Abstract

The invention discloses a method, system and device for keeping the clock synchronization of an NTP (Network Time Protocol) server. The method comprises the following steps of: synchronizing clocks from a telecommunication network time protocol (NTP-T) server by a first interactive network television network time protocol (NTP-I) server and a second NTP-I server; inquiring a first clock offset value with the second NTP-I server according to a preset time interval by the first NTP-I server; inquiring a second clock offset value with the second NTP-I server by the first NTP-I server when the first clock offset value exceeds a preset time difference threshold; and correcting a local clock by the first NTP-I server when the second clock offset value exceeds the preset time difference threshold. The invention can well keep the clock synchronization of the NTP server and avoids the clock disorder of the system.

Description

technical field [0001] The invention relates to the technical field of network television, in particular to a network time protocol (NTP) server clock synchronization maintenance method, system and device. Background technique [0002] Many business processes of Interactive Personality TV (IPTV) depend on the clock, such as time-shifting service, review service, subscription service and other main services. With the rapid development of IPTV, Network Time Protocol (Network Time Protocol, NTP) servers are also under increasing pressure and responsibility. The NTP server needs to provide NTP clock synchronization of each IPTV server, and also provide NTP clock synchronization of a set top box (Set Top Box, STB). Since the time after the STB is turned on is 1970 by default, the NTP server is configured to not limit the time difference and still provide NTP clock synchronization service. [0003] The NTP server (hereinafter referred to as NTP-I server) of IPTV is configured to...
