Abstract:
PURPOSE: A gateway between different kinds of networks for the improvement of communication speed and a method for allocating resources thereby are provided to offer an automatic bandwidth control method for an Internet traffic change in a communication processing system to continually supply virtual access service to Internet service providers on the basis of frame transmission, in the case of providing connection-oriented service in a communication system. CONSTITUTION: If data are inputted to a link layer drive task queue and setup for a subscriber's input call is completed, a link layer drive task determines a link control routine(ToLCP) or a frame receiving routine(CMD_FRM_RCVD). If a PPP command is CMD_FRM_SND to transmit Ack/Nak/Reject packets or IP packets to an LLD, the link layer drive task negotiates a logical channel with a WNAS while monitoring Internet traffics, and transmits frames to an associated channel(SendToPort). Then the link layer drive task calls a data transmitting routine in order to transmit data to an internal switch(SendDataToNCCB), determines a PPP frame or an MP frame to send data, and executes a data transmit-receive process for a basic channel.

Abstract:
The present invention relates to a method and an apparatus for generating a multi-view image based on shielded area information. The method for generating a multi-view image, according to the present invention, comprises the steps of: calculating a variation between the left and right images; determining a weight based on the variation information; and generating a virtual viewpoint image by applying the weight.
Abstract:
A method and an apparatus for decoder buffering in a video system using two types of codec are disclosed. A transmitting device of the video system using two types of codec includes: a first video encoder which encodes a first video using a first video codec; a second video encoder which encodes a second video using a second video codec; and a delay buffer which synchronizes a delay time for the first video with a delay time for the second video, based on the buffer size of a first transport-stream system target decoder (T-STD) defined by the first video encoder and the buffer size of a second T-STD defined by the second video encoder.

PURPOSE: A method of extracting a salient region and an apparatus using the same are provided to detect a salient region in a scene for maintenance of depth perception when generating a multi-view image, thereby improving depth perception of a stereo image. CONSTITUTION: A method of extracting a salient region by a salient region determining apparatus comprises the steps of: segmenting a stereo image(S130); producing a sparse disparity(S150); producing an average disparity of each segment(S160); normalizing and storing the average disparity of each segment(S165); producing an average motion of each segment(S170); and producing a saliency of each segment(S180). [Reference numerals] (AA) Input right and left stereo images; (S100) Extract a salient region and calculate variation between salient regions; (S110) Calculate illumination-based low-resolution stereo image variation; (S120) Calculate the movement between frames for each right and left image; (S130) Divide a stereo image and extract a segment; (S140) Combine variations; (S145) Remove an outlier; (S150) Calculate and store a sparse variation; (S160) Calculate an average variation of a segment; (S165) Normalize and store an average variation of each segment; (S170) Calculate, normalize and store an average movement of each segment; (S180) Calculate an overall importance of each segment

PURPOSE: An image format conversion method for a 3D television receiver and a device thereof are provided to convert left/right images of an interlaced scanning image format which is decoded in the 3D television receiver into a top/bottom 3D image format, thereby transmitting the left/right images to a general 3D television. CONSTITUTION: A reference image decoder(350) decodes an encoded reference image of a first format which includes an interlaced scanning format. An additional image decoder(360) decodes an encoded additional image of the first format which includes the interlaced scanning format. A 3D format converter(370) generates a 3D image of a progressive scanning format.

Abstract:
PURPOSE: An apparatus and a method for converting a three-dimensional image mode and a two-dimensional image mode are provided to add a function for displaying a binocular image in a two-dimension. CONSTITUTION: A three-dimensional image offering unit(221) offers a three-dimensional image to a user by using an image. A two-dimensional image offering unit(222) offers a two-dimensional image to the user based on the image of a three-dimensional display devcie. A mode selecting unit(223) selectively execute one of the three-dimensional image offering unit and the two-dimensional image offering unit.
Abstract:
PURPOSE: An apparatus and method for multiplexing multimedia data are provided to variably multiplex multimedia data based on the size of a packet determined according to the attribute of the multimedia data. CONSTITUTION: Based on the attributed of multimedia data, a multiplexing control unit(520) determines the size of a packet variably. The multiplexing control unit determines an FEC(Forward Error Correction) type of the multimedia data variably. Based on the determined size and FEC of the packet, PSI(Program Specification Information) generation unit(540) generates PSI(Program Specification Information) data. A multiplexing unit(550) multiplexes the multimedia data and the PSI data respectively.
