Patent number: 10148901Abstract: A remotely controlled device receives a first command from a remote control (RC) but does not execute the command. Instead, the remotely controlled device waits to receive the first command within a threshold period, and if not received twice within the period, the first command is then executed. However, the first command is not executed if it is received twice, at which point the name of the corresponding RC key is announced. A second double command caused by a second double press of the same key on the RC causes the remotely controlled device to announce the function of the key. The logic may be executed in the RC as well as or in lieu of executing it in the remotely controlled device.Type: GrantFiled: February 9, 2018Date of Patent: December 4, 2018Assignee: Sony CorporationInventors: Brant Candelore, Mahyar Nejat, Peter Shintani
