    摘要： A device is configured to receive a request for particular content metadata; determine, in response to the request, whether information associated with the particular content metadata is stored in a local memory; present the particular content metadata for display without contacting a server when the information has been stored in the memory for less than a first amount of time; present the particular content metadata for display and contact a server to obtain new content metadata when the information has been stored in the memory for at least the first amount of time and less than a second amount of time; and contact a server to obtain new content metadata, relating to the particular content metadata, and present the new content metadata for display when the information has been stored in the memory for at least the second amount of time.
