Publication number: 20080101767Abstract: An optical disk for recording stereoscopic videos and high-quality video signals and a system for reproducing the videos and signals from the optical disk are made compatible with the conventional video reproducing system. A reproducing device which is used for reproducing stereoscopic videos and high-quality videos obtains stereoscopic video or high-quality videos by reproducing both first and second interleaved blocks on the optical disk in which first and second video signals are alternately recorded on the left and right sides by dividing the first and second video signals into frame groups of one GOP or more and a reproducing device which is not used for reproducing the stereoscopic videos and high-quality videos obtains ordinary videos by only reproducing either the first or second interleaved block by jumping tracks.Type: ApplicationFiled: October 31, 2007Publication date: May 1, 2008Applicant: Matsushita Electric Indusrial Co., Ltd.Inventors: Mitsuaki Oshima, Yoshiichiro Kashiwagi, Takumi Hasebe, Kazuhiro Tsuga, Kazuhiko Nakamura, Yoshihiro Mori, Masayuki Kozuka, Yoshihisa Fukushima, Toshiyuki Kawara, Yasushi Azumatani, Tomoyuki Okada, Kenichi Matsui

Patent number: 7274860Abstract: An optical disk for recording more than one system stream containing audio data and video data. The audio data and video data of the plural system streams are recorded to the optical disk, and are interleaved such that the difference between the input start times of the video data and audio data to the video buffer in the video decoder and the audio buffer in the audio decoder is less than the reproduction time of the number of audio frames that can be stored in the audio buffer plus one audio frame.Type: GrantFiled: February 20, 2003Date of Patent: September 25, 2007Assignee: Matsushita Electric Induatrial Co., Ltd.Inventors: Tomoyuki Okada, Yoshihiro Mori, Kazuhiro Tsuga, Hiroshi Hamasaka, Hideshi Ishihara, Kazuhiko Nakamura, Takumi Hasebe

Publication number: 20040160635Abstract: The invention provides an imaging apparatus that when recording image data that includes an object, associates metadata for that object with the image data. The imaging apparatus comprises: an imaging unit that takes images of an object; a receiving unit that receives an object signal from the outside; and a judgment unit that determines whether or not the transmitter that transmits the object signal is included in the image when an object signal is received by the receiving unit; and when the judgment unit determines that the transmitter is included in the image, a recording unit records the information related to the transmitter, with the image data with which the information is associated, on a recording medium.Type: ApplicationFiled: February 17, 2004Publication date: August 19, 2004Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroshi Ikeda, Takumi Hasebe, Kazutaka Nishio

Patent number: RE37994Abstract: An encoding method for producing specific encoded data by calculating the data occupancy of a decoding buffer memory of a particular size that is used when decoding the encoded data during reproduction, defining the allocated code size of a particular period based on the calculation result, and compression coding the signal of a particular period to the allocated code size. The data occupancy is calculated on the assumption that virtual encoded data is transferred to the decoding buffer memory following the transfer of the first-encoded data to the decoding buffer memory. The data occupancy when the last data in the first encoded data is decoded is calculated as the final buffer occupancy Be. The data occupancy when the encoding process producing the second encoded data is begun is an initial buffer occupancy Bi where the initial buffer occupancy Bi is less than the final buffer occupancy Be, and thus allocated code size is defined based on the change in the data occupancy.Type: GrantFiled: August 10, 2001Date of Patent: February 18, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hideki Fukuda, Kazuhiro Tsuga, Takumi Hasebe, Yoshihiro Mori, Tomoyuki Okada, Kazuyoshi Horiike
