is in stand by mode, system operation timer of the chip is closed so that each module in the chip stops working.
