Publication number: 20040252982Abstract: A recording apparatus, allowing a user to view video data while dubbing of other video data, which requires the actual time of the video data, is executed. The recording apparatus comprises a view buffer, and an encode buffer. A MPEG2 decoder decodes a VOBU for dubbing and a VOBU for viewing in parallel by time-sharing, writes the decoded VOBU for dubbing into the encode buffer, and writes the decoded VOBU for viewing into the view buffer. A MPEG2 encoder encodes the decoded VOBU for dubbing stored in the encode buffer. The MPEG2 decoder performs the decoding and the writing at a higher processing rate than a display rate for reproduction. A display control unit reads and reproduces, at the display rate, the decoded VOBU for viewing which is written into the view buffer at the higher processing rate.Type: ApplicationFiled: June 10, 2004Publication date: December 16, 2004Inventors: Yuji Iwahara, Ryuichi Hori, Youichi Yamamoto, Masako Ninomiya

Publication number: 20040155596Abstract: An inverter circuit for discharge lamps for multi-lamp lighting in which the value of a negative resistance characteristic of a fluorescent lamp is controlled, and an excessively set reactance is eliminated by causing a shunt transformer to have a reactance exceeding the negative resistance characteristic, whereby shunting characteristics high in performance are obtained while reducing the size of the circuit. In an inverter circuit for discharge lamps for multi-lamp lighting, two coils connected to a secondary winding of a step-up transformer of the inverter circuit are arranged and magnetically coupled to each other to form a shunt transformer for shunting current such that magnetic fluxes generated thereby are opposed to each other to cancel out. Discharge lamps are connected to the coils, respectively, with currents flowing therethrough being balanced with each other.Type: ApplicationFiled: February 9, 2004Publication date: August 12, 2004Inventors: Masakazu Ushijima, Koji Kawamoto, Youichi Yamamoto, Minoru Kijima

Publication number: 20030190150Abstract: A disk device provided in a record/playback device stores a plurality of programs as well as a record-setting content and playback history of each program. When specified by a remote controller as to a program to be played from a program list displayed on a television screen, a serial judging unit judges whether the specified program is an episode in a serial having another episode that was recorded prior to the specified program, by comparing the record-setting content of each of the programs. If judged in the affirmative, a playback judging unit judges whether the other episode has yet to be played, by referring to the playback history of the other episode. If judged in the affirmative, a presentation unit has displayed on the television screen that there is an unplayed episode in the serial. Then, when instructed by a user to start the playback from the unplayed episode, a playback unit plays the unplayed episode.Type: ApplicationFiled: February 21, 2003Publication date: October 9, 2003Inventors: Masahiro Kawasaki, Tohru Suetomo, Youichi Yamamoto

Publication number: 20030164984Abstract: MPEG encoder 3 generates VOBUs from broadcast waves and writes them to HDD 5. Record controlling unit 10 controls MPEG encoder 3 and HDD 5 to repeatedly perform this writing process for achieving a continuous recording function. Record controlling unit 10 also judges if there are points of time at which, by a broadcast station, (i) a service period is switched to an out-of-service period, and (ii) an out-of-service period is switched to a service period. Record controlling unit 10 suspends the writing to the HDD 5 at a point of time at which a service period is switched to an out-of service period, and resumes the writing to the HDD 5 at a point of time at which an out-of-service period is switched to a service period.Type: ApplicationFiled: February 10, 2003Publication date: September 4, 2003Inventors: Tohru Suetomo, Masahiro Kawasaki, Youichi Yamamoto

Patent number: 6594669Abstract: A newly defined data type is added to a database management system. Information about a query component assisting in querying data belonging to the newly defined data type is registered along with data type information in a query component information. If the data type being queried is the newly added data type, the query component information is searched to find a query component for assisting queries to data belonging to the particular data type. The matching query component is activated and a screen is displayed to input information needed to the query data belonging to the data type.
