- the storage device 160 of the preferred embodiment illustrated in Figure 1 is a rotating storage drive (e.g., a hard disk drive).
- the storage device 160 can be a writable digital video disk (DVD) drive, or a device that utilizes another technology that provides writable non- volatile storage.
- the DVR microprocessor 230 of the preferred embodiment utilizes the results from a preference determination engine, as well as DVR user input 265, to control the operation of both the digital video recorder 100 and the set-top box 110.
- the preference determination engine is an algorithm, enabled in hardware, software, or both, which monitors a user's viewing patterns to create a user profile of the user's watching preferences.
- the preference determination engine is resident in the DVR microprocessor 230.
- the preference determination engine recommends particular television programs which the user may be interested in watching. These recommendations assist users to schedule their recording schedules by alerting them to upcoming programs of interest.
- the digital video recorder 100 can be configured to automatically record these programs without further input from the user.
- An example of a preference determination engine is MbTVTM sold by Metabyte Networks, Inc. of Fremont, CA.
- the DVR microprocessor 230 accesses the EPG information 120 from the EPG subsystem 170.

- the STB microprocessor 210 is effectively slaved to the DVR microprocessor 230.
- Figure 2 schematically illustrates an EPG subsystem 170 compatible with the preferred embodiment of the present invention.
- the EPG subsystem 170 comprises an EPG processor 280, an EPG manager 290, and an EPG storage buffer 300.
- the EPG processor 280 communicates with the STB microprocessor 210 via a communications protocol which utilizes messages transmitted across the recorder interface 150 and the auxiliary interface 140 to transfer EPG information 120 from the set-top box 110 to the digital video recorder 100.
- the EPG processor 280 can decode encoded EPG information 120, enact compression/decompression utilities to optimize the storage and transfer of EPG information 120, or perform other process operations on the EPG information 120 from the set-top box 110. In such embodiments, the user is presented with processed EPG information.
- the EPG manager 290 compiles the EPG information 120 received from the set-top box 110 into a database, which is stored in the EPG storage buffer 300.
- the EPG manager 290 accesses the EPG information 120 stored in the EPG storage buffer 300 in response to commands from the DVR microprocessor 230, and makes requested EPG information 120 available to the DVR microprocessor 230.
- the DVR microprocessor 230 utilizes the EPG information 120 to provide the user with broadcast scheduling information and to provide the preference determination engine with the EPG information 120 required to compile a user profile of the user's watching preferences and to enable automatic recording of programs of interest. In this way, the EPG manager 290 processes the EPG information 120 to schedule recording the broadcast audiovisual data 130 on the storage device 160.
- the EPG storage buffer 300 is stored on the storage drive 160.
- the EPG storage buffer 300 is stored in whole or in part in random-access memory resident with the DVR microprocessor 230.
- the digital video recorder 100 of the preferred embodiment does not require a modem to receive EPG information 120 from a third-party source. Therefore, the digital video recorder 100 avoids the complexity and costs associated with prior art digital video recording systems.
- the service provider remains in control of the information displayed to the user because the digital video recorder 100 utilizes the EPG information 120 received from the service provider, as opposed to a third-party source.
- the format of the broadcast scheduling information can then be similar to the format presented by the set-top box 110 in video systems without a digital video recorder 100.
- the similarity between formats provides a more seamless transition for the user upon adding a digital video recorder 100 to the user's video system.
- This retention of control by the service provider can be particularly important economically in embodiments in which advertising information is transmitted to the digital video recorder 100 along with the EPG information 120 (i.e., where control of what the user is viewing can be translated into advertising revenue and opportunities for pay-per-view sales).
- the STB microprocessor 210 continually monitors the EPG information 120 received by the video input interface 180, and stores a portion of the EPG information 120 in RAM resident with the STB microprocessor 210.
- the STB microprocessor 210 When the STB microprocessor 210 detects that new or updated EPG information 120 has been received, the STB microprocessor 210 stores the new or updated EPG information 120 in resident RAM, and sends a "New EPG data available" message to the EPG processor 280, which responds by returning an "Acknowledge response" message. After the EPG processor 280 has been informed that there is new or updated EPG information 120 available, the EPG processor 280 can request that the new or updated EPG information 120 be sent by the STB microprocessor 210 to the EPG processor 280 by sending an "EPG data request" message to the STB microprocessor 210. The STB microprocessor 210 responds by sending an "EPG data response" message which contains the requested new or updated EPG information 120.
- the digital video recorder 100 is continually provided with up-to-date EPG information as soon as such information is transmitted to the set-top box 110 by the service provider.

- This connection of the recorder interface 150 to the auxiliary interface 140 provides a conduit for communication between the STB microprocessor 210 and the DVR microprocessor 230, broadcast audiovisual data 130, and EPG information 120.
- the connection of the digital video recorder 100 to the set-top box 110 is recognized by the STB microprocessor 210 through communication between the STB microprocessor 210 and the DVR microprocessor 230. In the preferred embodiment of the present invention, this communication is in the form of messages sent from the DVR microprocessor 230 to the STB microprocessor 210.
- the EPG information 120 is communicated from the set-top box 110 to the EPG subsystem 170. In certain embodiments, the EPG subsystem receives updated EPG information 120 from the set-top box 110, where the set-top box 110 is configured to detect updated EPG information 120.
- the EPG subsystem 170 receives EPG information 120 that is selectively transmitted by the set-top box 110 via the auxiliary interface 140 and the recorder interface 150. Additionally, in certain embodiments, this selective transmitting of the EPG information 120 by the set-top box 110 is in response to a request signal transmitted by the EPG subsystem 170, or in response to user input.
