    Abstract: Systems for testing set-top boxes and content distribution networks are provided. In general, systems and methods are described for simulating a set-top box subscriber base, remotely controlling the operations of the set-top boxes of the simulated subscriber base, and analyzing the quality of transmissions received by the set-top boxes. Houses, streets, and towns are simulated using multiple set-top boxes connected to a network. A controller is configured to remotely instruct the set-top boxes to access content from the network and to monitor the operations of the set-top boxes, and an analyzer is configured to monitor the quality of the transmissions received. Methods are also provided for testing set-top boxes and content distribution networks and for testing the quality of transmissions from one source as compared to another source.
