Abstract: A depth image may be compressed and transmitted after being sampled to have less information before being coded, as opposed to a conventional scheme of compressing an original depth image. An uncompressed depth image of a non-transmitted depth image may be restored by sampling based on color information associated with a decoded color image and depth information associated with a decoded depth image. Thus, compression may be improved.

Abstract: A real-time stateful packet inspection method and apparatus is provided, which uses a session table processing method that can efficiently generate state information. In the apparatus, a session table stores session data of a packet received from an external network. A hash key generator hashes a parameter extracted from the received packet and generates a hash pointer of the session table corresponding to the packet. A session detection module searches the session table for a session corresponding to the received packet. A session management module performs management of the session table such as addition, deletion, and change of sessions of the session table. A packet inspection module generates state information corresponding to the received packet from both directionality information of the packet and entry header information of the packet stored in the session table and then inspects the packet based on the generated state information.
