Patent number: 7433411Abstract: A decoding apparatus for selectively decoding compressed video or audio signal included in a data signal. The decoding apparatus includes a demultiplexer that receives and separates a data signal from a compressed input signal. A video decoder and an audio decoder are provided to decode compressed video or audio signals stored in a decoder buffer. The decoding apparatus uses a memory to store the data signal separated by the demultiplexer, and a CPU to analyze the data signal stored in the memory. The CPU causes the data signal analyzed by the CPU to be stored in the decoder buffer if the analyzed data signal includes a compressed video signal or a compressed audio signal, and the compression method used for the compressed video signal or the compressed audio signal included in the data signal can be decoded by the video decoder or the audio decoder.Type: GrantFiled: January 23, 2004Date of Patent: October 7, 2008Assignee: Hitachi, Ltd.Inventors: Taku Nakamura, Yukio Fujii, Kenji Katsumata, Hiroyuki Koreeda

Patent number: 7352877Abstract: In order to avoid content deteriorations caused by embedment of a digital watermark into a moving picture, a process to search a picture for a motion and a process to filter a picture for medical care must be carried out, raising a processing cost. It is thus difficult to implement equipment for processing such pictures at a low cost. In a compound apparatus for encoding compressed code of a moving picture by employing a unit for embedding a digital watermark into a picture, a digital-watermark embedment quantity is determined by using a motion vector and a quantization parameter in a process to embed a digital watermark into the picture. It is thus no longer necessary to carry out the process to search a picture for a motion and the process to filter a picture for medical care for embedment of a digital watermark so that the cost of the entire apparatus can be reduced substantially.Type: GrantFiled: July 17, 2003Date of Patent: April 1, 2008Assignee: Hitachi, Ltd.Inventors: Yoshifumi Fujikawa, Yukio Fujii, Koichi Terada

Publication number: 20060233522Abstract: A video processing technique which enables users to effectively watch highlight scenes while listening to audio part thereof in a short period of time is disclosed. Upon input of video data, highlight scene data describing therein a highlight scene(s) in the video data is input or generated. Then, based this highlight scene data, determine a default playback parameter. Control is provided to reproduce the highlight scene(s) of the video data in a way such that when inputting a parameter for determination of a playback scene(s), this input playback parameter is used while giving thereto higher priority than the default playback parameter.Type: ApplicationFiled: March 7, 2006Publication date: October 19, 2006Inventors: Kazushige Hiroi, Yoshifumi Fujikawa, Norikazu Sasaki, Riri Ueda, Akio Hayashi, Yukio Fujii, Atsuo Kawaguchi

Publication number: 20060236145Abstract: A contents reproduction device realizes reduction of power consumption by controlling power supply control according to the input contents. More specifically, in the contents reproduction device, the PSI analysis unit analyzes additional information in the inputted contents so as to check whether video contents are contained or the signal detection unit checks whether the inputted contents contain a video signal. According to the check result, the video information detection unit detects whether the inputted contents contain video information and outputs the detection result to the power control unit. When the inputted contents contain video information, the power control unit supplies power to the display. When no video information is contained, the power control unit stops power supply to the display and turns off power supply to the display.Type: ApplicationFiled: August 31, 2005Publication date: October 19, 2006Inventors: Takafumi Yuasa, Yukio Fujii, Kazuhiko Tanaka, Koji Hosogi, Hiroaki Nakata, Masakazu Ehama
