Patent number: 11977362Abstract: In the conventional distributed control system, since each control device updates the data area at a timing when a control packet is received, in a case where there is a difference in communication delay between the control devices or in a case where the communication delay includes jitter, it is difficult to match the contents of data in all the control devices in a case of focusing on a certain moment during system operation. Therefore, depending on the start timing of a control application, the control application operates on the basis of different data between the control devices, thus limiting control performance improvement. Accordingly, time slots on the network are allocated according to the result of a calculation unit, and a cyclic memory synchronization update unit synchronizes the timing of reflecting data in the input/output and the cyclic memory and the timing of using data of a cyclic memory.Type: GrantFiled: August 19, 2020Date of Patent: May 7, 2024Assignee: HITACHI, LTD.Inventors: Tatsuya Maruyama, Yusaku Otsuka, Hidenori Omiya, Toshiki Shimizu, Iori Kobayashi, Kazutaka Onishi, Noritaka Matsumoto

Publication number: 20100319047Abstract: There is provided a digital broadcast receiver that can readily cope with a change in a time lag between simultaneous broadcasts and opening of a new broadcast station and that enables smooth switching between the simultaneous broadcasts without addition of devices entailing performance of enormous amounts of processing. A characteristic showing that a coding rate increases when a large difference arises between a current frame and a preceding frame of a video signal is utilized for MPEG2 and MPEG4-AVC standards employed as schemes for coding a video signal in a ground digital broadcast. A per-frame coding rate of first broadcast coded video data and a per-frame coding rate of second broadcast coded video data are ascertained. A lag between an output time of the first broadcast and an output time of the second broadcast is detected from time shifts in the thus-ascertained coding rates and a lag between internal clock signals.Type: ApplicationFiled: June 17, 2010Publication date: December 16, 2010Applicant: Panasonic CorporationInventors: Toshikazu MITSUTAKE, Noritaka Shimizu, Rie Fukushige
