The method includes confirming neighboring devices capable of wired and/or wireless communication; allocating audio channel information to confirmed neighboring devices; encoding the channel information and reproduction synchronization information as index information; transmitting the index information together with a music data file; receiving the encoded index information and music data; decoding the allocated channel information and the synchronization information; and outputting music data corresponding to the allocated channel.

Abstract: An image processing method and apparatus for automatically rotating an image and a display unit, and an information storage medium storing image information. The apparatus including a photographing unit which generates image data and a rotation sensing unit which generates rotational information of a rotation state of the photographing unit. When an object is photographed, the rotation information of the image is obtained and stored together, and when the image is displayed, the rotation is analyzed and the image and display unit are automatically rotated. When an image including moving picture information is watched, an image always optimized to be horizontal without additional work by a user can be seen.

Abstract: A method for determining a position at which a polygon to be clipped is situated with respect to a clipping plane to perform clipping processing, includes the steps of selecting a bounding volume sufficiently enclosing the polygon, and judging a position at which the bounding volume is situated with respect to the clipping plane to be the position at which the polygon is situated.

Abstract: A multiprocessor graphics system having a pixel link architecture, includes: 1) a plurality of sub-graphics systems each of which assigned to each of a plurality of sub-screens provided by sectioning a display screen; and 2) a ring network for connecting the plurality of sub-graphics systems. Each of the sub-graphics systems includes a geometry engine, a raster engine, a local frame buffer and a pixel distributor. An interconnection network bottleneck between the raster engine and frame buffer is removed and a conventional memory system can be used by reducing the number of data transmissions between the raster engine and frame buffer while maintaining image parallelism and object parallelism.

Abstract: A real-time rendering method for selectively performing bump mapping and Phong shading processes and a rendering apparatus therefor are provided. The rendering method includes the step of calculating a ambient factor, the step of bump-mapping a diffuse factor and selectively outputting the bump-mapped diffuse factor or the diffuse factor prior to the bump mapping according to a bump mapping/Phong shading selection signal, the step of bump-mapping a specular factor and selectively outputting the bump-mapped specular factor or the specular factor prior to the bump mapping according to the bump mapping/Phong shading selection signal and the step of summing the ambient factor, the selectively output diffuse factor and the selectively output specular factor and obtaining the value of intensity. Therefore, bump mapping and Phong shading processes are selectively performed. Also, there is no discontinuity at the borders of each polygon.

Abstract: An element generator for a dither matrix comprises a logic device which receives a row address and a column address and performs a logic operation thereon so as to produce a dither element corresponding to the row address and the column address, which is implemented at low cost and has an advantage in that the processing speed is increased. The dithering apparatus comprises a dither-matrix element generator, a comparator, an adder and a selector. The comparator compares the output of the dither-matrix element generator with lower-bit data of the original image data. The adder adds a predetermined number to upper-bit data of the original image data. The selector selects one between the upper-bit data and the adder output, in accordance with the output of the comparator, so as to produce the selected one as the dithered image data. Dithering is thereby performed via hardware, which leads to an increased processing speed.

Abstract: The present invention provides a unified image and graphics processing system that provides both image and graphics processing at high speeds. The system includes a parallel vector processing unit, a graphics subsystem, a shared memory and a set of high-speed data buses for connecting all of the other components. Generally, the parallel vector processing unit includes a series of vector processors. Each processor includes a vector address generator for efficient generation of memory addresses for regular address sequences. In order to synchronize and control the vector processors' accesses to shared memory, the parallel vector processing unit includes shared memory access logic. The logic is incorporated into each vector processor. The graphics subsystem includes a series of polygon processors in a pipelined configuration. Each processor is connected in the pipeline by a first-in-first-out (FIFO) buffer for passing data results.
