Claim:
A method for updating data comprising: receiving, at a device, an address associated with an Internet site from a broadcast signal; connecting from the device to a server using said address; extracting a time point corresponding to data associated with the Internet site from the server; determining whether the Internet site was previously identified by determining whether data associated with the previously identified Internet site and a first time point corresponding to the data associated with the previously identified Internet site were previously stored in a memory of the device; if the Internet site was not previously identified: storing the received address and the extracted time point corresponding to data associated with the Internet site in the memory of the device, and if the Internet site was previously identified: comparing previously stored time point corresponding to the data associated with the received address of the Internet site from the memory of the device to the extracted time point; receiving the data associated with the Internet site from the server if the previously stored time point is different from the extracted time point; automatically updating the previously stored data associated with the Internet site based on the received data; and informing that the previously stored data was updated.
