An apparatus and method are provided for allowing UPnP devices to exchange power mode information with one another in a unified home network. The method of relaying a message in a unified network including at least first and second networks, the method includes receiving information regarding a power mode of a communication device connected to the first network from the communication device, generating a message indicating the power mode of the communication device based on the received information, and transmitting the message to the second network so that communication devices connected to the second network recognize the power mode of the communication device connected to the first network. Accordingly, even if a UPnP device in the power save mode cannot receive or transmit messages, another UPnP device can determine whether the UPnP device is connected to a network. If a new UPnP device generates an IP address according to an automatic IP mechanism, it is possible to prevent IP collision caused by a UPnP device that is connected to an IP network but operating in the power save mode.

A system and method for establishing a secured connection between home network devices are provided. Particularly, a system and method for establishing a secured connection between a home network including a plurality of non-secured Universal Plug and Play (UPnP) devices and a secured external UPnP device by creating virtual UPnP devices for the respective corresponding non-secured UPnP devices are provided. The system for establishing a secured connection between home network devices includes a virtual UPnP device creation unit which creates a secured virtual UPnP device for a non-secured UPnP device, an information storage unit which stores correspondence information regarding the non-secured UPnP device and the virtual UPnP device, and a secured communication unit which securely communicates with a secured UPnP device with reference to the correspondence information.

Provided are a system in package (SIP) semiconductor device suitable for efficient power management, and a method of managing power of the SIP semiconductor device. The SIP semiconductor device includes chips including first and second chips. Each of the chips includes an alive block, a local interface, and an intellectual property (IP) block. The alive block is continuously supplied with power in order to continuously be in an on-state. The local interface transmits/receives data to/from other chips. The IP block individually stores and processes data. The alive blocks of the chips are connected to each other through a first signal line unit for transmitting a signal required to wake up or initialize the chips. The alive blocks control power to the chips, respectively, in response to an external wake-up instruction signal or the signal transmitted through the first signal line unit. Therefore, power can be efficiently managed since power that is supplied to the chips of the SIP semiconductor device is managed by the alive blocks or the local interfaces of the chips.

An interface device transforms data to a packet and inverts at least a portion of the packet to reduce a number of bit toggles at corresponding locations in a previous packet. A reverse bit appended to the packet indicates whether the packet is inverted. A transmission packet including the reverse bit and the portion of the packet inverted according to a state of the reverse bit is transmitted, and the data are recovered from a received packet, the portion of which that was inverted is inverted again according to the state of the reverse bit.

A data recovery circuit and a method thereof, which are capable of reducing locking time and jitter, are provided. The data recovery circuit includes a frequency-locked loop, a locking detector, a delay-locked loop, and a data determination circuit. The frequency-locked loop locks the frequency of an internal clock signal fed back thereto in response to an input signal with the frequency of the input signal and generates a frequency locking signal representing that the input signal is frequency-locked with the internal clock signal. The locking detector determines whether the frequency of the internal clock signal is in a predetermined frequency range of the input signal in response to the frequency locking signal and generates a phase control signal. The delay-locked loop is controlled by the phase control signal, locks the phase of the internal clock signal with the phase of the input signal, and generates a recovery locking signal. The data determination circuit receives the recovery locking signal as a clock signal, receives the input signal in response to the clock signal, and outputs the input signal as output data.
