Abstract
Channel lineup information in a television system is efficiently managed with an internal electronic program guide manager (IEM). The IEM creates and maintains an internal electronic program guide (EPG) information database for a user program preference determination engine (PDE), which is resident in a STB, DTV or PVR. The internal EPG data are for use by software agents of the PDE only. The external EPG is used for a graphical user interface display. First, external channel lineup information is received from an external program guide; from that, internal channel lineup information is generated that contains less information than the external channel lineup information, yet sufficient information to render the internal channel lineup information useful in the internal database management system; and the internal channel lineup information is updated upon receiving notification of a change to the external channel lineup information.
