Abstract
A synchronous communication apparatus includes an output unit configured to output a current time for synchronizing with another communication apparatus, a generation unit configured to generate a synchronous pulse at a predetermined frequency, and a change unit configured to, if a set time that is set as a time at which the generation unit starts generation of the synchronous pulse is not a time later than the current time, change the set time to a time later than the current time.
Claims10
A synchronous communication apparatus comprising:
- a processor;
- and
- a memory in communication with the processor, the memory storing instructions that, when executed by the processor, cause the processor to:
- output a current time for synchronizing with another communication apparatus;
- generate a synchronous pulse at a predetermined frequency;
- and
- if a set time that is set as a time at which the generation of the synchronous pulse starts, is not a time later than the current time, change the set time to a time later than the current time, wherein outputting the current time and changing the set time are performed in a time frame in which the synchronous pulse does not change in one period of the synchronous pulse.
A control method of a synchronous communication apparatus configured to output a current time for synchronizing with another communication apparatus and configured to generate a synchronous pulse at a predetermined frequency, the control method comprising:
- generating the synchronous pulse at the predetermined frequency;
- and
- if a set time that is set as a time at which generation of the synchronous pulse starts, is not a time later than the current time, changing the set time to a time later than the current time,
- wherein outputting the current time and changing the set time are performed in a time frame in which the synchronous pulse does not change in one period of the synchronous pulse.
A non-transitory storage medium storing a program causing a synchronous communication apparatus configured to output a current time for synchronizing with another communication apparatus and configured to generate a synchronous pulse at a predetermined frequency to execute a control method, the control method comprising:
- generating the synchronous pulse at the predetermined frequency;
- and
- if a set time that is set as a time at which generation of the synchronous pulse starts, is not a time later than the current time, changing the set time to a time later than the current time,
- wherein outputting the current time and changing the set time are performed in a time frame in which the synchronous pulse does not change in one period of the synchronous pulse.
