Program reservation-and-recording device, information-providing server, program reservation-information management server, program reception device, and program reservation recording system

摘要

There is provided a program reservation recording device capable of reducing load on a server and performing program recording as is reserved by a user. Immediately before the reserved program is started and immediately before the end of it (S 1 ), the program reservation recording device makes a request to an information providing server connected via a general-purpose network so as to acquire the latest program list (S 2 ). The program reservation recording device compares the reservation information indicating the program reservation contents (start time, end time, etc.) to be stored in a memory with the latest program list acquired (S 3 ). If any mismatch is present, the reservation information is updated according to the program list (S 4 ).
