  • Publication number: 20210058601
    Abstract: A video data transmission unit transmits data generated by a video data generation unit to an HMD. A sensing data reception unit receives data transmitted from the HMD, the data including size data indicating a size of the data successfully received by the HMD. A required time specification unit specifies time it took for a round-trip communication in half-duplex wireless communication between a relay apparatus and the HMD. A generation control unit controls a size of the data generated by the video data generation unit per unit time based on the specified time, the size indicated in the size data, and a given target time regarding the round-trip communication.

  • Publication number: 20210058222
    Abstract: A required time specification unit specifies time it took for a round-trip communication in half-duplex wireless communication. A bitrate determination unit determines a value corresponding to a size of data generated by a video data generation unit per unit time based on the specified time and a given target time regarding the round-trip communication. The search occurrence estimation unit estimates whether or not a communication path search process with an HMD is occurring. The bitrate determination unit changes the determined value so that magnitude of change in the value corresponds to a result of the estimation.

  • Patent number: 10931913
    Abstract: Provided are a reception apparatus, a transmission apparatus, a control method, a transmission method, and a program that can control a frame image size of each frame image so that the frame image constituting a moving image is transmitted at an appropriate timing. A frame-image reception section receives a first frame image constituting the moving image. A control-data update section performs control so that the frame image size of a second frame image constituting the moving image, which is received after the first frame image, corresponds to a time required to receive the first frame image.

  • Patent number: 10855435
    Abstract: There are provided a communication apparatus, a generated data size controlling method, and a program for bringing a time required for a round-trip half-duplex communication close to a predetermined target time. A video data transmission section transmits data generated by a video data generation section to an HMD. A sensing data reception section receives data transmitted from the HMD. A required time identification section identifies the time required for the round-trip half-duplex communication between a repeating apparatus and the HMD. A generation control section controls a size of the data generated per unit time by the video data generation section on a basis of the identified time, the size of the data exchanged with the HMD in a round-trip communication, and a predetermined target time for the round-trip communication.

  • Publication number: 20200112354
    Abstract: Provided are a main beam direction determining device, a main beam direction determining method, and a program which are able to shorten a time required to determine a main beam direction. A secondary candidate sector selection unit selects a second number of primary candidates or a third number of primary candidates as a secondary candidate or candidates in accordance with a communication quality of communication by an HMD, the second number being smaller than a first number, the third number being smaller than the second number. A first sector level sweep process performing unit determines one of the secondary candidate or candidates as the main beam direction.

  • Publication number: 20200073104
    Abstract: An image reproducing device includes one or more processors. The processor acquires image group data including a plurality of images and tag information on at least one tag. The images relate to a biological sample along time series. The tag information relates to an operation on the biological sample and is associated with at least part of the images. The processor selects from the plurality of images using the tag information, images to be reproduced along the time series as reproduction selected images. The processor outputs to a display, data relating to the images for the reproduction selected images to be reproduced along time series.
