Fragmented Ad Systems, Rising Operational Costs
As media service have evolved, various applications and advertising models such as IPTV and OTT, live channels and VoD, and FAST have emerged, driving growth in the advertising business. However, as each service has been developed sequentially and independently, operational systems have become increasingly fragmented, and the separation of systems by business model has compounded operational complexity.
In particular, cost increases from various factors, including dual subscription processes, fragmented reporting, and infrastructure usage fee,s have been major causes of significantly reduced operational efficiency.
Three Core Values Created by Integration
CASTIS's unified ad platform flexibly integrates three key areas to address these challenges:
Operational Integration: Manage all advertising business at a glance through a dashboard, and operate campaigns, creatives, and products from a unified interface.
System Integration: Standardize integration with various external systems related to advertising business to eliminate data silos and provide sophisticated targeting.
Data Integration: Collect, aggregate, and statistically process distributed data to secure real-time business insights.

Proven Global References

Completing the Ad Ecosystem with End-to-End Solutions
Beyond simply providing a platform, CASTIS offers End-to-End solutions that support the entire process from ad decision to delivery, reporting, and settlement.

OPEX Optimization Through legacy Resource Virtulization
CASTIS enables maximum utilization of already-invested available resources. In particular, the CDN infrastructure built by Castis is a priority resource that can be utilized by the ad operations platform. This approach significantly reduces cloud usage costs by falling back to external cloud resources only when the capacity of these virtualized resources is exceeded. Additionally, we support both Unicast/Multicast streaming to ensure both reliability and efficiency through hybrid ad delivery methods best suited to the customer's service environment.
Conclusion

It's about creating a competitive advertising business by improving operational efficiency, minimizing OPEX, and strengthening platform stability.
