Electronic program guide subsystem for receiving and processing electronic program guide information from a set-top box
First Claim
1. A digital video recorder connectable to a set-top box configured to receive electronic program guide information and broadcast audiovisual data, the set-top box including at least one auxiliary interface that supports communication between the digital video recorder and the set-top box, the digital video recorder comprising:
- at least one recorder interface connectable to the auxiliary interface;
a storage device;
a microprocessor configured to control the digital video recorder and the set-top box, the microprocessor comprising an electronic program guide subsystem connected to the recorder interface to receive the electronic program guide information from the set-top box and to process the electronic program guide information to schedule recording the broadcast audiovisual data on the storage device; and
a video output interface separate from the recorder interface, the video output interface connectable to a display device.

Abstract
An electronic program guide processing device is connectable to a set-top box configured to receive electronic program guide information. The set-top box includes at least one auxiliary interface that supports communication between the electronic program guide processing device and the set-top box. The electronic program guide processing device includes at least one device interface connectable to the auxiliary interface. The electronic program guide processing device further includes an electronic program guide subsystem connected to the device interface to receive and process the electronic program guide information from the set-top box. In one aspect, a digital video recorder is connectable to a set-top box configured to receive electronic program guide information and broadcast audiovisual data. The set-top box includes at least one auxiliary interface that supports communication between the digital video recorder and the set-top box. The digital video recorder includes at least one recorder interface connectable to the auxiliary interface, and includes a storage device. The digital video recorder further includes an electronic program guide subsystem connected to the recorder interface to receive the electronic program guide information from the set-top box and to process the electronic program guide information to schedule recording the broadcast audiovisual data on the storage device.
