Patent number: 6487248Abstract: A video decoding device for a TV receiver, e.g., SDTV, decodes a compressed video signal transmitted from a transmitting side and displays the decoded signal. The device includes a first downsampling part for downsampling input data in a unit of block at a predetermined ratio; a display size converting part for dividing the downsampled result into a first group of data and a second group of data and after downsampling the first group of data, for performing screen format conversion for the downsampled first group of data into a display size; a memory for storing each of the converted first group of data and the second group of data; and an output part for downsampling the second group of data to correspond with the first group of data to thereby perform screen format conversion for the downsampled second group of data, when the second group of data is reproduced, and for outputting the first and second groups of data.Type: GrantFiled: February 16, 1999Date of Patent: November 26, 2002Assignee: LG Electronics Inc.Inventors: Il-Taek Lim, Seong Ok Bae, Seung-Jai Min, Sanghee Cho, Heesub Lee, Kyoungwon Lim, Cheol-Hong Min

Patent number: 6462746Abstract: A memory structure and method for implementing an on screen display (OSD) is disclosed. The present invention separates a command area, which stores small but frequently updated data causing fatal errors due to erroneous read, from a bitmap area, which stores relatively larger data, less frequently updated than the command area and which is not sensitive to errors. Thus, OSD memory structure and method allows an external host processor to effectively control the OSD process. Also, the command area further comprises a global command and a plurality of local commands, wherein the global command contains common control information to the local commands and control information other than OSD information, thereby allowing the external host processor to effectively control the OSD even when implementing multistandard OSD where a plurality of bitmap and commands for these bitmap are constructed in an external memory.Type: GrantFiled: April 22, 1999Date of Patent: October 8, 2002Assignee: LE Electronics Inc.Inventors: Seung-Jai Min, Kyung-Yun Lee, Seong-Ok Bae

Patent number: 6421695Abstract: An apparatus for a fast inverse discrete cosine transform (IDCT) by processing only non-zero IDCT input data including non-zero feeding unit connected to each row-column decomposed one dimensional IDCT input for feeding only non-zero input data during each cycle. The first 1-D IDCT and the second 1-D IDCT have the same structure, and 1-D IDCT core with a non-zero feeding unit at its front end. The 1-D IDCT core of the present invention is for performing IDCT operation based on the input scaling method, and the operation of the IDCT core consists of a cosine kernel selection operation using a received non-zero input, multiplication-and-addition, and a storing operation. The non-zero feeding unit for the first 1-D IDCT and the second one are different in their configuration. There are two different methods for implementing the first 1-D IDCT, a stored input feeding method and a zigzag scanned input feeding method.Type: GrantFiled: December 10, 1998Date of Patent: July 16, 2002Assignee: LG Electronics Inc.Inventors: Seong Ok Bae, Seung Jai Min
