Network based digital information and entertainment storage and delivery system

Abstract

Live television broadcast and other information and entertainment programs, e.g., videos-on-demand (VOD), are provided to a user through a communications network, e.g., a cable network. A processing unit is employed at an headend of the communications network to respond to user requests for PVR-like functions, e.g., pausing, rewinding and fast-forwarding, to be performed on the program content being viewed. The processing unit in accordance with the invention causes a delivery of an appropriate version of the program content to meet such user requests.

Description

RELATED APPLICATIONS[0001]The present application is a continuation of U.S. application Ser. No. 10 / 263,015, which was filed on Oct. 2, 2002, will issue on Mar. 15, 2011 bearing U.S. Pat. No. 7,908,626, and claims the benefit of U.S. Provisional Application No. 60 / 377,963 filed on May 3, 2002, which are assigned to the assignee of the present application and are incorporated by reference herein.FIELD OF THE INVENTION[0002]The invention relates to communications systems and methods, and more particularly to a system and method for delivering information and entertainment programs through a communications network, e.g., a cable network.BACKGROUND OF THE INVENTION[0003]Personal video recorders (PVRs), e.g., TiVO and ReplayTV devices, are popular nowadays, stemming from their capabilities of “pausing”, “rewinding” and “fast-forwarding” live television (TV) broadcast while it is being recorded. They may also offer such other functions as “one-touch programming” for automatically recordin...

Benefits of technology

[0011]The user may also reserve, for later review, not only in-progress programs and future programs as in prior art, but also previously broadcast programs since they have been recorded at the headend regardless of any user request. In addition, by removing the program recording function from a local device, e.g., a prior art PVR, to the network, the user no longer needs to be bothered with the local device (or its remote control for that matter), and may also reserve programs having overlapping broadcast times. Thus, with the invention, a user advantageously can enjoy any desired programs anytime, thereby transcending traditional program schedule limitations.

[0012]It is an object of the invention to provide interactive functions, e.g., PVR-like functions, to enhance a user's program enjoyment. It is another object of the invention to provide effective user interfaces for realizing such services as program reservation, music and video on-demand services, searching, media content downloads, distance learning, out-of-market programming, picture-in-picture (PIP) programming, on-line commerce, etc. It is still another object of the invention to facilitate effective organization of, and access to, programming information. To that end, a user is provided, e.g., with an interactive program guide for quickly accessing program line-up information, and graphical user interfaces (GUIs) for organizing favorite shows, program channels, etc. It is a further object of the invention to receive user feedbacks on programs and commercials for statistical analysis. It is another object of the invention to take advantage of the network communications facilities to provide a messaging service to the network users.

Problems solved by technology

Although prior art PVRs offer such attractive functions as pausing, rewinding and fast-forwarding “live” TV broadcast (collectively hereinafter “PVR-like functions”), we have recognized certain disadvantages associated with use of the PVRs.

For example, one such disadvantage is that like a VCR, a PVR is a standalone device which requires yet another remote control to operate the device, in addition to those remote controls for a TV set, set-top box, DVD player, VCR, etc., which already proved to be confusing to a user.

Another disadvantage is that a prior art PVR only records (a) the last X minute program material played on the channel to which the user actually tunes, where X represents a limited value, and (b) desired programs which need to be identified to or by the PVR in advance of their broadcast.

Thus, any program material other than (a) or (b) is not recorded by a PVR, thereby limiting the materials that a user can review.

Still another disadvantage is that limited by the number of tuners therein, a prior art PVR is not capable of recording programs in their entirety which have overlapping broadcast times and the number of which is greater than the number of tuners, thereby further limiting the materials that a user can review.
