Patent number: 7062149Abstract: Herein disclosed is an apparatus for decompressing compressed data which can decompress compressed data at a high speed as compared with the prior art decompressing apparatus. The apparatus comprises recording means, reading means, decompressing means, at least one frame memory, picture designating means, and control means. The recording means is designed to record the compressed data to be decompressed by the decompressing means. The recording means includes at least one random access memory for recording the compressed data in order to enable the random access to read each GOP in any order. The reading means is adapted to read the compressed data to be decompressed by the decompressing means from the recording means. The decompressing means is operated to decompress the compressed data read from the recording means by the reading means. At least one frame memory is operated to store the decompressed data produced by the decompressing means.Type: GrantFiled: March 28, 2001Date of Patent: June 13, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroyuki Seki, Akihiko Yamazaki, Keiichi Miyazaki, Tsutomu Hashimoto, Ken Monda

Patent number: 6892025Abstract: A picture signal reproducing apparatus for synchronously reproducing a variety of digital coded data strings, comprises: data transmission controlling unit for inputting a series of digital multiplexed coded data strings including a plurality of packs connected with each other in serial, each of the packs having a SCR, and inserting a reproduction unit switching information at a seamless point between two packs in the series of digital multiplexed coded data strings according to the SCR for each of the packs; and reproduction controlling unit for detecting the seamless point on the basis of the reproduction unit switching information from the series of digital multiplexed coded data strings to synchronously reproduce the variety of digital coded data strings at the detected seamless point.Type: GrantFiled: March 28, 2001Date of Patent: May 10, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Motoi Togashi, Ryoji Yamaguchi, Tsutomu Hashimoto, Ken Monda, Keiichi Miyazaki

Patent number: 6847687Abstract: According to the data amount and the nature of a video stream and an audio stream included in a program stream which is to be decoded, an audio and video processing apparatus performs processing while allocating higher priority to one or the other of the video and audio streams. Without any increase in circuit complexity or clock speed, this apparatus can reproduce streams in at least two formats, in which the ratios of the amounts of encoded signal data and of the amounts of calculation required for decoding for the video and the audio are very different.Type: GrantFiled: March 1, 2001Date of Patent: January 25, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takeshi Fujita, Takashi Katayama, Masahiro Sueyoshi, Kousuke Nishio, Masaharu Matsumoto, Akihisa Kawamura, Kazutaka Abe, Ryoji Yamaguchi, Makoto Meiarashi, Ken Monda

Patent number: 6842485Abstract: A compressively coded data reproduction apparatus and method for separating compressively coded video, audio, and additional data, data from a stream, outputting these data performing head detection on video and audio frames; decoding the video frames to output video data; decoding the audio frames to output audio data; judging whether a detected head frame is a video frame or an audio frame corresponding to a designated entry point start time information being among the additional data of the detected frame, outputting a decoding request when the detected frame is judged as a video and/or audio frame corresponding to the start time, and outputting an output request at the point of time when both of the video frame and the audio frame have been decoded. The system can output a video frame and an audio frame at the same time, within a prediction of video frame unit or audio frame unit, when starting reproduction of compressively coded data from an entry point.Type: GrantFiled: March 29, 2001Date of Patent: January 11, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Ken Monda, Keiichi Miyazaki, Akihiko Yamazaki, Hirotoshi Kobayashi
