Publication number: 20180182350Abstract: A display apparatus transmits a picture acquisition request for getting picture information to an external image apparatus connected through a predetermined interface to the display apparatus from the external image apparatus at predetermined intervals and gets a plurality of pieces of picture information from the external image apparatus to be displayed. The plurality of pictures may be switched at predetermined intervals, for example, to be displayed, so that the plurality of pictures may be displayed in a so-called slide show manner. A plurality of pictures for thumbnail may be produced from the plurality of pieces of picture information and be arranged together to be displayed in one picture screen of a display device.Type: ApplicationFiled: February 26, 2018Publication date: June 28, 2018Inventors: Toshiyuki Kurita, Hitoaki Owashi

Publication number: 20180167671Abstract: While presenting on a display apparatus videos of high picture quality obtained from portable video processing apparatuses such as a camera and a cellular, it is possible to communicate with the Internet and/or a home network. A display apparatus includes a first radio communication unit capable of receiving video information by radio from an external video processing apparatus, a second radio communication unit capable of connecting by radio to a network, and a control unit for controlling assignment of connection by radio transmission for each of the first and second radio communication units. The control unit assigns connection of the first radio communication unit with higher priority and controls the assignment of the transmission rate such that the transmission rate between the first radio communication unit and the external video processing apparatus is more than that between the second radio communication unit and the network.Type: ApplicationFiled: February 7, 2018Publication date: June 14, 2018Applicant: HITACHI MAXELL, LTD.Inventors: Toshiyuki Kurita, Hitoaki Owashi

Patent number: 9769448Abstract: An interface is realized that can prevent video signals from being copied easily and which uses a luminance/color difference signal transmission scheme with an excellent harmony with a television circuit. In a video transmission using a digital interface, colorimetry information for defining the conversion from the luminance/color difference signal into a primary color signal and video aspect ratio information are transmitted along with the luminance/color difference type video signal. This allows reproduction of video with high quality and high resolution and also realizes a copyright protection which allows only the users authorized by key information to use the content of the video. With this transmission scheme, it is possible to provide a transmitting apparatus, a receiving apparatus and an interface which highly harmonize with a rationalized television-based circuit.Type: GrantFiled: April 11, 2016Date of Patent: September 19, 2017Assignee: HITACHI MAXELL, LTD.Inventors: Toshimitsu Watanabe, Hitoaki Owashi, Kazuhiko Yoshizawa

Patent number: 8699864Abstract: A method and apparatus is provided for receiving and/or reproducing a digital signal, capable of efficiently recording a compressed, packeted digital signal and inhibiting a copy thereof. An input packet signal is added with a time stamp indicating a relative time of an arrival of the packet, and the packet signals of digital information with the added time stamps are recorded at reduced intervals therebetween. In reproducing, a packet interval adjusting circuit restores the original packet intervals in accordance with the time stamps, and then a time stamp change circuit changes at least one bit of the time stamp and thereafter outputs the digital information.Type: GrantFiled: March 10, 2009Date of Patent: April 15, 2014Assignee: Hitachi Consumer Electronics Co., Ltd.Inventors: Hitoaki Owashi, Hiroo Okamoto, Kyoichi Hosokawa, Takaharu Noguchi
