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.

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.

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.

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 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.

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.

Abstract: In a reader for an RFID tag for near-field wireless communication, an antenna selection switch includes a plurality of antennae arranged with an extent within a predetermined range for transmitting and receiving data to and from an RFID tag, and selects one antenna to be used for transmission and reception of data from among the plurality of antennae. A detection part acquires, when a carrier wave transmitted from the RFID tag is received by any of the plurality of antennae, information indicative of an antenna selected by the antenna selection switch under the control of an antenna changeover controlling part.
