Abstract: A 3D(Dimensional) contents scene playback method and a device thereof are provided to support 3D text through a scene descriptor by suggesting a 3D text node including text information and disparity information of the text information to the scene descriptor. An MPEG(Moving Picture Expert Group)-4 control signal generator generates an MPEG-4 control signal including a scene descriptor. The scene descriptor includes 3D text node information for displaying text in 3D. The 3D text node information includes a left string field storing a first text corresponding to a left staring point, a right string field storing a second text corresponding to a right starting point, and a disparity field storing information for disparity of the first and second text.

Abstract: An apparatus and a method for processing multi-channel audio signals are provided to enable active control for a user by controlling a multi channel audio signal according to channels using threshold through which human recognizes displacement of a sound source. A transmitting apparatus(100) comprises a multi channel audio encoder(102), a scene expression language encoder(104) and a multiplexer(106). The multi channel audio encoder generates multi channel audio stream by encoding the multi channel audio signal. The scene expression language encoder generates the scene expression language stream by encoding the multi channel audio control information. The multiplexer multiplexes the multi channel audio stream and the scene expression language stream. The multi channel audio control information includes data of controlling each channel signal individually. The data includes at least one of the number of the channels, the horizontal position of each channel signal, the vertical position of each channel signal, the horizontal transition speed of each channel signal, and the vertical transition speed of each channel signal. The horizontal and vertical transition speeds express the threshold by basic units to allow human to recognize the position of the sound source.

Abstract: PURPOSE: An apparatus and a method for adjusting moving picture time code and rate control buffer level are provided to prevent initial delay time generated in coding a first picture from being accumulated to the next picture during video communication. CONSTITUTION: A coding part(22) codes an input first picture within a screen and codes initial delay time generated when the first picture is coded in accordance with a rate control signal so that the initial delay time isn't accumulated to the next picture. The coded picture is stored in a buffer(23). A rate controller(24) generates the rate control signal, and calculates the number of pictures to be interlaced from the pictures stored in the buffer(23). A time code generator(25) generates the time code of the next picture in accordance with the number of pictures to be interlaced calculated in the rate controller.

Abstract: PURPOSE: A method for dividing image into areas of macro block and constructing a background mosaic is provided for object-based coding of an image having a motionless background. CONSTITUTION: An image consisting of a background having almost no motion obtained from a camera with a fixed position and focus and an object having slow motion is divided into a change area and unchanged area in macro block of the 16x16 pixel size most widely used as an elementary unit of coding in a method or apparatus for image coding by using the difference between the current image and the preceding one. From the result thereof, a background mosaic consisting only of macro blocks corresponding to areas that are not almost changed according to the elapse of time so that they are reconstructed whenever there is a change in the entire images for thereby maximizing the coding efficiency. Accordingly, it is easy to realize the background mosaic in real time, and the efficiency of object shape coding can also be maximized.
