The Roundbox Broadcast Server provides a centralized interface for the ingestion and distribution of application data. The server interfaces with the broadcast network to manage the delivery of data, invoking encryption, content protection, and other necessary services. The server combines data from multiple applications for transmission over the network, optimizing bandwidth utilization based on the quality of service required for each application. The server allows the network operator to establish fine-grained bandwidth management policies governing how network bandwidth is allocated.

For the TV Guide ESG solution, the Roundbox Broadcast Server enables the widest range of Electronic Service Guide deployment scenarios. The server aggregates programming data and delivers the ESG to the handset over the broadcast network. It supports existing standard formats including DVB-IPDC (CBMS) and OMA BCAST.
