Method and device for synchronizing data increment of internet protocol TV

Abstract

本发明公开了一种交互式网络电视数据量增量同步方法及装置,其中方法包括:系统预设一数据同步阀值;当到达定时处理时间时,若对比出本周期系统更新时间戳大于上一个周期的处理时间戳,或者,上一个周期的过滤窗格不为一预设值,确定本周期的过滤窗格;所述本周期的过滤窗格对应的同步数据量小于或等于所述数据同步阀值;确定本周期同步数据;将所述本周期同步数据发送给客户端。本发明保证每个周期内同步数据量小于或等于数据同步阀值,在时间上均衡分担了系统各设备的压力,避免了瞬时系统负担峰值过重,提高了系统性能。
The invention discloses a method and device for synchronizing data increment of an internet protocol TV (IPTV). The method comprises the following steps: a system presetting a data synchronize threshold; when achieving the fixed processing time, determining the filter pane of the period if the system update time stamp of the period is more than the processing time stamp of the previous period through contrast, or the filter pane of the previous period is not a preset value, wherein the synchronous data volume corresponding to the filter pane of the period is less than or equal to the data synchronize threshold; determining the synchronous data of the period; and sending the synchronous data of the period to a client. The invention ensures that the synchronous data volume in each period is less than or equal to the data synchronize threshold, shares the pressure of each equipment of the system in time on average, avoids the instantaneous system from bearing overweight peak and improves the system performance.
