Abstract: An image signal processor includes a statistic data generating unit for receiving an image signal from an external device, an image processing unit for receiving the image signal, and a direct memory access (DMA) module connected to the statistic data generating unit and the image processing unit. The statistic data generating unit performs first image pre-processing on the image signal and generates first statistic data based on the image signal subjected to the first image pre-processing. The DMA module stores the first statistic data therein and provides the stored first statistic data to the image processing unit. The image processing unit performs second image pre-processing on the image signal and performs image processing on the image signal based on the first statistic data.

Abstract: A peer-to-peer (P2P) streaming apparatus includes a P2P logic unit positioned at a demarcation point between a private network and a public network and performing P2P communication for sharing a multimedia stream with another user; and a delivery unit delivering the multimedia stream to an internal user terminal within the private network.
