This invention provides technology for more effectively transmitting or receiving advanced digital broadcasting services. [Solution] A time control method for a broadcast receiving device capable of receiving broadcast waves in which 4K broadcast services and 2K broadcast services are simultaneously broadcast via a broadcast transmission line, wherein the device receives the 4K broadcast service transmitted in the MMT format included in the broadcast wave, demodulates it, and displays the broadcast program of the 4K broadcast service; it receives the 2K broadcast service transmitted in the MPEG2-TS format included in the broadcast wave, demodulates it, and displays the broadcast program of the 4K broadcast service; and performs time control to control the clock synchronization process of the 4K broadcast service and the clock synchronization process of the 2K broadcast service, wherein the time control is configured to continue the clock synchronization process of the 2K broadcast service even when the broadcast program of the 4K broadcast service is being displayed, and to continue the clock synchronization process of the 4K broadcast service even when the broadcast program of the 2K broadcast service is being displayed.

This invention relates to the field of emergency warning broadcasting technology, specifically an intelligent emergency warning broadcasting system, comprising: a data fusion module for receiving and parsing raw warning data streams to generate composite warning event objects; an impact range analysis module for spatially overlaying the object with a static geographic feature layer to dynamically identify target broadcasting units; a content generation module for matching templates based on event types and generating formatted warning text; an instruction scheduling module for allocating resources and generating broadcast instruction sets based on the real-time online status and channel load of the target broadcasting units; and an instruction execution module for issuing the instruction set to trigger emergency broadcasting. This system achieves accurate determination of the warning range based on real-time geospatial calculations and reliable instruction issuance adaptively based on network status, improving the accuracy and timeliness of warning delivery.
