Method to Record Multiple Shows at the Same Time Using a PVR

Disclosed is a method for recording overlapping television shows using a personal video recorder (PVR). Personal Video Recorders are becoming more popular at home. Broadband cable modem access is also a popular choice for households to connect to the internet. Many cable companies offer a service where subscribers can rent a PVR. An attractive use of this method is for cable companies to sell it as a service to cable subscribers who rent a PVR.

A typical PVR has two recorders that can be used at the same time. It is still possible that a user will want to watch more programs than the PVR can record at one time. With the proliferation of TV channels and the expensive nature of TV shows, many shows are being several times a day or week or on alternate channels. For example, a TV show aired on Tuesdays at 8 CST on one network and on the following Mondays at 10 CST on another network.

Using this method, if the user wants to record more shows at once than the PVR provides recorders, the PVR will record part of the show at one showing and record the rest of the show at subsequent showings. This will allow the customer to record and watch more shows than is currently possible.

For Example:

User wants to record Shows A-E. The PVR contains 2 recorders. The numbers indicate the priority of that show for that time slot.

In this example, Show A receives the highest priority for its time slot, and can be recorded using recorder 1. Show B receives the second highest priority (for the conflicting time slot, but the highest priority for the time 4-4:30) and can be recorded using recorder 2. Show D has the highest priority for the 7-8 timeslot (recorder 1) with Show E getting the second highest priority for that slot (recorder 2).

Prior to this idea the user would be unable to schedule Show C for recording. Using this technique, the last hour of Show C is recorded from 5-6 and then composed with the first half hour after it is recorded at 6:30-7.

Scheduling the recording The first problem that must be solved is how to schedule the recording of the bits of the show. A priority will be assigned to each show that the user schedules. Shows that are automatically scheduled to be recorded based on similarity to the user's profile receive a

penalty to their priority ranking. When scheduling conflicts are detected (this is determined by the number of recorders (r) available on the PVR, r + 1 videos requested concurrently), the scheduling software scans the TV listings for the next week looking for matches for the conflicting programs. For episodic shows, the show and episode title...
