Abstract: Provided are a moving image reception device, a control method, and a program which can reduce a sense of discomfort felt by a user in a situation in which a moving image generated by a moving image transmission device in response to an operation on the moving image reception device is displayed on the moving image reception device. An operation data transmission unit transmits operation data corresponding to an input operation of the user to a cloud server. An image data reception unit receives, from the cloud server, interval data representing a time from reception of the operation data to a start of generation of the frame image based on this operation data in the cloud server. A transmission timing control unit controls a timing of the transmission of the next operation data, on the basis of the interval data.

Abstract: To reduce the possibility of occurrence of problems such as missing frames and an increase in display delay even if a disturbance occurs in a communication path. A reception device includes a reception unit that sequentially receives image information transmitted by a transmission device at a given first interval by wireless communication, a display unit that sequentially displays frame images on the basis of the image information in accordance with a display clock and generates display time information indicating a time corresponding to the update time of the frame image, and a control unit that calculates a second interval indicating an interval at which the frame images are displayed on the basis of plural pieces of the display time information and controls the update cycle of the frame image in accordance with the display clock such that the second interval approximates to the first interval.

Abstract: An image data acquirement section of an image processing apparatus acquires data regarding a frame of a moving image generated by a server. A decoding/decompression section repeats a cycle of a decoding/decompression process for each of frames at a rate higher than the frame rate of the moving image. An image processing section repeats a cycle of applying a necessary image process to each of the frames at the rate higher than the frame rate of the moving image. The display control section outputs the data regarding the frame ready for displaying to a display panel at the rate higher than the frame rate of the moving image.

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.
