This invention discloses a streaming tag computation method based on event-driven and
metadata-driven approaches, addressing issues such as poor real-time performance in
IPTV tag management, high rule modification costs, untraceable status, and difficulties in
tag system expansion. This invention constructs a real-
time data stream access platform and a tag rule
metadata repository, decoupling rules from computation tasks; it generates real-time computation tasks based on
metadata-driven approaches and completes incremental tag computation through event-driven mechanisms; it supports dynamic hot updates of rules, establishes a closed-loop
management system for the entire tag lifecycle, and designs a unified
data model and
hybrid storage architecture for multiple tag types. This invention pioneers a collaborative mechanism between event-driven streaming incremental computation and metadata-driven hot updates, achieving tag synchronization latency ≤1 second, a 90% improvement in rule modification efficiency, and 100%
traceability of status transitions, providing
IPTV operations with real-time, flexible, and controllable tag capabilities.
