A digital television (DTV) receiver retrieves, from a memory, a standardized hostname and a standardized filename for a web-based service for providing a channel map associated with service providers. The DTV receiver adds, to the standardized hostname, a name for a particular service provider and sends, to a data server, a request for channel map information, where the request is based on the standardized hostname, the name for the particular service provider, and the standardized filename. The DTV receiver receivers, from the data server, a channel map file based on the standardized filename and extracts information from the channel map file to present to a user.
