Abstract

A content storage method and system for use in a content distribution network are provided. A personal file locker is established on the network for a user. A content-storage-request database is established. The database tracks requests by the user for placing video programs into the user'"'"'s file locker for personal use by the user. Upon the broadcasting of a video program for which there exists a request by the user to place the video program into the user'"'"'s file locker, the requested video program is stored in the user'"'"'s file locker. The stored video program is then made available to the user for viewing. Alternative approaches to content storage methods and systems are also described, including the use of a buffer enhancement to enable the performance of operations on “live” television.

3. The method of claim 1 further comprising:

enabling the user to fast-forward broadcast programming during the broadcasting thereof via utilization of the buffer enhancement, thereby further personalizing the viewing of an otherwise traditionally delivered program.

4. The method of claim 1 wherein the utilization of the buffer enhancement is initiated by the user viewing broadcast programming such that programming is only stored to the file locker upon the viewing thereof unless the programming is the subject of a specific request by the user for placement in the file locker.
