DIGITAL VIDEO RECORDER SYSTEM WITH AN INTEGRATED DVD RECORDING DEVICE
First Claim
1. A process for a digital video recorder (DVR) incorporating an integrated digital video device (DVD) player/recorder, comprising:
- accepting analog and/or digital television broadcast signals by a plurality of input signal tuners in a DVR;
wherein each of the tuners is individually tuned to a specific broadcast signal;
storing specific broadcast signals as digital program material on a hard disk in the DVR;
wherein a DVD player/recorder resides in the DVR;
determining indexes of frames for a broadcast signal as the broadcast signal is being stored as digital program material;
storing the indexes along with the digital program material on the hard disk;
receiving a user selection of one or more program material stored on the hard disk to be transferred to the DVD player/recorder; and
writing the one or more selected program material along with associated indexes onto a DVD inserted into the DVD player/recorder.

Abstract
A digital video recorder (DVR) system with an integrated DVD recording device accepts TV input streams in a multitude of forms. Analog TV streams are converted to an MPEG formatted stream for internal transfer and manipulation, while pre-formatted MPEG streams are extracted from the digital TV signal and presented in a similar format. Indexes within the MPEG stream are determined and saved at predefined intervals and are stored on a hard disk along with the MPEG program material and used to create navigation packets when writing to a DVD inserted in an integrated DVD player/recorder. When a program is requested for display from the hard disk or the integrated DVD player/recorder, the program material are extracted from the appropriate source and reassembled into an MPEG stream which is sent to a decoder. The decoder converts the MPEG stream into TV output signals and delivers the TV output signals to a TV monitor. User control commands are accepted which affect the flow of the MPEG stream allowing the user to view stored programs with special functions: reverse, fast forward, play, pause, index, fast/slow reverse play, and fast/slow play. The user can select program material stored on the hard disk to be written to a DVD and can also select program material stored on a DVD to be transferred to the hard disk.
