Disclosed are a system and a method that generates image data that represent a speaker to be distinguished, and enables a mobile terminal to provide a video conference service using the image data that distinguishes the speaker. A video conference apparatus may include a speaker distinguishing unit to distinguish, as a speaker, a participant who is speaking from a plurality of participants in the video conference and an image data generating unit to generate image data that represents the distinguished participant differently from other participants.

Provided is a network synchronization method and apparatus for performing a time synchronization between nodes. When a system starts up and the time synchronization between the nodes is initiated, the network synchronization method and apparatus may enhance jitter, wander, and a time synchronization performance by gradually increasing a window size for a propagation time measurement. When a full window of propagation time measurements is collected, the network synchronization method and apparatus may enhance jitter, wander, and the time synchronization performance by applying an exponential to a computation of an average propagation time value.

Disclosed is an apparatus for monitoring an optical signal-to-noise ratio in a WDM optical network. The apparatus includes an orthogonal polarization component module for receiving an optical signal and outputting it after removing a signal component thereof at a specific frequency band; and calculation means for measuring both average signal and noise component intensity of the optical signal outputted from the orthogonal polarization component module. By removing a signal component at a specific frequency bandwidth and passing only a noise component through, it is possible to easily measure the noise intensity within a signal bandwidth that cannot be measured in general. A frequency band is set within a signal bandwidth, and the signal intensity is minimized at the set frequency band, so that it is possible to measure the optical signal-to-noise ratio even for a signal whose amplified spontaneous emission noise spectrum is not flat, irrespective of the signal pattern length.

A depth information measuring method and apparatus for a three-dimensional (3D) camera may output, to an object, an optical pulse of which an intensity is higher than an intensity of an ambient light. The depth information measuring method and apparatus may generate a voltage that is proportional to a log value of an intensity of a light reflected from the object. The depth information measuring method and apparatus may use discharging units, and the discharging units may respectively include dischargers having different discharging speeds or capacitors having different capacities.

An apparatus and a method for transmitting and receiving a spike event in a neuromorphic chip. A transmission apparatus of the neuromorphic chip outputs addresses sequentially and repeatedly to an address bus, and when a spike generated by a neuron is detected by the transmission apparatus, outputs a strobe at a first time when one of the addresses being output sequentially and repeatedly becomes identical to an address of the neuron that generated the spike. A receiving apparatus of the neuromorphic chip inputs an address through the address bus at a strobe detection time when the strobe is detected by the receiving apparatus.
