Abstract
According to one embodiment, there is provided a synchronization control apparatus which synchronizes an STC counter value, based on TAI (Temps Atomique International: international atomic time) time, in each of systems which constitute a transmission system in a broadcasting system or a distribution system, the apparatus includes a processor or a dedicated arithmetic circuit configured to determine a time length in which the STC counter value laps, to calculate a remainder of the time length relative to the TAI time, and to convert the remainder to the STC counter value, thereby determining the STC counter value.
Claims8
A synchronization control apparatus which synchronizes an STC counter value, based on TAI (Temps Atomique International:
- international atomic time) time, in each of systems which constitute a transmission system in a broadcasting system or a distribution system, comprising:
- a processor or a dedicated arithmetic circuit,
- the processor or the dedicated arithmetic circuit being configured to determine a time length in which the STC counter value laps, to calculate a remainder of the time length relative to the TAI time, and to convert the remainder to the STC counter value, thereby determining the STC counter value.
A synchronization control method for synchronizing an STC counter value, based on TAI (Temps Atomique International:
- international atomic time) time, in each of systems which constitute a transmission system in a broadcasting system or a distribution system, comprising:
- a step of determining, in each of the systems, a time length in which the STC counter value laps;
- a step of calculating, in each of the systems, a remainder of the time length relative to the TAI time;
- and
- a step of converting, in each of the systems, the remainder to the STC counter value, thereby determining the STC counter value.
