Patent number: 7450774Abstract: An apparatus and a method of changing a bit rate of a compressed image bit stream by changing a codeword so as to easily change the bit rate and reduce a changing loss. The apparatus for changing a bit rate, in which an input bit stream generated by an image compression encoding method is changed into an output bit stream having a desired bit rate, includes a changing codeword determiner which selects codewords to replace the codewords of the input bit stream, and a codeword changer which changes the codewords of the input bit stream into the codewords selected by the changing codeword determiner. The method and the apparatus can be applied to image services provided through the Internet and receiving apparatuses supporting the Personal Video Recorder (PVR) function. Particularly, the method of changing the bit rate of a compressed image bit stream changes the codewords of input transform coefficients so as to easily change the bit rate and reduce the changing loss.Type: GrantFiled: April 22, 2002Date of Patent: November 11, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Cheul-hee Hahm, Jae Moon Jo

Patent number: 6801294Abstract: There is provided an apparatus for recording and/or reproducing a moving picture using key frames by which the overall scenario of moving picture contents can be ascertained during a trick-play mode, and a method thereof. The recording apparatus includes a recording medium and recording apparatus for marking a representative picture position detected when there is a scene change among coded moving picture data streams, and recording the moving picture data streams on the recording medium. The scene change is determined based on distribution characteristics of macro blocks of frame units for the input coded moving picture data streams. The moving picture reproducing apparatus includes a recording medium having coded moving picture streams and a representative picture position detected when there is a scene change recorded thereon, and reproducing apparatus for searching for the representative picture position recorded on the recording medium and then reproducing a representative picture.Type: GrantFiled: November 21, 2002Date of Patent: October 5, 2004Assignee: Samsung Electronics Co., Ltd.Inventor: Jae-moon Jo
