Abstract: A signal processing apparatus which processes a voice packet is provided. The signal processing apparatus includes: a network jitter measurer which estimates network jitter using a weighting of a network jitter variance according to a network state, a compression and output unit which compresses or outputs a voice frame based on the estimated network jitter, and a loss concealer which divides a voice packet loss into short-term loss concealment and long-term loss concealment, and performs loss concealment in a different way depending on whether the voice packet loss is the short-term loss concealment or the long-term loss concealment.

Abstract: A method and apparatus for providing a three-dimensional (3D) image is provided. In the method, first-viewpoint image data and second-viewpoint image data that provide a 3D image are obtained. Time information that represents points of time that the first-viewpoint image data and the second-viewpoint image data are to be processed is produced, based on relation information to indicate that the first-viewpoint image data and the second-viewpoint image data are a pair of pieces of image data. The first-viewpoint image data, the second-viewpoint image data, and the time information are transmitted. The first-viewpoint image data is transmitted in a first stream, and the second-viewpoint image data is transmitted in a second stream.
