|1. (WO2017061428) COMMUNICATION SYSTEM, TRANSMISSION DEVICE, RECEIVING DEVICE, COMMUNICATION SYSTEM CONTROL METHOD AND PROGRAM|
|Applicants:||SONY INTERACTIVE ENTERTAINMENT INC.
|Title:||COMMUNICATION SYSTEM, TRANSMISSION DEVICE, RECEIVING DEVICE, COMMUNICATION SYSTEM CONTROL METHOD AND PROGRAM|
Provided are a communication system, transmission device, receiving device, communication system control method and program which make it possible to select an appropriate communication route in accordance with the time until data generated by the transmission device becomes available to be used by the receiving device. A first transmission unit (68a) transmits encoded data to a first receiving unit. A second transmission unit (68b) transmits encoded data to a second receiving unit. The maximum transmittable rate of the first transmission unit (68a) is higher than that of the second transmission unit (68b). When transmission is performed by the second transmission unit (68b), a pre-transmission processing execution unit (66) encodes data at a compression rate higher than a compression rate for transmission by the first transmission unit (68a). A transmission control unit (72) controls whether an HMD (14) uses data received by the first receiving unit or data received by the second receiving unit, on the basis of the time from the generation of the data until the data becomes available to be used by the HMD (14).
