    摘要: A system and method for performing source buffering to transmit a real-time encoded scalable video to multiple transmission groups are provided. A streaming system for providing a scalable video bitstream for each multicast group may include an encoder source buffer to receive a scalable video bitstream and to store the received scalable video bitstream, and a plurality of subgroup transmitters, each to receive data of different layers in the stored scalable video bitstream from the encoder source buffer, to packetize the received data, and to transmit the packetized data to a terminal.

    摘要: A method of dividing a coverage area of a robot and a device for the same. That is, a method of producing a space map for a robot to work and dividing the space map into at least one segment and a device for the same. The method includes producing an occupancy grid map composed of grid points that are probabilistically distributed by sensing a distance from an obstacle, producing a configuration space map by increasing the thickness of an obstacle and a wall in the occupancy grid map on the basis of the radius and size of the robot, and dividing an area by sweeping the area with a band-typed slice in the configuration space map.

    摘要: Provided is a scalable video coding method and apparatus. Motion data of a high-quality fine grain scalability (FGS) layer is used for interlayer coding in order to remove redundancy between coarse grain scalability (CGS) layers or layers having different spatial resolutions, and information indicating that data of the FGS layer has been used for interlayer motion prediction is inserted for Moving Picture Expert Group (MPEG)-4 scalable video encoding. A bitstream extractor checks the information and performs extraction to maintain the data of the FGS layer. MPEG-4 scalable video decoding is performed using the information. By using the FGS layer, interlayer redundancy can be efficiently removed, thereby improving encoding efficiency.
