Control system for network servers

摘要

A system is provided for the generation and transmission of data to a number of items of electrical apparatus, such as broadcast data receivers. The system comprises a network to which a number of servers are connected. The servers are controlled to issue data for distribution through the network to the broadcast data receivers. On the basis of the data received, the broadcast data receivers adopt an operating configuration. The broadcast data receivers are provided with memory which is adapted to identify when incorrect data is issued by a server and identify the particular server or servers which issued the data.
