Network electronic clock system and time correction method thereof

Abstract

The invention relates to a network electronic clock system and a time correction method thereof. The system comprises a hard clock module, a network clock module, a clock time correction module, a clock setting module and a system clock module. The hard clock module is used for producing the hard clock time, the network clock module is used for obtaining the network clock time, the clock time correction module is used for transmitting hard clock time correction commands after startup and transmitting network time correction commands after network activation, the clock setting module is used for respectively obtaining the hard clock time or the network clock time from the hard clock module or the network clock module as the system clock time and transmitting the system clock time after receiving the hard clock time correction commands or the network time correction commands, and the system clock module is used for receiving and storing the system clock time. Due to combination of hard clock time correction and network clock time correction, the accuracy of the electronic clock can be ensured to the largest extent. In addition, since an effective clock testing mechanism is adopted, a user is not informed of false clock information, and friendly prompts are provided for manual time correction of the clock.

Description

technical field [0001] The invention relates to electronic clock technology, more specifically, to a network electronic clock system and a time synchronization method. Background technique [0002] For IPTV, the network electronic clock generally refers to the system clock of the IPTV software operating system. There are generally two implementation schemes for the time synchronization of the system clock, one is the hard clock time synchronization scheme realized by hardware circuits, and the other is the network clock time synchronization scheme using the network clock server for time synchronization. The traditional design scheme of the network TV electronic clock is generally realized by one of the above-mentioned schemes. [0003] The hard clock time synchronization scheme requires a battery or power supply to continuously supply power to the clock circuit. Once the power is lost, the clock will be wrong and unavailable. In addition, the hard clock circuit will have a ...
