Abstract
A network digital video recording (nDVR) system may take into account the capabilities of a requesting user's local DVR when managing network recordings. The user's local DVR may include a temporary buffer that is normally used to record what the DVR is tuned to, and may be used for local trickplay functionality such as pausing live television. The nDVR features described herein may track the usage of the user's temporary DVR buffer, and use that in determining what to stream in response to a user's playback request. The nDVR system can also determine if the user's local DVR has an unused tuner at a time of a program recording, and can instruct the user's local DVR to also tune to the program.
