  • Patent number: 10582148
    Abstract: Access point pictures designated as randomly accessible positions are I pictures or P pictures. Information indicating the decoding sequence (I1, P1, B1, B2, B3, B4, P2, . . . ) of pictures functioning as access points and attribute information (picture_type) indicating whether a picture functions as an access point or is necessary for decoding of the access point following a given access point are recorded on the video information recording medium. Random access is possible even if the GOP interval is lengthened.

  • Patent number: 10529382
    Abstract: In a recording medium on which is recorded a multiplexed stream including a plurality of first packets (V_main) constituting a first I-picture in a first video stream and a plurality of second packets (V_sub) constituting a second I-picture in a second video stream, information for identifying the first I-picture and information for identifying the second I-picture are recorded on the medium. A recording medium can thereby be obtained that enables the rapid detection, from a small amount of information, of a particular picture included in a stream such as a TS in which multiple content streams are multiplexed.

  • Publication number: 20190296647
    Abstract: A device and method for controlling a power supply. The method includes: a voltage signal in a primary winding is delayed, and the delayed voltage signal is sampled and held after a time when a rectifying diode stops conducting a current, then the sampled and held signal is used as a feedback signal of the power supply. Therefore, only one sampling and holding circuit is needed, the area of the circuit can be reduced and the cost of the integrated circuit can be decreased, meanwhile regulation characteristics are not deteriorated.

  • Patent number: 10334218
    Abstract: A video reproduction device (100) reproduces expanded video data (DV1) whose brightness dynamic range is wider than a standard video. The video reproduction device (100) includes a brightness information adjustment unit (150). The brightness information adjustment unit (150) changes first output brightness levels of the expanded video data (DV1) to second output brightness levels. When the expanded video data (DV1) is reproduced at a second reproduction speed faster than a first reproduction speed which is a normal speed, the brightness information adjustment unit (150) reduces the first output brightness levels to the second output brightness levels.

  • Patent number: 10298135
    Abstract: A device and method for controlling a power supply. The method includes: monitoring a feedback signal of a feedback terminal; determining whether the feedback signal of the feedback terminal is not a pulse signal; and terminating an on/off operation of a switching element when the feedback signal of the feedback terminal is not a pulse signal. Therefore, an abnormal status of the device can be correctly detected with a simple structure when the feedback terminal is open or is shorted with other terminals, while an error operation and a damage of the device can be avoided.
