Method and apparatus for creating an electronic program guide based on a channel profile

摘要

A method and apparatus for building an electronic programming guide based on statistical information about the history of broadcasted programs where the programming information is obtained on the basis of currently available schedule information and where a broadcast system spreads programming information across a plurality of transport streams. Each time a user changes a channel, a new transport stream potentially becomes available, and current scheduling information is taken from that stream to update a profile of programming for that particular stream. New programming information that is transmitted on other channels is stored whenever the user selects one of those channels. In this manner, an electronic programming guide is eventually built based on the programming information available on the channels accessed by the user.
