Abstract
Provided is a broadcasting control apparatus configured to generate a system time for broadcasting control, the system time being synchronized with a reference time in accordance with a predetermined time protocol, and configured to correct, when leap second adjustment information indicating that leap second adjustment is scheduled to be completed at a first time in the reference time is received, the system time by a correction amount depending on a time length D over a correction period having the time length D from a second time earlier than the first time, the time length D being set such that a correction amount per second of the system time is equal to or less than a cycle corresponding to an inverse of a video frame rate.
Claims19
A broadcasting control apparatus comprising:
- a memory storing instructions;
- and
- one or more processors configured to execute the instructions to:
- generate a system time for broadcasting control, the system time being synchronized with a reference time in accordance with a predetermined time protocol;
- and
- when leap second adjustment information indicating that leap second adjustment is scheduled to be completed at a first time in the reference time is received, correct the system time by a correction amount depending on a time length D over a correction period having the time length D from a second time earlier than the first time,
- wherein the time length D is set such that a correction amount per second of the system time is equal to or less than a cycle corresponding to an inverse of a video frame rate.
A broadcasting control method comprising:
- generating a system time for broadcasting control, the system time being synchronized with a reference time in accordance with a predetermined time protocol;
- and
- correcting, when leap second adjustment information indicating that leap second adjustment is scheduled to be completed at a first time in the reference time is received, the system time by a correction amount depending on a time length D over a correction period having the time length D from a second time earlier than the first time,
- wherein the time length D is set such that a correction amount per second of the system time is equal to or less than a cycle corresponding to an inverse of a video frame rate.
(canceled)
A non-transitory computer-readable recording medium storing a computer program therein, the computer program causing a processor of a broadcasting control apparatus to execute:
- generating a system time for broadcasting control, the system time being synchronized with a reference time in accordance with a predetermined time protocol;
- and
- correcting, when leap second adjustment information indicating that leap second adjustment is scheduled to be completed at a first time in the reference time is received, the system time by a correction amount depending on a time length D over a correction period having the time length D from a second time earlier than the first time,
- wherein the time length D is set such that a correction amount per second of the system time is equal to or less than a cycle corresponding to an inverse of a video frame rate.
