Claim:
1. An information processing apparatus, comprising: a broadcast interface to receive broadcast content from a broadcast facility; a processing device, having a demultiplexer and a number of decoders, to process the received broadcast content; a communication interface to communicate with an external server by way of a network; and a controller that is capable of acquiring from the broadcast facility an application to which an electronic signature is attached and in which location information necessary for acquiring from the external server an application processed together with the broadcast content is stored, validating the electronic signature, and acquiring the application from the external server by way of the network based on the location information in a case of succeeding at least in the validation, in which application mode information is associated with the application, the application mode information representing a first mode or a second mode, the first mode being indicative of a broadcast linking type application which is capable of using a broadcast function and the second mode being indicative of a broadcast non-linking type application which is incapable of using the broadcast function, in which the controller is configured to determine whether validation of the electronic signature is required or not based on whether the mode information represents the first mode or the second mode, such that the controller determines that the validation of the electronic signature is not required when the application mode information represents the first mode and the controller determines that the validation of the electronic signature is required when the application mode information represents the second mode, in which the broadcast facility is separate from the external server, and in which the information processing apparatus is separate from the broadcast facility and the external server.
