摘要： Appearance of simultaneous connections is provided to devices that support two wireless protocols which are not permitted to operation simultaneously. As an example the method and systems disclosed are applied to the communication between a phone and a smartwatch wherein Bluetooth (BT) classic protocol is used for e.g. voice commands and phone calls and Bluetooth low Energy (BLE) protocol is used for data notifications. In a first embodiment of the disclosure automatic mode switching between BT and BLE is provided. In a second embodiment a dual-ID device utilizes separate IDs for both protocols in time multiplexed connections. It operates as logically independent devices with individual ID's although physically it is a single device.

摘要： A time synchronization method that is capable of selecting whether synchronization, by a timepiece unit that generates a time signal synchronized with a standard time and outputs it to an exterior, with the time is performed by time information obtained by receiving a radio wave including information relating to the time, or is performed by means of a holdover performed using a clock signal from an internal or external clock source. A schedule having a first time period in which the above-mentioned time information is used, and a second time period by means of the holdover is determined according to temporal reception characteristics of the radio wave at a reception location of the radio wave, and according to the schedule, supplying the timepiece unit with the time information or supplying the timepiece unit with the clock signal from the internal or external clock source.

摘要： A system for processing a television signal including a data component, such as extended data services data, includes a decoder for processing the data component to provide data representing time information. A control device responds to the data for modifying time information, e.g., time of day, that is maintained in the system. The time information decoded from the video signal is compared to the time information maintained in the system to determine a time difference. If the time difference is in a predetermined range, the time difference indicates that the time information from the television signal is invalid. The control device responds to the time difference being in the predetermined range by preventing modification of the time information maintained in the system. A user may provide an input via a device such as a remote control to control the manner in which the control device responds to the time difference.

摘要： A television receiver includes a decoder for decoding a data component of a television signal, such as extended data services (EDS) data. The data component includes data representative of time of day information. A controller in the receiver processes the time of day information to set the time of day stored in the television receiver to a time value that is accurate to seconds.

摘要： Broadcast signal receiver which has an internal clock controls an internal or external tuner which receives a plurality of broadcast signals to tune to a predetermined broadcast signal which includes time data indicating a local time. The broadcast signal tuned to is supplied as a tuned output signal. The time data is extracted from the tuned output signal and the internal clock of the broadcast signal receiver is automatically set to the local time indicated by the time data.

摘要： In a VCR having an automatic time setting function, a receiving circuit receives a current time signal from a broadcasting station, and a wave-shaping circuit converts the current time signal from the receiving circuit to a digital signal. A decoder decodes the digital current time data from the wave-shaping circuit, and a memory stores the decoded current time data from the decoder in frame units. A frame detector detects a starting point of each frame of the current time data from the wave-shaping circuit and resets the current time data of a frame previously stored in the memory upon detecting the starting point. A tuner tunes audio and video signals from the broadcasting station to a reference frequency, and a control unit controls the operation of the VCR and converts the current time data to the current time. An on-screen display unit superimposes a timer signal or the current time on the video signal under the control of the control unit and outputs the resultant signal to an external display unit. A character display unit displays the current time from the control unit, and a key matrix unit applies either a summer time display function signal or a time siren function signal to the control unit according to a user's selection.
